Gravitational concentration, flotation of gold oxides and sulphides and agitation leach of copper oxides

Metallurgical tests show good recoveries

High grades imply that low Capex is required to achieve desired production

2nd stage in development, first drilling at India Coya confirms that ore shoots continue at depth

Projects located in mining friendly district, no relevant environmental/community stakeholders

identified

Estimation of 2 years to start production

Access to mineral resources completed at India Coya trough mining ramp

Underground operation by Bench & Fill method at competitive cash cost

High grade, low Capex & Opex project in mining friendly district

India Coya Project

High grade Cu/Au oxide vein, located 25km south from Copiap. Ore shoots 3-5m wide.

1st exploration stage completed: 680m of access tunnels and 4,900m drilled from the tunnel towards the vein. 2 major high grade ore shoots identified

93koz @ 7.4 gpt Au Eq M,I&I Resources (non NI 43-101), including 63koz @ 7.7gpt Au Eq M+I, determined in oxide zone. Structure remains open at depth and along strike.

2nd exploration stage underway, preliminary results of first 3 drills show:

Central shoot resources extend al least 350m below surface

South shoot increases width and grades at depth
