The project

The Basin Gulch gold-silver project

Basin Gulch is a gold and silver exploration property in west-central Montana with near-surface oxide mineralization, more than 320 historical drill holes, and two-thirds of its ground still unexplored.

Last updated: November 2026. Published by Lannister Mining.

Where is the Basin Gulch property and what is on it?

The Basin Gulch property is in the historic Philipsburg Mining District of west-central Montana, about one hour from Butte. Lannister Mining holds 11 patented and 53 unpatented claims covering 1,107 hectares there. The gold-silver mineralization is hosted in oxides near surface and is open at depth, along strike, and untested regionally.

Definition

What the Basin Gulch project is

The Basin Gulch project is Lannister Mining's gold and silver exploration property in west-central Montana. It is primarily on patented land, hosted in oxides, and has seen more than 320 historical drill holes. It has not been mined out.

Lannister Mining states that the property has potential to host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical drill intercepts. No current resource estimate is presented on this site.

Land package

Patented core, unpatented surround

The property is underlain by a core of patented mining claims surrounded by unpatented mining claims. In total, the consolidated land package includes 11 patented claims and 53 unpatented claims across 1,107 hectares.

Lannister Mining describes the package as large and highly prospective, with multiple high-priority targets near the historic resource area. Patented claims are privately held land, which the company highlights as a feature of the property.

Open at depth, along strike and untested regionally.

Access

How do you reach Basin Gulch?

Basin Gulch has year-round access from Philipsburg, Montana on paved and well-maintained gravel roads, and it is only one hour from Butte. For an exploration company, that matters: drill crews, geologists, and visiting partners can work the property through every season rather than inside a short summer window.

Philipsburg sits at the heart of the historic Philipsburg Mining District, which led the US original silver boom in the late 1800s. Read more about mineral exploration in Montana.

Exploration upside

Why is two-thirds unexplored ground important?

With two-thirds of the Basin Gulch property still unexplored, Lannister Mining sees substantial exploration upside. Known mineralization is open in multiple directions and at depth, so drilling can test both the edges of the historical work and entirely new targets.

Future drilling will concentrate on additional mineralized target areas within the property, alongside confirmation of historical intercepts. The full set of historical highlights is on the Basin Gulch drilling page.

How big is the Basin Gulch land package?
The Basin Gulch land package covers 1,107 hectares made up of 11 patented claims and 53 unpatented claims. A core of patented mining claims is surrounded by unpatented claims. Lannister Mining describes multiple high-priority targets near the historic resource area, and roughly two-thirds of the property remains unexplored.See this answer in the FAQ
What kind of mineralization is at Basin Gulch?
Basin Gulch hosts near-surface gold-silver mineralization in oxides. The company describes it as open at depth, open along strike, and untested regionally. Several historical intercepts begin at surface, including 1.8 g/t gold over 162 meters, which the company says gives significant implied mine design optimization flexibility.See this answer in the FAQ
What are patented and unpatented mining claims?
A patented mining claim is private land where the owner holds title to the surface and the minerals. An unpatented claim gives the holder the right to explore and develop minerals on federal land, subject to annual maintenance requirements. Basin Gulch combines 11 patented claims at its core with 53 unpatented claims around them.See this answer in the FAQ
How much of Basin Gulch is unexplored?
About two-thirds of the Basin Gulch property is still unexplored, according to Lannister Mining. The mineralization is described as open at depth and along strike and untested regionally, so future drilling is planned to concentrate on additional mineralized target areas within the property as well as on confirming historical results.See this answer in the FAQ
How do you get to Basin Gulch?
Basin Gulch has year-round access from Philipsburg, Montana, using paved and well-maintained gravel roads, and it is about one hour from Butte.
