Zimbabwe is a major gold producer and the work described here was carried out to test the viability of gold characterisation studies in an area of ‘Granite-Greenstone’ - type gold deposits, where the geology and mineralisation are more complex than the other areas studied in Malaysia, Ecuador and Fiji.
"There are a lot of undeveloped refractory gold deposits that have less than 3 g/t gold head grade, and some are coupled with small resources which translates into short mine lives. Currently, those assets have little to no value as greenfield deposits and need a steep change in technology to unlock value," says Flanagan.
If you are looking to extract gold from refractory low-grade ores, we are introducing a game-changer to the entire gold mining industry. Your reserves containing refractory gold considered below the cut-off grade are not considered reserves because the cost of extracting it using pressure oxidation and bioleaching is too high.

The roasting plant was established in 1937 by the then government of Rhodesia to assist small and medium scale miners around Kwekwe in the processing of dumps or refractory gold ore. In refractory
