Gunnison Copper Signs Letter of Intent with Defense and Mineral Exploration Tech Start-Up Lunasonde to Assess Its Revolutionary Technology to Explore for Copper, Other Critical Minerals, and Rare Earth Elements in Arizona's Cochise Mining District
Evaluating Airborne Georadiotomography (aGRT) for Potential Copper and Rare Earth Targeting
Phoenix, Arizona--(Newsfile Corp. - September 23, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to announce that it has entered into a non-binding Letter of Intent ("LOI") with Lunasonde Inc. ("Lunasonde"), a U.S.-based defense technology start-up specializing in airborne based subsurface imaging.
Under the LOI, Gunnison will provide access to its district-scale land package in southeastern Arizona, allowing Lunasonde to test and refine its advanced experimental remote sensing technology. The goal is to accelerate the identification of new copper, other critical minerals, and rare earth element targets within the Company's Cochise Mining District assets.
"Geology like that of the Cochise Mining District has been known to host at least 12 of the Critical Minerals so important to the US supply chain, yet most of this geology lies, un-explored, beneath thick alluvial cover. We are delighted to explore this partnership with Lunasonde who's technology has the potential to see through this cover and make new discoveries," stated Stephen Twyerould, President & Chief Executive Officer.
"Our partnership presents an unparalleled opportunity to demonstrate how Lunasonde can accelerate critical mineral exploration," says Jeremiah Pate, Lunasonde's Founder and Chief Technology Officer.
The parties intend to apply for funding of this venture under the United States Department of Energy ("DOE") ROCKS (Reliable Ore Characterization with Keystone Sensing) Program. The transaction remains subject to the negotiation and execution of definitive agreements, successful submission and approval of the DOE funding application, and customary closing conditions.
