Arca and Giga Metals sign exclusive agreement to explore carbon removal at B.C. nickel project with potential to remove 220 million tonnes of atmospheric carbon dioxide
MWN-AI** Summary
Arca Climate Technologies Inc. and Giga Metals Corporation have entered into a significant 10-year agreement to explore carbon removal possibilities at Giga’s Turnagain Nickel Project in British Columbia. Signed on January 9, 2026, this exclusive agreement allows Arca to assess the potential of ultramafic mine tailings and waste rock to permanently capture atmospheric carbon dioxide. Both companies are optimistic about the environmental impact of this collaboration, as Giga Metals estimates that mining will generate around 1.3 billion tonnes of ultramafic material.
Arca’s approach utilizes proprietary Industrial Mineralization technology, which accelerates a natural geochemical process known as carbon mineralization. This process transforms CO2 into stable solid minerals, potentially enabling the removal of up to 220 million tonnes of carbon dioxide from the atmosphere over the project's lifetime. This partnership aligns with Canada’s 2022 Critical Minerals Strategy, which emphasizes the importance of nickel production to fulfill energy transition demands and highlights Canada’s ambition to be a leading global supplier of critical minerals.
Paul Needham, CEO of Arca, emphasized the significance of this project as a model that pairs critical mineral development with effective carbon capture, enhancing both project economics and societal benefits. Meanwhile, Scott Lendrum, CEO of Giga Metals, noted their long-standing collaboration with Arca focuses on maximizing carbon sequestration while maintaining high environmental, social, and governance (ESG) standards in nickel production.
This agreement symbolizes a forward-thinking approach to mining, merging resource extraction with innovative climate solutions, and reflects the increasing urgency for industries to adopt practices that reduce carbon emissions.
MWN-AI** Analysis
The recent exclusive agreement between Arca Climate Technologies Inc. and Giga Metals Corporation signals a pivotal opportunity for investors within the mining and climate technology sectors. By evaluating the potential of ultramafic tailings at the Turnagain Nickel Project for carbon mineralization, these companies are positioning themselves at the intersection of critical mineral production and carbon removal—a growing focus of both public policy and investor interest.
The Turnagain Project is notable as one of Canada’s largest undeveloped nickel resources, aligning with the Canadian government's 2022 Critical Minerals Strategy to secure a leadership role in the energy transition. This initiative underscores the rising demand for nickel, particularly in electric vehicle batteries and renewable energy technologies. With Giga Metals' partnership with Mitsubishi Corporation, there is also a level of operational and financial robustness that enhances investor confidence.
Arca's proprietary technology for carbon mineralization represents a significant innovation. By transforming mine waste into stable, solid mineral forms of CO2, they can offer miners not just a means to meet regulatory pressures but also a potential revenue stream through carbon credits. The estimated ability of this project to remove 220 million tonnes of atmospheric CO2 adds a compelling sustainability component to Giga's portfolio, enhancing its ESG credentials.
Investors should closely watch the developments from this partnership. The potential integration of advanced carbon removal technologies in mineral extraction processes may set new industry standards, leading to improved project economics and societal benefits. Companies demonstrating a commitment to sustainability can differentiate themselves, potentially attracting both institutional investor interest and favorable policy support. Therefore, maintaining a position in Giga Metals could yield valuable dividends in the future as global demand for both nickel and innovative climate solutions surges.

Arca Scientist Eric Wynands working with rover on ultramafic mine tailings at a mine site in Western Australia in 2025
VANCOUVER, British Columbia, Jan. 14, 2026 (GLOBE NEWSWIRE) -- Arca Climate Technologies Inc. (“Arca”), an Industrial Mineralization company, and Giga Metals Corporation (“Giga Metals”) (TSX-V: GIGA; OTCQB: GIGGF; FSE: BRR2), a Canadian mining company advancing the Turnagain Nickel Project in British Columbia in partnership with the Mitsubishi Corporation, today announced a 10-year tailings and waste rock access agreement that was signed January 9, 2026.
The agreement grants Arca an exclusive right to evaluate the potential of the ultramafic waste rock and mine tailings at the Turnagain Project to permanently remove carbon dioxide from the atmosphere. Arca will conduct sampling, analysis, pilot-scale testing, and techno-economic studies using its proprietary Industrial Mineralization technology.
Giga Metals estimates that approximately 1.3 billion tonnes of ultramafic material will be generated at the site once mining commences. Arca’s technologies activate minerals found in ultramafic rock, accelerating a natural geochemical process called carbon mineralization – the transformation of atmospheric CO2 into stable solid mineral form. Co-benefits related to waste valorization and mine site sustainability are also generated. Arca estimates that the deployment of its technologies on site will create the lifetime potential to remove up to 220 million tonnes of carbon dioxide from the atmosphere.
The Canadian government 2022 Critical Minerals Strategy identified nickel production as a national priority to meet the demands of the energy transition, with the goal of making Canada a global supplier of choice for critical minerals. The pursuit of this goal has been enhanced recently by new Canadian Federal Government investments and policies such as the Critical Minerals Sovereign Fund, the Defence Industrial Strategy and the Major Projects Office.
“As Canada seeks to strengthen our economy and our position as a leading producer of critical minerals, Turnagain stands out as one of the largest undeveloped nickel resources in the country,” said Paul Needham, CEO of Arca. “By pairing critical minerals development with permanent carbon dioxide removal, Giga Metals and Arca will demonstrate a new mining paradigm with enhanced project economics and broader societal benefit.”
“At Giga Metals we have been working with Arca Principals on carbon sequestration for more than a decade,” said Scott Lendrum, CEO of Giga Metals. “We are pleased to formalize our arrangement to allow both companies to focus on what they do best: produce nickel concentrate with high ESG credentials, and maximize the permanent sequestration of carbon dioxide by converting mine waste into reactive sequestration minerals. Working with Arca allows us to evaluate emerging technologies that could enhance the environmental and economic performance of the Turnagain Project while supporting innovation in the mining sector.”
About Giga Metals
Giga Metals Corporation’s core asset is the Turnagain Project, located in northern British Columbia, which contains one of the few significant undeveloped sulphide nickel and cobalt resources in the world. Turnagain is held in Hard Creek Nickel, a subsidiary owned jointly by Giga Metals Corporation and Mitsubishi Corporation.
The Turnagain ultramafic complex is also prospective for copper, platinum and palladium mineralization in the Attic Zone, an area adjacent to the known nickel resource.
