DIOS fore les anomalies de sols de WTS et frappe des valeurs en or très intéressantes dans ce secteur vierge du projet AU33, atteignant 18 g/t en or sur 1 m

Montréal (Québec) –DIOS EXPLORATION publie les résultats significatifs des forages de la cible WTS sur sa propriété AU33, atteigant 18 g/t Au sur 1 m (6.08 g/t Au / 3 m) et 4.41 g/t en or sur 1 m dans un autre sondage à 100 m de distance. DIOS a fore dix sondages exploratoires de 100-150 m de longueur, souvent distants de 200 m, en amont glaciaire de valeurs élevées en or dans le till glaciaire: voir tableau et carte.

L’horizon magnétique WTS affleure peu mais des sols analysés en 2018-2019 ont mené à la découverte d’essaims anomaux en or (8 à 269 ppb Au) près de 2 structures démagnétisées recoupant l’horizon magnétique WTS de 300-350 m de large. Aucun affleurement aurifère n’y a été découvert, à 8 km au NE des zones aurifères d’HEBERTO.

De nombreuses structures aurifères étroites (1- m) donnant de 0.5 à18 g/t Au) associées à des veinules centimétriques de quartz (pyrite-chalcopyrite) et/ou à de la pyrite disséminée (1-4%) ont été rcoupée par les forages de fin 2019 près des anomalies en or dans les sols de WTS.

ROBINO (in English)
Gold mineralization associated with Robino breccia is controlled by NNW to NS structures, including fractures, quartz stringers/veinlets, and shear zones, recalling geological context of Heberto. Channel sampling across breccia indicates that clasts are barren and mineralization occurs in altered breccia matrix. Mineralized breccias are often associated with intense hydrothermal activity in cupolas and apophysis above porphyry intrusions. Source of gold could be located in root zone of Robino breccia or could have migrated in nearby structure. This also suggests possible occurrence of magmatic-hydrothermal breccias near Heberto showing 3.5 km to the south.

Flat tension high-grade quartz-pyrite veins (up to 94 g/t gold) associated with foliated eastern margin of NNW Robino breccia are reminiscent of flat quartz-pyrite-magnetite veins associated with NNW shears observed at Heberto. They were observed on a surface of 2-3m x 20m along a N-S foliated basic dyke, but not in hole 39, though two one-meter long channel samples had returned 5 g/t Au / 1 m each.

Hole 40 tested a NE chargeable induced polarization anomaly adjacent to Robino breccia. It intercepted fractured tonalite with 1-2%pyrite between 53-85m and sericitic magmatic-hydrothermal Robino breccia with 2-3% disseminated pyrite between 85-155 m (0.01g/t Au) . Robino breccia is locally injected by minor metric feldspar-phyric diorite dykes with 2-4% pyrite. An adjacent sericitic foliated/fractured zone with 1%pyrite assayed 2.26 g/t Au over 1 m (0.404 g/t gold over 6 m).

Hole 40A tested SW extension of Robino breccia. It intersected fractured tonalite with 1-2% pyrite between 85-160m and sericitic magmatic-hydrothermal Robino breccia with 1-2% disseminated pyrite between 160-269 m (0.015g/t Au). Robino breccia is injected by numerous metric feldspar-phyric diorite dykes with 2-4% pyrite. These are known as favorable gold metallotect in the region. An adjacent sericitic-albite fractured zone with 1-2% pyrite yielded 0.077g/t Au/7.5m (287-294.5m). This hole confirms N230 strike, dip 25-35 degree to the SW of the Robino breccia.

Hole 42 tried to test the N290/30 Robino breccia and adjacent circular low magnetic & resistive anomaly. It intersected poorly fractured tonalite with pyrite traces between 160-303m and sericitic magmatic-hydrothermal Robino breccia with 1% disseminated pyrite between 303-310m (0.061g/t Au) at the bottom. This hole was stopped due to bad ground conditions. Robino breccia is usually injected by metric feldspar-phyric diorite dykes with 2-4% pyrite, so this hole did not reach it.

Similarities of Robino geochemistry with Heberto diorite suggest they may both represent apophysis of deep gold-bearing intrusions injected along favorable NNW structures. Both Robino & Heberto magmatic phases are distinctive of Mistumis pluton.

Favorable area where NE-SW Robino breccia cuts NNW Heberto shears should be checked (systematically resampled for magnetite or pyrite-rich quartz vein/veinlet) at surface.

Road accessible wholly-owned (no royalties) AU33 gold property covers a prospective 20 km strike of Lower Eastmain greenstone belt, a few km west of Eastmain-1 hydropower facilities, James Bay Eeyou Istchee. It is underlain by large Mistumis intrusion which DIOS proved to be gold-bearing through a large series of gold showing and prospect discoveries, often in association with smaller intrusions.

Core was logged under supervision of Harold Desbiens Geo M.Sc., Qualified Person, and split in two for sampling following standard industry procedures including quality controls and duplicates and assayed for gold at ALS Global laboratory in Val d’Or by fire assay with atomic absorption or gravimetric finish.
