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

About this update from Giga Metals Corporation

  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 economi...
