Angola negotiations continue Pure Gold Minerals Inc PUG Shares issued 26,379,471 Apr 22 close $0.98 Thu 23 Apr 98 News Release Mr Donald Sheldon reports ANGOLA Gold is negotiating with the owners of two diamond concessions straddling the Chicapa River in the Lunda Norte area of Angola. The total area of the concession is 300 sq km. Some areas of the concessions provided 350,000 carats at a grade of 0.4 carats/cubic metres with a 2:1 stripping ratio. The average value is US$200/carat. Pure Gold has paid a deposit to secure an interest in these rights and will make a further payment as soon as the due diligence has been completed. SOUTH AFRICA Agreement in principle has been reached with Thabex Exploration a publicly trading (Johannesburg Exchange) South African diamond exploration company, to acquire an interest in its diamond concession in South Africa. The project, known as the Douglas project, is 450 ha in size and contains 3.65 million tonnes indicated diamondiferous reserves at an average grade of 1.1 carat per 100 tonne at an average expected price of $757.00 per carat. Mining of this project began April 15 1998, and will be increased from the current 100 tonnes per month (from exploration trenching) to a diamond mine, producing at a rate of 50,000 tonnes per month. As soon as due diligence is complete, a further news release on the terms and timing of the project will be made. The two projects represent a further diversification for Pure Gold as it expands its potential for economic diamond production. ALBERTA Further news is expected shortly from the Ashton Mining of Canada/Alberta Energy Company joint venture regarding microdiamond counts in new kimberlites discussed in news release dated March 23 1998

Hi again Violetta- always a pleasure! :: A kimberlite pipe vs. kimberlite rock: (please forgive any inaccuracies here, and also any info you already know!) A kimberlite is simply a sub-volcano, one that originates beneath the lithosphere and bursts through to the surface. The classic kimberlite 'pipe' then is at the historical source, or the throat of the volcano. The kimberlite pipe is the site or structure complex where magma escaped from the mantle upward, by way of some fault or fissure in the earth's crust, to bring diamonds to the surface (if it passes through a diamond stability field, containing diamonds!). Typically, a pipe's physical dimension has been carrot-shaped (esp. in southern Africa), estimated to extend down 2-3km, if uneroded at surface (as it appears in AB). The shape of the kimberlite's surface mag anomalies are then often round or eliptical. -Since kimberlite is of mantle origin, and thus, ultramafic (rock that's rich in magnesium & iron), it will subsequently produce magnetic anomalies, distinct from surrounding bedrock. Kimberlite can be emplaced through multiple phases occurring over a time, or in a one episode eruption (all at some 70-100million+ years ago). Remember that Ashton first thought K14 and K-14B and K-14C were distinct pipes (based on the mag anomalies), but later concluded that they were separate phases of the same pipe, or volcanic structure. Donald Sheldon described K-14C as a "spillover" of K-14. - - - The zones or 'kimberlite flows' described by ShoreGold sound like lava rivers, or something to that effect (?). The rivers of molten kimberlite would flow from the kimberlite pipe or vent (the exit vent where from crater facies explode upward). -- Perhaps the material is a 'tuff' or ring around the volcanic vent (mouth) and/or crater, of kimberlite material. Again I haven't reviewed all they've released. Sounds like they believe it could be an economic deposit in itself (?), but it also sounds like more delineation drilling is necessary. Perhaps SGF already considers the complex to be a pipe (?). ------------ This is just my surface-educated guess, Violetta. Facts are not yet known (i.e., especially by me!). All the best, -j :> PS-- I don't profess to be an expert, by any means!
