Slide 3: Local Geology – Western Bushveld Limb
· Main Zone – consists of norites grading upwards into gabbronorites. It includes several mottled anorthosite units towards the base and a distinctive pyroxenite, the Pyroxenite Marker, two thirds of the way up. This marker-unit does not occur in the project area, but is evident in the adjacent BRPM
Slide 4: Merensky footwall units
FW6 is overlain by a uniform norite (FW5), with a thickness of 4.1m. It appears to thin towards the north to about one metre. FW4 is a mottled anorthosite 40cm thick, with distinct layering at its base. FW3 is an 11m-thick uniform leuconorite. FW2 is subdivided into three sublayers. FW2(b) is a 76cm
Slide 5: Project Geology
The Merensky and UG2 isopach decreases from 60m to 2m at outcrop position as clearly illustrated by the section in Figure 7. There is also a subcrop of the Critical Zone against the Main Zone rocks. Project Geology The sequence of the BIC within the WBJV area is confined to the lower part of the Mai

Slide 7: Item 8: Deposit Types
ITEM 8: DEPOSIT TYPES The most pronounced PGE mineralisation in the Project Area occurs within the Merensky Reef and is generally associated with a 0.1–1.2m thick pegmatoidal feldspathic pyroxenite unit. The Merensky Reef is generally also associated with thin chromitite layers on either/both the to
Slide 8: UG2 Facies Types
UG2 Facies Types The UG2 CL is composed of a choromitite layer and generally has a base feldspathic pyroxenite pegmatoid and certain overlying chromitite layers termed leader and triplets. Most of the intersections encountered in the PTM exploration campaign have no basal pegmatoid but do have FW13

Slide 14: Statistical Analysis
Statistical Analysis Descriptive statistics in the form of histograms (frequency distributions) and probability plots (to evaluate the normality of the distribution of a variable) were used to develop an understanding of the statistical relationships. Skewness is a measure of the deviation of the di

Slide 35: Variography
Variography Variograms are a useful tool for investigating the spatial relationships of samples. Variograms for channel width (cm), 4E cm.g/t and 4E, per domains, were modelled during the estimation process. The table below summarises the variogram model parameters for the different reefs and domain
Slide 36: Variogram models and grade estimation
All variograms are omni-directional spherical semi-variograms. Table 11 summarises the 4E content and Resource cut width variograms, which have a modelled grade continuity range of ~270-700m for the Merensky Reef and a modelled grade continuity range of ~245-600m for the UG2 CL. The nugget effect is
