5.4.2.5 Airborne Geophysics
In 2006 Omegacorp completed a high resolution helicopter borne magnetic and
radiometric survey (line spacing of 200m). The survey was effective in confirming and
extending ground radiometric anomalies, as well as in delineating additional “en
echelon” radiometric anomalies that may represent mineralised splays related to the
Mavuzi “Fault Corridor” (Figure 5-9).

5.4.2.6 Soil Sampling
In 2008, Omegacorp completed a small soil sampling grid (20m x 100m) over an area
in an attempt to delineate the source of a rock grab sample that returned an anomalous
Pt value (OMG4024 – 1.9 g/t Pt and 546 g/t Cu) from an ironstone related to a coarse
grained pyroxenite. Samples were selected from the “B” Horizon at a depth of
approximately 20-30cm and sieved to -180µm. Samples were sent to ALS Chemex in
Johannesburg, prepared and assayed for the PGE suite as a multiple element suite.
Results were very poor and failed to replicate or delineate any significant PGE
anomaly. Exposures of coarse grained sulphide-bearing pyroxenites were observed by
MSA near an old quarry located approximately 2.5km to the north east of this soil grid,
