Slide 2: Forward Looking Statements
Forward Looking Statements The information in this Presentation contains forward-looking statements. These statements are subject to certain risks and uncertainties that could cause the actual results to differ materially from those included in the forward-looking statements. The forward-looking sta
Slide 3: Cu/PGE
Cu/PGE The diagram shows PGE depletion trends (Cu/Pt+Pd) for the Bushveld Complex and the Highbank Lake Intrusion. Geologist use Cu/(Pt+Pd) as a gauge to measure depletion because Pt and Pd are scavenged much more efficiently than Cu by any sulphide droplets in the magma. Note how the upper portion
Slide 4: Cu/Pd
Cu/Pd The diagram shows Pd depletion trends for 4 other PGE-bearing layered intrusions. Note how again the PGE reefs occur at or very near the stratigraphic level where the rock chemistry changes from being depleted to enriched in PGEs (Pd).
Slide 5: Pt+Pd
Pt+Pd The overall PGE values also give an indication of the proximity to the main PGE reefs. PGE concentrations in the Main Zone of the Bushveld (grey area) are typically around 10-30 ppb and rarely exceed 100 ppb until the Critical Zone is reached just above the Merensky reef. The Highbank data sho
Slide 6: Cr/V
Cr/V Chrome/vanadium ratios are useful in determining how primitive the rock layers are. Generally, Cr becomes more abundant lower in the stratigraphy (more ultramafic) while V decreases. Cr/V ratios are also useful in highlighting stratigraphic levels at which magma replenishment has occurred. Bush
Slide 7: Summary
Summary The geochemical trends and the rock types identified in the drill core to date suggest that the bottom of drill-hole 07HB- 01 is teasingly close to the stratigraphic level where the main PGE-bearing reef should be located. Hole 07HB-05 was drilled in an attempt to intersect the stratigraphy
