San Martin Silver Mine



Overview



Tanks at San Martin
The San Martin Silver Mine is 100% owned by First Majestic Silver Corp. The mine holds 33 contiguous mining concessions in the San Martin de Bolaños mining district that cover mineral rights for 37,518 hectares. San Martin also has 1,295.8 hectares of surface land that cover the areas where the company has the mines access, mine installations, and part of the access roads as well as an additional 160 hectares of surface land where the processing plant, camp, office facilities, maintenance shops, and tailings dams are located. (Mineral rights and surface land rights are independent of each other.) The San Martin mill also underwent an expansion from 950 tpd to 1,300 tpd which was completed in October 2013. At full capacity of 1,300 tpd, San Martin's annual silver production is anticipated to increase by over 50% to approximately 1.4 - 1.6 million ounces of silver in the form of doré bars.




Location


Conveyor system from primary crusher

The San Martin Silver Mine is located 250 km north of Guadalajara city in Jalisco State, Mexico. Drive time from the city to the mine is approximately four to five hours, or about 45 minutes by charter plane. San Martin is also near the small town of San Martin de Bolanos, which is just 7.9 km to the east. San Martin de Bolanos has a population of about 3,500 and the mine is a major contributor to the economy of the community.

San Martín de Bolaños offers retail, medical (including General and Seguro Social hospitals), educational (including Jr. and High School), and communications facilities; however, major facilities, including an International Airport, are located in the cities of Guadalajara, Zacatecas and Aguascalientes.



Mining & Milling Operations

San Martin has undergone several improvements since the site was acquired by First Majestic in 2006. The most recent mill expansion (from 950 tpd to 1,300 tpd) was completed in October 2013. At full capacity of 1,300 tpd, San Martin's annual silver production is anticipated to increase by over 50% to approximately 1.4 - 1.6 million ounces of silver in the form of doré bars. Other elements of the modernization program included two new induction furnaces with two new filter presses, which were completed in 2011 and are now fully operational. These improvements are having a positive impact on overall production, quality of doré and total cash costs. Further improvements also included new leaching tanks and new thickeners.

Local Geology, Mineralization & Ore Types

San Martin is situated above the base of the western graben escarpment. The mine is centered on the Zuloaga Vein, which is by far the most extensively developed vein in the district, having accounted for approximately one-half of all silver production.

For more detailed geological information, readers are encouraged to review the Company's most recent NI 43-101 report on the San Martin Silver Mine. The Reserves/Resources inventories are reported in NI 43-101 Technical Reports published periodically by the Company. The complete report can be viewed in the Reserves/Resources section or on SEDAR.
