DIOS: 2000 Metre Drill Campaign on HEBERTO & a New Hydrothermal Magmatic Breccia Identified in Fold Nose Area 8 km More to the East

MONTRÉAL, QUÉBEC--(Marketwired - May 20, 2015) - DIOS EXPLORATION (TSX VENTURE:DOS) is pleased to report additional promising research results on Au33W property, hosting very prospective HEBERTO and ROBINO gold showing targets. Geophysical target prospecting for kimberlite by DIOS for diamonds in fold nose sector, some 8 km east of HEBERTO, helped discover breccia bearing many similarities with ROBINO hydrothermal magmatic breccia pipe.

DIOS is preparing a first 2000 m NQ diamond drilling campaign on HEBERTO gold target, a silicified quartz diorite returning 5.18 g/t gold over 5m in association with a 1.2 km long NS ground geophysical anomaly corresponding to disseminated fine grained pyrite to which gold is associated. A north-south striking 7 m wide mineralized envelope grading 1.89 g/t gold from all channel samples over the 10 m NS area that could be stripped is open along strike, at depth and to the west. Drilling will test this 1.2 km along extents and at depth. Some ten holes are planned as well as detailed prospecting of many other goldbearing dômes and breccia.

The large DIOS'wholly-owned AU33W property, James Bay, Quebec, is hosting a 8.5 by 5 km very prospective gold sector with several goldbearing magmatic dômes in association with hydrothermal alteration and related magmatic hydrothermal breccia and/or goldbearing quartz veinlet stockworks with disseminated fine grained pyrite. Intrusive dôme components vary from one another in this intense structural context. This news release was prepared by M.J. Girard, M.Sc. Geo, president, N1 43-101 Qualified Person.
