Focus on Kliprivier
Previous exploration work on the Kliprivier project has been carried out by at least five companies since 1969 with 30 boreholes drilled, some to in excess of 1,000m deep. An inferred UG2 resource of 109.6 Mt @ 2.3 g/t (3PGE+Au) containing 7.6 Moz 3PGE+Au (undiscounted) or 6.46Moz applying a 15% discount factor from surface over a 6km strike length on the 3,300ha permitted share of Kliprivier has been defined (based on information compiled by Mr Allen Maynard – Member of the Australasian Institute of Mining and Metallurgy (AusIMM) and the Australian Institute of Geoscientists (AIG). In addition, there is a lower chromite band with an estimated potential of 4.0 to 4.5Moz of target PGM mineralisation (Source Nkwe – Annual Financial Statements 2008). This target mineralisation is conceptual in nature and future exploration may or may not define this in whole or in part.
Realm Resources appointed the MSA Group (geological consultants) and Remote Drilling Services to conduct a limited scale drilling program to better define the near surface resource potential at its Kliprivier platinum project on the Eastern Limb of the Bushveld Igneous Complex. Six holes were drilled along the 6 km outcrop of the UG2 chromite horizon to intersect mineralisations at approximately 100 metres below surface.
The drilling was aimed at defining the location of UG2 horizon and assessing the potential for additional platinum group metal (PGM) mineralisation in the UG2 chromitite band and any other mineralisation that could possibly be associated with the contact with the floor rocks.
In addition to the above, the MSA Group compiled a database consisting of all the previous geological and sampling information to assist with the design of a more detailed follow up drilling program to upgrade the near surface resource potential and to conduct preliminary mine planning and economic modelling for the potential development of an open pit operation along strike of the UG2 horizon.

Low cost open pit mining approach
The near surface UG2 Reef (less than 200m depth) may be amenable to lower cost open pit or shallow underground mining. Initial reviews of the data indicated that the Kliprivier project might best be exploited via open pit methods with ore treated at a nearby low capital and operating cost plant. Additionally, further, there may be ways to enhance returns via the potential extraction and sale of by-product chromite.

In addition, examination of the bore cores has confirmed the presence of the more typical single UG2 reef horizon as well as a wider reef or "split reef facies" where the UG2 mineralisation occurs in two horizons separated by 3 to 10 metres of host rock. This will be further investigated in the next round of exploration.
