Hard Creek Nickel Turnagain Project Update

VANCOUVER, BRITISH COLUMBIA is pleased to provide an update on
its 100% owned Turnagain Project, located 70 km east of Dease Lake
in British Columbia.
Drilling Update
The largest drilling program in the Company's history has come
to an end for 2007. The camp is winterized and shut down for the
season. The four drilling rigs will remain on site over the winter.
I would like to acknowledge the dedication and hard work of our
exploration team led by Tony Hitchins and Chris Baldys in advancing
our project to its' current state.
During the 2007 field season the Company has drilled 75 holes
for a total of 24,600 metres (80,700 feet). This includes the
collection of approximately 4,275 kg (9,425 lbs) of PQ-sized (2.5
inch diameter) drill core for a variety of crushing, grinding and
abrasion testwork.
The focus of the 2007 drilling program has been to:
- Determine the spatial limits of the Horsetrail deposit with
stepout drill holes,
- Upgrade the confidence in the inferred portion of the
Horsetrail deposit,
- Collect large diameter drill core samples for further detailed
metallurgical testwork,
- Further explore the extent of the PGE mineralization in the DJ
and DB areas, and
- Drill test three exploration target areas; the Mandible,
Central and the Cliff Areas.
Assay results have been received for only 19 of the 75 complete
drill holes. Given the excellent opportunity for mining in British
Columbia and the flurry of drilling activity in the province the
local analytical laboratories are overwhelmed with samples coming
in at record levels (a near 80% increase in sample volumes). As a
result they are approximately 12 weeks behind in delivery times.
Analytical results from our program will be released as they become
available.
Metallurgical Testwork
The next phase of testwork will be primarily directed towards
refining the parameters necessary for projecting actual mill
performance. This testwork will be directed by John Hoffert, P.Eng.
and carried out by Xstrata Process Support (XPS) in Falconbridge,
Ontario and at SGS in Lakefield Ontario.
The XPS testwork will be developed in two phases. The first
phase consists of quantitative mineralogy, mineral processing
flotation testing including QEMSCAN and Microprobe analyses, one
rougher and one cleaner test for mineralogy and metallurgical
alignment. This work will be completed by the end of February
2008.
The second phase of XPS testwork includes locked cycle, open
cycle testing followed by Mini Pilot Plant testing. The Mini Pilot
Plant is unique XPS technology (1 such unit in North America) and
is able to operate in continuous mode with roughing, regrinding and
column flotation at a feed rate of only 10 kg/hr.
The SGS testwork will be focused on completing a variety of
crushing, grinding and abrasion testwork. This work will also be
completed by the end of February 2008.
Additional hydrometallurgical testwork is also being completed
at SGS under the supervision of Dr. David Dreisinger. More work
will follow in 2008.
Updated Resource Estimate and Preliminary Assessment
AMEC Americas Limited of Vancouver, B.C. will audit and update
the Turnagain Nickel Project resource estimate (see news release
February 12, 2007) as part of the updated Preliminary Assessment
(PA). This will be done prior to the receipt of all the 2007
drilling results. It will include all of the drill hole results
reported to date; 19 drill holes for a total of 7,595 metres (24,
918 feet), (see news releases for August 13, 2007 and September 25,
2007). All of these holes are located in the proximity of the
previously proposed "starter pit area" as identified in the
previous 2006 PA. The updated PA is expected by the end of
November.
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 at 428.5 million tonnes grading
0.23% total nickel (0.17% nickel in sulfide) and 0.011% cobalt and
an additional inferred resource of 742.9 million tonnes grading
0.23% total nickel (0.17% nickel in sulfide) and 0.011% cobalt.
Nickel in sulfide 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 excellent 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. Nickel sulfides are expected to be recoverable by froth
flotation. Mineral resources that are not mineral reserves do not
have demonstrated economic viability.
This news release has been reviewed and approved by Neil Froc,
P.Eng., a qualified person consistent with NI 43-101.
