Santa Rosa Gold Project

The 100% owned 10,000 hectare Santa Rosa Gold Project is an intrusive hosted structurally-controlled quartz stockwork system located within the prolific Antioquia Batholith near the town of Santa Rosa de Osos and lies 70 kilometres to the north of Medellin. Gold mining within the Santa Rosa Gold Project area pre-dates the 17th century when an estimated 30 million tonnes were mined.

San Ramon Gold Mine

The San Ramon Gold Mine (a single shear zone within the Santa Rosa Gold Project) trends east-west, dips 70o to the north, extends over 2 kilometres, is up to 50 metres in width and is mineralized from surface.

  • Cash Cost US$596. All-In Sustaining Cost US$647
  • Post-tax project economics IRR 53% and payback within 1.3 years (at $1,300 Au)  
  • Process - SAG mill (P80 125 micron), floatation and CIL circuit
  • Straightforward metallurgy with 96% recoveries – Au/Ag dore
  • Mining method - Shrinkage stoping with delayed fill
  • Dry stacked tailings - 60% used as backfill
  • Opportunity to ramp up 2000 tpd with near mine, drill ready regional exploration targets (~2km)
  • Excellent infrastructure (water, roads, grid power, local staffing)

Exploration Potential

The San Ramon Gold Mine deposit is open at strike to the east and also at depth, as reserves have only been delineated to 250m in depth. Deep drill holes (~600m) confirm mineralization, but currently Red Eagle Mining lack the drill density at depth for resource estimation. The San Ramon Gold Mine deposit appears to plunge eastward onto ground recently acquired from AngloGold Ashanti. Exploration success on strike and at depth will increase the mine life at the San Ramon Gold Mine.
