Overview of Mining Properties and Operations

Our cement operations are supplied by limestone reserves that are located within close proximity to our production facilities. We own and operate six open-pit quarries from which limestone can be extracted efficiently due to the proximity of the limestone deposits to the surface and the quality of the limestone in the mines that meets the process requirements.

Each of our plants possesses and is responsible for several active and inactive mining licenses. Active mining licenses are those for which we hold all necessary permits and rights to actively exploit the mineral mass. Each of our plants also holds inactive mining licenses on areas for which we do not have the operational license, since their exploitation is not currently necessary.

Individual Properties Disclosure

La Pampita y Entorno

Location and History

The La Pampita y Entorno quarry extends over the mining operations of La Pampita, Don Gabino, Los Abriles, and San Alfredo Sur II, which are located in the district of Olavarría, Buenos Aires province. The quarry is located 20 kilometers to the southeast of the city of Olavarría, near the town of Villa Alfredo Fortabat. The region is generally characterized by nonmetal mining activity, including cement as well as aggregates and ceramics.

The mining operations are carried out on land owned by Loma Negra since 1980. Exploration activity began in that year and has since been conducted discontinuously to date. Explotation of the La Pampita mining property began in 1999. The San Alfredo Sur II, Los Abriles and Don Gabino mining properties are currently inactive and do not register any mining activities (i.e., they are entirely exploratory projects). In 2021, we did not conduct any exploration activity at the La Pampita y Entorno quarry.

Our L’Amalí and Olavarría cement plant and La Pampita y Entorno mining operations are shown in the maps below.

Infrastructure and Personnel

The La Pampita y Entorno quarry has the necessary infrastructure for normal operations. Facilities for electric power, water supply, fuels, accesses, and roads have been installed.

La Pampita y Entorno has two primary ThyssenKrupp crushers. One sends limestone to L’Amalí plant through conveyor belts for further storage in two preheaters. The other primary crusher sends material to the lime factory or to the secondary crusher.

In the quarry, electrical energy is supplied through a 33 Kv line coming from the L’Amalí plant, and the plant is externally fed by a 132 KV line. There are seven electrical substations in the quarry.

The fuel used for operational purposes is supplied to the contractor by a subcontractor.

The water extracted from the quarry is used for irrigation, dust suppression sprinkler systems in crushers and belts, quarry services (buildings and restrooms) and for 100% of the water supply to the L’Amalí plant.

6

Loma Negra’s personnel conducts its operations at La Pampita quarry with its own staff and contractors, including 19 employees and 113 outsourced staff from both contractors.

The majority of the La Pampita y Entorno quarry’s personnel comes from the town of Olavarría, adjacent to the quarry. There are also personnel from other regions of Argentina.

Personnel are transported from the town of Olavarría to the quarry in buses and pickup trucks.

Mining Concession Ownership and Area

The mining producer registration (RPM) was granted by Resolution EX-2020-15636796-GDEBA-DPGMMPCEITGP of the Undersecretary of Mining of Buenos Aires Province.

The procedure to obtain a mining concession is established in Argentina’s Mining Code (as described below).

We have the surface rights of the operation area in the La Pampita y Entorno quarry.

Royalties

The main statute that governs mining in Argentina is the Mining Code, which was enacted nationwide by Law No. 1,919 of 1886, as amended.

We pay the mining canon for each concession. These payments must be made twice a year. Payment is equivalent to US$0.3 per hectare.

The payment is made through regular banking channels.

In case the mining royalty is not declared or paid, penalties for infractions and default interest for non-compliance are incurred. However, failure to pay these fines is not a cause for the loss of the mining concession.

We also pay a quarry exploitation fee. Municipalities establish certain taxes that may have incidence on mining developments. Each jurisdiction in which mining activities are developed has its legislation.

For example, municipalities may charge a quarry exploitation quota equivalent to the amount of limestone contained in the cement dispatched or sold from the factory at a rate determined by each municipality. The rate is determined at a fixed amount, which is updated on a monthly basis. This amount represented 1.4% of sales in 2021 of cement, masonry cement and lime.

Set forth below is additional information relevant to this property.

Mining Activities

The mining method is open pit mining, which consists of mining in a series of benches with pit expansion possible both vertically and laterally. The quarry generally proceeds top-down with a height of 10 meters. The materials are loaded by loaders and transported to the primary crusher or waste dump by dump trucks.

The diagram below sets forth the block diagram of mining process of the La Pampita y Entorno quarry. Further details of the process are provided in the TRS, a copy of which is filed as Exhibit 96.1 to this annual report.

Cement Plants

Our L’Amalí and Olavarría plants have been in operation for 21 and 96 years, respectively, and both use the limestone extracted from the La Pampita quarry in the manufacture of cement and lime.

Our L’Amalí and Olavarría plants are located in Olavarría area. These plants are 2 and 5 kilometers, respectively, from the La Pampita y Entorno quarry and receive raw materials from the La Pampita y Entorno quarry.

Our plants produce various products for the construction industry, the main product being cement. Different types of cement are produced depending on their applications, using limestone, iron ore and clays as raw materials. Our Olavarría plant also produces lime as a product, using limestone as a raw material.

The below figure shows the flow of cement production at the L’Amalí and Olavarría plants.

We believe that the equipment in operation at our L’Amalí and Olavarría plants is in optimal condition to avoid any interruption in cement and lime production. Maintenance and optimization of the equipment is carried out periodically and is supervised by our personnel. The equipment is in good condition and operational. Further details of the equipment are provided in the TRS, a copy of which is filed as Exhibit 96.1 to this annual report.

Our L’Amalí and Olavarría plants have facilities such as maintenance workshops, warehouses, laboratories, administrative offices, and cement and lime production lines that support production.

La Pampita y Entorno Quarry

The La Pampita y Entorno quarry have been operating for 22 years. The material extracted from the quarry is exclusively used to supply our plants. The amount of limestone to be mined is planned annually as part of our overall mining plan.

We believe that the equipment in operation at the La Pampita y Entorno quarry are in optimum condition to maintain continuity of operations. Maintenance and optimization of the equipment is carried out periodically and is supervised by the operator of the quarry. The equipment is in good condition and operational. Further details of the equipment are provided in the TRS, a copy of which is filed as Exhibit 96.1 to this annual report.

Facilities

The La Pampita y Entorno quarry has facilities such as offices, an electrical substation, a maintenance shop, a lubricant warehouse, a gas station, a oil tank, a guardhouse, a limestone field, a dining room, a laboratory, a truck scale, an ore belt, a loading tunnel, a meteorological station, a safety trench and a septic tank.

The book value of L’Amalí and Olavarría cement plants and the La Pampita y Entorno quarry, taking into account all of the above factors, amounts to Ps. 59,186.85 million as of December 31, 2021.

Property Encumbrances

We do not make any payments with respect to any significant encumbrances for the L’Amalí and Olavarría plants, and the La Pampita y Entorno property. The La Pampita y Entorno mining operations currently have no outstanding payments with respect to infractions and penalties.

Geology

The La Pampita y Entorno quarry is located in the Tandilia System, a mountain belt which is geomorphologically composed of three main groups of small hill ranges surrounded by plains. The basement of the Tandilia System is made up of granitic complexes and sedimentary rocks of various ages. Calcareous formations are useful materials for the conformation of the raw material used in the cement industry. The contributions of CaCO3 from the calcareous levels allow a mining process suitable for the industry.

Total mineral reserves		626.7		11.29		1.57		0.86		47.38		139.11

Note: All reserves are estimated as quantities at cement plant.

For evaluation purposes, information from exploration activities from previous years has been used and is the database for the reserves model.

The reserve estimation considered the quality restrictions of limestone received in L’Amalí and Olavarría cement plants, accessibility to the reserves, economic factors and modifying factors.

A life of mine of 134 years has been calculated for the quarry, based on the exploitation of the last five years. Considering the maximum capacity of the plants supplied by the quarry, the life of mine would be 63 years.

The following table includes a reconciliation of reserves at the end of the last two fiscal years.

Reserves for the Last Two Fiscal Years Expressed in Millions of Tonnes*

The per-ton price assumed for the Mineral Reserves estimation in the economic model can be found in the TRS, a copy of which is set forth in Exhibit 96.1 to this annual report. All reserves are estimated at cement plant. The average price is 93 US dollars per ton of cement, average of the 63-year projection, at nominal values.

Development of the Property Activities

Not applicable.

Internal Controls for Reserves Disclosures

We have implemented controls and procedures designed for quality assurance and quality control on the Company’s production activities and associated information for the estimation of mineral resources and reserves.

The quality assurance and quality control measures are applied to quarry production and cement plant processing activities. We apply industry standards to evaluate the reliability of laboratory results that analyze exploration samples used in calculating mineral reserve estimates, which are then analyzed and verified annually by other business units within the Company. Internal personnel also verify the data resulting from analysis prior to using it in their work.

Additionally, we have implemented internal controls designed to ensure its mineral resources and reserves estimates are compliant with Regulation S-K Item 1300 requirements, including the preparation of reserve estimates by “qualified persons” and others on the matter in the different locations where we operate. Specifically with respect to the La Pampita y Entorno mining operations, further details (including with respect to quality control) can be found in the TRS, a copy of which is set forth in Exhibit 96.1 to this annual report.

PART II

ITEM 15. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our CEO and CFO, has evaluated the effectiveness of our disclosure controls and procedures, as that term is defined under Rules 13a-15(e) and 15d-15(e) of the Exchange Act, as amended, as of December 31, 2021. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. We performed an evaluation of the effectiveness of our disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file with or submit to the SEC under the Exchange Act, as amended, is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and is communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding the required disclosure. Based upon our evaluations, our CEO and CFO have concluded that our disclosure controls and procedures were, as of December 31, 2021, not effective to provide reasonable assurance of their reliability, solely in relation to certain required disclosures under Item 1300 of Regulation S-K.

We have filed this Amendment No. 2 to include the disclosures required to comply with Item 1300 of Regulation S-K and file the related technical report. Our management began improving in 2022, and continues to improve, our disclosure controls and procedures to remediate the deficiency that led our CEO and CFO to conclude that such controls and procedures were, as of December 31, 2021, not effective to provide reasonable assurance of their reliability. As of the date of this Amendment No. 2, our management, including our CEO and CFO, believes that the actions already undertaken have fully remediated the deficiency, and include: (i) additional training of our financial reporting and legal personnel on the application of Regulation S-K 1300; (ii) enhanced communication and collaboration between our financial reporting and legal personnel, an individual at our Company who is a “qualified person” as defined in Regulation S-K 1300 and other of our personnel with respect to the preparation of Regulation S-K 1300 disclosures and the related technical report included in this Amendment No. 2; and (iii) the preparation of a plan for our compliance with Regulation S-K 1300 to the extent applicable in future years, including annual testing on the materiality of our mineral reserves (and, to the extent important to the business, mineral resources) and a timeline for recording, processing, summarizing and reporting data by the teams mentioned in (ii) in line with Regulation S-K 1300 to the extent applicable. We will also test the ongoing operating effectiveness of these new and existing controls in future years.
