Heritage Mining Announces Non-Brokered Private Placement of Flow-Through Shares and Units

Pursuant to the Offering, the Company intends to issue up to 18,750,000 FT Shares of the Company at a price of $0.04 per FT Share, for aggregate gross proceeds of up to $750,000, and up to 10,000,000 Units of the Company at a price of $0.04 per Unit, for aggregate gross proceeds of up to $400,000.

Each FT Share will qualify as a "flow-through share" as defined in subsection 66(15) of the Income Tax Act (Canada)(the "Act"). The proceeds of the FT Shares will be used to incur eligible "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" as both terms are defined in the Act (the "Qualifying Expenditures") related to the Company's projects in Ontario, Canada. The Company plans to incur Qualifying Expenditures on or before December 31, 2027 (or such other period as may be permissible under applicable tax legislation), and to renounce all the Qualifying Expenditures in favour of the subscribers of the FT Shares effective December 31, 2026.

Each Unit will consist of one common share in the capital of the Company ("Common Share") and one Common Share purchase warrant (a "Warrant"). Each Warrant will entitle the holder to acquire one Common Share (each, a "Warrant Share") at an exercise price of $0.05 per Warrant Share until 4:30 pm (Pacific Standard time) on that date that is 60 months from the closing date of the Offering (the "Expiry Time").

Closing of the Offering is expected to occur on or before March 31, 2026 (the "Closing Date"). The Offering is subject to all customary approvals. Proceeds of the Offering will be used to fund the Company's follow on exploration work at the Company's portfolio of mineral properties and in particular Melba and Drayton-Black Lake based on recent exploration successes. The securities issued pursuant to the Offering will be subject to a four month hold period under applicable securities laws. In connection with the Offering, certain finders may receive a cash fee and/or nontransferable finder warrants.

A Finder's Fee equal to 7% cash and compensation unit warrants ("Compensation Unit Warrants") equal to 7% of the gross proceeds of the sale of FT Shares and Units, as applicable, issued pursuant to the Offering may be payable on certain orders in accordance with CSE rules. Each Compensation Unit Warrant will entitle the holder to acquire one Common Share and one Warrant of the Company at an exercise price of $0.05, for a period of 60 months following the Closing Date.

A Finder's Fee equal to 1.0% cash compensation on the number of Units or FT Shares, as applicable, issued pursuant to a President's list the Offering may be payable on certain orders in accordance with CSE rules.

"Heritage Mining Ltd. has secured lead orders totaling C$460,000 from insiders, institutions, advisors, consultants, and existing shareholders. We are grateful for the continued support of existing stakeholders and look forward to closing the financing later this month." Commented Peter Schloo, President, CEO, and Director.
