Gold and silver exploration in west-central Montana
Basin Gulch drilling is the record of more than 320 historical drill holes on the Basin Gulch Property, a gold and silver project in west-central Montana that Lannister Mining is exploring.
Lannister Mining's highlight results include 1.8 g/t gold over 162 meters from surface and 0.66 g/t gold over 326 meters from surface. The mineralization is hosted in oxides, sits primarily on patented land, and remains open at depth and along strike, with about two-thirds of the property still unexplored.

Basin Gulch drilling has found near-surface, oxide-hosted gold-silver mineralization with long intervals that start at surface. Three of the five highlight drill intercepts Lannister Mining publishes begin at surface, and the longest runs 326 meters. Trenches at surface returned gold and silver together, including 5 g/t Au and 54 g/t Ag over 34 meters.

Definition
The Basin Gulch Property is a gold and silver exploration project in west-central Montana, explored by Lannister Mining. It sits in the heart of the historic Philipsburg Mining District, which led the original United States silver boom in the late 1800s.
The property is underlain by a core of patented mining claims surrounded by unpatented claims: 11 patented and 53 unpatented, covering 1,107 hectares. Mineralization is hosted in oxides near surface and lies primarily on patented land. More than 320 historical drill holes have tested it, and it remains open at depth, along strike and untested regionally.
The property has not been mined out. Lannister Mining plans expansion and confirmation drilling of historical intercepts as the base for a future maiden mineral resource estimate.

Comparison
Basin Gulch has been tested two ways: drill holes that measure how mineralization continues downward, and trenches that expose it at surface. Both sets of results are compared here on the same criteria.
| Criterion | Drill holes | Trenches |
|---|---|---|
| What it tests | Mineralization at depth, from surface downward | Mineralization exposed at surface |
| How many are reported | More than 320 historical holes | Four highlight results published |
| Longest highlight | 0.66 g/t Au over 326 meters, from surface | 62 g/t Au and 32 g/t Ag over 159 meters |
| Highest gold grade highlight | 156 g/t Au over 3 meters | 62 g/t Au and 32 g/t Ag over 159 meters |
| Metals reported | Gold | Gold and silver |

Step by step
Lannister Mining describes a clear sequence for turning historical drilling into a formal estimate. Each step below comes from the company's published plans.
Start from more than 320 historical drill holes and the trench results already on record.
Drill to confirm historical intercepts so they can support a current estimate.
Drill beyond known mineralization, which is open at depth and along strike.
Concentrate future drilling on additional mineralized targets within the property.
Combine historical and new work in a Maiden Mineral Resource Estimate.
