High Diamond Counts and Large Stones Recovered from Sculptor
|
| |
Vancouver, February 23, 2004 - Diamonds North Resources Ltd. (DDN-TSX Venture) announces 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 funded 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%) classify as macrodiamonds (at least one dimension greater than 0.5mm) and 48 of these stones measure more than 1.0mm in at least one dimension. Five of the recovered stones measure greater than 2mm 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%) classify as macrodiamonds and 3 of these measure greater than 1.0mm in at least one dimension.
From the Orion kimberlite, 5 diamonds were recovered from a 16.42 kilogram composite sample collected from two trenches spaced 86 metres apart. One of the 5 diamonds is classified as a macrodiamond.
Table 2 shows the largest 3 stones from the samples collected at the Sculptor and Pegasus bodies.
Full square mesh sieve diamond results for the three kimberlite bodies are presented in Table 3 below. Sculptor in particular, demonstrates a very encouraging diamond size distribution with 25 stones occurring on or above the +0.85mm screen. Two of the largest Sculptor diamonds remain on the +1.70 mm screen. The Pegasus sample yielded a relatively small population of diamonds, however, one of the stones is large, remaining on the +1.18mm screen.
The 2003 diamond results for Sculptor demonstrate the presence of larger stones and a favorable diamond size distribution with increasing sample size. 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 2 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.
The central Galaxy Structure consists of the Sculptor, Pegasus and Orion kimberlites, which are a series of en echelon dykes represented by linear magnetic anomalies (A map of the Galaxy Structure is available on the Company's website; https://diamondsnorthresources.com/s/Diamond_GeologicalInfo.asp ).
These magnetic signatures range in width from 25-75 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 1 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° and -70° inclinations to test the Sculptor kimberlite at depth. The drill holes intersected 0.7 metres and 2.06 metres of kimberlite respectively from the sub-vertical body. The core and trench samples are both described as medium grained olivine macrocrystic hypabyssal kimberlite. Drill hole BI-03-20 (-60°) 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 utilized for all samples. SGS Lakefield is accredited by the Standards Council of Canada to the ISO 17025 standard for specific registered tests.
Mr. D. G. Gill, P.Geo. is the Qualified Person as defined by National Instrument 43-101 for Diamonds North Resources Ltd. and was responsible for implementing the 2003 Blue Ice program and providing quality control on all data returned.
Diamonds North Resources Ltd. is a diamond exploration company with more than 12 projects covering over six million acres in Canada's Nunavut and Northwest Territories. Diamonds North's projects include early stage drill targeting to more advanced kimberlite evaluation.
