Overview

Bramaderos is a world-class gold and copper discovery with multiple pathways to establishing a large 10M+oz AuEq mining centre in southern Ecuador

Stage 1: Establish Limon epithermal as a higher-grade gold-silver mine

Stage 2: Grow Brama-Alba and Melonal porphyries from surface

Stage 3: Convert porphyry targets at Playas, Porotillo, Limon

TARGETING +10MOZ GOLD EQUIVALENT

• 4,984 ha concessions at ~900m above sea level (asl)
• The project is supported by excellent infrastructure
  • Adjacent to the Pan American Highway
  • ~100km’s from Loja Airport
  • 93% of Ecuador’s power is generated from renewables
  • Potential for low-carbon footprint mining

Immediate priority is to establish an additional, high-grade, Mineral Resource Estimate for the Limon epithermal system.

The 4,959 Ha Bramaderos gold-copper porphyry project is located in Loja province, 130km (2-hour drive) from the provincial capital city Loja and west of Catacocha. The sealed Pan American Highway, which crosses the western part of the concession, provides easy access. The concession is approximately 900m’s above sea level.

The property is an incorporated joint venture between Sunstone Metals and Solgold, an LSE/TSX-V company.

The Bramaderos Project is held by La Plata Minerales (‘PLAMIN’), of which Sunstone Metals has 87.5% ownership and Solgold has 12.5%. Sunstone fully funds all activities at Bramaderos, and Solgold is loan-carried to production.

Various institutions and listed companies sporadically explored Bramaderos from 1970 to 1984, 2001 to 2002, and 2004 to 2007. This included stream sediment and soil sampling, followed by two phases of initial drilling programs.

The porphyry gold-copper mineralisation identified by historical and recent Sunstone-managed drilling campaigns at the Brama-Alba prospect, along with limited drilling in other prospects across the concession, suggests that Bramaderos has the potential to host significant gold and copper mineralisation.

The Limon gold-copper epithermal prospect and separate porphyry prospect, while still in an early stage, have the appropriate scale of surface alteration and gold plus copper grades from trenching, rock chipping, and a first phase of drilling to present an additional compelling epithermal-porphyry target with high tonnage potential.
