MASIVO SILVER SECURES CERRO COLORADO PROPERTY ACCESS AGREEMENT

Masivo Silver Corp. has executed a 10-year land-use and access agreement for the private property where the Cerro Colorado project in Sonora, Mexico, is located. The final agreement was completed on Oct. 29, 2025.

Under the terms of the agreement, Masivo will make a flat annual payment of approximately $60 (U.S.). The agreement grants the company full rights to rehabilitate or construct access roads, establish drill pads and core storage facilities, set up temporary camps and offices, and conduct drilling, sampling and mineral extraction activities -- subject to the required environmental permits. The land-use agreement is a prerequisite to obtaining these permits and ensures compliance with local and federal environmental regulations.

The agreement also provides Masivo with the right to extend or amend the access term in the future by mutual consent with the landowner. The company is currently advancing the permitting process for drilling and drill pad construction as it prepares for a planned phase I drill program.

The Cerro Colorado project is located approximately 28 kilometres northeast of Alamos, Sonora, and about 11 kilometres north of the Piedras Verdes open-pit copper mine, one of Mexico's largest copper operations. The project comprises two mineral concessions totalling 2,649 hectares (6,542 acres) and is considered highly prospective for both precious and base metals.

Historical work at Cerro Colorado reported silver values up to 2,200 grams per tonne silver and gold values up to 4.57 grams per tonne gold from underground workings documented in 1972. More recent sampling has confirmed strong silver, gold, copper, lead and zinc mineralization along principal structural zones.

Masivo's geological team -- led by Jorge Rafael Gallardo, in collaboration with Mark Bailey, PGeo, and Brian Brewer, PGeo -- is finalizing the design of an initial eight-hole drill program to test the along-strike and down-dip extensions of the main mineralized zones identified from surface mapping and historical data.

David Coburn, chief executive officer of Masivo Silver, commented: "Securing long-term access to the Cerro Colorado property represents an important milestone for Masivo and provides the stability necessary to advance our exploration program in Sonora. We greatly appreciate the landowner's co-operation and look forward to a strong, long-term partnership. Establishing this agreement, which is required for permitting, underscores our commitment to responsible and compliant project development."
