Beatrix, a shallow to intermediate level gold mine, has been producing gold since 1983, in the southern portion of the Free State Goldfields.

Beatrix is located in the Matjhabeng Magisterial District, near the towns of Welkom and Virginia, approximately 240km south-west of Johannesburg, in the Free State province of South Africa. Before the advent of mining the land was used for agricultural purposes and very little natural vegetation remains.

The current mine infrastructure consists of three producing shaft complexes. Mining is focused on open ground and pillars (white areas) of differing reef horizons with the deepest operating level some 2,055m below surface (22 Level at 4 Shaft). The principal mining takes place on the Beatrix Reef (BXR). Additional reefs mined include VS5 Reef of the Eldorado Formation (VS5), Aandenk (AAR) and Kalkoenkrans (KKR).

Mineralisation characteristics

Auriferous and uraniferous palaeo-placer conglomerates, that are locally termed reefs. Laterally continuous with relatively long-range predictability. Clear patterns of mineralisation governed by sedimentary characteristics.

Depositional environment

The palaeo-placer originated from a braided stream environment. The deposition was structurally controlled along a basinal edge.

Infrastructure

Three shaft complexes (one sub-shaft). Two mineral processing plants. All supporting infrastructure to service an operating gold mine.

Mining method

Scattered conventional breast mining, pillar extraction and SRD mining.

Mineral processing

Beatrix makes use of two gold processing plants, both treating underground and surface material
1 carbon-in-leach (CIL) plant processing underground ore and low-grade SRD material
2 CIL plant processing underground ore and low-grade SRD mining
