The acquisition of New Boston in August, 2017, augments the Company’s copper-gold exploration strategy in Nevada. The company will leverage its experience and focus on porphyry systems in western Nevada over the past 5 years to explore and evaluate the copper-moly porphyry system and skarn mineralization at New Boston; proximity to the Company’s nearby Yellow Peak property has particular technical relevance.
New Boston occurs within the southeastern part of the Walker Lane belt in west-central Nevada. It is located between the past-producing Yerington porphyry copper camp located approximately 100 km to the northwest, and the late Cretaceous Hall moly-copper deposit located approximately 100 kilometres to the southeast.
The New Boston porphyry-skarn mineral system is well exposed, with copper sulfide, copper oxide and sheeted quartz veins exposed at-surface over a 5 kilometre trend, hosted in both intermediate intrusive rocks, and in sedimentary country rock. Artisanal mining at the turn of the century focused on high grade W-Mo-Cu-Ag skarns at the west end of the system at the Blue Ribbon Mine. Deep copper-moly’ porphyry mineralization was the exploration focus of major mining companies in the 1960’s and 1970’s in the central and eastern part of the system, named New Boston, followed by drilling for shallow, skarn-related tungsten mineralization at the Jeep Mine in the center of the system.
As evident in the distribution of historic drill holes on the property, VR will focus on well mapped but less explored sheeted vein and hydrothermal breccia systems in the eastern-most part of the system where weathering has exposed the deeper parts of the New Boston system.
