Heritage Mining Increases Private Placement Size, Plans OTCQX Listing

VANCOUVER, BC — March 26, 2026 — Leads & Copy —

Heritage Mining Ltd. (CSE:HML) (FRA:Y66) has announced it will increase the size of its previously announced non-brokered private placement due to strong market demand. The company now intends to issue up to approximately 18,750,000 units at a price of $0.04 per unit and 18,750,000 flow-through shares at a price of $0.04 per FT Share for gross proceeds of up to $1,500,000.

The company also plans to pursue a listing on the OTCQX Market in Q2 2026, responding to strong market demand from U.S. investors. The initiative is designed to broaden the company's investor base, increase liquidity, and enhance its visibility among North American investors. The company has started the required regulatory and administrative steps and engaged advisors. Heritage plans to commence trading on the OTCQX under a new ticker symbol to be announced prior to listing while continuing to trade on the Canadian Securities Exchange under the symbol “HML”.

Each flow-through share will qualify as a “flow-through share” as defined in subsection 66(15) of the Income Tax Act (Canada). Proceeds from the FT Shares will be used to incur eligible "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" related to the company's projects in Ontario, Canada. The company plans to incur qualifying expenditures on or before December 31, 2027, and renounce all the qualifying expenditures in favor 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 and one common share purchase warrant. Each warrant will entitle the holder to acquire one common share at an exercise price of $0.05 per warrant share until 4:30 pm (Pacific Standard time) on the date that is 60 months from the closing date of the offering.

The offering is expected to close on or before April 18, 2026, and is subject to all customary approvals. Proceeds will be used to fund follow-on exploration work at the company’s portfolio of mineral properties, especially Melba and Drayton-Black Lake. The securities issued will be subject to a four-month hold period under applicable securities laws. Certain finders may receive a cash fee and/or nontransferable finder warrants.

A finder’s fee equal to 7% cash and compensation unit warrants equal to 7% of the gross proceeds of the sale of FT Shares and Units, 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 $0.04 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 issued pursuant to a President’s list may be payable on certain orders in accordance with CSE rules.
