Basin Gulch Property
Last updated: November 2026 · Published by Lannister Mining
Basin Gulch is a 1,107 hectare gold and silver oxide exploration property in west-central Montana, held by Lannister Mining and reached year-round from Philipsburg.
The Basin Gulch Property combines 11 patented and 53 unpatented mining claims, sits primarily on patented land, and has seen more than 320 historical drill holes. Lannister Mining reports the mineralization is open at depth, along strike and untested regionally, with about two-thirds of the property still unexplored.
Basin Gulch is in west-central Montana, within the historic Philipsburg Mining District in Granite County. It has year-round access from Philipsburg on paved and well-maintained gravel roads, and is about one hour from Butte.
Lannister Mining defines Basin Gulch as a property primarily on patented land, hosted in oxides, with over 320 historical drill holes. It is underlain by a core of patented mining claims surrounded by unpatented mining claims.
The company states that the property has potential to host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical drill intercepts. Until that estimate exists, every result here is historical.
As published by Lannister Mining, as of November 2026.
Lannister Mining reports that about two-thirds of Basin Gulch has not yet been explored. The known gold and silver mineralization is open in multiple directions and at depth, which means past drilling has not closed off its edges.
The company plans to use historical drilling and new work programs in a future maiden mineral resource estimate, and says future drilling will concentrate on additional mineralized target areas within the property. It lists multiple high priority targets near the historic resource area.
Because the gold and silver are near surface, the company describes significant implied flexibility in any future mine design optimization.

Basin Gulch is in west-central Montana, reached year-round from the town of Philipsburg on paved and well-maintained gravel roads. Lannister Mining describes the property as about one hour from Butte. It lies within the historic Philipsburg Mining District, also known as the Flint Creek Mining District, in Granite County.
The Basin Gulch land package totals 1,107 hectares. It is made up of 11 patented claims and 53 unpatented claims, 64 claims in all. Lannister Mining describes it as a large, consolidated land package with multiple high priority targets near the historic resource area.
About two-thirds of the Basin Gulch Property is still unexplored, according to Lannister Mining. The company also states that the known mineralization is open at depth, open along strike, and untested regionally. That combination is the main exploration upside the company points to when speaking with partners and investors.
In the United States, a patented mining claim is privately owned land, while an unpatented claim gives mineral rights on public land without owning the surface. Basin Gulch has 11 patented claims at its core, surrounded by 53 unpatented claims. Lannister Mining notes the property is primarily on patented land.
Oxide mineralization is metal-bearing rock that has been weathered near the surface, so the original sulfide minerals have been altered to oxides. In general, oxide material near surface is easier to reach than deeper ore. At Basin Gulch, Lannister Mining describes the gold and silver as hosted in oxides and near surface.
Open at depth means drilling has not yet found the bottom of the mineralization; open along strike means its sideways extent along the trend has not been closed off. Lannister Mining says Basin Gulch mineralization is open in multiple directions and at depth, which leaves room to grow the known footprint.
