TARGET #3
Tres Amigos
Located in the southern corridor of the Salvadora Property, Tres Amigos is a standout target with confirmed high-grade copper-gold-silver mineralization, historical mining, and strong surface and subsurface indicators of a robust epithermal system.
KEY HIGHLIGHTS
-
Multiple epithermal vein systems traced at surface through mapping, sampling, and artisanal workings
-
Confirmed strike length of >2.5 km with consistent mineralized widths up to 200 m
-
Rock and soil sampling, limited IP, and shallow drill programs have confirmed significant copper and gold values
-
Legacy workings from the La Fortuna Mine (active as recently as 2006) extracted high-grade oxide ore grading up to 14% Cu
-
San Lorenzo face sampling at the adit confirmed 14.75% Cu over 4.1 m
-
Surface alteration and mineralization suggest potential for depth and lateral extensions
INVESTOR TAKEAWAY
Tres Amigos presents a well-defined, underexplored system with established high-grade mineralization and evidence of historical production. Follow-up drilling will aim to define scale, continuity, and potential resource volumes across the remaining strike extent.
TARGET LOCATION
Epithermal Cu-Au-Ag Target in a Proven Structural Corridor
Positioned in the north-central Salvadora Property, Tres Amigos features a large-scale epithermal copper-gold-silver system with extensive surface expression and historical artisanal mining. Its NW-SE structural setting and early exploration success make it an immediate follow-up priority.
EXPLORATION NOTES
-
NW-SE corridor with hydrothermal alteration and vein-hosted mineralization.
-
Surface sampling and workings confirm high-grade Cu-Au mineralization.
-
Multiple subparallel epithermal veins mapped across a broad footprint.
-
Historical access via decline supports near-term development.
-
Located in Chile’s Mega Porphyry Belt, near key infrastructure.
INVESTOR TAEAWAY
Tres Amigos combines scale, grade, and accessibility — with surface showings and confirmed mineralization over 2.5 km. Its position within a proven copper-gold belt and strong early results set the stage for value creation through additional drilling and geophysical work.
TRES AMIGOS PAST DRILLING HIGHLIGHTS (2016 & 2018)
Demonstrating Scale, Continuity & High-Grade Copper Mineralization
Two phases of drilling (2016 & 2018) confirmed a copper-gold-silver enriched epithermal vein system at Tres Amigos. These initial results established the core of the mineralized zone and validated the potential for expansion along strike and at depth.
KEY HIGHLIGHTS

-
including 8 m @ 1.58% Cu and 0.47 g/t Au

SURFACE SAMPLING & PRIOR DRILLING
Validating a High-Grade,
Near-Surface Copper-Gold System
SURFACE SAMPLING (DEC 2023)
A chip and soil sampling campaign confirmed broad mineralization and guided future targeting.
KEY HIGHLIGHTS
-
Two anomalous soil zones (1–1.5 sq km) averaged 0.2–0.28% Cu
-
Rock chip samples returned 0.3%–5.6% Cu and up to 2.88 g/t Au
-
La Fortuna zone returned high-grade intercepts from prior drilling
-
Sin Codicia area remains underexplored, with geophysics and drilling planned
HISTORIC PRODUCTION
-
Artisanal mining occurred at La Fortuna and Sin Codicia, including underground access and surface cuts
-
In 2006, high-grade oxide ore (up to 14% Cu) was extracted from La Fortuna’s spiral decline
-
San Lorenzo face sampling confirmed grades of 2.5–14.75% Cu across 1.8–4.1 m widths
GEOPHYSICS & UPCOMING IP PROGRAM
Expanding IP Coverage to Define High-Priority Drill Targets
San Lorenzo will expand geophysical coverage to the north and northwest, targeting areas near the Sin Codicia Mine where high-grade Cu-Au samples have been collected.
EXPLORATION NOTES
-
Additional IP lines aim to identify chargeability anomalies linked to subsurface mineralization.
-
Results will inform drill targeting across the broader Tres Amigos zone.
-
Follow-up drilling to begin once data is received and interpreted.
HISTORICAL MINING & SURFACE WORKINGS
A Well-Mineralized Corridor with a Legacy of Artisanal Activity
Extensive artisanal mining along the Tres Amigos and Arco de Oro trends underscores the scale and continuity of mineralization across Salvadora’s two primary NW-SE corridors.
EXPLORATION NOTES
-
Workings are spatially aligned with hydrothermal corridors and coincide with key structural features
-
Field observations suggest multiple vein-hosted epithermal systems enriched in copper and gold
INVESTOR NOTES
-
High-grade soil and rock samples—combined with widespread artisanal mining—confirm the presence of multiple hydrothermal systems across the property
-
The density and extent of these workings validate management’s view that Salvadora is host to large-scale mineralized systems warranting aggressive follow-up
SUMMARY & NEXT STEPS
High-Priority Copper-Gold Target Poised for Growth
San Lorenzo’s exploration at Tres Amigos has confirmed a robust, near-surface epithermal copper-gold-silver system with broad surface expression, historical high-grade production, and strong geophysical and geochemical support. This target remains largely underexplored and holds substantial discovery upside.
INVESTOR OUTLOOK
With confirmed high-grade mineralization, large-scale surface anomalies, and favorable infrastructure access, Tres Amigos is positioned as a near-term catalyst within the Salvadora Property. San Lorenzo is advancing this target with the aim of defining a large-scale, multi-metal resource through data-driven exploration.
NEXT STEPS
-
Expand IP coverage to define full strike extent and depth potential
-
Refine drill targeting based on geophysical and geochemical integration
-
Initiate systematic drill testing of priority zones across the 2.5 km corridor
-
Evaluate broader mineralized footprint through continued mapping and sampling
