The following discussion provides information that management believes is relevant to an assessment and understanding of the condensed consolidated financial condition and results of operations of Southern Copper Corporation and its subsidiaries (collectively, "SCC", "the Company", "our", and "we"). This item should be read in conjunction with our interim unaudited Condensed Consolidated Financial Statements and the notes thereto included in this quarterly report. Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 2021.

EXECUTIVE OVERVIEW

Business: Our business is primarily the production and sale of copper. In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products. Our management, therefore, focuses on value creation through copper production, cost control, production enhancement and maintaining a prudent capital structure to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our aim is to remain profitable during periods of low copper prices and to maximize financial performance in periods of high copper prices.

We are one of the world's largest copper mining companies in terms of production and sales and our principal operations are in Peru and Mexico. We also have exploration programs in Chile, Argentina and Ecuador. In addition to copper, we produce significant amounts of other metals, either as a by-product of the copper process or through a number of dedicated mining facilities in Mexico.

Outlook: Various key factors will affect our outcome. These include, but are not limited to, the following:

Sales structure: In the first quarter of 2022, approximately 78.0% of our ? revenue came from the sale of copper; 10.0% from molybdenum; 3.8% from silver;

3.6% from zinc; and 4.6% from various other products, including gold, sulfuric

acid and other materials.

Copper: In the first quarter of 2022, the LME copper price increased from an

average of $3.85 per pound in the first quarter of 2021 to $4.53 (+17.7%). ? Currently, we are seeing prices in the range of $4.40 to $4.50, which remains

higher than the 2021 average of $4.23 per pound and bodes a positive outlook

for the Company. We believe the following factors are influencing the market:

? The most relevant market intelligence houses for the copper market are

expecting a market deficit for 2022 of about 100,000 tonnes.

This assumes growth in demand of 2.0 -2.5% in 2022, particularly in terms of

? cathode consumption in the U.S. An economic slowdown is expected in China due

to the recent COVID-19 outbreak.

Uncertainty regarding future production growth in Chile and Peru, which

? together represent about 40% of the global supply. Chile registered a

production drop of 7.0% in the first quarter of 2022, while 20% of Peru's

production is currently at risk due to social conflicts.

? Russia's copper supply (about 400,000 tonnes per year) has been shut out of the

market due to the invasion of Ukraine.

Molybdenum: Represented 10.0% of our sales in the first quarter of 2022 and is ? currently our most important by-product. Molybdenum prices averaged $18.99 per

pound in the first quarter of 2022, compared to $11.19 in the same period of

2021. This represented a 69.7% increase.

Regarding this by-product, we believe that prices will be supported by lower exports from China; an uptick in delivery times; and port congestion. We expect these factors will help maintain prices at good levels.

Molybdenum is mainly used in the production of special alloys for stainless steel that require significant hardness and corrosion and heat resistance. New uses for this metal are associated with lubricants, sulfur filtering of heavy oils and shale gas production.

Silver: Represented 3.8% of our sales in the first quarter of 2022. We believe ? that the prices for silver will be supported by its intensive level of

industrial use and the fact that, like gold, it represents value shelter in

times of economic turmoil.

Zinc: Represented 3.6% of our sales in the first quarter of 2022. We consider ? zinc has very good long term fundamentals due to high levels of industrial

consumption and expected production.

Production: For 2022, we expect to produce 895,800 tons of copper, which ? represents a decrease of 6.5% compared to 2021. Production will continue to be

affected by the stoppage at Cuajone and by the temporary reduction in ore

grades and recoveries at the Peruvian operations.

We expect our copper production to bounce back in 2023 and reach 971,200 tonnes as we get Peruvian production back on track and generate new production through our projects at Pilares and Buenavista-Zinc Concentrator.

We also expect to produce 25,300 tonnes of molybdenum, which represents a decrease of 16.4% over our 2021 production levels. In 2022, we expect to produce 18.7 million ounces of silver, which represents a slight decrease of 2.4% over our 2021 production level. Additionally, we expect to produce 69,700 tonnes of zinc from our mines, up 4.1% from 2021 production.

Capital Investments: In the first quarter of 2022, we spent $205.2 million on ? capital investments; this represented 25.6% of net income and an decrease of

11.8% compared to the amount registered for the same period in 2021.

CYBERSECURITY

Our operations depend upon information technology systems that may be subject to disruption, damage or failure from different sources, including, without limitation, installation of malicious software, computer viruses, security breaches, cyber-attacks and defects in design. In recent years, cybersecurity incidents have increased in frequency and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and the corruption of data. We have implemented appropriate preventative measures to mitigate potential risks by implementing an information security management system, which ensures application of controls that are frequently reviewed and tested.

In March 2021, we experienced a Ransomware cyber-attack, which was conducted by individual hackers. This cyber-attack encrypted a total of 420 servers and units of personal equipment. However, due to the quick response of our IT team, our Enterprise Resource Planning software was not affected by the aforementioned attack.

After the attack, we immediately began a remediation and recovery process and completely restored the affected servers. The forensic investigation did not identify concrete evidence that any information was stolen during the attack. However, we maintain active lines of cyberintelligence and continue to monitor the DarkWeb/DeepWeb and social networks to identify any publication or activity related to the Company to validate the technological controls affected during the attack and ensure that our systems infrastructure remains secure.

In March 2021, we appointed a new head of the Information Technology Department, who implemented a new information security strategy to ensure business continuity based on processes (controls and corporate governance framework), technology and human capital (organizational culture). In July 2021, Grupo Mexico appointed a Chief Information Security Officer, who has been actively involved in the development and implementation of this information security strategy. In addition, from July to September of 2021, we performed a cybernetic forensic



                                       37

analysis with the assistance of a professional consulting firm with international experience in this area. The recommendations received were integrated in current information security programs.

Additionally, AMC set up a task force to oversee ongoing initiatives and ensure that targets are met. We are actively following this matter with the task force, our internal audit team and; will also require the expertise of third parties.

Our new information security strategy is being executed on a continuous basis. The compliance, internal control, information technology and internal audit departments are all working together to integrate reference frameworks, risk management models and the necessary controls to continue executing this strategy and corresponding programs. To support our commitment to the strategy, we are working under the international framework for reference and standard, such as ISO, COBIT and NIST, to certify the Company´s security systems. The Company has also established an information security culture with the purpose of training, communicating and maintaining permanent awareness among the workforce. On the governance framework side, the Company has created a Committee of Information Security and set up security policies and standards, among other actions.

For 2022 we have a non-material special budget to continue improvements in this area.

CUAJONE STOPPAGE OF OPERATIONS

On February 28, 2022, a small group of protesters from the community of Tumilaca, Pocata, Coscore and Tala, which have of 472 residents in total, seized the facilities at the Viña Blanca water reservoir and cut off the water supply to the homes of the approximately 5,000 people who live in Cuajone. Prior to this illegal action, on February 18, 2022, the railway between Cuajone and Ilo was also blocked by a group of community members. They claim, the Company usurped their land and demand compensation of $5.0 billion, in addition to the permanent payment of 5% of net profits.

As of March 31, 2022, the Cuajone operations remained closed with an estimated production loss of 12,869 tonnes of copper content and 296 tonnes of molybdenum, which translates into a reduction in sales for $117. We also recorded $7.9 million of unabsorbed fixed costs, which directly impacted the cost of sales.

The impact to our results and financial position is not material as of March 31, 2022. Sales contracts were not significantly affected and measures were taken to acquire concentrates from our Mexican Operations and third parties to maintain and adequate supply to the smelter. This prevented a force majeure event from delays in fulfilling our sales sales commitments.

After several unsuccessful attempts by the authorities to restore order through dialogue efforts, on April 20, 2022, the Peruvian government declared a state of emergency in the Moquegua region. On April 21, 2022, the protesters returned the installations of the Viña Blanca water reservoir and the railway to the Company. Our personnel immediately evaluated the damage caused to the facilities by acts of vandalism and took the necessary steps to resume production at the Cuajone mining unit. As of today, the industrial railroad and the Cuajone mine, concentrator and related facilities are operating at full capacity.

On April 30, 2022, the Peruvian government issued a Ministerial Resolution to set up a three-party-round-table for dialogue with members of the community, government and Company officers to better understand all parties' concerns.

ECONOMIC CONSEQUENCES OF RUSSIA´S INVASION OF UKRAINE

The Ukraine-Russia war that broke out in February of 2022, has generated a series of impacts in the global economy and on international trade. This has forced companies to adjust their supply and commercial plans to deal with shipping delays for goods and higher prices for the same. The increase in the cost of oil and energy, coupled with saturation at ports, which was already high due to a surge in global economic activity after the COVID-19 pandemic ebbed, has driven up the prices of the vast majority of products and generated uncertainty in economies. This

situation is also affecting the countries in which we operate and in which our clients and suppliers operate, although the extent of the impact varies.

As of March 31, 2022, the impact of these events were not material for the Company due to our continuing cost efficiency programs. We are monitoring and adjusting our supply schedules to reflect the delay in the delivery of our critical supplies. Currently, our sales program has suffered no impacts.

KEY MATTERS

Below, we discuss several matters that we believe are important to understand the results of our operations and financial condition. These matters include, (i) our earnings, (ii) our production, (iii) our "operating cash costs" as a measure of our performance, (iv) metal prices, (v) business segments, (vi) the effect of inflation and other local currency issues, and (vii) our capital investment and exploration program.

Earnings: The table below highlights key financial and operational data of our Company for the three months ended March 31, 2022 and 2021 (in millions, except copper price, percentages and per share amounts):



                                             Three months ended March 31,
                                    2022         2021       Variance     % Change
Copper price LME                       4.53         3.85         0.68        17.7 %
Pounds of copper sold                 458.4        529.6       (71.2)      (13.4) %
Net sales                         $ 2,763.8    $ 2,532.5    $   231.3         9.1 %
Operating income                  $ 1,470.1    $ 1,351.6    $   118.5         8.8 %

Net income attributable to SCC $ 784.7 $ 763.8 $ 20.9 2.7 % Earnings per share

Dividends per share               $    1.00    $    0.60    $    0.40        66.7 %


Net sales in the first quarter of 2022 were 9.1% higher than in the same period of 2021, which was primarily attributable to higher metal prices for copper (+17.7%), molybdenum (+69.7%) and zinc (+36.0%), as well as to an increase in the sales volume of zinc (+98.8%). This was offset by a decrease in silver (-8.5%) prices as well as decreases in sales volume of copper (-13.4%), molybdenum (-2.4%) and silver (-16.8%).

Net income attributable to SCC in the first quarter of 2022 was 2.7% higher than in the same period of 2021. This growth was mainly attributable to the increase in metal prices and sales volumes mentioned above.

Production: The table below highlights our mine production data for the three months ended March 31, 2022 and 2021:

Total mined copper           472.8    525.6      (52.8)      (10.0) %

First quarter: Mined copper production in the first quarter of 2022 fell by 10.0% to 472.8 million pounds compared to 525.6 million pounds in the first quarter of 2021. This was mainly attributable to a drop in production at our Cuajone (-38.5%), Toquepala (-12.6%), La Caridad (-10.8%) and IMMSA (-20.4%) mines due to lower grades. This effect was offset by higher production at our Buenavista (+2.5%) mine due to higher ore grades.

Molybdenum production decreased 2.3% in the first quarter of 2022 compared to the levels registered in the first quarter of 2021. This was attributable to an increase in production at our Toquepala (+9.0%) and Buenavista (+15.8%) mines due to higher ore grades and recoveries. This effect was partially offset by a decrease in production at the Cuajone (-42.0%) and La Caridad (-2.2%) mines due to lower ore grades.

Silver mine production decreased 13.4% in the first quarter of 2022 due to a drop in production at the Toquepala (-24.4%), Cuajone (-34.8%), La Caridad (-5.7%) and IMMSA (-15.1%) operations. This was offset by a higher production at the Buenavista (+2.6%) mine.

Zinc production decreased 10.6% in the first quarter of 2022 compared to the same period of 2021. This decrease was mainly attributable to lower production at the Santa Barbara (-12.5%), San Martin (-11.0%) and Charcas (-8.5%) mines.

Operating Cash Costs: An overall benchmark that we use, which is a common industry metric to measure performance is operating cash costs per pound of copper produced. Operating cash cost is a non-GAAP measure that does not have a standardized meaning and may not be comparable to similarly titled measures provided by other companies. This non-GAAP information should not be considered in isolation or as substitute for measures of performance determined in accordance with GAAP. A reconciliation of our operating cash cost per pound of copper produced to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the consolidated statement of earnings is presented under the subheading, "Non-GAAP Information Reconciliation" on page 53. We disclose operating cash cost per pound of copper produced, both before and net of by-product revenues.

We define operating cash cost per pound of copper produced before by-product revenues as cost of sales (exclusive of depreciation, amortization and depletion), plus selling, general and administrative charges, treatment and refining charges net of sales premiums; less the cost of purchased concentrates, workers' participation and other miscellaneous charges, including royalty charges, and the change in inventory levels; divided by total pounds of copper produced by our own mines.

In our calculation of operating cash cost per pound of copper produced, we exclude depreciation, amortization and depletion, which are considered non-cash expenses. Exploration is considered a discretionary expenditure and is also excluded. Workers' participation provisions are determined on the basis of pre-tax earnings and are also excluded. Additional exclusions from operating cash costs are items of a non-recurring nature and the mining royalty charge as it is based on various calculations of taxable income, depending on which jurisdiction, Peru or Mexico, is imposing the charge. We believe these adjustments allow our management and stakeholders to more fully visualize our controllable cash cost, which we believe is one of the lowest of all copper-producing companies of similar size.

We define operating cash cost per pound of copper produced net of by-product revenues as operating cash cost per pound of copper produced, as defined in the previous paragraph, less by-product revenues and net revenue (loss) on sale of metal purchased from third parties.



                                       40

Table of Contents

In our calculation of operating cash cost per pound of copper produced, net of by-product revenues, we credit against our costs the revenues from the sale of all our by-products, including, molybdenum, zinc, silver, gold, etc. and the net revenue (loss) on sale of metals purchased from third parties. We disclose this measure including the by-product revenues in this way because we consider our principal business to be the production and sale of copper. As part of our copper production process, much of our by-products are recovered. These by-products, as well as the processing of copper purchased from third parties, are a supplemental part of our production process and their sales value contribute to covering part of our incurred fixed costs. We believe that our Company is viewed by the investment community as a copper company, and is valued, in large part, by the investment community's view of the copper market and our ability to produce copper at a reasonable cost.

We believe that both of these measures are useful tools for our management and our stakeholders. Our cash costs before by-product revenues allow us to monitor our cost structure and address areas of concern within operating management. The measure operating cash cost per pound of copper produced net of by-product revenues is a common measure used in the copper industry and is a useful management tool that allows us to track our performance and better allocate our resources. This measure is also used in our investment project evaluation process to determine a project's potential contribution to our operations, its competitiveness and its relative strength in different price scenarios. The expected contribution of by-products is generally a significant factor used by the copper industry to determine whether to move forward or not in the development of a new mining project. As the price of our by-product commodities can have significant fluctuations from period to period, the value of its contribution to our costs can be volatile.

Our operating cash cost per pound of copper produced, before and net of by-product revenues, is presented in the table below for the three months ended March 31, 2022 and 2021:

measure.

(2) Net of metallurgical losses.

As seen in the table above, our per pound cash cost before by-product revenues in the first quarter of 2022 was 21.2% higher than in the same period of 2021. This increase was mainly attributable to an increase in production costs. Our cash cost per pound net of by-product revenue for the first quarter of 2021 decreased 25.7% when compared to the same period of 2021. This was mainly attributable to a significant increase in by-product revenues.

Metal Prices: The profitability of our operations is dependent on, and our financial performance is significantly affected by, the international market prices for the products we produce, and for copper, molybdenum, zinc and silver in particular.

We are subject to market risks arising from the volatility of copper and other metal prices. For the remaining nine months of 2022, assuming that expected metal production and sales are achieved, tax rates remain unchanged and no

Change in net earnings (in millions) $ 85.2 $ 24.5 $ 10.8 $ 8.5

Business Segments: We view our Company as having three reportable segments and manage it on the basis of these segments. These segments are (1) our Peruvian operations, (2) our Mexican open-pit operations and (3) our Mexican underground operations, known as our IMMSA unit. Our Peruvian operations include the Toquepala and Cuajone mine complexes and the smelting and refining plants, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with significant by-product production of molybdenum, silver and other material. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities, which service both mines. The Mexican open pit operations produce copper, with significant by-product production of molybdenum, silver and other material. Our IMMSA unit includes five underground mines that produce zinc, lead, copper, silver and gold, and several industrial processing facilities for zinc, copper and silver.

Segment information is included in our review of "Results of Operations" in this item and also in Note 14 "Segment and Related Information" of our condensed consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Sol and the Mexican Peso: Our functional currency is the U.S. dollar and our revenues are primarily denominated in U.S. dollars. Significant portions of our operating costs are denominated in Peruvian sol and Mexican pesos. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency and Mexican currency occur, our operating results can be affected. In recent years, we believe such changes have not had a material effect on our results and financial position. Please see Item 3. "Quantitative and Qualitative Disclosures about Market Risk" for more detailed information.

Capital Investment Programs: We made capital investments of $205.2 million in the three months ended March 31, 2022, compared to $232.6 million in the same period of 2021. In general, the capital investments and investment projects described below are intended to increase production, decrease costs or address social and environmental commitments.

Set forth below are descriptions of some of our current expected capital investment programs. We expect to meet the cash requirements for these projects by utilizing cash on hand; internally generated funds and additional external financing, including funding received in September 2019. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy, market conditions or the COVID-19 pandemic.

Projects in Mexico:

Buenavista Zinc - Sonora: This project is located within the Buenavista facility and includes the development of a new concentrator to produce approximately 100,000 tonnes of zinc and 20,000 tonnes of copper per year. We have completed the engineering study. In order to continue with the project, stronger preventive measures to combat COVID-19 have been put in place. Procurement has progressed 99% and all the main equipment is on site. Construction site works are in progress. The project has all the necessary permits. The project´s budget is $413 million, and we expect to initiate operations in the second half of 2023. As of March 31, 2022, we had invested $240.5 million in this project. When completed, we anticipate that this new facility will double the Company's zinc production capacity and will provide 490 direct jobs and 1,470 indirect jobs.

Pilares - Sonora: Located six kilometers from La Caridad, this project consists of an open-pit mine operation with an annual production capacity of 35,000 tonnes of copper in concentrate. A new 25-meter wide off-road facility for mining trucks has been built and will be used to transport the ore from the pit to the primary crushers at the La Caridad copper concentrator. This project will significantly improve the overall mineral ore grade (combining the 0.78% expected from Pilares with 0.34% from La Caridad). The budget for Pilares is $159 million of which we have invested $79.5 million as



                                       42

of March 31, 2022. The project has obtained all permits and licenses required and we expect to begin production in the last quarter of 2022.

El Pilar - Sonora: This low-capital intensity copper greenfield project is strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 317 million tonnes of ore with an average copper grade of 0.249%. We anticipate that El Pilar will operate as a conventional open-pit mine with an annual production capacity of 36,000 tonnes of copper cathodes. This operation will use highly cost efficient and environmentally friendly SX-EW technology. We estimate a development investment of approximately $310 million. The results from experimental pads in leaching process have confirmed adequate levels of copper recovery. We expect this project to start production in 2024 with an expected mine life of 13 years. The basic engineering study is finished and the Company continues developing project and site environmental activities.

Lime plant - Sonora: As part of our cost improvement projects, we are building a new lime plant with a production capacity of 600 metric tonnes per day, which will be the largest lime plant of Mexico. This facility will allow us to reduce to approximately 50% our current lime cost at our Mexican operations. The total budget for the plant is $63.1 million, of which we have spent $46.2 million as of March 31, 2022. We expect this project initiate operations in the third quarter of 2022.

Projects in Peru:

Quebrada Honda dam expansion - Tacna: This project aims to enlarge the main and lateral dams in Quebrada Honda and includes the relocation and repowered of some facilities due to dam growth and implementation of other facilities for water recovery, among other factors. As of March 31, 2022, pre-commissioning and commissioning activities are in progress with work on three fronts. This project has a total budget of $179.4 million, of which we have invested $146.2 million as of March 31, 2022.

Tia Maria - Arequipa: On July 8, 2019, we were granted the construction permit for this 120,000 tonne annual SX-EW copper greenfield project with a total capital budget of $1,400 million. The Government awarded the permit after completing an exhaustive review process, complying with all established regulatory requirements and addressing all observations raised. The challenges surrounding the construction permit were overcome when on October 30, 2019, the Mining Council of the Peruvian Ministry of Energy and Mines ratified the construction permit for the Tia Maria project.

The Company has been consistently working to promote the welfare of the Islay province population. As part of these efforts, we have implemented successful social programs in education, healthcare and productive development to improve the quality-of-life in the region. We also have promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

In 2021, SPCC fortified its relation with the regional government and successfully overcame its opposition to project initiation. This new consensus was reflected in an agreement for "works for taxes" for projects relative to health facilities and roads. Our efforts to ensure the current and long-term welfare of the population in the area of influence of the Tia Maria project were recognized by several local associations, which sent letters to the National Government to request project initiation.

We reiterate our view that the initiation of construction activities at Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. During the construction and operation phase, we will make it a priority to hire local labor to fill the 9,000 jobs (3,600 direct and 5,400 indirect) that we expect to generate during Tia Maria's construction phase. When operating, we expect Tia Maria to directly employ 600 workers and indirectly provide jobs for another 4,200. Additionally, from day one of our operations, we will generate significant contributions to revenues in the Arequipa region via royalties and taxes.

We expect the Peruvian government to continue to acknowledge the significant progress the project has made on the social front and the important contributions that Tia Maria will generate for Peru´s economy and, consequently, take the necessary steps to provide SCC with adequate support to initiate construction.

This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry due to their technical process with no emissions released into the atmosphere.

Potential projects

We have a number of other projects that we may develop in the future. We continuously evaluate new projects on the basis of our long-term corporate objectives, expected return on investment, environmental concerns, required investment and estimated production, among other considerations. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy, market conditions or the COVID-19 pandemic.

El Arco - Baja California: This is a world-class copper deposit located in the central part of the Baja California peninsula with ore reserves of over 1, 230 million tonnes with an average ore grade of 0.40% and 141 million tonnes of leach material with an ore grade of 0.27%. The project includes an open-pit mine with a combined concentrator and SX-EW operations. Annual production is expected to total 190,000 tonnes of copper and 105,000 ounces of gold with an estimated capital budget of $2.9 billion. The Company has started the baseline study and is reviewing the basic engineering analysis to request the environmental impact permit. Several years back, we began to acquire the rights to all relevant mining concessions in the area; this process was completed in 2020.

Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates of indicated copper mineral resources are 98 million tonnes of oxides with a copper content of

0.45% and 52 million tonnes of sulfides with a copper content of 0.59%. Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 130,000 tonnes of copper and 7,500 tonnes of molybdenum anually. The estimated capital investment is $2,600 million and the project is expected to be in operation in 2027. In the first quarter of 2022, we continued to engage in social and environmental improvements for the local communities and we worked on the environmental impact assessment for the project.

Michiquillay Project - Cajamarca: On June 12, 2018, Southern Copper signed a contract and made an initial payment of $12.5 million for the acquisition of the Michiquillay project in Cajamarca, Peru. In June 2021, the Company paid an additional $12.5 million to acquire the project. The Company has created a multidisciplinary management team to plan the development of this project. As part of this plan, the Company has established venues of contact with the local and regional authorities and communities to promote programs for the sustainable development in the area. On September 3, 2021, the Company signed a Social Agreement with the Michiquillay Community and on November 12, 2021, the Company signed a Social Agreement with the Encañada Community. Additionally, on October 1, 2021 the Peruvian Ministry of Energy and Mines approved the semi-detailed Environmental Impact Study for the project.

The Social Agreements with the Michiquillay and the Encañada communities represent an opportunity to improve the quality of life of the residents of those communities via our strong social programs and backed by a solid framework for technical work at the project level. These events are important steps that will allow Southern Copper to initiate an in-depth exploration program in the second quarter of 2022.

Michiquillay is a world class mining project with inferred mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. When developed, we expect Michiquillay to produce 225,000 tonnes of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years, at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2028 and that Michiquillay will become one of Peru´s largest copper mines. The project will create significant business opportunities in the Cajamarca region; generate new jobs for the local communities and contribute with taxes and royalties to the local, regional and national governments.

The above information is based on estimates only. We cannot make any assurances that we will undertake any of these projects or that the information noted is accurate.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE ("ESG")

In line with our sustainability strategy, we registered on-going improvement in our main sustainability indicators. In terms of safety, we reduced the accident rate of our own personnel and contractors by 22% in the last three years. With reference to the main environmental indicators, our Scope 1 and 2 greenhouse gas emissions have been reduced by more than 10%, while the efficiency in the consumption of fresh water in the concentrators has increased by 4% over the period. Regarding social matters, the population served through our community programs has tripled, while we continue to strengthen the mechanisms for listening and addressing their concerns.

In an effort to provide certainty to our investors and stakeholders, we present our progress regarding third-party validation of our environmental and social practices. We continue with the process of certifying our occupational health and safety management systems under the international standard ISO 45001 and our environmental management systems under ISO 14001 at all of our mining units. In the first quarter of 2022, the Santa Barbara and San Martin mines received an ISO 45001 certification and the La Caridad Mine and the Lime Plant in Sonora, received an ISO 14001 certification.

Regarding our climate change management, the company is now positioned above average for the sector and region, in view of the fact that Grupo Mexico rose two levels, from level C to level B, in the evaluation of the Carbon Disclosure Project (CDP) in 2021.

The communities surrounding our operations in Peru consist of dozens of small towns that live from the high Andean desert region to the Pacific coast. We continue to address the challenges and needs of these communities including water supply, education and employment. Investments in infrastructure for water supply are noteworthy, representing 70% of the $93.6 million invested in the last ten years. In the first quarter of 2022, the construction of the Cularjahuira dam in the province of Candarave, in the area of influence of our Toquepala mine, was completed; which will store up to 2.55 million cubic meters of water to irrigate 500 hectares of agricultural land and will directly benefit 585 families of local farmers.

ACCOUNTING ESTIMATES

Our discussion and analysis of financial condition and results of operations, as well as quantitative and qualitative disclosures about market risks, are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Preparation of these consolidated financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We make our best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: ore reserves, revenue recognition, ore stockpiles on leach pads and related amortization, estimated impairment of assets, asset retirement obligations, determination of discount rates related to the financial lease liabilities, classification of operating leases versus financial leases, valuation allowances for deferred tax assets, unrecognized tax benefits and fair value of financial instruments. We base our estimates on historical experience and on various other assumptions that we believe reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.
