TORONTO, ON / ACCESS Newswire / September 29, 2025 / McFarlane Lake Mining Limited (CSE:MLM)(OTCQB:MLMLF) ("McFarlane Lake" or the "Company"), a Canadian gold exploration and development company, is pleased to announce that it has closed the strategic acquisition of a 100% interest in the Juby Gold Project and 25% joint venture interest in the adjacent Knight property (together, the "Acquisition") from Aris Mining Holdings Corp. ("AMHC"), a wholly-owned subsidiary of Aris Mining Corporation ("Aris Mining"), along with the associated financing transactions.

Terms of the Acquisition were first announced July 7, 2025, and the purchase price was paid through a combination of US$13,165,677 million cash and the issuance of 82,023,746 common shares of the Company (the "Consideration Shares") to Aris Mining.

The addition of this project to McFarlane Lake's portfolio is accretive to our business and to shareholder value. This acquisition transforms our company into one with a significant gold resource base at a time when gold prices are at historic highs. We look forward to advancing exploration and development activities at the Juby Gold Project and expect to announce an updated Mineral Resource Estimate (MRE) compliant to NI 43-101 standards within the coming days. We would like to thank Aris Mining and look forward to working with them as a 19.9% equity owner in McFarlane Lake. Concurrently, we look forward to engaging the local communities respecting the values and Treaty rights of the First Nations and aim to develop the project in a sustainable and transparent manner."

Financing Transactions

US$15 Million Debt Financing

In connection with the Acquisition, McFarlane Lake is pleased to announce the closing of its previously announced debt and equity financing transactions.

The debt financing was completed by way of a non-brokered private placement of 15,000 debenture units (the "Debenture Units") of the Company (the "Debenture Offering") for aggregate gross proceeds of US$15 million.

Each Debenture Unit was comprised of (i) one 15% senior secured debenture (the "Debentures") having a face value of $1,000 and maturing 13 months from the date hereof (the "Maturity Date"); and (ii) 3,200 common share purchase warrants of the Company (the "C$0.15 Warrants"). Each C$0.15 Warrant entitles the holder to acquire one common share of the Company at a price of C$0.15 per share for a period of three years following the date of issuance.

The Debentures are redeemable at any time at a price equal to 100% of the principal amount, plus accrued and unpaid interest, subject to a minimum of six months' interest (less any interest already paid) if redeemed before holders have received that amount in interest (the "Prepayment Penalty"). For clarity, no Prepayment Penalty applies once holders have received six months' interest. In addition, all other accrued and outstanding amounts under the indenture are payable upon redemption.

The Company has used the proceeds of the Debenture Offering as follows: (i) US$10 million to fund a portion of the cash consideration payable for the Acquisition; (ii) approximately US$2.4 million deposited into escrow as an interest reserve pursuant to the terms of the Debentures; and (iii) the balance allocated to working capital and general corporate purposes, including transaction expenses and fees. In connection with the Debenture Offering, certain eligible finders were paid a cash fee equal to 5% of the gross proceeds attributable to subscriptions sourced by such finders.

C$8.46 Million Equity Financing

The equity financing was completed by way of a non-brokered private placement of (i) 56,106,667 units of the Company (the "Units") at a price of C$0.15 per Unit (the "Unit Offering"); and (ii) 300,000 flow-through shares of the Company (the "FT Shares") at a price of C$0.15 per FT Share (the "FT Offering"), for aggregate gross proceeds of C$8,461,000. The FT Shares qualify as "flow-through shares" within the meaning of subsection 66(15) of the Income Tax Act (Canada). The Unit Offering was conducted under the Listed Issuer Financing Exemption (as defined below) and met the minimum aggregate offering amount of C$6,500,000.

Each Unit consists of one common share of the Company (each, a "Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder to acquire one common share at a price of C$0.25 per share for a period of three years from the date of issuance.

The net proceeds from the Unit Offering were applied, in part, to fund a portion of the cash consideration payable in connection with the Acquisition. The balance of the net proceeds will be used for general working capital and other corporate purposes, as more particularly described in the Company's offering document (the "Offering Document").

The gross proceeds received from the sale of the FT Shares will be used to incur eligible "Canadian exploration expenses" that will qualify as "flow-through mining expenditures," as such terms are defined in the Tax Act (the "Qualifying Expenditures"). All Qualifying Expenditures will be renounced in favour of subscribers of the FT Shares effective December 31, 2025.

An Offering Document related to the Unit Offering remains available under the Company's profile at www.sedarplus.ca and on the Company's website at https://mcfarlanelakemining.com/. Purchasers of Units issued under the Listed Issuer Financing Exemption have the benefit of the Offering Document and the rights provided under the Listed Issuer Financing Exemption.

In connection with the Unit Offering and FT Offering, the Company paid certain eligible finders' fees consisting of cash payments of up to 8.0% of the gross proceeds raised from investors introduced by such finders, except that fees payable in respect of investors identified on a president's list were reduced to 2.0%.

All Units distributed in connection with the Unit Offering were issued and sold pursuant to the "Listed Issuer Financing Exemption" available under Part 5A of National Instrument 45-106 - Prospectus Exemptions (the "LIFE Exemption" and in reliance on Coordinated Blanket Order 45-935 - Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (the "Order"). Pursuant to the LIFE Exemption, all Units issued under the Unit Offering to Canadian subscribers are not subject to a hold period in Canada in accordance with applicable Canadian securities laws and the policies of the Canadian Securities Exchange (the "Exchange"). All other securities not issued pursuant to the LIFE Exemption, namely, the Debenture Units and FT Shares, are subject to a statutory hold period in accordance with applicable Canadian securities laws, expiring on January 30, 2026. The Debenture Offering, Unit Offering and FT Offering remain subject to the final acceptance of the Exchange.

The securities described herein have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from the registration requirements. This press release does not constitute an offer to sell or a solicitation of an offer to buy any securities in any jurisdiction in which such offer, solicitation, or sale would be unlawful.

The Company did not file a material change report with respect to the insider participation more than 21 days before the expected closing of the Debenture Offering, Unit Offering or FT Offering, as the details and amounts of the insider participation were not finalized until closer to the closing and the Company wished to close the transaction as soon as practicable for sound business reasons.
