Cerro San Pedro mine is a gold and silver mine located in central Mexico, around 20 km northeast of the capital San Luis Potosi, a city of which has approximately one million inhabitants with a strong industrial base. The mine is is easily accessed from the city center, and an international airport is not far away.
The Cerro San Pedro Mine is owned by New Gold through the Mexican Company, Minera San Xavier (“MSX”) with a stake of 100% and the first gold was poured in May 2007. This mine has a history about of ongoing legal challenges mainly due to a land use legality in area, and then the challenges were successfully overcome.
The Cerro San Pedro Mine has an enviable record of compliance with Mexican, about international environmental, safety standards, health and enjoys overwhelming local support as a trusted corporate citizen.
Mining History
Cerro San Pedro has been mined since the mid-1600s, production that have been generated on until the year 1940 around 2.5 million ounces of gold and 40 million ounces of silver. In 1592 padre Diego de la Magdalena with some of the peoples in Guachichil pueblo from Mesquitique.
Among them, a man named Cualiname or Gualiname, where they bring attention about the golden outlines in their face paintings. The missionary asked him where he had obtained this pigment, and was told that in the east of Mesquitique much of the powder.

Magdalena say to Francisco Franco approximately this discovery, and then notified to Captain Miguel Caldera , which is a of indigenous peoples for the Viceroyalty of New Spain and and that control of this region.
The latter named the locale San Pedro del Potosí, to honor his namesake saint and in memory of the famous mines of the Potosí in Alto Perú of the Viceroyalty of Peru, in present day Bolivia.
Several mining companies during the 1990s and the 2000s, has conducted mining operations in Cerro San Pedro before mining operations Metallica Resources and Peak Gold company merged to form New Gold in June 2008.
But now New Gold has already owns 100% of shares and operates it through its wholly owned subsidiary in Mexico Minera San Xavier.
But in December 2009 Operations were suspended after a court order prohibited the use of explosives at the mine site. In 17 March 2010 the decision of the federal court about the restrictions imposed by the previous court order and doing a wisdom by giving back operations at the mine.

Geology & Mineralization In Cerro San Pedro mine
The mining district is located in the Eastern Sierra Madre fold-and-thrust belt of east-central Mexico. The district was originally discovered by Spanish explorers during the late 16th century.
The local stratigraphic section is dominated by Cretaceous limestones which have been intruded from the San Pedro porphyry, a late Cretaceous to early Tertiary age monzodiorite intrusive body emplaced along a regional scale thrust fault.

The local stratigraphic section is dominated by Cretaceous limestones which have been intruded from the San Pedro porphyry, a late Cretaceous to early Tertiary age monzodiorite intrusive body emplaced along a regional scale thrust fault.
The mineralization occurs within an upper oxidized zone, disseminated gold and silver houses associated with iron oxides and a lower zone of gold-silver-zinc-lead sulphide mineralization.
Estimated the available historical records, among year 1575 and 1950 the Cerro San Pedro district produced approximately 2.5 million ounces of gold, for the production of silver by generating 40 million ounces of silver, while copper production generates around 93 million pounds and other products 405 million pounds of zinc, 224 million pounds of lead

Nearly all of this production carbonate replacement mantos, veins, and fireplaces in the limestones next to Pedro porphyry San, which is host to disseminated and stockwork style mineralization.
recently has opencast the oxide zone in the production of approximately 1.6 million ounces of gold and 78 million ounces of silver from both limestone and porphyry ore types.
When combined with historical estimates of Cerro San Pedro is quarter estimated more than 4 million ounces of gold and have 100 million ounces of silver and associated zinc, lead and copper.

Processing Ore In Cerro San Pedro Mine
Mine operates as an open pit. Run-of-mine ore is processed by heap leaching and the Merrill-Crowe recovery process to recovery process gold and silver doré. Process plants consist of a heap leach pad lined which leading to a conventional Merrill Crowe recovery circuit for gold and silver .
Run-of-mine ore is stacked on the leach pad and then a pregnant solution flows toward the bottom through the heap leaching of gold ore, which is then solution from result this mineral ore pumped to the Merrill Crowe plant for stages of the process produce gold-silver doré.
Then the results of doré is transported from location to a refinery, where the silver and gold to be refined to make gold bullion. Gold is then sold to bullion banks on the spot market
