"We are very happy to close this private placement with interest exceeding our initial expectations. Encouraged by the current structural strength of the gold market, we are now focusing 100% of our efforts on a fully funded drilling campaign to be carried out on the Golden Island property in the coming winter months," said Jonathan Hamel, President and CEO of Mosaic Minerals.

Each FT Unit consist of one (1) common share of the Company (each, a "Common Share") to be issued as a "flow-through share" within the meaning of the Income Tax Act (Canada) (each, a "FT Share") and one (1) Common Share purchase warrant (each whole warrant, a "Warrant"). Each Warrant will entitle the holder thereof to purchase one Common Share (each, a "Warrant Share") at a price of C$0.09 for a period of 12 months from the date of issuance.

Each Unit consist of one (1) common share of the Company (each, a "Common Share") and one (1) Common Share purchase warrant (each whole warrant, a "Warrant"). Each Warrant will entitle the holder thereof to purchase one Common Share (each, a "Warrant Share") at a price of C$0.07 for a period of 24 months from the date of issuance.

The gross proceeds from the sale of the FT Units will be used by the Company to incur eligible "Canadian exploration expenses" on the Golden Island Project that will qualify as "flow-through mining expenditures" as such terms are defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") related to the Company's projects in Canada. All Qualifying Expenditures will be renounced in favor of the subscribers of the FT Units effective December 31, 2026.

In connection with the Offering, the Company paid a finder's fee of 8% in cash ($20,000 total) and issued 285,714 finder's warrants total ("Finder's Warrants") to two (2) arm-length intermediaries. Each finder's warrant is exercisable to acquire one additional common share at a price of $0.07 per warrant for a period of 24 months from issuance.

All securities issued pursuant to the Offering will be subject to a hold period of four (4) months and one day ending on April 30, 2026. The placement is subject to final approval by the Canadian Securities Exchange.

Golden Island Project Acquisition

Mosaic is also pleased to announce that it has completed the acquisition of the Golden Island Project ("the Transaction"). The Company made a $150,000 cash payment and issued 5,000,000 shares and 2,500,000 warrants to three (3) independent prospectors per the agreement previously disclosed.

The Golden Island project is accessible year-round via Regional Road 113, which connects the towns of Val-d'Or and Senneterre. The property is located on Tiblemont Island (see map) and is accessible by boat from the Tiblemont Lake boat launch just before the town of Senneterre. The site contains the remains of the former Tiblemont Island gold mine. This mine was discovered in the early 1930s but never reached commercial production.

Historical Work and Resources

Extensive work was undertaken following the discovery of the property, then known as "Mining Concession 282," in 1932 by Dr. Theodore Koulomzine, a renowned geologist/geophysicist, until its abrupt abandonment at the outbreak of World War II in 1939. During this period, Tiblemont Consolidated built a camp with multiple permanent buildings, all of which are now gone. Nearly 3,350 linear meters of trenches were dug, as well as a three-compartment vertical shaft sunk to a depth of 155 meters. A 360-meter-long adit was also driven into the hillside at lake level, subsequently connected to the shaft at the 100-meter level. Underground development extends to 1,800 meters at the 360 ​​and 485-meter levels. A 5-ton mill was also in operation. Documents from that time indicate several gold-bearing zones located near the surface that could be mined using open-pit methods. A resource estimate, not compliant with Regulation 43-101, indicates 391,000 tons at a grade of approximately 2.8 g/t at a depth of just under 60 meters (GM41028). Multiple exploration programs have been carried out in previous years. Notably, in 1982, SOQUEM completed a short program of 8 drill holes (1,150 meters), three of which were drilled in the main zone. (See Table 1)

The resource estimates described in this document are considered historical resources and do not comply with the requirements of National Instrument 43-101 - Standards of Disclosure for Mineral Projects. The Company does not consider the historical estimate to be a current mineral resource and does not assert that any or all of the mineralization described will be subsequently converted into mineral resources or mineral reserves defined in accordance with National Instrument 43-101.

It should also be noted that drill hole 82-5, located approximately 1 km northwest of the main zone, intersected a 4.7-meter interval grading 1.31 g/t Au. This drill hole is associated with the same magnetic anomaly as the one linked to the main shaft.

2024 Exploration Campaign.

During the 2024 sampling, the presence of numerous quartz veins was noted in the area surrounding the trenches and the former main shaft. Further fieldwork will be necessary to map and sample all of these veins, which appear to form a gold-bearing corridor several tens of meters wide. The gold-bearing zone is in contact with a high-amplitude magnetic anomaly several kilometers long trending in a northwest-southeast direction.
