Larger diamond discovered at Buffalo Hills project Ashton Mining of Canada Inc ACA Shares issued 20,836,399 Jan 16 close $6.35 Mon 19 Jan 98 News Release See Pure Gold Minerals Inc (PUG) News Release Mr Donald Sheldon reports Pure Gold Minerals has received further results from mini-bulk samples collected from the K14 complex and a preliminary result from kimberlite K6 at the Buffalo Hills project in north central Alberta. The results include the two largest diamonds recovered to date from the project, one from each of these kimberlites. As presently interpreted, the K14 kimberlite is a roughly circular feature about 400m in diameter (15-18 hectares). It is comprised of a central zone which has been drilled to 200m in depth (termed K14A in the table below) and an apron of variable thickness crater facies material to the north (K14B) and northeast (K14C) of the central zone. Ashton Mining of Canada has now completed at its North Vancouver laboratory the dense media separation analysis of all K14 kimberlite material collected in 1997. The current results were derived from samples which comprise five core drill holes on K14A (4.38 tonnes), four core drill holes (3.33 tonnes) and surface pits (7.03 tonnes) on K14B, and seven core drill holes (2.71 tonnes) on K14C. Results from K14, including those released in Stockwatch November 12 1997, are tabulated below.

The largest diamond is a single crystal, of silvery-grey appearance with many dark inclusions. The largest diamonds previously reported were 0.60, 0.30, 0.28, 0.21, 0.18 carat. The sample size continues to be too small to draw any conclusions as to quality or value of diamonds from K14. These results confirm that K14 contains a population of diamonds of commercial size while continuing to show the high degree of variability between samples reported in the November 12 results. This is not considered unusual given the random distribution of diamonds in kimberlites. For example, initial microdiamond results from drilling by rotary percussion in the K14C area produced high numbers of smaller diamonds, most of which were fragments resulting from breakage of a larger stone or stones. In the current results from K14C only a small number of diamonds were recovered. Significantly larger samples representative of the entire near surface kimberlite will be required to assess any commercial potential. During the initial stages of processing of the K6 samples a 0.76 carat diamond was recovered. This circular crystal is bright yellow, clear and transparent and contains no obvious inclusions. This is an encouraging result suggesting the potential of K6 to host larger diamonds of good quality. Larger samples will be required to determine grade and value accurately. Analysis of K6 samples is continuing. Pure Gold Minerals and Ashton Mining of Canada have an option agreement with Alberta Energy of Calgary whereby Pure Gold and Ashton have the right to earn interests of 15% and 42.5%, respectively in the Buffalo Hills property. Total landholdings, including joint venture lands, comprise 28.3 million acres in north central Alberta. Ashton is the operator of the related exploration programs.
