In a move poised to reshape the global supply of one of the world’s rarest critical minerals, PMET Resources has launched a high-stakes partnership with Koch Technology Solutions to unlock the commercial potential of its massive caesium discovery in Quebec.
The agreement kicks off a four-month test program aimed at converting pollucite from the Shaakichiuwaanaan project into high-value caesium chemicals—materials vital for defense systems, aerospace technologies, advanced electronics, and energy applications.
Backed by Koch, one of the largest privately held companies in the United States, the initiative signals a potential fast track into US industrial supply chains at a time when demand for secure critical mineral sources is intensifying.
At the center of the push is what PMET describes as the world’s most significant caesium discovery—both in scale and grade—positioning the company to become a dominant supplier in a tightly constrained global market.
PMET CEO Ken Brinsden underscored the stakes: "Shaakichiuwaanaan hosts what we believe to be the most significant caesium discovery globally, marked both by incredible scale and high grades – and this program represents a major step towards unlocking its full commercial potential.
"Working with Koch Technology Solutions provides access to industry expertise, including demonstrated capabilities in critical minerals, and a portfolio of innovative processing technologies."
The company is betting that advanced processing techniques developed by Koch Technology Solutions will allow it to move beyond raw extraction and into higher-margin chemical production—a shift that could dramatically boost project economics.
"Importantly, this initiative will allow us to explore pathways to produce high-value caesium chemicals, which could ultimately position PMET as a cornerstone supplier to critical industries including defence, aerospace, energy and advanced technologies.
"Through this program, PMET furthers its exposure to the significance of critical minerals in the key U.S. market, providing us with an opportunity to capture substantially greater value from this rare and strategically important discovery by working alongside a US industry participant," added Brinsden.
Koch Technology Solutions says the collaboration is designed to tackle exactly this kind of complex extraction challenge.
"This program brings together the distinct strengths of KTS and PMET to advance an innovative approach in critical minerals extraction.
"The project reflects the kind of challenge that KTS is uniquely positioned to solve, by applying our process technology and technical expertise alongside PMET to advance an approach to help unlock the value of an important critical mineral supply base," said Garrett Krall, the company’s Critical Minerals Business Leader.
The Shaakichiuwaanaan property already ranks among the largest lithium pegmatite resources globally. But it is the caesium—hosted in the CV13 pegmatite—that is drawing increasing attention. The deposit is considered the largest known in-situ pollucite-hosted caesium resource in the world, with mineralization still open in multiple zones.
Beyond traditional industrial uses, PMET is also exploring emerging applications, including next-generation solar panels where caesium could enhance energy efficiency.
