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.

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
Diamondloss 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.

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.
