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 total cost of the mining concession, mine development costs, land, buildings and other facilities, machinery and equipment, furniture and fixtures, transportation units, computer equipment and tools, quarry rehabilitation costs, capitalized interest and work in progress amounts to as of December 31, 2021.
 
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.

10.4 Opinion of Qualified Person on Adequacy of Test Data
 
The QP, as part of Loma Negra’s geologist team, is satisfied with the preparation, review, issuance and control of test reports associated with cement production, and considers them to be reasonably valid. The QP’s opinion is that the test data that underlies assumptions about cement production in the associated test reports has been analyzed and collected appropriately and reasonably and is adequate to support the assumptions in this technical report.

Draft disclosure in response to comment 7.

10.2.Cement Manufacturing Test Results
 
The studies conducted in the Quality Control and Process area include reduction of the clinker/cement factor. The clinker/cement factor cements were 0.87 in 2021 (mostly influenced for the OPC cement type production) for L'Amali plant. In the case of Olavarría Plantplant, the factor in 2021 was 0.63. In the case of both L'Amali plant and Olavarría plant, due to the characteristics of the process, the rate of metallurgical recovery is 100%.

12.3.2 Reasonable Prospects of Economic Extraction

The mineral reserves evaluation has considered other modifying factors such as limestone production costs, cement sales prices, environmental and social viability at our operations. The price assumed for the mineral reserves evaluation is a price of 93 US dollars per ton of cement, averaged over a 63-year projection for the life of the quarry, at nominal values.

Draft disclosure in response to comment 8.

13.6 Life of Mine
 
A LOM (life of mine (“LOM”) of 134 years has been calculated for the quarry, based on the exploitation of the last five years (average 4.69 million tonnes per year). Considering the maximum capacity of the three plants supplied by the quarry (9.39 million tonnes per year), LOM would be 63 years.

Draft disclosure in response to comment 9.

Cement prices are strongly correlated with inflation and the variation in the exchange rate between the Argentine peso and the US dollar, as reflected by historical data for the five years.

Draft disclosure in response to comment 10.

Considering that the quarry production and cement plants will continue in the same geological deposit and using the same mining and industrial methods, there is limited risk associated with the estimation methods used for capital and production costs. An assessment of accuracy of estimation methods is reflected in the sensitivity analysis in Section 19. Forecasted capital and operating costs are estimated to an accuracy of +/- 25% with a contingency of 5%.

Draft disclosure in response to comment 11.

19.2 Economic Viability

Loma Negra has positive cash flow and La Pampita y Entorno quarry does not require a significant capital expenditure in the near future, therefore, payback and return on investment calculations are irrelevant. NPV was calculated using L’Amalí´s and Olavarría’s figures as the limestone obteind in La Pampita y Entorno quarry is exclusively used in the production of cement and lime. The NPV is US$597 million. The forecast horizon is considered to be consistent with the quarry’s life (63 years), which is calculated based on the total declared Reserves and the annual production of the quarry.
