MOSAIC MINERALS EXPANDS CRISAFY PROPERTY IN CHIBOUGAMAU AREA

Vancouver, British Columbia – January 21, 2021 – M. Maurice Giroux, President and CEO of Mosaic

Minerals Corp. (“Mosaic” or the “Company”) (CSE: MOC) is pleased to informreport that the Company

expanded the Crisafy Project, adding 5 claims to the South for an extra 280 hectares to the initial Crisafy

Gold Property located in Crisafy Township, SNRC 32G07 in the Chibougamau area in Quebec.

The Crisafy Property, originally 22 claims (see news release January 6, 2021), now comprises 27 mineral

claims covering 1, 515 hectares located in the very prolific Obatogamau neo-archean volcanic

formation. The formation is composed mainly of basalt and andesitic basalt, that hosts Iamgold’s

Nelligan and Monster Lake gold deposits as well as the Northern Superior ’s recent Lac Surprise

discovery, a few kilometers to the north (see location map here).

Crisafy Project – Mosaic Minerals Corp.

The decision to expand the perimeter followed a detailed examination of the geological and geophysical

context of the property area. A geological map, derived from an interpretation by CONSOREM,

Consortium de Recherche en Exploration Minérale of Université du Québec à Chicoutimi, of all the

deformation corridors extrapolated from electromagnetic conductor axis (INPUT) of the project area .

The map shows the position of the Nelligan and Monster Lake Iamgold discoveries and of the recent

Northern Superior Lac Surprise discovery within the deformation corridors. Mosaic has secured its three

blocks of claims, namely, Philbert 1, Opawica North and Crisafy within those corridors and the map

illustrates their strategic positioning in reference to existing deposits and new discoveries in the area.
