VANCOUVER, BRITISH COLUMBIA is pleased to provide analytical
results for an additional 8 diamond drill holes (DDH), totaling
2020 metres (6,627 feet) from the recently completed 75 hole
drilling program at its 100% owned Turnagain Project, located 70km
east of Dease Lake in British Columbia. Results for 27 of the drill
holes have now been released with the analytical results for the
remaining 48 holes to be reported when they are received.
Results are reported from five complete and one partial hole in
the Northwest zone and from two holes in the Duffy zone area. Drill
hole locations can be viewed on the attached map.
"Although the holes in the vicinity of the Duffy zone were not
encouraging, the holes in the Northwest zone returned some very
pleasant surprises," said Mark Jarvis, President of Hard Creek
Nickel. "The platinum-palladium values were well above what was
anticipated within sections of drill core above 0.50% total nickel.
This is significant because this is the first time we have
encountered this relationship within drill core on the
property."
"These results open up the potential for developing areas within
the Horsetrail deposit which host both nickel and
platinum-palladium mineralization," said Mr. Jarvis. "The potential
to include platinum and palladium as a portion of our overall
resource could be significant. Close spaced drilling will be
required during the next drill season to determine the significance
and extent of this mineralization."
Holes 07-196, 197 and 198 were drilled as step-out holes along
the western and southwestern margins of the Northwest zone
mineralization where the favourable dunite-wehrlite lithology is
becoming diluted by dykes, hornfels and pyroxenite. Although nickel
mineralization is generally weaker than in the core of the
Northwest zone, hole 07-197 contained a 32m interval averaging 0.29
percent total nickel, suggesting a possible extension to the
west.
Holes 07-199, 202 and 205 were drilled towards the centre of the
Northwest zone to confirm the continuity of the mineralization at
depth to the north and to test zones of inferred mineral resource.
These holes encountered both higher grade nickel mineralization and
two intervals of significant platinum-palladium mineralization.
Hole 07-199 was terminated in mineralization grading 0.56 percent
total nickel and 689ppb (0.69 grams/tonne) combined platinum and
palladium. Hole 07-205 intersected an 8m interval averaging 0.70
percent nickel and 475 ppb (0.48 grams/tonne) combined platinum and
palladium. Results are pending for the bottom 290 metres of this
hole and an additional six holes drilled in the Northwest Zone.
Both holes 07-168 and 07-200 drilled along the southern margin
of the Duffy area encountered thick intervals of dunite without
significant mineralization.
The total nickel values reported in the table below include
nickel in both sulfide and non-sulfide minerals.
DDHs 07-196, 197 and 198 were drilled as step-out holes and
07-199, 202 and 205 were drilled as infill holes within the
Northwest zone of the Horsetrail deposit:

True widths are estimated to be approximately 80 percent of
reported core intervals. Samples for analysis were generally 4
metres in length of split NQ-size core. Reference pulps with known
nickel and copper values were inserted every 25 core samples and
rock blanks inserted every 30 samples to monitor laboratory
performance as part of the QC/QA program.
Total nickel, copper, cobalt and sulfur values were determined
by ICP emission spectrometry following four acid digestion of a
representative pulp sample. Platinum and palladium values were
determined by ICP emission spectrometry following lead-collection
fire assay fusion of a 30 gram pulp. All analytical work was
conducted by Acme Analytical Laboratories Ltd., an ISO 9001
registered facility, located in Vancouver. International Plasma
Labs (iPL), an ISO 9001 registered facility, also located in
Vancouver, is carrying out check analyses on ten percent of the
samples.
The Turnagain Nickel Project resource has been estimated in
early 2007 (see February 12, 2007 News Release for details) with
the measured and indicated resource estimated at 428.5 million
tonnes grading 0.23% total nickel (0.17% nickel in sulfides) and
0.011% cobalt and an additional inferred resource of 742.9 million
tonnes grading 0.23% total nickel (0.17% nickel in sulfides) and
0.011% cobalt. Sulfide nickel grades are based on ammonium
citrate-hydrogen peroxide leach analyses. Ammonium citrate-hydrogen
peroxide leach analyses for nickel provide a good estimate of
nickel grades present in sulfide form and display good correlation
with recoveries in metallurgical testwork. When compared with
conventional analyses for nickel, the ammonium citrate-hydrogen
peroxide leach results range from 60% to 90% of total nickel
values. Only the nickel in sulfides is expected to be recoverable
by froth flotation. Mineral resources that are not mineral reserves
do not have demonstrated economic viability.
