King Copper Discovery Appoints David Burrows to Technical Advisory Team

VANCOUVER, British Columbia, Sept. 28, 2026 (GLOBE NEWSWIRE) -- King Copper Discovery Corp. (“King Copper” or the “Company”) (TSX-V: KCP, OTCQB: TBXXF, FSE: 3RIO) is pleased to announce that Dr. David Burrows has joined the Company’s Technical Advisory Team following his review of historical drill core, geological data and the broader exploration opportunity at the Colquemayo Copper Project in southern Peru.

Dr. Burrows brings more than 30 years of global exploration experience, including as Chief Geologist, Global Exploration at Vale for 16 years (2006-2022) and before that at Inco Exploration (1990-2006). His career has included extensive exploration experience across porphyry Cu-Au-(Mo) and high-sulphidation epithermal systems in Indonesia, the Philippines, Peru and Chile.

Importantly, Dr. Burrows was a member of the discovery team responsible for the Onto Cu-Au discovery in Indonesia, which received the 2025 PDAC Thayer Lindsley Award for an international mineral discovery. He is also co-author of “The Onto Cu-Au Discovery, Eastern Sumbawa, Indonesia: A Large, Middle Pleistocene Lithocap-Hosted High-Sulfidation Covellite-Pyrite Porphyry Deposit.”

His experience evaluating large-scale porphyry and high-sulphidation systems complements King Copper’s ongoing technical work at Colquemayo, where the Company has identified five priority porphyry targets beneath and adjacent to an extensive high-sulphidation lithocap and historically drilled copper mineralization.

Dr. Burrows holds a Ph.D. and M.Sc. in Economic Geology from the University of Toronto and a B.A. in Natural Sciences (Geology) from Trinity College Dublin. He is also an Adjunct Professor of Geology at Laurentian University.

Dr. Burrows joins a technical team that includes Doug Kirwin, Lead Strategic and Technical Advisor, and Chico Azevedo, Vice President of Exploration.

Jonathan Richards, Chief Executive Officer, commented: “We are very pleased to welcome David to King Copper Discovery’s Technical Advisory Team. His extensive experience with porphyry and high-sulphidation systems, including his involvement in the award winning Onto Cu-Au discovery, is highly relevant to the geological setting we are evaluating at the Colquemayo Copper Project. David has had the opportunity to review our historical drill core and technical data, and his perspective will be valuable as we continue to refine our geological model and advance our priority targets toward drilling. With David joining Doug Kirwin and Chico Azevedo, we have assembled an exceptional depth of global discovery and exploration experience around Colquemayo.”

The appointment follows a period of significant technical and corporate advancement at Colquemayo, including the recent expansion of King Copper’s land position across the broader Colquemayo copper district.
