Riqueza Marina Copper & Gold Host Project
Cretaceous meta-volcanic and sedimentary VMS rocks, including mafic pillow basalts, andesites, rhyolite tuffs/flows/domes, and extensive silica exhalites
Analogous to large VMS deposits in Latin America, including Tambo Grande, San Nicholas, and Campo Morado.
Three mineral leases totaling
12,041 hectares
Targets Drill Ready
Five high potential target areas have been identified on the basis of geology, geochemistry, and geophysics
Riqueza Marina Target Areas
- Extensive outcrops and subcrops of high-grade mineralized (Cu-Au-Pb-Zn) gossan occur along a 3km strike length at priority targets ‘Laminas West’ and ‘Laminas East’
- Multiple areas of high-grade (>0.5% Cu) surface mineralization
- Large Gravity Anomalies may represent buried massive sulfide horizons
- Substantial gravity high adjacent to a mineralized ‘Rhyolite Dome’
- 'Southern Area’ additional geological mapping and work to commence in 2022
- ‘Northern Area’ recently discovered
Comparison Of Riqueza Marina And San Nicholas Gravity Anomalies At Same Scale
High grade, open pit operation with 3-4 year timeline to production • Low first quartile costs, offering quick payback • 2016 drill program and scoping study improved understanding and augmented value
Mineral Resources at San Nicolás are 102.5Mt @ 1.24% Cu, 1.63% Zn, 25. 7g/tAg and 0.44g/t Au consisting of 91.7Mt @ 1.24% Cu, 1.70% Zn, 26.7 g/t Ag and 0.46g/t Au in the Indicated category and 10.8Mt @ 1.24% Cu, 1.00% Zn, 17.4g/t Ag and 0.26 g/t Au in the Inferred category
