DIOS Lake Sediment Survey: Six Main Target Areas on Hotish Uranium Project, QC

MONTREAL, QUEBEC--(Marketwire - Oct. 1, 2007) - DIOS EXPLORATION INC. (TSX VENTURE:DOS) has received the results from its 2007 summer detailed lake bottom sediment sampling survey carried out by IOS Services Geoscientifiques Inc, its detailed helicopter-borne spectrometric survey carried out by Geodata Solutions Inc. as well as results from its first reconnaissance prospecting campaign for uranium exploration on the Hotish Property. The lake bottom sediment survey, which includes about 800 samples taken last June over the whole large 640 sq. kilometre Hotish property, defines clearly six (6) main uranium target areas. These significant anomalies coincide with broad spectrometric anomalies, and allows efficient ranking and narrowing of these anomalies.

These anomalous clusters of samples exhibit NE elongated shapes typical of the local glacial dispersal, suggestive of uranium-bearing boulder trains as sources. The cluster sizes vary from 1 km x 1 km to 11 km x 3 km with uranium values ranging up to 1,020 ppm U (parts per million). Such highly enriched samples are in sharp contrast with the 10 ppm U background of the area. This new larger scale survey confirms and better defines historical Uranerz data that included three significant uranium anomaly clusters (Tichegami-1, 2 and 4) reaching up to 147 ppm within parts of the Hotish property. Reconnaissance prospecting on former Uranerz anomalies yields up to 6,000 counts per second (cps) on granitic boulders. Three (3) new anomalous clusters were also outlined elsewhere on the property. The limited prospecting carried out last June allowed the discovery of a sandstone boulder grading 0,203% U308 within one of the new prospective areas. A prospecting crew just completed a second campaign and results are pending.

The Hotish property comprises three main blocks: the Hotish East block, directly adjacent to the Strateco property; the Hotish main block, located on the western shallow edge of the Otish sedimentary basin and directly west of the large Cameco property and the southern Papaskwasati block, located on the arch between the Otish Basin and the Papaskwasati sub-basin.

All lake sediments samples were analyzed by Neutron Activation (INAA) and Plasma Mass Spectrometry (ICP-MS) at Activation laboratory, Ancaster Ontario, while the rock samples were assayed by Saskatchewan Research Council from Saskatoon. DIOS has 33.9 million shares outstanding and an all cash working capital of $8.8 million. This press release was prepared by M.-J. Girard, M.Sc. P.Geo., a Qualified Person.
