Midas Minerals has reported strong copper-silver assays from deeper infill drilling at its T-13 deposit in Namibia, including 10 metres at 11.55% copper equivalent. The mineralised zone remains open to the west as the company accelerates drilling ahead of a resource update targeted for early 2027.
- 22.6m at 6.01% CuEq, including 10.0m at 11.55% CuEq
- 33.2m at 2.51% CuEq from about 300m vertical depth
- High-grade Main Zone remains open to the west
- More than 15,000m drilled since December 2025, with 16 holes awaiting assays
- Updated T-13 resource and maiden Deblin and Spaatzu estimates targeted for Q1 2027
High-grade T-13 mineralisation extends west
Midas Minerals Ltd (ASX:MM1) has strengthened the case for a larger high-grade core at its T-13 copper-silver deposit in Namibia, with new drilling returning a 22.6-metre intersection at 6.01% copper equivalent. The interval, from 347.5 metres downhole in hole T13DD034, averaged 4.67% copper and 70.9 grams per tonne silver, including 10 metres at 11.55% CuEq, or 8.83% copper and 143.7g/t silver.
The result came from the margins of the Main Zone’s high-grade corridor, and Midas said the mineralisation remains open towards the west. The company described the intersection as stronger than anticipated, although that is management’s assessment of the drilling result rather than a new resource estimate. Estimated true thickness for the T13DD034 interval is between 90% and 95% of the reported downhole width.
Deeper drilling adds evidence of continuity
A second hole, T13DD030, returned 33.2 metres at 2.51% CuEq from 310.3 metres, including 23.6 metres at 3.11% CuEq. The result is one of Midas’ deeper holes at T-13 and points to mineralisation continuing at depth, with the estimated true width calculated at 80% to 85% of the reported interval.
The latest assays build on the company’s July T-13 drilling results, which had extended high-grade copper-silver mineralisation across the Main and West zones. The current release reports exploration results only: T-13’s existing Inferred Mineral Resource remains 10.5 million tonnes at 1.6% copper and 21g/t silver, equivalent to 2.0% CuEq, based on drilling completed before Midas acquired the project.
Resource update depends on the next assay wave
Midas has completed more than 15,000 metres of core drilling at Otavi since December 2025, with assays still pending for 16 holes. The company is continuing infill drilling across T-13 before an updated Mineral Resource Estimate targeted for the first quarter of calendar 2027. Initial estimates for the Deblin and Spaatzu deposits are planned for the same period.
The pace of work is increasing: seven rigs are currently operating across the 1,776-square-kilometre Otavi project, and an eighth rig is expected to arrive this week. Midas also says the West Zone has returned strong copper-silver mineralisation in limited drilling, but further work there will follow completion of Main Zone infill drilling.
Copper equivalent grades carry stated assumptions
The reported CuEq figures use copper priced at US$11,906 per tonne and silver at US$2.254 per gram, alongside assumed 85% recoveries for both metals based on 2024 sighter metallurgical testwork. Those assumptions provide a consistent way to present the intersections, but they are not a feasibility study or proof that the mineralisation can be economically recovered at scale.
Bottom Line?
The immediate test is whether pending assays confirm the western and deeper continuity strongly enough to translate impressive intercepts into a materially larger, well-supported resource in Q1 2027.
Questions in the middle?
- Will the 16 pending assays confirm the high-grade zone’s continuity beyond the latest holes?
- How much of the westward and deeper mineralisation will qualify for inclusion in the updated T-13 resource?
- Will future metallurgical work support the 85% recovery assumptions used in the CuEq calculations?
