ARGENTUM ANNOUNCES LOAN

Argentum Silver Corp., on Sept. 15, 2025, issued an unsecured promissory note to an arm's-length lender of the company, for available proceeds to the company of $50,000. The loan shall be payable, at any time after the date of issuance, on demand by the lender and shall bear interest at 15 per cent per annum. The loan will be used for general working capital purposes. The note is intended to provide immediate capital to the company while it seeks additional sources of capital, which may include the future issuance of other debt or equity securities, including, without limitation, a formal credit facility, whether with the lender or otherwise, to meet the company's long-term capital needs.

In addition, the company confirms that its Cochavara mine 1 concession in La Libertad, northern Peru, has expired. The company confirms it no longer has any mineral property interests in Peru. The company's decision not to renew the validity of the property was made following a strategic review of the company's exploration priorities and capital allocation.

The company is actively reviewing new mineral exploration and development opportunities, including projects located in established silver districts, with the objective of securing a qualifying property that can deliver shareholder value. Until such time, the company will continue to operate with a disciplined cost structure while maintaining its listing in good standing on the TSX Venture Exchange.

There can be no assurance that the company will successfully identify or acquire new mineral assets, and the company will provide updates as material developments occur.
