Platinum Group Announces Waterberg Discovery Expands

Tuesday, May 08, 2012

Platinum Group Announces Waterberg Discovery Expands09:19 EDT Tuesday, May 08, 2012VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwire - May 8, 2012) -Platinum Group Metals Ltd. (TSX:PTM)(NYSE Amex:PLG) ("Platinum Group" or the "Company") announces that its Waterberg discovery, in a newly found part of the Bushveld Complex of South Africa, has expanded significantly with further drilling. Step-out drilling has confirmed thick, consistent mineralized zones for a minimum of 1.2 kilometres of apparent strike length and a horizontal distance of 1.43 kilometers along a 20 degree dip. Additional thick reefs or mineralized layers have also been identified in vertical section and all zones remain open for expansion, deeper, shallower and along strike. Drilling is continuing with 8 rigs on a 250 meter by 250 meter grid with some larger scale step out intercepts planned. Additional assays are expected shortly.The first discovery at Waterberg was made at 660 meters deep. From there, the layers have been traced up dip to a depth of 200 meters. Continued drilling is targeting even shallower intercepts. This would make the layers potentially accessible with decline ramps rather than costly vertical shafts. At greater than 3 meters thick, the mineralized layers are very attractive for potential mechanized mining. The project is 49.9% owned by Platinum Group Metals. Japanese state exploration company JOGMEC is a 37% joint venture partner and the balance is held by a South African empowerment company.Recent assay results, in addition to assays for the previously announced T1 and T2 zones, demonstrate that new "T0" and "T3" layers can be correlated between boreholes. The "T" mineralization has strong correlation features to each layer and all of the "T" zones have a distinctive metal ratio of approximately 30% platinum, 50% palladium and 20% gold. Lower down in the vertical sequence, assays from multiple boreholes have now identified a lower "F" reef near the footwall, with a thickness varying between 9 to 27 meters. The F reef has similarities to the more typical North Limb, Platreef mineralization in grade tenure at 40% platinum, 55% palladium and 5% gold.Average ThicknessAverage GradeZoneMeters2PGE+AuNumber of InterceptsT02.631.808T14.293.067T23.794.0212T31.962.5012F17.001.662The "T" mineralization is within an upper sequence of the Main Zone of the Bushveld Complex. The "F" reef is near the floor of the Bushveld Complex.At this early exploration stage, all correlations are subject to further study. The lithological make-up of the T-horizons, their grade thickness tenure, and metal ratios of the Waterberg discovery is unlike other regions of the Bushveld and therefore possibility represents a new environment. There are significant soil anomalies in platinum, palladium, chrome, nickel and copper on the property that are not explained by the current exploration drilling and mineralized layers. Further reconnaissance drilling is planned to test these areas.BackgroundThe Bushveld Complex is host to 80% of the world's platinum and has been mined for the past 90 years. Many of the mines on the traditionally mined layers are deep. Costs, labour and safety have been significant issues recently. Zimbabwe, also a source of platinum, has recently required firms to give up control of their mines.The South Africa Mineral and Petroleum Resources Development Act in 2004 encouraged exploration under a "use it or lose it" system, similar to most of the world, and new areas have been opened up to exploration. The new Waterberg discovery is a good example of direct foreign investment from Canada and Japan teaming up with South African expertise to make new discoveries, directly encouraged by the new Act. Excellent geological potential exists in South Africa, just a short distance from the known trends. In addition to the Platinum Group Waterberg Project, JOGMEC, Itochu, and JGC Corporation from Japan have also made an investment in the Ivanplat's project in the North Limb where thick new mineralization has also been found. The opportunity for nearer to surface platinum with increased safety from mechanized mining in a new environment is very exciting. Given the dropping production of some of the current players and the World's essential need for platinum in catalytic converters and industry, the North Limb developments are of great interest. Certainly these developments are "more down to earth" than the recent suggestions of mining on asteroids for platinum.
