The U.S. imports 100% of its required cesium, a rare mineral used in atomic clocks, GPS systems, aerospace solar technology, advanced communications networks, and high-tech defense equipment. More from Yahoo Scout That could make a high-grade cesium discovery in Ontario a potential source of new North American supply. And now it's moved from a discovery story to a development one, as Power Metals ( TSXV: PWM ; OTC:PWRMF ) advances one of the continent's few cesium-focused projects. For years, cesium occupied a niche corner of the critical minerals market. But national security has changed that. Now, governments are moving to secure supply chains, boosting defense spending and driving up growing demand for advanced communications, aerospace technologies, and next-generation computing infrastructure. At the same time, the global cesium supply has become even more concentrated . Only a handful of cesium deposits have ever been mined commercially, and most are either depleted, inactive, or controlled by Chinese interests. That backdrop helps explain why Power Metals' Case Lake projec…
