1.Executive Summary

 

Cementos Selva S.A.C. (CSSAC), a wholly-owned subsidiary of Cementos Pacasmayo S. A.A., is a Peruvian company whose corporate purpose is the production of cement and other products associated with the construction sector. This Technical Report Summary summarizes the Pre-feasibility study of the Tioyacu quarry located in the San Martin Region and the Rioja plant located in the same region, both owned by CSAAC. Qualified professionals from Cementos Pacasmayo have prepared the report to support the Resources and Reserves Estimates.

 

1.1.Location and access

 

The Tioyacu quarry contains limestone, a non-metallic mineral that is primarily used as raw material in cement production. This quarry is located in the district of Elías Soplin Vargas, Rioja Province, San Martin Region. The access route to this quarry is by land through the Fernando Belaunde Terry highway. The cement plant located in the city of Rioja is adjacent to the Tioyacu quarry.

 

1.2.Climate

 

The vegetation is evergreen with lianas and vines, many of which are covered by epiphytes of the Bromeliaceae family. The forests have a very heterogeneous floristic composition.

 

The climate in this Amazon region in northern Peru is mainly influenced by the following factors: the Intertropical Convergence Zone (ITCZ), the presence of the Eastern Cordillera of the Andes and the Extratropical Fronts.

 

1.3.History

 

On February 6, 1998, the public auction of the Rioja Cement Plant was held, and Consorcio Pacasmayo was awarded the contract. To comply with the terms of the auction, Consorcio incorporated and subsequently transferred ownership of the plant to Cementos Rioja S.A. The award mentioned above included, by public deed dated April 8, 1998, the non-metallic mining concession “Calizas Tioyacu.” The Tioyacu quarry began operations as Cementos Rioja S.A. in 2000.

As historical information about the quarry, a campaign of 460 meters of drilling was carried out in 05 drill holes located in the eastern flank of the “Tioyacu” limestone-dolomitic massif executed by the company Andes Diamantina S.R.L., at the end of 1982 into early 1983. The objective was to determine the feasibility of a new portland cement plant in the region of San Martin. The exploration study identified significant limestone material suitable for cement manufacturing.

 

In 2015, Cementos Selva S.A. commissioned Geosym Consultores S.A.C. to carry out prospecting work through drilling. A total of 06 mixed drill holes were drilled, conveniently located and distributed along the Tioyacu quarry: 02 drill holes in the southern sector, 03 drill holes in the central area, and 01 drill hole in the northern sector, to geologically evaluate the deposit and know its conditions at depth. These 06 drillings carried out in the campaign in conjunction with blast hole information and geological evaluation work allowed the inventory of Mineral Resources and Reserves to be updated.

 

From 2018 to the present, Cementos Selva S.A., with the help and support of mining software such as Leapfrog and Minesight has developed the updated estimates of its Resources and Reserves at the Tioyacu quarry.

 

On March 1, 2022, Cementos Selva S.A. changed its corporate name to Cementos Selva S.A.C. (CSSAC).

 

From October to November, 2023, the Rioja plant stop its operations because there was general power outage in the area.

 

In December 2023, Cementos Selva started a diamond drilling campaign of 6 drill holes to confirm Resources and Reserves.

 

1.4. Geological environment and mineralization

 

The strata of the district of Elias Soplin Vargas, province of Rioja, San Martin region consists of Paleozoic/Mesozoic Age sedimentary formations of the Mitu Group, Pucara Group, Chambara Formation, Celendín Formation, Aramachay Formation, Condorsinga Formation, Ipururo Formation, and Quaternary Deposits.

1.5.Exploration

 

Cementos Selva S.A.C. did not carry out any exploration activities at the Tioyacu quarry during the current year. The exploration activities described in section 1.3 describe the exploration work at the Tioyacu quarry till date.

 

During 2023, Cementos Selva performed a drilling campaign in the Tioyacu quarry in order to estimate Reserves, the drilling activities will continue during the 2024.

 

1.6.Preparation of samples, analysis and security

 

Cementos Selva S.A.C. has implemented international standards in all its operations such as quarries and plants. The ISO 9001 standards has been implemented and certified since 2015. The certification is renewed annually through an external audit.

 

The SSOMASIG (Security, Occupational Health, Environment and Management Systems) department, is part of the team that determines and gives the necessary support for the maintenance of the ISO 9001 and the scope is in all the company’s activities.

 

Cementos Selva S.A.C. has implemented QaQc protocols to develop exploration and production activities in the Tioyacu quarry and Rioja plant to ensure the quality of the information used for estimation of limestone Resources and Reserves.

 

With respect to the geology, CSSAC uses the XRF technique and other analytical methods to analyze the main chemical components in the limestone. In the cement plant, the raw materials for the production of clinker and cement are analyzed using methods specified in the A.S.T.M. and Peruvian Technical Standards for cement testing. The laboratory in the cement plant has properly calibrated equipment and a periodic maintenance plan.

 

On the other hand, the Rioja plant, through its Quality Assurance and Control area, has implemented a sampling and data verification plan, which applies to the processes of receiving minerals, crushing of materials, drying of raw materials, grinding of crude, clinkerization, grinding of cement and cement packaging

1.7.Data verification

 

CSSAC Concerning geological activities, CPSAA has a data verification department for the geological database. This deparment has as its main function, the verification of data to be used in the estimation of Mineral Resources and Reserves. For the appropriate administration of information, internal protocols have been implemented that are subject to internal audits. The stages within the verification activities for the geologic data are the data collection, the administration and validation of data received from internal and external laboratories, data tracking through the confirmation of custody chains and finally, validation of data in the database that will allow the development of the Mineral Resources and Reserves model.

 

For data verification activities at the cement plant, the Plan, Do, Check and Act (PDCA) methodology is used. This is applied to the technical information received from the company’s internal and external customers. The quality control laboratory compares the results with national and international laboratories as part of the verification procedures.

 

1.8.Mineral processing and metallurgical test

 

Cementos Pacasmayo has procedures for developing products at the laboratory level and scaling at the industrial level (including at Cementos Selva S.A.C. operations). It has guidelines for preparing, reviewing, insurance, and controlling laboratory test reports. Cemento Pacasmayo has a research and development laboratory located in the Pacasmayo plant to evaluate the technical aspects of cement plants and quarry operations.

 

At the Pacasmayo plant, the studies conducted in the Research and Development laboratory and the Quality Control area include the substitution of fossil fuels for rice husks at the Rioja plant.

 

The main objective of the substitution of fossil fuels is the reduction of CO2 or greenhouse gas emissions.

 

In 2023, CSSAC used 4,645 t of Alternative Fuel (measured as coal equivalent) in the Rioja plant. This result represented 10.82% of the total fuels used by the plant for cement production and a reduction in emissions of 12,194 t of CO2.

A significant percentage of Research and Development activities are focused on evaluating different ratios between clinker-mineral additions providing the best functional characteristics to our products and at the same time balancing the benefits generated for the company. Another objective is to identify other additions that can substitute for clinker: slag, pozzolana, fly ash, calcined clays, etc., to reduce its environmental footprint and the cost of cement production. Based on this work, the laboratory has determined (and confirmed with production estimates) that 1 tonne of limestone yields 0.79 tonnes of clinker and the clinker/cement factor of the main cements with additions is 0.72.

 

The Research Laboratory issues technical reports following the criteria of international standards to the operations area, which evaluates the convenience of implementing the tests industrially and validating what is reported at the laboratory level.

 

1.9.Mineral Resources and Reserves

 

Cementos Pacasmayo’s QPs have developed the estimation of limestone Resources and Reserves. For the evaluation, information from exploration activities carried out until 2023 has been used.

 

The limestone Resources are presented in Table 1. The result of the estimation of Resources considered the quality restrictions of limestone received at Rioja plant, accessibility to the Resources and legal limits inherent to the mining concessions, relevant economic and technical factors.

 

The minimum quality accepted is 49% CaO to be used as raw material for production. Considering the selling prices of cement at the Rioja plant, the economic evaluation used for the estimates of Resources and Reserves is shown in Chapter 19.

 

Table 1 Mineral Resources (exclusive of Reserves) of Tioyacu quarry

 

  Resources Tonnes M CaO (%) Al2O3 (%) MgO (%) SiO2 (%) K2O (%)
Limestone Measured 0.05 50.10 0.60 1.01 5.82 0.22

1.11.Processing Plant and Infrastructure

 

Cement production considers the stages of raw material extraction, grinding, homogenization, clinkerization, cement grinding, silo storage and packaging, loading, and transportation. Cement is moved through conveyor belts to bagging systems to be packed in bags and then loaded onto trucks operated by third parties for distribution.

 

The raw materials for cement production are Limestone, Sand, Iron, Clay, Coal. The mixture of these raw materials is crude and is fed to the calcination kiln to produce clinker.

 

Limestone represents 73.26% by weight of the crude. Anthracite coal is also used as part of the raw material for the production of clinker. Clinker and additions are used to produce cement. The additions used in cement production are slag, pozzolana, and gypsum. Currently, the cement plant in Rioja has a clinker/cement factor of 0.76.

 

The Rioja plant has an electrical substation with a capacity of 12 MVA. Rioja plant uses electric power, which is supplied from the national grid.

 

Cementos Selva has implemented a preventive and corrective maintenance plan for equipment to prevent interruptions to cement production. Additionally, operating efficiency controls costs and operating margins.

 

1.12.Market studies

1.13.Capital, Operating costs and Economic Analysis

 

This document presents the cash flow analysis and an economic evaluation of the project based on the current operating costs of the Rioja plant and using information on the Tioyacu quarry for limestone production.

 

For the Reserves evaluation, the general and macroeconomic assumptions used for the projection of the free/economic cash flows and for the valuation are:

 

Projection horizon: 24 years (2024 to 2047) according to the estimated years of quarry life.

 

The annual escalatioin rate; 2.90%, based on based on The International Monetary Fund as of October 2023: applies equally to the sales price, costs, and expenses.

 

Capital cost projections were determined using a historical ratio of annual investments and maintenance costs, which also considers the increase in production volume.

 

The company’s financing structure is being considered in the discount rate (WACC), which is 11.56%, not in the cash flows.

 

Income tax rate: effective rate of actual (historical) business results, 29% - 30%.

 

Workers’ Profit Sharing: 10%.

 

Exchange rate: exchange rate is assumed to remain at 3.80 (USD/PEN).

 

The economic analysis considers the same evaluation criteria for estimating Resources and Reserves, considering that the Tioyacu quarry is one location using the same infrastructure and mining methods. The main variables considered in the economic model for the sensitivity analysis were cement price, production cost, and Capex.

 

The free cash flow is constructed for the economic analysis, which does not incorporate the financing structure. The latter is considered in the weighted average cost of capital of the company (WACC) to discount future cash flows. The following financial parameters were calculated:

 

24-year mine life

 

Average plant throughput of 0.4 million tonnes per year over the 24-year projection.

 

9

 

 

Average sales price of 724.6 soles per ton of cement, on average for the 24-year projection, at nominal values.

 

Revenues of 275 million soles, on average for the 24-year projection.

 

Average cash production cost of 469.4 soles per ton of cement, on average for the 24-year projection, at nominal values.

 

The cash flow of the project is presented in Table 3 below. The NPV at a discount rate of 11.56%, is 363 million soles.

1.15.Conclusions

 

From a legal point of view, Cementos Selva S.A.C has the ownership of the mining properties for the exploration, development and production of limestone to supply the cement plants for normal production during the life of the quarry.

 

Cementos Selva S.A.C has been complying with international ISO-9001 standards since 2015 and has implemented Quality Assurance and Quality Control (QAQC). The controls are applied for the construction of the Geological Model, Resource estimation and Reserves estimation.

 

Cementos Selva S.A.C has a quality assurance system in its operations that includes sample preparation methods, procedures, analysis and security, which comply with the best practices in the industry.

 

The information verification and validation processes are carried out following the procedures indicated in the information flows. The validated information is congruent with the one that generated the geological models, and is the fundamental basis for the estimation of Resources.

 

The geological modeling of the limestone deposit is consistent with the relationship between the information and the geological model.

 

The Reserves estimates consider the geologic and modifying factors as well as risk. The quality variable is the CaO content which is very stable in the deposit. There also are other secondary variables that determine the quality of the Reserves.

 

In the process of calculating Mineral Reserves and in the production plans of the quarry, these variables have been adequately considered in the mining plan, properly sequenced and with blending processes. There are sufficient proven and probable Mineral Reserves for the next 24 years.

 

Table 5 shows the Mineral Resources of the Tioyacu quarry. Likewise, the Mineral Reserves are shown in Table 6.

The Health, Safety and Environment department is in charge of supervising compliance with the Company’s corporate policies and the various legal requirements of the national regulatory bodies by all company áreas.

 

Through its Social Responsibility area, Cementos Selva S.A.C has generated relationships of trust with the communities surrounding its operations. We have a solid relationship with their communities, which includes identifying their primary needs in health, education, urban development, and local development.

 

The operation in Tioyacu quarry and Rioja plant, with respect to infrastructure, is technically and economically feasible due to the life of the quarry.

 

The sensitivity analysis shows that the operation is economically robust.

1.16.Recommendations

 

Maintain the QAQC program for exploration, development and production activities associated with cement production.

 

Include QAQC plans and density control for the subsequent diamond drilling campaigns.

 

It is recommended to finish the drilling campaign that began in 2023 and carry out the geological interpretation of the data generated during the campaign, so that it can be incorporated into the Resource and Reserve model, which will provide greater support and robustness to these model.

 

Implement the Geotechnical Monitoring Plan of the quqrry componets with the installation of slope displacement control lamdmarks.

 

Maintain a permanent monitoring of the installed piezometers both for water levels and water quality, to evaluate the evolution of levels during the production of the Tioyacu quarry.

 

It is recommended that a geophysical study using the Georadar method to identify karst cavities within the quarry area be conducted, especially in areas of structural anomalies.

4.Accesibility, climate, local resources, infrastructure and physiography

 

4.1.Tioyacu quarry and Rioja plant

 

Cementos Selva S.A.C. is an industrial company dedicated to the production of cement. Its Tioyacu quarry provides limestone as raw material for cement production.

 

The Tioyacu quarry is geographically located in the district of Elías Soplín Vargas, province of Rioja, department of San Martín, approximately 14.46 km from the city of Rioja.

 

Topography

 

The study area consists mainly of hillsides with slopes ranging from 25% to more than 75%, terraces of alluvial origin, with slopes of less than 8% and slightly undulating, and small hillsides. The Tioyacu quarry has an average altitude of 900 meters above sea level.

 

Vegetation

 

The vegetation is evergreen with lianas and vines, many of which are covered by epiphytes of the Bromeliaceae family. The forests present a very heterogeneous flora composition.

 

Access

 

By air is from Lima – Tarapoto in a 1.5 hour flight, and by land from Tarapoto to Tioyacu quarry for a journey of 3 hours.

 

Access to the Tioyacu quarry is via the Fernando Belaunde Terry highway, which crosses the district of Elías Soplin Vargas from south to north.

 

24

 

 

Climate

 

The climate in this Amazon region in northern Peru is mainly influenced by the following factors: the Intertropical Convergence Zone (ITCZ), the presence of the Eastern Cordillera of the Andes and the Extratropical Fronts.

 

Physiography

 

The study area has landforms that have been generally classified as large plains landscape and mountainous landscape (mountain slopes).

 

Local Resources

 

The Tioyacu quarry is operated by Cementos Selva S.A.C personnel. The quarry is located 13.7 kilometers from the town of Rioja, which has the resources of a city.

 

Power is supplied by the 60 kV Rioja - Nueva Cajamarca transmission line owned by Electro Oriente.

 

The company has a water use license for industrial purposes, with its water catchment point located in the Tioyacu River. The National Water Authority issued the authorization R.A. Nº 100-2010-ANA-ALA ALTOMAYO.

 

25

 

 

5.History

 

On February 6, 1998, the public auction of the Rioja plant was held, and Consorcio Pacasmayo was awarded the contract. To comply with the terms of the auction, Consorcio incorporated and subsequently transferred ownership of the plant to Cementos Rioja S.A. The award mentioned above included, by public deed dated April 8, 1998, the non-metallic mining concession “Calizas Tioyacu.” The Tioyacu quarry began operations as Cementos Rioja S.A. in 2000.

 

At the end of 1982 and beginning of 1983 a campaign of 460 meters of drilling was carried out in 05 drill holes located in the eastern flank of the “Tioyacu” limestone-dolomitic massif executed by Andes Diamantina S.R.L. The objective was to determine the feasibility of a new portland cement plant in the department of San Martin. The exploration study identified limestone suitable for cement manufacturing.

 

In 2015, Cementos Selva S.A.C. commissioned Geosym Consultores S.A.C. to carry out prospecting work through drilling. A total of 06 drill holes were drilled, conveniently located and distributed along the Tioyacu quarry (02 holes in the southern sector, 03 holes in the central área, and 01 hole in the northern sector) to geologically evaluate the deposit and know its characteristics at depth.

 

These 06 drillings together with blast holes information and geological evaluation work allowed Cementos Pacasmayo to update the inventory of Mineral Resources and Reserves.

 

From 2018 to the present, Cementos Selva S.A.C., with the help and support of mining software such as Leapfrog and Minesight has updated its Resources and Reserves at the Tioyacu quarry.

 

On March 1, 2022, Cementos Selva S.A. changed its corporate name to Cementos Selva S.A.C. (CSSAC).

 

From October to November, 2023, the Rioja plant stop its operations because there was general power outage in the area. During 2023, Cementos Selva performed a drilling campaign in the Tioyacu quarry in order to confirm Reserves.

6.Geological setting, mineralization, and deposit

 

6.1.Regional geology

 

The strata of the district of Elias Soplin Vargas, province of Rioja, San Martin region consists of Paleozoic/Mesozoic Age sedimentary strata of the Mitu Group, Pucara Group, Chambara Formation, Celendín Formation, Aramachay Formation, Condorsinga Formation, Ipururo Formation, and Quaternary Deposits.

 

Figure 6 Regional stratigraphic column

 

 

 

6.2.Local geology

 

A lithological series of continental marine facies of limestones, marls, and dolomites have been identified in the quarry area. The classification of carbonate rocks based on the percentage of magnesium carbonate and clays, proposed by J.R.V Brooks (1896) and modified by J.A. Martinez-Alvarez, was used.

 

In the Tioyacu quarry, ten types of rocks were classified, corresponding to a sequence of limestones, magnesian limestones, dolomitic limestones, dolomitic marly limestones, marly limestones, marls, calcareous marls, clayey marls, dolomites, and calcareous dolomites. Overlying this formation are recent Quaternary deposits, consisting mainly of alluvial deposits comprised of colluvium and terraces with blocks and gravels in a sandy clay matrix.

Incorrect drillhole coordinates (including elevation).

 

Mislabeled drillhole lithology.

 

Unnoticed erroneous quality analyses where duplicate analyses were not requested.

 

Unrecorded drillhole core loss.

 

Data validation follows the field operational procedures that collect information from the source (collar, survey, lithology, samples, and assays).

 

Finally, when the information is transmitted and uploaded to the mining software for geological modeling and estimation, it is double-checked to eliminate any additional errors.

 

38

 

 

9.1.6.Qualified Person’s Opinion Geologic Data

 

The qualified persons followed the defined processes for information flows to support Resource and Reserve estimation. The qualified person followed the same process as a means of verifying and validating the geologic data. They found that the validated information is congruent in the interpretations of the same, with which the fundamental base geological models were generated for the estimation of the Resources.

 

No findings have been found that could invalidate the estimation of the Resources and Reserves of the unit.

 

9.2.Rioja plant

 

The Quality Control Plan contemplates the following aspects: PDCA cycle, customer, person in charge, activities, risks, control methods, monitoring, measurement, analysis, evaluation and documentary evidence.

 

The PDCA cycle is:

39

 

 

The data resulting from these three types of analysis are recorded and evaluated in order to determine whether or not they comply with the technical specifications.

 

Data verification procedures include internal audits, check lists, statistical tables, reports, validation of data, certificates, interlaboratory test reports and compliance with quality protocols.

 

9.2.2.Data validation

 

Cementos Pacasmayo S.A.A. (Included Cementos Selva S.A.C.) through its quality assurance and control area participates in evaluations with international laboratories such as CCRL/ASTM (Concrete and Cement Reference Laboratory), which is an international reference laboratory for construction materials, and Xamtec of Colombia, an international interlaboratory, in order to report reliable data.

 

The Quality Control laboratories endorse their analysis methods by participating in interlaboratory analysis programs, which compare the results with national and foreign laboratories. The methods of analysis compared are X-ray fluorescence (XRF) and the physical cement tests, which are the methods used to control cement quality. In all the results of these interlaboratory programs, the companies always obtain the best results for each test.

 

9.2.3.Qualified Person’s Opinion on cement plant

 

In the author’s opinion, the methodologies used for collection and processing data at the cement plant are accurate and free of significant errors. The information can be used for model construction and estimates for cement production. Considering that the analyses of the main chemical components and physical properties of the raw materials and final products are completed by external laboratories, the quality of the information is adequate for preparing Mineral Resource and Reserve estimates.

 

40

 

 

10.Mineral processing and metallurgical testing

 

10.1.Nature of Testing Program

 

Cementos Pacasmayo S.A.A. (included Cementos Selva S.A.C) has Quality Assurance, Research and Development department. The objective of these department is to develop, evaluate and research procedures for the development of products at laboratory scale and their scaling up to industrial scale. Another objective is to identify evaluations of fuel substitutes to reduce energy costs.

 

Cementos Pacasmayo S.A.A has also implemented their own procedures for the preparation, review, issuance and control of test reports associated with cement production.

 

The laboratory at Pacasmayo plant has implemented the ISO 9001 standard since 2015. The Research and Development laboratory located at the Pacasmayo plant is responsible for technical aspects of cement plant and quarriy operations (including Tioyacu quarry and Rioja Plant).

 

Cementos Pacasmayo applies the procedures:

 

-P-ID-P-04 Preparation of raw materials.

 

-P-ID-P-05 Sampling of cement and raw materials.

 

-P-ID-P-13 Input, storage and disposal of samples.

 

A permanent control is carried out with other laboratories to give greater reliability to the results. Likewise, interlaboratory reports are issued with external laboratories such as CCRL (Cement and Concrete Reference Laboratory), which is a reference laboratory for construction materials at international level, and Xamtec from Colombia, an internal interlaboratory.

 

Cementos Pacasmayo S.A.A. has also obtained the certification that certifies compliance with Supreme Decree No. 001-2022, which validates compliance with the Technical Regulation on Hydraulic Cement used in Buildings and General Construction.

 

Cementos Pacasmayo SAA opted for the highest and most rigorous certification model (Type 5) granted by ICONTEC, which has extensive experience in the certification of products and services.

 

A significant percentage of R&D activities are focused on the evaluation of alternative fuels such as rice husks. Laboratory tests are developed always seeking to generate an operational benefit for the company. Based on this work, the laboratory has determined (and confirmed with production estimates) that 1 tonne of limestone yields 0.77 tonnes of clinker and the clinker/cement factor with
additions is 0.72.

 

The R&D Laboratory located at the Pacasmayo plant provides analysis and research services to all of the company’s cement plants.

 

41

 

 

10.2.Cement Manufacturing Test Results

 

To determine the cement design, which includes the clinker/cement factor, CPSAA uses the tests outlined in national technical standards such as NTP 334.009, NTP 334.090, and NTP 334.082. The cement design is modified when some of the chemical or physical requirements present a trend that could lead to non-compliance (non-conforming product). For the clinker/cement factor, priority is given to the compressive strength test at all ages (1, 3, 7, and 28 days). If the compressive strength shows a negative trend, even modifying the operating variables to correct it, the clinker/cement factor is modified.

 

At the Pacasmayo plant, the studies conducted in the Research and Development laboratory and the Quality Control units include the substitution of fossil fuels for rice husks at the Rioja plant.

 

The main objective of the substitution of fossil fuels is the reduction of CO2 or greenhouse gas emissions.

 

In 2023, CSSAC used 4,645 t of Alternative Fuel (rice husk measured as coal equivalent) in the Rioja plant. This result represented 10.82% of the total fuels used by the plant for cement production and a reduction in emissions of 12,194 t of CO2.

 

10.3. Qualified Person’s Opinion of the Adequacy of the Test Data

 

The Research Laboratory issues technical reports following the criteria of international standards for the operations area, identifying the correct data, defining the requirements that may vary but include accuracy, consistency, and validity through an evaluation of the data and implementation of solutions, and finally, validating the adequacy of the data.

 

The operations area then evaluates the convenience of industrially implementing the tests and validating what is reported at the laboratory level.The reliability in the integrity and adequacy of The data reported by the area is based not only on the technical competencies of the collaborators but also on the high scores obtained in the external interlaboratory of recognized entities such as XAMTEC and CCRL in their different programs.

 

42

 

 

11.Mineral Resources estimates

 

The geological model was developed and structured using Leapfrog software; the solids were generated considering the quality of the lithology based on the results of the analysis of the samples taken.

 

Because the deposit is a sedimentary one, the qualified persons interpreted the geological model with the help of a set of regularly-spaced sections parallel to and perpendicular to strike of the deposit shape.

 

According to the lithological characteristics and descriptions, ten lithological horizons were recognized.

 

The lithological units have been grouped by assigning a numerical code in the mining software to simplify the modeling. Table 18 shows the lithological units with their respective numerical codes.

 

Table 18 Lithologic units of the Tioyacu quarry geological model

 

Lithologic Units Lithology Code
Limestone 1
Marly limestone 2
Magnesian limestone 3
Marly dolomitic limestone 4
Dolomitic limestone 5
Calcareous dolomite 7
Dolomite 6
Calcareous marl 8
Marl 9
Clay loam 10

 

The main criteria for geological modeling is the quality, such as the content of oxides in limestones.

 

The lithological criteria is based on the macroscopic physical characteristics of the limestone horizons and the percentage of essential elements in its composition (oxides) that determine the quality of the limestones. Based on the quality and specifications of the cement plant, the qualified persons used a cut off 51% of CaO.

 

43

 

 

Table 19 shows the referential cut-off of the oxides that determine the classification of the final limestone rock products.

The qualified persons built a block model based on the dimensions and spatial distribution of the deposits containing the material of economic interest. Table 20 shows the characteristics of the model.

 

Table 20 Characteristics of the block model

 

  Minimum (m) Maximum (m) Size (m) Number

Y 9,335,804 9,337,080 4 319
Z 720 1048 4 82

 

11.1.Database

 

A total of 341 samples from 11 drill holes were used for resource estimation. Additionally, 7,855 blast hole control samples were used to strengthen the variogram analysis of the primary variable CaO.

 

The data is managed in a database, where it is extracted and then loaded and used in MineSight software.

 

44

 

 

11.2.Density

 

For the bulk density of the rocks, diamond drilling samples were collected at the Tioyacu quarry, from which the bulk densities were determined by the wax method. The results of this determination and the bulk densities by lithological domain are shown in Table 21.

 

Table 21 Limestone density per horizon

Dolomitic limestone 2.73
Calcareous dolomite 2.70
Dolomite 2.64
Calcareous marl 2.61
Marl 2.62
Clay loam 2.10

 

11.3.Composting

 

The compositing was performed using control of the GEO Item (file 11 MS). In general, each geological unit is estimated from the information of the composites belonging to that unit. The composites should not cross “hard” boundaries between different geological units.

 

For compositing, the QPs assumed each initial core section has uniform grades in order to composite the grade profile of each borehole. During compositing, the goal was to preserve the original nature (variability) of the samples.

 

The calculated values considered in the compositing were for CaO, MgO, SO3, SiO2, Fe2O3, Al2O3, and K2O.

 

Composites were made at different lengths to determine the optimum compositing length. The 4 m composite is the size that best fits the nature of the original sample and so was used in resource estimation.

 

In addition, the modeling considered the length of the composites based on an exact multiple of the block height, which coincided with the bench height.

 

11.4. Basic statistics of the data (Assay – Composites)

 

Tables 22 and 23 show the results of the basic statistics of the elements CaO, SiO2, MgO, SO3, K2O, Na2O, and Cl for the original and composite data. The statistical analysis was done separately for each defined orebody (limestone horizon).

11.5.Extreme values

 

Extreme values are considered to be those analysis results that are not representative of the unit being studied and are defined in this work to be those that are above the mean plus twice the standard deviation.

 

In the analysis of the extreme values in the laboratory results for the calcareous lithologic units that are being estimated, no deviation has been found, all the results are coherent and representative of the levels to which they correspond.

 

11.6.Variogram Analysis

 

In the variogram analysis of the composited data, each level corresponded to a body of economic interest at the Tioyacu quarry. From the variogram analysis, it was concluded that acceptable experimental variograms could only be obtained in two lithologies due to the amount of data.

 

46

 

 

The QPs considered an experimental variogram to be acceptable if the number of pairs used to estimate the semi-variances are greater than or equal to 200. The variogram modeling consisted of fitting the experimental variograms to valid variogram models in MineSight. Of these models, the most representative was the spherical model, present in 85% of the structures, followed by the Gaussian model. Table 24 shows the results of variogram modeling.

 

Table 24 Variogram modeling parameters

 

Type of Variogram Model Spherical
Nugget effect 0.87
Total Sill 1.16
Range 82

 

11.7.Interpolation

 

The Ordinary Kriging Interpolation (OK) method was used for the primary CaO variable, Inverse of the Distance (ID2) for the secondary variables, and Nearest Neighbor (NN) for validations. Table 25 shows the main parameters used to determine the interpolations of the primary CaO variable of the Limestone and Magnesian Limestone horizons.

 

-The interpolations were performed in two consecutive passes.

 

-The first with a search radius of twice the variogram range.

 

-The second with a search radius equal to the range.

 

During interpolation, a mínimum of two and a maximum of 20 composites were used to estimate block qualities. Additionally, the QPs restricted the interpolation to using a maximum of two composites from each drill hole in all the passes.

11.8.Resources estimation

 

Mineral Resource estimates are effective December 31, 2023. All Mineral Resources are estimated as quantities at cement plant. For the estimation of Mineral Resources, the CaO content was considered and the impurity content. The impurities are restrictions determined by the cement production plant. Table 26 shows the Resources and the average values of their quality.

 

Table 26 Resource categorization (exclusive of Reserves) at the Tioyacu quarry

 

  Resources Tonnes M CaO (%) Al2O3 (%) MgO (%) Si2O (%) K2O (%)
Limestone Measured 0.05 50.10 0.60 1.01 5.82 0.22
Indicated 0.5 48.01 0.67 3.32 6.23 0.19
Measured + Indicated 0.5 48.20 0.67 3.11 6.19 0.20
Inferred 19.8 46.34 0.37 5.97 2.67 0.14

11.8.1.Cut-off

 

The main factor for the determination of Resources is quality. The costs of production, transportation, cement processing, and cement dispatch were considered to determine the Resources. The costs are based on real sources of the current operations of Cementos Selva S.A.C. Chapter 19 shows the economical analysis for determining the mineral Resources.

 

11.8.2.Reasonable Prospects of Economic Extraction

 

The Mineral Resource evaluation has considered relevant economic and technical factors such as limestone production costs, cement sales prices, and environmental and social viability at our operations.

 

The area associated with the Resource estimate is located at the lower boundary of the mining concession. Complement the geological information towards the S-SW zone of the quarry, considering future production activities.

 

The Resource estimate considers the Tioyacu deposit as 90 m. thickness, defined by quality and continuity.

 

The all material produced in the Tioyacu quarry is blended to be sent to the plant. The quality of this material is analyzed in the Rioja plant laboratory before blending.

 

Update the geomechanical and hydrogeological studies of the quarry to consider future open-pit mining to the south.

 

The information that supports the estimation of the quarry’s Resources is consistent, which allows obtaining a robust resource model.

 

From the environmental and social point of view, Cementos Pacasmayo (included Cementos Selva) has been developing activities in Peru for more than 60 years and is recognized as a Peruvian company with a high reputation, therefore, it is expected that the environmental and social viability will continue.

 

49

 

 

11.8.3.Mineral Resources classification

 

Cementos Selva S.A.C. obtained the parameters for classifying Resources based on staff´s experience designing the optimal drilling grid for sampling by geostatistical methods. Additionally, the variogram analysis was used as reference. Based on these, the following basic criterio is used to define the Resource classes:

 

-Measured Resource: 1/3 of the distance of the variogram range.

 

-Indicated Resource: 2/3 of the distance of the variogram range.

 

-Inferred Resource: The total distance of the variogram range.

 

Several configurations have been defined from this basic configuration, taking into account the number of drill holes and the average search distance.

 

Associated with the uncertainty, QP considered the criteria in Table 27 to categorize the Resources. The table shows the number of composites, drill holes and distance used for the various resource categories.

 

Table 27 Criteria for Resource categorization

 

  Measured Indicate Inferred
Minimum number of composites 2 2 1
Maximum number of composites 20 20 20
Number of composites drillhole 2 2 1
Average distance of composites (m) 90 135 180

 

11.9.Qualified Person’s Opinion

 

The QP has considered the quality and geological characteristics of the limestone horizons to develop the geological model. Likewise, the QP’s interpretation of the deposit was based on the diamond drill holes obtained in the drilling campaigns. The opinion of the QP is that there is consistency between the information and the geological model. As a producing mine, most of the relevant technical and economic factors have already been resolved.

 

The expansion of the pit towards the southern area of the deposit is necessary to guarantee the production of limestone in the future. It is important to start the development and preparation in that direction with the construction of the access ramp to complement the second phase of the diamond drilling campaign that started at the end of the year (2023), to allow the update that makes the geological model more robust and helps reduce uncertainty, as well as allowing the confirmation of resources and recategorizing inferred resources.

12.Mineral Reserves estimates

 

Total Mineral Reserves estimated at the Tioyacu quarry are 10.3 million tonnes, as detailed in Table 24 in their different categories.

 

Additionally, the periodic update of the Mineral Reserves of the Tioyacu quarry takes into account the Reserves extracted when updating the Mineral Resources and Reserves models, any new “modifying factors”, or the change and entry of any new data.

 

The calcium oxide (CaO) content is the primary variable in the Mineral Resources and Reserves estimation. Its specific values depend on the lithological domain, with its concentration higher in some lithologies than in others.

 

The calculated Reserves in the limestone deposit was 5.9 M mt. of proven Reserves with 50.17% CaO and 4.4 M mt. of probable Reserves with 48.07% CaO for a total of 11.3 M mt. of Reserves with 49.28% CaO that support the mining plans for production and supply to the Cementos Selva S.A.C. plant.

 

Based on the estimated Reserves and the plant’s projected limestone consumption, the QPs estimate a life of mine of 24 years for the quarry.

 

12.1.Criteria for Mineral Reserves estimation

 

The criteria used for the determination of Mineral Reserves are described below.

 

12.1.1.Run of Mine (ROM) determination criteria

 

ROM is considered to be all material produced in the quarry that complies with the specifications and will be sent to the plant for cement production. For determining ROM tonnage, dilution was considered to be negligible. The recovery in the quarry was assumed to be 100%.

 

51

 

 

12.1.2.Cement Plant recovery

 

The limestone received at the Rioja plant is properly stored and then mixed with other raw materials to obtain the raw meal feed (kiln feed). The crude contains 73.26% limestone. After the crude is obtained, it is fed to the calcination kiln to obtain clinker. Finally, the clinker is mixed with additives to obtain cement.

 

12.2.Reserves estimation methodology

 

The Mineral Reserve estimation considers the costs of production, transportation, cement processing, and the quality restrictions of the raw material. The costs are based on actual costs from the current operations of Cementos Selva S.A.C. at the Tioyacu quarry and Rioja plant. Chapter 19 shows the economical analysis used to determine the Mineral Reserves.

 

Proven and Probable Reserves are derived from Measured and Indicated Resources, respectively.

 

Proven and Probable Reserves are within the pit designed for the Tioyacu quarry.

 

Reserves are those for which economic viability has been demonstrated by discounted cash flow analysis based on estimated capital and operating costs.

 

Cementos Selva S.A.C. has permits for limestone production at the Tioyacu quarry. All material considered to be Mineral Reserves are material for which CSSAC has mining permits.

 

The effective date of the Reserve estimate is December 31, 2023.

 

The Reserve estimate is the final product placed in the Rioja plant.

 

12.3.Reserves estimates

 

Reserves are expressed in tons and are shown in Table 28.

 

Table 28 Mineral Reserves expressed in millions of tonnes

 

  Reserves Tonnes M CaO (%) Al2O3 (%) MgO (%) SiO2 (%) K2O (%)
Limestone Proven 5.9 50.17 0.61 1.01 5.86 0.22
Probable 4.4 48.07 0.72 2.18 6.84 0.21
Total 10.3 49.28 0.66 1.51 6.28 0.22

 

52

 

 

12.4.QP’s Opinion on Risk Factors affecting Reserve Estimates

 

In the QP’s opinion, the Reserves estimated for the quarry from the Resources consider the relevant risk factors and modifying factors which affect the tonnage and quality estimates. The primary variable is considered to be CaO, which is very stable in the deposit. SiO2 is viewed as a secondary variable that, without adequate control, can have an inverse effect on the CaO content in the Reserves. MgO is a secondary control variable that is also taken into account to define the reserves, in the current report its average is slightly above the recommended level, which with an efficient mixing process is manageable, also with the objective of improving the quality support in the reserves it is planned to carry out a diamond drilling program in the quarry.

 

In estimating Reserves and the production plans for the quarry, these variables have been adequately considered with production sequencing and blending processes.

 

Because the Cementos Selva has been operating the Tioyacu quarry for 23 years and the deposit is relatively stable in the main quality metrics, the QP is of the opinión that the risks associated with the Reserve estimate is low.

 

In addition to quality factors, ore reserves could change from operating performance-controlled production costs, allowing for maximization of the use of resources in the extractive processes for the use of resources in the extractive processes for the industrialists, guaranteeing the LOM of the quarry.

 

13.Mining methods

 

Cementos Selva S.A.C., a wholly-owned subsidiary of Cementos Pacasmayo S.A.A, is the current owner of the Tioyacu quarry. Cementos Selva S.A.C. carries out the planning, production, supervision and quality control of the quarry to verify the activities and production according to the requirements of Rioja plant.

 

13.1.Mining methods and equipment

 

The production of the deposit begins with the drilling and blasting. The fragmented material is pushed with a dozzer to create muckpiles before loading the material into dump trucks using a front loader. The material is transported to the cement plant.

 

The quarry activities allow the production of fragmented limestone smaller than 12” in diameter, with carbonate grades according to the plant’s needs.

 

53

 

 

The sequence of limestone extraction is by benches, which are produced sequentially according to the annual requirement of the plant.

 

Figure 9 Tioyacu quarry mining sequence

 

 

 

Limestone mining at the Tioyacu quarry comprises the following unit operations:

 

Drilling

 

Drilling activities at Tioyacu quarry are carried out with one diesel-powered drilling rig and one as stand-by.

 

Blasting

 

Blasting allows the rock to be fragmented to a size suitable for loading, hauling, and crushing unit operations. Non-electric detonators and connectors are used to avoid vibration and sound.

 

Loading and Transportation

 

There are 04 Volvo dump trucks of 14 m3 capacity, 02 excavator CAT and 01 front loader CAT 962L.

 

54

 

 

The main equipment used to carry out mining activities at the Tioyacu quarry are shown in Table 29.

14.Processing and recovery methods

 

14.1.Process Plant

 

Cement production involves the following stages:

 

Production of raw materials. Limestone is produced from the Tioyacu quarry, as described in Chapter 13.

 

Milling and homogenization. Once the limestone is received at the plant, it is dosed to the raw mill with clay, iron, and coal. The mixture must meet the quality standards to be sent to a storage silo from where it is fed to the crude storage silo. The crude is fed to the kiln for clinker production.

 

Clinkerization. The mixture is pelletized and then enters the vertical kiln where it reaches a temperature of approximately 1,450 degrees Celsius, the product of which is clinker. The clinker is then cooled to about 200 degrees Celsius and stored in silos or storage bins.

 

Cement grinding. After being cooled, the clinker, together with gypsum and some additives, is fed into a mill to obtain cement.

 

Storage in silos. After passing through the mills, the cement is transferred to conveyor channels and stored in concrete silos to preserve its quality until distribution.

 

Packing, loading, and transportation. Cement is transferred through chutes from the silo to be packed into 42.5-kilogram bags in bagging machines, and then stored or loaded onto trucks operated by third parties for distribution. Bulk cement is transported by trucks.

 

14.2.Raw materials for the cement production

 

The following raw materials and additives are used in the Rioja plant to produce cement.

 

Raw Materials

 

59

 

 

Limestone, is composed mainly of calcium carbonate and is used as raw material and an additive in cement production.

 

Iron, is inert material composed basically of iron oxide (Fe2O3).

 

Clay, is inert material composed of silicon, aluminum, and a low proportion of alkalis such as potassium and sodium.

 

Coal, is a solid, black, or dark brown mineral that is essentially carbon with small amounts of hydrogen, oxygen and nitrogen.

 

Gypsum. It is a material composed of calcium sulfate hydrates. When gypsum is mixed with the clinker, it controls the setting time when the cement initiates the hydration reactions.

 

Crude, is an artificial mixture of limestone, clay, iron, and coal used to produce clinker.

 

Clinker is a product obtained from limestone, clay, iron, and coal.

 

Additives

 

Limestone.It is a material composed mainly of calcium carbonate, which, when finely ground, is used as an additive in cement production.

 

Gypsum. It is a material composed of calcium sulfate hydrates. When gypsum is mixed with the clinker, it controls the setting time when the cement initiates the hydration reactions.

16.Market Studies

 

Cementos Selva S.A.C is a subsidiary of Cementos Pacasmayo. Cementos Pacasmayo is a leading company in the cement production and other construction materials in the north of Peru. This chapter describes the cement market, as well as the macro and microeconomic factors that define it.

 

For the description of the cement market in Peru, public information has been collected from different sources, such as the Central Reserve Bank of Peru (BCRP), National Institute of Statistics and Informatics (INEI), Association of Cement Producers (ASOCEM), Ministry of Housing, Construction and Sanitation, Superintendence of Tax Administration and the Peruvian Construction Chamber. In addition to this information, this chapter also relies on statistics provided by the company (CPSAA) to provide a better understanding of its specific market.

 

16.1.The cement market in Peru

 

The Peruvian cement market is geographically segmented by regions: north, central and south. Diverse companies supply each region. Figure 12 is an illustration of the Peruvian map and of its 3 regions, according to the segmentation of the cement market, where each region is the main area of influence of domestic cement companies.

 

Figure 12 Segmentation of the cement market in Peru

 

 

 

The main companies that comprise the cement market in Peru are: Cementos Pacasmayo S.A.A., UNION Andina de Cementos S.A.A., Yura S.A. and Cementos Selva S.A.C. Additionally, there are companies that import cement or clinker, such as Caliza Cemento Inca S.A., Distribuidora Cemento Nacional S.A.C., CEMEX Perú S.A., Cal & Cemento Sur S.A., amongst others.

Rioja plant shipments   336.8    305.8    257.1 

 

Sources: ASOCEM, CPSAA/CSSAC

 

The types of cement produced by the main cement companies in the country are Type I, Type V, Type ICO, Type IL, Type GU, Type MS (MH), Type HS, Type HE, Type MH.

 

It is important to mention that, according to the main requirement standards, Peruvian Technical Standards, cements are divided into five types:

 

NTP 334. 009 2013. Cements Portland. Requirement. (ASTM C 150).

 

NTP 334. 090 2013. Cements Portland Added. Requirements. (ASTM C595).

 

NTP 334. 082 2011. Cements Portland. Performance Specification. (ASTM C1157).

 

NTP 334. 050 2004. Cements Portland White. Requirements. (ASTM C150).

 

NTP 334. 069 2007. Building Cements. Requirements. (ASTM C091).

 

For Cementos Selva’s cement products, only the first 3 NTP standards apply.

 

16.2.Industry and Macroeconomic Analysis

 

Producers and trading companies of cement compete mainly within the limits of their area of influence, which is determined by the geographical location of their plants, giving rise to segmentation of the national market. However, the northern region presents a high demand potential because of the infrastructure gap, the housing deficit and a higher capillarity in terms of important cities adjacent to one another and with an urbanization level lower than in the central and southern region. On the other hand, it is important to note the importance of transportation in the structure of cement costs, which are composed primarily of raw materials, fuels and transportion.

 

66

 

 

The cement market and industry in Peru have the following characteristics:

 

Base of consumers highly segmented, informal and of low resources.

 

Low costs of energy and raw materials.

 

Zone of influence / distribution determined by geographical location of the plant.

 

High correlation between public and private investment, and self-construction.

 

The construction sector and cement industry have a behavior directly related to the Gross Domestic Product (GDP) and Private Consumption. Figure 13 shows how the GDP of the construction sector (monthly variation %) tracks the cyclic behavior of the Global GDP (monthly variation %), showing variations of lower significance than those of the Global GDP, but in the same direction. It is also noted that, in May 2020, the GDP of the construction sector had a positive variation of more than 200% (compared to the previous month), whilst Global GDP went up only 10%. This was due to the reactivation of economic activity and consumption once the confinement measures given by the Government to counter the Covid-19 pandemic were loosened. This reactivation was motivated primarily by private-construction sector consumption. In the face of the uncertainty caused by the health and economic crisis in 2020, consumers showed savings behaviors, which meant that people preferred consumption of goods for home improvement, amongst them, cement. This trend was maintained throughout 2021. However, in 2023 there was a decrease in demand for public and private investment due to the political and social situation. As a result, cement volumes are returning to pre-covid levels.

The cement industry is also motivated by housing sector growth, public and private investment in infrastructure, mining projects, shopping centers, construction of transportation systems, etc. Thus, one of the variables with more impact on cement industry and future demand is the infrastructure gap which remains high in the country.

 

For the 2016 – 2025 period, the infrastructure gap is estimated to be US$ 160 billion and this is present in the main economic sectors and services of public supply, that is: Transportation (36%), Energy (19%), Telecommunications (17%), Health (12%), Sewage System (8%), Irrigation (5%) and Education (3%). The 90% of the roads not included in the large national road network still remain without pavement. Only 40% of schools have access to basic services such as water, electricity and sewage system. There are only 15 hospital beds for every 10,000 individuals compared to 27 beds recommended by the WHO.

 

In 2023, the cement market contracted by 14% compared to 2022, while it grew by 20% in 2019 (pre-pandemic). However, by 2024, it is expected to have x% growth compared to 2023. Climatic (cyclone Yaku) and social (protests and blockades) factors impacted domestic cement dispatches. In addition, regional and local and local governments began new administrations with lower-than-expected public spending than expected.

 

Given greater stability in the sector, a moderate growth of 2% in cement shipments is expected by 2024.

 

16.3. The North Region Market

 

Cementos Pacasmayo, a leading company in the production and sales of cement in the North Region, has market presence in the following cities: Cajamarca, Chiclayo, Chimbote, Jaén, Pacasmayo, Piura, Rioja, Tarapoto, Trujillo, Tumbes, Yurimaguas and Iquitos. The company has a Market share of over 93.8% in the northern region of the country.

 

Cementos Selva S.A.C.’s overall shipments from the Rioja plant were 257,132 tonnes. It supplied 8.2% of the country’s North Region cement demand, and its cement sales represented 8.8% of the Company’s overall shipments.

 

68

 

 

Other companies with lower presence in the cement market of the North Region are:

 

Quisqueya - Cemex

 

Cemento Nacional

 

Cemento Inka

 

Cemento Tayka

 

These companies are competitiors of the Rioja plant.

 

Cementos Selva S.A.C.’s Rioja plant produces different types of cement and it has placed in the National Market different trademark products to meet the needs of diverse segments of the market. Table 40 shows the products in Rioja plant.

16.4.Cement price

 

The sale prices of cement in the Peruvian market vary pursuant to their type and their geographical location. The price difference between each type is explained primarily by the dosifications of raw materials and additives, whilst the variations for geographical location are caused by the freights for the distribution to the points of sale.

 

At domestic level, the cement price in 2023 was, on average, 690.59 S/ x t. Figure 14 shows the historical prices of cement in Peru.

Figure 14 shows the sustained growth of the price of more than 4% per year, from 2017 until 2018, it fell slightly in 2019 to climb back up again in 2020.

 

16.5.Current and future demand

 

Cement demand at the national level is met by local shipments (local production), for the most part, and by imports. In 2023, 11.20 M tonnes were shiped locally; 13.6% less than in the same period of 2022 (12.97 M). Imports amounted to 0.21 M tonnes during 2023; 21.9% below the 2022 figure (0.27 M).

It is noted that domestic demand has been growing, on average, at a rate of 3% per year, with the exception of 2020, which is considered an atypical year due to the adverse effects of the pandemic and the confinement measures, to then take a historic leap in 2021 with an annual increase of 38%. During 2023, shipments decreased by 13.8% compared to 2022 as a result of the political and social situation in the country.

 

According to our internal information, in terms of regional distribution, the Northern Region accounts for approximately 25.6% of domestic cement demand, the Central Region for 54.5%, and the Southern Region for 19.9%.

 

Cementos Pacasmayo’s cement shipments (3 plants) reached 2,936.6 thousand tonnes in 2023, capturing a 24.1% share of total shipments in Peru and 93.8% in the Northern Region. This is 15% less than in 2022 (3,436.8 thousand tonnes).

 

Despite the decrease in the volume of shipments in 2023, future demand is optimistic for the region due to the high infrastructure deficit.

17.Environmental studies, permitting, and plans, negotiations, or agreements with local individuals or groups.

 

17.1.Environmental Aspects

 

Cementos Pacasmayo has Corporate Policies that apply to the operations of quarries and cement plants. Relevant policies include Safety Occupational Health Policy, Quality Policy, and Environmental Policy.

 

17.1.1.Tioyacu quarry

 

On May 19, 2022, through Directorial Resolution No. 215-2022-PRODUCE/DGAAMI, the authority approved the Update of the Environmental Impact Study of “Tioyacu quarry limestone” in compliance with the obligations established in environmental legislation, assuming commitments in order to guarantee the environmental viability of operations in the quarry.

 

Subsequently, on November 24, 2022, through Directorial Resolution No. 545-2022-PRODUCE/DGAAMI, the authority approved the Supporting Technical Report for the “Estimation of reserves” project in the Tioyacu Limestone Quarry to determine the existence of greater reserves of limestone for subsequent exploitation through diamond drilling.

 

In 2023, CSSAC carried out environmental monitoring through the Laboratorio Envinmental Testing Laboratory S.A.C. - Envirotest, a company with accreditation before the International Accreditation Service (IAS) and the National Quality Institute (INACAL), both signatories of the ILAC-MRA International Mutual Recognition Agreement.

 

Envirotest was in charge of collecting and analyzing the samples, and presenting the results through reports to the Environmental Assessment and Enforcement Agency - OEFA, an institution of the Peruvian State in charge of reviewing and validating the information presented by the owner. At the Tioyacu quarry, parameters of gaseous emissions and particulate matter for air quality were measured every six months. The results obtained in 2023 are below the values ​​established in the Environmental Quality Standard (ECA) for air approved with Supreme Decree No. 003-2017-MINAM.

 

73

 

 

The results obtained from the environmental noise measurement activities in 2023 are below the Environmental Quality Standard Limit (ECA) in compliance with the provisions of Supreme Decree N°085-2003-PCM.

 

The biological and hydrobiological monitoring in the Tioyacu quarry was carried out by the Analytical Laboratory Laboratorio E.I.R.L. - ALAB and Environmental Testing Laboratory S.A.C. - Environmental test. The objective was to characterize the Vegetation, Herpetofauna, Avifauna and Mastofauna. The results showed an abundance of birdlife, a species typical of this type of vegetation where forest predominates.

 

About water management, it is essential to mention that Tioyacu quarry does not have any discharges. The small water consumption is only for green area irrigation and road maintenance.

 

The Environmental Management of the Manufacturing Industry and Domestic Trade, Supreme Decree No. 017-2015-PRODUCE, establishes the environmental management procedures covered by Ministerial Resolution No. 157-2011-MINAM for investment projects subject to the National System of Environmental Impact Assessment (SEIA) and its amendments.

 

Law No. 28090 and its Regulation approved by Supreme Decree No. 033-2005-EM establishes the closure measures for non-metallic quarries.  Directorial Resolution No. 178-2016-MEM-DGAAM, the Update of the Closure Plan of the Tioyacu quarry mining unit was approved, which establishes measures at the end of the useful life of the quarry.

 

The Closure Plan submitted by Cementos Selva S.A.C. has included the necessary measures to ensure effectiveness or consistency with the requirements necessary for the protection of public health and the environment. The initial strategy has continued with the Closure of the components of Tioyacu quarry mining unit, establishing temporary, progressive, final and post-Closure activities at the end and/or closure of operations.

 

74

 

 

Environmental closure activities have included physical stability in the mine, geochemical stability, water management facilities, decommissioning for the removal of equipment and machinery. Also infrastructure demolition, reclamation, waste disposal, landform establishment, habitat rehabilitation, revegetation and social programs.

 

Post-closure activities such as physical maintenance, geochemical maintenance, hydrological maintenance, and biological maintenance will be carried out, and post-closure monitoring activities include physical stability monitoring, geochemical stability monitoring, water management monitoring, biological monitoring, and social monitoring.

 

Considering that the land use before mining production was a secondary forest which was affected by other activities, forestation activities with native species have been considered part of the post-closure activities. Likewise, CSSAC will fulfill the commitments included in the Closure Plan approved by the above authority.

 

It is important to mention that the approval of the Mine Closure Plan involves the constitution of guarantees to ensure that the owner of the mining activity complies with the obligations derived from the Mine Closure Plan, in accordance with environmental protection regulations.

 

Cementos Pacasmayo has a guarantee of faithful compliance with the mine closure plan for the Tembladera quarry according to the approval of the updated mine closure plan for an amount of 441,584.00 USD.

 

We have a solid relationship with our communities and we have identified its main needs in health, education, urban development and local development.

 

We have a social investment program which contributes to dealing with their needs, based on good dialog and our compliance to our commitments to our communities.

 

The communities are a priority for Cementos Selva. For this reason, we promote periodic meetings with their representatives and we create opportunities for dialog to know their expectations. Also, we have established public and private alliances for development projects and programs to contribute to a better quality of life and to strengthen our relationship. In 2023, CSSAC worked in partnership with the district governments of Elias Soplin Vargas and Rioja.

 

75

 

 

CSSAC has no commitments for local procurement and hiring although it does its best to hire local talent and do business with local businesses.

 

17.1.2.Rioja plant

 

On August 3, 2022, through Directorial Resolution No. 346-2022-PRODUCE/DGAAMI, the Supporting Technical Report (ITS) of the project “Expansion of surface components of the Rioja cement plant” for the expansion of storage areas was approved of raw materials, bagging and materials that are received in said areas.

 

About water management, it is essential to mention that Rioja plant does not have any discharges. The small water consumption is only for green area irrigation.

 

Finally, in accordance with environmental regulations and according to the Regulation of Environmental Management of the Manufacturing Industry and Domestic Trade, Supreme Decree N° 017-2015-PRODUCE, companies that produce cement are required to submit Closure Plans when executing Decommissioning activities. To meet that requirement, Cementos Selva in compliance with Peruvian legislation will submit the Closure Plan in a timely manner.

 

17.2.Solid waste disposal

 

Cementos Selva S.A.C. has a Solid Waste Minimization and Disposal Plan for our production activities at the Rioja plant and Tioyacu quarry. Annually, our company declares the generation, storage, collection, and final disposal of hazardous and non-hazardous solid waste in compliance with environmental legislation.

 

The solid waste minimization plan (2023), we declared 0.2 tonnes of hazardous waste and 1 tonnes of non-hazardous waste for the Tioyacu quarry. Likewise, for the Rioja plant we declared 14.2 tonnes of hazardous waste and 771.6 tonnes of non-hazardous waste, which were disposed of in accordance with environmental legislation.

 

17.3.Qualified Person’s Opinion

 

Cementos Selva S.A.C. complies with national environmental standards in the industrial sector and to the International Standard Industrial Classification - ISIC 2694 for the non-metallic production of the limestone material for the manufacture of cement.

 

76

 

 

For the industrial and mining sector, the company specifically complies with the Environmental Management Regulations for the Manufacturing Industry and Domestic Trade, Supreme Decree No. 017-2015-PRODUCE, which is the rule that regulates the environmental management of the activities indicated in Ministerial Resolution No. 157-2011-MINAM and investment projects subject to the National System of Environmental Impact Assessment (SEIA), considered in Annex II of the Regulations of Law No. 27446, approved by Supreme Decree No. 019-2009-MINAM.

 

The company reports the environmental commitments, semiannually and quarterly to the Environmental Evaluation Agency - OEFA. The monitoring is carried out through external laboratories that provide comprehensive monitoring and analysis services and have double accreditation, by the international IAS (International Accreditation Service) and the national INACAL (National Institute of Quality), both signatories of the ILAC-MRA international Mutual Recognition Agreement.

 

Cementos Selva S.A.C. strictly complies with the protocols in the different processes in compliance with environmental legislation and reporting to the OEFA.

 

The qualified person believes that CSSAC’s current plans and management strategies are adequate for addressing any issues related to environmental compliance and maintaining its environmental permits. In addition, the qualified person believes that CSSAC has a good relationship with the local communities and that its social investment plans are adequate for reducing any social risks to the project.

 

18.Capital and operations costs

 

18.1.Basis for operating and capital costs for the quarry and plant

 

In a tabular manner, this section presents the operating costs of Tioyacu quarry for the production of limestone - the primary raw material used for cement production at the Rioja plant. It also exhibits the plant’s operating costs, for the whole industrial process; from the reception of raw material, to its conversion to the final product (cement). Cost forecast is mainly based on actual historical costs.

 

77

 

 

Similarly, this section reports the detail of the capital investments made in the quarry and plant, and the forecasted investment plan required to sustain all the activities in the quarry and plant and to assure the supply of limestone Reserves necessary to achieve the production levels according to the forecasted cement shipments of the Rioja plant.

 

Table 42 depicts the main components of the cost structure of Tioyacu quarry and Rioja plant and the sources used in their forecasts:

 

Table 42 Concepts about cost structure of Tioyacu quarry and Rioja plant

 

Concept Description Source

Considering that the Tioyacu quarry and the Rioja plant are in operation, the historical costs are the principal basis for estimating forecasted costs.

 

78

 

 

In this sense, the actual costs in some cases are maintained, and in other cases, are appropriately adjusted for factors specific to the quarry operation, conditions, and obligations stipulated in supply and concession contracts.

 

On the other hand, macroeconomic factors such as inflation and devaluation of the local currency against the US dollar could indirectly impact future operating costs estimation.

 

18.2.Capital and Operating Cost Estimates

In recent years, there have been no significant variations in capital investment, which correspond mainly to maintenance and replacement of equipment in the quarry and plant to sustain operations. The Company´s investment plan does not consider any unusual or expansion activity. It is solely planned to perform the necessary replacement for the quarry support and the maintenance of operations in the plant. The investments are kept at levels similar to those registered throughout the last few years.

18.3.Capital and Operating Cost Estimation Risks

 

There is a low risk associated with capital and production costs because mine production and cement plant operation will continue in the same geological deposit and using the same mining and industrial methods.

 

An assessment of the accuracy of estimation methods is reflected in the sensitivity analysis in Section 19.

 

For purposes of the Preliminary Feasibility Study completed relative to the Tioyacu quarry and Rioja plant, capital and operating costs are estimated to an accuracy of +/- 25%.

  

19.Economic Analysis

 

19.1.Methodology: Discounted Cash Flow (Free)

 

The Economic Analysis chapter describes the assumptions, parameters and methodology used to demonstrate the economic viability or profitability of extracting the mineral Reserves. That is, the pre-feasibility level support for the determination of mineral Resources and Reserves, by means of a business valuation through the Discounted (Free or Economic) Cash Flow method.

 

The horizon of the cash flow projection is consistent with the life of the quarry, which is calculated based on the total declared Reserves and the annual production at the quarry. Each period’s cash flow is approximated indirectly from the EBITDA (the latter is constructed in the Profit and Loss Statement), and the corresponding adjustments are made for taxes and capital costs (CapEx).

 

Finally, for this economic analysis we use the free cash flow, since it does not incorporate the company’s capital structure, and we apply the weighted average cost of capital (WACC) for discounting future cash flows.

 

19.2.Assumptions

 

19.2.1.General and Macroeconomic Assumptions

 

The general and macroeconomic assumptions used for the projection of economic cash flows and the valuation are:

 

Projection horizon: 24 years (2024 to 2047) according to the estimated years of quarry life.

 

The annual escalatioin rate; 2.90%, based on The International Monetary Fund as of October 2023: applies equally to the sales price, costs, and expenses.

 

Capital cost projections were determined using a historical ratio of annual investments and maintenance costs, which also considers the increase in production volume.

 

The company’s financing structure is being considered in the discount rate (WACC), which is 11.56%.

 

Income tax rate: effective rate of actual (historical) business results, 29% - 30%.

 

Workers’ Profit Sharing: 10%.

 

Exchange rate: exchange rate is assumed to remain at 3.80 (USD/PEN).

 

81

 

 

19.2.2.Income and Cost Assumptions

 

The sales price of cement, expressed as S/ x t, is the sales price of the Rioja plant to Dino Selva Iquitos, FOB at Rioja plant; which is lower than the sales price to the final customer in the market. The distribution freight explains this difference to the multiple points of sale and the selling expenses associated with distribution and promotion in the different commercial channels.

 

The base price used in the projection is an estimate for the year 2024 (561.2 S/ x t), which has been determined based on current market conditions and cement demand for 2024, among other factors.

 

Starting in 2025 (year 2 of the projection), an annual price escalation rate of 2.9% is applied the sales prices.

 

The cost of cement production, expressed as S/ x t, has been estimated for 2024 based on actual operating expenses, the market situation of local materials and services, plant demand for imported clinker, and other factors. The cost of production for year 2024 is 342.5 S/ x t.

 

Starting in 2025, an annual cost escalation rate of 2.9% is applied to the cost.

 

The initial stock of products in the quarry and plant is assumed to be zero.

 

19.3.Financial Model Results

 

The following financial parameters were calculated:

 

NPV of 363 million Soles at a discount rate of 11.56%.

 

24-year mine life, because of the update of the maximum capacities of the vertical kilns of Planta Rioja.

 

Average plant throughput of 0.4 million tonnes per year over the 24-year projection.

 

Average sales price of 724.6 Soles per ton of cement, on average for the 24-year projection, at nominal values.

 

82

 

 

Revenues of 275 million Soles, on average for the 24-year projection.

 

Average cash production cost of 469.4 Soles per ton of cement, on average for the 24-year projection, at nominal values.

The net present value (NPV) of Rioja plant cement business amounts to almost S/ 363 million and it is made up of the sum of the discounted cash flows of each period, for the 24-year projection.

 

For discounting of the cash flows, the weighted average cost of capital of the company (WACC for its acronym in English) was applied.

 

19.4.Sensitivity Analysis

 

The sensitivity analysis considers a variation of +/- 5 and 10% in the variables that have the greatest impact on the NPV and EBITDA. These variables are the cement sales price, operating cost and CapEx.

 

Tables 47 and 48 detail the sensitivity of the NPV and EBITDA to each variable, respectively, when the variables are varied independently. Figures 16 and 17 show the results of the sensitivity of NPV and EBITDA, respectively, to the three variables:

 

Table 47 Sensitivity analysis of the Net Present Value

 

Variable / Variation -10% -5% 0% +5% +10%
Price -33.6 -16.8 0 18.8 33.6
Cost 22.1 11.1 0 -11.1 -22.1
CapEx 1.1 0.5 0 -0.5 -1.1

 

Table 48 Sensitivity analysis of the EBITDA

 

Variable / Variation -10% -5% 0% +5% +10%
Price -32.1 -16 0 16 32.1
Cost 21.2 10.6 0 -10.6 -21.2
CapEx -0.1 0 0 0 0.1

 

85

 

 

Figure 16 Sensitivity of Net Present Value

 

 

 

Figure 17 Sensitivity of EBITDA

 

 

 

Based on these results, the NPV is most sensitive to cement price, followed by operating cost, and least susceptible to the CapEx. EBITDA has a similar sensitivity to NPV, being most exposed to cement price, followed by operating cost, but shows no sensitivity towards variations to the CapEx.

21.Other relevant data and information

 

Not applicable.

 

22.Interpretation and conclusions

 

From a legal point of view, Cementos Selva S.A.C. has the ownership of the mining properties for the exploration, development and production of limestone to supply the cement plants for normal production during the life of the quarry.

 

Cementos Selva S.A.C. has been complying with international ISO-9001 standards since 2015 and has implemented Quality Assurance and Quality Control (QAQC). The controls are applied for the construction of the Geological Model, Resource estimation and Reserves estimation.

 

Cementos Selva S.A.C. has a quality assurance system in its operations that includes sample preparation methods, procedures, analysis and security, which comply with the best practices in the industry.

 

The information verification and validation processes are carried out following the procedures indicated in the information flows. The validated information is congruent with the one that generated the geological models, which is the fundamental basis for the estimation of Resources.

 

The geological modeling of the limestone deposit is consistent with the relationship between the information and the geological model.

 

The Mineral Resource and Reserves estimation considers the geologic charateristic and modifying factors as well as due consideration of risk: geologic and associated with evaluation of modifiying factors. The main quality variable is the CaO content which is very stable in the deposit. There are other secondary variables that determine the quality of the Reserves.

 

In the process of estimating Mineral Reserves and in the production plans of the quarry these variables have been adequately considered in the mining plan, properly sequenced, and with blending processes. There are sufficient proven and probable Reserves for the next 24 years.

The cement plant located in Rioja has equipment and facilities available for cement production, using limestone from the Tioyacu quarry and other necessary materials.

 

The Health, Safety and Environment department is in charge of supervising and ensuring compliance with the Company’s corporate policies and the various legal requirements of the national regulatory bodies by all company departments.

 

Through its Social Responsibility department, Cementos Selva S.A.C. has built relationships of trust with the communities surrounding its operations, identifying their primary needs in health, education, urban development and local development.

 

Infrastructure-wise, the operation in Tioyacu quarry and Rioja plant, in relation to infrastructure, is technically and economically feasible due to the life of the quarry.

 

The sensitivity analysis shows that the operation is economically robust.

 

89

 

 

23.Recommendations

 

Maintain the QaQc program for exploration, development and production activities associated with cement production.

 

Include QaQc plans and density control for the subsequent diamond drilling campaigns.

 

It is recommended to finish the drilling campaign that began in 2023 and carry out the geological interpretation of the data generated during the campaign, so that it can be incorporated into the Resource and Reserve model, which will provide greater support and robustness to these model.

 

Implement the Geotechnical Monitoring Plan of the quqrry componets with the installation of slope displacement control lamdmarks.

 

Maintain a permanent monitoring of the installed piezometers both for water levels and water quality, to evaluate the evolution of levels during the production of the Tioyacu quarry.

 

It is recommended that a geophysical study using the Georadar method to identify karst cavities within the quarry area be conducted, especially in areas of structural anomalies.
