Diamond Trading N.V. is a minority shareholder of Twin Mining Corporation. The examination was performed on diamonds recovered from the 18.41 tonne sample (86 diamonds + 1mm, 3.644 carats; see press release July, 18, 2001) from the Freightrain pipe on Twin Mining's 100% owned Jackson Inlet property. Diamond Trading N.V. summarized the results of their examination as follows: "The diamonds we examined were from Twin Mining's Freightrain pipe. The diamonds are similar to high quality South African diamonds but without having their characteristic yellow colouring. In comparison to the Slave Craton diamonds (e.g. Ekati and Diavik), which are generally octahedrons with higher occurrence of black piqués (impurities) and maccles (intergrown diamond crystals), the Jackson Inlet sample differs in the total absence of boart, rejections, coated and cubes, which are low-grade and low-yield diamonds. We also noted the absence of small feathers (small diamond crystal flaws) that appear across the range of Slave Craton diamonds. The absence of feathers, impurities and colouring in the better half of the Freightrain sample, combined with their rounded shape will produce high yielding polished diamonds of good lustre, high purity and colour grading. The purity (IF - VVSI) and colour (average F or better) of the sawable (highest yield diamonds) is remarkably high and they represent a much higher proportion of the sample than is current in South African and Canadian kimberlite mine production." Twin Mining is currently carrying out a diamond drilling program on the Freightrain pipe and on other anomalies on the Company's properties. Twin Mining, in addition to exploring the TORNGAT diamond prospect on the east side of Ungava Bay in northern Québec and the Jackson Inlet diamond project on Baffin Island, also holds a gold mining project in Idaho, United States of America.
