San Lorenzo Reports Final Assay Results from Hole SAL 10-25 with Drilling Ending in Porphyry Style Mineralization at the Arco de Oro Target

By The Northwire Desk — AI Analysis Jun 04, 2026 · 08:00 SLG · 5.36 San Lorenzo Gold Corp.
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.
