2.81 g/t Au on 1 m discovered by Stelmine


Québec, February 26, 2019 Stelmine Canada (« Stelmine ») (STH-TSXV) reveals the results of its 2018 exploration campaign on the Trieste property. Channel sampling carried out on a chloritized amphibolite rock at proximity of a silicate/oxide iron formation exposed in the eastern sector of the property yielded a gold value of 2.81 g/t on 1 m. The assay corroborates the 1.10 g/t Au concentration obtained in 2017 by Stelmine on a composite sample collected near the iron formation (Figure 1). The Trieste property is located within the Trieste greenstone belt less than 80 km SW of the Trans-Taiga road in the James Bay Territory.

Isabelle Proulx, President and CEO of Stelmine affirms: “These results combined with those obtained on the Courcy property let us believe the eastern portion of the Opinaca/La Grande sub-provinces will become an important gold district. As testified by the results obtained by several junior mining companies, the gold mineralization occurring within the wallrocks of the iron formation validates the gold potential of the Trieste greenstone belt”.


In 2018, Stelmine geologists completed geological mapping of the property accompanied by grab and channel sampling. The exploration work identified folded magnetic iron formations (oxide and silicate facies) interbedded with metasedimentary and mafic to intermediate metavolcanic rocks (amphibolites).  Gabbroic sills are associated with the amphibolite metavolcanics. The metasedimentary rocks consist of paragneiss and migmatized paragneiss with metachert/quartzite forming part of the Solomon Fm. Mapped plutonic rocks consist of granodiorite, tonalite, granite and pegmatitic granite.

Gold mineralization occurs in sulfurized amphibolites near iron formations containing magnetite, grunerite, garnet and sulfides (pyrite, pyrrhotite, arsenopyrite and chalcopyrite) and are cut by sulfide-bearing quartz veins. The iron formations display oxide and silicate facies and is interbedded with chert.

Additional information

The Society wishes to correct an inaccurate statement made in the press release of February 12, 2019. Stelmine has issued at total of 850 000 share options, according to their option plan, including 650,000 share options to directors, managers and employee to be exercised within 5 years. The Society also granted 200 000 share options to consultants to be exercised within 1 year.

QA/QC Protocol

Stelmine implemented a strict QA/QC protocol in processing all rock samples collected from the Trieste 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 at the Mirage Outfitter base camp on the Trans Taiga road. 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).
