Gold and silver exploration in west-central Montana

Basin Gulch drilling: more than 320 holes into near-surface gold and silver

Last updated: November 2026. Published by Lannister Mining.

Basin Gulch drilling totals more than 320 historical holes on the 1,107-hectare Basin Gulch Property near Philipsburg, Montana.

Lannister Mining is advancing Basin Gulch, a near-surface gold and silver oxide project where historical drilling returned 1.8 g/t gold over 162 metres from surface. The mineralization is open at depth and along strike, two-thirds of the land package is unexplored, and the company plans confirmation drilling toward a Maiden Mineral Resource Estimate.

What is the Basin Gulch Property?

The Basin Gulch Property is a gold and silver exploration project in west-central Montana, advanced by Lannister Mining. It sits in the historic Philipsburg Mining District, which the company notes led the original United States silver boom in the late 1800s. The property is primarily on patented land, the mineralization is hosted in oxides, and it begins near surface.

Basin Gulch has seen significant historical work, including more than 320 drill holes, but it has not been mined out. The mineralization is open at depth, open along strike and untested regionally. Lannister Mining believes the property has potential to host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling of historical intercepts.

What is the Basin Gulch Property?: The Basin Gulch Property is a gold and silver exploration project in west-central Montana advanced by Lannister Mining. It hosts near-surface gold and silver oxide mineralization, has seen more than 320 historical drill holes and covers a 1,107-hectare land package made up of 11 patented and 53 unpatented mining claims.
How many holes have been drilled at Basin Gulch?: More than 320 historical drill holes have been completed at Basin Gulch, according to Lannister Mining. That body of historical work is one of the main reasons the property stands out among early stage gold projects, because it gives explorers a large existing dataset before any new drilling begins.
What are the best historical drill results at Basin Gulch?: Highlight historical intersections reported by Lannister Mining include 1.8 g/t gold over 162 metres from surface, 0.66 g/t gold over 326 metres from surface, 3.2 g/t gold over 72 metres from surface, 156 g/t gold over 3 metres and 25 g/t gold over 14 metres.
Does Basin Gulch have a mineral resource estimate?: Not yet. Lannister Mining plans to use historical drilling together with new work programs in a future Maiden Mineral Resource Estimate. Until that estimate is published, historical results on this site should be read as exploration data, not as a current mineral resource.
Where can I find a Basin Gulch map?: The Basin Gulch map page on this site shows the property location in Montana, the claim layout and the historical drilling area, using maps published by Lannister Mining. Each map links to its full-size version on the company website so you can zoom into the detail.
How much of Basin Gulch is still unexplored?: About two-thirds of the Basin Gulch Property is still unexplored, according to Lannister Mining. The company describes the mineralization as open at depth and along strike, and regionally untested, which is why the exploration targets page focuses on ground beyond the historical drilling area.
