Name of the Project
Bengwenyama platinum group metals (PGMs) project.
Location
Eastern Limb of the Bushveld Complex, in Limpopo, South Africa.
Project Owner/s
Southern Palladium.
Project Description
A scoping study has shown the project to have very attractive economics, with results justifying a prefeasibility study (PFS) already under way.
The project aims to extract PGMs from the upper group two (UG2) and Merensky reefs, which constitute one of the very few remaining areas within the Bushveld Complex where economically viable PGMs deposits remain unexploited.
The scoping study proposes a two-million-tonne-a-year UG2 reef underground mining operation using hybrid mining, with conventional stoping supported by on-reef mechanised development and ore clearance.
The life-of-mine for only the UG2 reef is estimated at 36 years, with a total of about 52-million tonnes mined – about 10.9-million ounces platinum, palladium, rhodium, ruthenium, iridium, osmium and gold (7E or 6E+gold), for an average production rate of 330 000 oz/y platinum, palladium, rhodium, ruthenium, iridium and gold (6E or 5E+gold) basis. This ignores residual value beyond modelled life or any exploration upside.
The project includes:
- construction of a flotation and spiral plant to deliver PGM and chrome concentrates from a conventional plant, with an estimated 200 000-t-a-month ore feed design capacity. A 75 µm grind size is envisaged.
- construction of a dry-stack tailings storage facility conforming to Global Industry Standards on Tailings Management requirements.
- connection to the nearby national grid power substation and construction of a 132 kV overhead powerline to supply (based on initial indications) of about 43 MVA peak demand.
- connection to an existing licensed, bulk water supply pipeline, located at the entrance road to the project. Water supply will be supplemented with available ground- and surface water.
- comprehensive integration of all on-site infrastructure, encompassing site access roads, office and administrative buildings, engineering workshops, stores, a guardhouse, surface-water storage facilities and other supporting facilities.
Potential Job Creation

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate of, $1.04-billion and an internal rate of return of 24%, with a payback of from the start of plant production of 4.5 years.
Capital Expenditure
$408-million.
The project is fully funded.
Planned Start/End Date
The completion of the PFS and associated resource drilling is planned to be completed during the second half of 2024.
Latest Developments
Southern Palladium has completed an initial resource drilling campaign as part of a PFS, and all assays have been received.
Eighty-two drillholes were completed, totalling 30 746 m – including 50 reef deflections.
Drilling results for the UG2 reef have consistently confirmed the initial inferred mineral resource grades and prill split – thus confirming the robustness of the UG2 reef and the broader project, the company has said.
Additional samples have been collected for metallurgical testwork to confirm the recovery of by-product chromite from the UG2 reef.
Footwall mineralisation of the Merensky reefs has been observed, which is now being investigated further.
An updated mineral resource estimate will be released in the third quarter of the year, which will facilitate the start of mine planning for the PFS.
