Stelmine to initiate exploration campaign

QUEBEC, QUEBEC--(Marketwired - June 20, 2017) - Stelmine Canada ( << Stelmine >>) (TSX VENTURE:STH) is pleased to announce the start of its exploration campaign on the Courcy flagship mining property located 100 km west of the town of Fermont, Labrador, Quebec. A base camp with a capacity of 16 persons is currently built to receive our exploration team and a drilling crew.

Stelmine's field-based team consists of geologists and technicians who will perform geological and structural mapping, rock and soil sampling and overburden stripping of gold-rich showings unearthed by SOQUEM from 2002-2006. Uninvestigated EM and Mag anomalies identified from previous airborne surveys will be explored to identify new mineralized sites. The western area of the property reveals several geophysical anomalies with a high potential of gold discovery. Results of this exploration will help Stelmine localize drill hole collars for its upcoming drilling campaign planned for this year.

The Courcy site will serve as a base camp in the prospection of the recently acquired Vallard, Joubert, Mercator and Trieste grassroot properties located to the north and northwest of Courcy. These properties will be covered by heliborne Mag surveys to identify new mineralized targets that will be mapped and sampled during fly camps.

Commenting the recent mobilization to the Courcy site, Isabelle Proulx, president and CEO of Stelmine affirms: "Stelmine maintains its aggressive exploration strategy in the eastern Opinaca basin with the build-up of a base camp on the Courcy property. During the forthcoming 4 or 5 months, the company will probe in depth the gold potential of its properties using geophysics, geological mapping, rock and soil sampling and ultimately a drilling campaign".
