Results from the new definition drill program have further expanded the footprint of a large multi-phase hydrothermal system in the potential starter pit at Iska Iska with dimensions having increased to approximately 800m by 500m by 500m deep. The current results have increased dimensions by 100m by 100m along and across strike, compared with those previously reported.

TORONTO, Sept. 16, 2025 (GLOBE NEWSWIRE) -- Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) ("Eloro”, or the "Company”) is pleased to announce further assay results from five (5) drillholes (DSB-80, DSB-84, DSB-85, DSB-86 and DSB-87) of the second phase definition diamond drilling program. Four of these holes are located in the Polymetallic Domain (DSB-80, DSB-84, DSB-85 and DSB-86) and one is in the Tin Domain (DSB-87), in the potential Santa Barbara starter pit area. These results have further expanded the footprint of a large multi-phase hydrothermal system in the potential starter pit with dimensions having now increased to approximately 800m by 500m by 500m deep (see Figure 1). The current results have increased dimensions by 100m by 100m along and across strike, compared with those previously reported (see Eloro’s Press Release dated August 6, 2025). To date, a total of 6,242m of diamond drilling in twelve (12) holes has been completed in the current definition drilling phase. A total of 2,346m was completed in the five (5) holes reported, with assays pending for the remaining two holes totalling 1,025m.

Figure 1 shows the location of drill holes reported, Table 1 lists significant assay results and Table 2 lists drill hole coordinates.

Tom Larsen, Eloro’s CEO commented: "We are pleased with the steady progress of our drilling operations at Iska Iska, a crucial step toward advancing the project. The scale and potential of this system continue to impress us with long higher-grade intercepts, including 213.00m grading 0.51% tin and 25.46 g/t silver in both the Tin-Silver and Polymetallic Domains. These results underscore the importance of this phase of drilling in unlocking additional value for our shareholders. Notably, the Santa Barbara Zone remains open laterally and downdip, presenting significant opportunities for further infill and step-out drilling to expand and upgrade the mineral resources for the planned PEA.”

Dr. Osvaldo Arce, P.Geo., Executive Vice President Operations, Latin America for Eloro added: "The dynamic nature of hydrothermal events seen in the drill core at Iska Iska is very encouraging, particularly the vein-breccia and intrusion-breccia which are typical of high-grade porphyry-tin and polymetallic deposits of the Bolivian Tin Belt district. The hydrothermal system shows strong scale and complexity, and interpretation of drill core is vectoring us towards a system with potentially significant tin-polymetallic endowment. The current closer-spaced definition drill program has both upgraded and expanded the mineralization with significant higher-grade tin, silver and polymetallic zones which are still open laterally and at depth in the potential starter pit area at Santa Barbara zone. In addition, holes DSB-80, DSB-84 and DSB-85 intersected mineralization in areas that were previously modeled as waste within the resource model, due to lack of drilling. The mineralization encountered in DSB-86 (polymetallic) and DSB-87 (tin predominant) is very encouraging. Hole DSB-86 targeted the enriched epithermal mineralization in the eastern part of the system, and hole DSB-87 targeted a prominent intrusion breccia vein-breccia zone within the southwestern >0.30% tin zone. We are optimistic that additional drilling will further delineate the mineralized zone and potentially confirm larger extensions both laterally and at depth of both the tin and polymetallic system at Iska Iska."
