October 27, 2014 - Southern Copper Corporation (NYSE and BVL: SCCO)

Third quarter 2014 ("3Q14") net sales were $1,474.6 million,

6.5% higher than 3Q13 net sales of $1,384.5 million due to
better volumes.

EBITDAi in 3Q14 was $675.7 million, 1.6% lower than the $686.8 million in 3Q13. Margin decreased from 49.6% to

45.8% mainly due to the higher cost of inputs such as fuel, tires and water.

Net income in 3Q14 was $324.3 million (22.0% of net sales), 5.8% lower than the net income of $344.2 million (24.9% of net sales) in the 3Q13. Net Income in the nine months of 2014 ("9M14") was $985.0 million. Net income this year has decreased in $65 million due to the new special tax on mining in Mexico.

Copper production increased 4.7% from 160,602 metric tons in 3Q13 to 168,210 metric tons in 3Q14. Molybdenum production increased by 26.9% in 3Q14 compared with 3Q13. This increase was the result of greater production from our Buenavista and Toquepala operations.

Operating cash costii per pound of copper before by-product credits was $1.96 in 3Q14, a 4.8% increase compared to 3Q13. Operating cash cost per pound of copper net of by-product credits was $1.14 in 3Q14.

Capital expenditures for the 9M14 were $1,111 million, which in addition to the approximately $600 million already committed, we have reached 74% of our budget of $2.3 billion for 2014.

Tia Maria Project: On August 1, 2014, we received the final approval of our Environmental Impact Assessment (EIA). We expect to be granted the authorization to move forward with the construction phase before the end of the year and begin construction in the 1Q15. This project will produce 120,000 tons of copper cathodes per year and will be completed in 1Q17.

Accident in Leaching Dam under Construction: On August 6, 2014, an accidental spill of approximately 40,000 cubic meters of copper sulfate solution occurred at a leaching pond that was under construction ten kilometers away from the Buenavista mine. The accident was caused by a rock collapse that affected the system's pumping station and by a construction defect in the seal of a pipe in the leaching system containment dam, a part of the new SX/EW III plant. This solution reached the Bacanuchi River, a branch of the Sonora River.

We commissioned more than 1,210 people to attend the local communities work on the cleanup of the 250 kilometers of the Bacanuchi and Sonora riverbeds, which has been successfully completed.
We established a 2 billion peso (approximately $150 million) trust fund to support remedial actions and provide compensation for those affected by this accident. A technical committee was created to manage the funds, comprised of representatives from the federal government, the Company and specialists assisted by a team of environmental experts.

THIRD QUARTER AND NINE MONTHS 2014 RESULTS SOUTHERN COPPER


The authorities have determined that all the wells for agriculture and domestic use that were preventively closed can be reopened because the official water test results comply with all applicable norms and regulations.
The Company created a website with the latest news of all actions taken to mitigate and remediate the Sonora River accident: www.riosonora.com.mx

Dividends: On October 23, 2014, the Board of Directors authorized a dividend of $0.12 per share payable on

November 25, 2014, to shareholders of record at the close of business on November 11, 2014.
Commenting on the quarter, Mr. German Larrea, Chairman of the Board, said "The Company investment program is
yielding its first results through higher copper and molybdenum production. Mined copper production has increased by
9% in the nine months of 2014 while molybdenum by 24% in the same period. These encouraging results are mainly the consequence of our aggressive investment program which aims to increase copper production by 87% from its
2013 level to over 1.2 million tons of capacity by 2017. I believe the positive results of our capital program will be of great benefit for our stockholders, labor force, government and other constituencies of Southern Copper".

Capital Expenditures

The current status of our major capital expenditure projects as of September 30, 2014, is the following:

Mexican Projects

Buenavista Projects: We continue developing our $3.4 billion investment program at this unit which is expected to increase its copper production capacity by approximately 175%, as well as molybdenum production by 42%.

Mine Expansion: to date we have received sixty-one 400-tons capacity trucks, seven shovels and eight drills required for the mine expansion; with an investment of $510.8 million. All of this equipment is currently in operation.

The new Copper Molybdenum Concentrator has an annual production capacity of 188,000 tons of copper and 2,600 tons of molybdenum. The project will additionally produce 2.3 million ounces of silver and 21,000 ounces of gold per

year. The project has an 86.4% progress with an investment of $882.6 million out of the approved capital budget of
$1,383.6 million. The project is expected to be completed in the 3Q15. All major equipment is on site and has been installed.

SXEW III Plant: we continue to ramp-up production since the first copper cathode was produced last June. All three Solvent Extraction trains are in operation, and we recently initiated operation of the second half of our Electro Winning Plant. Estimated annual production for the plant is 120,000 tons of copper cathodes. We expect to reach full capacity by the end of 4Q14 (adjusted from 3Q14 previously reported before the Sonora River accident). Capital budget of $444.0 million has been invested.

Crushing, Conveying and Spreading System for Leachable Ore (Quebalix IV): This project main objective is to reduce processing time and mining and hauling costs, and it will also increase production by improving SXEW copper recovery. It has a crushing and conveying capacity of 80 million tons per year and is expected to be completed in the

4Q15. The project has a 42.3% progress with an investment of $93.2 million out of the approved capital budget of $340 million.

Peruvian Projects

Toquepala Projects: Through September 30, 2014, we have invested a total of $324.9 million in Toquepala projects. On September 25, 2014, we answered the questions and comments received from authorities and other stakeholders related to the EIA of the Toquepala concentrator expansion. We expect to receive governmental approval of the EIA in the last quarter of 2014, which will allow us to continue developing this important project. The Toquepala concentrator expansion will increase annual production capacity by 100,000 tons of copper and 3,100 tons of molybdenum at a total capital cost of approximately $1.2 billion.

Cuajone Projects: Through September 30, 2014, we have invested and committed $39.2 million of a budget of $45 million on the HPGR project, which will produce a more finely crushed material. This project continues in the ramping up stage and we expect to reach full capacity during the fourth quarter of 2014. The project is expected to generate cost savings, improve copper recovery and reduce power consumption in the crushing process. Through September 2014, the implementation of the HPGR project and the variable cut-off ore grade project, implemented in 2013, have produced an estimated incremental production of 18,000 tons of copper.

The project to improve slope stability at the south area of the Cuajone mine will remove approximately 148 million tons of waste material. This project will improve mine design without reducing current production level. The mine equipment acquired includes one shovel, five 400-ton capacity trucks, one drill and auxiliary equipment which will be reallocated to our mine operations once the project is finished. Besides preparing the mine for the future, this investment will avoid a reduction in average ore grade. As of September 30, 2014, 7 million tons of waste material have been removed and activities will continue for 4.5 additional years. As of September 30, 2014, we have invested $66.7 million in this project.

Tia Maria Project: The project will represent an investment of approximately $1.4 billion to produce 120,000 tons of copper cathodes per year using state of the art technology with the highest international environmental standards. The project is currently expected to generate 3,500 jobs during the construction phase. When in operation, Tia Maria will directly employ 600 workers and indirectly another 2,000. Through its expected twenty-years of life, the project related services would create significant business opportunities in the Arequipa region.

In addition, the Company intends to implement social responsibility programs in the Arequipa region similar to those established in the communities near its other Peruvian operations.
