GELUM COMPLETES ACQUISITION OF LAS TINAJAS GOLD PROJECT, NORTHERN MARICUNGA BELT, CHILE

Gelum Resources Ltd., further to its news release dated Feb. 27, 2026, has signed an option agreement with Sociedad Contractual Minera Las Tinajas and Compania de Inversiones Mineras S.A., both of Santiago, Chile, and both at arm's length to the company, whereby Gelum may earn a 100-per-cent interest in the Las Tinajas gold project, covering 2,600 hectares in the north end of the Maricunga gold belt, Chile. Las Tinajas is located 120 kilometres (km) northeast of Copiapo, in the Atacama region of northern Chile. Gelum has completed due diligence over the last 60 days to their satisfaction.

Henk van Alphen, chief executive officer, states: "It is a very unique opportunity to find a project like Las Tinajas, which is located in one of the most prolific gold regions of the world where there are broad intervals of 30 to 80 metres of gold mineralization. This by itself would be very impressive, was it not for the fact that many drill holes ended in mineralization. This points to a system with bulk-tonnage open-pit potential."

Las Tinajas is located 120 km northeast of Copiapo, in the Atacama region of northern Chile, at the north end of the Maricunga gold belt. The Maricunga belt is the largest gold belt in Chile, extending for 200 km with both porphyry and high-sulphidation types with a total of 103 million ounces. The 2,600-hectare claim block lies between 3,600 and 4,000 metres above sea level and is accessed via a Codelco-maintained mining road.

Highlights:

• Gelum Resources is targeting a large epithermal disseminated gold deposit located at the north end of the Maricunga belt in northern Chile: a renowned gold-copper porphyry district;
• Gold mineralization is associated with silicified porphyry intrusions and associated diatreme breccias;
• Since 1986, 64 drill holes totalling 10,990 m have been drilled in three campaigns, the most recent being 16 holes totalling 2,831 m drilled in 2024 to 2025;
• Multiple historical holes have significant intervals of more than one gram per tonne (g/t) gold, with several ending in more than one g/t gold;
• Only a small portion of the claim block has been drilled. There is significant potential to expand the known mineralized centres associated with the diatreme breccia.
