WINSPEAR RESOURCES LTD. - ABER RESOURCES LTD. - Diamonds
Recovered by Caustic Fusion Analyses

Market News Publishing, Tuesday, July 15, 1997 at 10:00

Randy C. Turner, President and Director of Winspear Resources Ltd., is
pleased to report on diamonds recovered by caustic fusion analyses of
kimberlite dyke intersections encountered during the Spring drilling
program in the Snap Lake area of the Camsell Lake project, NWT. The
project area is situated 140 miles northeast of Yellowknife and is a joint
venture between Winspear Resources Ltd. (57.3%) - the operator - and Aber
Resources Ltd. (42.7%).
During this program, thirteen drill holes intersected kimberlite in a
restricted area about 1 km2 on the west side of Snap Lake. A total of
137.14 kg of kimberlite from these intersections was submitted to Lakefield
Research Limited for diamond analyses. Three of these intersections were
also treated for recovery of indicator minerals. Of the total diamonds
reported, 383 diamonds were recovered and described by Lakefield Research
Limited while 18 diamonds were recovered from the indicator mineral
concentrate and were described by Winspear's Senior Mineralogist who has
more than 20 years experience in this field. Some general characteristics
of these diamonds are as follows:
//st
A. Grade:
The weighted average grade of the thirteen intersections has been
calculated as follows:
Macro diamonds (one dimension >0.5 mm) = 3.69 carats per tonne
B. Colour: The colour of recovered diamonds is as follows:
White 43.7%
Off-white 3.2
Grey 1.0
Yellow 39.2
Off-yellow 1.5
Amber 7.2
Brown 0.5
Green 2.7
Pink 1.0
Of note is the high proportion of yellow diamonds and the presence of
pink and green diamonds in this assemblage.
C. Clarity: Diamonds from the kimberlite intersections have been
described as follows:
Transparent = 87.8%
Translucent = 11.7%
Opaque = 0.5%
//et
All yellow diamonds have been verified as natural diamonds using Raman
spectrometry by the Surface Science Department, University of Western
Ontario. These results were independently corroborated by Lakefield
Research Limited's personnel and by Winspear's Senior Mineralogist.
Although the number and size of recovered diamonds from kimberlite
dyke material are too small to meaningfully extrapolate any parameter to a
larger population of larger diamonds, the Joint Venture is sufficiently
encouraged by these results to collect a larger sample of this material for
further testing.
The Summer field program on the Camsell Lake property is presently
underway. Winspear personnel together with three Russian geologists headed
by Dr. N. Pokhilenko have commenced a program of follow-up sampling in the
Snap Lake area as well as in other parts of the property.
Diamond analyses of core submitted to Lakefield Research from the
kimberlite intersected at CL 186 are expected within two weeks and will be
reported when received.
