Stelmine Canada Mobilizes for Drilling at Courcy

The 3,000-metre Phase 1 diamond drilling program at Courcy, scheduled to commence on or about October 5, 2021, will target gold-bearing zones at the core of a folded thrust fault exposing highly deformed and metamorphosed garnet and sulphide-rich iron formations and amphibolites at the hinge point of a broad antiform.

Gold mineralization observed in Zone 1 appears shallow dipping and is associated with a 21-km-long fault zone discovered by Stelmine geologists who followed up SOQUEM's limited historical work carried out more than a decade ago. SOQUEM drilled just eight shallow holes at Courcy totalling less than 800 metres, all in "Zone 1", and the last hole returned the very significant 42-metre intercept with the core data reviewed by Stelmine geologists. Over the last 3 years, extensive geological and structural mapping of the area by the Stelmine team has produced a robust geological model for Courcy.

High-Grade Gold 2.4 km South of Discovery Hole

Approximately 2.4 km south of SOQUEM's 2006 discovery hole, historical channel sampling returned gold values as high as 167 g/t Au over 0.5 metre in one of several prospective zones already outlined at Courcy ("Zone 4"). Extensive exploration of this zone by Stelmine confirms the gold potential with the discovery of new showings.

Courcy lies at the under-explored eastern edge of the 600-km-long Opinaca metasedimentary basin that also hosts Newmont's Eleonore mine on the western side of the James Bay Territory. Stelmine's total land package in the Caniapiscau district (Courcy, Mercator plus three other properties) now encompasses more than 800 km^2. These properties feature several geological similarities to Eleonore.
