The Basin Gulch Property

The Basin Gulch Property: gold and silver near Philipsburg, Montana

Published by Lannister Mining Last updated November 2026

The Basin Gulch Property is a 1,107 hectare gold and silver exploration property in west-central Montana, held by Lannister Mining.

Lannister Mining describes Basin Gulch as primarily on patented land, hosted in oxides, and tested by more than 320 historical drill holes. Mineralization is open at depth, along strike, and untested regionally, and two thirds of the property is still unexplored, which leaves room for both confirmation drilling and new discoveries.

What makes Basin Gulch stand out as an exploration property?

Basin Gulch stands out because it pairs a large historical dataset with a lot of untested ground. More than 320 drill holes have already sampled the property, yet Lannister Mining states that two thirds of it remains unexplored.

The company also describes the asset as one that has not been mined out, with high grade gold and silver mineralization near surface and significant implied mine design optimization flexibility.

What the land package includes

The Basin Gulch land package includes 11 patented claims and 53 unpatented claims, for a total of 1,107 hectares. The property is underlain by a core of patented mining claims surrounded by unpatented mining claims.

Patented claims are private land, while unpatented claims carry mineral rights on federal land. Having the core of the property on patented land is a point Lannister Mining highlights, and the company describes multiple high priority targets near the historic resource area.

Basin Gulch Property profile, as published by Lannister Mining
Feature	Basin Gulch detail	What it means for exploration
Location	Philipsburg Mining District, west-central Montana	Historic district with prior mining activity
Access	Year-round from Philipsburg; one hour from Butte	Programs are not limited to a short season
Land status	Patented core surrounded by unpatented claims	Private land at the center of the property
Mineralization	Gold and silver hosted in oxides, near surface	Shallow targets for confirmation drilling
Open directions	Open at depth, along strike, untested regionally	Room to grow beyond known intercepts
Resource status	Future Maiden Mineral Resource Estimate planned	No current resource; drilling comes first

Where is the exploration upside?

With two thirds of the property still unexplored, Lannister Mining sees substantial exploration upside. Future drilling is planned to concentrate on additional mineralized target areas within the property, while expansion and confirmation drilling targets historical intercepts.

Lannister Mining states the property has potential to host a significant Maiden Mineral Resource Estimate after that drilling. That is a forward-looking goal, not a current resource.

Details of what earlier drilling found are on the Basin Gulch historical drilling results page, and the original property page is on the Lannister Mining website.

Common questions

Short answers from the full gold exploration FAQ.

Where is the Basin Gulch Property?

The Basin Gulch Property is in west-central Montana, in the historic Philipsburg Mining District. Lannister Mining states it has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and it is about one hour from Butte. That access matters for drilling programs, because crews and equipment can reach the site through the seasons.

How many claims are in the Basin Gulch Property?

The Basin Gulch land package includes 11 patented claims and 53 unpatented claims, covering 1,107 hectares, according to Lannister Mining. The property is built around a core of patented mining claims surrounded by unpatented mining claims. Lannister Mining also describes multiple high priority targets near the historic resource area.

What is the difference between patented and unpatented mining claims?

A patented claim is private land where the federal government has transferred title, while an unpatented claim grants mineral rights on federal land without surface title. Unpatented claims require ongoing filings and fees with the Bureau of Land Management. Basin Gulch is primarily on patented land, with unpatented claims surrounding that core.

How much of Basin Gulch has been explored?

Lannister Mining states that two thirds of the Basin Gulch Property is still unexplored. The mineralization is described as open at depth, along strike, and untested regionally. Historical work concentrated on part of the land package, which leaves room for new target testing alongside confirmation drilling.

What does oxide-hosted gold mean?

Oxide-hosted gold sits in rock that has been weathered and oxidized near the surface. Oxide material is often simpler to process than unoxidized sulfide rock, although the metallurgy of every deposit has to be tested. Lannister Mining states that Basin Gulch mineralization is hosted in oxides and sits near surface.

Does Basin Gulch have a mineral resource estimate?

Not yet. Lannister Mining states that historical drilling and new work programs will be used in a future Maiden Mineral Resource Estimate, after expansion and confirmation drilling of historical drill intercepts. A maiden estimate is the first formal resource reported for a project under a recognized disclosure standard.
