El Domo, located within the Curipamba project, Bolivar and Los Rios Provinces, Ecuador is hosted in a juvenile volcanic-magmatic arc of the Paleocene-Eocene Macuchi Terrane that is known to host at least two other volcanogenic massive sulphide deposits.
Sulphide mineralization at El Domo is principally located at the contact between a felsic volcanic dome and overlying volcaniclastic strata and is generally flat lying. It has been traced for approximately 800m in a north-south direction and between 350m and 500m east-west.
A Mineral Resource estimate for El Domo has been completed as part of the PEA to include all infill drilling completed in 2018. The updated, open pit constrained, Mineral Resource estimate for El Domo has an effective date of 2 May 2019 and is supported on information provided from 309 core boreholes, totalling 60,449 metres, completed between 2007 and 2018. The new Mineral Resource estimate has a total tonnage distribution of approximately 14%, 73%, and 13% classified in the Measured, Indicated and Inferred categories, respectively.
Measured Mineral Resources for El Domo total 1.4 million tonnes grading 1.92% copper, 0.37% lead, 3.52% zinc, 3.75 g/t gold and 58 g/t silver. The Indicated Mineral Resources for El Domo total 7.5 million tonnes grading 2.02% copper, 0.26% lead, 2.81% zinc, 2.33g/t gold and 49 g/t silver. The Inferred Mineral Resources for El Domo total 1.3 million tonnes grading 1.52% copper, 0.20% lead, 2.25% zinc, 1.83 g/t gold and 42 g/t silver.
