Arca carbon tech funding: field‑scale mine waste mineralisation lens for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Arca Technologies has secured up to C$2 million from NRC IRAP’s Clean Tech initiative towards a C$7.4 million project to move its mineral activation and engineered carbonation processes from lab to field scale, targeting alkaline wastes such as mine tailings and steel slag. The company will design containerised, field‑deployable mineralisation units and prepare a first‑of‑kind industrial pilot, billed as the first field‑scale system to accelerate carbon mineralisation in mine waste. Commercial traction includes a 10‑year offtake with Microsoft for nearly 300,000 tonnes of CO₂ removal and an early pre‑purchase from Frontier.
Technical Brief
- NRC IRAP Clean Tech support combines advisory services with up to C$2 million in non-dilutive funding.
- Total project budget is C$7.4 million, structured as a research, development and demonstration (RD&D) programme.
- Funding is explicitly targeted at moving Canada-developed “Industrial Mineralization” technology into operating industrial environments.
- Arca’s process is framed around using alkaline wastes from mining, metals and steel manufacturing as feedstock.
- Containerised units are intended to be engineered, manufactured and deployed domestically within Canada’s cleantech ecosystem.
- Project scope includes field validation and partnership-building with industrial operators handling mine tailings and steel slag.
- The initiative is positioned to create skilled engineering and manufacturing jobs tied to mineralisation plant deployment.
- Canadian federal backing aims to reinforce mining and metals sectors by adding value pathways for by-products.
Our Take
With Uzbekistan’s gold exports valued at about US$1.5 billion through April and annual output around 130 tonnes, carbon-removal technologies like Arca’s could become a differentiator for gold producers seeking lower embedded emissions in a tightly scrutinised supply chain.
Merdeka Gold Resources’ planned US$500 million Hong Kong float, noted in our database alongside this Environmental piece, signals that gold companies looking to tap public markets may face growing investor questions on decarbonisation tools such as Arca’s field-deployable carbon tech.
