The plant expansion project will include installation of a larger mineral sizer/primary crusher to increase front-end capacity, a second elution circuit and gold room, and additional carbon-in-leach tanks to provide appropriate leach resi-dence time at increased throughputs, thereby maintaining planned gold recover-ies at the back end. These modifications are targeted at increasing the plant’s nom-inal throughput from 1.3 million mt/y to 2 million mt/y through one expansion, rather than increasing throughput incrementally via a number of expansions as was originally envisaged.

Twangiza is Banro’s first mine.

Banro’s second mine, Namoya, is now being developed, with production startup scheduled for mid-2013.
