Nevada's Boston Mine Joins Masivo Silver's Exploration Portfolio Through 100% Earn-In Agreement

Masivo Silver Corp. (TSXV: MASS) has secured a major milestone in its precious metals strategy by finalizing a binding accord for full ownership rights to a silver-gold-copper project in Elko County, Nevada—a region synonymous with North American mineral wealth. The 543-hectare claim group encompasses 65 unpatented claims and one patented claim, anchored by the historic Boston Mine, establishing a significant foundation for the company’s Nevada operations.

The Boston Mine: A Storied Asset with Proven Reserves

At the heart of the project lies the Boston Mine, an underground operation established over a century ago. Early development efforts reached depths of 190 feet, with two working levels connected by 360 feet of horizontal drifting. The mine’s production history tells a compelling story: historical shipments yielded impressive grades averaging 226 g/t silver, 9 g/t gold, and 6.8% copper from zones ranging 6 to 40 feet in width. In particularly rich sections, samples exceeded 2,880 g/t silver, 25.7 g/t gold, and 32% copper—grades that highlight the project’s inherent quality.

The mine’s closure during the Second World War left the property in private ownership with minimal systematic exploration for decades. This dormancy presents a dual opportunity: the proven historical resource coupled with unexplored adjacent mineralization creates substantial upside for modern exploration techniques.

Western Extension Shows High-Grade Promise

The JP Claim Block, encompassing the western section of the property, demonstrates geological continuity with the Boston Mine across more than one kilometre of strike length. Rock and soil geochemistry surveys have identified silver, gold, and copper mineralization patterns consistent with the main mine area. Surface samples from contact-related skarn deposits have yielded assays ranging from 35 to 170 g/t silver, 1 to 10 g/t gold, and 1 to 3% copper.

Despite these encouraging surface showings and the presence of favorable geological indicators and extensive alteration zones, the western block remains largely untested through systematic drilling programs, creating a clear pathway for discovery.

Investment Framework and Milestones

To acquire full ownership, Masivo has committed to a structured four-year program. The financial commitment totals US$450,000 in cash payments, paired with the issuance of eight million shares distributed across annual milestones. In year one, the company will pay US$20,000, issue one million shares, and grant one million warrants at $0.15. Subsequent years involve escalating cash contributions ($25,000, $30,000, $35,000, and $340,000) paired with corresponding share issuances of 1.5, 1, 2, and 2.5 million shares respectively.

Beyond share consideration, Masivo must invest US$1 million in exploration and development activities over the four-year period, with annual spending increasing from $100,000 to $400,000. The underlying project will carry a 2% net smelter return royalty, with a buydown option available at $500,000 per 0.5% reduction.

Geological Foundation and Mineralization Style

The property straddles approximately nine kilometres of metamorphosed limestone sequences hosting stratabound skarn-style silver, gold, and copper mineralization. The mineralizing system relates to a Jurassic-aged granodiorite intrusion, with ore minerals including bornite, chalcopyrite, and digenite. Silver and gold enrichment occurs within calc-silicate hornfels adjacent to fault zones and altered porphyry dikes, as well as in stratiform replacement deposits along favorable horizons near the granodiorite contact.

This geological architecture indicates a mature mineralized system with multiple styles of precious metal concentration, suggesting exploration potential extends beyond the historically worked Boston Mine.

Strategic Positioning and Next Steps

David Coburn, Chief Executive Officer of Masivo Silver Corp., emphasized the significance of the acquisition: “This agreement marks an important expansion for our company, positioning us within one of North America’s premier mining jurisdictions and a historically productive silver-gold district.”

The transaction requires acceptance from the TSX Venture Exchange. Additionally, Tom Quigley has consented to join Masivo’s board upon transaction closing. Brian Brewer, M.Sc. CPG (#11508), serves as the qualified person for this project, having reviewed and approved technical disclosures.

Masivo Silver operates as a silver and gold exploration and development company with a focus on Mexico’s Sierra Madre Occidental Trend, where the company holds approximately 14,000 hectares. The company maintains ore processing infrastructure on its El Colomo property capable of handling 300 tons daily, positioning it for potential transition from pure-play explorer to mineral producer.
