| McEWEN MINING MUX McEWEN MINING COMPLETES LOCAL ROAD CONSTRUCTION In late March, McEwen Mining completed the paving of a 2 kilometer (1.24 miles) section of a road through the main part of the town called El Valle. El Valle, which is the largest population center near McEwen Mining’s operations in Sinaloa, Mexico, is located 8 kilometers (4.97 miles) from the company’s Phase 1 production area and home to more than 950 people. The paving of the El Valle road benefits more than two thousand people daily, who commute either to work or school. In addition, the paving has helped to reduce the amount of dust caused by traffic and also improve the air quality. With the improved infrastructure, McEwen Mining believes there is an excellent opportunity for additional businesses to enter the town and for property values to appreciate for local residents. Approximately 200 McEwen Mining employees are now using the road to arrive at the mine daily. A total of US$650,000 was invested in the project by McEwen Mining, making it the community’s first paved road. The road has two 7-meter (23 feet) wide lanes, three bridges, and all the required traffic signage. Rob McEwen, Chief Owner of McEwen Mining, together with the State Governor, Mario Lopez, Mocorito Municipal Mayor, Gloria Himelda and other local dignitaries carried out a ribbon cutting ceremony on April 2, 2012. The Governor was accompanied by the Economic Development Secretary, Eduardo Ortiz and the head of Public Security Secretary, Franco Cordova. The event gathered over 200 local attendees, in addition to McEwen Mining staff from Mexico and Canada. Rob McEwen and the Governor shared their excitement about the completion of the road project with the audience. In addition, they also discussed the future economic developments that could help transform the region through mining and exploration being conducted by McEwen Mining. The first phase of production at the El Gallo Complex will commence during the Third Quarter and will create approximately 250 full-time jobs. The second phase, scheduled to begin in 2014, could see this number double to more than 500 people. “Today I realized how pretty El Valle is. This town produces good peanuts and sugar mills, hard working men and beautiful women. I also now have a new friend Rob McEwen, who with his mining company has created jobs and benefits for many families in this community,” said the Governor, Mario Lopez during the ribbon cutting ceremony. The McEwen Mining team is thrilled to have built the El Valle road and witnessed the community’s overwhelming reception to the project. *Before and after photos located on page 2 Pg. 1
