Stelmine acquires its fifth property: Joubert

QUÉBEC CITY, QUÉBEC--(Marketwired - Feb. 28, 2017) - Stelmine Canada Ltd. (« Stelmine ») (TSX VENTURE:STH) continuing its recent wave of acquisition of mining properties located at the prospective eastern contact of the Opinaca and La Grande subprovinces that bears similar geological features to that of Goldcorp Éléonore mine, Stelmine acquired the Joubert property. This fifth property, staked through the MRNQ GESTIM website, is located 55 km NE of the Renard diamond mine which is accessible by Road 167. Joubert, 100% owned by Stelmine, is constituted of 108 continuous claims totaling 60 km².

During the mid-2000s, exploration work conducted by Virginia Mines in greenstone belts exposed northeast of the Joubert property lead to the discovery of gold showings. A recent large scale geological map of NTS sheets 33H01, 23E03, 23E04 compiled from previous work and new mapping carried out by Quebec's MERN (CG-2015-02) enabled the identification of prospective areas for Au-Cu mineralization (see map on www.stelmine.com).

The geology of the Joubert property manifests some of the characteristics associated with gold mineralization occurring at the periphery of the western Opinaca sedimentary basin at the contact with the La Grande subprovince (e.g. Éléonore, Zone 25, La Grande-South). Moreover, the contact between the subprovinces is manifested by regional EW to NE-oriented major plurikilometric-long fault zones. In Joubert, the exposed La Grande rocks are largely constituted of highly metamorphosed paragneiss and diatexites (Salomon River Fm.), amphibolite rocks (basaltic) forming the Trieste Fm. and of gneissic to foliated granodiorites and tonalites of the Joubert Suite. The Opinaca lithologies are represented the paragneiss, diatexites and metatexites of the Laguiche Complex.

«With the acquisition of the Joubert property, Stelmine follows an aggressive strategy of discovering high- potential gold properties set in a similar geological environment to that of the Éléonore Mine. This new acquisition brings the Company portfolio to five properties totalling 707 claims and covering 368 km²» stated Isabelle Proulx, president and CEO.
