Barberton Mines comprises Fairview Mine, Sheba Mine, New Consort Mine.

The mineralisation at Barberton Mines is classified as Achaean epigenetic hydrothermal lode gold deposits within a granite greenstone terrain. The distribution and localisation of these orebodies in the BGB can be largely attributed to the combined influence of thermal metamorphism and structural deformation. The BGB has produced approximately 11Moz of gold since the first discovery in the early 1880s. Barberton Mines has produced more than 75% of the total production from the BGB.

Mineralisation at Barberton Mines is typically continuous in the short- to medium-range on strike with long-range geological and grade continuity being experienced down-dip. Gold occurs in either vein-hosted ore lode deposits or as free milling gold associated with fine grade sulphides, mainly pyrite and arsenopyrite.

The Barberton ores are thus mineralised shears with gold occluded in sulphide minerals. The sulphides often occur as massive assemblages in the shear structure. Lower-grade ore, in the wall rock, forms as a result of the alteration process during fluid flow and is associated with disseminated sulphide minerals. A late stage of gold mineralisation occurred in brittle fractures with the formation of quartz veins. These quartz veins often contain free gold in visible clusters.

Barberton Mines comprises Fairview Mine, Sheba Mine, Consort Mine.

Fairview Mine produces approximately 46% of Barberton Mines’ annual gold production, with Consort Mine, Sheba Mine and the BTRP producing 8%, 22% and 24%, respectively.

The availability of deep-seated high-grade orebodies and lower-grade shallower resources from the mines provide options for planning in order to maintain the targeted grade/tonnage profile for annual gold production of approximately 100Koz. This also enables the optimal management of cash flows, operating costs and life of the operations at Barberton Mines from an early stage in the mine planning process.

The mining methods used at Barberton Mines’ underground operations are semi-mechanised up-dip cut-and-fill and up-dip room and stick mining. An estimated 16% of gold is recovered by sweeping and vamping contractors focusing on historically worked-out areas and mining high-grade remnant zones of ore.

Fairview Mine
An underground mining complex consisting of adits and subdecline shaft systems. Gold-rich orebodies are mined from near surface to approximately 1.7km below surface at the MRC 11-block orebody. Ore is transported through three decline shaft systems to 11 Level. From here, the ore is crushed and transported via an aerial bucket system to the Fairview metallurgical plant.

During the 2023 reporting period, Fairview Mine continued its focus on optimising the extraction and succe ........
