Property fact sheetPublished by Lannister MiningLast updated: November 2026
Basin Gulch is a gold and silver exploration property near Philipsburg in west-central Montana, explored by Lannister Mining, with more than 320 historical drill holes into near-surface, oxide-hosted mineralization.
The property sits primarily on patented land, is open at depth and along strike, and is untested regionally. Lannister Mining says it has potential to host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical drill intercepts.
Basin Gulch lies in the heart of the historic Philipsburg Mining District, about one hour from Butte, with year-round access from Philipsburg on paved and well-maintained gravel roads. Historical drilling and trenching found gold and silver mineralization starting at surface, including 1.8 g/t gold over 162 meters from surface.
The property is built around a core of patented mining claims surrounded by unpatented mining claims. Lannister Mining reports multiple high-priority targets near the historic resource area, and says about two-thirds of the property has still not been explored.
Lannister Mining lists these highlight drill hole intersections from historical work at Basin Gulch. They are historical results and are not a mineral resource. The company plans confirmation drilling so they can support a future estimate.
| Gold grade | Interval length | Starting depth |
|---|---|---|
| 1.8 g/t gold | 162 meters (531.5 feet) | From surface |
| 0.66 g/t gold | 326 meters (1,069.6 feet) | From surface |
| 3.2 g/t gold | 72 meters (236.2 feet) | From surface |
| 156 g/t gold | 3 meters (9.8 feet) | Not stated |
| 25 g/t gold | 14 meters (45.9 feet) | Not stated |
g/t means grams of gold per metric tonne of rock. Long intervals that start at surface describe broad, shallow mineralization; short, high-grade intervals describe richer zones within it. Trenching also returned gold and silver over lengths of up to 159 meters, per Lannister Mining.
Lannister Mining says historical drilling and new work programs will be used in a future maiden mineral resource estimate, and that future drilling will concentrate on additional mineralized target areas. In practice, that path usually runs in five steps.
Drill new holes alongside historical ones so a qualified person can rely on the older data.
Step out at depth and along strike, where Lannister Mining reports the mineralization remains open.
Drill additional mineralized target areas across the roughly two-thirds of the property that is unexplored.
Bring the 320+ historical holes and new work programs into one geological model.
Release the first formal resource statement for Basin Gulch under a recognized reporting code.

More than 320 historical drill holes have been completed at Basin Gulch, according to Lannister Mining. Those holes tested near-surface gold and silver mineralization. The company says historical drilling and new work programs will feed a future maiden mineral resource estimate, after expansion and confirmation drilling of historical intercepts.
See this answer in the full FAQThe Basin Gulch land package covers 1,107 hectares, which is about 2,735 acres. It includes 11 patented claims and 53 unpatented claims, arranged as a core of patented mining claims surrounded by unpatented claims. Lannister Mining reports multiple high-priority targets near the historic resource area.
See this answer in the full FAQBasin Gulch hosts gold and silver mineralization that is near surface and hosted in oxides, according to Lannister Mining. The company describes it as open in multiple directions and at depth, open along strike, and untested regionally. It also says the shallow setting implies significant flexibility for optimizing a future mine design.
See this answer in the full FAQAbout two-thirds of the Basin Gulch property is still unexplored, according to Lannister Mining. The company says future drilling will concentrate on additional mineralized target areas within the property, alongside work on the historically drilled zone. That unexplored ground is a large part of the exploration upside the company describes.
See this answer in the full FAQNo. Lannister Mining describes Basin Gulch as an asset that has seen significant historical work but has not been mined out. That historical work includes more than 320 drill holes and trenching. The company is now working toward a maiden mineral resource estimate, which would be the first formal resource statement for the property.
