Gold project AU33 WEST: surface work results

Dios Exploration and its  partner Osisko proceeded this fall with surface work on the AU33 West gold project (see October 24, 2012 post).

Dios Exploration recently reported good news after first assay results.

 Ten trenches were dug up to test soil geochemical targets or to extend known gold mineralized occurrences.

The best results come from the Héberto occurrence, in a mylonityzed tonalite, a granite type. The results returned grades as follows :

  • 5.0 grams per ton in gold over  5.25 m
  • 1.12 grams per ton in gold over  4.5 m

It is important to note that analysis within the tonalite was realized withinan homogeneous rock and not in veins (eg. Quartz). This could suggest interesting gold mineralization tonnage.

Other anomalous results from 0.5 to 1.1 g/t in gold on brackets of 0.75 to 2.25 m were as well obtained on other trenches.

These trenches allowed a good exposure of the mineralized occurrences and a better understanding of the vectors in place controlling the mineralization.


Remember that Osisko is a major partner who can acquire 51% of the AU33 WEST property. This partner has to incur  5,000,000 $ in exploration and  700,000 $as payments over 5 years.

The work previously mentioned is part of this partnership and is funded 100% by Osisko

Later on, if Osisko desires, an additonnal participation of 9 % is possible with further work of 9,000,000 $ over  5 years. Another 10 % is as well available with the financing of a feasibility study.

Osisko is a worldwide mining corporation based in Montreal for aquisition, exploration, developpement, and exploitation of auriferous properties.

AU 33 WEST Gold Project: Surface Trenching Work with Backhoe

Dios Exploration announced on September 24th, that two backhoes were moved this Fall on AU 33 WEST Gold Project.

This is major work for this project.

The trenching work is taking place this fall. Detailed rock sampling was undertaken and rocks to be assayed. The results will soon be published…

Why all this agitation? Because Dios Exploration :

  1. Thinks of AU33 West in James Bay as its project with the best mining potential
  2. Joint ventured with a major company, Osisko, to fund total expenses over a 5 year period. The partnership is renewable for another 5 year period afterwards.
  3. Considers that all main factors are in place to discover an economical mining deposit easily exploitable: surface exploitation and road infrastructures in proximity, the Eastmain 1 Hydro Power Complex road.

The best summer 2012 sampling results of rock outcrops and soils sustain such enthusiasm:

G/t gold


17.3 Granodiorite, fine grained, beige, rusty, 2% pyrite, quartz vein of 4 cm
12.6  Granodiorite, fine grained, beige, rusty, 3% pyrite, magnetite
11.8 Tonalite, fine grained, strongly oxidized, quartz veinlet network, disseminated pyrite mainly in quartz veinlets
4.7 Granodiorite, medium grained, beige, magnetic, rusty in places
1.7 Granodiorite  with pegmatite, aplite and felsic dikes, quartz-hematite veinlets with  traces pyrite

Please note that this geological model bears a lot of similarities with that of the Malartic mine , operated by Osisko, with a gold grade of 1 g/t.

Geographically, the project is located a few hundred kilometers north north-east of Matagami. Geologically, it is located in the Opinaca Eastmain emerging gold camp , some 60 km away from the world class Eleonore  gold deposit developed by Goldcorp.
