RESULTS SECOND QUARTER AND SIX MONTHS 2019 Investor Relations: Raul Jacob +(602) 264-1375 July 23, 2019 Southern Copper Corporation (NYSE and BVL: SCCO) southerncopper@southernperu.com.pe www.southerncoppercorp.com Copper production increased 16.5% to 256,352 tons in 2Q19 compared with 2Q18 due to higher production at our Peruvian Toquepala mine (+67.6%) and our Buenavista mine (+11.4%) in Mexico. These increases were partially offset by lower production at our Cuajone mine (-7.3%) due to lower grades and recoveries. Copper production increased 14.2% in the 6M19 when compared with 6M18 as result of higher production at Toquepala (+53.8%), due to the successful ramping up of the Toquepala concentrator; and higher production at Buenavista (+8.9%), due to operating improvements at its SX-EW (+30.5%) and concentrator (+7.0%) plants. 2Q19 net sales were $1,818.0 million. Copper sales volume increased (+11.7%) as well as molybdenum (+24.5%). However, due to lower metal prices of copper (-11.2% LME) and silver (-10.0%); net sales decreased by 1.0% when compared with 2Q18. 2Q19 net income was $402.4 million, 1.8% lower than 2Q18 net income of $409.6 million. Net income margin in 2Q19 was 22.1% compared with 22.3% in 2Q18. The decrease was principally due to lower sales prices. 2Q19 adjusted EBITDA was $942.8 million, 1.3% lower than 2Q18 adjusted EBITDA of $955.2 million. The adjusted EBITDA margin in 2Q19 was 51.9% compared with 52.0% in 2Q18. These decreases were mainly due to lower prices. By-product production: Molybdenum production increased (+24.7%) in 2Q19 compared with 2Q18 due to higher production at all our mines, particularly Toquepala (+94.5%) as result of the new molybdenum plant that started production in April 2019. Mined silver production increased by 5.3% in 2Q19 compared with 2Q18 due to higher production at Toquepala, which was partially offset by lower production at the Cuajone, La Caridad and IMMSA operations. Mined zinc production decreased 1.3% in 2Q19, compared with 2Q18 production due to lower production at the Charcas and Santa Eulalia mines which offset the 1,133 tons production increase at the San Martin mine. Operating cash cost per pound of copper including by-product revenues credit was $0.81 in 2Q19, an improvement of 11% compared to $0.90 in 1Q19. This cost decrease is mainly due to the unit cost effect of 12.2% higher copper production. Capital investments in 6M19 were $353.5 million. These investments are in line with our growth program aiming to produce 1.5 million tons of copper by 2025. Dividends: On July 18, 2019, the Board of Directors authorized a dividend of $0.40 per share payable on August 22, 2019, to shareholders of record at the close of business on August 8, 2019.

Guaymas sulfuric acid spill: On July 9, at our Marine Terminal in Guaymas, Sonora, there was an incident that caused the discharge of approximately 3 cubic meters of sulfuric acid into the sea in the industrial port area. The Guaymas bay has an estimated water volume of 340 million cubic meters, the spill upon entering in contact with the sea’s alkaline conditions, the discharge was quickly diluted and the sulfuric acid was naturally and immediately neutralized. As a result the discharge was considered harmless, and it was found that neither the flora nor fauna of the port area were affected, according to the report from the Ministry of Navy. On July 10, the Mexican environmental protection agency (“PROFEPA”) made a first inspection of the area, concluding that the Company executed all the correct procedures in order to contain the discharge, and no reference was made to the existence of negative impacts on the environment resulting from the incident. On Friday, July 19, PROFEPA revisited the facilities to carry out a second inspection, declaring a partial temporary shutdown related only to the storage process and transportation of sulfuric acid at the terminal, arguing the absence of an authorization of environmental impact. It is important to note that these facilities have been in operation since 1979, previous to the 1988 Mexican General Law of Ecological Balance and the Protection of the Environment. Therefore, these licenses are not a requirement for companies that have being operating before the mentioned law. In addition, PROFEPA’s awarded in 2009 a certification of “Clean Industry and Environmental Quality” for such facility; which was subsequently renewed four times (for periods of two years each). We do not know the reasons or causes for this partial and temporary closure, but we will continue contributing with the environmental authorities with all the necessary elements in order to provide certainty with respect to the operation, in strict adherence to environmental regulations. We expect the environmental authorities to revoke the partial temporary shutdown, once they clarify their concerns. At this point, we do not expect any impact on our operations, as this terminal has no scheduled shipments until late August. Mr. German Larrea, Chairman of the Board, commenting on the Company´s progress said: “I am pleased to announce that on July 8, 2019, the Company received the construction license for the Tia Maria project. We strongly believe this $1.4 billion project will further improve the Company's asset base and profitability with an increase of 120,000 tons of annual copper production capacity at a very competitive cash cost. We think Tia Maria will also benefit Peru through multiple business and employment opportunities at a national, regional and local level, and with royalties and taxes. On top of this, with sales estimated at $750 million, Tia Maria will improve Peru´s economy with a 0.4% increase in its GDP." “This good news, gives us the confidence to continue our efforts on our $6.7 billion greenfield Peruvian investment program, which includes Tia Maria, with an investment of $1.4 billion, Los Chancas with $2.8 billion, and Michiquillay projects with $2.5 billion.

Capital Investments Southern Copper’s investment philosophy is not based on the outlook of copper prices but on the quality of the assets that we operate and develop. Throughout the years, our strong financial discipline has consistently allowed us to invest on a continuous basis in our superior asset portfolio. Peruvian Projects Currently we have a portfolio of $2.8 billion approved projects in Peru of which $1.8 billion have already been invested. Considering the Michiquillay ($2.5 billion) and Los Chancas ($2.8 billion) projects, our total investment program in Peru increases to $8.1 billion. Toquepala Expansion Project – Tacna: This $1.3 billion project includes a new-state-of-the-art concentrator that has increased Toquepala´s annual copper production to reach 258,000 tons in 2019, a 52% production increase for this operation when compared to 2018. As of June 30, 2019, we have invested $1,291.6 million in this expansion. The construction of the project was completed and production initiated in the 4Q18. Full production was reached in the 2Q19. Tia Maria - Arequipa: As mentioned above, on July 8, 2019 we have been granted the construction permit for this 120,000 ton annual SX-EW copper greenfield project with a total capital budget of $1,400 million. This permit was obtained after completing an exhausting review process, complying with all established regulatory requirements and addressing all observations raised. We guarantee to the population of Islay that the Tia Maria project will not adversely affect other local economic activities because we will use desalinated seawater for our operations and, for the transport of our supplies and copper production, we will build an 32 kilometer industrial railway and an access road at a safe distance from the Tambo Valley. We reiterate our commitment to delay the construction of the project until it has established, in coordination with the government, a common ground for dialogue with the neighboring communities to address any concerns and provide assurances to achieve more social support for the project. Meanwhile, we will continue to work for the welfare of the local population. Our social programs in education, healthcare and productive development will continue to improve the quality-of-life, and the agricultural and livestock activities in the Tambo Valley, as well as fishing and tourism in Islay. During the construction and operation phase, hiring local labor will be a priority. For this purpose, we have successfully launched in June the free technical training program “Forging the Future”, which will benefit 700 persons in this province in 2019-20. After training, the participants will be eligible to apply for one of the estimated 9,000 jobs (3,600 direct and 5,400 indirect) required during the Tia Maria construction phase. We strongly believe that the initiation of construction activities for Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. When in operation, we expect Tia Maria will generate a significant contribution through mining royalties and taxes from day-one and will directly employ 600 workers and indirectly provide jobs for another 4,200. Mexican Projects Buenavista Zinc - Sonora: This project is located within the Buenavista facility and includes the development of a new concentrator to produce approximately 80,000 tons of zinc and 20,000 tons of copper per year. Currently, we have completed the basic engineering. Environmental studies are in process. The project´s budget is $413 million, and we expect to initiate operations in 4Q21. When completed, 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 6 kilometers from La Caridad, this project consists of an open-pit mine operation with an annual production capacity of 35,000 tons of copper in concentrates. The ore will be transported from the pit to the primary crushers of the La Caridad copper concentrator via a new 25-meter wide off-road facility for mining trucks. 2Q19 www.southerncoppercorp.com Page 3 of 10 SECOND QUARTER AND SIX MONTHS 2019 RESULTS SOUTHERN COPPER

Environmental permits have been obtained and additional land is being acquired. This project will significantly improve the over-all mineral ore grade (combining the 0.78% expected from Pilares with the 0.34% from La Caridad). The budget for Pilares is $159 million and we expect it to start production during the second half of 2020. Conference Call The Company’s second quarter earnings conference call will be held on Wednesday, July 24, 2019, beginning at 10:00 AM – EST (9:00 AM Lima and Mexico City time).

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.
