Midas Minerals Expands High-Grade Zones at Namibia’s T-13 Deposit

Mining By Maxwell Dee 3 min read

Midas Minerals has unveiled new high-grade copper and silver drill results at its T-13 Deposit within the Otavi Copper Project, revealing an expanded footprint of premium mineralisation and a promising upgrade to its resource base.

  • High-grade copper-silver intercepts extend T-13 Main and West zones
  • West Zone reveals previously undetected higher-grade core
  • Initial Mineral Resource Estimate stands at 10.5Mt grading 2.0% CuEq
  • Six rigs active with seventh rig arriving soon
  • Updated T-13 resource estimate expected by end 2026

Infill Drilling Uncovers Strong Continuity and Expansion

Midas Minerals (ASX:MM1) has delivered another tranche of compelling assay results from its T-13 Copper-Silver Deposit at the Otavi Copper Project in Namibia. The latest diamond drilling has not only confirmed strong continuity within the high-grade Main Zone but also revealed a higher-grade core within the previously lower-grade West Zone.

Noteworthy intercepts from the Main Zone include a 30.1m interval grading 5.35% copper equivalent (CuEq), featuring 4.01% copper and 71.2g/t silver, and a 27.1m intercept at 3.98% CuEq. These results extend the footprint of the very high-grade portion of the deposit, reinforcing the deposit’s robust mineralisation continuity at depth.

West Zone Upgraded with Higher-Grade Core

The West Zone, located approximately 500 metres west of the Main Zone, has historically been considered a lower-grade satellite, averaging just 0.99% copper and 6.6g/t silver in prior wide-spaced drilling. However, recent infill drilling spaced at 80 metres has uncovered significant higher-grade intervals, including 15 metres at 3.87% CuEq and a standout 6-metre section grading 5.90% CuEq.

This breakthrough suggests the West Zone harbours a previously unrecognised high-grade core that could materially uplift the overall resource quality. The deposit’s broader 4.6-kilometre strike length now looks increasingly promising for hosting multiple high-grade zones.

Resource Base and Operational Momentum

The initial Mineral Resource Estimate (MRE) for T-13, based on pre-acquisition drilling, stands at 10.5 million tonnes grading 1.6% copper and 21g/t silver, equating to 2.0% CuEq and containing 211,000 tonnes of copper equivalent metal. Midas is actively drilling with six rigs across the Otavi Project, expecting to add a seventh imminently, aiming to sustain a steady flow of results through the second half of 2026.

Managing Director Mark Calderwood highlighted the significance of the new data, noting the “strong silver-rich bornite-chalcocite mineralisation” and the potential of the zonation pattern from chalcocite to bornite within the high-grade cores. He emphasised that this mineralogical insight could guide further exploration along the T-13 prospect, enhancing the hunt for additional high-grade ‘core zones’.

Strategic Positioning in Namibia’s Mining Landscape

Namibia ranks as a top African mining jurisdiction, supported by political stability, transparent mineral rights, and robust infrastructure. Midas’ Otavi Project benefits from this environment, with substantial exploration upside given that less than 40% of the tenure has undergone modern drilling. The company’s broader portfolio includes options on adjacent projects and other mineral prospects in Namibia and Canada, positioning it well for diversified growth.

An updated MRE for T-13 is slated for release by the end of 2026, with an initial resource estimate for the Deblin deposit expected in early 2027, underpinning a clear development pipeline.

Bottom Line?

Midas Minerals’ latest drilling at T-13 is reshaping the resource profile with high-grade expansions, setting the stage for a resource update that could recalibrate the project’s value proposition.

Questions in the middle?

  • How will the higher-grade core in the West Zone affect the overall resource classification and project economics?
  • What exploration strategies will Midas deploy to test for additional high-grade zones along the 4.6km T-13 strike?
  • How might commodity price fluctuations influence the timing and scale of development decisions at Otavi?
