Patriot Battery Metals Inc. is advancing its Shaakichiuwaanaan project by evaluating tantalum recovery from lithium waste streams. With one of the world's top tantalum pegmatites, this promising by-product opportunity could boost project economics and offer a conflict-free supply for high-tech markets.

Patriot Battery Metals Inc. has unveiled new field work at its Shaakichiuwaanaan Project in Quebec, emphasizing ongoing test programs to tap tantalum as a valuable by‐product alongside its primary lithium operation. The company’s extensive work streams have now commenced on caesium, tantalum, and gallium, with tantalum emerging as a key metal opportunity. The resource estimate for the project indicates an impressive ranking among tantalum pegmatites globally, featuring an indicated resource of 108.0 million tonnes with an average grade of 1.40% Li2O and 166 parts per million (ppm) Ta2O5, and an inferred resource of 33.3 million tonnes grading 1.33% Li2O and 156 ppm Ta2O5. Several high-grade drill intersections reported in the announcement highlight intervals such as 9.6 meters grading 2,307 ppm Ta2O5, reinforcing the prospect’s potential to deliver significant critical metal outputs. Company executives, including Executive Vice President Exploration Darren L. Smith, stress that tantalum recovery could be integrated into the existing lithium processing circuit without negatively impacting lithium outputs. Test programs conducted at SGS Canada’s Lakefield facility have already succeeded in producing initial tantalum concentrates ranging from about 12% to 19% Ta2O5. This recovery approach relies on conventional magnetic and gravity techniques—the same tried and tested methods used at prominent pegmatite operations worldwide—thus potentially de-risking the pathway to enhance overall project economics as the lithium-only feasibility study progresses toward a scheduled Q3 2025 completion. The growing global demand for tantalum, driven by high-tech applications from electronics to aerospace and quantum computing, adds further allure to the project. With the metal currently trading in refined form at around US$239 per kilogram and anticipated market growth at a compound annual rate of 4-6%, the project’s strategic positioning could supply a conflict-free source providing secure and stable supply to global markets, addressing concerns common with current producers in regions affected by geopolitical instability. Market sentiment based on the news appears mixed. On the bullish side, the project’s high-quality resource, robust initial testwork results, and the seamless integration potential of a tantalum recovery circuit into the existing lithium process suggest considerable upside for future economic returns. Moreover, the classification of the deposit among the top tantalum pegmatites globally reinforces its potential as a critical by-product opportunity. On the bearish side, uncertainties remain regarding the final recovery efficiency in scaled-up operations and the broader commodity market’s vulnerability to technological, regulatory, and geopolitical factors. Additionally, the success of the complete integration and the forthcoming feasibility study, crucial to monetizing both the primary lithium and complementary critical metals, will ultimately determine market confidence going forward.
