Gelum Targets Additional Mineralization Beyond Known Existing Gold Targets

Vancouver, British Columbia--(Newsfile Corp. - July 7, 2026) - Gelum Resources Ltd. (CSE: GMR) (OTCQB: GMRCF) ("Gelum" or the "Company") reports it has completed a second comprehensive rock sampling programme on its Las Tinajas Gold Project ("Las Tinajas" or the "Project"), covering 2,600 hectares in the north end of the Maricunga Gold Belt, Chile (see press release of April 30, 2026, May 19, 2026, and June 23, 2026). The 403 rock samples are expected to extend the well-documented gold mineralization that was identified by historical drilling and recent surface rock sampling by Gelum, and determine the potential for related porphyry-copper mineralization near the southern and western limits of the Project.

The entirety of the Project is surrounded by a land package under development by a Joint-Venture between Rio Tinto and CODELCO (the "Nuevo Cobre Project", Map 1), which targets porphyry copper mineralization below epithermal gold deposits in the district. Several porphyry copper deposits lie within 10km of Las Tinajas in the Potrerillos Cu-Au District.

As announced on June 23, 2026, Company contractor Southern Rock Geophysics has mobilized to complete magnetotellurics (MT) and vector induced polarization (VIP) surveying at Las Tinajas. The primary objective of the survey is to characterize the distribution of resistivity across the entire the project area, from near-surface levels down to depths of nominally 3,000 metres or greater for the MT survey, and to approximately 800 metres for the VIP chargeability and resistivity parameters. Southern Rock Geophysics work is to establish specific porphyry drill targets on the back of historical data collected and analysed to date. Management intends to use the funds from the recent equity raise to immediately drill once targets are established (see press release June 23, 2026).

Hendrik van Alphen, CEO of Gelum Resources, stated, "The Las Tinajas Gold Project is a fantastic land package. We know we have significant gold mineralization already, as evidenced by past work, but the general neighborhood around the Project is ripe with other geological features, including copper mineralization. The respective leaders of the Joint-Venture between Rio Tinto and CODELCO have said on the record that the region promises to be an entire "mining district" and Gelum is fortunate enough to be right in the middle."
