Highlights

Otavi in Namibia remains the central copper-silver-gold exploration focus.
An April 2026 company announcement outlined a AUD 28 million Capital raising for Otavi work.
The 2026 programme includes drilling and resource definition across several Otavi prospects.
Further assays, interpretation and resource-estimate work remain important milestones.

Midas Minerals Limited (ASX:MM1) is an Australian-listed mineral explorer focused on copper, silver and gold opportunities in Namibia. Its Otavi Copper Project is the principal focus of its 2026 drilling and technical programme, while the company also retains exploration interests elsewhere. Work at Otavi spans established mineralised areas and additional prospects, with the distinction between reported drilling intersections and formally classified resources remaining central to interpreting progress.

Otavi Project and the Resource Starting Point

Midas Minerals Limited (ASX:MM1) describes Otavi as a project covering approximately 1,776 square kilometres in Namibia. The company identifies T-13, Deblin and Spaatzu among the areas attracting exploration attention. Its official project information records an initial Inferred Mineral Resource for the T-13 deposit of 10.5 million tonnes at 1.6% copper and 21 grams per tonne silver, announced in April 2026. An Inferred Resource represents geological estimates with a defined confidence classification; it is not a statement of material already mined or a commitment to develop a commercial operation.

The larger licence area creates multiple potential targets, but the scale of tenure alone does not establish the size or economic value of any discovery. Resource definition requires adequate drilling, geological interpretation and formal reporting.

Drilling Across Hartbeespoort and Spaatzu

Exploration during 2026 has extended beyond the original T-13 resource area. A 9 November 2026 company announcement reported initial reverse-circulation drilling results from Hartbeespoort, another prospect within Otavi. The announcement described shallow copper mineralisation, with gold and silver also part of the geological assessment. These early results provide information for future targeting; they do not establish a Hartbeespoort mineral resource.

Midas Minerals Limited (ASX:MM1) has also been drilling at Spaatzu and Deblin. Such programmes are designed to establish whether mineralisation is sufficiently continuous to support formal estimates. Additional assays, follow-up drilling and geological modelling are needed before results from separate holes can be treated as a defined deposit.

Funding Directed Towards Exploration

In April 2026, Midas announced firm commitments for a AUD 28 million Placement to advance Otavi exploration, drilling and initial feasibility work, as well as general working capital. That announcement described intended uses of funding, not evidence that all the proposed activities had been completed. It also identified diamond drilling at T-13 and reverse-circulation drilling at Spaatzu as part of the work then under way.

For Midas Minerals Limited (ASX:MM1), exploration expenditure must be considered alongside the timing of assay returns, technical studies and future funding requirements. Raising capital can support a broader programme, but cash availability does not remove geological uncertainty or guarantee a mine development decision.

Resource Work and Execution Considerations

The next meaningful measures are the publication of complete assay results, definition of mineralised geometry, and any new or updated Mineral Resource Estimates accompanied by the required technical disclosures. The Hartbeespoort work is at an early exploration stage, while the T-13 estimate provides a separately reported resource reference point.

Midas Minerals Limited (ASX:MM1) must also manage operating and permitting requirements in Namibia, drilling schedules and the costs of continuing technical assessment. Copper, silver and gold exposure may shape the commercial context, but metal price assumptions cannot replace geological evidence. Planned estimates remain targets until released in formal company reports.

Key Insights

Midas Minerals Limited (ASX:MM1) has progressed Otavi exploration during 2026 through work on established targets and newer prospects, alongside a capital raising intended to support the programme. Further assay results and properly reported resource updates, rather than isolated drilling intervals, will help establish the scale of mineralisation and the next technical steps.
