RecycLiCo Battery Materials Inc. and Alaska Energy Metals Corp. have started testing metal concentrate samples from the polymetallic Eureka deposit at the Nikolai Nickel Project in Alaska. The work is being conducted at RecycLiCo’s laboratory in Delta, BC, using a protocol prepared by RecycLiCo and approved by AEMC.

#Testing linked to earlier memorandum of understanding

The samples were produced from drill core collected during the 2023-2024 exploration campaigns at Eureka. The programme advances a previously announced memorandum of understanding between Alaska Energy Metals and RecycLiCo’s U.S. subsidiary.

Under the arrangement, the companies are assessing how RecycLiCo’s hydrometallurgical processing technology could be applied to material produced from the deposit. The current work is focused on evaluating possible approaches for refining the bulk concentrate.

#Metals contained in the Eureka deposit

According to the announcement, Eureka contains seven U.S. Government-designated Critical Minerals: nickel, cobalt, copper, chromium, platinum, palladium and gold. The deposit also contains iron, described by the company as a non-critical mainstay metal.

Alaska Energy Metals is focused on delineating and developing the Eureka deposit, which it describes as a large-scale, bulk-tonnage polymetallic project. The Nikolai Project is located in Interior Alaska near existing transportation and power infrastructure, according to the company.

#Multiple processing routes under review

The announcement said recently reported locked cycle flotation results showed strong recoveries of metals into a bulk nickel-copper concentrate. AEMC is examining multiple hydrometallurgical testing routes to identify the extraction technique it considers optimal for downstream processing of that concentrate.

Richard Sadowsky, RecycLiCo’s Interim CEO, said the company expects the work to assess its hydrometallurgical solutions for recovering high-value materials and described the testing as part of the companies’ continuing collaboration.

Alaska Energy Metals President and CEO Gregory Beischer said AEMC had been invited to join Minerals for National Automotive Competitiveness, a collaboration involving upstream raw material suppliers, mid-stream metal refiners and end users in the American automotive industry. The group includes RecycLiCo and Lucid, among others, according to the announcement.

#Company activities

RecycLiCo describes its business as focused on hydrometallurgical technologies for processing mined ore and upcycling lithium-ion battery materials. Its stated processes recover lithium, cobalt, nickel and manganese from end-of-life batteries and manufacturing scrap.

Alaska Energy Metals is an Alaska-based corporation with offices in Anchorage and Vancouver. In addition to the Nikolai Project, it holds the Angliers - Belleterre project in western Quebec.

#Key Takeaways

  • RecycLiCo and Alaska Energy Metals have begun testing concentrate samples from the Eureka deposit.
