Significant gold values extending over more than one km for

QUEBEC CITY, Feb. 12, 2019 (GLOBE NEWSWIRE) -- Stelmine Canada (« Stelmine ») (STH-TSXV) submits the results of its exploration campaign conducted on the Mercator property located less than 85 km NW of the Courcy flagship property. Gold values provided by three grab samples (Figure 1) yielded:

• 7.44 g/t Au with 1090 ppm As
• 0.45 g/t Au with 87 ppm As
• 0.44 g/t Au with 19 ppm As

The mineralized sites form the SW extension of the rusted gold-mineralized Biblain showing identified 1 km away by the MRNQ (3.0 g/t Au; Leclair et al., 1998).

Stelmine geologists visited more than 38 sites and collected 22 grab samples during a 5 day heliborne campaign completed during September 2018. The mineralized zones constitute sulfurized and oxidized metasedimentary sequences (2-10 %; mainly pyrrhotite±pyrite) within amphibolite-rich (grunerite) and garnet-rich layers possibly forming iron formations.

Isabelle Proulx, President and CEO of Stelmine declares: “The Mercator property, although sparsely explored, revealed significant gold values extending for 1 km along strike and associated with iron formations. This motivates Stelmine to pursue further its exploration within this prospective zone.”

Regional geology The Mercator property is located within the extension of the Opinaca metasedimentary sub-province just south of the western segment of the Ashuanipi sub-province and east of the contact with the La Grande sub-province. Most metasedimentary rocks are constituted of greywackes, arenites, siltstones and iron formations (mostly chert). The rocks are highly metamorphosed and migmatized and are largely represented by paragneiss some of which may be dioritic gneiss. The rocks probably belong to the Hublet Group (Mercator Fm). The main plutonic rocks are constituted of migmatized tonalites revealing 15-35 felsic mobilizates of granitic composition (Figure 1).

Additional information Stelmine also discloses the issuance, as of February 12, 2019, of a total of 850 000 stock options granted according to the Company’s Option Plan. 700,000 options were granted to directors, executive officers and employee for a period of 5 years. The Company also allocated 150,000 options to a consultant for a period of 1 year. All options are issued at the grant date at an exercise price of 0.15$ and each option may be exercised during each period specified above from the grant date. Subject to approval of the TSX Venture Exchange.

Stelmine is proud to announce the nomination of Julie Lemieux as the Company’s CFO. Ms. Lemieux has been working in the accounting field for more than 22 years. She has been a controller at the company since last year. Previously, she acted for various private companies as a controller and worked for over 5 years at a public company where she gained the experience that adds value to Stelmine. Furthermore, Stelmine announces the resignation of Mr. Paul-André Lemieux, CPA, CA. The Company expresses his gratitude for his implication and meticulous work.

QA/QC Protocol Stelmine implemented a strict QA/QC protocol in processing all rock samples collected from the Mercator 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) and other trace metals via TD-MS or TD-ICP methods (ME-MS61).
