Askari Metals Uncovers High-Grade Critical Minerals in Namibia

Askari Metals Strikes Gold with High-Grade Critical Minerals at Uis Project

Askari Metals (ASX: AS2) has delivered exceptional Phase 1 trenching results from its DP Pegmatite Target at the strategic Uis Project in Namibia. The results confirm the presence of Askari Metals high-grade critical minerals across multiple valuable commodities.

The results showcase peak values of 3360 ppm tin, 1.25% lithium oxide, 364 ppm tantalum, 3370 ppm rubidium, and 587 ppm caesium. Furthermore, these results position the project as a significant emerging critical minerals asset.

Located directly adjacent to Andrada Mining's operating Uis Tin Mine, the Uis Project benefits from proven geology in an established mining district. The mine hosts a substantial JORC resource of 77.51Mt @ 0.79% Li2O, 0.15% Sn and 82 ppm Ta.

In addition, the project enjoys excellent infrastructure access to Walvis Bay Port just 230km away, providing strategic logistical advantages.

Systematic Trenching Programme Delivers Robust Dataset

The Phase 1 trenching campaign represents a methodical approach to resource definition, with 135 trenches totalling 7,269m completed across the high-priority DP, PS, OP and K9 pegmatite targets. The systematic 40m spacing grid at DP generated 2,098 one-metre channel samples.

However, this comprehensive approach provides crucial geological understanding for upcoming drill targeting. The programme demonstrates Askari Metals' commitment to thorough exploration methodology.

Key DP Pegmatite Highlights

The main DP pegmatite extends approximately 700m along strike with an average surface thickness of 6m. This demonstrates meaningful scale potential that supports the case for a substantial polymetallic resource.

Understanding LCT Pegmatites: The Foundation of Critical Mineral Wealth

LCT (Lithium-Caesium-Tantalum) pegmatites represent some of the world's most valuable sources of critical minerals essential for modern technology. These geological formations occur when highly evolved granitic magmas concentrate rare elements during the final stages of crystallisation.

For instance, this process creates zones exceptionally enriched in lithium, caesium, tantalum, tin, and rubidium. The Cape Cross-Uis pegmatite belt, where Askari's project sits, is renowned globally for hosting world-class LCT pegmatites.

The belt is characterised by high degrees of fractionation and zonation. This geological setting has already proven its value through Andrada Mining's successful operation next door, providing confidence in the district's mineral endowment.

For investors, LCT pegmatites offer several advantages: they typically contain multiple valuable commodities within the same ore body, reducing mining costs. Additionally, they often occur in clusters, providing expansion potential, and tend to have favourable metallurgical characteristics.

Multiple Value Drivers Across Critical Mineral Portfolio

Tin: The Standout Performer

Tin results demonstrate exceptional consistency across the 700m strike length, with 14% of total metal content represented by tin. This directly compares to grades included in Andrada's resource model.

Notable intercepts include:

• 13.10m @ 930 ppm Sn from DPTR11
• 8.32m @ 838 ppm Sn from DPTR10
• 5.22m @ 1293 ppm Sn from DPTR09

With tin prices approaching US$50,000 per tonne and having reached US$55,000 per tonne, these grades represent significant economic potential. Moreover, tin operates in a supply-constrained market, enhancing long-term value prospects.

Lithium: Dominant Metal Content

Lithium represents the dominant commodity at 42% of total metal content, with extensive zones grading between 0.25% to 0.50% Li2O.

Key intercepts include:

• 13.45m @ 0.36% Li2O (including 5.08m @ 0.49% Li2O)
• 10.76m @ 0.37% Li2O (including 5.22m @ 0.50% Li2O)
• 9.29m @ 0.61% Li2O (including 1.85m @ 1.20% Li2O)

Importantly, these results come from semi-oxidised surface samples, where lithium's high mobility typically reduces surface concentrations. Fresh rock drilling is expected to deliver significantly higher lithium grades.

Tantalum, Rubidium & Caesium: High-Value Specialty Metals

The presence of tantalum values ranging 80-364 ppm parallels the neighbouring Uis Mine's resource grade of 82 ppm. Meanwhile, rubidium concentrations of 1000-3370 ppm compare favourably to advanced rubidium projects globally.

Caesium values reaching 587 ppm add further value to this polymetallic system. This is particularly significant as demand grows for quantum computing and specialty glass applications.

"The Phase I trenching results from the DP Pegmatite Target are highly encouraging and confirm the presence of strong, continuous polymetallic mineralisation across a substantial strike length. These results materially strengthen our confidence in the scale and quality of the mineralised system at Uis," said Gino D'Anna, Executive Director.
