In 2023, Kinterra’s Fund I secured a majority stake in White Pine Copper LLC, positioning the firm at the forefront of one of the largest undeveloped copper projects in the United States. Building on a legacy of historic production, the White Pine North Project combines scale, existing infrastructure, and strong community roots to advance a new chapter in Michigan’s Upper Peninsula mining history.

Project Overview
In 2023, Kinterra’s Fund I acquired a 66% interest in White Pine Copper LLC, which is advancing the White Pine North Project near the town of White Pine in Michigan’s Upper Peninsula. The original White Pine mine operated from 1953 to 1995, producing roughly 4.5 billion pounds of copper over its life. White Pine North represents a brownfield extension of this historic operation, leveraging existing infrastructure, extensive historical data, and strong ties to a community with a deep mining tradition. With a resource exceeding 5.7 billion pounds of copper, White Pine North ranks among the largest copper developments in the United States not controlled by a major mining company.
A 2023 Preliminary Economic Assessment outlined an underground copper mine with a 22-year mine life and an average annual production of approximately 100 million pounds of copper equivalent at a 15,000 tonne-per-day processing rate. White Pine North is advancing baseline studies, trade-off analyses, and active stakeholder engagement to support future permitting.
Strategic Holdings
Our strategic holdings represent critical material projects and associated infrastructure that are essential to the modern economy. We invest in assets with scale, resilience, and clear development pathways, working alongside strong local partners to unlock long-term value.
Nion Nickel's Dumont Nickel Project is one of the world’s largest undeveloped nickel sulphide deposits, fully permitted and feasibility-stage, with the potential to integrate into a sustainable critical mineral supply chain in North America.
Kinterra’s acquisition of Cannon Resources Pty Ltd. added the Fisher East Project to Kinterra’s portfolio. Fisher East is one of Australia’s highest-grade undeveloped nickel sulphide assets.
New World Resources' Antler Project is a high-grade, development-stage underground copper project with strong economics, a clear permitting pathway, and significant potential to become a leading U.S. copper supplier.
NiVolt Technologies Inc. is a proprietary company of Kinterra, focused on advancing next-generation critical minerals processing solutions for the clean energy economy. By developing a scalable platform for producing high-purity nickel and cobalt products, NiVolt is positioned to play a critical role in strengthening the battery materials supply chain for electric vehicles and energy storage.
Kinterra’s Fund I strengthened its U.S. copper portfolio in late 2024 with the acquisition of the Southwest Open Pit Project, one of the nation’s most advanced, fully permitted undeveloped copper assets. Positioned for long-term growth and strategic importance, the project combines scale, strong economics, and a clear path toward construction.
The Pumpkin Hollow underground copper mine in Nevada is a permitted, restart-stage asset with 2 billion pounds of copper resources, established infrastructure, and strong community support, and is positioned to deliver long-life, reliable North American production.
