DIOS Defines its 2011 Silver and Rare Earth Hotish Program

MONTREAL, QUEBEC, CANADA--(Marketwire - May 11, 2011) -DIOS EXPLORATION (TSX VENTURE:DOS) approved a significant exploration budget of some few hundreds of thousand dollars planned for this year on its wholly-owned silver and rare earths HOTISH PROPERTY.

Recent review by DIOS of IN HOUSE PROPRIETARY lake sediment surveys, soil surveys, rock sampling, geophysics and photo-interpretation for IOCG (iron oxide copper gold-uranium) confirmed its main 2011 Hotish targets:

1- Godzila high-grade uranium showing discovered only by walking over the outcropping rock (in place) and its southern extents associated with a 7 km by 1 km NE-SW cerium-uranium lake sediment anomaly;

2- A1 spectrometric anomaly associated with a well-defined NE-SW glacial dispersal train characterized by a 5-8 km by 2.5 km silver-cerium-yttrium-uranium lake sediment anomaly (natural state very anomalous lakes).

3- B2 spectrometric anomaly associated with a NE-SW glacial dispersal train characterized by a 12-15 km by 3 km uranium lake sediment anomaly (natural state very high content anomalous lakes).

4- A3 (south) spectrometric anomaly associated with a NE-SW glacial dispersal train characterized by a 10 km by 2 km yttrium-uranium lake sediment anomaly (natural state very anomalous lakes).

5- A2 (/Ring dyke) spectrometric (/magnetic) anomaly associated with a NE-SW glacial dispersal train characterized by a 8 km by 2 km lead-cerium-yttrium lake sediment anomaly.

Trenching and additional prospecting are planned on the high-priority targets. None has ever been tested by drilling. Two spectrometric anomalies from a 2010 government survey will also be prospected for the first time on DIOS newly staked claims on HOTISH NORTH. DIOS has around 3 M$ in working capital and 38.4 million shares and no warrants. This press release was prepared by M.-J. Girard, 43-101 QP.
