El Placer II

The area has a long mining history with numerous informal miners and well-established local mining companies reportedly operating in the region since the 1700’s until the early 1900’s. Together with the Rosario Mining District, the Concordia Mining District was historically a buoyant mining district from the 1700’s to early 1900’s. There were four large processing plants: San Nicolas- Hernandez (Compania Minera Panuco), Santa Rossa and Rio Florido. The historical records indicated processing of gold silver rich ores and base metals lead-zinc ores with gold and silver as by-products. Modernization occurred in the early 1900’s with introduction of cyanide leaching in the district.

The El Placer II concession covers 111,000 hectares. The area hosts many sites with evidence of historical artisanal mining. The following royalty interest is related to the Villa Union: 1.0% NSR to Sandstorm.
