• Uvre’s first pass exploration at South Pass uncovers several prospective outcropping pegmatites
  • Observation of lepidolite within the project area confirms potential for lithium-bearing minerals
  • 100+ rock chip and soil samples collected and sent for laboratory analysis for Lithium and Rare Earths


Special Report: First pass field exploration at Uvre’s recently secured South Pass project in Wyoming has uncovered prospective signs for lithium – including lepidolite – and several large outcropping pegmatites.

South Pass has not been previously explored for lithium despite having favourable geological characteristics such as outcropping pegmatites and dykes that occur in large swarms which have the potential to contain lithium-caesium-tantalum pegmatites.

This potential was identified from historical United States Geological Survey (USGS) geological mineral reports and elevated lithium detected in historical regional multi element chemical sampling which was taken for the purpose of precious metal exploration.

Uvre (ASX:UVA) believes the project has excellent potential due to the extensive exposures of outcropping pegmatites visible from satellite imagery and confirmed during field reconnaissance work.

Pegmatites up to several hundred metres long were observed in the vicinity of nearby faults and the South Pass greenstone belt.

Similar pegmatites in the district have been found to be enriched in columbite, tantalite, microcline, tourmaline, beryl and garnet, with accessory minerals including lithium bearing lepidolite and spodumene.


Lepidolite occurrence confirms potential for lithium pegmatites

UVA has now completed reconnaissance exploration sampling over about half of the swarms of untested pegmatites at the project, collecting 165 rock chip samples and 33 soil samples for laboratory analysis.

Notably, lepidolite – a significant lithium mineral – was observed within the project area, confirming the potential for lithium-bearing pegmatites.

“Our geology team were able to collect a significant number of rock and soil samples before the snow fell which is a great first pass assessment. They were encouraged by the minerals they observed in several of the large-scale outcropping pegmatites and were able to visit approximately half of the known pegmatites,” UVA managing director Peter Woods said.

“We plan to appraise the other half after the snow melts in Q1/Q2 2024.

“The South Pass Lithium Project has a significant number of outcropping pegmatites to test which may have the potential to be fertile for lithium mineralisation.

“We eagerly await laboratory results from this first pass reconnaissance sampling to allow us to prioritise and carry out a more systematic sampling program and vector into the fertile pegmatites as we rapidly advance this project in 2024.”
