Arca banks CICE funds for air-to-rock carbon mineralisation project at BHP Nickel West Mt Keith

Arca, the carbon mineralisation company, has announced that the B.C. Centre for Innovation and Clean Energy (CICE) has provided the company with a C$1.25 million ($910,966) grant that will be used to support a pilot project on air-to-rock carbon mineralisation using the mine tailings in BHP Nickel West’s Mt Keith mine in Australia.

CICE chose to provide the grant to Arca as it is one of the first companies commercialising mineralization for the capture and storage of atmospheric CO2 that is supported by leading-edge scientific research and technology development, it says. With this grant, Arca is now set to implement and scale its solution in a global setting.

The 18-month project will test and verify Arca’s methodology to capture and permanently store atmospheric carbon dioxide, and demonstrate to the mining industry that Arca’s technologies can integrate safely and successfully at an operating mine site, it said.

Low-grade disseminated sulphide ore is mined from Mt Keith, a large open-pit operation, at Nickel West, while high-grade nickel sulphide ore is mined at the Cliffs and Leinster underground mines. The ore is processed through two large concentrators and dryers at Mt Keith and Leinster, while Nickel West’s concentrator plant in Kambalda processes ore and concentrate purchased from third parties, BHP says.

As early as 2020, BHP said it was looking to add to the approximately 40,000 t/y of CO2 stored directly in the Mt Keith tailings dam.

Todd Sayers, Chief Operating Officer of CICE, said: “Arca is truly a pioneer in engineered mineralisation for carbon removal. The company’s powerful combination of world-leading science and innovation, team experience and global scaling strategy strongly aligns to the CICE mandate. With CICE’s support, Arca is in a great position to accelerate large-scale implementation.”

Arca enables mines to permanently remove CO2 while producing the metals needed to drive the clean energy transition. Using rovers, surface manipulation technology and machine-learning algorithms, Arca says it manipulates mine tailings to significantly speed up the rate of carbon mineralisation; measure critical carbon capture; and sell carbon dioxide removal credits that are verifiable and permanent. This process is unique, it says, because atmospheric CO2 is captured and stored in a single step.

Dr Greg Dipple, co-Founder of Arca, said: “CICE’s grant represents a significant milestone for Arca as it allows us to fast-track our ability to bring our technology and innovation to mining companies around the world, and accelerate our collective mission to support a net-zero carbon future.”

Arca says it works with producers of critical metals around the world, helping them assess and quantify the carbon mineralisation potential of their mine tailings. Its technology has been recognised with a $1 million XPRIZE Milestone Award for Carbon Removal, two Foresight50 awards, and is supported by Sustainable Development Technology Canada, National Research Council of Canada Industrial Research Assistance Programme, Lower Carbon Capital and the Grantham Foundation.

Arca’s carbon sequestration tech gaining traction with mining company engagements

Arca has announced that it is working with producers of nickel to advance carbon dioxide removal at mine sites on three continents, having engaged with Vale, Talon Metals, Poseidon Nickel, NickelSearch and Blackstone Minerals.

The company, which calls itself a leader in carbon mineralisation, works globally with nickel mine developers and operators to capture and permanently store CO2 in mine tailings using its technology.

Arca is developing and commercialising a portfolio of technologies that help mining companies measure, maximise and monetise the carbon sequestration potential of their mining by-products. Arca’s patent-pending mineral activation technology uses high-intensity bursts of energy to transform and disrupt the mineral lattice structure of magnesium-rich minerals, increasing both the rate and capacity for CO2 capture and permanent storage.

With material from its mining company partners, Arca says it has achieved never-before-seen rates of air capture and capacity for CO2 storage, operating at atmospheric air temperature and pressure.

Arca can work with legacy (closed) mines, junior (under-development) mining companies, as well as existing mine operations of any size, and says it is currently working with mining companies in key mining jurisdictions such as Canada, Australia, the US and Southeast Asia.

Today, Arca announced it is working with the global mining major Vale, the Australia-based juniors Poseidon Nickel and NickelSearch, and Blackstone Minerals.

Arca is also working with Talon Metals which, in a joint venture with Rio Tinto, is developing the US’ only high-grade nickel resource for the domestic battery supply chain.

“Talon and Arca are working on transformational change in mining and mineral processing,” Todd M Malan, Head of Climate Strategy, Talon Metals, said. “Our partnership is focused on showing how ‘waste’ from conventional nickel processing can be harnessed to store carbon that has been removed from the atmosphere or captured in industrial processes. This ‘waste-as-carbon-sink’ approach has further potential for reuse in building materials, thus significantly reducing the amount of waste that needs to be stored as compared to present day legacy nickel processing.”

Professor Greg Dipple, co-Founder and Head of Science at Arca, said: “Arca is helping mining companies understand the potential for mineralisation of their resources, design how that potential should be realised, and then advance to actual project development. Our mineral activation technology significantly accelerates the natural process of carbon mineralisation using mine tailings from ultramafic rocks. This helps these companies transform their tailings into industrial-scale direct air capture and storage facilities, transforming mine waste into a valuable new resource and climate solution.”

Arca has been recognized with a $1 million XPRIZE Milestone Award for Carbon Removal, a Foresight50 Award as one of Canada’s most investable cleantech ventures, and an SDTC Seed Fund grant.

Dr Dipple will be speaking in Perth, Australia, about Arca’s technology at the CSIRO symposium on locking carbon in minerals on June 20.
