Red River’s tenements in the Herberton region of North Queensland include two polymetallic projects hosting the highest-grade known silver-indium deposits in Australia and an exciting bulk tonnage silver target.
The Isabel and Orient Projects have potential to provide additional feed to Thalanga Operations or developed as standalone operations.
Red River’s Isabel Project includes the Isabel massive sulphide deposit and the Isabel Extended exploration target. The Isabel deposit has historic (non-JORC) mineral resource estimate of 85kt @ 15.3% Zn, 2.8% Pb, 0.7% Cu, 113 g/t Ag & 370 g/t In located within 100m of surface, with drilling and sampling required prior to further quantify the resource. Previous drilling at Isabel Extended target, 150m from the Isabel deposit, intersected massive sulphide mineralisation (7.25m @ 3.3% Cu).
The Orient Project includes the Orient West deposit and the Orient East bulk tonnage silver target.
Orient West has historical non-JORC Mineral Resource estimate of 229kt @ 5.1% Zn, 2.9% Pb, 180 g/t Ag & 190 g/t In, with drilling and sampling required prior to any further quantification of the resource.
Red River identified a large (450m by 200m) alteration zone associated with pervasive ferruginisation and fracturing at Orient East. The alteration zone is associated with a number of higher-grade silver-indium-lead-zinc vein systems. Historical drilling intersected high-grade silver-indium-lead-zinc mineralisation associated with wider zones of lower grade mineralisation over a potential 200m plus strike length.
Red River intersected extensive zones of epithermal silver-indium-lead-zinc mineralisation from a shallow depth in drillhole EO3. The mineralisation ended in a zone of lowgrade silver mineralisation and is open in all directions.
