The Basin Gulch Property in Montana

Basin Gulch is a gold and silver exploration property near Philipsburg, Montana, made up of 11 patented and 53 unpatented claims over 1,107 hectares.

Lannister Mining explores Basin Gulch for gold and silver hosted in oxides near surface. The property has seen more than 320 historical drill holes, yet about two-thirds of it remains unexplored, and the known mineralization is open at depth and along strike.

Where exactly is Basin Gulch?

Basin Gulch lies in the heart of the historic Philipsburg Mining District in west-central Montana. The property has year-round access from Philipsburg on paved and well-maintained gravel roads, and it is about one hour from Butte. For drill crews and partners, that means programs can be planned without a short seasonal window.

The Philipsburg district led the original US silver boom in the late 1800s. Lannister Mining describes the setting as a safe jurisdiction with a mining history that continues to play an active role in the Montana economy today.

What is a patented mining claim?

A patented mining claim is land where the US federal government has transferred full title to a private owner, covering both surface and minerals. At Basin Gulch, a core of 11 patented claims is surrounded by 53 unpatented claims, which give the right to explore and develop minerals on federal land while the government keeps title.

Lannister Mining states that the known mineralization is primarily on patented land. The Bureau of Land Management explains how unpatented claims are held and maintained.

Why oxide-hosted, near-surface mineralization matters

Lannister Mining describes Basin Gulch as high grade gold and silver mineralization, near surface and hosted in oxides, and says this gives significant implied mine design optimization flexibility. Mineralization close to surface can be reached with shorter drill holes, and oxidized rock is often simpler to test.

As with any exploration project, processing options still need to be confirmed through metallurgical testwork during later technical studies.

Exploration upside on unexplored ground

With about two-thirds of Basin Gulch still unexplored, Lannister Mining sees substantial room to find more. The company lists multiple high priority targets near the historic resource area, and states that the known mineralization is open at depth, along strike and untested regionally.

That combination, a drilled core plus a large untested footprint, is why the company plans both confirmation drilling and drilling on new targets. Read the exploration plans or review the historical drilling results.

Montana: the Treasure State

Montana earned the name Treasure State through its mineral wealth and mining history. The first gold discovery in the Montana territory was in 1852 at Gold Creek, near present-day Garrison. Since then silver, copper, nickel and platinum have all been discovered and mined, and Lannister Mining notes that large-scale producers operate in the state today.

What is the difference between patented and unpatented mining claims?

An unpatented claim gives the right to explore and develop minerals on federal land while the government keeps title, and it is maintained with annual filings and fees. The Bureau of Land Management can confirm current rules.
How much of the Basin Gulch Property has been explored?
Lannister Mining states that about two-thirds of the Basin Gulch Property is still unexplored. The company says the known gold and silver mineralization is open at depth, open along strike and untested regionally, which is why future drilling is planned both around historical intercepts and on additional target areas within the property.
What type of gold mineralization is at Basin Gulch?
Lannister Mining describes Basin Gulch as gold and silver mineralization hosted in oxides, near surface, and primarily on patented land. The company says this gives significant implied mine design optimization flexibility. Any processing route would still need confirmation through metallurgical testwork during later technical studies, as with any exploration project.
Why does the Philipsburg Mining District matter?
The Philipsburg Mining District led the original US silver boom in the late 1800s, so the area has a long mining history and established road access. Montana is known as the Treasure State, and the first gold discovery in the Montana territory was in 1852 at Gold Creek, near present-day Garrison. Lannister Mining calls it a safe jurisdiction.
Can the Basin Gulch Property be reached year-round?
Yes. Lannister Mining states the property has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and that it sits about one hour from Butte. Year-round access matters to exploration partners because it affects when drill programs, sampling and site visits can be scheduled.
