Columbia Yukon Explorations Inc.: SGS Reports That "10 KG SampleFlotation Tests on Variability Composites Produced Very Good MolyGrades and Recoveries in the Batch Testing"

WEST VANCOUVER, BRITISH COLUMBIA--(Marketwire - November 18, 2008) -
Columbia Yukon Explorations Inc. (the "Company" or "Columbia Yukon")
(TSX VENTURE: CYU)(FRANKFURT: VOR) is pleased to announce favourable
results from the Phase 2 metallurgy program on the Company's Storie
property molybdenum deposit located near Cassiar in northern British
Columbia.
 
SGS Mineral Services (SGS Canada Inc.) of Vancouver, B.C. ("SGS") was
engaged by Columbia Yukon to investigate options for the recovery of
molybdenum (via flotation) from the Company's Storie property. Phase
1 of the metallurgy program conducted by SGS involved sample
preparation, grindability testing, mineralogical characterization
through QEMSCAN analysis, rougher kinetics testing and batch cleaner
testing on a master composite and also batch cleaner testing and
locked cycle testing on four variability composites. In addition, the
SGS metallurgy program included an environmental testing program. The
Phase 1 program results were announced in the Company's September
25th, 2008 news release.
 
SGS has now successfully completed Phase 2 of the preliminary
metallurgical testing of ore taken from the Storie property
molybdenum project and the Company is extremely encouraged by the
results of this program. The Phase 2 program followed SGS's initial
Phase 1 recommendations, which were designed to optimize test results
using a larger 10 KG sample size (as opposed to the 2 KG Phase 1
sample size). The Phase 2 testing was performed on four composites
compiled from over 100 samples taken from all areas of the deposit
and SGS has reported the following results to the Company:
 
- The results of the 10 KG flotation tests on four variability
composites achieved a concentrate grade of 37% to 50% Mo and a
recovery of 75% to 84%;
 
- The master composite (composite B, which is a combination of all
samples) achieved a 50.15% Mo concentrate grade, while recovering
81.2% of the contained molybdenum.
 
The SGS technical metallurgical report prepared for Columbia Yukon's
Storie property molybdenum deposit can be reviewed on the Company's
website (www.columbiayukon.com).
 
This news release has been reviewed and approved by Mr. Arnold
Pollmer, P.Geo., who is acting as the Qualified Person for the
Company's Storie property molybdenum project in accordance with
regulations under NI 43-101.
