NEVADA

This  highly prospective silver-gold-copper project in Elko County,  Nevada,  the historic Boston Mine.
 

Highlights
 

Boston Mine - located in the eastern portion of the claim group, was developed in 1910 with a 190-foot shaft and levels at 90 and 190 feet, with 360 feet of drifting on both levels. 
 

●     High-Grade History - The mine reported shipments of high-grade silver, gold and copper from a zone that varied in width from six to 40 feet with grades up to 226 grams per tonne (“g/t”) silver, 9 g/t gold and 6.8 per cent copper, with localized zones of up to 2,880 g/t silver, 25.7 g/t gold and 3.2 per cent copper. 
●     Exploration Upside - Since the mine's closure at the onset of the Second World War, the mine was held in private hands, with activity limited to, sporadic surface exploration, sampling on the 90-foot level, and limited surface drilling.
 

JP Claim Block (west section) - Rock and soil geochemistry have defined silver, gold and copper mineralization similar to that in the Boston Mine area, for greater than one kilometre of strike length.
 

●     High-Grade Samples - Numerous grab samples of contact-related skarn mineralization in this area have returned values from 35 to 170 g/t silver, one to 10 g/t gold and 1 to 3 per cent copper.
●     Undeveloped Potential - Despite high-grade showings, as well as the presence of favourable geology and extensive alteration, there has been no systematic evaluation of surface showings or drilling to test continuity and extensions at depth.
David Coburn, Masivo Silver Corp. CEO, stated “We are very happy to have finalized this option agreement and are excited to be implementing our exploration plan in the historically prolific Boston mining camp located in Nevada, one of the top mining jurisdictions in the world.”  
 

Geology Overview
The property covers about nine kilometres of prospective metamorphosed limestones containing silver, gold and copper stratabound skarn mineralization marginal to the contact of a Jurassic aged granodiorite intrusion. Mineralization consists of bornite, chalcopyrite and diginite with silver and gold in calc-silicate hornfels adjacent to faults and altered porphyry dikes, as well as in stratiform replacement of favourable horizons adjacent to the granodiorite contact.
