Mosaic Completes Canalask Claims Assembly

Corporate Updates

MOSAIC MINERALS

COMPLETES CANALASK CLAIMS ASSEMBLY

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

Minerals.

The Canalask Property assembl y 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 r eported and well

documented.

The mineralization of the Lac Dunphy showing is described as of stratiform type, oriented N195 0-2100.

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 returne d 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.

from those predicted herein include, without limitation: that the remaining conditions to the Arrangement will not be satisfied; that the business prospects

and opportunities of the Company will not proceed as anticipated; changes in the global prices for gold or certain other commodities (such as diesel,

aluminum and electricity); changes in U.S. dollar and other currency exchange rates, interest rates or gold lease rates; risks arising from holding derivative

instruments; the level of liquidity and capital resources; access to capital markets, financing and interest rates; mining ta x regimes; ability to successfully

integrate acquired assets; legislative, political or economic developments in the jurisdictions in which the Company carries on business; operating or technical

difficulties in connection with mining or development activities; laws and regulations governing the protection of the enviro nment; employee relations;

availability and increasing costs as sociated with mining inputs and labour; the speculative nature of exploration and development; contests over title to

properties, particularly title to undeveloped properties; and the risks involved in the exploration, development and mining b usiness. Risks and unknowns

inherent in all projects include the inaccuracy of estimated reserves and resources, metallurgical recoveries, capital and op erating costs of such projects,

and the future prices for the relevant minerals.
