Gelum's Geophysical Survey Resumes at the Las Tinajas Project, Chile

(CSE:GMR, OTCQB:GMRCF) Gelum Resources Ltd. announced that the geophysical survey at its Las Tinajas Gold Project, covering 2,600 hectares in the north end of the Maricunga Gold Belt, Chile, resumed on October 20, 2026. The survey originally commenced in July 2026 but was paused when crews demobilized due to significant snowfalls in August and September. The survey is expected to be completed in about three weeks from the resumption date. The Las Tinajas Gold Project is surrounded by a land package under development by a Joint-Venture between Rio Tinto and CODELCO, known as the Nuevo Cobre Project, which targets porphyry copper mineralization below epithermal gold deposits. Several porphyry copper deposits are located within 10km of Las Tinajas in the Potrerillos Cu-Au District. Southern Rock Geophysics, the company’s contractor, has mobilized to complete magnetotellurics (MT) and vector induced polarization (VIP) surveying at Las Tinajas. The MT survey aims to characterize resistivity down to depths of nominally 3,000 metres or greater, while the VIP survey will cover resistivity and chargeability parameters to approximately 800 metres. The primary objective of the survey is to establish specific porphyry drill targets based on historical data collected and analyzed to date. Management intends to use funds from a recent equity raise to immediately drill once targets are established. Hendrik van Alphen, CEO of Gelum Resources, commented that the Las Tinajas Gold Project is a significant land package with known gold mineralization and is located in a region with additional geological features, including copper mineralization. The leaders of the Rio Tinto and CODELCO Joint-Venture have stated that the region promises to become an entire mining district, with Gelum positioned centrally. John Drobe, P.Geo., a qualified person as defined by NI 43-101, has reviewed and approved the technical disclosure in this news release. Mr. Drobe is a consultant for the company and holds stock options.
