MOSAIC MINERALS BEGINS PROSPECTION WORK ON AMANDA AND ANNOUNCES CORRECTION REGARDING THE ANNUAL GENERAL MEETING

Mosaic Minerals Corp. has started a 10-day prospecting program on the Amanda project. The team, composed of a geologist and two technicians, will revisit and sample the different pegmatites listed in previous years by the Ministry of Natural Resources and Forests (MRNF) and Vanstar Mining Resources Inc.

Different pegmatites known on the Amanda project were also intersected in several historical drillings carried out from 1997 to 2010 but no analysis was done to verify the presence of lithium in them. The technical team will therefore try to find these old drillings and take, if possible, several samples for analysis.

The company plans to take a few hundred samples from the various pegmatites listed and hopes to find new ones. The presence of indicator minerals such as beryl, spodumene and rubidium has been observed at different locations on the property.

An access path will also be marked in anticipation of future drillings on this project. The campaign will benefit from helicopter support, which will greatly improve the productivity of the team on the ground.

The Amanda project also contains very interesting gold potential and the various gold showings, notwithstanding the lithium results, could be the subject of exploration work in 2024.

Lithium SM

Twelve days of prospecting and sampling were carried out on the Lithium SM project in September, 2023. A total of 93 samples were taken in key areas of the property. Most samples come from pegmatitic intrusives with a thickness varying from a few tens of centimeters to more than one metre.

In the northern part of the property, certain samples taken by the technical team indicated the presence of copper and zinc. Access to the property seems acceptable for the northern part while it is more difficult to access the southern part without a forest road. The technical team was therefore unable to reach the planned targets in this sector. Few samples were taken in that area.

The company is awaiting results from the ALS Canada Ltd. analysis laboratory.

Lichen project

Following a sampling survey, 27 samples were taken from the entire Lichen project during the summer of 2023. The results obtained do not demonstrate the presence of lithium or other strategic minerals. However, this project remains interesting for the presence of base metals and gold.

Annual general meeting

The company also notifies shareholders that the Internet address required to access the annual general meeting included in the notice of meeting and the proxy form of the company sent to shareholders on Oct. 11, 2023, has been corrected.

The meeting will be held on Nov. 2, 2023, at 10 a.m. (EST) at 410 St-Nicolas, suite 236, Montreal, Que., H2Y 2P5, and on-line.

The technical content of this press release has been reviewed and approved by Gilles Laverdiere, PGeo, an independent consulting geologist and a qualified person as defined in National Instrument 43-101.
