THE SALVADORA OPPORTUNITY
A Scalable, Underexplored Asset in a Tier-1 Mining District
Spanning 8,963 ha, Salvadora hosts multiple mineralized zones confirmed by historic mining, artisanal workings, and modern exploration — all pointing to a scalable, high-grade discovery opportunity.
INVESTMENT OPPORTUNITY
-
Proven copper-gold systems with high-grade intercepts and strong geophysical correlation across multiple high-priority targets
-
Historical and artisanal workings validate surface expression and continuity
-
Underexplored despite proximity to one of Chile’s largest porphyry deposits
-
Clear forward path: geophysics expansion, focused drilling, and resource definition
Investor Notes: land package is underexplored yet shares geological traits with some of the largest porphyry systems in the world.
GEOLOGICAL SETTING
Outer Rims of Caldera Collapse Zones
San Lorenzo’s Salvadora Property and Codelco’s El Salvador Mine are both situated along the outer rims of large caldera collapse zones — a proven geological setting for major porphyry and epithermal mineralization. These zones have undergone intrusive uplifting and mineralized fluid migration, with fluids migrating through fractured cap rocks and along fault systems generated by tectonic and magmatic activity.
This setting is consistent with large-scale, multi-phase mineralizing events — reinforcing Salvadora’s potential to host significant copper and gold deposits.
IP & GEOPHYSCAL COMPILATION
Uncovering Anomalies Across a Large Underexplored System
The image (right) is a compilation map of geological, geochemical, and IP chargeability anomalies across the Salvadora property, illustrating the scale and mineralization footprint of the property.
EXPLORATION NOTES
-
Multiple chargeability anomalies have been defined to date, many of which correlate with known surface mineralization and drill intercepts.
-
Drilling and geophysical data collectively support the presence of several large-scale hydrothermal systems across the property.
-
The combination of porphyry and epithermal features is consistent with a multi-phase mineralizing environment.
HISTORICAL MINING
A Legacy of
High-Grade Extraction
The historical footprint of artisanal mining across the Salvadora Property provides strong evidence of sustained, high-grade mineralization. These past activities reflect the widespread presence of mineralized systems and reinforce the exploration model currently being advanced by San Lorenzo.
EXPLORATION NOTES
-
Large clusters of historical workings follow defined mineralized trends.
-
High-grade gold, silver, and copper assays from surface sampling and drilling confirm the potential for commercial-grade deposits.
-
These results validate San Lorenzo’s systematic, phased exploration strategy.
HISTORICAL MINES
-
Mina Alaska (southern Arco de Oro trend):
-
Over 85,000 tonnes of high-grade ore historically extracted
-
Reported gold grades ranged from 4.5 to 66 g/t from surface down to 280 m
-
-
These results support the potential for commercial-scale deposits and validate the systematic exploration approach.
Next Steps
-
Expand geophysical coverage to define scale and depth across NW corridors
-
Execute ongoing drill campaigns at Cerro Blanco, Arco de Oro, and Tres Amigos
-
Integrate geochemistry, IP, and structural mapping to refine resource targets
-
Advance project toward resource delineation through phased, data-driven exploration
