The mineralised layers of the Waterberg Project:
• The mineralisation is hosted by sulphides that are apparently magmatic in origin.
• The mineralised layers can be relatively thick, often greater than 10 m.

PGM mineralisation within the Bushveld package underlying the Waterberg Project is hosted in two main layers: T Zone and F Zone.

The T Zone occurs within the Main Zone just beneath the contact of the overlaying Upper Zone. Although the T Zone consists of numerous mineralised layers, three potential economical layers were identified: TZ, T1, and T0. They are composed mainly of anorthosite, pegmatoidal gabbros, pyroxenite, troctolite, harzburgite, gabbronorite, and norite.

The F Zone is hosted in a cyclic unit of olivine rich lithologies towards the base of the Main Zone towards the bottom of the Bushveld Complex. This zone consists of alternating units of harzburgite, troctolite, and pyroxenites. The F Zone is divided into the FH and FP layers. The FH layer has significantly higher volumes of olivine in contrast with the lower lying FP layer, which is predominately pyroxenite.

The mineralisation generally comprises sulphide blebs, net-textured to interstitial sulphides and disseminated sulphides within gabbronorite and norite, pyroxenite, and harzburgite.

Within the F Zone, basement topography may have played a role in the formation of higher grade and thicknesses where embayments or large-scale changes in ........

The Waterberg Project will be an underground mining operation accessed via declines from surface. The mine design is based on using the sublevel longhole stoping mining method (Longhole) to extract M&I Mineral Resources contained in the T Zone and F Zone and backfilling the mined voids with paste backfill. Longhole is a highly mechanised, high productivity, and low-cost bulk mining method that uses equipment and processes widely used in the global mining industry.

The Waterberg Project mineralised zones have an overall strike length of approximately 8.8 km extending from the T Zone in the southwest to the F-North Zone in the northeast. Considering the extensive strike length and relative proximity and separation of the zones, the operation was divided into the following three mining complexes:

• The South Complex that includes T Zone and F-South;
• The Central Complex that includes F-Central;
• The North Complex that includes F-North, F-Boundary North, and F-Boundary South.

The vertical distance between mining blocks will be 100 m. Individual longitudinal and transverse stopes will be limited to a maximum vertical height of 40 m. The maximum longitudinal stope strike length will be 20 m, while the stope width for transverse stopes will be 20 m along strike. In thicker parts of the ore, there will be a need to limit the maximum stable length of transverse stopes to 40m.

Due to the relatively shallow depth at the top elevati ........
