Evander Mines consists of 8 Shaft underground mine, a tailings retreatment operation Elikhulu and projects: Egoli project, Rolspruit, project, Poplar project, Evander South project.

8 Shaft
The Kimberley Reef is an oligomictic, pebbly conglomerate and comprises a composite sequence of channel sediments that define longitudinal gravel bars and sand bars with pebbly veneers. The reef in the area strikes in an east-west direction and dips to the north at about 10°. The area is also divided by two major normal faults, striking in an east-north-east to west-south-west direction. The reef thickness varies from a waste on contact up to a 50cm well-developed oligomictic conglomerate. Average reef thickness is 35cm within the 8 Shaft vicinity. High gold values in the Kimberley Reef are mostly located at the base of the unit and are associated with the presence of carbon and some visible gold on the footwall contact.

Mineralisation
Palaeo-placer and braided stream-type sedimentary deposit scavenged gold from the hinterland and underlying deposits. Mineralisation is concentrated in robust conglomeratic and carbonaceous units.

Gold is associated with disseminated sulphides in the form of pyrite. High grades occur where the reef is characterised by carbon specks or bands.

Elikhulu
The ore being treated at Elikhulu originated from the previously mined and metallurgically treated Kimberley Reef from the Winkelhaak, Leslie/Bracken an ........

Evander Mines consists of 8 Shaft underground mine, a tailings retreatment operation Elikhulu.

8 Shaft
Mining method: Conventional breast, scraper mining.

An underground complex consisting of vertical and decline shaft systems. Gold-bearing reef is mined from the 8 Shaft pillar, approximately 1.6km below surface and from 24 Level, some 2.4km below surface. Ore is transported through the decline shaft systems to 15 Level. From there, the ore is transported across to Evander Mines’ 7 Shaft (7 Shaft), where it is hoisted and conveyed to the Kinross metallurgical plant.

The 8 Shaft pillar mining, however, only covers approximately 0.3km2 of the total 8 Shaft area. During the reporting period, mining occurred in the 2 Decline area on the western side at a depth of 2,300m to 2,500m below surface as well as at the 8 Shaft pillar at a depth of 1,600m below surface.

All underground mining development and infrastructure placement for the mining of 24 Level progressed, with initial mining on 24 Level commencing during the reporting period. Furthermore, an independent environmental engineering contractor commissioned phase 1 of the underground refrigeration plant within the mined excavation area created on 24 Level during the reporting period. Phase 2 of the refrigeration plant construction is expected in the following reporting period. Phase 1 of the project enables mining of both the 24 Level F line stopes and mining of the 24 Level B, C ........
