Sunday August 20, 10:07 am Eastern Time S.Africa's Harry Oppenheimer dead at 91 (UPDATE: adds condolence message from ANC, paras 6-7, opening of website, para 11) By Lucia Mutikani JOHANNEBSURG, Aug 20 (Reuters) - South African mining magnate Harry Oppenheimer, former chairman of Anglo American Corp and De Beers Consolidated Mines , died on Saturday, company officials said on Sunday. He was 91. Anglo American Plc (quote from Yahoo! UK & Ireland: AAL.L) chairman Julian Ogilvie Thompson said in a statement that Oppenheimer died on Saturday evening after a short illness. ``South Africa has lost one of her greatest sons,'' Thompson said of the businessman and politician who inherited South Africa's biggest private fortune from his father, Sir Ernest Oppenheimer, founder of the gold and diamond conglomerate. Anglo American described him as one of the world's leading businessmen. ``Few people weilded power as gracefully as Harry Oppenheimer. Never dictatorial, his style rather was one of rational argument and persuation and his influence on the course of politics in South Africa, as well as business, was as remarkable as it was pervasive,'' Thompson said. The ruling African National Congress (ANC) said Oppenheimer had made a significant contributed to the building of the South African economy. ``As we mourn his passing away, we encourage his colleagues in business to take over where he left and continue with his good work,'' said ANC spokesman Nat Serache. Oppenheimer was chairman of Anglo American Coproration for 25 years and chairman of De Beers for 27 years until he retired from those positions in 1982 and 1984 respectively. He was a member of both boards of directors from 1934, retiring from the Anglo American board after 48 years and from the De Beers board in 1994 after serving 60 years. ``There will always be those who say he could have done more. Essentially he would have agreed with them, accepting, sadly that people's achievements seldom match their aspirations,'' said Thompson. Anglo American said it would open a website -- www.harryoppenheimer.org.za -- for condolences at around 1500 Gmt. Born on October 28, 1908, in Kimberly, a diamond mining town in South Africa, Oppenheimer was educated in South Africa and England. He served a long apprenticeship at the side of Sir Ernest Oppenheimer and on his father's death in 1957 took over the chairmanship of Anglo American and De Beers. ``Harry Oppenheimer steered the world's diamond industry through a tremendous, though not uninterrupted, era of growth,'' said Thompson. Anglo American listed on the London Stock Exchange in June 1999 and was immediately ranked in the top 25 of the FTSE 100 index with a market capitalisation of $12 billion, a far cry from the one million pounds with which Oppenheimer's father had used to set up the company. Oppenheimer is survived by his wife, Bridget, his son Nicholas, current chairman of De Beers, and a daughter, Mary. PHIL

Will, Part of the problem here is the fact that the grade does improve with depth, over the better drilled portions above 500 metres. That trend does not appear to continue, but neither can it be said that the grade drops off with greater depth at this juncture. Correct. (grade x thickness) plots are routinely carried out in advanced exploration and mining situations. The exercise I went through by doing a (thickness x microdiamond count/100) calculation, and then contouring those results, is a variation on that method(the assumption is that grade can be confidently related to micro diamond counts). This analytical method provides meaningful, important and practical economic applications, especially in a mine planning situation(where is the "heart" or "sweet spot" of the deposit? or where should we start mining to get our money back in the least amount of time and provide the greatest return on investment etc). Added benefits include useful insights and rational in deciding the direction of exploration, and in this particular case, geological criteria for where I may wish to invest next and why. It is only since the most recent exploration this year, including the VRP and the high level of disclosure by WSP that has made this kind of outside analysis possible. My interpretation of the contoured (grade x micro diamond/100) plot is as follows: 1. The source is a deep seated fissure spacialy related to the N.N.E. trending Snap lake fault. 2. The kimberlite was injected into low angle faults(perhaps some minor horizontal displacement along the highest low angle fault off set the vertical continuation of the fissure and Snap Fault to surface, forcing the kimberlite to move laterally into low angle displacement faults, forming at least two stacked sheets). 3. An intersecting N.W. trending fault may have localized thickening. This would indicate that the thickest areas must be restricted to the areas along the fissure AND where it is intersected by N.W. trending faults. 4. The best fit axis of the (grade x thickness) plot represents the strike of the fissure. The strike of this fissure is towards the south corner of SUF and DSP claim blocks. 5. Grade persists laterally but the sheets thin as distance from the fissure and cross cutting faults increases(proximity to source is important). This analysis leads me to believe that the SUF MacKay claim block holds the most promise or potential for discovery of significant tonnage with comparatively thicker, sweet spots localized along the fissure. regards, teevee
