Askari Metals Limited (ASX: AS2) (“Askari” or “the Company”) has delivered a strong update from its 100%-owned Uis Project in Namibia, confirming continuous high-grade polymetallic mineralisation at the PS Pegmatite Target. The latest Phase I trenching results reinforce the project’s growing potential as a significant critical minerals asset, with exposure to tin, lithium, tantalum, rubidium and caesium.
The announcement marks another step forward for the Company as it advances towards drilling and a maiden JORC (2012) Mineral Resource estimate.

Strategic Location and Project Overview
The Uis Project sits within a highly prospective pegmatite belt in Namibia, adjacent to the operating Uis Tin Mine. The project benefits from established infrastructure, including proximity to the Walvis Bay Deepwater Port, located less than 230km away via sealed roads.
The Company holds a dominant land position spanning approximately 380 km², covering multiple pegmatite targets, including OP, PS, DP, and K9. These targets have already demonstrated encouraging mineralisation through historical exploration and recent trenching programs.

Strong Results from Phase I Trenching
The Phase I trenching program at the PS Pegmatite Target has successfully confirmed continuous polymetallic mineralisation across a substantial strike length.
Key assay highlights include the following:
- Up to 6,670 ppm tin (Sn)
- 0.49% lithium oxide (Li₂O)
- 465 ppm tantalum (Ta)
- 2,020 ppm rubidium (Rb)
- 134 ppm caesium (Cs)
The program included systematic trenching at approximately 40m spacing, generating a robust dataset to support future drill targeting.
Executive Director Mr Gino D’Anna stated:
“Phase I trenching at the PS Pegmatite Target continues to build on the momentum achieved from the OP and DP trenching results, again confirming high-grade continuous polymetallic mineralisation across these targets at the Uis Project in Namibia.”
Geological Continuity and Scale Potential
The PS pegmatite system has been mapped over a ~260m strike length, with an additional ~140m parallel pegmatite, indicating a sizeable mineralised system. Importantly, mineralisation occurs along the entire pegmatite length and across its width.
The Company believes these results validate earlier exploration and significantly improve confidence in the geological model.
Mr D’Anna added:
“Mineralisation occurs along the entire pegmatite length and across its width with varying concentrations returning results of up to 6,670 ppm Sn, 0.49% Li₂O, 465 ppm Ta, 2,020 ppm Rb and 134 ppm Cs.”

Tin Mineralisation Strengthens Project Economics
Tin results from the trenching program highlight strong mineralisation, with several high-grade intercepts across the pegmatite system. Notable intersections include:
- 3.14m @ 3,577 ppm Sn
- 5.32m @ 1,249 ppm Sn
- 4.95m @ 1,135 ppm Sn
These grades compare favourably with the nearby Uis Tin Mine, which has an average grade of approximately 0.15% Sn.
The proximity of the PS target to existing mining operations further enhances its development potential.

Lithium Adds Significant Upside
Lithium mineralisation at the PS target also shows promising results, with several intercepts exceeding the commonly used cut-off grade of 0.25% Li₂O for spodumene pegmatites.
Key intercepts include:
- 4.55m @ 0.40% Li₂O
- 1.60m @ 0.39% Li₂O
- 0.95m @ 0.43% Li₂O
The presence of lithium alongside tin enhances the polymetallic value proposition of the project.
The Company noted that lithium mineralisation aligns well with previous drilling results, suggesting consistency between surface and subsurface mineralisation.
Tantalum, Rubidium and Caesium Enhance Polymetallic Profile
The trenching program also confirmed strong tantalum mineralisation across the entire pegmatite system, with grades reaching up to 465 ppm Ta.
Rubidium results averaged around 0.10% Rb₂O, comparable to global benchmark projects, while caesium mineralisation, though lower at surface, remains encouraging due to potential enrichment at depth.
Mr D’Anna commented:
“These results not only validate the previously limited exploration, they also generate robust, high-confidence drill targets.”

Advancing Towards Drilling and Resource Definition
The Company has outlined an extensive exploration roadmap aimed at unlocking the full potential of the Uis Project. Planned activities include:
- Reverse circulation (RC) drilling across OP, PS, DP and K9 targets
- Maiden diamond drilling at the spodumene-rich K9 pegmatite
- Soil and geochemical surveys across additional licences
- Phase II trenching programs
Drilling is expected to commence in H2 2026, initially focusing on the OP target before expanding across the broader project area.
Mr D’Anna stated:
“We plan to move the Uis Project into the next phase of development, through rigorous systematic drilling designed to confirm the scale of the pegmatites and deliver a maiden JORC (2012) Mineral Resource estimate.”
Building a District-Scale Critical Minerals Asset
The Uis Project continues to emerge as a high-grade, district-scale polymetallic system. Its exposure to multiple critical minerals positions the Company favourably within global supply chains, particularly as demand for battery and technology metals continues to grow.
The combination of scale, grade and infrastructure access makes the project highly attractive from both a development and strategic standpoint.
Share Price Activity (ASX: AS2)
As at 12:25 pm, 6th April, 2026, the share price activity of the Company was the following:
- Last Price: $0.009
- 1-Year Performance: +2.53%
- Market Capitalisation: $6,943,444
Investors’ Outlook
Askari Metals Limited continues to build strong momentum at its Uis Project, with Phase I trenching delivering compelling evidence of a large-scale polymetallic system. The confirmation of continuous mineralisation across multiple pegmatites significantly de-risks the project ahead of drilling.
The upcoming RC and diamond drilling campaigns represent key catalysts, with the potential to define a maiden JORC resource and unlock substantial shareholder value. Additionally, pending assay results from the K9 target could further enhance the project’s overall resource potential.
With exposure to critical minerals such as lithium, tin and tantalum, the Company is well-positioned to benefit from long-term global demand trends. As exploration progresses and drilling commences, investors can expect a steady flow of news and potential value-accretive milestones.
The Company remains committed to advancing the Uis Project through systematic exploration while keeping shareholders informed every step of the way.
