Patriot Battery Metals Inc (opens in a new tab). has discovered (opens in a new tab) significant cesium mineralization at its CV13 Pegmatite, part of the Shaakichiuwaanaan Property in Quebec. This is a rare and potentially valuable find, as cesium is a highly sought-after critical mineral with limited global production.

Key findings include:

• High cesium concentrations in multiple drill holes, with assays exceeding 1% Cs₂O in several locations.
• The largest cesium-rich zone aligns with the high-grade lithium Vega Zone at CV13, covering 600m x 400m and remaining open for expansion.
• The mineral pollucite, the primary ore for cesium, has been confirmed at CV13, suggesting economic potential.
• Over 140 core samples are still pending over-limit cesium analysis, meaning results could further expand the discovery.

This extremely rare cesium deposit has the potential to become a valuable by-product alongside lithium production at the property. Given the scarcity of cesium and its importance in advanced technologies, this discovery could enhance the project’s economic value.

Why This Discovery Matters

Cesium is one of the rarest critical minerals in the world, primarily found in LCT (lithium-cesium-tantalum) pegmatites. Its key applications include:

• High-precision atomic clocks power GPS and telecommunications systems.
• Cesium formate brine is used in oil and gas drilling for high-pressure, high-temperature wells.
• Advanced optics, batteries, and medical imaging (X-rays and radiation detectors).

Global production is minimal, with only a handful of active mines worldwide. The last cesium mine in Australia ceased production in 2019, leaving a potential supply gap.

This discovery is significant because most lithium pegmatites do not contain economic cesium levels. The presence of pollucite at Shaakichiuwaanaan suggests the potential for a secondary revenue stream, further strengthening the project’s economic case as Patriot advances its lithium production plans.
