Turnagain nickel project partners with Arca and Giga Metals on carbon removal strategy

Giga Metals and Arca signed a 10-year tailings and waste rock access agreement at the Turnagain nickel project so Arca can evaluate mineralization-based permanent carbon removal; Arca estimates a lifetime potential to remove up to 220 million tonnes of CO2.

Arca Climate Technologies and Giga Metals announced a 10-year tailings and waste rock access agreement for the Turnagain nickel project in British Columbia. The agreement grants Arca exclusive rights to evaluate whether ultramafic waste rock and mine tailings can be used to permanently remove atmospheric carbon dioxide. Arca will carry out sampling, analysis, pilot-scale testing and techno-economic studies using its Industrial Mineralization technology. The Turnagain deposit is being advanced by Giga Metals in partnership with Mitsubishi and hosts minerals that naturally carbonate, such as olivine, serpentine and brucite. Key facts: - The agreement gives Arca exclusive access to evaluate tailings and waste rock at Turnagain for up to 10 years. - Arca will perform sampling, pilot-scale testing, analysis and techno-economic studies with its Industrial Mineralization process. - Tests conducted by Giga and Arca at the University of British Columbia in 2021 indicated the site has potential for significant mineral CO2 sequestration. - Giga Metals estimates the site will generate about 1.3 billion tonnes of ultramafic material once mining begins. - Arca estimates deployment of its technologies at Turnagain could have a lifetime potential to remove up to 220 million tonnes of CO2. - The article mentions the Canadian government’s 2022 Critical Minerals Strategy and that Giga Metals stock was up 3.7% by market close in Toronto, with a reported market capitalization of C$17.7 million. Summary: The agreement formally allows Arca to test and evaluate carbon mineralization at the Turnagain site and to study the technical and economic aspects of deploying its technology there. The next scheduled work described in the article is sampling and pilot-scale testing; broader project outcomes and timelines are undetermined at this time.
