MASIVO SILVER UPDATE

Masivo Silver Corp. has provided the following corporate update.

Masivo continues to build momentum around the Boston mine in Elko county, Nevada. The company is finalizing assays for the remaining six holes of its phase 1 drill program. Results from the first drill hole confirm that Masivo's geological model and projected target zones are accurate. Hole No. 1 intersected two projected mineralized zones, including a significant interval of 55 feet (drilled width) grading 0.99 per cent copper, 1.52 grams per tonne gold and 30.35 g/t silver starting at 65 feet downhole. Assay results for the balance of the program are expected in October, 2025.

At the same time, Masivo is advancing toward the anticipated closing of the Cerro Colorado property acquisition in Sonora, where the project is already drill-permitted and ready for immediate mobilization of a drill program following financing and close. The company also maintains a $75,000 drill credit in Mexico, positioning it to launch work quickly and cost-effectively. Additional opportunities in the state of Sinaloa continue to be reviewed, further strengthening Masivo's growth pipeline of Silver assets.

Masivo also provides the following update on the status of its management cease trade order, issued on July 30, 2025, by the B.C. Securities Commission under National Policy 12-203. As previously announced, the company was unable to file its annual financial statements, management's discussion and analysis, and related certifications for the year ended March 31, 2025, by the July 29, 2025, deadline due to delays in obtaining financial information from its Mexican operations.

The financial statements have since been prepared, and the associated audit is under way. Masivo expects the audit to be completed, and the required filings submitted by Sept. 29, 2025. The MCTO will remain in effect until the filings are made or the order is otherwise revoked or varied.

The company confirms that it will continue to comply with the alternative information guidelines under NP 12-203 for as long as it remains in default. Masivo has not initiated any insolvency proceedings and has no undisclosed material information to report at this time.
