The San Julián silver-gold project is a cornerstone of our current and future production goals. The geological potential identified in the region thus far may be sufficient to establish a new mining district in the future. The San Julián project includes construction of two plants: i) a dynamic leaching plant to treat ore from the veins and ii) a flotation plant with 6,000 tpd capacity to process ore from the disseminated body.
