Canabrava Diamond Corporation and Diamonds North
Resources Ltd.: More Macrodiamonds Recovered from King
Eider Kimberlite Pipe, Hadley Bay Project, Victoria
Island
VANCOUVER, BRITISH COLUMBIA--Canabrava Diamond Corporation
(CNB-TSX Venture) and Diamonds North Resources Ltd. (DDN-TSX
Venture) announced today that more macrodiamonds have been
recovered from three additional kimberlite samples processed from
the King Eider kimberlite pipe, Hadley Bay Project, Victoria
Island. The King Eider kimberlite is part of a diamondiferous
cluster, which includes the Jaeger, Turnstone, Sanderling and
Pintail kimberlites.
Diamond samples CNB01019 and CNB01021 were recovered from -50
degree inclined drill hole HD02-12 that intersected multiple
phases of kimberlite in more than 100 metres of core. Sample
CNB01015 was recovered from -50 degree inclined drill hole
HB02-13, which was drilled at 180 degrees to drill hole HB02-12.
The core was separated into six sub-samples representing each of
these kimberlite phases. The results from the current three
samples are listed in Table 1 and the results of the first three
samples were announced in Canabrava News Release dated October
22, 2002.

Macrodiamonds are present in two samples, with the largest stone
recovered from sample CNB01019. This stone has three dimensions
exceeding 0.5 millimetre: 1.14x0.68x0.69 millimetres. The
detailed diamond recoveries in the individual square mesh screen
categories are listed in Table 2.

Canabrava President George Read states, "The size and abundance
of macrodiamonds in King Eider encourage us to conduct further
evaluation of this kimberlite."
The King Eider kimberlite pipe was originally located using
airborne geophysics and a recent detailed ground geophysical
survey, carried out prior to drilling, has shown that King Eider
is a large complex kimberlite. The magnetic anomaly measures 200
by 300 metres. The detailed geophysical survey, the core logging
and diamond analysis indicate that King Eider is composed of
multiple diamondiferous kimberlite phases.
Mark Kolebaba, President of Diamonds North states, "The nature of
the diamond size distribution is encouraging as it demonstrates
the presence of larger stones and indicates that the pipe is
under-sampled."
In light of the demonstrated potential for eclogitic diamonds in
the Victoria Island kimberlites the sample sizes were maximized
and virtually all core has been submitted for diamond processing.
Representative samples of each lithological type have been
retained for petrography and indicator mineral recovery.
Samples CNB01025 (41.3 kilograms, Pluto kimberlite), CNB01032
(98.6 kilograms, Apollo kimberlite) and CNB01064 (18.3 kilograms,
Diana kimberlite) did not contain microdiamonds. Results are
pending from additional samples of the Apollo and Diana
kimberlites.
Kimberlite drill core was logged and sampled in secure facilities
in the field camp. Sample bags were placed in solid, sealed
containers and shipped by air to SGS Lakefield Research 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/IEC Guide 25 Standard
for specific registered tests.
