Capstone Copper - Operations

With a portfolio of long-life copper mines and a pipeline of fully-permitted new developments, Capstone Copper is well positioned to create growth in the short term as we make our existing mines more profitable, and in the long term as we build the next generation of responsible copper mines.

Through a commitment to innovation, excellence and operating at the highest standards, we are committed to generating strong cash flows in all price environments with our multi-asset portfolio of mines and projects. We are on target towards sustainable 200 million pounds copper production by 2022.

Exploration Excellence

Our exploration team has delivered net asset value creation through the drill bit. Major league results at multiple Capstone assets, both previously and currently owned, has proven the team’s exploration excellence. The Exploration page outlines our current brownfield and greenfield focus areas.

Innovation

Pinto Valley has successfully demonstrated positive economics by applying the novel patented Jetti Catalytic Leach Technology to existing dump leach operations. The plan is to increase copper cathode production to 300-350 million pounds from residual and high-grade waste over the next two decades, thereby generating strong cash flow from the mine’s underutilized SX-EW plant, which is currently operating at only 20% capacity.

In addition, the PV4 prefeasibility study currently underway aims to maximize the conversion of approximately one billion tonnes of mineral resources to mineral reserves, significantly extending Pinto Valley’s mine life and increasing its copper production profile through the expansion of the use of Jetti’s technology and other projects such as Pyrite Agglomeration and Coarse Particle Flotation.

At Cozamin, an ore sorting technology study is evaluating the option to convert significant copper and silver from a large mineral resource into a new mine plan.
