·

Copper production was slightly lower than in 3Q22 in quarter-on-quarter terms and stood at 226,120 tons. The decrease in production at our Peruvian operations (-2.1%) was mainly driven by our Cuajone mine, which reported lower ore grades; this was partially offset by higher production at Toquepala mine due to better ore grades. Production at our Mexican operations decreased 1.8% in a quarter-on-quarter terms mainly due to lower production at our Buenavista mine (-2.5%). On a YoY basis, copper production rose 3.6% in 2023 to stand at 676,925 tons, which reflected higher production at our Peruvian operations.

·

By-product production: Molybdenum production increased (+12.6%) in 3Q23 compared to 3Q22 due to higher production at the Toquepala, Buenavista and La Caridad mines. Mined zinc production rose 9.4% this quarter due to higher production at the Charcas and Santa Barbara units, which was mainly attributable to an increase in processed material. These results were partially offset by lower production at the San Martin mine due to lower ore milled. Mined silver production registered a decrease of 10% in 3Q23, which was driven by reductions at all our operations, with the exception of our Toquepala mine. On a YoY basis, zinc and molybdenum production were up 8.6% and 0.8% respectively compared to 2022. Silver production remained at the same level.

·

Operating cash cost per pound of copper, including by-product revenue credits, was $0.98 in 3Q23, which represented a decrease of 12.4% compared to the $1.12 reported in 2Q23.

Capital Investments

Our current capital investment program for this decade exceeds $15 billion and includes investments in the Buenavista Zinc, Pilares, El Pilar and El Arco projects in Mexico and in the Tia Maria, Los Chancas and Michiquillay projects in Peru. This capital forecast includes several infrastructure investments, including key investments to bolster the competitiveness of the El Arco project.

Projects in Mexico:

Buenavista Zinc - Sonora: This project is located in Cananea, Sonora within the Buenavista deposit, where we have built a new concentrator plant. This facility has a production capacity of 100,000 tonnes of zinc and 20,000 tonnes of copper per year. When operating, the concentrator will double the Company's zinc production capacity and will provide more than 2,000 jobs on the operating front.

Project update: the capital budget for the project is $413 million, most of which has already been invested. Progress is 99%; we have initiated the commissioning process. The ramping up of the plant, initially scheduled to conclude in 4Q23, has been pushed back to 1Q24 given that the concentrator requires technical adjustments.

Pilares - Sonora: Located six kilometers from La Caridad, this is actually an open-pit mine operation with an annual production capacity of 35,000 tonnes of copper in concentrate. This will significantly improve the overall mineral ore grade (considering the 0.78% expected from Pilares with 0.29% from La Caridad).

Project update: The budget for Pilares is $176 million, of which $144 million has been invested. Pilares is currently operating and delivering copper ore to the Caridad operation.

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. The budget for El Pilar is $310 million.

Project update: The results from experimental pads in the leaching process have confirmed adequate levels of copper recovery and we are evaluating different options to improve the same. The basic engineering study has been completed and the Company is engaging in project development and onsite environmental activities. Project engineering is being developed by an external engineering and technology company. Mine life is estimated at 13 years.

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 average 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.

Project update: The Company has completed the environmental baseline study for the mine, concentrator and industrial facilities and will proceed to submit the Environmental Impact Statement (Manifestacion de Impacto Ambiental "MIA") to the Secretary of Environment and Natural Resources "SEMARNAT" to request the respective environmental impact permits. The Company is currently preparing studies for the port, power lines, townsites and auxiliary facilities.

Projects in Peru:

Tia Maria - Arequipa: This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards to produce 120,000 tons of SX- EW copper cathodes per year. The estimated capital budget for the project is $1.4 billion.

Southern Copper has been consistently working to promote the welfare of the population of the Islay province. 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 have also promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

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. Given the current Peruvian economic situation, it is crucial to move ahead on projects that will stimulate a sustainable growth cycle. We will make it a priority to hire local labor to fill the 9,000 jobs that we expect to generate during Tia Maria's construction. Additionally, from day one of our operations, we will generate significant contributions to revenues in the Arequipa region.

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 tons of oxides with a copper content of 0.45% and 52 million tons of sulfides with a copper content of 0.59%. The Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 130,000 tons of copper and 7,500 tons of molybdenum annually. The estimated capital investment is $2,600 million and the project is expected to begin operating in 2030. We continue to engage in social and environmental improvements for the local communities and work on the project's environmental impact assessment.

Project update: As of September 30, 2023 the Company has held talks with representatives of the Tiaparo Community to acquire part of the land required for the project. Simultaneously, we continue to work with the Peruvian authorities to eliminate illegal mining activities at our concession. SCC will initiate hydrogeological and geotechnical studies soon to gather additional information on the characteristics of the Los Chancas deposit.

Michiquillay Project - Cajamarca: In June 2018, Southern Copper signed a contract for the acquisition of the Michiquillay project in Cajamarca, Peru. Michiquillay is a world class mining project with inferred mineral resources of 2,288 million tons with an estimated copper grade of 0.43%. When developed, we expect Michiquillay to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years and at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2032. Michiquillay will become one of Peru's largest copper mines and 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.

Project update: In 2023, in accordance with our social agreements with the Michiquillay and La Encañada communities, the Company has hired unskilled labor and is paying for the use of surface land. We are also supporting social programs in both communities. Simultaneously, exploration activities are underway. As of September 30, 2023, we had drilled 46,500 meters and obtained 14,892 core samples, which are currently under evaluation.

Environmental, Social & Corporate Governance (ESG) Practices

Investments that transcend. We are building drinking water infrastructure to remedy shortages in Cananea and Nacozari communities in Sonora, Mexico; approximately 75 thousand residents will benefit from these initiatives. This effort is aligned with our policies and commitments for sustainable development and is part of the US$77 million that we have invested in Mexico and Peru over the last 5 years.

Innovation in the use and efficiency of water. We are currently recovering about 6 thousand cubic meters of water per day through the new tailings filtering plant in Quebrada Honda, Peru, which is equivalent to 0.6 m3 of water per ton of tailings. With a design capacity of 10,000 tons/day and an investment to date of $27 million, this dam filter is the largest tailings processing unit of its kind in the market.

Focus on prevention and risk management. In September 2023, our Buenavista del Cobre unit in Sonora received "Safe and Healthy Work Environments" ("ELSSA") recognition from the Mexican government after successfully passing an audit conducted by the Mexican Social Security Institute. All of our other Mexican units also hold this recognition, which is awarded to companies that implement effective strategies and preventive actions for occupational health and safety.

We continue to make progress with our Critical Risk Registry and the performance levels of the controls in place to prevent or mitigate undesirable events have improved. To achieve this, we have involved the heads of each operating unit in the process to establish and continuously monitor controls. All results are reported to managing executives on a monthly basis to facilitate supervision and subsequent monitoring by the Board of Directors.

Innovation in climate change mitigation. In September 2023, Southern Perú received the 2023 National Mining Award in the Mining Economy category within the framework of PERUMIN 36 Mining Convention held in Arequipa, Peru. The winning study "Integration scenarios of renewable electricity generation systems in the mining sector of Peru by 2050", prepared by Eng. Rolando Jesus Claros, from the Power System area, proposes the use of clean and renewable energy sources as part of the global energy transition process. Southern Copper aims to achieve net-zero emissions by 2050.

Disclosure, transparency, and accountability. To provide more clarity regarding Southern Copper's performance on ESG issues, we have published a supplement to the 2022 Sustainable Development Report and have also incorporated new topics on our sustainable development page to address biodiversity, our people, human rights and the supply chain.

At the behest of our investors, we have expanded our responses to the CDP questionnaires to include the "Forests" questionnaire. This information complements responses to our "Climate change" and "Water security" questionnaires, which have been available since 2016 and 2022 respectively.

From loss to gain: A journey of environmental restoration. Year to date, we have reforested 3 times the area impacted in the same period (1,398 hectares replanted versus 424 hectares impacted). Additionally, we have implemented works to retain 10,722 tons of soil that would have otherwise been lost to erosion in the state of Sonora, Mexico. These actions are within the framework of our strategy to achieve zero net deforestation and generate a net positive impact on biodiversity, particularly in areas close to our operations.

Harmony and human development in communities where we operate. Inhabitants of the communities near our operations are highly active in the social programs we offer. Thus far this year, we have recorded 170 thousand participations in these programs, which is a 7% increase from the previous year. One of our most noteworthy efforts, the Youth Orchestras and Choirs program, recently celebrated is fifth year in Nacozari de Garcia, Sonora and is now present in 11 communities with 1,596 students in Mexico and Perú. To date, 8 out of 10 of our alumni pursue a bachelor´s degree, with 2% choosing music as their life project.

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by U.S. generally accepted accounting principles ("GAAP"). These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. In addition, because not all companies use identical calculations, the measures included in this release may not be comparable to similarly titled measures of other companies. Following is a reconciliation of adjusted EBITDA to Net Income attributable to SCC and Operating Cash Cost before by-product revenues and Operating Cash Cost net of by-product revenues to their more comparable GAAP measure:

Adjusted EBITDA

EBITDA (earnings before interest, taxes, depreciation and amortization) is a measure commonly used by companies to evaluate operating performance and the ability to generate cash. Our adjusted EBITDA is not necessarily comparable to similar measures used by other companies. We believe that adjusted EBITDA provides useful information to management, investors and others in understanding and evaluating our operating results.

Our determination of the components of adjusted EBITDA is evaluated periodically based on a review of non-GAAP financial measures used by mining industry analysts. Management believes adjusted EBITDA enhances the comparability of information across reporting periods, is an effective measure for reviewing operating results and, therefore, is a useful measure for both management and investors. EBITDA and adjusted EBITDA do not represent, and should not be considered an alternative to, net income, operating income, or cash flow from operations as those terms are defined by GAAP, and do not necessarily indicate whether cash flows will be sufficient to fund cash.

Operating cash cost per pound of copper produced before by-product revenues and Operating cash cost per pound of copper produced net of by-product revenues

The measure operating cash cost per pound of copper produced net of by-product revenues is a common measure used in the copper industry to track performance and it is a useful management tool that allows us to 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 in determining whether to move forward with 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 by-product revenues allows us and our investors to monitor our cost structure and helps us address operating management areas of concern.
