Basin Gulch Property, Philipsburg Mining District, Montana
Gold exploration companies in Montana: Lannister Mining at Basin Gulch
Last updated:
Lannister Mining is one of the US gold exploration companies, advancing the Basin Gulch Property, a high-grade, near-surface gold and silver oxide project in Montana’s historic Philipsburg Mining District.
For exploration partners comparing gold exploration companies in the United States, Lannister Mining’s Basin Gulch combines a consolidated land package of 11 patented and 53 unpatented claims (1,107 hectares), more than 320 historical drill holes, year-round road access from Philipsburg and a planned maiden mineral resource estimate. Two-thirds of the property is still unexplored.
Which gold exploration companies are active in Montana?
Lannister Mining is a gold exploration company active in Montana, working at the Basin Gulch Property near Philipsburg, about one hour from Butte. The company’s focus is high-grade gold and silver (Au-Ag) mineralization hosted in oxides and found near surface. Several historical drill intercepts begin at surface, including 1.8 g/t gold over 162 metres.
Montana is known as the Treasure State, and the Philipsburg Mining District led the original United States silver boom in the late 1800s. Basin Gulch sits in that district, primarily on patented land, with mineralization open at depth, along strike and untested regionally.

What is the Basin Gulch Property?
The Basin Gulch Property is Lannister Mining’s gold and silver exploration project in the Philipsburg Mining District of western Montana. It is a consolidated land package of 11 patented and 53 unpatented claims covering 1,107 hectares, with the patented claims forming the core and the unpatented claims surrounding them. The property is hosted in oxides and has seen more than 320 historical drill holes, yet it has not been mined out. The Au-Ag mineralization is open in multiple directions and at depth, and two-thirds of the ground is still unexplored. Historical drilling and new work programs will feed a future maiden mineral resource estimate. See the full Basin Gulch property facts.
Basin Gulch by the numbers
- 11 patented and 53 unpatented claims make up the Basin Gulch land package.
- 1,107 hectares of consolidated ground, roughly 2,735 acres.
- More than 320 historical drill holes completed on the property.
- 1.8 g/t Au over 162 metres from surface, one of several highlight historical intercepts.
- Two-thirds of the property still unexplored.
- About one hour by road from Butte, with year-round access from Philipsburg.
Two-thirds of the property still unexplored.
| Criterion | What technical readers look for | Basin Gulch |
|---|---|---|
| Land tenure | Secure, consolidated title | 11 patented claims at the core, 53 unpatented claims around them, 1,107 hectares |
| Drilling history | An existing dataset to build on | More than 320 historical drill holes plus historical trenching |
| Depth | Mineralization close to surface | Near-surface; intercepts such as 0.66 g/t Au over 326 m start at surface |
| Host rock | Processing-friendly mineralization | Gold and silver hosted in oxides |
| Room to grow | Open extensions and untested ground | Open at depth and along strike; two-thirds of the property unexplored |
| Access | Year-round road access | Paved and gravel roads from Philipsburg, MT; about one hour from Butte |
| Project status | A defined next milestone | Expansion and confirmation drilling, then a maiden mineral resource estimate |
What do the best US gold companies at the exploration stage have in common?
The best US gold companies at the exploration stage can be compared on the same evidence: secure land tenure, a meaningful drilling record, grade over width, depth from surface, host rock, access and a clear path to a mineral resource estimate. Comparing every project on these points, rather than on headlines, gives exploration partners a fair basis for judgment.
The table above applies those criteria to Basin Gulch. This website does not rank other companies; it sets out the Basin Gulch facts so technical readers can measure them against any project they are reviewing. Our guide to how to judge US gold exploration companies explains each criterion and the difference between exploration, development and production companies.
How does Basin Gulch move toward a maiden resource estimate?
- Start from historical work. More than 320 historical drill holes and trench results define the known mineralization.
- Expansion and confirmation drilling. New holes test and extend historical drill intercepts.
- Maiden mineral resource estimate. Historical drilling and new work programs are used in a first formal estimate.
- Drill new targets. Future drilling concentrates on additional mineralized target areas within the property.

Common questions
- What does Lannister Mining do?
- Lannister Mining is a gold and silver exploration company focused on high-grade, near-surface oxide mineralization at the Basin Gulch Property in Montana’s historic Philipsburg Mining District. The company holds 11 patented and 53 unpatented claims there and is working toward a future maiden mineral resource estimate built on historical drilling and new work programs.
- How many claims are on the Basin Gulch Property?
- The Basin Gulch Property includes 11 patented and 53 unpatented claims, a consolidated land package of 1,107 hectares. The patented mining claims form the core of the property and are surrounded by the unpatented claims, so most of the known mineralization sits on patented land.
- How many holes have been drilled at Basin Gulch?
- More than 320 historical drill holes have been completed at the Basin Gulch Property. That dataset, alongside historical trenching, is the starting point for the planned maiden mineral resource estimate, once expansion and confirmation drilling of the historical drill intercepts is complete.
- What type of mineralization is found at Basin Gulch?
- Basin Gulch hosts high-grade, near-surface gold and silver (Au-Ag) mineralization in oxides. Several historical intercepts start at surface, including 1.8 g/t gold over 162 metres. The mineralization is open at depth, along strike and regionally, and its near-surface position gives significant implied flexibility in future mine design optimization.
- Are there gold exploration companies in Montana?
- Yes. Lannister Mining is one of the gold exploration companies in Montana, advancing the Basin Gulch Property in the Philipsburg Mining District. Other companies also report Montana exploration; Junior Mining Network’s Montana news page lists 2026 results such as a hole that intersected 30.8 metres averaging 7.40 g/t gold.
- Has Lannister published a mineral resource estimate for Basin Gulch?
- Not yet. A maiden mineral resource estimate for Basin Gulch is planned for the future. The property has potential to host a significant maiden estimate after expansion and confirmation drilling of historical drill intercepts. Until then, historical drilling and trenching results describe the mineralization.
- Does this website cover gold mining stocks?
- No. This website presents Basin Gulch property facts, team background, exploration history and project status for exploration partners and technical readers. It does not discuss share prices, stock lists or buying shares. For general company information, visit the Lannister Mining website at lannistermining.com.
