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.
