Askari Metals’ Uis Soil Survey Is Done, but the Assays Are Not

Askari Metals (ASX: AS2) has finished soil sampling across its entire EPL 7626 licence at the Uis project in Namibia, yet not one assay has been released. A completed survey is not a result, and the real information sits in what happens between sampling and drilling.

The licence lies next to Andrada Mining’s operating Uis tin mine, with tin trading near US$54,000 per tonne in early October 2026. AS2 itself trades at about 0.8 cents, giving it a market capitalisation near $6.9 million, so the potential upside and the risks are both large.

Here is a framework for judging what a soil anomaly can and cannot tell you, and which milestones to watch next.

What is Askari actually looking for beneath the cover at Uis?

The licence-wide soil survey on EPL 7626 is finished. The assays are not.

Still pending Samples must be prepared and analysed, then integrated with mapping, structure, geophysics and hyperspectral data before any targets are ranked.

The grid itself has changed over time:

1. An initial concept of 200 x 200 m spacing.
2. A redesign to 400 x 40 m after overburden cover caused problems (June 2025 update).
3. About 75% complete in early September 2026.
4. Completed in early October 2026.

The redesign shows that cover is a real obstacle at EPL 7626. The tighter spacing signals care, but it also signals a higher cost to resolve each target.

Soil sampling is one step in a wider sequence of mineral exploration methods, from mapping and geophysics through to trenching and drilling, and each stage filters targets before the next, more expensive one begins.

The pegmatite target

The survey tests for tin, lithium, tantalum, caesium and rubidium. Together they point to buried lithium-caesium-tantalum (LCT) pegmatites, which are coarse-grained igneous rocks that can concentrate these metals, and to extensions of systems tied to Andrada’s mine. Andrada’s contained tin production rose 13% to 576 tonnes in the first half of its 2027 financial year, but that proximity is context, not proof.

Executive director Gino D’Anna describes Uis as developing into a polymetallic pegmatite project. Other licences, EPL 7345 and EPL 8535, remain in active exploration, with trenching at Kestrel and RC drill targeting at DP, PS, K9 and OP.

The gold target

EPL 7626 also sits on an upper structure connecting to the Okondeka Fault Zone. That zone hosts WIA Gold’s Kokoseb deposit and Ongwe’s Manga discovery, so the gold angle is a second result still outstanding from the same soil samples.

How soil geochemistry flags a pegmatite you cannot see

In the data, the signal looks like a cluster: several elevated elements sitting together on a map. Explorers look for clusters rather than single readings because a buried pegmatite leaks a halo of trace elements upward into the soil, and one high value can be noise.

Rubidium and caesium substitute for potassium as pegmatites evolve. That produces a low K/Rb ratio, which suggests an evolved LCT system rather than ordinary granite.

The method has four limitations:

• Soil can be decoupled from deeper pegmatites under thick transported cover.
• Element mobility differs, so weathering and hydrology can distort ratios.
• K/Rb only means something when the underlying rock is known.
• Laboratory validation is needed before drilling decisions.

Geochemical data quality matters as much as the anomaly itself, since sample handling, standards and duplicate checks determine whether an elevated reading is a genuine signal or an analytical artefact.

In tin-tantalum belts such as Uis, those two metals are often better soil vectors than lithium. A strong tin-tantalum anomaly with weak lithium is therefore not necessarily a disappointment, and missing lithium should not be read as a failed survey. Soil sampling is low cost, with trenching to follow on high-priority targets, which makes it a screen rather than a verdict.

What do nearby soil-to-drill discoveries really show?

Manga began as a regional soil grid in the fourth quarter of 2024, outlining an anomaly about 4.5 km x 1 km. Rock chips later returned up to 19.75 g/t Au and infill soils up to 200 ppb Au, and scout RC drilling hit wide sulphide zones. That is roughly 1.5-2 years from first anomaly to drilled discovery.

Nguni moved faster. Found in May 2026 as a gold-in-soil anomaly about 5 km long with values up to 1.3 g/t Au, it was reported to have moved to drilling within months.

Grade reality check Manga’s scout drilling returned 138 m at 0.22 g/t Au, a wide intercept at modest grade.

Kokoseb is the benchmark on the same fault zone: 105 Mt at 0.96 g/t open-pit and 7.9 Mt at 2.2 g/t underground Inferred. What the comparables tell you is that this belt responds quickly to soil work, but wide, low-grade intercepts mean “discovery” and “economic deposit” are different things. Askari sits mid-path, and the comparison is context rather than a forecast.

The risks that sit between a soil anomaly and a drill hole

Few soil anomalies become economic deposits. Cover and dispersion already forced a tighter grid at EPL 7626, and the nugget effect, where sporadic high-grade samples mislead, means extreme rock-chip values deserve little weight.

• Funding and dilution: with a market capitalisation of about $6.926 million, repeated capital raises are likely until a discovery proves itself.
• Competition: more explorers chasing the same corridors can tighten access to rigs, licences and skills.
• Policy: Namibian export rules for unprocessed critical minerals are an unconfirmed risk, and should be treated as such.

The path from here runs in sequence:

1. Assay release.
2. Integration with mapping, geophysics and hyperspectral datasets.
3. Ranking of drill-ready targets.
4. Trenching and rock chips on the best of them.
5. Drilling.

Treat the soil results as a screening filter whose value depends on lab validation and ranking, not as evidence of a deposit. Milestones such as Kestrel trenching, mapping on EPL 7345 and EPL 8535, and RC targeting separate real progress from promotion.

Hyperspectral satellite detection is increasingly used to map alteration minerals and pegmatite signatures, which is why such datasets are layered over soil results to rank targets where cover obscures the surface.

Reading the next Askari announcements with the right expectations

The survey is a necessary but early step, and its worth depends on assays, integration and ranking. Three signals matter most: when assays are released, whether tin and tantalum cluster more strongly than lithium, and how drill targets are ranked.

Until those arrive, this remains speculative exploration, and the decision point is whether the data converts into drill-ready targets.
