Drilling campaign planned on large-scale AU33 gold project targeting fold nose 8.5 km east of Heberto gold discovery

August 30, 2017

DIOS EXPLORATION is pleased to report drilling campaign planning is in progress on large-scale AU33 gold project, James Bay Eeyou Istchee, Quebec.  Exploration drilling will also focus on fold nose target, a folded mineralized and magnetic tonalite sill horizon with quartz stringers, jammed in folded volcanic horizons, 8.5 km east of Heberto gold discovery.


This folded horizon drilling target is located up-ice of a group of strong gold-in-till anomalies and the Chain Lake structure goes straight through the fold nose hinge.  Structures and fold nose hinges help to concentrate gold and are good places to look for gold enrichment and a gold deposit.


DIOS’ personnel recently prospected two circular low-mag anomaly targets within a magnetic diorite in the fold nose area. The area is poorly outcropping, covered by till drumlins. A 10 x10 m angular glacial boulder field was sampled (3 grabs). It is dominantly composed of angular metric boulders (proximal source) of magnetic tonalite injected by 3-5% cm quartz stringers and hosting 0.5-3% disseminated pyrite. This specific marker horizon was previously mapped up-ice (highest assay 0.8 g/t gold) in the northern flank of the fold and has a good magnetic signature.  DIOS is targeting gold enrichment in the folded part of the horizon


Heberto Gold is located in the middle of the significant gold glacial train whereas this fold nose target area is at the head of the gold train, suggesting a major gold source.


The AU33 project hosts a regional east-west striking deep structure (Chain Lake Break) along which numerous significant gold occurrences such as Eastmain Clearwater deposit and Osisko Mustang-Wabamisk gold systems are present.  Along this favourable break, an area with complex cross-cutting subsidiary structures was targeted and Heberto Gold gold was thus discovered as well as other gold showings.


The CLN (Chain Lake North) gold showing, 2 km north of Heberto, was revisited recently by DIOS. Previous CLN sampling yielded values from 2 to 12.65 g/t gold. Nine grab-samples were just taken along a 75 meter strike of the mineralized altered structure. Mineralization is typically a 5-15 m wide foliated altered (biotite-rich/quartz-pyrite/potassic feldspar bands) zone within tonalitic rocks. Pyrite contents in foliated zone vary from 1 to 10 %, averaging 2-5 %. It is quite similar to the Heberto gold zone, but steeper. The CLN zone is bordered to the north by hematized epidotized magnetic tonalite.  This is another very good drilling target.


 In addition to Heberto Gold discovery, where 3-D studies are in progress to further delineate drilling targets, DIOS is looking forward to pursue exploration work on other AU33 gold targets.

Several tens of meter mineralized zones in DIOS’ first holes of winter drilling program on Heberto Gold

DIOS EXPLORATION is pleased to report first 3 holes (some 1100 m) of ongoing drilling on wholly-owned Heberto gold project, intersected several tens of meters of mineralized zones, more at depth than 2 previous 2015 and 2016 drilling campaigns.


Mineralized zones show strong hydrothermal alteration in sheared rocks with biotite, silica and microcline and fine pyrite and magnetite. Gold content is directly related to these minerals. Several hundreds of core samples were sent for gold assaying this week. Hole 17 was even deepened for 200 m and the Heberto gold zone was again hit at depth.

Drill 2

The Heberto Gold discovery had yielded 4.8 grams gold per tonne over 8.65 meters last year in 2.13 g/t Au /22.90 m; 2 g/t Au over 22 m some 75 m deeper and 1.8 g/t Au /18.45 m some 75-100 m even deeper and 3.65 g/t Au/13 m some 50 m to the south in 1.15 g/t Au/64 m.

The Heberto gold zone discovery (no royalties) is located 50 km south of Goldcorp’s Eleonore gold mine, Eeyou Istchee James Bay, Quebec, and 20 km west of Clearwater gold deposit. DIOS’ property is adjacent to EM 1-A power plant.
