Diamonds North reviews Sculptor, Pegasus, Orion results Diamonds North Resources Ltd DDN Shares issued 22,903,688 Feb 20 2004 close $ 1.58 Monday February 23 2004 News Release Also Teck Cominco Ltd (C-TEK) News Release Mr. Mark Kolebaba of Diamonds North reports DIAMONDS NORTH RESOURCES LTD.: HIGH DIAMOND COUNTS AND LARGE STONES RECOVERED FROM SCULPTOR Diamonds North Resources has released the diamond results from the Sculptor, Pegasus and Orion kimberlites, which are centrally located along the 20-kilometre Galaxy structure on the Blue Ice property, Victoria Island. These results are from the 2003 Blue Ice exploration program which was jointly financed by Diamonds North and Teck Cominco Limited. From the Sculptor kimberlite, 724 diamonds were recovered from a 514.15-kilogram composite sample collected from three separate trenches over a 330-metre strike length. The high diamond counts recovered from this sample are associated with an anomalously high proportion of large stones. A total of 191 diamonds (26 per cent) classify as macrodiamonds (at least one dimension greater than 0.5 millimetre) and 48 of these stones measure more than 1.0 millimetre in at least one dimension. Five of the recovered stones measure greater than two millimetres in at least one dimension. From the Pegasus kimberlite, 30 diamonds were recovered from a 220.8-kilogram composite sample obtained from two trenches located 150 metres apart. Five of the diamonds (17 per cent) classify as macrodiamonds and three of these measure greater than 1.0 millimetre in at least one dimension. From the Orion kimberlite, five diamonds were recovered from a 16.42-kilogram composite sample collected from two trenches spaced 86 metres apart. One of the five diamonds is classified as a macrodiamond.

Sculptor in particular, demonstrates a very encouraging diamond size distribution with 25 stones occurring on or above the +0.85-millimetre screen. Two of the largest Sculptor diamonds remain on the +1.70-millimetre screen. The Pegasus sample yielded a relatively small population of diamonds, however, one of the stones is large, remaining on the +1.18-millimetre screen.

This result exceeds the 2002 diamond count for Sculptor which returned 254 diamonds from a 208.58-kilogram sample. The colour and clarity of the diamonds recovered from the 2003 Sculptor and Pegasus samples are summarized in table 4 below. The diamond population from Sculptor is dominated by white transparent stones. Of the six pink diamonds recovered in 2003, four are classified as macrodiamonds. The presence of pink diamonds in Sculptor is consistent with the 2002 diamond results where two pink stones (one of which qualified as a macrodiamond) were reported. Also notable, the Pegasus diamond population is dominated by white transparent stones with no translucent or opaque stones reported.

These magnetic signatures range in width from 25 to 75 metres and up to 2.0 kilometres in strike length. The discovery of Orion in 2003 was the result of geological prospecting. Orion is exposed on surface as a zone of discontinuous frost heaved hypabyssal kimberlite boulders over a strike length of 100 metres and a width of up to one metre. Hand trenching at Pegasus failed to reach bedrock, however, sample material was collected from subcrop and frost heaved boulders. Two of three trenches excavated at Sculptor successfully exposed in situ kimberlite revealing true widths of 1.2 to 1.5 metres. In addition to trenching, the Sculptor and Pegasus bodies were drill tested in 2003 to obtain geometrical data of the bodies at depth. Drill holes BI-03-18 and BI-03-19 were drilled from the same location at -50 degrees and -70 degrees inclinations to test the Sculptor kimberlite at depth. The drill holes intersected 0.7 metre and 2.06 metres of kimberlite from the subvertical body. The core and trench samples are both described as medium-grained olivine macrocrystic hypabyssal kimberlite. Drill hole BI-03-20 (-60 degrees) tested the Pegasus kimberlite and intersected 2.3 metres of very altered, coarse grained, olivine macrocrystic hypabyssal kimberlite below one of the Pegasus surface trenches. Kimberlite samples were collected and logged under the supervision of qualified geoscientists. Samples were securely sealed in solid containers and shipped by air to SGS Lakefield in Ontario. SGS Lakefield's standard caustic fusion diamond recovery method was used for all samples. SGS Lakefield is accredited by the Standards Council of Canada to the ISO 17025 standard for specific registered tests. D.G. Gill, PGeo, is the qualified person as defined by National Instrument 43-101 for Diamonds North Resources, and was responsible for implementing the 2003 Blue Ice program and providing quality control on all data returned.
