Executive Summary

San Lorenzo Gold Corp. released the final assay results for drill hole SAL 10-25 at the Arco de Oro target, confirming continuous gold mineralization down to 574 meters.
The hole intersected significant intervals including 52.6 m at 1.67 g/t Au, 48.0 m at 0.91 g/t Au, and 65.0 m at 0.81 g/t Au, with mineralization remaining open at depth.
Geological analysis indicates a large, deep porphyry-style copper-gold system with potassic alteration strengthening with depth and multi-directional pyrite-chalcopyrite rich veins.
The company plans immediate follow-up drilling to delineate the intrusive complex and test IP line D8 anomalies, which could extend the system's strike length beyond 6 km.
Permitting for Phase 7 drilling at the Salvadora property has been submitted, with pad construction and rig mobilization expected imminently.
Six additional holes from the current program await assay results, though turnaround times remain slow due to high Andes drilling demand.

Material Impact

The release confirms the company's hypothesis of a large-scale gold-rich porphyry copper-gold system at Arco de Oro, validating the strategic direction of the exploration program.
While the results are positive and align with the partial results released on May 8, 2026, they are incremental follow-up data rather than a completely new discovery.
The confirmation of a potential 6 km strike length significantly de-risks the Arco de Oro target and enhances the long-term resource potential of the Salvadora property.
The news is classified as Routine - Positive because it represents the expected completion of a previously announced drill hole and follows directly on the heels of the May 8 announcement that already priced in the porphyry system potential.
The imminent start of Phase 7 drilling provides a clear near-term catalyst, but the market has already reacted to the broader exploration success, as evidenced by the stock's run from $0.20 to nearly $6.00 over the past year.
