Partnerships
Nuton’s global presence
We aspire to create the best products in the world, and the best products for the world.
We know this hinges on the power of strong partnerships, so we actively seek partners with an open mind and open communication. Through collaboration, we continuously improve our performance to ensure Nuton copper is responsibly produced, and that the value we create is shared.
Each partner brings unique resources and perspectives, and we contribute our 30 years of research and development, uniquely tailoring our suite of technologies for their needs. Together, we aim to responsibly produce copper for a more sustainable future.

AntaKori, (Regulus Resources) Cajamarca-Peru
AntaKori is a brownfield project located in the active mining district of Yanacocha-Hualgayoc, in Cajamarca. It is immediately adjacent to the operating mine of Tantahuatay. At an altitude of 4,000m, AntaKori has indicated mineral resources of 250 million tonnes with a grade of 0.48 % Cu, 0.29 g/t Au and 7.5 g/t Ag, as well as inferred mineral resources of 267 million tonnes with a grade of 0.41% Cu, 0.26 g/t Au and 7.8 g/t Ag.
Nuton holds approximately 16% of Regulus Resources and sees great potential to use Nuton technologies at this and other sites.
Cactus Mine and Parks/Salyer (Arizona Sonoran Copper Company) Arizona-US
The Cactus Mine (formerly the Sacaton Mine) is a brownfield open-pit mines, located at the convergence of three major geologic zones in western Pinal County, Arizona. Parks/ Salyer is an exploration stage project contiguous to the Cactus Mine that Arizona Sonoran believes is a scalable underground opportunity for further expansion of leachable inventory.
In 2023, Arizona Sonoran granted Nuton an exclusive option to joint venture that provides Nuton the ability to acquire up to a 40% interest in ASCU´s Cactus Project for total funding of up to US$33 million in cash. Nuton is currently conducting column testing at this site, which will inform future applications of the technologies.
Escondida, (BHP) Antofagasta-Chile
Escondida is the largest producer of copper concentrates and cathodes in the world. Located in Antofagasta region, this mine is operated by BHP, which is the majority owner (57.5%) in a joint venture with Rio Tinto (30%) and a Japanese consortium, JECO Corp (12.5%). Escondida’s two pits feed three concentrator plants, as well as two leaching operations (oxide and sulphide). In Escondida´s growth pathway, Nuton is being studied as one of the competing technologies in leaching.
Los Azules, (McEwen Copper) San Juan-Argentina
Los Azules is a greenfield project located in San Juan Province, 6 km east of Argentina’s border with Chile, at an average of 3,600m elevation in the Andes Mountains. This advanced-stage porphyry copper exploration project is considered within the top 10 largest undeveloped copper resources in the world. The deposit includes 10.9 B pounds of copper in indicated resources and 26.7 B pounds in inferred resources.
Los Azules deposit has a 28-year mine life producing 175,000 tons of copper per year with supergene resources only. If the Nuton process is used to process primary resources, the mine life could potentially increase to 40 years.
The Project has a low carbon footprint, estimated in the lowest 15% of copper projects in the world at 826 kg of CO2 equivalent emissions per ton of copper produced. The ultimate goal of the project is to be net-zero carbon emissions by the year 2038.
Nuton holds approximately 14.5% of McEwen Copper and sees great potential in deploying the Nuton technologies at this and other greenfield sites, and to partner in McEwen Copper’s sustainability vision.
Johnson Camp Mine, (Excelsior Mining) Arizona-US
Johnson Camp Mine (JCM) is an inactive open pit mine, located in Southern Arizona’s Cochise County. Nuton is partnering with JCM to commercially demonstrate the Nuton technologies on a 2-million-ton heap and process the leach solution at the existing Solvent Extraction & Electrowinning plant.
Yerington, (Lion Copper & Gold) Nevada-US
The Yerington Mine is a past producing open-pit copper mine located in the Yerington district in Nevada – one of the largest copper districts in the United States, with +10mt of contained copper. Formerly operated by the Anaconda Copper Mining Company, this asset produced approximately 360 million tons of material from the pit between 1952 and 1978. At this legacy site, Nuton aims to deploy its technology to recover additional copper by targeting rock left unmined in the Yerington Mine as well as residual materials that were previously considered uneconomic.
Partner with us
Unlock more copper from your resources, using nature-based alchemy. We welcome the opportunity to partner with owners or custodians of copper sites, including early-stage copper mine projects, existing mines, and legacy mines. Together, we have the potential to create value and elevate environmental performance.
