The Basin Gulch Property: gold and silver exploration in west-central Montana

The Basin Gulch property is a gold and silver exploration project in west-central Montana with 11 patented and 53 unpatented mining claims covering 1,107 hectares.

Lannister Mining is exploring the Basin Gulch Property, which has seen more than 320 historical drill holes in oxide-hosted gold and silver mineralization. The mineralization is open at depth and along strike, two-thirds of the property is still unexplored, and the company plans confirmation and expansion drilling toward a Maiden Mineral Resource Estimate.

What is the Basin Gulch property?

The Basin Gulch property is a consolidated gold and silver exploration land package in the historic Philipsburg Mining District of west-central Montana, explored by Lannister Mining. Its core is 11 patented mining claims, which are private land, surrounded by 53 unpatented mining claims, for a total of 1,107 hectares.

It is not a home, a ranch listing or the Basin Gulch valley in California. It is a mineral property with a long drilling record and a plan for modern resource work, aimed at investors and exploration partners.

Definition: the Basin Gulch Property

The Basin Gulch Property is Lannister Mining's gold and silver project in west-central Montana. The known mineralization is hosted in oxides and sits primarily on patented land. Historical drilling of more than 320 holes returned intercepts that start at surface and run for long intervals, such as 1.8 g/t gold over 162 meters. Lannister Mining states the mineralization is open at depth, open along strike and untested regionally, and that two-thirds of the property has not been explored. The company describes the property as having potential to host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling.

Why the basin gulch property draws attention

Three facts work together. First, the existing record: more than 320 historical drill holes plus trenching, so explorers are not starting from a blank map. Second, tenure: the mineralized core is on patented land, surrounded by unpatented claims that cover open ground. Third, setting: the property sits in the Philipsburg Mining District, which led the original US silver boom in the late 1800s, with year-round road access from Philipsburg and about one hour from Butte.

What has not happened yet

Basin Gulch does not yet have a current mineral resource estimate, and this site does not state one. The drill and trench numbers on this site are historical results as reported by Lannister Mining. The company plans confirmation drilling of historical intercepts, expansion drilling and new work programs, which together would be used in a future Maiden Mineral Resource Estimate. Economic studies and permitting would come after that, if results support them.

Questions investors and partners ask first

Who is exploring Basin Gulch?
Lannister Mining, a mineral exploration company whose team includes co-founders or senior executives from K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold.
Where exactly is it?
In the historic Philipsburg Mining District of west-central Montana, with year-round access from Philipsburg on paved and well-maintained gravel roads, about one hour from Butte.
Is there a current resource estimate?
Not yet. Lannister Mining plans a Maiden Mineral Resource Estimate built from historical drilling and new work programs, after confirmation and expansion drilling.
Who is this site for?
Investors weighing gold exploration companies and exploration partners looking for a project with an existing drill record and open, largely untested ground.

How will the Basin Gulch property advance?

Lannister Mining plans to advance Basin Gulch in four steps, each building on the historical record rather than replacing it. The full plan is on the Basin Gulch exploration and resource development page.

  1. Put the historical record to work

    Use the results from more than 320 historical drill holes and trenching as the starting data set for new programs.

  2. Confirm historical intercepts

    Drill confirmation holes to check historical results such as 1.8 g/t Au over 162 meters from surface.

  3. Expand where it is open

    Drill at depth and along strike, where Lannister Mining states the mineralization remains open.

  4. Deliver a Maiden Mineral Resource Estimate

    Combine historical drilling and new work into a first resource estimate, then drill additional target areas.

Built for investors and exploration partners

For investors

Lannister Mining states there is a clear premium in the market for NI 43-101 and S-K 1300 compliant gold and silver ounces in the USA, and that Basin Gulch has seen significant historical work without being mined out. The Basin Gulch investor guide sets out the highlights, the criteria for judging gold exploration companies and the risks.

For exploration partners

Partners get an existing drill record, open mineralization, multiple high priority targets near the historic resource area and year-round access. The Basin Gulch exploration partner page compares the property with a greenfield project on the same criteria.

It includes 11 patented and 53 unpatented mining claims across 1,107 hectares and has seen more than 320 historical drill holes. The mineralization is oxide-hosted, open at depth and along strike, and the company plans further exploration and resource development.

Where is the Basin Gulch property located?

The Basin Gulch Property is in west-central Montana, in the historic Philipsburg Mining District. It has year-round access from Philipsburg on paved and well-maintained gravel roads and sits about one hour from Butte. The district led the original US silver boom in the late 1800s, so the property lies within a long-established mining region.

How many claims make up the Basin Gulch property?

The Basin Gulch Property has 64 claims in total: 11 patented mining claims and 53 unpatented mining claims. Together they form a consolidated land package of 1,107 hectares. Lannister Mining describes the layout as a core of patented claims surrounded by unpatented claims, with multiple high priority targets near the historic resource area.

What are the best historical drill results at Basin Gulch?

Lannister Mining lists these historical drill highlights: 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 historical results, which the company plans to confirm with new drilling.

Does Basin Gulch have a current mineral resource estimate?

This site does not state a current mineral resource estimate for Basin Gulch. Lannister Mining plans a future Maiden Mineral Resource Estimate built from historical drilling and new work programs, after expansion and confirmation drilling of historical intercepts. Until that estimate is published, the drill and trench numbers should be read as historical exploration results.

What stage of exploration is Basin Gulch at?

Basin Gulch is at the drilling-to-resource stage. Surface work, trenching and more than 320 drill holes were completed historically, and Lannister Mining now plans confirmation and expansion drilling that would feed a Maiden Mineral Resource Estimate. Economic studies, permitting and any development would come later and would depend on results.

Is this the same Basin Gulch as in California or Basin, Montana?

No. This site covers the Basin Gulch Property, a gold and silver exploration project near Philipsburg in west-central Montana. It is not the Basin Gulch valley in Trinity, California, and it is not a residential or ranch land listing near the town of Basin, Montana. Searches for basin gulch property can return all of these, so check the location.

Why would an exploration partner look at Basin Gulch?

Exploration partners look at Basin Gulch because it combines an existing data set of more than 320 historical drill holes with ground that is still largely untested. Mineralization is open at depth and along strike, two-thirds of the property is unexplored, and there are multiple high priority targets near the historic resource area, all with year-round road access.
