New Diamond Discoveries on Amaruk
|
| |
VANCOUVER, February 15, 2006 - Diamonds North Resources Ltd. (TSX-V: DDN) have confirmed the discovery of a second diamond bearing kimberlite on the Company's 100% owned Amaruk property in Nunavut.
This second kimberlite, named Qavvik, is represented by a 4 hectare magnetic anomaly that has yielded positive diamond results. Ninety one diamonds or 1.5 stones per kilogram were collected from a 60.28 kilogram sample (Table 1). These results have prompted the expansion of the 2007 core drilling program, designating Qavvik as a candidate for mini-bulk sampling.

Table 1. Qavvik Diamond Results
Sieve Size (mm) Total
Weight (kg) 0.075 0.106 0.150 0.212 0.300
Qavvik 60.28 36 27 15 8 5 91
Approximately 70% of the recovered diamonds are octahedrons and 95% of the diamonds are white in color. The three largest stones measure 0.51mm x 0.43mm x 0.36mm, 0.51mm x 0.46mm x 0.42mm, and 0.51mm x 0.43mm x 0.32 mm.
"The diamond counts are exceptional and even better then we had expected," says Mark Kolebaba, president and CEO of Diamond North Resources. "What's exceptional is despite the diamond losses we anticipated from the RC drilling, the diamond yield is high." A certain amount of diamond loss is expected with this type of reverse circulation (RC) drilling. The down-hole hammer impacts the rock 1,400 times per minute and high pressure air pushes sample material upward at speeds approaching 110-kilometres per hour.
The lack of stones remaining on screens above the 0.300 mm sieve is likely the result of the RC drill pulverizing the material and the relatively small sample size.
Reconnaissance RC drilling has proven to be a cost-effective kimberlite discovery tool that verifies whether geophysical targets are kimberlite and if they contain diamonds. This is important given that there are more than 400 targets on the property, 25 of which are within a 10-kilometre area around Qavvik.
The results outlined in Table 1 are from the first of two drill holes into the Qavvik kimberlite. An additional 400 kilograms collected from the second drill hole are currently being processed for diamonds and results are pending. Mark Kolebaba further states "In light of these results, we are looking forward to further evaluating the Qavvik kimberlite with a core rig."
In addition to results from Qavvik, a 246.84 kilogram RC drill cutting sample from Umingmak (the first diamond bearing kimberlite on Amaruk), yielded 27 diamonds or approximately 0.1 stones per kg. The RC drill hole intersected almost 30 metres horizontal distance across Umingmak. The Umingmak kimberlite is estimated to be three hectares in size.
The diamond results from the Umingmak kimberlite are shown in Table 2 with the results from outcrop samples collected in 2005. The outcrop samples yielded approximately 0.28 stones per kilogram, nearly three times more than the RC drill cuttings, potentially due to the diamond loss in RC drilling. In addition, the outcrop sample of similar weight yielded 20 stones on or above the 0.212 mm sieve, while the RC sample yielded two.
Table 2. Umingmak Diamond Results
Sieve Size (mm)
Umingmak Weight 0.075 0.106 0.150 0.212 0.300 0.425 0.600
(kg)
RC Cuttings 246.84 6 13 12 2 0 0 0
2005 Outcrop 239.08 - 22 18 14 4 2 0
2005 Outcrop 362.69 - 43 41 10 8 3 1
The Umingmak sample is comprised of four down-hole intervals for a total of 60 metres. Approximately 85% of the diamonds in the sample were recovered from the uppermost interval. The single drill hole was located about 136 metres from the center of the outcrop occurrence. Visual inspection of the kimberlite recovered by the drill indicates it appears to be of similar character to the kimberlite observed at surface.
Umingmak has been identified as a target for core drilling in 2007.
Kimberlite RC samples were logged in secure facilities at the field camp by geoscientists. Samples were securely sealed in solid containers and shipped to SGS Lakefield Research in Ontario for processing. The RC results presented here were processed by SGS Lakefield Research using their standard caustic fusion diamond recovery method. The 0.075 mm sieve was added to evaluate potential breakage during drilling. The Umingmak sample was passed over a 0.25 mm sieve prior to splitting on a riffle splitter and one half of the Umingmak material was processed. The Qavvik sample was not sieved or split, and all material from the drill hole was processed by caustic fusion. SGS Lakefield is accredited by the Standards Council of Canada to the ISO/IEC Guide 25 standard for specific registered tests.
Bruce Kienlen (P.Geol) and Graham Gill (P. Geo) are Diamonds North's qualified persons reviewing the data for these projects.
Diamonds North is a dynamic successful exploration team focused on strategically advancing diamond opportunities and is determined to discover Canada's next diamond mine.
