Char Kimberlite Yields High Diamond Counts All Drilled
Kimberlites Prove to be Diamondiferous
======================================================================
VANCOUVER, April 24th, 2007 - Diamonds North Resources Ltd. (TSX-V:
DDN) announces high diamond counts from the Char kimberlite discovered
on the Company's 100% owned Amaruk property in the Pelly Bay Diamond
District. A 159.35 kilogram sample from Char yielded 178 diamonds
including 6 macrodiamonds (>0.5mm in at least one dimension).
The Char kimberlite is the second highly diamondiferous kimberlite
discovered on the property. Also highly diamondiferous is the Qavvik
kimberlite which yielded 515 diamonds from a 379 kilogram sample (see
news release NR07-07, March 29th, 2007). Both the Char and Qavvik
kimberlites are targeted for mini-bulk sampling in 2007.
"Five out of five kimberlites drilled on the property are
diamondiferous. Two of the five kimberlites, Char and Qavvik, are
highly diamondiferous with greater than 1 diamond per kilogram. Given
that Char and Qavvik are 35 kilometres apart Amaruk may be the first
big diamondiferous kimberlite field discovered in Canada since Ekati
and Diavik" states Mark Kolebaba, President and CEO of Diamonds North.
The Char kimberlite sample is a composite of drill cuttings from three
depth intervals in a single drill hole. The upper most interval, Char 1
weighing 66.17 kilograms yielded 103 diamonds. A 49.97 kilogram sample
from the second interval yielded 15 stones and 43.21 kilograms from the
lowermost interval produced 60 diamonds. The Char kimberlite sample was
collected using a reverse circulation (RC) drill. A certain amount of
diamond loss is anticipated since a high proportion of this sample is
pulverized (see photo - sample of Char RC cuttings

The diamond sieve data for the Char kimberlite is shown in Table 1.
Sieve Size (mm)
Sample Weight (kg) 0.074 0.105 0.150 0.212 0.300 0.425 Total
Char 1 66.17 17 36 24 12 4 1 *103
Char 2 49.97 1 4 5 2 3 0 15
Char 3 43.21 19 21 14 4 2 0 60
Combined 159.35 37 61 43 18 9 1 178
*9 additional diamonds were recovered below the 0.074mm screen.
Approximately 75% of the diamonds are octahedral in form, 14% of the
recovered stones are fragments and 88% are white. The dimensions in
millimeters for the three largest diamonds recovered from the sample
are: 0.77 x 0.77 x 0.40; 0.77 x 0.40 x 0.40 and 0.68 x 0.40 x 0.43.
The Char kimberlite was penetrated 59 metres with a single drill hole.
The estimated size of the Char kimberlite based on geophysics is 1.5
hectares.
Walrus & Beluga
In addition, results from the Walrus and Beluga kimberlites were
received. A 388 kilogram sample from Walrus yielded 6 diamonds with the
largest diamond remaining on the 0.212 mm screen. The Beluga kimberlite
sample weighing 162.1 kilograms yielded 3 diamonds that remain on the
0.105 mm screen. Though the diamond counts are low, it is significant
that all of the drilled kimberlites to date have proven to be
diamondiferous, indicating that an extensive diamond fertile mantle
exists beneath the property.
The RC drill cuttings were logged in secure facilities at the Amaruk
field camp by geoscientists. Samples were securely sealed in solid
containers and shipped to SGS Lakefield Research in Ontario for
processing. The results presented here were processed by SGS Lakefield
Research using their standard caustic fusion diamond recovery method.
The 0.074 mm sieve was added to evaluate breakage during drilling. The
samples were split on a riffle splitter prior to caustic fusion. SGS
Lakefield is accredited by the Standards Council of Canada to the
ISO/IEC Guide 25 standard for specific registered tests. As part of an
ongoing Quality Control & Quality Assurance program, Diamonds North is
conducting an audit of the results.
Bruce Kienlen (P.Geol) and Graham Gill (P. Geo) are Diamonds North's
qualified persons reviewing these projects. They are responsible for
the design and conduct of the exploration programs and the verification
and quality assurance of analytical results.
