Masivo Update News Release

Vancouver, British Columbia, September, 25 2025 - Masivo Silver Corp. ("Masivo" or the "Company") (TSXV: MASS) (OTC: GNYPF) is pleased to announce the following update: Per successful meetings this week in Mexico, Masivo continues advancing towards closing on several mining properties including the Cerro Colorado property in Sonora.

Masivo is providing this bi-weekly update on the status of its management cease trade order issued on July 30, 2025 (the "MCTO"), by its principal regulator, the British Columbia Securities Commission (the "BCSC"), under National Policy 12-203 Management Cease Trade Orders ("NP 12-203"). The Company announced on July 28, 2025 (the "Default Announcement"), that it expected to be unable to file its annual financial statements, management's discussion and analysis and related officer certifications for the financial year ended March 31, 2025 (collectively, the "Annual Filings") by the filing deadline of July 29, 2025 (the "Filing Deadline").

In connection with the anticipated delay, the Company has applied to the applicable Canadian securities regulators requesting that a voluntary management cease trade order ("MCTO") be imposed to restrict trading in the Company's securities by insiders of the Company, as opposed to an issuer cease trade order, which would restrict al trading in the Company's securities. If granted, the MCTO will be in effect until the Required Filings are filed or until it is revoked or varied.

The delay in preparing the Annual FS and Annual MD&A was due in part to difficulties in obtaining financial information from its Mexican operations. They have now been prepared and the associated audit work is in progress, but the Company is unable to complete and file such materials on time. The Company expects the audit to be completed by September 30, 2025.

The Company confirms that it intends to satisfy the provisions of the alternative information guidelines described in section 43. and 4. of National Policy 12-203 - Management Cease Trade Orders for as long as it remains in default of the requirement to file the Required Filings on or before July 29, 2025. The Company has not taken any steps towards any insolvency proceeding and the Company has no material information to release to the public. The Company has made the foregoing representations in accordance with the requirements of applicable securities laws.
