Masivo Silver drills polymetallic mineralization at Cerro Colorado, Sonora

Vancouver, British Columbia--(Newsfile Corp. - September 29, 2026) - Masivo Silver Corp. (TSXV: MASS) (OTC Pink: GNYPF) ("Masivo" or the "Company") is pleased to report encouraging analytical results from Drill Hole CC-26-001 , the first drill hole completed as part of the Company's current exploration program at its Cerro Colorado Project in Sonora, Mexico.

CC-26-001 intersected a broad polymetallic mineralized system , including 32.50 metres from 226.30 to 258.80 metres averaging 0.271% Zn, 7.0 g/t Ag, 0.141% Pb, 0.025% Cu and 0.01 g/t Au .

Higher in the hole, drilling also intersected 5.10 metres from 215.10 to 220.20 metres averaging 24.0 g/t Ag, 0.611% Zn, 0.121% Pb, 0.035% Cu and 0.024 g/t Au .

Importantly, CC-26-001 remained within the strongly altered and mineralized rhyolitic porphyry at the end of the hole. Drilling was terminated at 259.5 metres due to technical difficulties , rather than because the mineralized geological package had ended.

The bottom portion of the hole is particularly encouraging with assays of 15.6 g/t Ag, 0.433% Zn, 0.244% Pb and 0.051% Cu from 256.8 to 257.8 metres , followed by 29.4 g/t Ag, 0.568% Zn, 0.293% Pb and 0.164% Cu from 257.8 to 258.8 metres .

The Company believes the combination of the broad width of mineralization, strong alteration, persistent polymetallic signature and strengthening grades near the bottom of the hole provides compelling technical justification for follow-up drilling.

HIGHLIGHTS

Beginning at approximately 215 metres, the hole encountered increasing sericitic alteration accompanied by pyrite, sphalerite, galena, freibergite and locally chalcopyrite. From approximately 217 metres onward, geological logging records strong serici
