Name of the Project
Witwatersrand Basin Project (WBP) – Qala Shallows.

Location
Johannesburg, South Africa. The project is situated about 15 km west of the Johannesburg central business district, in the province of Gauteng.

Project Owner/s
Explorer, developer and producer of high-value precious and base metals West Wits Mining.

Project Description
Qala Shallows is an integral part of the WBP. An updated definitive feasibility study (DFS), released on July 23, 2025, highlights improved results and reinforces the project’s robust value and strong economic fundamentals.

The reefs to be processed during the life of the project are the Kimberley reefs – K9A and K9B.

The total Joint Ore Reserves Committee- (Jorc-) compliant mineral reserves are estimated at 4.6-million tonnes grading at 2.60 g/t for 383 934 oz of gold. The total Jorc-compliant mineral resources for the K9A reef are estimated at 8.1-million tonnes grading at 4.8 g/t gold for 1.2-million ounces of gold, and 10.5-million tonnes at 4.5 g/t gold for 1.5-million ounces of gold for the K9B reef. The mine plan has been optimised with a lower cutoff grade of 1.31 g/t (reduced from 2 g/t in 2023), allowing for the inclusion of additional ore and accelerating the production profile. The project uses a conventional breast mining method in an underhand configuration, considered optimal for the Qala Shallows deposit.

The stopes will be accessed by strike drives developed on the K9B reef horizon and the K9A and K9B stopes will be accessed from this infrastructure. The strike drives will connect to a decline system developed from the existing Qala adit boxcut, located centrally in the mining area and in the footwall of the K9B reef.

Steady-state gold production is estimated at 70 000 oz/y over a 12-year period, an increase from nine years in the 2023 DFS.

Total gold production over the 16.8-year life-of-mine is projected at 944 000 oz, up from 924 000 oz over 17.7 years in the 2023 DFS. The maximum production rate is estimated at 860 000 t/y (2023 DFS: 839 000 t/y), with an average gold production of 56 000 oz/y (2023 DFS: 51 000 oz) and peak production of 75 000 oz in Year 6. The total run-of-mine tonnes are estimated at 10.7-million (2023 DFS: 10.2-million tonnes).

Ore processing will be conducted at the Ezulwini process plant, a subsidiary of Sibanye-Stillwater, on a toll treatment basis. The plant uses carbon-in-pulp for gold recovery.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The updated DFS shows a pretax net present value, at a7.5% discount rate, of $719-million (compared with $367-million in 2023) and an internal rate of return of 93% (compared with 61% in 2023). Payback from the end of the peak funding period is estimated at eight months and at 3.3 years from the start of development.

Capital Expenditure
Peak funding is estimated at $44-million over a 2.6-year period, a reduction from $54-million over three years in the 2023 DFS.

Planned Start/End Date
Not stated.

Latest Developments
The first load-haul-dump unit has been delivered to the site, marking the mobilisation of key equipment. Mining contractor Modi Mining has been engaged, and essential personnel have been hired. All critical infrastructure, including substations and water infrastructure, is now complete. Decline and boxcut rehabilitation, along with on-reef underground access, are also complete.

The first ore, an estimated 3 000 t, was delivered during an early works programme. West Wits is continuing discussions with lenders to finalise the optimal funding mix. Next steps include securing the remaining project funding, continuing equipment acquisitions and contractor mobilisation, and building a 30 000 t gold ore stockpile for consistent delivery to Sibanye-Stillwater’s plant.

Key Contracts, Suppliers and Consultants
Bara Consulting (independent mining engineers, undertaking the DFS review and update); Modi Mining (mining contractor); Industrial Development Corporation of South Africa and Absa Bank (lenders for the syndicated loan facility); and Sibanye-Stillwater’s Ezulwini process plant facility (toll treatment agreement for ore processing).
