Vancouver, British Columbia – January 13, 2021 – Maurice Giroux, President and CEO of Mosaic
Minerals Corp. (“Mosaic” or the “Company”) (CSE: MOC) is pleased to announce that the claims
assembly of the CANALASK multi-metallic project in Northern Quebec is complete.

The Canalask property is made up of 16 mining claims covering 770 hectares to the North West shore of
Lake Dunphy located 150 km NNW of Shefferville in SNRC 24B04. The claims are 100% owned by Mosaic

The Canalask Property assembly was undertaken following an extensive compilation by Mosaic
Minerals of all available mineral showings listed in the Quebec Ministère de l’Énergie et Ressources
data base in Quebec.

The Canalask Property encloses 2 well documented multi-metallic showings namely, the Canalask and
the Lac Dunphy surface showing of copper, zinc, silver and gold.

The mineralization of the Canalask showing is described in the Ministère de l’Énergie et des Ressources
Naturelles of Québec’s archive as being of veins type at the contact of a gabbro and a mudstone unit
and consist of chalcopyrite, malachite, and minor bornite. Historically, a surface chipped channel
sample grading 8% Zn, 0.90% Cu, 62.0g/t Ag and 1.25 g/t Au over 30 metres is reported and well

The mineralization of the Lac Dunphy showing is described as of stratiform type, oriented N1950
It is characterized by mineralized bands of massive calcite of centimetric to decametric width. The main
horizon can be observed on as long as 45 metres over width of 0.25 up to 1.0 metre. On that structure,
a chosen grab sample reported 18.25% Cu and a drill hole reported grades of 10.45% Cu, 0.17g/t Au,
18.5 g/t Ag over 0.5 metre. In addition, the Lac Dunphy showings returned grades of 3.63% Cu, 8.4 g /
t Ag over 1 m, (trench); 4.99% Cu, 17.6 g / t Ag

The polymetallic type mineralization is of particular interest because the mineralized showings of this
type found so far indicate that this is a regional phenomenon with the potential to host appreciable
quantities of metals. The available data suggests that the property appears to have potential for
discovery and that further investigation is warranted.
