Askari Metals Unveils Robust Polymetallic Mineralisation at Uis Project, Namibia
Askari Metals reports strong Phase 1 trenching results at its 100%-owned Uis Project, confirming continuous high-grade polymetallic mineralisation including tin, lithium, tantalum, rubidium, and caesium. These findings bolster confidence ahead of planned drilling in H2 2026.
- Phase 1 trenching confirms continuous polymetallic mineralisation at OP Pegmatite Target
- High-grade tin intercepts up to 8,340 ppm and lithium oxide up to 0.57% Li2O
- OP Pegmatite Target extends over 2.2km strike length with widths of 15-30m
- Results validate historical data and support maiden resource drilling planned for H2 2026
- Strategic location near operating Uis Tin Mine and Walvis Bay Deepwater Port
Strategic Location and Project Overview
Askari Metals Limited (ASX:AS2) has released promising assay results from its Phase 1 trenching program at the OP Pegmatite Target within its wholly owned Uis Project in Namibia. Situated adjacent to the operating Uis Tin Mine, owned by Andrada Mining Limited, the Uis Project is strategically positioned in a proven mining district with excellent infrastructure access, including proximity to the Walvis Bay Deepwater Port less than 230 kilometres away.
The Uis Project covers a significant corridor of interest with multiple pegmatite targets, including OP, PS, DP, and K9, the latter of which has never been sampled or drilled before. The recent trenching campaign systematically tested these targets, with a focus on the OP Pegmatite Target, which extends over 2.2 kilometres in strike length and exhibits widths typically between 15 to 30 metres.
Encouraging Polymetallic Mineralisation Confirmed
Phase 1 trenching at the OP Pegmatite Target has confirmed continuous polymetallic mineralisation, with standout assay results including tin concentrations peaking at 8,340 parts per million (ppm), lithium oxide grades up to 0.57%, tantalum reaching 299 ppm, rubidium at 2,380 ppm, and caesium at 354 ppm. These grades are comparable to those of the adjacent Uis Tin Mine, which hosts a JORC-compliant mineral resource estimate of 77.51 million tonnes grading 0.79% lithium oxide, 0.15% tin, and 82 ppm tantalum.
The trenching program involved 135 trenches totaling over 7,200 metres, with channel samples collected on approximately 40-metre spacing. This systematic approach has generated a robust dataset that enhances drill targeting and resource definition efforts. Importantly, the mineralisation is near surface, although surface weathering may have affected lithium and caesium grades, suggesting that drilling into fresh rock could reveal even higher concentrations.
Validation of Historical Data and Next Steps
The recent results validate historical exploration data, including previous rock chip sampling and reverse circulation drilling, which had identified high-grade mineralisation but were limited by insufficient targeting information. The trenching has overcome these limitations by exposing the pegmatite and its splays, which were previously obscured by gravel and calcrete cover.
Askari Metals plans to commence a follow-up reverse circulation drilling program in the second half of 2026 to test the true thickness and extent of the mineralised pegmatites. This drilling will be critical to advancing towards a maiden resource estimate for the Uis Project later this year. Additional assay results from the PS and K9 targets are expected in April 2026, which will further inform exploration strategies.
Broader Market and Strategic Implications
The Uis Project’s polymetallic nature, encompassing critical minerals such as tin, lithium, tantalum, rubidium, and caesium, positions it well within the growing global demand for these commodities, particularly in technology and clean energy sectors. The proximity to existing mining operations and infrastructure enhances the project’s economic attractiveness.
With tin prices currently hovering around US$46,000 per tonne and having reached highs of US$57,000 per tonne, the potential for a significant polymetallic resource at Uis could offer substantial upside for Askari Metals and its shareholders. The company’s strategic partnership with lithium industry leader Huayou Cobalt further underscores the project’s potential significance.
Bottom Line?
Askari Metals’ Uis Project is rapidly evolving into a strategic polymetallic asset, with upcoming drilling set to unlock its full resource potential.
Questions in the middle?
- How will the upcoming RC drilling refine the understanding of mineralisation thickness and continuity?
- What are the potential economic impacts of integrating tin, lithium, tantalum, rubidium, and caesium in a single resource?
- How might market fluctuations in critical mineral prices influence the project's development timeline?
