Red River has been granted a number of tenements in the Herberton region of North Queensland. The tenements 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 be developed as stand-alone operations.
Herberton Silver-Indium Project Location
The Isabel Project includes the Isabel massive sulphide deposit and the Isabel Extended exploration target.
The Isabel deposit has historic mineral resource estimate of 85kt @ 15.3% Zn, 2.8% Pb, 0.7% Cu, 113 g/t Ag & 370 g/t In located within 100 metres of surface. (the historical estimate is not compliant with the 2012 JORC Code, drilling and sampling will be required prior to any further quantification of the resource).
Previous drilling at Isabel Extended target has intersected massive sulphide mineralisation (7.25m @ 3.3% Cu). Isabel Extend is location 150m from the Isabel deposit.
The Orient Project includes the Orient West deposit and the Orient East bulk tonnage silver target
Orient Project Sample Location Map
Orient West has historical mineral resource estimate of 229kt @ 5.1% Zn, 2.9% Pb, 180 g/t Ag & 190 g/t In (the historical estimate is not compliant with the 2012 JORC Code, drilling and sampling will be required prior to any further quantification of the resource).
Orient Silver Indium Project Sampling Summary
A large (450m by 200m) alteration zone associated with pervasive ferruginisation and fracturing, has been identified at Orient East. The alteration zone is associated with a number of higher-grade silver-indium-lead-zinc vein systems. Historical drilling has intersected high grade silver-indium-lead-zinc mineralisation associated with wider zones of lower grade mineralisation over a potential 200m plus strike length.
Drillhole EO3 Cross Section (Orient East Bulk Tonnage Target)
Drillhole EO3 intersected extensive zones of epithermal silver-indium-lead-zinc mineralisation from a shallow depth. The mineralisation intersected in EO3 has not been followed up (open in all directions) and EO3 was ended in a zone of low grade silver mineralisation.
