Red River Resources says it has defined an extensive high-grade silver-indium system at its Orient project near Herberton.
The company recently collected 44 samples from Orient West and 37 samples from Orient East.
Sampling at Orient West returned an average grade of 357 g/t gold, 241 g/t indium, 8.2 per cent lead and 5.8 per cent zinc, with peak assays of 1730 g/t gold, 1,289 g/t indium, 39.1 per cent lead and 32.1 per cent zinc.
Sampling at Orient East returned an average grade of 240 g/t gold, 88 g/t indium, 5.9 per cent lead and 0.9 per cent zinc, with peak assays of 1365 g/t gold, 444 g/t indium, 25.8 per cent lead and 18.7 per cent zinc.
Red River has commenced drill targeting and aims to commence drilling after the wet season.
Red River has attracted a $190,000 Collaborative Exploration Initiative grant for work focused on indium in the Herberton region.
Indium has been named as a critical mineral, with applications including CIGS (copper-indium-gallium-selenide) thin film solar cells.
The company’s Isabel and Orient tenements host the highest-grade known indium deposits in Australia.
