Canabrava Diamond Corp. and Diamonds North Resources Ltd.: Macrodiamond Recovered, Turnstone Kimberlite, King Eider Cluster, Hadley Bay Project, Victoria Island.Business Editors VANCOUVER, British Columbia--(BUSINESS WIRE)--Jan. 21, 2003 Canabrava Diamond Corporation (TSX TSX Toronto Stock Exchange (TSE before April, 2002) TSX Transfer from Stack Pointer to Index TSX True Space Extension Venture:CNB CNB Czech National Bank CNB Centro Nacional de Biotecnologia CNB City National Bank CNB Citizens National Bank CNB Croatian National Bank CNB Chloronitrobenzene CNB Corresponsales No Bancarios (Spanish, Colombia) ) and Diamonds North Resources Ltd. (TSX Venture:DDN (Defense Data Network) An Internet-based global communications network created by the U.S. Department of Defense. In April 1996, users were moved to the more modern Defense Information Systems Network (DISN) made up of NIPRnet (Non-classified IP Router Network) and ) announced today that one macrodiamond and two microdiamonds have been recovered from the Turnstone kimberlite kimberlite: see diamond. kimberlite or blue ground Dark, heavy, often fragmented igneous rock that may contain diamonds in the rock matrix. , Hadley Bay Project, Victoria Island. The Turnstone kimberlite is part of the diamondiferous King Eider kimberlite cluster, which includes the King Eider, Sanderling, Jaeger and Pintail pintail Any of four species (genus Anas, family Anatidae) of sleek, long-tailed, long-necked dabbling ducks that are swift fliers and popular game birds. The common, or northern, pintail (A. kimberlites. Small kimberlite fragments overlying overlying suffocation of piglets by the sow. The piglets may be weak from illness or malnutrition, the sow may be clumsy or ill, the pen may be inadequate in size or poorly designed so that piglets cannot escape. the Turnstone kimberlite were collected to form a 20 kilogram sample (D-03-02). The sample mass was limited by the amount of kimberlite material available on surface. Results of sample D-03-02 are listed in Table 1.

The macrodiamond has three dimensions exceeding 0.5 millimetre: 1.03x0.71x0.64 millimetres. Mark Kolebaba, President of Diamonds North states, "The recovery of a plus one millimetre diamond from a three-stone population is very encouraging as it demonstrates the presence of larger stones and warrants further work for Turnstone." The detailed diamond recoveries in the individual square mesh screen categories are listed in Table 2.

Canabrava President George Read states, "This macrodiamond recovery from the Turnstone kimberlite is consistent with results from the nearby King Eider kimberlite, emphasizing the favourable macrodiamond abundance of this kimberlite cluster." This kimberlite occurrence was originally located using airborne geophysics and a recent detailed ground geophysical survey has shown that the Turnstone kimberlite dyke has a strike length of over 1.5 kilometres. Presently, the width of the body has not been determined. Kimberlite material was collected and bagged in the field. Sample bags were placed in solid, sealed containers and shipped by air to SGS SGS Société Générale de Surveillance SGS Symantec Gateway Security (appliance) SGS School of Graduate Studies SGS Subgrid Scale SGS Singapore Government Securities SGS Shell Global Solutions Lakefield Research in Ontario. SGS Lakefield's standard caustic fusion diamond recovery method was used for all samples. SGS Lakefield is accredited accredited recognition by an appropriate authority that the performance of a particular institution has satisfied a prestated set of criteria. accredited herds cattle herds which have achieved a low level of reactors to, e.g. by the Standards Council of Canada The Standards Council of Canada is a Crown corporation based in Ottawa, Ontario, and is Canada's member body of the International Organization for Standardization.
