Update on Tjate

Jubilee Platinum PLC 04 August 2006 4th August 2006 AIM: JLP JUBILEE PLATINUM PLC ('Jubilee' or 'the Company') Borehole DT7 Intersects Consistently High-Grade Merensky Reef on the Tjate Project, South Africa Jubilee announces results for its borehole DT7 on the Dsjate farm ('Tjate Project') in the Bushveld Complex of South Africa. The borehole was significantly stepped out some 200 metres further east and up dip on reef of the most easterly boreholes DT2 and DT4. Highlights • Merensky reef intersected at a depth of 722.5 metres • The reef showed a weighted average (mother hole plus three deflections) of 7.08g/t 4E (platinum, palladium, rhodium and gold) over apparent 82 centimetres reef thickness • Maximum grade of 11.75 g/t 4E in one deflection over apparent 89 centimetres reef thickness • Average 1.73 platinum to palladium ratio • Average grade and reef thickness is consistent with the overall average of 7.00g/t 4E over apparent reef thickness of 82 centimetres established for the seven holes drilled • Results confirm excellent consistency and continuity of reef dip and extension of reef horizon • Valuable average copper and nickel values of 0.21% nickel and 0.14% copper Detailed results for borehole DT7 are shown in Table 1 below: Table 1 DT7 Results for Merensky reef intersection Apparent 4E Pt Pd Rh Au Ni Cu Pt:Pd thickness g/t g/t g/t g/t g/t % % ratio (cm) Motherhole 80 5.30 2.87 1.69 0.14 0.60 0.21 0.17 1.7 Deflection1 89 11.75 7.20 3.50 0.29 0.76 0.20 0.13 2.1 Deflection 2 80 4.73 2.51 1.62 0.14 0.46 0.20 0.14 1.6 Deflection 3 77 5.95 2.98 2.27 0.17 0.53 0.24 0.13 1.3 Weighted average 82 7.08 3.99 2.31 0.19 0.59 0.21 0.12 1.7 Colin Bird, CEO of Jubilee and Tjate Project Manager, said: 'These latest results confirm the reef dip and provide us with the comfort of having established to date consistent high grade results, combined with good reef thickness, for the Tjate project. Our scoping study, which is near completion, will be updated to incorporate this latest important data.' The Dsjate farm is one of three contiguous farms in the Tjate project, which comprises a total of 5,143 hectares, with an inferred resource of 282 million tonnes containing 66 million ounces of 5 PGE (platinum group elements: platinum, palladium, rhodium, iridium and ruthenium) and gold, of which 22.8 million ounces are attributable to Jubilee. Jubilee has a 25% stake in Tjate and is currently earning in a further 10% interest by expending ZAR14 million towards a bankable feasibility study. SGS Lakefield Research Africa in Johannesburg carried out the analyses of the borehole core samples. This laboratory is SNAS TO169 accredited.
