Del Toro Silver Mine


The Del Toro Silver Mine is 100% owned by First Majestic Silver Corp. Initial production at Del Toro's flotation circuit commenced in the first quarter of 2013, making it First Majestic's fifth producing silver mine. By the fourth quarter of 2013, the cyanidation circuit was successfully commissioned allowing for the production of silver doré bars. Current mining operations consist of production from four different underground areas (San Juan, Perseverancia, San Nicolas and Dolores).


The Del Toro Silver Mine holds 31 mining concessions covering 606 hectares of land. In addition, Del Toro also has 441 hectares of surface rights that cover the areas where the company has mine access, mine installations and access roads. This mine has a total land package of 1047 hectares in size.


The Del Toro Silver Mine is located in the Municipality of Chalchihuites, Zacatecas, Mexico. The site is just 60 km southeast of the Company's La Parrilla Silver Mine and will benefit from the local infrastructures (electricity, water and telephones) that are presently available in the area. Basic facilities including restaurants, hotels and gas stations can also be found in Chalchihuites, while major services including banks, repair shops, etc. can be found in Vicente Guerrero town and in Sombrerete town, both located just 50 km away. Access to the property is easily achieved due to the close proximity of Interstate 45 and the state roads which connect the Chalchihuites town to most of the mining claims.

Del Toro is located in the Chalchihuites silver mining district in the north-western part of Mexico, at the border zone between the physiographic provinces of Sierra Madre Occidental and Mesa Central. The mineralization at Del Toro occurs as an assemblage of metasomatic and hydrothermal mineral deposits with high-grade silver content including veins, replacement concentrations, stockworks and breccia zones.


Exploration at Del Toro has been primarily focused on the investigation of two areas: the San Juan and Perseverancia areas within the projects holdings. Both the San Juan and Perseverancia were historic mines; the Perseverancia was mined for high grade silver rich sulphide ore and the San Juan is believed to be the oldest mine in the district, possibly dating back 500 years.

More recently, the San Nicolas and Dolores areas have also been receiving attention. The San Nicolas and Dolores are two new areas of interest that are currently being defined by drilling. They consist of breccia chimney and vein deposits. Preliminary investigations for these two areas include underground development for both mapping and channel sampling to determine the size and quality of mineral deposits.
