Tribune Minerals Updates North Shore Uranium Project, Athabasca Basin

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 13, 2008) - Tribune Minerals Corp. (TSX VENTURE:TCB)(FRANKFURT:S8QA) ("Tribune") (the "Company") and joint venture partner Fission Energy Corp. (TSX VENTURE:FIS) are pleased to provide an update of exploration activities at the North Shore Uranium Project in northeast Alberta. The North Shore Property comprises 113,250 hectares (approximately 280,000 acres) along the northwest margin of the Athabasca Basin, approximately 10 kilometers southwest of Cameco's Maurice Bay Uranium Deposit (1.3 million lbs @ 0.6% U3O8). Tribune has the option to earn a 60% interest in the project by expending C$10 million in exploration over five years. Fission Energy Corp. is the operator of the North Shore Property exploration program.

The 2007/8 exploration program began last winter with a 696 line-km, 200 m and 100 m line spacing airborne high resolution magnetic and electromagnetic (VTEM) survey in the northeast part of the property, and concluded with a seven hole spring drill program totaling 1,260 m. Drilling targeted areas of postulated structural and hydrothermal alteration, as observed in historic drilling and interpreted from recent geophysical surveys (See press release dated March 25, 2008).

The exploration program successfully identified a significant hydrothermal system associated with a major northeast trending structure. Strong alteration and radioactivity were intersected along this structure at downhole depths up to 185 m, with widths ranging from less than one meter to 8.5 meters. The basement hosted altered zones contained highly anomalous concentrations of geochemical pathfinders, and included uranium values ranging as high as 70.5 ppm U. These results are very encouraging at this early stage of exploration.

A total of seven (7) BTW diameter core holes were completed between March and May, 2008. Each hole was surveyed for radioactivity with a Mount Sopris 2PGA-1000 poly-gamma downhole probe, with the exception of NS08-005, which was not probed due to probe mechanical issues. All drill core was geologically logged and systematically sampled for geochemical and clay analysis. One-half of the core was split and sent to SRC Analytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis, which included a 63 element ICP-OES, with uranium by fluorimetry (partial digestion) and boron. The geochemical analysis is presented in Table 1.

Four holes (DDH: NS08-002, 003, 004 and 007) encountered geochemically anomalous intervals ranging in width from 0.5 m to 8.5 m with uranium values as high as 70.5 ppm in (NS08-004), associated copper values (to 984 ppm Cu in NS08-007), and occasionally anomalous zinc (to 216 ppm Zn in NS08-003). Hole NS08-007 returned copper values of 305 ppm over 3.5 m from 38.0 to 41.5 m.

These four drill holes tested an area of alteration discovered by historic shallow drilling directly adjacent to an area of relatively high conductivity identified by the VTEM survey. Holes NS08-002, 003 and 004 intersected intervals of significant structural and hydrothermal alteration, and encountered mineralization greater than 10 ppm U over drill hole widths of 0.5 to several meters within basement rocks. Holes 003 and 004, spaced 1.2 km apart, intersected strong pervasive alteration and intermittent mineralization between 72 to 99 m depth. Hole NS08-007, located 850 m northeast of NS08-004 along an inferred structure, contained significant intermittent copper anomalies between 70 and 79 m (up to 984 ppm Cu), which corresponds with other anomalous geochemistry and radioactivity observed within NS08-002, 003 and 004. The correlation between anomalous uranium and pathfinder geochemistry in NS08-002, 003, 004 and 007 has outlined a large, hydrothermal system favorable for uranium mobilization and mineralization. This region continues to be of primary interest.

The drill program was successful in testing for alteration and potential mineralization at depths that exceeded previous historic drilling. Further exploration planning is underway. Final geophysical interpretation of the airborne data will be integrated with the current drill results, to refine locations for future exploration.
