The Basin Gulch gold and silver property

Last updated: November 2026

Basin Gulch is a gold and silver exploration property in west-central Montana, explored by Lannister Mining. It is primarily on patented land, hosted in oxides, and has seen more than 320 historical drill holes, with mineralization open at depth, along strike and untested regionally.

Where is the Basin Gulch property and how do you get there?

Basin Gulch sits in the historic Philipsburg Mining District of west-central Montana. The property has year-round access from Philipsburg, Montana on paved and well-maintained gravel roads, and it is only one hour from Butte.

That access matters for an exploration company: crews, drill rigs and samples can move in every season, which supports a steady work program as Lannister Mining builds toward a maiden mineral resource estimate.

What Basin Gulch is

Basin Gulch is the single project of Lannister Mining: a consolidated land package that combines a core of patented mining claims with surrounding unpatented claims. The near-surface gold and silver mineralization is hosted in oxides, and the company describes it as offering significant implied mine design optimization flexibility.

The company states the property has not been mined out and has potential to host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical drill intercepts.

The land package in numbers

11 patented claims
53 unpatented claims
1,107 hectares in total
320+ historical drill holes
About two-thirds of the property still unexplored
1 hour by road from Butte, Montana

Open at depth, along strike and untested regionally.

What is the exploration upside at Basin Gulch?

With about two-thirds of the Basin Gulch property still unexplored, the company sees substantial exploration upside. The known mineralization is open in multiple directions and at depth, and Lannister Mining reports multiple high priority targets near the historic resource.

Future drilling will concentrate on additional mineralized target areas within the property, while historical drilling and new work programs will feed a future maiden mineral resource estimate. See the Basin Gulch historical drilling results for the intercepts behind this view.

Why does patented land matter?

In general, patented mining claims are privately held land where title has passed from the federal government to the claim holder, while unpatented claims carry mineral rights on public land. Basin Gulch is primarily on patented land, with a patented core surrounded by unpatented claims.

Permitting and land rules vary by site, so the specific implications for Basin Gulch are best confirmed in the company technical disclosures and the Bureau of Land Management guide to mining claims.

Common questions

See all questions in the Lannister Mining FAQ

Where is the Basin Gulch property?: Basin Gulch is in west-central Montana, in the historic Philipsburg Mining District. It has year-round access from Philipsburg on paved and well-maintained gravel roads and is about one hour from Butte, Montana.
How large is the Basin Gulch land package?: The total land package covers 1,107 hectares made up of 11 patented claims and 53 unpatented claims. The property is underlain by a core of patented mining claims surrounded by unpatented claims, and the company reports multiple high priority targets near the historic resource.
What is the difference between patented and unpatented claims?: In general, a patented mining claim is land where the federal government has passed title to the claim holder, while an unpatented claim gives the right to explore and develop minerals on public land without owning the surface. Basin Gulch is primarily on patented land, with 11 patented and 53 unpatented claims.
How much of Basin Gulch is still unexplored?: About two-thirds of the Basin Gulch property is still unexplored, according to the company. Mineralization is described as open at depth, open along strike and untested regionally, which is why future drilling will also target additional mineralized areas within the property.
What does oxide hosted gold mean at Basin Gulch?: Oxide mineralization is rock that has been weathered near the surface, which often makes gold and silver easier to recover than in deeper sulfide rock. The company states that Basin Gulch mineralization is hosted in oxides and sits near surface, which it says offers mine design optimization flexibility.
Has Basin Gulch already been mined?: Lannister Mining states that Basin Gulch has not been mined out. The property has seen significant historical exploration work, including more than 320 drill holes, and about two-thirds of it is still unexplored.
