Our Flagship High Grade Skarn System
Cerro Grande Skarn Corridor
Anchored by a High-Grade Copper-Gold-Silver Discovery
The Cerro Grande Skarn is located in the northern portion of the Adelita concession. The 300 metre high-grade discovery zone hosts 5 layers of Cu-Au-Ag skarn, remaining open in all directions.
Open in All Directions
Mineralization remains open laterally and at depth, with strong potential along a 6 km skarn corridor (Cerro Potrero and Cerro Potrero South)

Cerro Grande sits within a structurally active intrusive–carbonate corridor that is highly prospective for copper–gold–silver skarn mineralization.
Inaugural drilling supports a multi-horizon, vertically extensive skarn system, with new skarn horizons identified below historic drilling and mineralization remaining open along strike and at depth. This provides a strong foundation for continued step-out and deeper drilling as we systematically expand the footprint and advance toward resource delineation.

Upper Skarn Section 1
The uppermost mineralized skarn was intersected between (227.26m – 242.05m), returning 14.79 m averaging 1.4% Cu, 0.5 g/t Au and 20 g/t Ag.
This section is characterized by a magnetite-rich skarn with brown and green garnet assemblages, hosting disseminated and vein-controlled chalcopyrite, bornite and chalcocite.
The thickness and grade of this section are consistent with the upper skarn zones encountered in historical drilling, confirming down-dip continuity.

Our inaugural drill program has advanced Cerro Grande from a historical occurrence into a multi-horizon, stacked Cu-Au skarn system with porphyry affinity. The next phase is designed to aggressively expand the mineralized footprint and define the system architecture:
Vertical Extension: Systematic drilling above and below the newly identified horizons and follow-up on porphyry intersects.
Strike Extension: Step out drilling along the 6 km corridor, to demonstrate lateral continuity of newly identified system, advancing a district-scale structural framework.
Positioned as more than a single-zone discovery, Cerro Grande is being advanced as a scalable, multi-horizon copper-gold system: Built for systematic expansion along trend and at depth as we define the broader architecture and growth potential.
