My reading of it is they plan to produce and sell a gold concentrate containing 90% of the gold from sulphide ore then leach the flotation tail (10% of gold that does not float due to sulphide oxidisation).
Flotation tails are to be mixed with historical tailings and leached through the same leach tanks to produce an additional 20,000ozpa from Feb 22.
Very low cost gold production as main costs are pumping and reagents.
