Cobalt Blue–Glomar Minerals JV: process design and capex lens for US cobalt
Reviewed by Joe Ashwell
First reported on Australian Mining
30 Second Briefing
Cobalt Blue has signed a consortium agreement with US-based Glomar Minerals to deploy its Australian-developed cobalt processing technology in the United States, targeting domestic production of battery-grade cobalt sulphate. The partnership centres on applying Cobalt Blue’s proprietary sulphide-to-sulphate flowsheet, originally engineered for Broken Hill-style deposits, to US feedstocks to reduce reliance on imported intermediates. For process and project engineers, the move signals potential demand for new hydrometallurgical plants, tailings handling systems and permitting work around cobalt-bearing ore bodies in the US.
Technical Brief
- Similar cross-border technology consortia could de-risk metallurgical scale-up for other critical minerals (e.g. nickel, manganese).
Our Take
Cobalt-related items are relatively sparse in our mining database compared with lithium and copper, so a JV-led US push involving Cobalt Blue signals that downstream users are still looking to diversify cobalt supply chains beyond the DRC and Indonesia.
Australian–US combinations in project and contract-award stories have tended to focus on technology transfer rather than pure equity investment, suggesting this JV may be more about deploying Australian processing know‑how in the US than shifting large volumes of ore from Australia.
For a mid-tier player like Cobalt Blue, JV structures into the United States typically provide leverage into US federal incentives for critical minerals, which can materially de-risk project financing compared with staying solely in Australian jurisdictions.
