About Mosaic Minerals Corporation

Mosaic Minerals Corp., founded in 2018,is a Canadian mineral exploration companyfocused
onunlocking the potential of former Stellar AfricaGold Inc. “Stellar”Opawica Gold Project (“Opawica”)
which is located inQuébec’s renowned and very prolific Chibougamau mining district, Nord-duQuébec, 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’sOpawicaprojectin a 100% share deal.
Mosaic then completed a Plan of Arrangement with Stellar establishinga shareholder baseof more
than 1,000 new Mosaic shareholders. Since the acquisition Mosaic has actively explored
Opawicacompletingits Phase I exploration program at the end of 2019 with results that warrant
advancing witha Phase II program.

The Opawica Gold Project

Opawica is comprised of two claim blocks, the Philibert I and the Opawica North, both located a few
kilometers East and in thegeological and 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-tourmaline veins structure cutting through the Obatogamau rock of
Philibert-I block. These veins are observed across a 50-meter-longrock exposure and strike N1100
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 toperform a resistivity and
InducedPolarization (IP) coverageof 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, assistingwith the
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.
