Four short cards that each stand on their own: what the project is, its key numbers, its best historical intercepts, and the path to a first resource estimate.

Definition: the Basin Gulch Property

Basin Gulch is a gold and silver exploration property held by Lannister Mining in west-central Montana. It is primarily on patented land, with a core of 11 patented mining claims surrounded by 53 unpatented claims. Gold and silver mineralization is hosted in oxides, sits near surface, and remains open at depth, along strike and untested regionally.

The company plans expansion and confirmation drilling of historical intercepts, followed by a Maiden Mineral Resource Estimate. No resource estimate has been published yet.

How Basin Gulch moves toward a maiden resource estimate

  1. Compile the historical record

    Bring together results from more than 320 historical drill holes and surface trenching across the patented core of the property.

  2. Confirmation drilling

    Re drill selected historical intercepts so their grades and widths can be relied on under a current reporting standard.

  3. Expansion drilling

    Step out from known mineralization, which Lannister Mining describes as open at depth, along strike and in multiple directions.

  4. Maiden Mineral Resource Estimate

    Combine historical drilling and new work programs into the first formal resource estimate for Basin Gulch.

  5. Test new target areas

    Concentrate future drilling on additional mineralized target areas within the two thirds of the property still unexplored.

Basin Gulch historical drilling

More than 320 historical drill holes are the foundation of the Basin Gulch project.

Three of the five highlight intercepts start at surface, including 1.8 g/t Au over 162 meters and 0.66 g/t Au over 326 meters. Higher grade intervals include 156 g/t Au over 3 meters and 25 g/t Au over 14 meters. Trenching added gold and silver results such as 62 g/t Au and 32 g/t Ag over 159 meters.

Lannister Mining says this near surface mineralization implies significant flexibility for future mine design optimization. These are historical results, which the company plans to confirm with new drilling.

Basin Gulch exploration: what comes next

Planned Basin Gulch exploration has two jobs: confirm what the historical holes found, then test new ground.

Lannister Mining states that mineralization is open in multiple directions and at depth. Historical drilling and new work programs will feed a future Maiden Mineral Resource Estimate, and later drilling will concentrate on additional mineralized target areas. Two thirds of the property is still unexplored, which is where the company sees its exploration upside.

Why the Basin Gulch property in Montana draws investors and partners

The four reasons Lannister Mining gives for the project, in its own terms.

  • Significant historical work

    More than 320 historical drill holes give Basin Gulch a large body of past data to confirm and build on.

  • Large consolidated land package

    11 patented and 53 unpatented claims across 1,107 hectares, with multiple high priority targets near the historic resource area.

  • Safe jurisdiction

    In the heart of the historic Philipsburg Mining District, which led the original US silver boom in the late 1800s.

  • Potential for premium valuation

    Lannister Mining notes that US based companies with compliant resources trade at a significant premium compared with their peers.

Where is Basin Gulch?

West-central Montana, in the heart of the Philipsburg Mining District.

The property has year round access from Philipsburg on paved and well maintained gravel roads and is about one hour from Butte. Montana is known as the Treasure State, and the first gold discovery in what was then Montana territory came in 1852 at Gold Creek, near present day Garrison.

Note for searchers: the Basin Gulch Property is a mining claim package reached from Philipsburg. It is not a real estate listing in the town of Basin, Jefferson County.
