Stelmine Canada Ltd.: New interpretations of gold-bearing zones on the Courcy property

QUEBEC, QUEBEC--(Marketwired - Aug. 22, 2017) - Stelmine Canada Ltd. (« Stelmine ») (TSX VENTURE:STH) is updating the current exploration work undertaken on its Courcy flagship property located in the eastern segment of the Opinaca basin near the Quebec/Labrador border. Since mid-June 2017, our field crew took large steps toward the reinterpretation of known gold-bearing zones.

Presently, our exploration work focuses on the Courcy property where previous drilling by another mining company in 2006 revealed an intersection of 4,5 g/t Au @ 42 m (including 12 g/t Au @ 13,5 m; Ref : PR, December 2016).

Our results suggest a new geological interpretation of the terrane based on a metallogenic model relating the gold mineralization to silcate-facies Banded Iron Formations (BIFs) deposited within a large basin dominated by deformed and metamorphosed metasediments (conglomerates, sandstones, quartzites) associated with mafic to felsic volcanic assemblages (basalts, rhyodacites, rhyolites).

"We are delighted with the reinterpretation of the geological map of the property, which opens the door to new discoveries since only 25% of the property (156 km²) will be investigated during this year's exploration. These discoveries confirm our desire to acquire new properties located in the eastern portion of the Opinaca subprovince, the latter being the site of the Éléonore Mine to the west" stated Isabelle Proulx, CEO of Stelmine.

A crew of eight employees composed of senior and junior geologists and technicians are carrying out geological mapping, rock sampling (grab and channel) and overburden stripping that allowed:

• The reinterpretation and clarification of the former geological map
• Performing overburden stripping covering hundreds of m² to enlarge the mineralized zones and expose new areas
• Collecting over 338 rock samples for analyses

Stelmine is completing the exploration of its Courcy property. The work results, including precious and base metals assays, will enable the emplacement of future drill holes.
