Latest Pump Testing News

Patagonia Lithium has corrected its Well 8 announcement, confirming a 72-hour pumping rate of about 2,043 litres per hour and rapid aquifer recovery at its Cilon project in Argentina. The pumped brine is estimated to have contained 29kg to 33.7kg of lithium, although the figure is an inferred assay-based estimate rather than a resource or production measure.

PTR Minerals has confirmed water-bearing aquifers at all three palaeochannel targets tested near its Rosewood Titanium Project, supporting the proposed gravity-based processing route. The result improves the project’s water supply outlook, but yield, quality and long-term sustainability still require testing.

Patagonia Lithium has reported 15% total porosity and substantial free-fluid storage from Cilon Well 8, strengthening its interpretation of the aquifer’s pumping potential. The evidence is encouraging but remains incomplete, with four core results, further BMR Gamma data and a 72-hour pump test still outstanding.

Pursuit Minerals has started its first diamond hole at the Demasía tenement, testing whether lithium-bearing brines extend beyond the existing 1.264 million tonne LCE resource at Rio Grande Sur. Early packer tests recovered brine at shallow depths, but lithium assays are still pending.

Patagonia Lithium’s Well 7 delivers strong porosity alignment between core and gamma surveys, with lithium levels near project averages. Preparations for Well 8 pump testing advance, while plans for Well 9 await regulatory approval.

American Uranium has launched extensive aquifer pump testing at its Lo Herma Mine Unit 1, reinforcing progress toward in-situ recovery development and feeding data into a Q4 2026 Scoping Study.

Patagonia Lithium’s Well 8 at the Cilon project hit basement at 485m, delivering promising lithium assays and robust brine flow rates. Plans for porosity testing and a 72-hour pump test are underway to refine resource estimates.

American Uranium has lifted its Lo Herma uranium resource to nearly 10 million pounds U3O8, with a 72% jump in Indicated Resources and a stronger base ahead of a Q4 2026 scoping study.

Patagonia Lithium has received an interim technical report confirming promising porosity and lithium assay results from seven wells, setting the stage for a final resource estimate after well eight completion.

Patagonia Lithium (ASX:PL3) reported solid progress in its June quarter, hitting key milestones in drilling, pump testing, and resource modelling at its Argentine lithium brine projects, supported by a strong cash position following recent capital raises.

American Uranium Limited (ASX: AMU) advanced its Lo Herma ISR uranium project in the June 2026 quarter, completing a $2.64 million placement, delivering promising drilling outcomes, and preparing for large-scale pump testing ahead of a Q3 resource update.

Patagonia Lithium's Well 8 at the Formentera/Cilon project in Argentina has delivered impressive packer test flow rates up to 705 L/hr at 257m depth, alongside rising specific gravity and total dissolved solids that hint at promising lithium concentrations.
