Tribune Uranium and Fission Energy Joint Venture Initiates Athabasca North Shore Exploration Program

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 17, 2007) - Tribune Uranium Corp. (the "Company") (TSX VENTURE:TCB)(FRANKFURT:S8QA) and Fission Energy Corp. (TSX VENTURE:FIS) ("Fission") are pleased to announce that they have initiated a Joint Venture program at their North Shore Property, located immediately north of Lake Athabasca, in northeastern Alberta. The Joint Venture program will include additional geological mapping, geochemical sampling and geophysical surveys. A targeted airborne radiometric survey and a drill program designed to test priority targets, established during the 2006/2007 exploration program, will be mobilized during this quarter. Fission Energy Corp. is the operator of the program which will continue into early 2008.

Tribune Uranium Corp. has the option to earn a 60% interest in the North Shore Property from Fission Energy Corp. by making certain cash payments, and expending $10 million on exploration over 5-years.

The North Shore Property comprises 113,250 hectares (approximately 280,000 acres) along the northwestern margin of the Athabasca Basin. It is located approximately 10 kilometers west of the Maurice Bay uranium deposit owned by Cameco Corp. At Maurice Bay, uranium mineralization is reported to be structurally controlled within basement rocks and at the sub-Athabasca unconformity.

Historic exploration at the North Shore Property, which included ground and airborne geophysics, prospecting, geologic mapping, and drill testing of lithogechemical anomalies and alteration zones, identified over 200 uranium occurrences and showings. The property has potential for unconformity, sub-unconformity and Beaverlodge-type mineralization.

In late 2006, Terraquest Ltd. completed an 8,040 line-km Magnetics - VLF survey over the property. The survey was undertaken to identify possible basement structures and potential new areas of interest for uranium exploration. The following areas of interest have been targeted for the current exploration program.

1) Greywillow Point/Fallingsand Point are located immediately southwest of the Maurice Bay Uranium Deposit. A significant portion of the area is interpreted to be underlain by near-surface (less than 50 m) thicknesses of promising Athabasca Basin stratigraphy. Historic exploration completed by Uranerz during the 1970s and 1980s included nearly 200 drill holes within an area measuring 9 by 1.5 km, as follow-up to approximately 200 boulders that assayed between 0.006 to 0.95% U3O8. The drilling intersected significant alteration, but failed to identify the source of the uranium. More recently, approximately 4 kilometers to the NW of this location, Fission discovered a boulder that assayed 1.39% U3O8 during the 2006 prospecting program conducted on the property. The subsequent 2006/7 airborne survey identified numerous magnetic discontinuities and XDS-VLF data are suggestive of faults that warrant follow-up exploration.

2) Fiddler Point is located immediately north of Lake Athabasca. The area is underlain by basement gneisses and intrusive rocks and the terrain exhibits significant erosion. The exploration targets in the area are sub-unconformity style uranium mineralization. The 2006/7 airborne survey identified several magnetic discontinuities and XDS-VLF data interpretations are indicative of faults in the area. In addition, prior exploration identified numerous radiometric anomalies that ranged from 1,000 to 10,000 cps, and uranium occurrences in outcrop that ranged from 0.01 to 0.058% U3O8.

3) Area A is located to the northeast of Fort Chipewyan. It is underlain by sheared and faulted basement gneisses proximal to the regional Charles Lake Shear Zone. Exploration by Fission during 2006 identified a zone of basement hosted uranium mineralization, which comprises a zone of intense brecciation and alteration up to 20 m across with a strike length exceeding 100m. The anomalous zone runs parallel to sub-parallel with a major fault structure trending through the region. The lithology underlying Area A is granitic to gneissic / brecciated gneiss consisting of plagioclase pegmatites, granites and monzonites. Dirty quartzite is also found. Graphite and pitchblende are observed in varying amounts from trace to several percent. Intense hematite alteration exists throughout most of the zone with occurrences of autunite common. Surface radiometric surveys returned up to 13,000 cps and uranium values up to 0.521% U3O8. During 2006/7 surface mapping / prospecting, a Max-Min Geophysical Survey and an IP Resistivity Survey were completed.
