Between 1901 and 1916 gold ore from Mount Grainger Goldfield, 10 km north of Oodla Wirra, was treated by battery amalgamation and cyanidation at the Mount Grainger Mine. Tailings and slimes from this ore processing period still remain on site, and were investigated to determine if they could be profitably reworked in the present climate of high gold price and access to more refined gold extraction techniques. On Mining Lease 4830 an indicated 1900 tonnes of tailings, previously incompletely cyanided, containing 0.87 g/t gold, plus 370 tonnes of untreated, ex-battery slimes containing 3.54 g/t gold are seen as suitable for modern cyanidation. Processing tests performed on samples taken from the spoil areas show that economic, gold extraction yields of 46% (760 g) and 90% (1180 g) respectively for tailings and slimes may be obtainable.
