Stelmine to resume exploration of the Mercator gold property

QUEBEC CITY, July 29, 2020 (GLOBE NEWSWIRE) — Stelmine Canada. (« Stelmine ») (STH-TSXV) is pleased to report it is resuming the exploration work on its Mercator property. The property is located at the eastern limit of the Opinaca sedimentary basin near the La Grande-Opinaca contact which is viewed as the most gold-prospective within the James Bay Territory. The eastern segment of the La Grande-Opinaca contains several gold mineralized zones associated with iron formations.

The exploration program will investigate in more details a NW/SE-oriented gold-bearing corridor extending for at least 1 km from which grab sampling yielded gold values of 7.44 g/t Au (press release, February 2019) and 3.0 g/t Au (Biblain showing, Leclair et al, 1997; RG97-11). Stelmine strongly believes an extended exploration will lead to the discovery of new mineralized showings based on the exposures of iron formations, the high arsenic content and the strong deformation of all lithologies.

Isabelle Proulx, President and CEO of Stelmine asserts: “We are eager to perform our first sustained work campaign on this property. Indeed, previous exploration completed in few days allowed the discovery of a second gold showing. We are currently at a phase where we can demonstrate the extension of the mineralized zone and develop a key sector to explore for gold due to its proximity to the Courcy gold property. The occurrence of an important mineralization at Mercator would certainly increase the potential of the eastern La Grande-Opinaca contact that could indicate a new gold-rich sector seldom investigated until now.”

The mineralized zones discovered by Stelmine consist of sulfurized and oxidized (2-10% sulphides, mostly pyrrhotite-pyrite) banded amphibolite-rich (grunerite) and garnet-bearing layers that could represent silicate-facies iron formations (i.e. 7.44 g/t Au et 1090 ppm As, 0.45 g/t Au et 87 ppm As and 0.44 g/t Au and 19 ppm As). The Biblain showing unearthed by the MERQ contains pyrite-pyrrhotite, arsenopyrite veins and yielded Au concentrations from 0.84 to 3.0 g/t with high As concentrations (0,22-0,96 %). These poorly investigated showings correspond to a positive Mag anomaly related to the presence of iron formations and are situated on a topographic high exposing many outcrops (Figure 1).

The work program is planned for 25 days and will be completed during the 2020 summer period. The program contains three components:

A geological and structural mapping of the gold-bearing corridor extending for more than 1 km that includes a search for mineralized extensions; followed by more regional work on target zones identified during the 2018 campaign.

Further investigation of high gold potential zones through overburden stripping and closely spaced channel sampling.

A regional till survey to permit the extraction of heavy minerals and analysis of gold grains and sulphide minerals.
