"The combined backgrounds of these two individuals in critical minerals, major project delivery and contract mining enable Locksley to address one of the most pressing US supply constraints: the absence of large-scale commercial antimony processing capacity," said Pat Burke, chairman of Locksley. "Their appointments significantly enhance our executive capability at a pivotal moment for Locksley, supporting our strategy to transform the historic Desert Antimony Mine into a modern, fully integrated mine-to-market supply chain for 100% Made in America Antimony."

Ms. Matthews is a highly accomplished executive leader with more than two decades of experience delivering significant and capital-intensive projects in the resources and infrastructure sectors. She has held leadership roles in the execution of BHP's US$3.8 billion South Flank Project and Iluka's A$1.8 billion Eneabba Rare Earths Refinery, Australia's first fully integrated rare earths refinery. She brings extensive expertise in governance, stakeholder alignment, cost optimization and regulatory engagement, alongside her proven record of aligning large scale projects with both commercial and government priorities.

Mr. George is an experienced senior executive with a global background spanning all phases of project execution across mining, energy and infrastructure. His past experience includes major projects with WSP, Fortescue, Mineral Resources, Thyssenkrupp and Ausenco, working with leading companies such as Vale, BHP and Hancock Prospecting.

His technical breadth and expertise in rapid project delivery, capital efficiency and large-scale project execution provide Locksley with the operational discipline and agility required to advance the Desert Antimony Mine project on an accelerated schedule.

The company also announced that Julian Woodcook has resigned as technical director to focus on his Managing Director role at Viking Mines Ltd. He has been instrumental in the rapid advancement of the Company's Mojave Project and will continue to offer strategic guidance to the company in a technical consulting capacity.
