Stelmine Canada Identifies New Meridian Gold Zone in Mercator Surface Channel Sampling Return: 2.07 g/t Au over 27.50 m, 2.16 g/t Au over 16.0 m, and 2.13 g/t Au over 12.50 m
QUÉBEC, July 27, 2022 (GLOBE NEWSWIRE) — Stelmine Canada (« Stelmine ») (STH-TSXV) Stelmine Canada is pleased to divulgate gold assay results of channel and grab samples collected within the 100% owned Mercator property located in northeastern Quebec. At the core of the property, the Meridian Zone, yielded 22 channel sites carrying significant gold values such as 2.07 g/t Au over 27.5 m, 2.16 g/t Au over 16.0 m and 2.13 g/t Au over 12.5 m (Fig. 1 and Table 1). Grab samples also include high gold concentrations such as 18.2 g/t, 9.27 g/t, and 6.93 g/t Au. The Meridian Zone constitutes a 2.5 km x 500 m mineralized corridor set in a unique assemblage of highly metamorphosed igneous mafic rocks and iron formations 5 to 20 m thick, dipping 30°-40° to the NW. Sitting on a hill characterized by positive magnetic anomalies, it is bounded by low angle thrust faults (Fig. 1 and 2).
Since 2020, a total of 332 channel and 233 grabs samples were collected from the Meridian Zone and throughout the 389 km2 property. Gold concentrations were distributed as follows:
|Channel sample||Grab sample|
|26% > 1 g/t Au||7% > 1 g/t Au|
|71% > 200 ppb Au||18% > 200 ppb Au|
Isabelle Proulx President and CEO declares: “The gold results at Mercator are notable for their continuity and large distribution along a 2.5 km mineralized corridor. The Meridian Zone mineralization is still considered orogenic with several of the characteristics attributed to other gold deposits of the Canadian shield. The results provide numerous gold-bearing targets to be investigated in the forthcoming maiden drill program. Stelmine continues to build upon the new Caniapiscau mining district for which systematic exploration has just begun.”

The Mercator Property: A Unique Metallotect in the La Grande/Opinaca Subprovinces of Quebec
The property is located 200 km west of Fremont, Quebec, at the eastern limit of the Opinaca sedimentary basin near the La Grande-Opinaca boundary. Gold mineralization occurs within faulted and folded granulite facies mafic rocks (basalts and gabbros) and iron formations interlayered with a thick assemblage of migmatized paragneiss forming a large sedimentary basin within the La Grande/Opinaca subprovinces. Löllingite/arsenopyrite, pyrrhotite, pyrite, and chalcopyrite are the principal sulphide minerals associated with gold.
Gold mineralization at Mercator represents a rare occurrence associated with highly metamorphosed (granulite) mafic rocks and iron formations within the Archean greenstone belts of Quebec. Gold showings in granulitic facies rocks were discovered in the northern Ashuanipi subprovince (i.e., Lac Pau and Lilois sectors) in deformed and sheared tonalites and in iron formations within migmatized metasediments. However, the closest analogue to the Meridian Zone may be found in highly metamorphosed greenstones of the Yilgran craton of Western Australia. There, gold mineralization at the Grifﬁns Find mine is associated with folded quartz–clinopyroxene veins and quartz–clinopyroxene–garnet wallrock assemblages. Sulphides occurring with gold are dominated by pyrrhotite, arsenopyrite and löllingite, with minor sphalerite and chalcopyrite. Arsenic, copper, and zinc are important indicator elements used for regional gold exploration targeting.
The 2022 field season will be largely devoted to exploration work leading to a maiden drilling program during the summer season. A 25 km IP survey will be performed on the Meridian Zone to complement the heliborne MAG survey accompanied by detailed geological and structural mapping of the Zone and till sampling.

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 and low concentration 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 geologists in training. 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 dependable transport companies. Gold was analyzed by fire assay (1A2_ICP_50 g) or the INAA+ICP_OES (1H) methods. Other trace element concentrations were obtained via the 1H method.
About Stelmine Canada
Stelmine is a junior mining exploration company pioneering a new gold district (Caniapiscau) east of James Bay in the under-explored eastern part of the Opinaca metasedimentary basin where the geological context has similarities to the Eleonore mine. Stelmine has 100% ownership of 1,277 claims or 655 km² in this part of northern Quebec, highlighted by the Courcy and Mercator Projects.
