MONTREAL, QUEBEC, CANADA – DIOS EXPLORATION reports significant exploration progress on its wholly-owned Hotish uranium project, Otish Basin, QC.

A wholly new area is discovered, showing interesting results: rocks return up to 0.169 uranium oxide (U3O8), 182 grams per ton silver (g/T Ag) and 1.9 % copper (Cu). Last fall, a prospecting program investigated selected geophysical targets on the extensive property and on one of these, eight samples were taken including five grab-samples from amphibolite rock boulders containing 1-2% pyrite and traces of chalcopyrite-malachite. Four samples return the following assays respectively:

0.169, 0.129, 0.126, 0.058 % U308 1.90, 0.448, 0.0693, 0.0532 % Cu 182, - - 3 Ag (g/T) 112, - - 3 Au (ppb)

Mafic or ultramafic rocks are considered good chemical traps for uranium. A review of all geophysical data of this area is in progress and additional mapping and prospecting is planned for this summer, as well as significant follow-up work (including prospecting, detailed electromagnetic and soil geochemistry surveys) on other targets.

One hole completed on Hotish`s BUTTE zone last Fall over a major spectrometric anomaly covering a 4 km-strike length had returned a 10.9 meters interval assaying 13.7g/t Ag; 1.20% Pb; 0.60% Zn within a 60 meters-wide zone with 3-10% disseminated sulfides within paragneiss that yielded 5.2g/t Ag; 0.26%Pb; 0.19% Zn. That drilling campaign had enabled the discovery of the first BUTTE zone at depth, a sub-vertical uranium-bearing zone reaching at least 240 m vertically from the surface and intercepted by three holes in two sections 60 m apart along strike, with a rather true width of 3.5 m returning 0.093% U3O8 (incl. in 0.04 % U3O8 over 12.5 m), 0.056% U3O8 over 5.1 m and 0.083% U3O8 over 2.6 m.
