Shear reports additional diamonds from KAHUNA
Shear
Minerals Ltd. (SRM:TSXV) and
Stornoway Diamond Corporation (SWY:TSX) today announced additional macro and
micro diamond recoveries from the 2007 drilling of the Kahuna Kimberlite dyke
at the Churchill Diamond project in Nunavut.
In 2007 at Kahuna, 30
drill-holes from 18 set-ups totaling 2,333m were drilled along a 4.5km strike
length of the kimberlite dyke to provide a better understanding of its size and
geometry. A total of 142m of kimberlite was intersected, with single intercepts
ranging from 1.0m to 11.8m down-hole. Based on these intercepts the Kahuna
kimberlite is a vertical dyke averaging 2.6m in true width. Drill core samples
totaling 206.3 kg were processed and 1,071 diamonds, including 99 macro
diamonds, were recovered. Results are listed below:

In addition, samples were

modeling. A total of 288.5 kg was processed with 1,619 diamonds, including 215
macro diamonds, being recovered. Results are listed below:

All samples were
submitted to the Saskatchewan
Research Council Geoanalytical Laboratories (“SRC”) accredited to
the ISO/IEC 17025 standard by the Standards Council of Canada as a testing
laboratory for diamond analysis using caustic fusion.
“We have
consistently recovered high diamond counts from both drilling and sample
pitting along strike, confirming the homogeneous nature of the Kahuna
dyke,” says Shear President and CEO Pamela Strand. “These results
will be used in conjunction with all the other data sets to assist us in an
overall interpretation of the Kahuna kimberlite.”
All diamonds are being
categorized by Mineral Services Canada in Vancouver
in order to assess the population. A final report is pending.
The Churchill Diamond Project is owned 58.14% by Shear and 41.86% by
Stornoway and is comprised of the diamond rights to more than two million acres
located near the communities of Rankin Inlet and Chesterfield Inlet in the
Kivalliq region of Nunavut.
Work is presently focused on continued exploration of new promising indicator
mineral trains and geophysical anomalies as well as the evaluation of a system
of significantly diamond-bearing, vertically-emplaced kimberlite dykes that
have returned sample grades of up to 2.18 carats per tonne. Pamela Strand
