First Quarter Results 2011

Mexico City. April 19, 2011 — Grupo México, S.A.B. de C.V. (“Grupo México” — BMV: GMEXICOB) reports its results for the first quarter 2011 (“1Q11”).

First Quarter 2011 Results

Highlights

Mining Division — Americas Mining Corporation (AMC)

	•		Minera México recognized as a Socially Responsible Company (SRC).- The Mexican Center for Philanthropy (Cemefi) awarded Minera México the SRC distinction, with which the company is committed to continuing to contribute to improving the quality of life and development of the communities where we operate.
	•		Combined Operations of Asarco and Southern Copper Corporation (SCC).- The Special Committee of Independent Directors, formed August 10, 2010 by SCC, continues to evaluate the AMC proposal to combine SCC and Asarco. GMéxico is convinced the combining of SCC and ASARCO will provide important synergies, including reductions in operating costs, transportation, and overhead, and also capital expenditure savings, which would benefit all shareholders of the new combined entity.
	•		Buenavista del Cobre.- During 1Q11, Buenavista produced 27,598 tons of copper: 14,964 tons of copper cathode at the SX/EW Plant and 12,634 tons of copper concentrate at the Concentrator Plant which is now operating at full capacity. Copper production is expected to increase in the remaining three quarters of 2011 when completing its optimization processes and increase the concentrator’s recovery to full copper production during the 2Q11. The current annual capacity of both plants is 180,000 tons.
			Construction continues to advance favorably on the two new leaching plans, SX/EW III and SX/EW IV, which will add a total of 88,000 tons of copper per year starting 2013; and also the construction of the crushing and haulage system at these plants. The detailed engineering is almost complete for the new concentrator at Buenavista with an annual production capacity of 188,000 tons of copper contained in concentrates, which will start operating in 2015. Construction also continues on the molybdenum benefit plant, with an annual capacity of 2,000 tons, which will start operating the fourth quarter of 2012.
			The implementation of community works and infrastructure, and health and education programs continues to benefit the surrounding area. In 2011, the Company plans to invest US$12 million in the community.
	•		Tía María Project.- Since March 23, 2011, a small group opposing the mine operations held violent demonstrations including blocking roadways, damaging public and private property, and confronting with police. In one specific incident, they blocked the high-traffic Pan-American Highway 50 kilometers away from our mine, which was not related in any manner to the construction of the project, rather it was merely an excuse to stop investment in Peru and cause problems for the state, companies, and the community.
			The Company has repeatedly stated that the water to be used for the project will be transported from the ocean through a 30 kilometer pipeline, after its desalinization. All tests have been conducted using sea water, making the falseness of the activists’ argument that water will be taken from farming all the more apparent. Regarding the other alleged pollution argument, the Company has proven that the project complies with the strictest environmental standards. These types of plants have been developed in Peru and other countries, complying to the fullest with environmental regulations and therefore do not pollute the soil, water, or air.
			The Peruvian government has suspended the Tía María project in light of the events mentioned. The Company will allow an appropriate amount of time to elapse because of the current political situation in Peru, although in the near future will provide the authorities with any information the Ministry of Energy and Mines (MEM) may request regarding the Environmental Impact

1Q11		www.gmexico.com		Page 2

First Quarter 2011 Results

			Assessment. The Company is confident that with this information any concerns the authorities might have will be answered in terms of compliance with the strictest environmental standards.
			The Tía María project represents an investment of approximately US$1.0 billion, which would generate important contributions to Peru’s economy significantly increasing exports and revenues from taxes, duties, and mining royalties, in addition to generating 4,000 jobs during the construction phase and 4,100 direct and indirect permanent jobs. The estimated annual production of the project is 120,000 tons of copper cathode through a leaching process, technology that is considered worldwide to be the most environmentally-friendly production method. In addition, the company plans to invest in community programs in the Arequipa region similar to those established in the neighboring communities to the current operations at Toquepala, Cuajone, and Ilo in Peru.
			The Company is confident the Peruvian government will provide the legal stability that allows for economic development and mining investments in Peru, with the legal certainty needed for growth and development.
	•		Copper Hedging.- Taking advantage of record high copper prices and to reduce revenue volatility, the Mining Division has engaged copper hedging to benefit from the current copper prices for a percentage of its production while protecting against drops for a lesser percentage. For the remainder of 2011, AMC engaged swaps for nearly 36% of its estimated production at an average price of US$3.98 and zero cost collars for nearly 36% with a floor price of US$3.10 and cap of US$4.73, while the remaining production will fluctuate according to market prices. For 2012, AMC has zero cost collars for 5% of its estimated production with a floor price of US$3.50 and cap of US$5.20.

Transportation Division

	•		The acquisition of Ferrosur received final approval.- Final decision was handed down allowing the Transportation Division to consolidate Ferrosur’s results with ITM, finding there to be no concentration and therefore no monopolistic practices, as the Federal Competition Bureau (CFC) had claimed. With this decision, the Transportation Division will obtain highly significant synergies in operating methods and sales.
			On March 25, 2011, the First Collegiate Court found to dismiss the appeal brought by the CFC against the decision of the Federal Court of Justice on Tax and Administrative Matters (TFJFA) in favor of Infraestructura y Transportes México (ITM) and Infraestructura y Transportes Ferroviarios (ITF), subsidiaries of GMéxico. No further recourse may be admitted against the TFJFA decision.
	•		Debt Issued.- On April 15, 2011, Ferromex placed 10 year notes for $1.5 billion pesos at a fixed rate of 8.88%. These resources will be allocated primarily to finance the purchase of 44 new locomotives.
	•		Ferromex.- During el 1Q11, Ferromex continued to report excellent operating performance. Sales increased 16.3% over the previous quarter, to reach US$305 million. The operating profit and EBITDA were US$59 million and US$83 million, respectively, representing an increase over that posted for the previous quarter.
			In terms of volume transported, the net tons/km increased 3% and loaded cars 7.6%, when compared to 1Q10, to 10.746 billion net tons/km and 204,000 cars. The main increases were seen in the intermodal segment, reporting a 33% increase in net tons/km and 22% in cars, and also the mineral segment increased net tons/km by 13.5% and cars by 29%.

1Q11		www.gmexico.com		Page 3

First Quarter 2011 Results

	•		Ferrosur.- During 1Q11, Ferrosur posted record figures. Sales were US$76.3 million, 20.1% above the US$63.5 million for 1Q10 and 7.5% over its record. The operating profit increased 42.5% when compared to the previous year, reaching US$15.8 million. The EBITDA reflected an increase of 31.3% to US$22.7 million, compared to US$17.3 million for the previous year.
			Ferrosur increased its net tons/km by 45% and loaded cars by 34% in the metals segment, and also net tons/km by 39% and loaded cars by 27% in the automotive segment.
	•		Capital Expenditures.- In 1Q11, the Railroad Division invested US$27.2 million to improve the infrastructure throughout its rail line, modernizing operating systems for greater safety and perfecting commercial systems. Capital expenditures for the Railroad Division in 2011 will be US$395.6 million, principally for the purchase of 58 locomotives (44 for Ferromex and 14 for Ferrosur), the construction and expansion of sidings, and infrastructure improvements.

Infrastructure Division

	•		Infrastructure Projects.- Taking advantage of its experience and human and technical resources, on April 1, the subsidiary México Constructora Industrial S.A. de C.V. was awarded a 30 year tender by the Department of Transport and Communications (SCT) to build, operate, exploit, maintain, and preserve the Salamanca-Leon highway.
			The concession title will be delivered June 3 and construction is expected to begin August 1, 2011, to be completed in 2 years. A total of approximately $5.0 billion pesos has been allocated for this project.
	•		Power Plant.- Grupo México and Siemens signed a US$242 million contract for the turnkey construction of a combined cycle power plant that will have a generating capacity of 250 megawatts. The plant will cover 100% of our power needs in the State of Sonora, reducing our energy costs which currently account for 30% of the total cost. To date US$35 million has been spent and the project reports 11% progress.
	•		Grijalva River Tunnels.- Regarding the construction of the tunnels on the Grijalva River that México Constructora Industrial has been working on since 2009, the work volumes have increased due to additional tasks resulting in negotiations with the CFE to increase the contract amount to $850 million pesos. This important project is expected to be completed June 15, 2011.
	•		Hydroelectric Plants.- GMéxico signed an agreement with the state of Puebla to develop micro-hydroelectrics and generate renewable energy.
	•		Sonora Platform.- On March 16, Perforadora México signed a contract with Pemex Exploration and Production to rent its Sonora Platform, which started operations March 23.

Metals Market

Copper prices continue to strengthen given the expectations for high consumption and the rebound of the construction sector. Prices have also been supported by a weak dollar. The earthquake in Japan has resulted in slightly lower consumption worldwide, which will be compensated by very high consumption once reinitiation of production in plants and reconstruction of housing in Japan starts. We therefore remain confident in the industry fundamentals and believe there will be a deficit in copper production and consumption during 2011. This is due to increased demand from China, despite the efforts of the Chinese government to moderate growth.

We have also seen a recovery in molybdenum prices, which could rise further in the future given the significant demand for steel expected from Japan.

Similarly silver prices have increased significantly as silver, like gold, is now being used for international reserves and there is an increased demand from the jewelry industry, principally in India and China with two digit growths.

The increase in sulfuric acid prices benefits us considerably (i) given the increased production on smelting concentrates from Buenavista, and (ii) on the technical stoppage for maintenance at the smelter in Peru having ended, increasing the capacity of the smelter by 10%.

First Quarter 2011 Results

Mining Production

Mined copper production in 1Q11 increased 5.2% to 167,091 tons, compared to 158,852 tons in 1Q10. This increase was mainly due to the restart of production at the Buenavista mine, which contributed with 27,598 tons. Greater production is expected in the coming quarters with Buenavista operating at full capacity and the completion of the optimization of the mine’s recovery process.

Asarco’s mined copper production in 1Q11 decreased 13.5% to 42,897 tons, compared to 49,608 tons in 1Q10. This decrease was mainly due to 6,711 tons less production because of lower ore grades at the Mission (4,737 tons) and Ray (2,319 tons) mines.

Copper production for 2011 is estimated at 830,000 tons, of which 630,000 tons will be produced by SCC mines and 200,000 tons by Asarco mines.

Molybdenum production decreased 10% to 4,274 tons in 1Q11, compared to 4,753 tons in 1Q10. This decrease was mainly due to lower ore grades at Cuajone. However production was above that estimated and mine planned.

Refined silver production decreased 9.8% in 1Q11 to 3.3 million ounces, down from 3.7 million ounces in 1Q10. This decrease was mainly due to 0.3 million ounces less material processed to third parties at our IMMSA plants in Charcas and Santa Bárbara, as a result of lower grades and no production at the Santa Eulalia mine. The Santa Eulalia mine, as announced previously, suspended production in May 2010 due to flooding in the mine caused by heavy rains. We expect to restore operations at Santa Eulalia mine in October 2011.

Sales and Cost

Sales for 1Q11 were US$2.091 billion, 27.7% higher than the US$1.637 billion reported for 1Q10. This increase is due to improved prices for the metals AMC produces, and the start of operations at Buenavista. Asarco sales for 1Q11 were US$514 million, compared to US$418 million in 1Q10, represents an increase of 23%.

The consolidated AMC operating cash cost per pound of copper (cash cost), net of byproducts, was US$64.2 cents per pound in 1Q11, compared to US$35.6 cents per pound in 1Q10. The increase is principally due to less copper production, increased stripping at the Asarco mines, and higher fuel and energy costs.

Sales Distribution

Projects and Exploration

The Molybdenum plant project at Buenavista continues to advance. The review of the basic engineering was completed in March 2011. The detailed engineering started in April 2011 and when completed in 3Q11, the main equipment will be purchased and construction will begin on the plant, which will have a capacity of 2,000 tons of molybdenum concentrate. The plant is expected to start operations in 4Q12.

Work continues on the expansion project at Cuajone and US$43.1 million of the US$301 million allotted had been invested as of close 1Q11. The purchase of mine and support equipment to optimize the plan for the mine is ongoing. The project considers an increase in the milled ore capacity and includes a variable cut-off grade methodology that will increase copper and molybdenum projection in the second half of 2011.

US$124.4 million has been invested in the expansion of the concentrator at the Toquepala mine in Peru. The use of high pressure grinding rolls (HPGR) and a wet process for the tertiary grinding stage will reduce capital and operating costs. The scope of the project is currently under review as we are evaluating an increase in milling capacity to 60,000 tons per day from the 40,000 tons per day originally planned.

Capital expenditures for Asarco in 1Q11 were US$16.2 million, mainly attributable to maintenance projects at the Smelter, and also payments made on four new 400-ton Liebbher trucks for the Ray mine to be delivered during the second half of 2011, which will complete the fleet of 21 new trucks.

Asarco began a pre-feasibility study in February 2011 for the project to restart a molybdenum circuit at the Mission mine. The study is expected to be completed in May 2011. Also, the exploration and drilling program continues and the proven reserves at the different mines are expected to increase by the end of 2011.

The volume transported by ITM during 1Q11 increased 3%, moving 12.548 billion net tons/km, compared to 10.426 billion moved during 1Q10. The volume transported by Ferromex during 1Q11 increased 3%, moving 10.746 billion net tons/km. The sectors that reported the greatest increase were: intermodal 33%, minerals 14%, and metals 9%. The volume transported by Ferrosur during 1Q11 increased 5%, moving 1.802 billion net tons/km.

Transportation Division revenue increased 18% to US$383 million in 1Q11, compared to US$326 million in 1Q10. This increase is explained by increased volume as a result of economic recovery and a more favorable mix of rates and traffic.

The operating cost for 1Q11 was US$262 million, 23% above that for 1Q10. This increase is explained by the additional freight volume, a 27% peso increase in the price of diesel, increases in locomotive leasing, labor, maintenance, and connection and terminal services.

EBITDA for 1Q11 was US$108 million (equivalent to 28% of sales), representing a decrease of 2% compared to 1Q10, due mainly to higher operating costs as a result of increased diesel prices.
