Frontera is a copper mining company that operates the Piedras Verdes mine. The mine is located in southern Sonora, 25 minutes from Alamos and 35 minutes from Navojoa, where most employees live.
Piedras Verdes is an open-pit copper mine that operates on a conventional basis with a mining rate of ~135ktpd and processes it ore by heap leaching and Solvent Extraction & Electrowinning.
PV mines and processes sulfide and oxide ores, produces London Metals Exchange Grade “A” copper cathodes, and sells primarily hypogene ore that cannot be economically processed by heap leachng to Kupari Metals, an independently-owned tolling company that produces and sells copper concentrates.
Fully integrated with the CFE power grid and other infrastructure. All water is sourced from within the mine footprint. Within 1 hour and 15 minutes from two airports. The Ciudad Obregón International Airport operates ~20 commercial flights daily.
PV prioritizes safety, care for the community, and sustainability. It will continue to optimize capacity and recovery rates by maximizing the productivity of the mining fleet, minimizing mining dilution as the deposit becomes more highly disseminated, and selectively investing in enhanced processes focused on increasing crushing capacity, the proportion of crushed leach ore that is agglomerated and ore sorting. Investment decisions are driven by payback, internal rates of return, and their carbon footprint. As and when copper prices continue to increase, such investments will become increasingly compelling.
Our core values are focussed on the health, safety and wellbeing of our employees, contractors and other stakeholders, we operate to world-class environmental, social, and governance standards.
