  • Licensing, binding offtake arrangements and the remaining funding package are important outstanding steps.

Viridis Mining and Minerals Limited (ASX:VMM) is an ASX-listed critical-minerals explorer and developer whose principal focus is the Colossus rare earths project in Minas Gerais, Brazil. The company is working to advance the project from technical studies toward construction and production. Its disclosures during 2026 have covered processing trials, feasibility work, finance arrangements and engineering appointments.

Colossus Moves Beyond Early Technical Studies

Viridis Mining and Minerals (ASX:VMM) reported an updated Colossus mineral resource in July 2026 of 473 million tonnes at 2,505 parts per million total rare earth oxides (TREO). This is a mineral resource estimate, rather than a statement of the quantity that can be mined economically. The project targets rare earth products used in industrial and magnet supply chains, while its ultimate scale will depend on processing performance, construction execution and commercially viable product sales.

In July, ASX:VMM reported that its demonstration plant had produced mixed rare earth carbonate. Earlier metallurgical work indicated recoveries above the assumptions used in its pre-feasibility study. The company also submitted an application for an Installation Licence in Minas Gerais, which is distinct from obtaining that approval.

Feasibility Work and Project Economics

On 20 August 2026, Viridis Mining and Minerals (ASX:VMM) announced completion of a definitive feasibility study for Colossus. Its reported economic assessment included an after-tax net present value of approximately US$1.20 billion and an after-tax internal rate of return of 36.4%. They depend on stated assumptions about rare earth prices, capital spending, operating performance and development timing.

The feasibility study provided a basis for engineering and financing discussions. ASX:VMM therefore remains exposed to the execution risks typical of projects before commercial production.

Financing and Engineering Milestones

Viridis Mining and Minerals (ASX:VMM) announced up to US$120 million of strategic equity funding commitments in August 2026. On 9 September, it reported approval of a R$77.5 million financing facility from Brazil’s development bank BNDES for eligible research and processing activities. The company stated that its remaining senior debt requirement for Colossus was approximately US$280 million. Approval of one facility should not be interpreted as confirmation that the entire construction funding package is in place.

On 10 September, ASX:VMM identified Sedgman and Blossom as preferred engineering, procurement and construction management partners. The company also described early equipment procurement and detailed execution planning. Its quarterly activities and cash-flow report, released on 27 October, recorded further progress and reported quarter-end cash of A$119.7 million.

Approvals, Offtake and Development Risks

A commercial project depends on regulatory permissions, construction and commissioning, suitable utility infrastructure and reliable product recoveries. ASX:VMM has also described discussions with Solvay concerning product offtake and technical cooperation. The previously disclosed letter of intent was non-binding; commercial commitments should be distinguished from preliminary negotiations.

The next relevant company disclosures include the status of the Installation Licence, the terms of any binding offtake agreement, remaining senior debt arrangements and the timing of a final investment decision. Viridis has identified 2028 as a production objective, but projected dates remain contingent on execution and approvals.

Key Insights

Viridis Mining and Minerals (ASX:VMM) has progressed Colossus through resource work, demonstration processing, a definitive feasibility study and initial engineering and financing steps in 2026. The distinction between planned production and funded, permitted operations remains central to understanding the company’s position. Its October quarterly report provides a later reference point than the original July disclosures, while further milestones will indicate how the project advances toward construction.
