en.Wedoany.com Reported - PMET Resources (ASX:PMT) has discovered high-grade lithium, cesium, and tantalum mineralization during surface exploration at its James Bay assets in Quebec, Canada, with surface sampling returning up to 16.43% cesium oxide, 2.94% lithium oxide, and 3,768 ppm tantalum pentoxide. These discoveries are located across the flagship Shaakichiuwaanaan project and regional assets including Pontois and Pontax.

Darren Smith, Executive Vice President of Exploration, stated that the new discoveries further confirm the scale and growth potential of lithium, cesium, and tantalum resources within the company's land package in the Eeyou Istchee James Bay region.

At the Shaakichiuwaanaan project, PMET discovered a new Cosma cesium-rich pegmatite approximately 22 kilometers west of the CV5 deposit. Initial grab samples returned 9.42% cesium oxide, followed by channel sampling yielding 4.4 meters grading 3.61% cesium oxide and 609 ppm tantalum pentoxide, including a higher-grade interval of 0.5 meters grading 16.43% cesium oxide.

The company also discovered the Felix spodumene-bearing pegmatite near the western margin of Shaakichiuwaanaan, with surface sampling returning 1.80% and 1.21% lithium oxide from multiple mineralized outcrops distributed over a 450-meter strike length. These discoveries, together with the Drakkar pegmatite on the nearby Pikwa asset, extend the prospective Mickel lithium-cesium-tantalum pegmatite corridor to approximately 10.5 kilometers in length.

A newly discovered Skald pegmatite on the Pontois asset returned a surface sample grading 2.94% lithium oxide. The Overload discovery at Pontax yielded 7.53% cesium oxide and 3,768 ppm tantalum pentoxide from a pegmatite dike over 50 meters long.

These discoveries stem from PMET's 2025 surface exploration program, including geological mapping, prospecting, and rock sampling. A total of 355 rock samples were collected at Shaakichiuwaanaan alone, returning values up to 4.51% lithium oxide, 16.43% cesium oxide, and 2,580 ppm tantalum pentoxide. The company also collected 69 samples at Pontois and 54 samples at Pontax, focusing on identifying new lithium-cesium-tantalum pegmatites across its regional asset portfolio.

The Shaakichiuwaanaan project hosts one of the world's largest lithium-cesium-tantalum pegmatite systems. PMET completed a feasibility study for the CV5 deposit in late 2025, yielding probable reserves of 84.3 million tonnes grading 1.26% lithium oxide. At the CV5 and CV13 deposits, combined mineral resources include 108 million tonnes grading 1.40% lithium oxide in the indicated category and 33.4 million tonnes grading 1.33% lithium oxide in the inferred category.

PMET plans to follow up on the new discoveries in 2026 with additional surface exploration, including further work at Shaakichiuwaanaan and an inaugural exploration program on the recently acquired Pikwa asset. The company is also evaluating the next phase of exploration at Pontax, where several highly mineralized pegmatite outcrops have yet to be drill-tested.
