At Marula three boreholes were drilled on the lower
portion of an extension of the Driekop mining right as
part of the agreement with the Anglo Platinum/ARM
joint venture. One borehole was completed at Afplats
on the Kareepoort/Wolvekraal extension. In the
Imbasa/Inkosi area, drilling continued and an additional
20 boreholes were completed. At the Tamboti Project
17 boreholes were drilled on Portions 4, 5 and 6 of
Kalkfontein in conjunction with Two Rivers and in
fulfilment of prospecting right obligations.

Zimplats stepped up its exploration programme at
Ngezi during the year with detailed drilling at Portals
5W and 5E in preparation for a feasibility study. At
Portals 7 to 10, a one kilometre grid of boreholes was
completed, and north of Portal 10 widely spaced
drilling continued (4 by 1km). Geotechnical drilling for
ventilation shafts and underground crusher positions at
Portal 3 was also undertaken.
At Mimosa, the focus was on the characterisation of
shallow oxide ore at both North and South Hill and
38 boreholes were drilled.
Offshore exploration activity continued at a modest
level against a background of recovery in the broader
exploration sector but with limited good quality PGM
opportunities worldwide. The main focus area was
Canada where, in conjunction with Wallbridge Mining
and HTX Minerals, we continued to explore for PGMs
in the Sudbury Basin and in the Mid Continental Rift
area around Thunder Bay.
Further encouraging results were obtained in drilling at
the Wallbridge Milnet/Parkin project, which led to the
decision by Implats to vest its 50% share and continue
exploration on a fully fledged joint venture basis.
HTX continued its target generation work on the Mid
Continental Rift area. Some 2 200m of drilling returned
disappointing results with no significant mineralisation
intersected. However, additional targets have been
identified for follow up. At Hele, a joint venture with
HTX, additional gravity and soil gas geochemical
surveys have identified areas for further prospecting.
Implats entered into an agreement with Northern
Shield Resources to further investigate surface
occurrences of PGM mineralisation in the Labrador
In southern Africa our strategic alliance with Impact
Minerals focused on a PGM opportunity in Swaziland.
Elsewhere, Implats maintained a watching brief
on exploration developments worldwide and
numerous exploration opportunities presented to
us by junior exploration companies were assessed.
