Historical drilling
Last updated: · Published by Lannister Mining
More than 320 historical drill holes have been completed at Basin Gulch, with highlights including 1.8 g/t gold over 162 meters from surface.
Lannister Mining reports these historical intercepts and trench results as the foundation for a future Maiden Mineral Resource Estimate. They are historical results, not a current mineral resource, and the company plans confirmation drilling before they are used in an estimate.
It depends on whether you value grade or width. The highest grade reported is 156 g/t Au over 3 meters. The widest from-surface intercept is 0.66 g/t Au over 326 meters, and 1.8 g/t Au over 162 meters from surface combines strong grade with long width.
| Gold grade | Length | Starting depth |
|---|---|---|
| 1.8 g/t Au | 162 m (531.5 ft) | From surface |
| 0.66 g/t Au | 326 m (1,069.6 ft) | From surface |
| 3.2 g/t Au | 72 m (236.2 ft) | From surface |
| 156 g/t Au | 3 m (9.8 ft) | Not stated |
| 25 g/t Au | 14 m (45.9 ft) | Not stated |

| Gold grade | Silver grade | Length |
|---|---|---|
| 62 g/t Au | 32 g/t Ag | 159 m (521.7 ft) |
| 4 g/t Au | 23 g/t Ag | 146 m (479 ft) |
| 5 g/t Au | 54 g/t Ag | 34 m (111.6 ft) |
| 25 g/t Au | 45 g/t Ag | 61 m (200.1 ft) |
Reading intercepts
A drill intercept pairs a grade, in grams per tonne, with a length. Long, from-surface intercepts such as 1.8 g/t Au over 162 meters suggest broad mineralization starting at the top of the hole, which Lannister Mining links to mine design flexibility. Short, very high-grade intervals such as 156 g/t Au over 3 meters show where gold is concentrated.
Surface sampling
Trenches expose rock at surface for continuous sampling. The Basin Gulch trench highlights report both gold and silver, including 62 g/t Au and 32 g/t Ag over 159 meters, confirming that the mineralization carries both metals at surface. Trench results do not by themselves define a resource.
Next step
Historical results must be checked with modern drilling before they can support a compliant resource estimate. Lannister Mining says Basin Gulch could host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling of historical drill intercepts.
Open zones
The mineralization remains open at depth and along strike, and two-thirds of the property is unexplored. See the exploration partner brief for how this shapes future targets, or return to gold exploration in Montana at Basin Gulch.
More than 320 historical drill holes have been completed at Basin Gulch. Lannister Mining plans to use this historical drilling, together with new work programs, in a future Maiden Mineral Resource Estimate after confirmation drilling of the historical intercepts.
