Stelmine unearths two new gold mineralized zones on the Courcy property

QUEBEC CITY, April 30, 2019 (GLOBE NEWSWIRE) -- Stelmine (STH-TSXV). Stelmine reports the discovery of two new gold-bearing zones (Courcy 4.0 and 4.1) near the major 21-km long Couteau fault. Last channel sampling, carried out by the Company, lead to the exposure of mineralized outcrops located over 7 km southwest (SW) of the main Courcy 2.4 zone (Figure 1 : https://stelmine.com/en/projects/courcy-properties/ ). Gold values of 1.15 g/t over 2.0 m (Courcy 4.0) and 1.05 over 3.0 m (Courcy 4.1) were detected in highly deformed, finely-bedded pyrrhotite and garnet-rich amphibolites/silicate-facies iron formations situated 550 m north of the Couteau fault (Figure 2).

More than 109 rock samples were collected from outcrops exposed within the SW zone, including 80 channel samples adding-up to 79.5 m in length.

This discovery confirms the gold-potential of the Upper Soulard Formation and the Couteau fault; prompting Stelmine to continue its exploration work on these new outcrops as early as next summer. Future work will reach closer to the Couteau fault defined by positive mag anomalies and high conductivity.

Isabelle Proulx, CEO of Stelmine states: “These new results consolidate our confidence in the gold potential of the Courcy property. The discovery of the new gold zones suggests the occurrence of mineralized horizons extending to the Courcy 2.4 site.”

Geology of the Courcy property

At the center of the property, the Couteau fault separates the Soulard Formation into two volcanic units at the level of an assemblage of sulfurized, garnet-rich silicate facies iron formations and iron-rich amphibolites. The best gold results came from pyrrhotite-rich amphibolite and iron formation samples within and at the margin of this major fault.

The geology of the Courcy property comprises a large, strongly-deformed (meta-) sedimentary basin located in the eastern and northern areas of the property. The basin is composed of grauwackes, mudstones., quartz arenites, quartzites and monogenic/polygenic conglomerates together with amphibolites. The Courcy Formation is mainly characterized by a metavolcanic gneissic assemblage of metandesites, tuffs and migmatitic paragneiss crosscut by dioritic and tonalitic sills. South of the property, a series of tonalitic, granodioritic and monzogranitic rocks forming the Atticoupi Suite is in contact with the metasedimentary and metavolcanics assemblages.

QA/QC Protocol

Stelmine implemented a strict QA/QC protocol in processing all rock samples collected from the Courcy property. The protocol included the insertion and monitoring of appropriate reference materials, in this case high concentration (OREAS-210) and low concentration (OREAS-252) certified gold standards, blanks and duplicates, to validate the accuracy and precision of the assay results. All collected rock samples were put in sturdy plastic bags, tagged and sealed in the field under the supervision of professional geologists. The sample bags were then put in rice pouches and kept securely in a field tent before being sent by floatplane to the city of Wabush. Transport to Actlabs laboratories in Ancaster, Ontario was made by truck from reliable transport companies. Gold was analyzed by fire assay method (Au-FA_ICP).
