Tromp Read Replies (1) | Respond to of 2522 Rex Diamond Mining Corporation is pleased to announce the discovery of a new kimberlite in its 100% owned permit to the east of Tenoumer in Mauritania. Rex has 90,000km² of 100%-owned exploration permits on the core of the Archean Craton and a further 13,426km² held in joined venture with De Beers. As a result of the summer exploration programme conducted within our various permit areas in Mauritania, Rex is pleased to announce the discovery of a new kimberlite body. The kimberlite was located by dedicated pitting and soil sampling efforts, as the body itself has only a weak magnetic signature. Kimberlite outcrops are visible over a length of at least 300m. Several kimberlite samples of 50kg - 100kg each are being taken and will be analysed for their micro- diamond content. The discovery of this latest kimberlite body has resulted in the recognition of further potential kimberlite targets. The company's drill rig is now being positioned in the area. In the Akchar permit, our joint venture partner De Beers has begun exploration work in the form of an aeromagnetic survey. Recently, De Beers acquired the 3,426km² that was relinquished by Rex, when the permit holdings were revised in accordance with the new Mauritanian mining code. As agreed under the joint venture, the 3,426km² have now been included in the Akchar joint venture, making the total area held by the joint venture partners, 13,426km². Under the terms of the agreement, De Beers is obliged to spend US$24m over 5 years or produce a bankable feasibility study, in order to acquire a 60% interest. In addition to the above, Rex Diamond Mining Corporation is pleased to announce preliminary results from exploratory drilling conducted in its 100%-owned metal exploration permits in Mauritania. In February 2000, while exploring for kimberlites, Rex identified two gossans, with anomalous metal concentration in soil samples. During the summer months of 2000, a core drilling programme was conducted to determine the nature of mineralisation of the two gossans at depth. The first batch of results has now been received for platinum and palladium only, and shows a concentration of more than 1g/tonne over 18m thickness for the first portion of the drill core. We are now awaiting the full results of the core analysis for both the other metals (PGMs, precious and base metals) and the remaining core samples. The full results of these drillings are expected in the coming weeks. Rex Diamond Mining Corporation is a vertically integrated diamond mining and marketing company.
