Vancouver, British Columbia--(Newsfile Corp. - December 22, 2025) - Masivo Silver Corp. (TSXV: MASS) (OTC Pink: GNYPF) ("Masivo" or the "Company") is pleased to provide an update on ongoing exploration and permitting activities at its Cerro Colorado Project, located in the State of Sonora, Mexico.

Permitting Progress

Masivo reports that it has submitted the required environmental permit applications to SEMARNAT (Secretaría de Medio Ambiente y Recursos Naturales) in support of its proposed exploration activities at the Cerro Colorado Project. These permit applications cover planned drilling, access preparation, and associated exploration infrastructure required for the Company's initial exploration phase.

The submission of the SEMARNAT permits represents a key milestone in advancing the Cerro Colorado Project toward active drilling and reflects the Company's commitment to conducting exploration activities in full compliance with Mexican environmental and regulatory standards.

Planned Phase 1 Drill Program - Targeting January 2026

Subject to the receipt of all necessary regulatory approvals, Masivo is targeting the commencement of its Phase 1 drill program in January 2026. The initial drill program is designed to test priority geological targets identified through historical data review, surface mapping, sampling, and prior exploration work completed on and around the property.

The Phase 1 program is expected to focus on confirming known mineralization and expanding upon zones of interest that demonstrate the potential for precious and base metal mineralization. Drill results from this phase will be used to refine geological models and guide future exploration and drilling programs.

Management Commentary

David Coburn, Chief Executive Officer of Masivo Silver Corp., commented:

"The submission of our SEMARNAT permits is a significant step forward for the Cerro Colorado Project. With land access secured and permitting now underway, we are positioning Masivo to move efficiently into drilling. Our team is working toward a January 2026 drill start, which we believe will be an important catalyst as we begin systematically testing the project's exploration potential."
