Corporate Updates

AN INTRODUCTION TO MOSAIC’S OPAWICA GOLD PROJECT AND MANAGEMENT

Vancouver, British Columbia – December 8, 2020 – Mosaic Minerals Corp. (“Mosaic” or the

“Company”) (CSE: MOC) is very pleased to remind its shareholders that effective November 16, 2020the

Company’s common shares were listed and are now trading on the Canadian Securities Exchange (the

“CSE”) under the ticker symbol “MOC.C”.

About Mosaic Minerals Corporation

Mosaic Minerals Corp. , founded in 2018 is a Canadian mineral exploration company focused on

unlocking the potential of former Stellar AfricaGold Inc . “Stellar” Opawica Gold Project (“Opawica”)

which is located in Québec’s renowned and very prolific Chibougamau mining district, Nord-du-Québec,

within the famous Abitibi Greenstone Belt.

Mosaic is gold-focused concentrating its exploration efforts where the Company’s growth potential is

the strongest. After incorporation Mosaic acquired Stellar’s Opawica project in a 100% share deal .

Mosaic then completed a Plan of Arrangement with Stellar establishing a shareholder base of more

than 1,000 new Mosaic shareholders. Since the acquisition Mosaic has actively explored Opawica

completing its Phase I exploration program at the end of 2019 with results that warrant advancing with

a Phase II program.

The Opawica Gold Project

Opawica is comprised of two claim blocks , the Philibert I and the Opawica North, located a few

kilometers East and in the structural strike of the Nelligan Iamgold/Vanstar project. Surface sampling

of the Philbert-I block showing by Laurentia Exploration during the 43-101 Technical Report field visit

confirmed Stellar ’s and other historical results returning gold grades of up to 9.24 g/t Au in some

channel sampling of quartz injected structures. The gold mineralization is associated with millimetric to

metric wide quartz veins structure cutting through the Obatogamau rock of Philibert -I block. These

veins are observed a cross a 50-meter-long rock exposure and strike N 1100. Quartz veins contain

tourmaline and pyrite and lies within an epidote -iron carbonates alteration envelope and most

importantly, the structure is open laterally and vertically.

In December 2018, Mosaic mandated Dynamic Discovery to perform a resistivity and Induce d

Polarization (IP) coverage of the Philbert Block to increase the understanding of the geophysical

characteristics of the Philbert -I gold showing. In conclusion, the geophysical response of the gold

mineralization found within the property was better characterised, assisting with th e selection of

priority exploration targets. A total of 200 individual IP anomalies, further grouped as 47 chargeable

lineaments, were defined. Among them, 11 axes are considered with higher potential to relate to

mineralized occurrences and constitute high priority drilling targets.
