Mesa Uranium Signs Definitive Joint Venture Agreement with Energy Fuels
====================================...

Mesa Uranium Corp. (TSX-V: MZU) ("Mesa") and Energy Fuels are pleased to announce that the companies have signed a definitive agreement (following the Letter of Intent released in a June 5, 2007 news release) to form an exploration joint venture, West Lisbon JV, LLC ("West Lisbon"). The venture was formed to explore the DAR property in the Lisbon Valley Mining District of San Juan County, Utah. The northern boundary of the DAR property is located approximately two miles south of Energy Fuels' Energy Queen Mine which is currently being refurbished in preparation for production.

As previously released, the DAR property consists of 60 mining claims (approximately 1,240 acres) located one mile northwest of the North Alice Mine. The property is in a geologically similar environment and on trend with thick mineralization recently announced by Vane Minerals in a press release dated 11/16/2007. Vane's best intercepts ranged between 6.5 and 16.5 feet thick, and graded between 0.14 and 0.22% eU3O8.

Historic production from this district was reported in 1990 by the Utah Geological and Mineralogical Survey to be approximately 77,900,000 pounds of U3O8 between 1948 and 1977. Further, the U.S. Atomic Energy Commission reports production before 1967 from the North Alice Mine alone of 3,071,365 pounds of U3O8 at a grade of 0.275%.

The Joint Venture contemplates a 50-50 shared expenditure agreement to conduct exploration drilling on the DAR property. Previous exploration work in the 1980's by Energy Fuels Nuclear, Inc. identified strong uranium mineralization in several drill holes. Energy Fuels will be the operator of West Lisbon and will conduct the initial exploration work consisting of permitting and drilling. Should an economic uranium deposit be discovered on the claims held by West Lisbon, Energy Fuels will operate any mine that is developed.
