Ben was appointed Financial Director of Guardian Metal in December 2024. Since his appointment, he has been responsible for aspects of the Company's finance function including audit lead, financial reporting and tax planning, as well the oversight of financial and reporting processes. As such, he has played an integral role in the rapid growth of the Company, including the successful raising of over US$21 million during the course of his tenure, and the acquisition of the Tempiute Tungsten Mine & Mill ("Tempiute"). Ben will today step down as Financial Director and assume his role as a Non-Executive Director, and as Chair of the Audit Committee.

J.T. Starzecki, Executive Chair, commented:

"We are delighted to welcome Jake to the Guardian Metal team at an important stage for the Company. He brings with him a wealth of experience, including as leader of financial divisions within fast-growing, natural resource organisations, suited to Guardian Metal as we progress the development of our U.S.-based tungsten projects.

"We also express our sincere thanks to Ben who has played a central role in defining and delivering the Company's strategy to date, including equity raises and the acquisition of Tempiute. We are pleased that Ben will remain on the Board as a Non-Executive Director, allowing the Company to continue to benefit from his expertise and deep knowledge of the business, as the team delivers on our next phase of growth."
