Drilling Program in Progress on Pontax: 20 Kimberlite Targets to Be Tested by DIOS

MONTREAL, QUEBEC--(Marketwire - Dec. 12, 2007) - A 2,000 meter drilling program was initiated on the Pontax project, and about 20 first-priority geophysical targets are to be tested for kimberlite potential by DIOS EXPLORATION (TSX VENTURE:DOS). These targets were selected from 66 kimberlite magnetic anomalies outlined by a 3,200 line kilometer helicopter-borne low altitude geophysical survey. Previous DIOS glacial sediment (till) sampling programs identified quality kimberlite indicator minerals such as harzburgitic garnet (G10), and omphacite, a mineral of great significance due to its eclogitic origin, thus suggestive of very high diamond potential content. The drilling targets are located up-ice of dispersal trains including G10 pyrope, omphacite, picroilmenite, kosmochlor (clinopyroxene) and forsterite (olivine). Regional seismic tomography indicates that the Pontax area is underlain by a very thick (and cool) crust, favourable for diamond preservation. The present drilling program will be extended into the New Year.

DIOS has the rights on 100 % of all diamonds from the Pontax property (1,436 claims totaling 760 sq. kilometres), after pay back of exploration expenditures and costs incurred by partner Sirios Resources Inc. and relevant to a diamond discovery. Sirios would keep a 1 % royalty, redeemable for one million dollars. The Pontax property is located in the James Bay area, Quebec, 350 kilometers north of the town of Matagami along the paved road going to Radisson. It is also located approximately 75 kilometers southwest of the ELEONORE gold deposit bought by Goldcorp and adjacent to the northeast of the extensive De Beers-Majescor Mirabelli property.

With only some 34,000,000 shares issued, DIOS is in a very good financial position and would offer a high leverage with a new kimberlite discovery. DIOS, a leader in diamond exploration in Quebec, has some 3,000 sq. kilometres of mining rights.
