San Lorenzo Gold Corp. (TSXV: SLG; OTC: SNLGF) has released an exploration update from its 11,962-hectare Salvadora Project in Chile's Atacama Region, identifying a new approximately 2-kilometre gold-bearing structural corridor at Quebrada Salada and expanding the geophysical footprint at its San Juan discovery. Reconnaissance sampling at Quebrada Salada returned gold values up to 12.80 g/t Au across multiple locations along the mapped trend. Separately, the company confirmed its permitted drill program at Cerro Blanco is now underway, adding further momentum to an already active exploration season.

Key Points

  • San Lorenzo Gold Corp. (TSXV: SLG; OTC: SNLGF) released an exploration update on September 17, 2026
  • Quebrada Salada mapping outlines an approximately 2 km north- to northwest-trending structural corridor with gold values up to 12.80 g/t Au
  • San Juan IP lines D10 and D11 expand the geophysical footprint beyond existing discovery drilling; prior intercepts include 102.3 metres grading 1.33 g/t Au
  • Investors may be watching for results from the Cerro Blanco drill program and step-out drilling planned toward the D9 chargeability response at San Juan

Quebrada Salada Emerges as a New Epithermal-Style Exploration Target

Reconnaissance prospecting and geological mapping at Quebrada Salada outlined an approximately two-kilometre-long, north- to northwest-trending structural corridor containing multiple subparallel felsic dykes and iron oxide-quartz vein zones. A total of 27 rock and regolith samples were collected in June 2026 and submitted to independent laboratory Andes Analytical Assay SpA in Copiapó, Chile. Gold values reached up to 12.80 g/t Au, with anomalous gold identified at multiple points along the mapped trend. The company notes the gold-bearing structures occur along the eastern margin of existing IP coverage, where several chargeability responses are present, while portions of the trend remain outside the current geophysical footprint.

San Juan Discovery Area Grows as New IP Lines Expand Chargeability Picture

San Lorenzo has incorporated newly completed IP lines D10 and D11 into its interpretation of the San Juan discovery area, building on prior D8 and D9 surveys. San Juan was originally discovered by drilling a blind chargeability anomaly on line D8, which subsequently returned intercepts including 102.3 metres grading 1.33 g/t Au and 52.6 metres grading 1.67 g/t Au in hole SAL-10-25, and 58.5 metres grading 1.07 g/t Au and 60.3 metres grading 1.01 g/t Au in SAL-09-25. The expanded D8-through-D11 dataset reveals sizeable chargeability responses across the wider area, and the company states that the geophysical footprint at San Juan now extends substantially beyond ground tested by drilling to date.

Cerro Blanco Drilling Advances Alongside Integrated 3D Geophysical Compilation

The permitted 20-pad drill program at Cerro Blanco is underway, designed to follow up previously reported broad gold mineralisation zones and test the scale and continuity of the system. Previous drilling at Cerro Blanco included 153.5 metres grading 1.04 g/t Au in hole SAL-01-24. In parallel, San Lorenzo is progressing an integrated 3D compilation covering approximately a decade of geophysical work spanning roughly 18 km of the Salvadora property, aimed at improving property-scale geophysical understanding and supporting new target generation and drill planning.
