"We are very pleased to welcome Mr. Vazquez to the leadership team at Defiance.

SHARES FOR SERVICES
The Company previously entered into a non-arm's length administrative services agreement dated May 1, 2023 (the "Agreement"), for services provided by an officer of the Company. As part of the consideration payable by the Company under the Agreement, the Company has agreed to issue that number of Common Shares equal to $1,330 per month (the "Service Shares"), to be issued on a semi-annual basis and pursuant to the policies of the TSX Venture Exchange (the "TSXV"). The Agreement was for a term of three months and has automatically renewed in accordance with its terms, terminable by either party providing 30 days' notice of such termination.

The deemed value of the Service Shares to be issued for a particular month, is to be the closing price of the Company's shares on the last trading day of the month.

For services rendered under the Agreement between the period of July 1, 2024 to December 31, 2024, the Company has issued 33,448 Common Shares at a weighted average price of $0.244 per Common Share, extinguishing the accrued debt under the Agreement of $7,980. The transaction was subject to the approval of the TSXV.

The Service Shares issued are subject to a four month hold period, which will expire on a date that is four months and one day from the date of issuance.

No new insiders will be created, nor will any change of control occur, as a result of the issuance of the Service Shares.

As certain insiders are party to the Agreement, it may be considered a "related party transaction" under Multilateral Instrument 61-101 Protection of Minority Security Holders In Special Transactions ("MI 61-101") and the TSXV. The Company is relying on the exemptions from the formal valuation and the minority shareholder approval requirements of MI-61-101 contained in section 5.5 (a) and Section 5.7 (1)(a) as the fair market value of the common shares being issued to insiders in connection with the Service Shares does not exceed 25% of the market capitalization of the Company, as determined in accordance with MI 61-101.
