Nevada Copper ships first Pumpkin Hollow concentrate

Following the start of production on December 16, Nevada Copper has shipped the first copper concentrate from its Pumpkin Hollow copper mine, in Nevada, USA.

Having reached these milestones, the company is now focused on ramping up the mine, in Yerington, to reach nameplate capacity in the first half of 2020.

The 2017 prefeasibility study plan for the underground mine outlined a 5,000 t/d project able to produce some 50 MIb/y (22,680 t/y) of copper, 8,000 oz of gold and 150,000 oz of silver over a 13.5-year life at all-in sustaining costs of $1.96/Ib of copper. It also laid the foundations for a larger integrated project that includes open-pit development and could increase throughput to 70,000 t/d.

Matt Gili, Chief Executive Officer of Nevada Copper, said: “Our first shipment of copper concentrate has left Pumpkin Hollow, representing another important milestone as we look forward to continuing our ramp-up to full commercial production in 2020.”

Both Cementation USA and Sedgman USA were involved in the Pumpkin Hollow build, with the former carrying out shaft sinking and underground mine development work and the latter completing the engineering, procurement and construction contract for the surface plant and infrastructure.
