What is the Basin Gulch Property?

The Basin Gulch Property is Lannister Mining's 1,107-hectare gold and silver exploration project in west-central Montana, hosted in near-surface oxides and tested by more than 320 historical drill holes.

Basin Gulch is primarily on patented land and open at depth, along strike and untested regionally. Lannister Mining believes it has the potential to host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling of historical drill intercepts.

Basin Gulch at a glance

The Basin Gulch Property, explored by Lannister Mining, covers 1,107 hectares made up of 11 patented and 53 unpatented mining claims. A core of patented claims sits at the centre, surrounded by unpatented claims. More than 320 historical drill holes have tested the area near the historic resource, while roughly two-thirds of the property is still unexplored.

Gold and silver mineralization is hosted in oxides near surface. The company describes the mineralization as open in multiple directions and at depth, with multiple high priority targets near the historic resource.

Why is two-thirds of Basin Gulch still unexplored?

Historical work at Basin Gulch concentrated near the historic resource, leaving most of the land package untested. That is where Lannister Mining sees exploration upside: the mineralization is open along strike and at depth, and the wider property is untested regionally.

Easy, year-round access from Philipsburg on paved and well-maintained gravel roads, and a one hour drive to Butte, make the site practical for field programs through the year.

Future drilling will concentrate on additional mineralized target areas within the property, alongside confirmation of historical drilling. See the Basin Gulch historical drilling results for the intercepts the company highlights.

What does near-surface oxide mean for a gold and silver project?

Oxide mineralization forms where weathering has altered rock close to surface. Lannister Mining describes the gold and silver mineralization at Basin Gulch as high grade and near surface, and says this implies significant flexibility in future mine design optimization. Several historical drill intersections begin at surface, including 1.8 g/t gold over 162 meters and 3.2 g/t gold over 72 meters.

This property sits within a state with a long mining record. Read more about gold and silver exploration in Montana and the Philipsburg district, or return to the Lannister Mining mineral exploration company overview.
