About Us

Frontera Copper Corporation

Frontera is a copper mining company that operates the Piedras Verdes mine 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 ~200ktpd and heap leach and SX/EW processes

It mines and processes sulfide and oxide ores, produces London Metals Exchange Grade “A” copper cathodes and sells primarily hypogene ore 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 mine footprint. Within 1 hour 15 minutes from two airports, the Ciudad Obregón international airport operates ~20 commercial flights per day.


PV will continue to optimise 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 and the proportion of crushed leach ore that is agglomerated. Investment decisions will be driven by payback, internal rates of return and their and carbon footprint. As and when copper prices continue to increase, such investments will become increasingly compelling.

This will occur while prioritizing safety, care for the community and sustainability.


Our core values include the health and safety of our employees and contractors, and a commitment to operate in accordance with world-class environmental, social and governance standards.
