The TSX Venture Exchange has accepted for filing documentation relating to an arm's-length option agreement dated Nov. 11, 2025, and amended on Dec. 3, 2025, between Harfang Exploration Inc. and an arm's-length third party. Pursuant to the option agreement, Harfang optioned up to an 80-per-cent interest in the Egan property, located in Ontario, Canada.

Under the option agreement, the optionee will have the option to earn a 40-per-cent interest in the property over a two-year period, in consideration of $1.5-million in exploration expenditures before the second anniversary of the effective date and $100,000 in payments ($50,000 on the effective date and $50,000 within five business days of the first anniversary date of the effective date), half in cash and half in the optionee's common shares at a minimum price of 6.4 cents per share.

Following the completion of the first option and upon the optionee's election to proceed with the second option described below, Harfang may elect to convert the optionee's remaining obligations to a 51-per-cent/ 49-per-cent joint venture in favour of the optionee.
