Project Overview
The Cobrasco Project in Colombia’s Chocó Copper Belt is a significant new copper-molybdenum porphyry discovery by Rugby Resources. The first drill hole returned up to 808m at 0.42% Cu with high-grade bornite mineralization. The project covers a 3 km² geochemical anomaly and remains open in all directions.
Situated within a major Andean porphyry gap – between some of South America’s largest copper districts – Cobrasco stands out as one of the few untested, district-scale porphyry systems in the region.
With logistics, permits, and community support already in place, Cobrasco is fully drill-ready and holds strong potential for expansion.

Drilling to date
Outstanding drill intercepts from first three holes: porphyry Cu–Mo mineralization commencing near surface and extending to depth.
CDH001:
- 808 m @ 0.42% Cu, 79 ppm Mo (from 184 m to 992 m).
- Including 138 m @ 0.77% Cu, 164 ppm Mo.
- High-grade: 82 m @ 0.90% Cu, 199 ppm Mo.
CDH002:
- 70 m @ 0.29% Cu, 50 ppm Mo (near surface).
- 754 m @ 0.46% Cu, 76 ppm Mo (from 152 m to 906 m).
- High-grade: 172 m @ 0.74% Cu, 78 ppm Mo.
CDH003 (drilling paused at 300.6 m):
- 60 m @ 0.27% Cu, 57 ppm Mo (from 8 m to 80 m).
- 144.6 m @ 0.69% Cu, 155 ppm Mo (from 156 m to 300.6 m).
- High-grade: 100.6 m @ 0.72% Cu, 210 ppm Mo.
Early Days of a Major New Porphyry Copper District
- 808 m @ 0.42% Cu, 79 ppm Mo (from 184 m to 992 m).
- Including 138 m @ 0.77% Cu, 164 ppm Mo.
- High-grade: 82 m @ 0.90% Cu, 199 ppm Mo.
- Pathfinder geochemistry indicates the presence of multiple porphyry centres along and beyond key geological contacts.
- Potential for preserved, unexposed (“blind”) porphyry systems.
Geophysics
Fist 3 holes intersected wide intervals of strong Cu-Mo mineralization.
LARGE PORPHYRY COPPER TARGET CONFIRMED.
Strong correlation with geophysics.
Open in all direction and depth.
Magnetic modelling indicates porphyry body extends to >1500m depth
Significant Upside
Geological significance:
- Large, underexplored segment of the Andean porphyry belt.
- Bornite-dominant mineralisation indicates potential for a higher-grade core.
- Multi-phase intrusive system with potassic alteration.
Exploration upside:
- Multiple untested porphyry centres remain open for discovery.
- 3 km² Cu–Mo soil anomaly aligns with drill intercepts.
- System remains open laterally and at depth (drilling paused at only 300 m in CDH003).
Drill-ready status:
- Community agreements, camp, and infrastructure are in place.
- Permits secured, program poised to restart—expected to resume in 2026.
