March 20, 2025 – Montreal, Quebec. Mosaic Minerals Corporation (“Mosaic” or “The Company”) announced today its decision to divest itself of all its lithium projects acquired through staking in recent years to refocus on the development of its Gaboury project, a nickel showing located in Témiscamingue, Quebec.
Gaboury Project: Promising Nickel Potential
- 95 claims – 5,453 hectares
- A magnetic anomaly of over 8 km
- Nickel confirmed over widths ranging from 27 m to 206 m
- Grades up to 0.48% Ni
- Zones open at depth and laterally
This project, 100% owned by Mosaic, covers a vast area crossed by a large-scale magnetic anomaly, already tested by around twenty drill holes drilled since the 2010s. This work has revealed a consistent presence of nickel, confirmed up to 275 m deep and extending over 1,200 m to the west and 1,700 m in its central and eastern part. The significant presence of gold and zinc is also noted in several drill holes intersecting this magnetic anomaly. Anomalous values for cobalt, magnesium and lead are also found.
“After a thorough analysis of our project portfolio, we have decided to focus our resources and efforts on the Gaboury project. Nickel is a critical metal in demand and Quebec is a mining jurisdiction ideally positioned to play a key role in this market. With very promising drilling results and rapidly growing global demand, we firmly believe that this project represents a major opportunity for our company and our shareholders,” said Jonathan Hamel, President and CEO of Mosaic.

Strategic Metal Distribution
Pike West: Good concentration of nickel (Ni), cobalt (Co), and zinc (Zn)
Pike Central and East: Confirmed presence of gold, zinc, and nickel
Mosaic intends to resume drilling in the Pike West zone, where the highest nickel and cobalt grades have been recorded. A new 3,000-meter program is planned to explore the potential at depth and establish a potential geological resource to maximize the value of the deposit.
Amanda Project
Regarding the Amanda project, located in northern Quebec, the company’s management will attempt to find a partner for its development. Various prospecting and sampling surveys conducted over the past few years have confirmed its gold-bearing character. Numerous showings have been discovered in the eastern and northern part of the project, adding to the main gold showings located in the southern part of the Amanda project.
