Gold exploration in Montana, explained through Basin Gulch
Published by Lannister Mining Last updated November 2026
Gold exploration in Montana means testing the state's historic mining districts for new gold and silver resources, and the Basin Gulch Property near Philipsburg is a drill-tested example.
Lannister Mining, the publisher of this guide, is exploring the Basin Gulch Property in west-central Montana for gold and silver. The land package holds 11 patented and 53 unpatented claims across 1,107 hectares, with more than 320 historical drill holes, near-surface oxide-hosted mineralization, and two thirds of the ground still unexplored.
What does gold exploration in Montana look like today?
Most gold exploration in Montana today returns to ground that earlier miners and drillers already touched, using modern standards to measure what is there. Basin Gulch is a clear case: more than 320 historical drill holes and trenches outline gold and silver mineralization that is open at depth, along strike, and untested regionally.
The work ahead is confirmation and expansion drilling of those historical intercepts, followed by a future Maiden Mineral Resource Estimate. Lannister Mining also plans to drill additional mineralized target areas across the two thirds of the property that has not yet been explored.
What is gold exploration?
Gold exploration is the staged search for gold deposits that could one day be mined: mapping and sampling, then trenching and drilling, then a formal mineral resource estimate prepared by a qualified person. Each step costs more than the one before, so results decide whether the next step goes ahead.
At the Basin Gulch Property, Lannister Mining starts well along that path. Historical drilling and trenching already exist, the mineralization is hosted in oxides near surface, and the property is primarily on patented land. The step still missing is a modern resource estimate, which is the company's stated goal.

Montana gold exploration: why the Treasure State still matters
Montana gold exploration began with the first gold discovery in the Montana territory in 1852 at Gold Creek, near present-day Garrison. Silver, copper, nickel, and platinum followed, and mining still plays an active role in the state's economy.
Basin Gulch sits in the heart of the historic Philipsburg Mining District, which led the original US silver boom in the late 1800s. Year-round access from Philipsburg on paved and well-maintained gravel roads keeps drilling programs practical through the seasons.

| Exploration stage | What it involves | Where Basin Gulch stands |
|---|---|---|
| Target generation | Choosing ground with geological promise | Historic Philipsburg Mining District |
| Land tenure | Securing mineral rights | 11 patented and 53 unpatented claims, 1,107 hectares |
| Surface sampling and trenching | Mapping and sampling exposed rock | Historical trenches with gold and silver results |
| Drilling | Measuring grade and thickness at depth | More than 320 historical drill holes |
| Resource estimate | Formal estimate by a qualified person | Planned: future Maiden Mineral Resource Estimate |
How Basin Gulch moves toward a maiden resource
Review the historical record
Compile the data from more than 320 historical drill holes and the trench program.
Confirm historical intercepts
Drill new holes to confirm results such as 1.8 g/t Au over 162 meters from surface.
Expand along strike and at depth
Test where mineralization remains open, and drill additional target areas on the property.
Estimate a maiden resource
Combine historical and new work into a future Maiden Mineral Resource Estimate.
The sequence follows Lannister Mining's published plan. See the stages of mineral exploration for the full process.

Common questions
Short answers from the full gold exploration FAQ.
What is gold exploration?
Gold exploration is the work of finding and measuring gold deposits before any mine is built. It moves from mapping and sampling to trenching and drilling, then to a resource estimate. In Montana, Lannister Mining is applying that process to the Basin Gulch Property, where more than 320 historical drill holes give a head start on the drilling stage.
Where is the Basin Gulch Property?
The Basin Gulch Property is in west-central Montana, in the historic Philipsburg Mining District. Lannister Mining states it has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and it is about one hour from Butte. That access matters for drilling programs, because crews and equipment can reach the site through the seasons.
How many claims are in the Basin Gulch Property?
The Basin Gulch land package includes 11 patented claims and 53 unpatented claims, covering 1,107 hectares, according to Lannister Mining. The property is built around a core of patented mining claims surrounded by unpatented mining claims. Lannister Mining also describes multiple high priority targets near the historic resource area.
What are the best historical drill results at Basin Gulch?
Highlight historical intercepts published by Lannister Mining include 1.8 g/t Au over 162 meters from surface, 0.66 g/t Au over 326 meters from surface, 3.2 g/t Au over 72 meters from surface, 156 g/t Au over 3 meters, and 25 g/t Au over 14 meters. These are selected highlights, not averages for the property.
Does Basin Gulch have a mineral resource estimate?
Not yet. Lannister Mining states that historical drilling and new work programs will be used in a future Maiden Mineral Resource Estimate, after expansion and confirmation drilling of historical drill intercepts. A maiden estimate is the first formal resource reported for a project under a recognized disclosure standard.
Why is Montana a good place for gold exploration?
Montana is known as the Treasure State because of its mineral wealth and long mining history, and mining still plays an active role in the state's economy. Gold, silver, copper, nickel, and platinum have all been discovered and mined there. Established districts offer roads, nearby towns, and decades of historical data.
