Cobalt Blue Holdings Ltd (ASX:COB) enters cobalt feedstock agreement with Glencore International AG
Agreement supports early throughput for Australia’s first cobalt sulphate refinery
Refinery project aligns with national critical minerals strategy and ESG standards
Cobalt Blue Holdings Ltd (ASX:COB), a company active in the battery metals and critical minerals sector, has announced a feedstock supply agreement with Glencore International AG for its Kwinana Cobalt Refinery. The news places the company in focus within the ASX 200, highlighting increased activity in projects tied to Australia's critical minerals development and battery supply chain initiatives.
The cobalt feedstock will be supplied by Glencore’s operations located in the Democratic Republic of Congo, with material expected to meet responsible mining standards. The agreement is designed to meet a substantial portion of the refinery’s early-stage material requirements and is structured over an initial multi-year period.
Kwinana Cobalt Refinery Progresses with Feedstock Secured
The agreement between Cobalt Blue and Glencore marks a step forward in establishing throughput capacity for the Kwinana Cobalt Refinery. The facility is co-developed with Iwatani Australia (IWA) at the Kwinana-Rockingham industrial precinct and is expected to deliver cobalt sulphate for use in precursor cathode active material. The site will also produce cobalt metal for broader industrial and defence uses.
Infrastructure development is leveraging existing assets at the IWA fused zirconia operation, which allows for efficient integration and logistics. With proximity to Fremantle Port, the location provides strategic access to global markets, further anchoring the refinery’s role in regional supply chains.
Engineering and Regulatory Approvals Well Advanced
Cobalt Blue has appointed Tetra Tech and Green Values to lead engineering and permitting activities. The Broken Hill Technology Centre has been operating a pilot flowsheet since early last year, contributing to the technical validation of the planned refinery operations.
Environmental and regulatory frameworks are being observed as the project advances toward final development stages. The company has placed emphasis on aligning with Australia’s Critical Minerals Strategy, ensuring domestic processing capacity is expanded while meeting high environmental and governance standards.
Sourcing Strategy Anchored in ESG Compliance
COB and IWA have reaffirmed their commitment to environmental, social, and governance criteria, outlining clear standards for feedstock sourcing. Material procured under the agreement adheres to global certifications related to responsible production practices.
The partners intend to avoid supply from any entities that contravene international regulations, including US Foreign Entities of Concern requirements. In addition to the current contract, discussions are ongoing with other domestic and international suppliers to meet remaining feedstock demands.
Corporate Direction Includes Name Change and Expanded Projects
Cobalt Blue's broader development portfolio includes the Broken Hill Cobalt Project, Halls Creek Project, and the ReMine+ program targeting waste stream recovery. These initiatives are designed to support long-term output in line with demand for critical minerals across industrial sectors.
The company has also announced plans to change its name to Core Blue Minerals Ltd, pending shareholder approval. This rebranding reflects a broader corporate focus on cobalt and other critical materials positioned within strategic markets. The continued progression of the Kwinana Cobalt Refinery positions the company within the national and global battery supply chain framework.
