Cobrasco Copper-Molybdenum Project

Chocó, Colombia

Aegis holds a 20% interest in the project, free-carried through to completion of a feasibility study. The project is now being advanced by Andina.

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.

Geochemistry

CDH01
CDH03

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.

Early Days of a New Porphyry Copper District

  • Initial discovery at Cobrasco North open in all directions. 
  • Adjacent to the Comita porphyry copper discovery. 
  • Only 3 drill holes completed on a +3km2 anomaly 
  • Pathfinder geochemistry indicates the presence of multiple porphyry centres along and beyond key geological contacts.
  • Potential for preserved, unexposed (“blind”) porphyry systems.
