Columbia Yukon Explorations Inc.: Additional Significant Moly Assays Received

WEST VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 7, 2007) - Columbia Yukon Explorations Inc. (the "Company") (TSX VENTURE:CYU) is pleased to announce that it has received assay results for the first nine holes of its ongoing 2007 drill program on the Company's "Storie" molybdenum property located in northern British Columbia. The Storie Property lies south of the former Cassiar Mine townsite and is accessible by paved highway to Cassiar and then five kilometres of all weather gravel road.

As part of its 2007 drill program, the Company has thus far completed 35 drill holes (11,000 metres of drilling). To date, the Company has received assay results for the first nine drill holes. The Company will report the rest of the assay results when they are received, however, the results from the first nine drill holes are as follows:

All of the first nine drill holes lie east of the zone that was drilled in 2006, and therefore, were not used in the calculation of the NI 43-101 Mineral Resource estimate prepared by Watts Griffis & McOuat Limited, Consulting Geologists and Engineers of Toronto, Ontario ("WGM"). As announced in the Company's news release of July 5, 2007, WGM calculated an inferred resource of 101.6 million tonnes grading 0.067% Mo (1.07% MoS2). This calculation was made using a 0.35% Mo (0.56% MoS2) cut off grade, a 1.5:1 waste to ore stripping ratio and a maximum open pit mining depth of 325 metres.

Although narrower intercepts were encountered, the MoS2 grades from seven of the first nine drill holes were in excess of the 0.56% MoS2 cut off grade used for the initial resource area by WGM in their NI 43-101 Mineral Resource estimate. As well, these additional holes have thus far extended the mineralization 100 metres to the east along the Crone Fault, which remains open to the west.

The Company has four drills operating on the Property which are presently drilling infill holes within the initial resource area for the purpose of upgrading the current inferred resource to an indicated and measured resource. When the infill drilling is completed, the drills will continue testing the east and west extensions to the initial resource area. Additionally, the Company is negotiating to secure a fifth drill which could be on the Property by mid September.

As well, the Company currently has a geophysical crew on the Property completing an Induced Polarization ("IP") Survey. The IP survey is intended to locate the position of other mineralizing structures similar to the Crone Fault. The primary structure to be tested will be the X-Fault, which is to the south of the Crone Fault.
