San Lorenzo Gold Completes Expanded Geophysical Survey at Salvadora Gold-Copper Project in Chile

Calgary, Alberta — June 17, 2025 — NewsWall — San Lorenzo Gold Corp. (TSXV: SLG) has completed an expanded induced polarization (“IP”) geophysical surveying program at its Salvadora gold-copper project in Chile.

The IP program included infill and extended coverage over the Cerro Blanco porphyry target, and expanded coverage in a northwest direction on the Arco de Oro epithermal target. Preliminary IP sections have been received, and the company intends to finalize drill targets and mobilize a drill rig for the next phase of drilling at Salvadora in the near term.

San Lorenzo has also redesigned and updated its website and its Corporate Presentation, which can be viewed at www.sanlorenzogold.ca. Website improvements are ongoing.

San Lorenzo is focused on advancing its flagship Salvadora property located in Chile’s mega-porphyry belt. Prior drilling programs have indicated the presence of significant gold and copper enriched epithermal and porphyry style systems within the Salvadora property.
