Patagonia Lithium Reports Promising Results from Cilon Project in Argentina

October 2, 2026 Margaret Calloway 3 min read

Details from Well 8 Testing

The drilling at Well 8 reached a depth of 200 metres with six packer tests completed to assess the aquifer’s potential. The flow rates varied, achieving a maximum of 450 litres per hour. Specific gravity measurements ranged from 1.04 to 1.06 g/cm³, with the highest recorded during the sixth test. Patagonia Lithium’s Executive Chairman, Phillip Thomas, expressed optimism about the aquifer’s strength and the consistent pumping rates achieved during these tests.

These results are part of a broader exploration strategy, as the company plans to extend drilling to 210 metres for the next packer test. The information gathered will contribute significantly to updating the project’s mineral resource estimate and conducting subsequent scoping studies.

Significance of Cilon Project in the Lithium Landscape

The Cilon Lithium Project is situated within the Salar de Jama in Jujuy Province, an area known for its rich lithium deposits. Patagonia Lithium holds a 100% interest in the project through its subsidiary, Patagonia Lithium SA. The project spans approximately 19,500 hectares, and its development is considered crucial amid growing demand for lithium, a key component in electric vehicle batteries and renewable energy storage systems.

The project’s progress has been bolstered by the completion of necessary environmental assessments, paving the way for drilling permits. As global industries increasingly shift towards sustainable energy solutions, the strategic significance of projects like Cilon cannot be understated.

Comparison with Previous Findings

Previous drilling at Well 8 had reached a depth of 485 metres, with earlier tests recording flow rates up to 705 litres per hour. Lithium concentrations increased with depth, starting at 104 ppm at shallow levels and reaching 232 ppm at deeper intervals. These findings suggest a rich lithium resource that could be economically viable.

Porosity tests indicated a total porosity of 15%, with an average drainable porosity of 5.9%. Notably, one zone was reported to contain 60% free fluid in pore space, indicating significant potential for brine extraction. A planned 72-hour pump test, following the installation of a slotted PVC liner, is expected to provide further insights into the reservoir’s capabilities.

Outlook for Patagonia Lithium

The results from Well 8 will be integral to updating the mineral resource estimate and conducting a comprehensive scoping study. These efforts are key to determining the project’s commercial viability and planning future development phases. As the lithium market continues to expand, driven by the global transition to electric vehicles and renewable energy, Patagonia Lithium’s Cilon Project is strategically positioned to capitalize on these trends.

In the coming months, the company plans to continue its exploration and testing activities to further delineate the resource. The information obtained will be critical in shaping Patagonia Lithium’s development strategy and positioning the company as a significant player in the lithium mining sector. Investors and industry stakeholders will be keenly watching the project’s progress, anticipating its impact on the broader lithium market landscape.
