Canadian-based Primero Mining has positioned itself as a reference in technological innovation, safety standards, social responsibility, and clean energy use in Mexico, particularly in the state of Durango. The company only has operations in Canada and Mexico, where it seeks to become a leading intermediate gold producer. It is well on the way to achieving this goal as it produced a total of 185,000-205,000oz of gold in 2014, of which 120,000- 130,000oz were produced in Mexico. Similarly, Primero Mining's Mexican operations produced 6.1-6.3 million ounces of silver for the same period. This success stems from Primero Mining's San Dimas gold and silver deposit, which is one of Mexico's most important precious metal deposits. Historical production from the San Dimas district, which measures 15km2, has reached an estimate of 11 million ounces of gold and 582 million ounces of silver since the first mining efforts in 1757. The district has passed through a number of hands before Primero took it over.
