Askari Metals (ASX: AS2) has confirmed continuous polymetallic mineralisation during Phase 1 trenching across the high-priority PS pegmatite target at its Uis project in Namibia.
The target sits within a defined corridor of interest alongside the OP, DP and K9 targets, all of which display characteristics typical of fertile lithium-caesium-tantalum (LCT) pegmatites.
This includes a high degree of fractionation and zonation, along with key lithium accessory minerals such as varieties of albite, coloured tourmaline, and green mica.
A total of 14 trenches for 272 metres at PS returned peak results of 6,670 parts per million tin, 0.49% lithium oxide, 465ppm tantalum, 2,020ppm rubidium, and 134ppm caesium, providing a dataset to support drill targeting and future resource definition.
Trenching exposed the target over 260m at surface, with a parallel pegmatite extending approximately 140m and potential extensions at depth to be tested during a planned drilling campaign.
Validation of Historical Samples
The latest results validate historical mapping and rock chip sampling at the PS pegmatite target that returned values of up to 1.63% tin oxide, 639ppm tantalum oxide, 0.27% rubidium oxide, and as much as 3.05% lithium oxide.
Past reverse circulation drilling by Askari also returned high-grade intercepts of 4m at 0.16% tin oxide including 1m @ 0.26%, 4m at 314ppm tantalum oxide including 1m at 695ppm, and 2m at 0.30% rubidium including 1m at 0.38%.
The PS target has previously delivered high grades of tin, tantalum, lithium, and rubidium mineralisation from surface mapping, rock chip sampling, and two phases of reverse circulation (RC) drilling.
Askari has planned its next phase of RC drilling at Uis for the second half of 2026.
Work will start at the OP target, then expanded to include DP, PS, and the spodumene-rich K9 pegmatite target that will be see its maiden diamond drilling campaign.
Uis Momentum Building
Askari executive director Gino D’Anna said the Phase 1 results had built on momentum achieved from exploration at the nearby OP and DP targets.
“These results not only validate the previously limited exploration, they also generate robust, high-confidence drill targets,” he said.
“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.”
“The results strongly indicate a significantly mineralised system that warrants further exploration as we target a maiden resource at Uis later this year.”
