Pumpkin Hollow restart project.

Location
Near Yerington, Nevada, in the US.

Project Owner/s
Kinterra Capital announced the completion of the acquisition of Australia’s New World Resources in November 2025. 

The company now controls an estimated 175 000 t/y of copper production capacity across its US portfolio – from Pumpkin Hollow and the adjacent Southwest openpit, in Nevada; Antler, in Arizona; and White Pine, in Michigan.

Project Description
The Pumpkin Hollow restart will bring about 60-million pounds of copper back into domestic production. 

The project is fully permitted, carries no debt or stream obligations and benefits from more than $1-billion of installed infrastructure.

Potential Job Creation

Net Present Value/Internal Rate of Return
The openpit operation has an estimated pretax net present value (NPV), at a 7.5% discount rate, of $1.04-billion and an internal rate of return (IRR) of 23%, with a payback of 4.5 years. Together, the underground and openpit operations have a pretax NPV, at a 7.5% discount rate, of $1.32-million and an IRR of 24%.

Capital Expenditure
Initial capital expenditure for the openpit is estimated at $627-million.

Planned Start/End Date
The restart is expected in the second quarter of 2026.

Latest Developments
Kinterra Capital has secured an indicative $200-million financing commitment from the Export-Import Bank of the United States (Exim) under the agency’s Make More in America initiative. This enables the company to fully fund the restart of the Pumpkin Hollow underground copper mine and advance the Southwest openpit project.

The nonbinding letter of interest outlines $180-million in potential debt funding for Pumpkin Hollow’s restart and $20-million to advance technical work at the Southwest openpit.
Exim’s letter notes that the transaction may qualify under Section 402 of its 2019 Reauthorisation, which prioritises projects that enhance US industrial leadership and reduce reliance on foreign supply chains. If approved, it could benefit from accelerated review, enhanced support and flexible financing terms.
