Geodex Minerals Ltd.: Sisson Brook's East Flank Continues to Show Encouraging Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 17, 2008) - Geodex Minerals Ltd. (the 'Company') (TSX VENTURE:GXM)(FRANKFURT:G2W) is pleased to provide assay results from five drill holes completed in the promising Central-East Flank area in Zone III of the Sisson Brook tungsten-molybdenum-copper project, located north of Fredericton, New Brunswick. These holes were part of the 2008 drilling program which ended in late August and comprised 11,819 metres in 48 holes.

The 2008 drilling program had two main objectives: 1) to further test the higher grade core of Zone III, including the East Flank; and, 2) to explore other promising targets on the property, in particular, the 'Ellipse' zone, adjacent to the south end of Zone III. (News Release, January 10, 2008).

Geodex released the results of the updated resource block model of Zone III molybdenum-tungsten deposit (based on 2007 and prior drilling results) in a Company News Release dated June 5, 2008. The new model shows a core area in Zone III with higher values in tungsten and molybdenum which would likely be the site of starter pits in the proposed mining development plan.

Drilling results to date indicate that this Central-East Flank core is an oval-shaped zone, approximately 600 metres by 300 metres in size and aligned in a northeast-southwest direction. The zone is open to the east-northeast and to depth. This area includes the high-grade 2007 molybdenum intersection in Hole SB-07-53: 0.305% Mo and 0.080% WO3 over 85.5m; (News Release, October 30, 2007).

In 2008, 14 holes for a total of 3,654 metres tested the Central-East Flank area. The results for the first five holes are highlighted below. The molybdenum values are particularly encouraging as they are generally significantly higher than those reported in Wardrop Engineering Ltd.'s 2007 Scoping Study and in the most recent resource estimate in June, 2008.

It is worth noting that SB-08-41 and SB-08-42 were drilled to the northeast - and thus at an angle to the east-west orientation of the other holes in Zone III. The intersections in both holes provide more evidence of the good continuity of the mineralization in the Zone III deposit.

A further 34 drill holes were completed in 2008 to test five other targets near the Zone III deposit. This drilling included the testing of known mineralized zones as well as other targets within the approximately nine square kilometre hydrothermal mineralizing system identified at Sisson Brook.

Other pre-feasibility development work is continuing at the Sisson Brook project. This includes mine planning and geotechnical studies overseen by Wardrop Engineering Ltd., an environmental and socio-economic program by Rescan Environmental Services Ltd. and metallurgical tests being carried out by SGS Labs in Vancouver. The samples used for the metallurgical testing have been collected from the Central - East Flank zone.
