Location

GGM is located in the Geita region of Tanzania, approximately 1,200km from the main Tanzanian business centre of Dar es Salaam. It falls within the Lake Zone of northwestern Tanzania, approximately 120km west of Mwanza and 4km west of the town of Geita. The mining lease area falls within the Archaean Sukumaland Greenstone Belt of the Lake Victoria goldfields.

Mining methods and key infrastructure

The Geita gold deposits are mined as a multiple open pit and underground operation, with ore production from Star and Comet, Nyankanga and Geita Hill underground mines, and from Nyamulilima open pit.

Open pit mining is by conventional truck and shovel methods, while the underground mining method is a combination of long hole open stoping and transverse open stoping. Cemented aggregate fill is used at Nyankanga to backfill the primary stopes and allows for the mining of secondary stopes. Ore is hauled from the Nyamulilima open pit (22km) and from Star and Comet (17km), Nyankanga (4km) and Geita Hill (2km) underground operations to the central run-of-mine (“ROM”) pad by the Geita surface mining fleet.

The processing plant circuit contains a primary gyratory crusher, secondary and tertiary crushers, a SAG mill, a ball mill and 12 leach tanks. Geita’s ore processing method is a conventional CIL process with a throughput capacity of 5.4Mtpa. This is coupled with a gravity circuit using two Knelson concentrators.
