Thalanga survey targets copper-rich mineralisation
The program aims to increase production and/or extend mine life at Thalanga, which produces zinc, copper and lead
concentrates, with gold and silver credits.
Red River has commenced a microgravity survey, targeting polymetallic and copper-rich massive sulphide mineralisation at Thalanga Range and the Coronation prospects to define potential massive sulphide drill targets to be followed up later in 2021.
The company described a microgravity survey is a very high resolution gravity survey, with advantages including its non-invasive nature and effectiveness in targeting massive sulphide mineralisation.
To date, production from the Thalanga massive sulphide deposit (Thalanga, West 45 and Far West) has reached about 5.9Mt at 1.6 per cent copper, 2.5 per cent lead, 7.5 per cent zinc, 66 g/t silver and 0.5 g/t gold.
Red River said the Thalanga Range micro gravity survey had commenced and was targeting an area west of the Far West mine deposit.
It would then move north-west along the Thalanga Range up to the Flinders Highway and then westward along the range for 4km.
The Coronation survey is targeting copper-rich massive sulphide mineralisation in an area about 4km north-west of the historical Highway-Reward copper deposit.
The company said recent and historical exploration at the Coronation prospect had identified barite-quartz-sulphide-gold veins in conditions similar to the surface expression of the nearby Highway-Reward copper-rich massive sulphide deposit.
Red River holds an extensive portfolio of exploration tenements in the Mt Windsor volcanic belt in the Charters Towers region.
