MOSAIC CLOSES $1.36M OVERSUBSCRIBED PRIVATE PLACEMENT

Mosaic Minerals Corp. has closed the final tranche of a private placement of units and flow-through units for aggregate gross proceeds of $1,360,251. Driven by strong demand, the offering was oversubscribed by 36 per cent above the original financing target.

Private placement

The company announces that it has completed the final tranche of its previously announced private placement through the issuance of 2.75 million flow-through (FT) units at a price of 10.5 cents per FT unit and 3.36 million units at a price of 8.5 cents per unit, for gross proceeds of $574,350. Including the first tranche (see news release dated Sept. 23, 2026) and the second tranche (see news release dated Oct. 8, 2026), the company raised aggregate gross proceeds of $1,360,251 under the offering, 36 per cent above the original financing target.

"With this funding secured, we are well positioned to launch our inaugural drilling campaign at the Golden Island property and aggressively test these highly prospective gold zones," concluded Jonathan Hamel, president and chief executive officer of Mosaic.

Each FT unit consists of one common share of the company to be issued as a flow-through share within the meaning of the Income Tax Act (Canada) and one common share purchase warrant. Each warrant entitles the holder to purchase one common share at a price of 17 cents for a period of 12 months from the date of issuance.

Each unit consists of one common share of the company and one common share purchase warrant. Each warrant entitles the holder to purchase one common share at a price of 12 cents for a period of 24 months from the date of issuance.

Jonathan Hamel, president, chief executive officer and director of the company, purchased directly 800,000 flow-through units for aggregate consideration of $84,000. The participation of the insiders in the offering constitutes a related party transaction under Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions, but is exempt from the formal valuation and minority approval requirements pursuant to sections 5.5(a) and 5.7(1)(a) of MI 61-101 as neither the fair market value of the securities issued to, nor the consideration paid by, the insiders exceeded 25 per cent of the company's market capitalization. The company did not file a material change report with respect to the participation of the insider at least 21 days prior to the closing of the private placement as the insider participation was not determined at that time.

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 qualify as flow-through mining expenditures, as such terms are defined in the Income Tax Act (Canada), in connection with the company's projects in Quebec, Canada. All eligible expenditures will be renounced in favour of the subscribers of the FT units, effective Dec. 31, 2026.

In connection with the offering, the company paid cash finders' fees of 6 per cent (totalling $46,056) and issued a total of 469,835 finders' warrants to four arm's-length finders. Each finder's warrant is exercisable to acquire one additional common share at a price of 8.5 cents per warrant for a period of 24 months from the date of issuance.

All securities issued in connection with the offering will be subject to a hold period of four months and one day, ending on Jan. 22, 2027, or Feb. 2, 2027, or Feb. 17, 2027.

The offering is subject to final approval by the Canadian Securities Exchange.
