Vancouver, British Columbia--(Newsfile Corp. - July 15, 2026) - Masivo Silver Corp. (TSXV: MASS) (OTC Pink: GNYPF) (FSE: R74) is pleased to report drill results from its Boston Mine Project in northeastern Nevada, confirming the continuation of high-grade gold, silver and copper mineralization beneath the historic underground workings. Seven drill holes were completed testing surface showings and high grade underground samples from the upper level of the mine.
Results include 5 ft. of 2.86g/t Au, 84.7g.t Ag, 2.67% Cu (6.39% CuEq) in a broader zone of 45 ft. of 1.73g/t Au, 34.7g/t Ag, and 1.14% Cu (3.25% CuEq) in drill hole BM21-01 and significant intercepts in step out drilling along the trend of underground development, as described below.
The Boston Mine Project hosts a compelling combination of historical production, underground development, strong geophysical targets and extensive exploration upside in one of the world's premier mining jurisdictions. Masivo CEO David Coburn stated:
"These drill results are an important step in demonstrating that the historic Boston Mine represents more than a small, isolated occurrence. The drilling has confirmed the continuation of high-grade gold, silver and copper mineralization beneath the historic workings while also supporting our belief that the mineralized system extends well beyond the original mine. We believe we are still in the early stages of unlocking the potential of what could prove to be a significant mineralized district."
BOSTON MINE HIGHLIGHTS
The historic Boston Mine was developed with a 190 ft. shaft and underground workings on two levels at 90 and 190 ft., and produced high-grade gold, silver and copper mineralization from both levels. Historic reports describe shipments with grades up to 6.8% Cu, 226 g/t Ag and 9 g/t Au. More recent channel sampling of the upper mine level has returned values up to 35.5g/t Au, 37.4g/t Ag, and 1.14% Cu. The lower mine level has not been accessed, and the first drilling program was directed at testing mineralization between the upper mine level and the lower mine level, as well as induced polarization anomalies adjacent to the mine development.
Results of the recent drill program and underground sampling are described and shown in the longitudinal section, plan view and tables below.
DRILLING DETAILS
BM21-01 was an undercut approximately 20 m below the mineralization exposed in the upper level adit. The hole returned two mineralized horizons shown below:
