Why consider an exploration joint venture in Montana at Basin Gulch?
Basin Gulch combines a large amount of existing data with a lot of untested ground. Lannister Mining reports the gold and silver are hosted in oxides close to surface, which the company says implies significant mine design optimization flexibility. Several highlighted historical intercepts start at surface, including 0.66 g/t Au over 326 meters and 3.2 g/t Au over 72 meters.
The property sits mostly on patented land, with a core of patented claims surrounded by unpatented claims, and has year-round access from Philipsburg on paved and well-maintained gravel roads. Montana, the Treasure State, has a mining history that reaches back to the 1852 gold discovery at Gold Creek near Garrison.
