San Lorenzo drills epithermal targets at Arco de Oro

  CALGARY – TheNewswire - June 29, 2026 -  San Lorenzo Gold Corp. (" San Lorenzo " or the " Corporation ") (TSXV: SLG and OTC: SNLGF) is pleased to announce that it has significantly expanded the mineralized footprint and confirmed key strike extensions on the Salvadora property. Highlights : Assay results from four holes have been received which were drilled on the “San Juan Extension” – a northwest extension to the Arco de Oro “Core Zone”.    The four holes were designed to test the epithermal vein system previously intersected by San Lorenzo in the Arco Core Zone located approximately 3.5 kilometers (“km”) to the southeast.    Specifically, the four holes tested the system between 3.4 km and 3.9 km northwest of the nearest hole previously drilled on the Arco de Oro epithermal trend.  These results significantly expand the known footprint of the epithermal system at Arco de Oro.  The four holes were designed to test shallow epithermal mineralization and not large porphyry targets (as drilled by holes SAL-10-25 and SAL-09-25 - see SLG release dated June 4, 2026).    Step-outs from holes SAL-10-25 and SAL-09-25 - to test continuity of the porphyry system - are included in the upcoming drilling program due to commence within approximately 7 days.    The potential for significant porphyry mineralization at San Juan exists requiring further testing.  All four drill holes intersected the epithermal vein system that extends to surface, together with mineralized surrounding rock, generating the following results: SAL-11-25 :  18.9m at 1.06g/t Au from 48.3m, including 1.6m at 5.68g/t Au   SAL-12-25 :  21.5m at 1.32g/t Au from 68.5m, including 3
