The Basin Gulch Property: gold and silver exploration in west-central Montana

The Basin Gulch Property is Lannister Mining's gold and silver exploration project in the Philipsburg Mining District of west-central Montana.

The Lannister Mining property covers 1,107 hectares, with 11 patented mining claims at its core surrounded by 53 unpatented claims. More than 320 historical drill holes have tested oxide-hosted mineralization that remains open at depth and along strike, while about two-thirds of the ground is still unexplored.

Where is the Basin Gulch Property, and how do you reach it?

Basin Gulch lies in the historic Philipsburg Mining District of west-central Montana. It has year-round access from the town of Philipsburg on paved and well-maintained gravel roads, and it is about one hour from Butte. Year-round access allows exploration work outside a short summer field season.

Property profile

Land, geology, access and upside

Land package and tenure

The Basin Gulch land package totals 1,107 hectares. At its center is a core of 11 patented mining claims, surrounded by 53 unpatented mining claims. Lannister Mining describes this as a large, consolidated land package with multiple high priority targets near the historic resource.

Basin Gulch is primarily on patented land. In the US, a patented claim is land where federal title has passed to the holder, while an unpatented claim grants mineral rights on public land. A patented core can simplify land access for exploration, though every program still follows state and federal rules.

Geology and mineralization

Gold and silver mineralization at Basin Gulch is hosted in oxides and sits near surface. Lannister Mining reports high-grade gold and silver mineralization near surface and says this implies significant flexibility in future mine design optimization.

The mineralization is open in multiple directions and at depth. Historical intercepts include 1.8 g/t Au over 162 meters from surface, and trench sampling returned silver alongside gold, such as 5 g/t Au and 54 g/t Ag over 34 meters. See all drilling highlights.

Access and setting

The property has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and is about one hour from Butte. Lannister Mining describes the site as accessible and open for business.

Basin Gulch sits in the heart of the historic Philipsburg Mining District, which led the original US silver boom in the late 1800s. The company describes the district as a safe jurisdiction, with a long record of mining activity around it.

Exploration upside

About two-thirds of the Basin Gulch Property is still unexplored. The known mineralization is open at depth and along strike, and the wider property is untested regionally.

Lannister Mining says the property has potential to host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical intercepts. Future drilling will also concentrate on additional mineralized target areas within the property, which is where exploration partners can add the most new information.

Montana

A property in the Treasure State

Montana is known as the Treasure State because of its vast mineral wealth and a history built on mining, and the industry continues to play an active role in the state economy. The first gold discovery in what was then the Montana territory came in 1852 at Gold Creek, near present-day Garrison.

Since then silver, copper, nickel and platinum have all been discovered and mined in the state, and Montana is home to large-scale producers in operation today. For a closer look at the US context, read about mineral exploration companies in the USA.

Common questions

Short answers here. The full mineral exploration FAQ covers more.

Where is the Basin Gulch Property?: The Basin Gulch Property is in west-central Montana, in the historic Philipsburg Mining District. It has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and sits about one hour from Butte. The district led the original US silver boom in the late 1800s.
How large is the Basin Gulch Property?: The total land package covers 1,107 hectares. It is made up of 11 patented mining claims at its core, surrounded by 53 unpatented mining claims. Lannister Mining reports that about two-thirds of the property is still unexplored, with multiple high priority targets near the historic resource.
What is the difference between patented and unpatented mining claims?: A patented claim is land where the US federal government has transferred title to the holder, while an unpatented claim grants mineral rights on public land without land ownership. Basin Gulch is primarily on patented land, with 11 patented claims at its core. The Bureau of Land Management can confirm how specific claim rules apply.
What does oxide hosted mean for a gold project?: Oxide hosted means the mineralization sits in rock that has been weathered and oxidized, usually near surface. In the industry, oxide gold is often simpler to process than sulfide-hosted gold, which can shape project design. Basin Gulch is described as oxide hosted and near surface. Processing outcomes depend on future metallurgical testing.
How much of Basin Gulch has been explored?: About one-third. Lannister Mining reports that two-thirds of the Basin Gulch Property is still unexplored. The mineralization is described as open at depth and along strike, and the wider property is untested regionally, which is why future drilling will also target additional mineralized areas.
How do you get to the Basin Gulch Property?: Basin Gulch has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads. The property is about one hour from Butte, Montana. Year-round access matters for exploration because it can allow drilling and fieldwork outside a short summer season.
