MONTREAL, QUEBEC--(Marketwired - Aug. 10, 2017) - DIOS EXPLORATION (TSX VENTURE:DOS) is pleased to report summer campaign is in progress on large-scale K2 gold-silver-copper system, Lower Eastmain James Bay area, Quebec. Exploration program will target three main areas:

Attila gold-copper-silver showings area (see website for result maps)

Western (inputs/vtem) conductor area/target

Magnetic tilt target along the SW margin of Kali plug

a- The Attila showing in rhyodacitic flows that yielded 10 samples with values between 1 and 8.08 g/t gold associated with silver (1.5 to 96.7 g/t silver) and copper (0.12 to 2.40% copper) is composed of sulphides (chalcopyrite and pyrite) and quartz-carbonate-chlorite stockworks. It is also located in the vicinities of the NW Kali fault. Limited past work shows gold-in-soil anomalies (also copper-zinc) near Attila showings and Kali fault: DIOS will further prospect and extend soil sampling east and south, including over some untested VLF conductors.

b- At western limit of K2 project (6 km west of Attila), previous airborne geophysical surveys outlined a poorly outcropping two kilometer long (9 inputs & vtem anomalies) conductor at margin of Kali plug and adjacent felsic volcanics. No prospecting or follow-up are filed. Prospecting and reconnaissance (b-horizon) soil-sampling will be completed over poorly outcropping western conductor. Standard prospecting/mapping will also be carried out. Due to possible lack of rock outcrops, special attention will be put on glacial floats along conductor target.

c- Previous DIOS' field program confirmed spatial relationship between most of K2 gold-copper-silver sulphidic mineralization and the margin of a specific magnetic volcanic unit underlying a flattened rhyodacitic dome. Magnetic tilt suggests a similar favourable volcanic environment is extending west for 4 to 5 kilometers along Kali sub-volcanic intrusion. Follow-ups along this geophysical marker/target are in progress.

DIOS is looking forward to pursue exploration work on K2, Lower Eastmain near Opinaca Sub-province. Eleonore Gold Mine is in the Lower Eastmain near Opinaca sub-province. Technical content was prepared by H. Desbiens, M.Sc. Geo 43-101 QP.
