If I locate the papers I will photocopy them and mail them to you. Or at least locate titles and dates for searching. They should be in my stuff somewhere. I saw the Griffin paper a while back. You could reasearch the V. Sobolev Yakuts reference at your local University Library. Griffin's paper may be at the USGS in Colorado or at UBC or U of Calgary. All papers are at the Kirkland Lake resident geo's office. Other possibilities are Lakehead U and Laurentian in Sudbury. EC<:-}

Twin outlines pair of dike segments at Torngat North Twin Mining Corp TWG Shares issued 73,404,344 Jan 14 close $0.39 Thu 16 Jan 2003 News Release Mr. Hermann Derbuch reports TWIN MINING'S TORNGAT DIAMOND PROJECT DELIVERS ENCOURAGING DI ... Twin Mining has released the results of 15 grab samples from outcropping kimberlite, ranging in weight from 24 kilograms to approximately 100 kilograms, from Torngat North. These results highlight the diamond potential of the Torngat diamondiferous kimberlite dike system that outcrops over a strike length of 37 kilometres and measures up to 2.3 metres in width. Analysis of the diamond results identified two dike segments of 900 metres and 400 metres respectively, with higher stone densities than other sampled parts of the dike. These results, and work to date, relate to exposed dike intervals that strike roughly at right angles to stratigraphy. Cross faults, that are believed to occupy overburden covered valley floors, also intersect dikes at roughly right angles and potential exists for dike width enhancement where dikes and cross structures intersect. Additional surveying and ultimately diamond drilling would be required to evaluate overburden covered sections of dike material. Diamond extraction by caustic fusion (at a cutoff size of 100 microns) selection and description was performed by SGS Lakefield Research Limited which is accredited by the Standards Council of Canada and CAEAL for specific registered tests. A review of the diamond size distribution was performed by AMEC E & C Services Limited.

Of the 197 diamonds recovered, the largest stone measures 1.85 millimetres by 1.25 millimetres by 1.07 millimetres (0.0142 carat). Lakefield describes the diamonds extracted as, "very white, mostly transparent and of high preservation." Previously, three mini-bulk samples, weighing 90.7 tonnes, 57.7 tonnes and 193.2 tonnes, were excavated in the summer of 2000 at sample location AD2, which is four kilometres to the southwest of the 900-metre dike segment Torngat North. For comparative purposes the four largest diamonds extracted from the mini-bulk samples are listed below (see press release April 5, 2001): 4.60 x 4.20 x 3.54 (0.685 ct); 4.97 x 3.87 x 3.40 (0.566 ct); 4.61 x 4.14 x 0.50 (0.193 ct); and 3.50 x 3.32 x 2.10 (0.271 ct). Diamond Trading N.V. of Antwerp, Belgium, which is a minority shareholder of Twin Mining, examined a small parcel of these diamonds (see press release April 5, 2001). In its opinion, the diamonds are of high quality, good crystalline shape, very white and of high purity. The results of the analysis of diamonds appear to be consistent with the results of the mini-bulk sample taken in the fall 2000 and indicate there is no need for a further large sample from this location. AMEC recommended that Twin Mining conduct a desk-top study of existing indicator mineral chemistry data to identify any area of the dike system that has favourable indicator mineral chemistry and that any prospective areas identified through this analysis be sampled to determine microdiamond counts. It was further recommended that any future sampling program incorporate a core-drilling component to investigate potential grade variations at depth. Twin Mining's diamond exploration focus is on its large tonnage potential Jackson Inlet project. Accordingly, management is currently pursuing options, including joint venture participation, to advance the Torngat project. John Lindsay, PEng, AMEC's principal metallurgist, is Twin Mining's qualified person for diamond size distribution analysis, and Dallas Davis, PEng is Twin Mining's qualified person for the field component, as defined by National Instrument 43-101. Twin Mining's kimberlite core samples, from the Jackson Inlet 2002 phase 1 exploration campaign, are currently being processed by Lakefield. Results will be announced as soon as they are available. After the conclusion of the oversubscribed flow-through financing of $3.3-million the company is proceeding with the financing of approximately $2-million in non-flow-through money early in 2003.
