Blue Ice Property Update
Vancouver, February 28, 2005 - Diamonds North Resources Ltd. (DDN - TSX Venture) announces that planning for the 2005 Blue Ice exploration program is well underway. The bulk of the program will comprise drill testing of approximately 75-100 targets and airborne magnetic surveying over two areas on the property. The $3 million program is funded and operated by Teck Cominco Limited.
Approximately 30 targets have been prioritized for core drilling and more than 75 targets have been identified for possible testing using a reverse circulation drill rig. This is an aggressive drill program designed to test a large number of targets over a relatively short period of time. To maximize the drill season, mobilization of equipment and supplies for the program is scheduled to start on April 15. The reverse circulation drilling is planned to start in early May and the core drilling is scheduled to begin approximately 2 weeks later.
Selected targets include magnetic anomalies and several recently identified EM anomalies. Airborne geophysics will focus on previously untested portions of the property using magnetics.
Diamond results for approximately 1000 kilograms of kimberlite from the King Eider and Turnstone kimberlites are expected around the end of March. Diamond results for two dykes located 25 metres east of the main Snow Bunting kimberlite and a new kimberlite called H-1 which is located along the central King Eider kimberlite structure have been received.
Four core samples collected from two hypabyssal kimberlite dykes, east of the main Snow Bunting kimberlite, were combined to form two composite samples. Sample SB04-1, weighing 46.66 kilograms, yielded 3 diamonds while sample SB04-2 returned 2 diamonds from a 24.6 kilogram sample with one stone measuring nearly 1.0mm in one dimension.
A 21.07 kilogram core sample from the previously untested H-1 kimberlite returned one stone. The sample mainly comprised kimberlite recovered from a 1.72 metre (true width) drill intercept. Full Square Mesh Sieve diamond results for the Snow Bunting dykes and H-1 kimberlite samples are shown below in Table 1.

* Largest Stone - 0.94mm x 0.46mm x 0.31mmDue to a favorable diamond size distribution returned from drill core during 2003 (see NR #03-37), the 2004 drill program at Snow Bunting was designed to further test the geometry and diamond potential of the kimberlite to the east of the 2003 drill site. The two holes drilled in 2004 intersected two fine grained hypabyssal kimberlite dykes, ranging from 0.60 metres to 5.26 metres true width (assuming a vertical body), with few indicator minerals. These lithologies are markedly different from the 2003 kimberlite intersections. The contrasting diamond counts between the 2003 and 2004 results can likely be attributed to different kimberlite phases.
Kimberlite intersections were logged in secure facilities at the field camp by qualified Teck Cominco geoscientists and subsequently sent to Vancouver for sampling. Two thirds of each kimberlite sample was collected for microdiamond analysis utilizing a rock saw with a synthetic diamond blade. Samples were securely sealed in solid containers and shipped to Kennecott Canada Exploration Inc.'s Mineral Processing Laboratory in Thunder Bay, Ontario. Kennecott's standard caustic fusion diamond recovery method was utilized for all samples. Kennecott Canada Exploration Inc.'s Mineral Processing Laboratory is accredited by the Standards Council of Canada to the ISO/IEC 17025 for specific registered tests.
