Basin Gulch is a 1,107-hectare gold and silver exploration property in west-central Montana with more than 320 historical drill holes.
Lannister Mining describes Basin Gulch as primarily on patented land, hosted in oxides, open at depth and along strike, and untested regionally. The company says the property has potential to host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling of historical drill intercepts.

Historical drilling and trenching at Basin Gulch found gold and silver mineralization, including long intervals starting at surface. The strongest long intercept listed is 1.8 g/t Au over 162 meters from surface. These are historical results reported by Lannister Mining and are not a mineral resource.

Context
Land package
Basin Gulch is underlain by a core of patented mining claims surrounded by unpatented mining claims: 11 patented and 53 unpatented, 1,107 hectares in total. Lannister Mining reports multiple high priority targets near the historic resource and states that two-thirds of the property is still unexplored, with future drilling to focus on additional mineralized target areas.
District
The property sits in the historic Philipsburg Mining District, which Lannister Mining notes led the original US silver boom in the late 1800s. Montana is known as the Treasure State; the first gold discovery in the Montana territory was in 1852 at Gold Creek, near present-day Garrison. Access is year-round from Philipsburg, MT on paved and well-maintained gravel roads.

More in the FAQNear-surface oxide gold is gold hosted in rock that has been weathered and oxidized close to the surface. Oxide material is often simpler to process than deeper sulphide rock, and shallow mineralization can suit open pit designs. Lannister Mining cites significant implied mine design optimization flexibility at Basin Gulch.
More in the FAQLannister Mining states that two-thirds of the Basin Gulch Property is still unexplored. It also says mineralization is open at depth, along strike and untested regionally, which is why future drilling will target additional mineralized areas within the property.
