DIOS Hotish Butte Zone Returns Up to 0.23% U308 in Surface

MONTREAL, QUEBEC, CANADA--(Marketwire - Oct. 21, 2008) - DIOS EXPLORATION (TSX VENTURE:DOS) is happy to update its exploration progress on its wholly-owned Hotish uranium project in the Otish Basin, Quebec, Canada.

A reconnaissance program was completed to investigate seven selected geophysical targets on the extensive property. One of the first-priority geophysical targets, the Butte zone characterized by U/Th ratios of 2.1 times the background and extending a minimum of 2,5 km by 0,6 km was investigated in outcropping surface. Forty grab-samples were collected and nine (or 22.5%) assayed more than 0.06% U3O8, including 0.063, 0.064, 0.076, 0.076, 0.103, 0.105, 0.139, 0.225 and 0.23 % U3O8. Field readings (radiation solution RS-120) varying from 5,000 cps to 45, 000 cps (counts per seconds) characterize the Butte zone. The highest assays and counts are associated with biotite-rich samples.

A twelve-hole drilling program totalling 3,000 meters has just been completed on the same Butte zone over a 4km-strike length. Radioactive drill core is being processed at the Saskatchewan Research Council. Additional prospecting was also carried out on other targets and results are still pending. A major camp was built and DIOS is awaiting results and better weather to pursue the drilling campaign.

DIOS is in a good financial position and has the funds necessary (some 5.5 M$, non flow-through) to pursue its drilling programs in the years to come. This press release was prepared by M.-J. Girard, M.Sc. P.Geo., a qualified person pursuant to National Instrument 43-101. DIOS recently launched its new web site. www.diosexplo.com

The samples were collected and prepared by IOS Geoscientifiques Inc of Saguenay, Qc. They were assayed at the Saskatchewan Research Council.
