Dios Exploration Inc./UPINOR 2008 Radiometry Extends Main Uranium Zone and Outlines Several New Ones

MONTREAL, QUEBEC--(Marketwire - Sept. 18, 2008) - DIOS EXPLORATION INC.(TSX VENTURE:DOS) reports that its 2008 Radiometric Survey on UPINOR extends the main uranium zone discovered in the Fall of 2007 and outlines several new radioactive zones. That survey processing outlined eleven first-priority kilometric size uranium zones including many coincidental with uranium lake sediment anomalies. DIOS effectively received the final interpretation and processing report of its 2008 helicopter-borne gamma-ray spectrometry and magnetic survey over its UPINOR uranium property in the LaGuiche Basin, Quebec, Canada.

This summer, Geo Data Solutions of Laval, Quebec, completed a 3,711 km-line low-altitude (40 meters) spectrometry and magnetic survey flown with a 100 m line-spacing. Independent geophysical consultant Camille St-Hilaire defined seven first-priority uranium zones with good Uranium/Thorium ratios in association with structural features on the northern part of the UPINOR property.

The most significant ("A") zone is a linear, east-west striking, over 10,0 km long by 0,2-0,5 km large geophysical anomaly showing 2,4-3,2 times the U/Th background ratio. The A zone, discovered last fall, is coincidental with an outcropping stratabound unit characterized by continuous radioactive high counts per seconds (cps) in the order of several thousands cps up to 36,000 cps over at least 5 km in strike in the field (and 600 m in thickness). It consists of several radioactive sub-horizontal dykes (sills), one reaching some ten meters within metamorphic rocks (gneiss-metasediments). The 2007 Fall reconnaissance sampling program returned up to 2% uranium oxide (U3O8) including 5 samples greater than 0.2% U3O8, and 10 samples with grades higher than 0.1% U3O8. A Rossing-type (8% of the world production) large volume uranium model is considered in association with numerous anatexis-granites occurring within the LaGuiche paragneisses. A reconnaissance program is already planned to investigate the most significant radiometric anomalies this Fall.

The new "G" zone appears as the western extent of the A zone. This linear anomalous zone extends for a minimum of 5,0 km in strike length with U/Th ratios between 1.8 and 2.6. The east-west A-G zones axis is folded and its southern extent seems thinner (4 km long D zone with a U/Th equals 2.2). Other significant ("B", "C", "E" and "F") more isolated zones extend respectively 1,0-2,0 by 0,5-1,0 km and have U/Th ratios between 2,1 and 2,7.

On the not yet explored southern claim block of the Upinor property, C. St-Hilaire outlined four other kilometric size uranium zones with U/Th ratios between 1.6 and 3.0. Most of them appear wrapped around a magnetic mafic intrusive.

During summer 2008, DIOS and Sirios Resources completed a twelve-hole helicopter-borne drilling program totaling some 1,300 meters on the A zone. The core samples are still being processed at Saskatchewan Research Council Laboratory.

The UPINOR uranium property comprises 780 map-designated mining cells covering 400 square km. It is located about 20-30 kilometers north of the Opinaca Nord uranium project and about 50 km south of the all-weather Trans-Taiga road, James Bay, Quebec. It is rather easily accessible, a significant criteria for a uranium deposit. The UPINOR project is held by DIOS in a 50-50 partnership with Sirios, and DIOS is the operator. Fieldwork was completed by IOS Geoscientifiques on the targets delineated by the DIOS' geologists. The DIOS' team is of the opinion it has uncovered a new uranium district in Quebec, with all its new uranium discoveries in the Opinaca area.

DIOS is in a good financial position and has the funds necessary to pursue its exploration programs. This press release was prepared by M.-J. Girard, M.Sc. P.Geo., a qualified person pursuant to National Instrument 43-101.
