economic cut-off gold grade for refractory ores is somewhat higher than non-refractory ores. The mining industry uses a "rule of thumb" of 80% gold recovery to define the transition from a refractory to a non-refractory gold ore. Ones under 80% are considered refractory. In assessing the economic benefit of the extra processing
