All financial information in this AIF is prepared in accordance with accounting principles generally accepted in Canada (“Canadian GAAP”).

Currency

All dollar amounts are expressed in Canadian dollars unless otherwise indicated.

Note Regarding Forward Looking Statements

This AIF contains “forward-looking statements” which represent expectations or beliefs of the Company about future events. These statements can be identified generally by forward-looking words such as “expect”, “believe”, “anticipate”, “plan”, “intend”, “estimate”, “may”, “will” or similar words. Information concerning the interpretation of drill results and mineral resource estimates also may be deemed to be forward-looking statements, as such information constitutes a prediction of what mineralization might be found to be present if and when a project is actually developed. Forward-looking statements are statements about the future and are inherently uncertain, and actual achievements of the Company or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors,

including, without limitation, those described in Item 5 of this AIF under the heading, “Risk Factors”, and elsewhere in this AIF.

The Company’s forward-looking statements contained in this AIF are made as of the respective dates set forth in this AIF. Such forward-looking statements are based on the beliefs, expectations and opinions of management as of the date the statements are made. For the reasons set forth above, investors should not place undue reliance on forward-looking statements.

Mineral Symbols

Au – gold; Ag – silver; Cu – copper; Fe – iron; Hg – mercury; Mo – molybdenum; Na – Sodium; Ni – Nickel; O – Oxygen; Pd – palladium; Pt – platinum; Pb – lead; S – Sulphur; Zn – Zinc.

Mineralization, Mineralized material, mineralized deposits or Deposit

A mineralized body which has been intersected by sufficient closely spaced drill holes and/or sampling to support sufficient tonnage and average grade of metal(s) to warrant further exploration-development work. This mineralized body does not qualify as a commercially mineable ore body, as prescribed under Securities and Exchange Commission standards, until a final and comprehensive economic, technical and legal feasibility study based upon the test results is concluded and supports Proven/Probable Mineral Reserves.

Mineral Deposit

A mineralized body which has been delineated by appropriate drilling and/or underground sampling to support a sufficient tonnage and average grade of


Augusta Resource Corporation – Annual Information Form Page 4



metal(s). Under SEC standards, such a deposit does not qualify as a reserve until comprehensive evaluation, based on unit cost, grade, recoveries and other factors, concludes economic feasibility.

Molybdenite

The primary ore of molybdenum with chemical composition MoS2.

Net Smelter Royalty (NSR)

A royalty payment made by a producer of metals, normally to a previous property owner, based on gross mineral production from the property, less deduction of certain costs.

Paleozoic

An era comprising the Cambrian to Permian systems.

Permian

The youngest period of the Palaeozoic

Preliminary Feasibility

A comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, has been established, and where an effective method of mineral processing has been determined. This Study must include a financial analysis based on reasonable assumptions of technical, engineering, operating, and economic factors and evaluation of other relevant factors which are sufficient for a Qualified Person acting reasonably, to determine if all or part of the Mineral Resource maybe classified as a Mineral Reserve.

Pyrite

The most common and widely distributed sulfide mineral with composition FeS2.

Refractory Ore

Ore that resists the action of chemical reagents in the normal treatment processes and which may require pressure leaching or other means to effect the full recovery of the valuable minerals.

Renierite

A sulfide mineral with contained copper, zinc and germanium. (Cu,Zn)11 (Ge,As)2 Fe4 S16.

Scheelite

A tetragonal mineral, CaWO4 , with molybdenum replacing tungsten toward powellite CaMoO4 ; a source of tungsten.

Skarn

The minerals commonly present in a skarn include iron oxides, calc -silicates (wollastonite, diopside, forsterite), andradite and grossularite garnet, epidote, and calcite. Many skarns also include ore minerals; several productive deposits of copper or other base metals have been found in and adjacent to skarns. The typical rock of a skarn is hornfels, a fine-grained, flinty rock produced by the heat and solutions given off by the intruding magma.

Sphalerite

The most common zinc mineral with composition ZnS.

Stratigraphic

Pertaining to the composition, sequence, and correlation of stratified rocks.

Sulphide

A compound of sulphur with another element, typically a metallic element or compound.

Vein

A tabular or sheet-like mineral deposit with identifiable walls, often filling a fracture or fissure.


Augusta Resource Corporation – Annual Information Form Page 5


National Instrument 43-101 Definitions

Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 (“NI 43-101”). The definitions given in NI 43-101 are adopted from those given by the Canadian Institute of Mining Metallurgy and Petroleum.

Mineral Reserve

The term “mineral reserve” refers to the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. The study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that might occur when the material is mined.

 

Mineral Resource

The term “mineral resource” refers to a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge.

 

Measured Mineral Resource

The term “measured mineral resource” refers to that part of a mineral resource for which quantity grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

 

Indicated Mineral Resource

The term “indicated mineral resource” refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

 

Inferred Mineral Resource

The term “inferred mineral resource” refers to that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

 

Qualified Person

The term “qualified person” refers to an individual who is an engineer or geoscientist with at least five years of experience in mineral exploration, mine development, production activities and project assessment, or any combination thereof, including experience relevant to the subject matter of the project or report and is a member in good standing of a self-regulating organization.

ITEM 3: GENERAL DEVELOPMENT OF THE BUSINESS

Three Year History - Significant Acquisitions/Dispositions

Due to the overall depressed market environment for junior resource companies, the Company was basically inactive throughout 2001. During the first two quarters of 2002 the Company optioned interests in 13 properties aggregating approximately 1.7 million acres of land strategically located in the Coronation Diamond District area play located in Nunavut, Canada, around the kimberlite exploration finds of Ashton, Kennecott, DeBeers and others. The Company formed an alliance with Ashton Mining (Northwest Territories) Ltd. whereby Ashton would undertake the initial work programs (to be funded by the Company) on six properties and then have the option to acquire a 60% interest in the properties over several years. The Company believed that Ashton’s expertise, experience and resources in the Coronation Gulf district would allow for cost effective and systematic exploration of the Company’s properties.

During 2002 the Company raised $615,000 through private placements and $100,000 through a loan. However, this was insufficient for the Company to meet its obligations and as a result seven properties aggregating 971,559 acres were returned to the vendors. The Company continued to hold interests in six properties covering over 728,000 acres.

Augusta Resource Corporation – Annual Information Form Page 8


Most of 2003 was spent attempting to acquire mineral exploration properties to complement the Company’s interests held in the Coronation Diamond District. During 2003, the Company raised $346,500 of which $195,000 was through the issue of flow-through shares, providing the ability to undertake the initial work expenditures on the AW and BH properties comprising over 240 acres. Results of the initial work program did not prove favourable and no further work was recommended. The agreement with Ashton with respect to the AW and BH properties was terminated and the Company wrote-off the costs effective June 30, 2004.

The Company also has four separate option agreements with 4763 NWT Ltd. (“NWT”) to acquire working interests (“WI”) of 10% and 20% for four properties located in the Coronation Diamond District in Nunavut, Canada, which aggregate about 487,300 acres in the region. Various third party exploration companies (“Primary Optionees”) were provided an option to earn their interest by completing work over a 3 to 4 year period providing the Company a carried interest in these properties pending the Primary Optionee’s earning their interest. However, to date, the Primary Optionees have not supplied the Company with reports of work performed on these properties. In addition, as interest in the exploration area has diminished, the Company does not plan on conducting any work on these properties.

In December of 2004, the Company announced it had entered into an agreement to acquire the Mt. Hamilton Gold Project, located in White Pine County, Nevada. The terms of the acquisition were US$3.6 million payable with US$3,000,000 in cash payable over a two year period and 3,750,000 units. The units had a deemed value of US$0.16. Each unit consisted of one share and one warrant. Each warrant entitles the holder to purchase one common share at US$0.16 for a period of two years expiring on May 6, 2007. The Company also assumed an underlying NSR and minimum advance royalty payments. Prior to commencement of commercial production the Company will pay minimum advance royalty payments of US$100,000 per annum commencing November 19, 2005 and continuing until November 19, 2010, when the annual payment amount increases to US$300,000. Upon commencement of commercial production, the Company will pay a base rate of 3% NSR, subject to increase whenever the price of gold is greater than US$400 per ounce.

On January 26, 2005, the Company announced it had entered into an agreement to acquire the Shell Deposit, molybdenum-gold property in White Pine County, Nevada, located approximately 1,000 meters from its Mt. Hamilton property. The Company is acquiring a 100% working interest, subject to an underlying NSR ranging from 0.5% - 4.5% for cash payment of US$120,000, and annual advance royalty payments commencing at US$80,000 on the first anniversary increasing by $20,000 per year until production commences.

In March 2005, the Company entered into an agreement to acquire the Lone Mountain, copper-zinc-silver property in New Mexico. The Company acquired a 100% working interest, subject to an underlying NSR ranging from 2.0% - 3.0%, minimum exploration commitments of US$4,850,000 over a 3 year period with the first US$500,000 to be expended in the first nine months from signing the agreement, and aggregate payments of US$1,000,000 cash and 325,000 common shares over a three year period, prior to the property being placed in commercial production. In addition, until the property is in commercial production, the Company will make payments of US$400,000 cash and 100,000 common shares on the fourth and each subsequent anniversary. The cash payments during the first three years is as follows: US$100,000 on completion of the agreement, US$200,000 on the first anniversary of the agreement, US$300,000 on the second anniversary of the agreement, and US$400,000 on the third anniversary of the agreement; The share payments are as follows: 50,000 common shares issued on completion of the agreement, 75,000 common shares issued on the first anniversary of the agreement, 100,000 common shares issued on the second and third anniversary of the agreement.

In June 2005 the Company entered into an Option Agreement to purchase the Rosemont Ranch copper deposits in Pima County, Arizona. The Company has the right to purchase a 100% working interest in the property (which includes patented and unpatented claims, fee land and surface grazing rights) subject to a 3% NSR, for cash payment of US$20,800,000 payable over a three year period. The Company is not required to make the payments, but the option would terminate and the Company would surrender any claims to the property if it fails

Augusta Resource Corporation – Annual Information Form Page 9


to make the payments. The Company has made the first payment of US$6,666,666. The next payment of $7,200,000 is payable on July 29, 2006 and the balance of US$6,933,334 is payable on July 29, 2007.

During 2005 the Company raised approximately $17 million in gross proceeds through private placements and a convertible debenture to complete the initial cash payments and work expenditures for the Rosemont, Mt. Hamilton, Lone Mountain and Shell projects.

Three Year History of Financings

The Company has financed its operations through funds raised in loans, public/private placements of common shares or units (consisting of commons shares and warrants exercisable for common shares), shares issued for property, shares issued in debt settlements, and shares issued upon exercise of stock options and share purchase warrants.

In addition the Company raised $46,250 from the exercise of stock options and $1,130,916 from the exercise of warrants during the fiscal year ending December 31, 2005. During the years ended December 31, 2004 and 2003 the Company did not raise any funds from the exercise of stock options or warrants.

ITEM 4: NARRATIVE DESCRIPTION OF THE BUSINESS

The Company is engaged in the acquisition, exploration and if warranted, development of natural mineral resource properties. It currently holds or has the options to acquire 100% interest in the following properties:

Augusta Resource Corporation – Annual Information Form Page 10


These properties are in the exploratory stages and are thus non-producing and consequently do not generate any operating income or cash flows from operations. The Company depends on equity capital to finance its activities.

The following is a narrative description of each property:

The Rosemont Property

Acquisition by Augusta

The Company entered into an Option Agreement dated April 18, 2005 with Rosemont Ranch, LLC, Lazy Y I Ranch, LLC, TWW Investments, LLC, DAS holdings, LLC, Habibi LLC and West Santa Rita Land, LLC for the right to purchase a 100% working interest in the Rosemont Property, Pima County, Nevada, USA (which includes patented and unpatented claims, fee land and surface grazing rights), subject to a 3% NSR, for cash payment of US$20,800,000 payable over a three year period. The Company is not required to make the payments but the option would terminate and the Company would surrender any claims to the property if it fails to make the payments. The Company has made the first payment of US$6,666,666 on July 29, 2005. The next payment of US$7,200,000 is payable on July 29, 2006 and the balance of $6,933,334 is payable on July 29, 2007.

The Company retained Wardrop Engineering Inc. (Wardrop) to review and evaluate existing geological data that pertains to the Rosemont Property, including historical resource estimates and to prepare an independent technical report. The review included an examination of all known and available data and a site visit. The technical information in the following section concerning the Rosemont Property is derived from the Technical Report on the Rosemont Property dated August 16, 2005 (Revised) (the “2005 Rosemont Technical Report”). Mr. Gregory Z. Mosher, P.Geo. of Wardrop was responsible for the preparation of the 2005 Rosemont Technical Report. The 2005 Rosemont Technical Report is available on SEDAR at www.sedar.com.

Property Description and Location

The Rosemont Property is located about 50 kilometers southeast of Tucson, Arizona, at approximately 31º 50’ North longitude, 110 º 43’ West latitude. The Property is comprised of 144 Patented Mineral Claims in six parcels, (2,050.14 acres), 850 contiguous unpatented lode claims (approximately 12,000 acres), and five parcels of fee surface rights (910.96 acres), with an aggregate area of approximately 14,960 acres (6,060 hectares). The legal description of the property is as follows: Patented Mining Claims: Townships 18 and 19 South, Ranges 15 and 16 East. Surface Rights: Township 18 South, Range 16 East: Section 14 NE ¼ & SW ¼; Section 15 E ½ less highway; Section 21 NE ¼; Section 23 SE ¼; Section 27 SE ¼ of SE ¼; Section 32 N1/2 SW ¼, S ½ NW ¼ and NE ¼ NW ¼ Unpatented lode claims: Townships 18 and 19 South, Ranges 15 and 16 East.

The patented claims and surface tenure (fee land) have been surveyed, as have the majority of the unpatented claims. The property contains four known skarn-type copper occurrences, the Rosemont, Broadtop Butte, Copper World and Peach–Elgin, of potential economic significance, all generally contained within the area of the patented claims. The unpatented lode claims are renewable annually on September 1, at a cost of US$150 per claim. The patented and fee surface rights are taxed as grazing lands at an annual rate of less than US$2,000. There are two net smelter royalties payable on the patented mining claims as well as the bulk of the non-patented mining claims: 1.5% to Franco-Nevada Mining Co, and 1.5% to Chicago Trust Co.

Access, Climate and Local Resources

Augusta Resource Corporation – Annual Information Form Page 11


The Property is accessible from the east and west. From Tucson, the eastern access is southeast for 30 kilometers (km) via Interstate 10 and then south for about 20 km via State Highway 83. The western portion of the Property is most readily accessible from the west, via the Tucson – Nogales highway for about 30 km to Sahuarita and then easterly for about 20 km. A network of unpaved access roads exists within the property.

The area has a semi-arid climate, with annual precipitation of about 20 centimeters, most of which falls as rain during June through August, and December through February. Temperatures range from about four degrees Celsius in December – January to about 40º Celsius during July and August.

Mining has been a significant industry in southern Arizona since the 1800s, and several large open-pit mines are currently operating within 30 kilometers of Tucson. It is therefore reasonable to assume that all necessary materials and skills necessary for a mining operation are locally available.

Geologic Setting and Mineralization

The Rosemont Property is underlain by Paleozoic and Mesozoic -age sedimentary rocks that have been intruded by Tertiary-age intrusives. The Paleozoic stratigraphic sequence ranges from Cambrian-age Bolsa Formation quartzite to carbonate and sandstone of the Rain Valley Formation of Permian age. The Devonian to Permian sequence is comprised of the Martin, Escabrosa, Horquilla, Earp, Colina, Epitaph and Concha Formations, in all of which limestone is the predominant rock type, with subordinate dolomite, siltstone, sandstone and shale. The Escabrosa, Horquilla, Earp and Colina Formations are the principal hosts of copper mineralization on the Rosemont Property.

All known mineral occurrences within the Rosemont Property are skarn-type and are contained within skarn-altered carbonate strata of Mississippian to Permian age that are spatially associated with an altered quartz latite porphyry. Copper is the most significant economic mineral; molybdenum and silver are present in possibly recoverable quantities. Gold content is negligible.

Four skarn-type copper deposits occur within the Rosemont Property. From south to north these are the Rosemont, Broadtop Butte, Copper World and Peach–Elgin. All four deposits are described as having similar characteristics with respect to geology and mineralization. The Rosemont and Peach–Elgin have been explored in greater detail than the Broadtop Butte and Copper World, and of the two, Rosemont is better known. The Rosemont mineralization occupies an area of about one square kilometer, and extends down-dip for at least 1,200 meters. Stratigraphically, mineralization extends over 100 meters.

Chalcopyrite and pyrite are the primary sulphide minerals. Bornite, molybdenite, sphalerite, galena and scheelite are present in subordinate amounts. Trace amounts of silver and gold are also present. Sulphides occur principally as veinlets, coarse disseminations, blebs and clots within irregular lenticular zones within and generally parallel to lime-silicate intervals. Magnetite is present in varying amounts throughout the skarn zone.

History – Exploration and Drilling

Documented mining activity in the Property area dates from the late 1880s. Underground mining operations produced copper until 1951 during which time about 227,000 tons of ore were processed at an average grade of 3.8% copper. During the late 1950s activity on the property consisted of mainly exploration and development drilling. In 1963 Anaconda Mining Company acquired the property and carried out an extensive mapping and drilling program. Anaconda and Amax formed the Anamax Mining Company in 1973 and through Anamax generated most of the modern information on the mineralization in the Rosemont area, including the delineation of the Rosemont deposit. Anamax sold the property to a real estate company in 1986, which in turn sold it to Asarco in 1988. Asarco conducted exploration, primarily in the Rosemont and Peach–Elgin areas, re-estimated the Rosemont mineral inventory, and in 1996 initiated a mine permitting process. Work on the Property effectively

Augusta Resource Corporation – Annual Information Form Page 12


ceased in 1997 following a precipitous drop in copper price, and Asarco sold the property to a real estate company in 2004. Augusta optioned the property from the real estate company in 2005.

About 570 holes have been drilled within the Rosemont Property. Original logs and assays are available for many of these holes. Split core from an unknown number of drill holes has also been preserved. No information is available regarding core sampling methodology and data verification is also not possible.

As most of the drilling was done by large reputable mining companies that specialized in exploration and mining of porphyry/skarn-type deposits, it is assumed that sampling conformed to the standard industry practice of the time and assay data is considered to be of acceptable quality for the same reason.

The Rosemont deposit has been tested by about 130 vertical and angle diamond drill holes. The Peach– Elgin deposit has been tested by about 207 holes. Prior to 1964, 67 vertical churn and core holes had been drilled. Subsequent drilling amounted to 140 vertical and angle core holes. The balance of the 570 holes have tested the Broadtop Butte and Copper World deposits as well as an unknown number of other prospects and old mines within the area. The allocation of these holes is not known.

The 2005 Rosemont Technical Report references two historical resource estimates that were carried out for the Rosemont deposit: (1) Pincock, Allen & Holt (PAH) conducted a computer-based reserve estimate of the Rosemont deposit in 1977; and (2) In 1997 The Winters Company (Winters), on behalf of Asarco Inc., conducted an “Order of Magnitude” study for mining the Rosemont deposit. Both were carried out in a rigorous manner and are considered relevant in demonstrating the technical merits of the Property.

Since acquiring the Rosemont Property in June 2005, Augusta completed a drill program of approximately 9,000 meters to verify the historic resource and to develop an updated modern resource estimate. Details of this resource estimate are provided below under “Since the Acquisition by Augusta.”

The Peach-Elgin deposit contains an estimated sulphide resource of about 13.7 million tons with an average grade of 0.78% copper at a cutoff grade of 0.4% copper.

The Broadtop Butte deposit contains an estimated mineralization of 8.8 million tons with an average grade of 0.77% copper and 0.037% molybdenum, at a cutoff of 0.4% copper. This estimate and that for Peach-Elgin are considered relevant but not compliant with NI 43-101 and should not be relied upon.

Environmental

As an advanced exploration development property, Rosemont is up to date and compliant with its environmental obligations and as such there are no material environmental liabilities.

In order to conduct drill work programs on the property, permits are necessary. Responsible government agencies are the State of Arizona Department of Water Resources, and the federal US Forest Service (if drilling on public lands). Water rights are an integral part of the property title, although it is not known what volume of water this may represent. There are a number of water wells on the property, one of which currently produces about 1200 gallons (4.5 meters) per minute.

Should the property reach a stage of commercial viability, the Company will be required to comply with the following federal, state and local regulations prior to entering commercial production:

Federal Mine Plan Approvals - Provisions of the General Mining Law of 1872, the Federal Land Policy and Management Act of 1976, the Mining and Mineral Policy Act of 1970; and the National Materials and Minerals

Augusta Resource Corporation – Annual Information Form Page 13


Policy, Research and Development Act of 1980 authorize mining on public lands under an approved Mine Plan of Operations provided that all other federal, state and local environmental permits and authorizations are received.

Environmental Impact Statement - The land required for mining the open pit is privately held. Adjacent public land will be required for milling, utility corridors, access roads, waste rock and tailing disposal, and other incidental operations. Acquiring the right to use and occupy several thousand acres of this public land will require completion of an Environmental Impact Statement (EIS). Completion of an EIS for Rosemont operations will include public scoping, community involvement, technical analysis, field data collection and reporting, endangered species consultation as needed, public notice and comment periods, and publication of the Draft EIS and the Final EIS.

Threatened and Endangered Species Review - The U. S. Fish and Wildlife Service and Arizona Game and Fish Department maintain lists of Special Status Species; threatened, endangered, proposed endangered, candidate, and conservation agreement species. Mine plans will be subject to review for avoidance or mitigation of impacts to protected species.

Aquifer Protection Permit - ADEQ requires that potentially discharging facilities are subject to environmental review under the Aquifer Protection Permit Program. This process must demonstrate that discharging facilities will not cause an exceedance of aquifer water quality standards. In addition to this technical demonstration, groundwater quality monitoring will be required during operations and through mine closure. A detailed closure plan is required to show how water quality will be protected after mine operations are completed.

Air Permits - Mining operations must obtain an air quality control permit from Pima County which has been delegated authority by the Arizona Department of Environmental Quality. The permit will contain provisions for emission control equipment or practices, recordkeeping and reporting procedures and monitoring.

Water Quality and Stormwater Permits - Stormwater discharge permits and Stormwater Pollution Prevention Plans will be required for an open pit mining operation.

Army Corps 404 Permit - Three major washes and several tributaries will require crossings of jurisdictional waters to access the site. Other washes and ravines will be affected by mine pit and rock storage piles. The total sum of the jurisdictional area for Section 404 will require that Rosemont obtain an individual permit from the US Army Corps of Engineers.

Arizona Department of Transportation (ADOT) Access Road Approvals - To improve the road access from the existing state highway, Augusta must follow the ADOT permit process for review and approval of construction along an existing scenic highway.

Mine Reclamation and Closure Plans and Financial Assurance - Mine closure plans are required as part of the Federal Mine Plan of Operations as well as by the Arizona State Mine Inspector and the Arizona State Department of Environmental Quality. The State Mine Inspector Reclamation Plan requires a detailed plan showing what post-mining land uses will be possible on the mined out lands, and must include a program for achieving those post-mining land uses. Federal and state reclamation closure plans require a financial assurance instrument to demonstrate financial ability to complete the reclamation program as described in the closure plans. There are interagency agreements to allow for each agency to recognize the financial assurance held by other agencies, so that duplicate bonding is not required.

Cultural Resources - All lands required for mine construction and operation will require clearance for cultural resources. The process includes field survey for locating cultural resource sites, and testing of sites determined to contain significant cultural information potential.

Augusta Resource Corporation – Annual Information Form Page 14


Local Permits and Approvals - Several local agencies will be involved in the approval process through Pima County Development Services. These agencies regulate floodplain encroachments, drainage improvements in washes, grading land clearing for roadways and erosion control and impacts to water quality in streams.

Impact of Permitting Process on Rosemont Project - The time to complete the permit application and review process can be affected by potential public controversy, difficult or unresolved technical issues, legal challenges, changes in operating plans, or unforeseen environmental impacts that are not readily mitigated.

At the end of the environmental review process, the responsible official from each agency must sign a permit, issue a Record of Decision (ROD) or provide some other form of documentation approving, denying, or modifying the permit application. Typically, the approving permit document authorizes a specific project component, and may include a list of conditions and permit requirements that mitigate or minimize the environmental issues determined to be significant in the review analysis. These conditions can affect project schedule, economics, and feasibility.

Since the Acquisition by Augusta

The Company commenced drilling on the Rosemont deposit in August 2005, to carry out a program of confirmation and in-fill drilling initially totaling 3,000 metres in size, designed to verify the historic resources and to develop an updated modern resource estimate. On September 19, 2005 the Company extended the drilling program to approximately 9,000 metres in order to test down dip extensions to the main Rosemont open pit copper/molybdenum/silver deposit and add new measured and indicated resources. All drilling and assaying was done under a strict quality assurance and quality control (QA/QC) protocol that includes independent lab analysis on sawn diamond drill core.

The deposit outcrops at its western edge and follows the orientation of the host rocks, dipping beneath arkosic rocks to the east. Previous closely spaced drilling programs have defined the shallow, western portion of the deposit, but have left the eastern, deeper extension less well defined On October 13, 2005 the Company announced assay results for the first three holes, which test the down-dip extension and include the following:

The drilling has been successful in extending the ore zone and verifying the geologic model for the deposit. The drilling was designed to provide sufficient drill density in order to maximize the measured and indicated resource that would fall within the boundaries of a floating cone pit optimization. Total drilling on the deposit now stands at 78,720 meters.

These drill results have been prepared under the guidance and supervision of Mike Clarke, Vice President of Exploration for the Company. Dr. Clarke is the designated Qualified Person.

The 2005 drill program was conducted to finalize the identification of measured and indicated resources in the main zone (where a future pit would start) and to develop measured and indicated resources down-dip in order to provide the resource base for a larger pit. The Company is currently conducting a pre-feasibility study in order to advance the development of the Rosemont copper project towards open-pit production.

On January 24, 2006 the Company announced its 2006 Rosemont Deposit Mineral Resource Statement. Significant improvements are reflected in the Statement (excluding satellite deposits) when compared with the historic resource reported by Anamax (Pincock, Allen and Holt – 1977). The completion of the 2005 exploration program enabled the remodeling of the deposit and a new estimation of mineral resources. The following results reflect a potential single open pit, exclusive of the other satellite deposits on the property:

The drilling program confirms Rosemont as one of the best undeveloped open pit copper projects in the world and the only significant undeveloped one in the U.S. Data from the 2005 drill program has provided the Company with a better understanding of the geology of the deposit. The information and experience will be applied to the exploration for extensions of the Rosemont deposit and satellite deposits. The Company will focus first on an area of prime exploration potential that extends 1.4 km north of the Rosemont deposit to the Broadtop Butte prospect, where old Anamax drilling defined another significant historical copper/molybdenum resource on the property.

Augusta Resource Corporation – Annual Information Form Page 18


A reported average silver grade of 7.2 g/ton was reported in the 2005 drill hole program. However, silver was assayed only sporadically in the historic work; therefore, there is insufficient data to categorize a silver resource at this time. The Company is excited about the silver potential of the deposit and further assay work is planned to establish a resource.

Augusta retained WLR Consulting, Inc. (WLRC) of Lakewood, Colorado to estimate the Rosemont Project mineral resources as a part of a pre-feasibility mining study that is presently in progress. The mineral resource estimation work was performed by or under the direction of Mr. William L. Rose, P.Eng., WLRC’s Principal Mining Engineer and an independent Qualified Person under the standards set forth by NI 43-101.

The Mt. Hamilton Property

Acquisition by Augusta

On April 20, 2005 the Company entered into a Share Purchase Agreement with Diamond Hill Investment Corp. to acquire 100% interest in the Mt. Hamilton Gold Project, located in White Pine County, Nevada. The Company purchased the Mt. Hamilton Gold Project by purchasing 100% of the shares of DHI Minerals Ltd., which owned 100% of DHI Minerals (U.S.) Inc., the holder of the property. The terms of the acquisition are US$3,600,000 payable as to US$3,000,000 in cash over two years (a payment of US$500,000 was paid upon execution of the formal Share Purchase Agreement and the balance of payments are due on the first two anniversary dates of the Agreement); 3,750,000 common shares at US$0.16 per share, and 3,750,000 warrants to purchase common shares with an exercise price of US$0.16 per share for a period of two years expiring on May 6, 2007. Under the terms of the acquisition the Company also assumed the underlying NSR and minimum advance royalty payments to Centennial Minerals Company, LLC. Prior to commercial production, the Company will pay US$100,000 per annum commencing on November 19, 2005 and continuing until November 19, 2010 when the annual payment amount increases to US$300,000 per annum. Upon commencement of commercial production, a base rate of 3% NSR is payable, subject to an increase whenever the price of gold is greater than US$400 per ounce. The NSR shall increase by one half of one percent for each US$50 increment to a maximum of 8% NSR. The Company has the option to purchase up to one and one half percentage points of the NSR for US$2,000,000.

The Company commissioned Roscoe Postle Associates Inc. (“RPA”) to review relevant reports and data on the property, site visit and prepare an independent technical report compliant with NI 43-101 on the Mt. Hamilton Property. The technical information in the following section concerning the Mount Hamilton Property is derived from the Report on the Mt. Hamilton Property dated February 24, 2005 (the “2005 Mt. Hamilton Technical Report”) authored by Mr. Stewart Wallis, P.Geo, Mr. Gregory Z. Mosher, P.Geo. and Mr. David W. Rennie, P. Geo.. At the time the report was prepared, Mr. Mosher was with RPA but is now with Wardrop. The 2005 Mt. Hamilton Technical Report is available on SEDAR at www.sedar.com.

Property Description and Location

The Mt. Hamilton Property is located 40 miles west of Ely, Nevada, and is comprised of nine surveyed patent mineral claims, totaling 120.57 acres and 21 un-surveyed mining claims, that total 405.24 acres located in Sections 15, 16, 21, 22, 27, Township 16N, Range 57E, White Pine County, Nevada.

The Property is located in the western flank of the White Pine Mountains at the head of Seligman Canyon, between 8,500 ft. to 9,000 ft. above sea level. The former mill site and leach pad are located on the alluvial fan at the mouth of Seligman Canyon at about 6,800 ft above sea level.

Augusta Resource Corporation – Annual Information Form Page 19


Access, Climate and Local Resources

The property is easily assessable year round by a series of paved and maintained gravel roads.

The climate is semi-arid, with an average precipitation total of 9.5 inches. Most of the precipitation falls as snow during the period December through March and averages 49 inches. A severe snowstorm could hinder work during the winter months. Temperatures range from about 9°F in winter to a summer maximum of about 87°F.

There is no infrastructure remaining on the property. Mining supplies and experienced workers are available in Ely and elsewhere in the State of Nevada.

Geological Setting and Mineralization

The Mt. Hamilton Property is located at the south end of the Battle Mountain Gold Trend and is underlain by gently folded Cambrian-age sedimentary rocks that have been intruded by two granitoid, Cretaceous-age stocks, the Seligman and Monte Cristo.

Stratigraphic units in the area include the middle Cambrian Eldorado Dolomite, Geddes Limestone, and Secret Canyon Shale, and the upper Cambrian Dunderberg Shale. The Secret Canyon Shale, principal host of precious metal mineralization, is at least 1,000 ft. thick and consists of four units: basal, thin-bedded greenish shale; thin-bedded limestone with shale partings; thin-bedded greenish shale; and an uppermost unit of interbedded limestone and shale.

The Seligman stock is elongated in a north-south direction and comprised of medium-grained hornblende-biotite granodiorite containing small silicified breccias. The Monte Cristo stock, located about 4,000 ft. southwest of the Seligman stock, is a biotite granite porphyry containing extensive stockworks of quartz flooding.

The area has been affected by at least two periods of deformation. Late Mesozoic to early Tertiary compression resulted in the formation of broad, north-trending folds as well as thrust faults. Late Tertiary Basin and Range faulting has uplifted the White Pine Range along north-striking high-angle normal faults.

The host of the mined out NE Seligman deposit as well as the remaining peripheral mineralized zones is the upper part of the Secret Canyon Shale (Hamburg Dolomite unit) near the contact of the Dunderberg Shale where it has been metamorphosed to a pyroxene-garnet-tremolite-quartz-potassium feldspar calcite skarn.

The Centennial deposit is contained entirely within skarn-altered Hamburg Dolomite and mineralization is localized along zones of retrograde alteration that may have developed on low-angle structures.

Mineralization at Mt. Hamilton consists of skarn-hosted Mo, Cu, WO3, Au and Ag. Gold occurs predominantly in zones of retrograde alteration and to a minor extent, in pro-grade garnet-pyroxene skarn. The retrograde alteration zones are comprised of a quartz-goethite-epidote-calcite assemblage that replaces garnet-pyroxene skarn. Gold grades within the retrograde alteration range from < 0.01 oz/ton Au to more than 1 oz/ton Au.

History, Exploration and Drilling

Phillips Petroleum Co. acquired the property in 1968 and, from 1968 to 1982, drilled over 100,000 ft. and identified a tungsten-copper-molybdenum deposit that was in part coincident with a portion of the later-defined Centennial deposit.

Rea Gold Corporation (Rea) acquired Mt. Hamilton Mining Company in June 1994, and gold production commenced from the Seligman deposit in November 1994. Production by Rea from start-up in 1995 to September

Augusta Resource Corporation – Annual Information Form Page 20


1997 is reported to be 83,260 ounces of gold. Rea had planned to commence mining the Centennial deposit in 1997 which contains measured and indicated resources at a 0.016 oz/ton Au cut-off of 12 million tons grading 0.034 oz/ton Au. These data are historical in nature and were compiled before the implementation of NI 43-101 reporting standards, are not compliant with NI 43-101 and should not be relied upon.

Rea encountered mining and recovery problems during the mining of the Seligman orebody and as a result ceased mining in June 1997 but continued leaching through September 1997, when it declared bankruptcy. Centennial Minerals Company LLC acquired the property in 2003.

The Centennial deposit has been outlined by 303 reverse circulation (RC) drill holes and 11 HQ diameter core holes which include the 1997 program that amounted to 32 RC holes totalling 12,755 ft. and 1,091 ft. in three diamond drill core holes. Descriptions of the sampling methodology and sample preparation indicate that the work was carried out according to the standard industry practices in common use at that time. Analytical methods used by Westmont were standard fire assays carried out at Cone Geochemical or Chemex, both recognized laboratories. Rea analyses, carried out at the mine laboratory, also included soluble cyanide gold assays prior to fire assaying those samples above 0.009 oz/ton Au.

For the 1997 program, the mine laboratory was the primary analytical facility but MRDI set up a rigorous QA/QC program consisting of internal standards, rig duplicates, check assays and pulp duplicates. MRDI reports that although the data are not numerous, the sample preparation and analytical procedures were adequate for use in resource estimations. RPA has reviewed and accepted the database as used for MRDI in its resource estimation and considers it appropriate for use in an estimate of Mineral Resources.

Several series of metallurgical tests have been carried out on Centennial mineralization. Additional work carried out in 1996 by Kappes Cassidy & Associates consisted of nine column leach tests grading 0.038 to 0.108 oz/ton Au. Two tests at -1/2 in. crush, averaged 81.7% gold recovery and seven tests at -1 in. crush averaged 76.5% gold recovery.

Cyanide consumption for the two batches averaged 1.58 and 1.09 pounds per short ton (lb/st) respectively with lime consumption reported at 2.14 and 3.86 lb/st respectively. No silver results were reported.

RPA reviewed the most recent estimate of Mineral Resources for the Centennial deposit carried out in 1997 by MRDI. MRDI based the classification of the resources on acceptable industry parameters under the Australasian Code for Reporting of Identified Mineral Resources and Ore Reserves which RPA considers similar to the CIM definitions. RPA reclassified the resources in the 2005 Mt. Hamilton Technical Report as provided in the following to conform to the CIM definitions as required by NI 43-101:

Note: Ag grade and contained ounces are in terms of NaCN soluble Ag.

Resources in the above table are stated at three cut-off grades. The 0.016 oz/ton cut-off is typical of those used on similar heap leach deposits in the Western US but has not been validated at Centennial at this time. Until an economic evaluation is completed, the economic cut-off for this deposit is unknown. Mineral resources which are not mineral reserves do not have demonstrated economic viability.

RPA reviewed the methodology and is of the opinion that the resource estimate as stated in Table 1 is compliant with NI 43-101 and that the classifications used meet the definitions of Mineral Resources as defined by the CIM.

The various Seligman deposits have been essentially mined out and, although there may be resources left in the bottom of the Seligman pit, RPA was not been able to quantify them.

A complete data review is required to establish exploration targets, but currently several exploration targets including the deep potential at the Seligman, Centennial, Fiveway and Chester prospects have been identified and require further evaluation.

Environmental

The Company is unaware of any outstanding environmental liabilities. The Mt. Hamilton Property has been extensively reclaimed. All evidence of infrastructure has been removed and the pads and dumps have been contoured as necessary and reseeded. A Plan of Operations from the US Forest Service (USFS) will be required for any trenching, road building or drill program. A reclamation bond, the amount depending on the amount of disturbance, will be required prior to commencement of the program. RPA understands that permission from the USFS is required to use the existing haul road and a substantial bond may be required to be posted. There are also other access roads into the property.

Since the Acquisition by Augusta

Mt. Hamilton has multiple exploration targets including surface bulk mineralization as well as high-grade vein style mineralization. Six separate high priority areas have been identified. An extensive amount of exploration and drilling information on these areas is included in the acquisition of the Property. The Company plans to drill

Augusta Resource Corporation – Annual Information Form Page 22


approximately 3,000 metres of diamond core to verify previously discovered mineralized bodies and explore their extensions. Permit applications are in place for this drilling program and approval is expected during early 2006. Data acquisition and compilation from earlier exploration programs has been completed.

The Lone Mountain Property

Acquisition by Augusta

Augusta entered into an option agreement with Thornwell Rogers, MRP Geo Company LLC and South Branch Resources, LLC dated April 19, 2005 to acquire the Lone Mountain copper-zinc-silver property in New Mexico. The Company has the right to earn a 100% working interest in the Lone Mountain Property by making a series of cash payments totaling US$1 million and share payments totaling 325,000 common shares of Augusta to the Property owners over a period of three years, and by undertaking work commitments of US$4,850,000 over the same period. On subsequent anniversaries of the agreement, pending commencement of commercial production, Augusta will pay to the owners US$400,000 and 100,000 common shares of Augusta. Upon commencement of commercial production Augusta must pay to the Property owners the greater of US$100,000 or a 2% NSR on all state or private mineral lands, and a 3% NSR on all federal (Bureau of Land Management (“BLM”)) mineral lands. With respect to the work commitments, the Company must expend US$500,000 within the first nine months from signing the agreement. The cash payments during the first three years are as follows: US$100,000 on completion of the agreement, US$200,000 on the first anniversary of the agreement, US$300,000 on the second anniversary of the agreement, and US$400,000 on the third anniversary of the agreement. The share payments during the first years are as follows: 50,000 common shares issued on completion of the agreement, 75,000 common shares issued on the first anniversary of the agreement, 100,000 common shares issued on the second and third anniversary of the agreement.

Wardrop Engineering Inc. (Wardrop) was retained by the Company to conduct due diligence including compilation and review of all available documentation, do a site visit and review existing drill core and prepare an independent technical report. The technical information in the following section concerning the Lone Mountain Property is derived from the Technical Report on the Lone Mountain Property dated August 16, 2005 (Revised) (the “2005 Lone Mountain Technical Report”). Mr. Gregory Z. Mosher of Wardrop is responsible for the preparation of the 2005 Lone Mountain Technical Report. The 2005 Lone Mountain Technical Report is available on SEDAR at www.sedar.com.

Property Description and Location

The Lone Mountain Property is located in Grant County, New Mexico, Township 18 south, Range 13 west, Sections 17, 19, 20, 21, 29, and 30. The Property is located eight kilometers southeast of the town of Silver City, 15 kilometers southwest of the Chino open pit and eight kilometers northwest of the Hurley Copper smelter and is comprised of two New Mexico State Mineral Leases, HG-0054 -T18S, R13W, Section 17 (640 acres) and HG-0055 -T18S, R13W, NE¼, NE¼ of NW¼ Section 20 (240 acres); and, 40 BLM Lode Mining Claims LM 1-40, T18S, R13W, Sections 19-21with a total area of approximately 610 acres (247 hectares). The total area of the Property is 1,490 acres (603 hectares).

Three patented mining claims, Corliss, El Campo, and Sweet Home, are located within the area of the present lode mining claims. These patented claims and the surface rights to Section 20 do not form part of the Property. Wardrop has not seen a title report for the Property and therefore cannot confirm the veracity of the Property status.

Augusta Resource Corporation – Annual Information Form Page 23


Access, Climate and Local Resources

The Property is readily accessible. Silver City is about 360 kilometers southwest of Albuquerque via Interstate 25 and paved Highway 152. It is also about 150 kilometers northwest of the city of Las Cruces to which it is connected by Interstate 10 and Highway 180. The Property is located about three kilometers south of Highway 180 on the eastern outskirts of Silver City. The access road from Highway 180 to the property is paved for about 1.5 kilometers of this distance, the balance is an unpaved road that continues to the south boundary of the Property. A number of four-wheel tracks branch from this road and provide ready access to most parts of the Property, including the area in which all the drilling has taken place to date.

A 115 KV power line that supplies the Chino Mine to the northeast, passes through the southeast corner of the Property. Silver City is a mining center that serves the nearby Chino Mine and supported several former mines in the area including the Tyrone Mine, located about eight kilometers to the southwest. Most needs of an operating mine can therefore be expected to be met within the immediate area. Water rights for the area are fully allocated and the pumping or use of water for a mining operation at Lone Mountain would require the purchase of existing rights.

Southwestern New Mexico has a continental, semiarid to semi-desert climate. Average temperatures in the Silver City area are two degrees Celsius in winter and 22 degrees Celsius in summer. Annual precipitation is about 40 centimeters, mostly as rain.

Surface rights are privately held and access to the property and the terms of use of the surface for any exploration or production activities must be negotiated with the surface owners.

Geological Setting and Mineralization

The primary host is the Mississippian-age Lake Valley Formation limestone that has been altered by prograde skarn formation on the periphery of a latite stock of Cretaceous to Tertiary age, and by subsequent retrograde quartz-calcite-pyrite-magnetite-hematite alteration, assumed to also be genetically associated with the emplacement of the stock. Chalcopyrite and sphalerite are the primary minerals of economic interest and are associated with retrograde alteration. A second, deeper occurrence of copper mineralization of potential economic interest is contained within skarn-altered dolomite and shale belonging to the El Paso, Montoya and Fusselman Formations of Ordovician to Silurian age.

Within the area of the lode mining claims, south of the main area of economic interest, Cretaceous-age Colorado shale and underlying Lake Valley Limestone of Mississippian age are exposed in a northwest-trending belt of outcrop.

The southern portion of the State Mineral Leases is underlain by a buried, elliptical Tertiary age monzonite porphyry stock that measures about 1500 meters northeast-southwest, and about 500 meters along the short axis. This stock has intruded sedimentary rocks of Cambrian to Cretaceous age, and andesitic volcanics of Cretaceous to Tertiary age. The stock is spatially associated with felsic sills and dikes.

The mineralization of primary interest is contained within the Lake Valley Formation limestone that is comprised of two members, the upper Tierra Blanca, a white, medium to coarse-grained crinoidal limestone, and a lower chert-nodule bearing member.

Copper and zinc sulphide mineralization occurs within skarn-altered carbonate strata belonging to the Lake Valley, Fusselman and El Paso Formations on the northeastern margin of the intrusive. Copper – zincmineralization of potentially economic significance occurs at depths of 500 to 1000 meters below surface.

Augusta Resource Corporation – Annual Information Form Page 24


Distribution of mineralization appears to be controlled by lithology, alteration, and structural setting. By comparison with similar mineralization in the area, it is reasonable to expect that the distribution of that mineralization is complex.

History – Exploration and Drilling

The main period of mining in the area began in 1875 and has continued, with interruptions to the present time. Exploration of the Lone Mountain Property began in 1975 by Bear Creek Mining Company to test the hypothesis that historic manganese-silver occurrences and a large magnetic anomaly were indicative of a buried porphyry system. During the period 1975–1978, Bear Creek and associated companies drilled 18 core and percussion holes (4,982 meters). In 1979 Getty and Coastal Mining drilled and deepened four holes for a total of 8,070 meters. During 1982–1983, Chevron Resources Company drilled and deepened three holes (4,042 meters). Bear Creek drilled two holes (213 meters) in 1985. Granges drilled two holes (1,249 meters) in 1989, and the last drilling was done in 1997 when Clark Arnold drilled four rotary holes (731 meters). In total, 33 holes with an aggregate length of 19,287 meters were drilled, most at 305-meter (1000 feet) centers, and a few fill-in holes at separations of about 150 meters (500 feet). In addition to the drilling, an induced polarization survey was carried out in 1963, and an aeromagnetic survey in 1976. There has been no known work on the Property since 1997.

In summary, exploration to date appears to have identified a zone of potentially economic mineralization within the Lake Valley Formation, but too few holes have been drilled to permit an accurate estimation of the mineral inventory.

The 2005 Lone Mountain Technical Report references the following information:

In 1983 Chevron Resources calculated “drill-indicated” and “potential” resource estimates for the Lake Valley and underlying Fusselman – El Paso (Lower Paleozoic) Zones. These classifications do not meet the standards of NI 43-101 and are included for purposes of historical reference. For the Lake Valley, at a cutoff of 1% copper, Chevron calculated a “drill-indicated reserve” of 7.4 million tons with a grade of 2.2% copper, 5% zinc and 1.2 ounces per ton silver, and a “total potential” reserve of 18 million tons at the same grade.

The Fusselman – El Paso estimates at a cutoff of 1% copper were “drill-indicated” reserves of 17.5 million tons at an average grade of 1.36% copper, 0.22 ounces per ton silver, and 0.004 ounces per ton gold, and “total potential” reserves of 35 million tons at the same grade. At a cutoff grade of 0.5% copper, the Fusselman – El Paso “drill-indicated” reserve was estimated to be 94 million tons at an average grade of 0.74% copper, 0.13 ounces per ton silver, and 0.002 ounces per ton gold. The “total potential” reserve estimate was 190 million tons at the same grade.

These estimates are considered premature at the present level of exploration and are best regarded as conceptual and should not be relied upon. A significant amount of additional drilling would be necessary to confidently permit interpretation of both the geological setting and the distribution of mineralization within this zone to permit quantification of inferred or indicated resources that are compliant with NI 43-101 definitions.

Environmental

To the knowledge of the Company there are no outstanding environmental liabilities associated with the Lone Mountain Property.

Augusta Resource Corporation – Annual Information Form Page 25


The Property has not been legally surveyed. Surface rights are privately held and access to the property and the terms of use of the surface for any exploration or production activities must be negotiated with the surface owners.

In order to carry out a program for exploration it will be necessary for the Company to acquire permits from both the State of New Mexico and the federal BLM.

Since the Acquisition by Augusta

A Phase 1 drilling program of approximately 3,000 metres of diamond core is anticipated to verify and extend deep, relatively high-grade Cu-Zn mineralization. The permit applications have been submitted and the negotiation for surface drilling access rights are currently being negotiated with private landowners.

Virtually all of the data from previous programs has been acquired and an electronic database and updated geological model have been completed. Scoping level studies will commence upon completion of the Phase 1 drill program for approximately 3,000 metres to verify and extend deep, high grade Cu-Zn mineralization. This program is expected to be complete by May 2006. Currently the Company is in the process of obtaining surface access rights for which negotiations are currently underway with private landowners.

The Company is acquiring a 100% working interest, subject to an underlying NSR ranging from 0.5% -4.5%, for cash payment of $120,000, and annual advance royalty payments commencing at $80,000 on first anniversary increasing by $20,000 per year until production commences. The Shell Deposit located in White Pine County, Nevada was subject to past exploration programs with the latest by Union Carbide Corporation in the early 1980s. The latest historical estimates from 1981 by Union Carbide of indicated and inferred resources using a cut-off grade of 0.35% molybdenum and 0.10 oz gold/ton are as follows:


Zone

Tons
Average
Grade
Molybdenum
Average
Grade Gold

Average
Grade Tungsten
Molybdenum 1,151,774 1.20% 0.01 oz/ton 0.12%
Gold 499,919 0.17% 0.24 oz/ton 0.17%

The Company does, however, plan on verifying the accuracy of these figures by upcoming planned programs.

The figures indicated above are historical. The Company has not done the work necessary to verify the classification of the resource and is not treating the resource figures as a NI 43-101 defined resource verified by a Qualified Person and therefore should not be relied upon by investors.

The Shell Property consists of unpatented claims on public land administered by the US Forest Service. The Shell Property is in an area long recognized as having mineral potential. The established procedures for agency review and approval of mineral exploration proposals are in place and well documented. These agency procedures include review of exploration plans on a case by case basis, and may include requirements for environmental assessment and site surveys before clearance for biological and cultural resources. There are no known environmental factors specific to the Shell Property that would limit mineral exploration, mineral development, or ultimate mineral production from the property.

Augusta Resource Corporation – Annual Information Form Page 26


The geology of the area consists of two Cambrian limestone and shale formations. The oldest formation intercepted by drilling is the Middle Cambrian Eldorado Dolomite, which is reported to be approximately 2,500 feet thick in the Eureka district 40 miles to the west. At Shell the upper part of the Eldorado is commonly stockwork veined with calcite, serpentine, pyrite and magnetite. The Geddes limestone lies above the Eldorado and is host to virtually all of the gold and molybdenum resources at Shell. In addition to expanding the known mineralized horizons with further drilling, discovery potential also exists for mineralized crosscutting features such as mineralized breccia pipes, veins and faults above or below the Geddes horizon. For example drill hole U-17 returned 3.5 feet grading 0.59 ounces gold per ton in a fault bounded breccia above the Geddes horizon. The Shell deposit lies approximately 1,000 meters from the Company’s Mt. Hamilton project and further solidifies its land position in this highly under explored mineralized area.

2006 Plan of Operation

Rosemont Property, Arizona

In 2005 the Company conducted a drill program of approximately 9,000 metres at its Rosemont property to finalize the identification of measured and indicated resources in the main zone (where a future open pit would be pioneered) and to develop measured and indicated resources down-dip in order to provide the resource base for a larger open pit. The program was successful in extending the ore zone and verifying the geologic model for the deposit.

Limited additional exploration drilling is planned for Rosemont during 2006. Data acquired during the 2005 drilling program was integrated into the existing database and a resulting resource calculation was finalized and announced on January 26, 2006. The resource calculation will incur an estimated expenditure of US$50,000. The Company has retained William L Rose of WLR Consulting Inc. and Donald Elkin of Mine Reserve Associates Inc. as independent Qualified Persons to conduct a Mineral Resource analysis. Details of this analysis are provided above under the section titled “The Rosemont Property – Since the Acquisition by Augusta”. The Company has retained Washington Group International Inc. to lead a preliminary feasibility study and Stantec Consulting to develop the environmental, hydrological, closure and permitting plans. The preliminary feasibility study and associated technical report are planned for completion in the second quarter of 2006.

A subsequent full feasibility study and initiation permitting activities are planned for the balance of the year, with related development expenditures estimated at US$5,300,000. In addition, if the Company exercises its right under the Option Agreement on the Rosemont property acquisition, a payment of US$7,200,000 will be required in July 2006. As at September 30, 2005, the Company has expended US$1,121,231 on the Rosemont property. In 2006, total expenditures on the Rosemont property are planned at US$ 12,500,000.

Mt. Hamilton and Shell Properties, Nevada

As the Mt. Hamilton and Shell Properties are adjacent to each other the Company has combined the exploration programs for these properties. The Company believes there are synergies between the two properties from an exploration perspective and from a regional geological perspective. The 2006 exploration plan for the Mt. Hamilton and Shell properties consist of a combined program of approximately 3,000 meters of drilling to verify previously discovered mineralized bodies and explore their extensions. The program will also test a deep manto-like molybdenum deposit identified in previous drilling. Permit applications are in place for this drilling program and approval is expected during the first quarter of 2006.

An updated geologic model and resource report is planned for the Mt. Hamilton Centennial deposit. As of the end of the third quarter ended September 30, 2005 project expenditures on the Mt. Hamilton property were $139,497. Total project expenditures on the Shell property were $12,789.

Augusta Resource Corporation – Annual Information Form Page 27


The estimated costs for the 2006 drilling and studies program total approximately US$400,000. In addition, property acquisition expenses relative to agreements on these properties require payments of US$200,000 on the Shell Property in March 2006 and US$1,200,000 on Mt. Hamilton in April 2006, including annual advance royalty payments. Total expenditures on the Shell and Mt. Hamilton properties are planned at US$1,800,000 in 2006.

Lone Mountain Property, New Mexico

A Phase 1 drilling program consisting of approximately 3,000 meters of drilling is planned for 2006 on the Company’s Lone Mountain property. The program will test the continuity and extension of a previously drilled Cu-Zn-Pb-Ag mineralization hosted in Mississippian-age Lake Valley formation limestone. The permit applications have been submitted and the negotiations for surface drilling access rights are currently underway with the private landowners.

Virtually all of the data from previous programs have been acquired and an electronic database and updated geological model have been completed. Scoping level studies will commence upon completion of the Phase 1 drill program. The Phase 1 program is expected to be complete by May 2006. To date work expenditures on the Lone Mountain property have totalled $38,630.

The projected cost of the exploration program and related activities including the scoping study is approximately US$850,000. In addition property acquisition expenses relative to an option agreement on this property require an option payment of US$200,000 in April 2006. Total expenditures on the Lone Mountain property are planned at US$1,050,000 in 2006.

The Company will continue to fund its operations as it has in the past by way of equity financings and other means that are available in the market place to make its property acquisition and option agreement payments, for exploration and development expenditures on its properties and for working capital and overhead purposes on an ongoing basis as required.

ITEM 5: RISK FACTORS

An investment in the Company's common shares is highly speculative and subject to a number of risks. Only those persons who can bear the risk of the entire loss of their investment should participate. An investor should carefully consider the risks described below and the other information filed with the Canadian securities regulators before investing in the Company's common shares. The risks described below are not the only ones faced. Additional risks that the Company currently believe are immaterial may indeed become important factors that affect the Company's business. If any of the following risks occur, or if others occur, the Company's business, operating results and financial condition could be seriously harmed and investors may lose all of their investment.

We have a history of losses and anticipate that we will continue to incur losses for the foreseeable future.

We have historically incurred losses as evidenced by the consolidated statements of operations contained herein. We incurred losses from operations of $2,972,437, $866,057 and $298,933 for the years ended December 31, 2004, 2003 and 2002, respectively, and $6,360,527 for the nine months ended September 30, 2005. As of September 30, 2005, we had a cumulative net loss from operations of $11,145,814.

Our efforts to date are focused on acquiring and exploring mineral properties. All of our properties are in the exploration stage and none have any known mineral reserves. We do not anticipate that we will earn any revenue from our operations until our properties are placed into production, which is not expected to be for several years, if at all.

Augusta Resource Corporation – Annual Information Form Page 28


We will require additional capital to fund our business plans

As of September 30, 2005, we had working capital of $1,860,780, and estimated working capital of $347,022 as of December 31, 2005. We have no revenues from operations and do not expect to generate any revenues from operations in the foreseeable future. We anticipate that we will require additional capital of approximately $25,000,000 to fund our business activities, including exploration and development expenditures and property payments, during the year ending December 31, 2006. Such funding may not be available on acceptable terms or at all. When required, we intend to raise additional capital through debt or equity financing, and possibly through joint ventures, production sharing arrangements or other means. Our failure to meet our ongoing obligations on a timely basis or raise additional funds that may be required could result in delay or indefinite postponement of further exploration and development of our property or the loss or substantial dilution of our property interests (as existing or as proposed to be acquired).

We have historically depended on distributions of our securities to fund our working capital and funding requirements

Historically, the principal source of funds available to us has been through the sale of their respective common shares. During the years ended December 31, 2005 and 2004, we raised approximately $12,300,000 and $500,000, respectively, by issuing equity securities. We anticipate that we will be required to raise an additional $25,000,000 during the year ending December 31, 2006. Equity financing undertaken by us would cause dilution to our existing shareholders.

In addition, as at December 31, 2005, we had 3,326,833 number of share purchase options at an average exercise price of $1.35 of which 860,583 were fully vested, 15,875,143 warrants at an average exercise price of $1.51, and approximately 1,090,909 common shares further to a convertible debenture outstanding. As a consequence of the passage of time since the date of their original sale and issuance, none of the Company's shares remain subject to any hold period restrictions in Canada as of December 31, 2005. The unrestricted resale of outstanding shares from the exercise of dilutive securities may have a depressing effect on the market for our common shares.

We have no proven or probable reserves and we may never discover sufficient mineral deposits to justify commercialization of any of our properties.

We have no probable or proven reserves on any of our properties, and we have not completed a feasibility study on any of our properties. Therefore, we cannot be certain that minerals will be discovered in sufficient quantities and grade on any of our properties to justify commercial operations. Whether a mineral deposit will be commercially viable depends on a number of factors, some of which are: the particular attributes of the deposit, such as size, grade and proximity to infrastructure; metal prices, which are highly cyclical; and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. If we are unable to upgrade our mineralized material to proven and probable reserves in sufficient quantities to justify commercial operations, we will be unable to develop mines and our financial condition and results of operations could be adversely affected.

We have no history of production and may never place any of our properties into production.

None of our properties are in commercial production, and we have never recorded any revenues from mining operations. We expect to incur losses unless and until such time as our properties enter into commercial production and generate sufficient revenues to fund our continuing operations. The development of mining operations on any of our properties will require the commitment of substantial resources for operating expenses

Augusta Resource Corporation – Annual Information Form Page 29


and capital expenditures, which may increase in subsequent years as needed consultants, personnel and equipment associated with advancing exploration, development and commercial production of our properties are added. The amounts and timing of expenditures will depend on the progress of ongoing exploration and development, the results of consultants’ analysis and recommendations, the rate at which operating losses are incurred, the execution of any joint venture agreements with strategic partners, our acquisition of additional properties, and other factors, many of which are beyond our control. We may not generate any revenues or achieve profitability.

Our exploration activities may not be commercially successful.

Mineral exploration is highly speculative in nature, involves many risks and is frequently nonproductive. Unusual or unexpected geologic formations, and the inability to obtain suitable or adequate machinery, equipment or labor are risks involved in the conduct of exploration programs. We are currently conducting exploration and deposit definition drilling on our properties. The success of mineral exploration is determined in part by the following factors:

Substantial expenditures are required to establish proven and probable reserves through drilling and analysis, to develop metallurgical processes to extract metal, and to develop the mining and processing facilities and infrastructure at any site chosen for mining. Whether a mineral deposit will be commercially viable depends on a number of factors, which include, without limitation, the particular attributes of the deposit, such as size, grade and proximity to infrastructure; metal prices, which fluctuate widely; and government regulations, including, without limitation, regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. We cannot assure you that any gold reserves or mineralized material acquired or discovered will be in sufficient quantities to justify commercial operations.

Exploration, development and mining involve a high degree of risk.

Our operations will be subject to all the hazards and risks normally encountered in the exploration, development and production of gold and other base or precious metals, including, without limitation, unusual and unexpected geologic formations, seismic activity, rock bursts, pit-wall failures, cave-ins, flooding and other conditions involved in the drilling and removal of material, any of which could result in damage to, or destruction of, mines and other producing facilities, damage to life or property, environmental damage and legal liability. Milling operations, if any, are subject to various hazards, including, without limitation, equipment failure and failure of retaining dams around tailings disposal areas, which may result in environmental pollution and legal liability.

The parameters used in estimating mining and processing efficiency are based on testing and experience with previous operations. While the parameters used have a reasonable basis, various unforeseen conditions can occur that may materially affect the estimates. In particular, past operations indicate that care must be taken to ensure that proper ore grade control is employed and that proper steps are taken to ensure that the leaching operations are executed as planned. The mining contracts for the mines include clauses addressing these issues to help ensure planned requirements are met. Nevertheless, unforeseen difficulties may occur in planned operations.

We may be adversely affected by fluctuations in molybdenum, copper, silver, gold and other metal prices.

The value and price of our common shares, our financial results, and our exploration, development and mining, if any, activities may be significantly adversely affected by declines in the price of molybdenum, copper, silver, gold and other metals. Mineral prices fluctuate widely and are affected by numerous factors beyond our control such

Augusta Resource Corporation – Annual Information Form Page 30


as interest rates, exchange rates, inflation or deflation, fluctuation in the value of the United States dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of mineral producing countries throughout the world. The price for gold fluctuates in response to many factors beyond anyone’s ability to predict. The prices used in making the resource estimates are disclosed and differ from daily prices quoted in the news media. The percentage change in the price of a metal cannot be directly related to the estimated resource quantities, which are affected by a number of additional factors. For example, a 10 percent change in price may have little impact on the estimated resource quantities and affect only the resultant positive cash flow, or it may result in a significant change in the amount of resources. Because mining occurs over a number of years, it may be prudent to continue mining for some periods during which cash flows are temporarily negative for a variety of reasons including a belief that the low price is temporary and/or the greater expense incurred in closing a property permanently.

Mineralized material calculations and life-of-mine plans using significantly lower metal prices could result in material write-downs of our investments in mining properties and increased amortization, reclamation and closure charges.

In addition to adversely affecting our mineralized material estimates and its financial condition, declining metal prices can impact operations by requiring a reassessment of the commercial feasibility of a particular project. Such a reassessment may be the result of a management decision related to a particular project. Even if the project is ultimately determined to be economically viable, the need to conduct such a reassessment may cause substantial delays in development or may interrupt operations, if any, until the reassessment can be completed.

Title to our properties may be subject to other claims.

Although we believe we have exercised the commercially reasonable due diligence with respect to determining title to properties we own, control or have the right to acquire by option, there is no guarantee that title to such properties will not be challenged or impugned. Our mineral property interests may be subject to prior unrecorded agreements or transfers or native land claims and title may be affected by undetected defects. There may be valid challenges to the title of our properties which, if successful, could impair development and/or operations. In addition, a portion of our property is leased and may be subject to defects in title, particularly due to the large number of transfers.

Estimates of mineralized materials are subject to geologic uncertainty and inherent sample variability.

Although the estimated resources at our properties have been delineated with appropriately spaced drilling, there is inherent variability between duplicate samples taken adjacent to each other and between sampling points that cannot be reasonably eliminated. There also may be unknown geologic details that have not been identified or correctly appreciated at the current level of delineation. This results in uncertainties that cannot be reasonably eliminated from the estimation process. Some of the resulting variances can have a positive effect and others can have a negative effect on mining and processing operations. Acceptance of these uncertainties is part of any mining operation.

Mineral resources are only estimates which may be unreliable.

Although the mineralized material figures included in this prospectus have been carefully prepared by independent engineers, these amounts are estimates only, and we cannot be certain that any specified level of recovery of molybdenum, copper, silver, gold or other mineral from mineralized material will in fact be realized or that any of our properties or any other identified mineral deposit will ever qualify as a commercially mineable (or viable) ore body that can be economically exploited. Mineralized material, which is not mineral reserves, does not have demonstrated economic viability. Any material change in the quantity of mineralization, grade or stripping ratio, or mineral prices may affect the economic viability of our properties. In addition, we cannot be certain that metal

Augusta Resource Corporation – Annual Information Form Page 31


recoveries in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. Until an unmined deposit is actually mined and processed the quantity of mineral resources and reserves, if any, and grades must be considered as estimates only.

Government regulation may adversely affect our business and planned operations.

We believe our exploration projects currently comply with existing environmental and mining laws and regulations affecting its operations. Our mining, processing, development and mineral exploration activities, if any, are subject to various laws governing prospecting, mining, development, production, taxes, labor standards and occupational health, mine safety, toxic substances, land use, water use, land claims of local people and other matters. We cannot assure you that new rules and regulations will not be enacted or that existing rules and regulations will not be applied in a manner which could limit or curtail production or development. At present, there is no royalty payable to the United States on production from unpatented mining claims, although legislative attempts to impose a royalty have occurred in recent years. Amendments to current laws and regulations governing operations and activities of mining and milling or more stringent implementation thereof could have a material adverse impact on our business and financial condition.

Amendments to current laws, regulations and permits governing operations and activities of mining and exploration companies, or more stringent implementation thereof, could have a material adverse impact on our business and cause increases in exploration expenses, capital expenditures or production costs or reduction in levels of production at producing properties or require abandonment or delays in development of new mining properties.

Our operations are subject to environmental risks.

All phases of our operations, if any, will be subject to federal, state and local environmental regulation in the various jurisdictions in which it operates. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste. Environmental legislation is evolving in a manner which will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors and employees. We cannot be certain that future changes in environmental regulation, if any, will not adversely affect our operations, if any. Environmental hazards may exist on the properties on which we hold and will hold interests which are unknown to us at present and which have been caused by previous or existing owners or operators of the properties.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or remedial actions. Parties engaged in mining operations or in the exploration or development of mineral properties may be required to compensate those suffering loss or damage by reason of the mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations.

Production, if any, at our mines will involve the use of hazardous materials. Should these materials leak or otherwise be discharged from their containment systems then we may become subject to liability for hazards that it may not be insured against or for clean up work that may not be insured.

We do not insure against all risks.

Our insurance will not cover all the potential risks associated with a mining company’s operations. We may also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage may

Augusta Resource Corporation – Annual Information Form Page 32


not continue to be available or may not be adequate to cover any resulting liability. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to us or to other companies in the mining industry on acceptable terms. We might also become subject to liability for pollution or other hazards which may not be insured against or which we may elect not to insure against because of premium costs or other reasons. Losses from these events may cause us to incur significant costs that could have a material adverse effect upon its financial condition and results of operations.

We compete with larger, better capitalized competitors in the mining industry.

The mining industry is competitive in all of its phases. We face strong competition from other mining companies in connection with the acquisition of properties producing, or capable of producing, base and precious metals. Many of these companies have greater financial resources, operational experience and technical capabilities than us. As a result of this competition, we may be unable to maintain or acquire attractive mining properties on terms it considers acceptable or at all. Consequently, our revenues, operations and financial condition could be materially adversely affected.

We are dependent on our key personnel.

Our success depends on our key executives: Richard Warke, Chairman, Gil Clausen, President, Donald Clark, Chief Financial Officer, Mike Clarke, Vice President Exploration and James Sturgess, Vice President Projects and Environment. The loss of the services of one or more of such key management personnel could have a material adverse effect on the Company. Our ability to manage its exploration and development activities, and hence our success, will depend in large part on the efforts of these individuals. We face intense competition for qualified personnel, and we cannot be certain that we will be able to attract and retain such personnel.

Our officers and directors may have potential conflicts of interest

Our directors and officers may serve as directors and/or officers of other public and private companies and devote a portion of their time to manage other business interests. This may result in certain conflicts of interest. To the extent that such other companies may participate in ventures in which we are also participating, such directors and officers may have a conflict of interest in negotiating and reaching an agreement with respect to the extent of each company’s participation. The laws of Canada require the directors and officers to act honestly, in good faith, and in the best interests of the Company and its shareholders. However, in conflict of interest situations, our directors and officers may owe the same duty to another company and will need to balance the competing obligations and liabilities of their actions. There is no assurance that our needs will receive priority in all cases. From time to time, several companies may participate together in the acquisition, exploration and development of natural resource properties, thereby allowing these companies to: (i) participate in larger programs; (ii) acquire an interest in a greater number of programs; and (iii) reduce their financial exposure with respect to any one program. A particular company may assign, at its cost, all or a portion of its interests in a particular program to another affiliated company due to the financial position of the company making the assignment. In determining whether or not we will participate in a particular program and the interest therein to be acquired by it, it is expected that our directors will primarily consider the degree of risk to which the Company may be exposed and its financial position at the time.

We provide indemnity and protection to our directors and officers

Section 7 of our By-Law No.1 states in part that:

The Company shall indemnify a director or officer, a former director or officer, or a person who acts or acted at the Company’s request as a director or officer of a body corporate of which the Company is or was a shareholder or creditor... against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment . . ..”

Augusta Resource Corporation – Annual Information Form Page 33


Thus, we may be required to pay amounts to settle any such claims that may arise. The impact of any such possible future indemnity protection cannot be determined at this time.

Our stock price is subject to volatility

During the year ended December 31, 2005, our share price ranged from $0.37 to $3.92 per share. The market price of a publicly traded stock, especially a junior resource issuer like us, is affected by many variables not directly related to our exploration success, including the market for junior resource stocks, the strength of the economy generally, the availability and attractiveness of alternative investments, and the breadth of the public market for the stock. The effect of these and other factors on the market price of the common shares on the stock exchanges on which the Company trade, suggest the Company's shares will continue to be volatile.
