DIOS' Spectrometry Survey Outlines Nine First-Priority Uranium Zones on Hotish

MONTREAL, QUEBEC--(Marketwire - Oct. 30, 2007) - DIOS EXPLORATION INC. (TSX VENTURE:DOS) has received the final interpretation and processing report of its 2007 helicopter-borne gamma-ray spectrometry survey over its Hotish uranium property in the Otish Basin, Quebec, Canada. That survey processing outlined nine first-priority uranium targets including many coincidental with significant uranium lake sediment anomalies. Three first-priority targets have been delineated on the Hotish East block, adjacent to the Strateco property.

Last summer, Geo Data Solutions inc ("GDS") of Laval completed a large gammay-ray spectrometry survey totaling 7,539 line-km over 6 blocks, of which 6,342 line-km were flown with a 100 m line-spacing and 1,197 line-km with a 200 m line-spacing. Independant geophysical consultant Camille St-Hilaire defined thirteen priority uranium targets including 9 first-priority, 2 second-priority and 2 third-priority targets. The targets are characterized by very high Uranium/Thorium ratios and low thorium and potassium contents in association with structural features.

The most significant ("C1") target is a linear, east-west striking, 2,5 km by 600-750 m large geophysical anomaly showing 6 times the U/Th background ratio. Other significant ("A3" and "A2") targets extending respectively over 2,500 by 2,000 m and 2,000 by 2,000 m fit perfectly over lake sediment uranium anomalies and show an association with magnetic features. They might correspond to the same and only anomaly cut through by a NE-oriented structure. The A 2 and A 3 targets are located up-ice of the metric size uranium bearing sandstone boulder discovered this summer by DIOS.

The Hotish property comprises three main blocks: the Hotish East block, adjacent to the Strateco property; the Hotish main block, located on the western shallow edge of the Otish sedimentary basin, located directly west of a large Cameco property; and the southern Papaskwasati block, located at the northeastern end of the Papaskwasati sub-basin and over the Mantouchiche Arch, once linking the two sedimentary basins.

DIOS has 33.9 millions shares issued and outstanding and a non-flow through working capital around 8.5 millions dollars. This press release was prepared by M.-J. Girard, M.Sc. P.Geo., a qualified person pursuant to National Instrument 43-101.
