Definition

What is the Basin Gulch Property?

The Basin Gulch Property is a gold and silver exploration project in west-central Montana, explored by Lannister Mining. It sits in the historic Philipsburg Mining District, which led the original United States silver boom in the late 1800s.

The property is primarily on patented land and its mineralization is hosted in oxides, close to surface. It covers 1,107 hectares across 11 patented and 53 unpatented claims, with a core of patented claims surrounded by unpatented ground. More than 320 historical holes have been drilled, yet about two-thirds of the property is still unexplored. Lannister Mining plans to combine the historical drilling with new work toward a maiden mineral resource estimate.

Step 4EstimateUse historical and new data in a maiden mineral resource estimate.
Step 5ExploreConcentrate future drilling on additional target areas.

Basin Gulch Lannister: who is behind the drilling

Basin Gulch is explored by Lannister Mining, a Montana-focused gold and silver company with its office in Vancouver, British Columbia.

Lannister Mining says its team includes many of the same co-founders or senior executives as K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold. CEO Jim Greig brings more than 25 years of experience advancing projects toward production, and advisor John Lewins, a mineral engineer with more than 35 years in the industry, is CEO of K92 Mining.

The company goal at Basin Gulch is clear: confirm and expand the historical drilling, then publish a maiden mineral resource estimate. It believes US gold and silver ounces that meet S-K 1300 and NI 43-101 standards attract a premium in the market.

Gold exploration in 2026: the market backdrop

Drilling decisions follow metal prices. Two recent market facts help frame where Basin Gulch sits.

A recent report on Great Basin drilling noted that gold futures ended the prior week at about $4,220 an ounce, and that Nevada producers and explorers were putting those prices to work with the drill (source: minenportal.de). The same report described a planned six-hole, approximately 930-metre program at a past-producing tungsten property in Elko County, Nevada.

For comparison, Basin Gulch already carries more than 320 historical drill holes. That existing record is what separates it from projects still waiting on their first holes. Prices move daily, so check a live quote before relying on any figure.

Common questions

Short answers here. More than 40 questions are answered on the Basin Gulch FAQ.

What is the Basin Gulch Property?: The Basin Gulch Property is a gold and silver exploration project in west-central Montana explored by Lannister Mining. It covers 1,107 hectares made up of 11 patented and 53 unpatented mining claims, hosts near-surface oxide mineralization, and has more than 320 historical drill holes that the company plans to use toward a future maiden mineral resource estimate.
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 the foundation the company plans to build on, together with new work programs, for a future maiden mineral resource estimate. Expansion and confirmation drilling of historical intercepts is part of that plan.
What is the longest drill intercept reported at Basin Gulch?: The longest highlight intercept Lannister Mining reports is 0.66 g/t gold over 326 meters, or 1,069.6 feet, starting from surface. A second long interval is 1.8 g/t gold over 162 meters, or 531.5 feet, also from surface. Both are historical results listed on the company property page.
How much of the Basin Gulch Property is unexplored?: About two-thirds of the Basin Gulch Property is still unexplored, according to Lannister Mining. The company calls this exploration upside, because the more than 320 historical drill holes are concentrated in part of the land package. The unexplored ground sits within the same 1,107-hectare package of patented and unpatented claims.
Are the historical Basin Gulch drill results part of a compliant resource?: Not yet. Lannister Mining says historical drilling and new work programs will be used in a future maiden mineral resource estimate, after expansion and confirmation drilling of historical intercepts. Until that work is done, treat historical intercepts as indicators of potential and check the company technical disclosures for the current status.

Is Basin Gulch Lannister the same place as Basin Gulch in the Shasta-Trinity National Forest?: No. Searches for Basin Gulch sometimes surface U.S. Forest Service pages about the Shasta-Trinity National Forest, which is in northern California. The Lannister Mining project is the Basin Gulch Property in the Philipsburg Mining District of west-central Montana, about one hour from Butte. Everything on this site refers to the Montana property.
