DIOS' Hotish Property Update and Uranium Potential

MONTREAL, CANADA--(CCNMatthews - May 25, 2006) - The HOTISH PROPERTY of DIOS EXPLORATION INC. (TSX VENTURE:DOS) is a large mining property covering the western edge unconformity contact of the Otish Sedimentary Basin. The area is well-known for its uranium potential. The Otish Mountains were recently the focus of intense activity by mining giant Cameco Corporation, the world's largest uranium producer, whose claims border DIOS 's HOTISH property to the EAST. The HOTISH PROPERTY of DIOS is also directly adjacent to the north to the Beaver Lake property where an historical data occurrence of 145,000 tonnes grading 0.11 % U3O8 is reported with chosen samples grading from 0.23 to 2.46 % U3O8.

The HOTISH PROPERTY of DIOS is wholly-owned by DIOS without any encumbrances. Also, it now includes a large claim block covering the extent of the unconformity contact, directly adjacent to the STRATECO Property, where a high grade uranium intercept of 9.5 metres grading 1.54% U3O8 was drilled recently along with four other holes in the uranium-bearing structure discovered in 1984 by Uranerz Exploration and Mining, before uranium prices tumbled in the mid-eighties. This Uranerz hole returned a 16-metre intercept grading 0.95%U3O8 per tonne (19 lbs per ton) at a vertical depth of 220 metres.

Marie-Jose Girard, C.E.O. of DIOS, worked for many years as a professional geologist for uranium exploration in the seventies in the Otish Sedimentary Basin. The sharp increase in U3O8 prices as well as the world demand for uranium as an energy alternative certainly enhances the uranium potential of the Hotish property of DIOS covering a large part of the Proterozoic unconformity contact over an Archean age basement, a classical geological context known worldwide for major uranium deposits.

DIOS is a significant diamond explorer focused in Central Quebec where it owns one of the largest strategic mining rights holding for this commodity.
