Beatrix, a conventional mining operation, consists of three operating shafts: No. 1 Shaft, No. 3 Shaft, and No. 4 Shaft. The No. 1 Shaft will remain open in support of No. 3 Shaft while No. 4 Shaft is in the process of being placed on care and maintenance.
Beatrix also holds 27Mlb of uranium resources contained in the Beisa Reef.
In 2022, after significant disruption in Q2, SA gold operations negotiated an inflation-linked three-year wage settlement. A decision to close down some loss-making and end-of-life operations, namely the Beatrix 4 shaft and the Kloof 1 processing plant, was made during the fourth quarter. |

Summary:
Beatrix is a deep level underground gold mine located along the northern and southwestern margins of the Witwatersrand Basin in South Africa. This mine is typical of the many Witwatersrand Basin operations, which have been the primary contributors to South Africa’s production of a significant portion of the world’s recorded gold output since 1886.
The orebodies at Beatrix are laterally continuous with relatively long-range predictability. This lends to clear patterns of mineralisation governed by sedimentary characteristics.
The Beatrix Reef (BR) was originally exploited as the main orebody, but has since changed, with the main production coming from the VS5 (Elsburg Formation), the Aandenk (AAR) and Kalkoenkrans (KKR) Composite Reefs.
In general, the Composite VS5/AAR Reefs ranges between 130cm and 350cm in width. The orebody is shallow dipping at 10º – 15º, with typical open fold structures. In most cases the reefs are deemed to be bottom loaded, with most of the gold grade concentrated along the basal contact.
Summary:
Beatrix, a conventional mining operation, consists of three operating shafts: No. 1 Shaft, No. 3 Shaft, and No. 4 Shaft. The ore-body is accessed using vertical shaft systems down to 26 Level (the lowest working level at No. 3 Shaft), approximately 1,350m below surface. Mining predominantly takes place from No. 3 Shaft. The No. 1 Shaft will remain open in support of No. 3 Shaft while No. 4 Shaft is in the process of being placed on care and maintenance.
The Beatrix operation exploits two primary reefs, namely the VS5/Beatrix reefs (VS5/BXR) at the base of the Eldorado Formation and the Kalkoenkrans Reef / Aandenk Reef (KKR / AAR) at the base of the Aandenk Formation.The orebodies are laterally continuous with relatively long-range predictability. This leads to clear patterns of mineralisation governed by sedimentary characteristics. The VS5/BXR forms the bulk of the planned mining at 75% with the remaining 25% mined from No. 4 Shaft on the KKR/AAR.
Beatrix, a shallow to intermediate-depth operation, mining at depths of between 700m and 2,200m below surface.
Three vertical shaft systems are in place to provide access to the underground workings from surface. No. 1 and No. 3 Shafts to the south at the main mine site are situated close to the operational metallurgical plant. No. 4 Shaft is situated approximately 10km away and has its own No. 2 Plant which is currently on care-and-maintenance. Where mining continues below the current infrastructur ........
