McEwen Copper Inc., 52% owned by McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to announce the appointment of Mr. Darren King as Exploration Director. With over 35 years of international experience in all stages of copper and gold exploration across North, Central, and South America, Darren brings a wealth of expertise to his new role.

Before joining McEwen Copper, Darren served as Vice President of Exploration at INV Metals, where he made significant contributions to the successful completion of the 2018 and 2020 feasibility studies for the Loma Larga project in Ecuador, which led the company to attract a takeover from Dundee Precious Metals at a 63% premium. During his tenure, Darren also advanced regional exploration properties and ensured compliance with safety, social, and environmental standards.

Before INV Metals, Darren held the position of Mine Exploration Manager for South America at Barrick Gold Corporation, where he played an important role in developing and implementing exploration programs near multiple mines, including Lagunas Norte, Pierina, Zaldivar, and Veladero, with an approach that allowed for consistent addition of reserves and resources each year.

Over his career, Darren created innovative geological models that led to significant discoveries in the Dominican Republic, Panama, and Argentina, such as the identification of the orebodies Monte Oculto at Pueblo Viejo and Argenta at Veladero. He holds a Master of Science in Geology from South Dakota School of Mines and Technology, he is a Registered Member of Society for Mining, Metallurgy & Exploration (SME), and a Qualified Person under National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

Michael Meding, Vice President and General Manager of McEwen Copper stated, "We are delighted to have Darren join McEwen Copper. With his more than 27 years of working in Argentina and experience in exploring the High Andes, we believe that his expertise and track record of success will play a key role in further enhancing Los Azules, which is already ranked as a top 10 copper project worldwide with significant growth potential."

Rob McEwen, Chairman and CEO of McEwen Mining, added “I look forward to the contributions Darren will make to McEwen Copper’s exploration endeavors as we pursue our ambitious goals.”
