UPDATE ON WEST AU33 GOLD PROJECT
MONTREAL, QUEBEC, CANADA - DIOS EXPLORATION updates its wholly-owned WEST AU33 gold project a few hundreds of km north-north-east of Matagami, QC.  Planned work is to test a dome-like magnetic structure near the Heberto showing, a first priority target that returned 5.0 g/t gold (grams per tonne) over 5.25 m et 1.12 g/t gold over 4.5 m in a sheared tonalite (type of granite).  Interesting induced polarization anomaly data will be detailed studied and checked in the field, as well as good drilling targets near the Heberto showing.  Several anomalous results of 0.5 to 1.1 g/t gold over 0.75 to 2.25 m were also returned in other trenches.  Half of planned trenches and stripping have not yet been dug.  Field work will target the fold nose area and some diorite granite geological contact, as well as a breccia zone target in contact with a diorite.  Known gold showings discovered to date do not explain in all its length the gold glacial dispersal train with several values greater than 1 g/t gold in till, one of the most significant gold glacial dispersal train in the Opinaca area.
DIOS was advised that recent major cuts and lay-off of Osisko exploration personnel will not allow for the option agreement to be pursued in 2014.  An investment of some $ 1.4-1.5 million was incurred by the partner over the last two years.
DIOS would like to acknowledge the exploration geologists of Osisko for their positive contribution.  DIOS discovered in 2009 and 2010 major gold anomalies in till while sampling for diamond indicators near major structures across a large granite and  granodiorite covered area; gold-bearing metric angular tonalite boulders were then discovered.  Osisko funded the exploration programs since 2011: mapping and prospecting surveys, soil geochemical surveys (humus – B horizon) mainly in the central area near the auriferous glacial boulders and discovered several outcropping gold showings,  including Heberto (5 g/t gold over 5.25 m), composed of 1-3% pyrite, finely disseminated in lightly sericitised foliated tonalite.  This mineralized occurrence is associated to a weak 1.4 km long induced polarization anomaly and remains open in all directions. Large stripping and drilling was planned by the exploration team.

Mineralization (disseminated, not vein-hosted) and metal associations suggest potential for a low-grade bulk tonnage gold deposit (oxidized intrusion related).  The occurrence of concentric structures associated with mineralized brittle structures, the major regional gold in till anomalies, the highly anomalous gold background of the fractured intrusive suggest that this property still hosts a potential for a worldclass five million ounces gold deposit or more, particularly in the central part near  Heberto and more to the east in the fold nose very poorly outcropping area.  Certain geochemical features similar to Malartic were also observed.  This release was prepared by M.J. Girard, M.Sc. Geo, a 43-101 Qualified Person.
