DIOS, Hotish Project: 7 Main Uranium Prospect And Drill Targets

MONTREAL, QUEBEC--(Marketwire - March 5, 2008) - DIOS EXPLORATION INC. (TSX VENTURE:DOS) targeted seven main areas for its 2008 Exploration Program on its wholly-owned Hotish uranium property in the western shallow end of the Otish Basin, Quebec, Canada. These areas were selected pursuant to specific proprietary geophysical (gammay-ray spectrometry, U/Th, K/Th & magnetic compilation), geological, structural, and detailed geochemical (lake sediments) criterias. The main target areas to be prospected and drilled are:


The area is characterized by a several kilometer long NE elongated radiometric anomaly and coincidental uranium lake sediment anomalies at its head along the Papawskasati River. The radiometric anomaly seems related to a boulder dispersal train. In its up-ice part, abundant NS structures intersecting NW structures are highlighted from magnetic data interpretation and gabbro dykes injected in the granitic basement may be good targets. About 10 km due south, one of the N-S gabbro yielded historical values up to 0.15% U308 over 1.8 meters in a drill hole outside the property. Some gabbroic and peridotitic sills have also been observed along an ENE structural corridor (well-defined magnetic Hippocampe-Takwa greenstone-belts) in the vicinities of the lake sediment anomalies.

Further to the southwest, nearby the Yvon uranium showing (360 ppm U), extents of the NE (graben-type) structures limiting the sedimentary basin are coincidental with strong uranium lake sediment anomalies and represent another first-priority target.


The area is characterized by a several kilometre long NE radiometric anomaly (probably a boulder dispersal train) that stops right at the former Uranerz TICH-4 lake sediment anomaly. The geological setting is composed of the unconformity contact between the Otish basin and the granitic basement. Magnetic data shows N-S structures (gabbros?), crosscutting the unconformity. So both Matoush and/or classic unconformity types targets may explain the uranium anomalies in this area. Just west of it, another NE unexplained radiometric dispersal train seems to stop on its up-ice side just at a north-south magnetic feature (gabbro).


The area is characterized by a kilometric NNE radiometric anomaly coincidental with abundant quartzite (and minor peridotitic) boulder dispersal trains. Its up-ice part it is coincidental with the contact of the Otish basin with the granitic basement (unconformity-type) just west of the Cameco property.


The area is underlain by granitic basement associated with topographic highs hosting former Uranerz lake sediment TICH-1 &2 anomalies. Both anomalies are E-W striking with TICH-4. A lone NNW gabbroic dyke is known west of TICH-1. A Matoush-type target is looked for in this environment.

5-MANTOUCHICHE-WEST TARGETS: The best radiometric anomaly on the property is east-west striking with Majescor Mantouchiche uranium showing that yielded 0.20% U308 over 4,50 meters in fractured pegmatite intruded by a gabbro and more recently an intercept of 0.20%U3O8 over 17 m. The geophysical anomaly is coincidental with an east-west magnetic feature and granite high topography. In the Mantouchiche Lake area, several Proterozoic sediment windows have been preserved. The latter are probably associated with favourable NE graben-structures that warrant investigation.

6-F2 ANOMALY TARGET: A first-priority radiometric anomaly extending itself over 1,2 km x 0,3 km shows the same NNE orientation as the one observed on the nearby Strateco Matoush project located just south of this block.

7-MEMESHQUASATI GREENSTONE BELT TARGET: The non-prospected mafic rocks represent a nice structural/chemical trap (Matoush-type) such as the Hippocampe-Takwa greenstone-belt more to the south.

On each of the selected target areas, DIOS plans follow-up prospecting, mapping, geochemical sampling and geophysical (magnetic/VLF-EM and ground spectrometer) surveying as a First Phase Program. A Second Phase program consisting of test-drilling the best targets is also planned in 2008.

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 34 million shares issued and outstanding and a non-flow through working capital position around 8 millions dollars. This press release was prepared by M.-J. Girard, M.Sc. P.Geo., a qualified person pursuant to National Instrument 43-101.
