DIOS Defines Good EM-VLF Drill Targets SW & South of Attila, at Southern Contact of Volcanic Dome With Dacite Flows

MONTREAL, June 17, 2021 - DIOS Exploration Inc. ("Dios") (TSX-V: DOS) is pleased to report good EM-VLF conductor drill targets were defined at southern contact of volcanic dome hosting Attila gold-copper-silver showing. This SW striking volcanic dome & dacite flow contact is 2.5 km long and a tuff horizon lies in its northeast extent.

To the southwest, where this prospective contact hits the Opinaca fault lies the most interesting VLF anomaly drill target, at least 500 m long, open to the east and located 120 north of a 3.17 g/t Au outcrop, north of Opinaca fault and major 5 km long sericite alteration corridor. Opinaca gold showing (previously up to 3.17 g/ Au) shows blue quartz eye sericite schists with 2-10% pyrite & chalcopyrite traces.

VLF anomalies could represent a contact shear zone or sulfides, good targets for gold-copper. Drilling is required due to marine clay cover. Hole 9 southward on Attila showing did not reach this contact area nor the VLF anomalies.

Two holes for 492 m were drilled on Attila, in fractured silica and sericite altered dacite with 1-7 percent quartz-chlorite-pyrite stringers with 1- 3% pyrite and chalcopyrite traces over 400 m x 500 m.

Southward (gold-copper-zinc soil anomalies), hole 9 cut dacite with numerous mineralized intervals (15 to 40 meters thick) ending in mineralized sericite diorite with 1-5% pyrite for last 13 m, open at 312 m. Best section of hole 9 is 6.3g/t Ag over 10 m with anomalous gold and copper (267-276m) including 25.8g/t Ag, 0.118g/t Au, 1.07%Cu (267-268m).

Northward, hole 10 hit similar dacite sequence with several mineralized intervals (22 to 46 meters thick) (0.90 g/t Ag, 0.060g/t Au, over 2 meters) also ending in chloritized and silicified diorite with 1-3% pyrite for last 7 m, still mineralized at 180 m.

M.J. Girard, President of Dios stated: "Attila prospect, located near crosscutting Kali fault, is a large chalcopyrite-rich stringer/stockwork, up to 8.08 g/t gold, 96.7 g/t silver, 2.43% copper, in a fractured rhyodacite dome overlying Kali Porphyry to the south. Assay data re-checks show gold is associated with chalcopyrite (copper). Drilling under the stringer/stockwork zone showed intense pyrite mineralization at depth, but less chalcopyrite. VMS systems usually show zoning in metal and mineral content. The Kali prospect 500 m north along Kali fault graded up to 8.28% copper, 40 g/t Ag and 2.6 g/t Au at Kali pluton contact. A big system occurs in this area. Follow-up work will focus on VLF-EM anomalies bordering the volcanic dome, on Kali prospect, on Opinaca zone, and prospecting a northern gabbro where volcanics returned 5.4 g/t Au."

The Sesame gold target, some 5 km north of Attila, is a two-kilometre-long, 200 metre to 400 m wide, northeast-striking airborne induced polarization anomaly, north of Kali pluton, and remains the number one drill target for the short term. (see June 1, release)
