Name of the Project
Burnstone gold project.

Location
Balfour area, in Mpumalanga, South Africa.

Project Owner/s
Sibanye-Stillwater.

Project Description
The Burnstone project is a low-cost, extensively predeveloped gold asset, which was previously operated under Great Basin Gold.

Existing infrastructure includes a functional metallurgical facility; an established tailings storage facility; an equipped and functional decline shaft and trackless decline; surface infrastructure, such as offices, workshops and compressors; and extensive underground development and infrastructure.

The relatively shallow underground mining operation will mine the Kimberley reef to an average depth of about 550 m below surface (deepest 1.05 km).

The life-of-mine (LoM) is estimated at 22 years.

The project will produce about 138 000 oz/y of gold at steady state with a LoM to 2044.

Potential Job Creation
At the end of the first half of 2023, there were 740 people on site.

Net Present Value/Internal Rate of Return
The last optimised project evaluation showed a 20% internal rate of return and a net present value of R1.3-billion at a gold price of R800 000/kg (2022 real terms).

Capital Expenditure
Total project capital of R2.8-billion (from 2021 onwards) and preproduction capital of R1.5-billion.

In Sibanye’s annual results for the year ended March 31, 2024, Sibanye reported that it had spent about R2.7-billion on Burnstone. For 2024, planned project capital for Burnstone is R390-million, which pertains to critical work that will continue to ensure a successful ramp-up after the project's delay.

Planned Start/End Date
The timeline to steady-state production has been delayed from December 2025 to August 2026.

Latest Developments
Capital investment has been deferred, with stoping and development activities ceasing, apart from the main shaft decline development.

All construction has also been suspended, except the completion of the surface conveyors, including the new waste conveyor, with planned completion at the end of May 2024, and the support of Settler No 1 and Clearwater Dam No 1 and 2, with planned completion at the end of June 2024.

In the quarter ended March 31, 2024, R210-million was spent on the project.

The project, following the deferral of capital expenditure as announced in February 2024, also requires restructuring to align with the reduction in planned capital activities. An S189 consultation process on the restructuring of the Burnstone operations is in progress.

Key Contracts, Suppliers and Consultants
