Historical drilling
Last updated: November 2026 · Published by Lannister Mining
More than 320 historical drill holes have been completed at Basin Gulch, and the highlight intercepts include 1.8 g/t gold over 162 meters from surface.
Lannister Mining publishes five historical drill intersections and four trench highlights for Basin Gulch in Montana. Several drill intervals start at surface and run for tens to hundreds of meters, and the trenches report both gold and silver. All are historical results that the company plans to confirm before a maiden resource estimate.
The longest high-grade historical intercept is 1.8 g/t gold over 162 meters from surface. The longest overall is 0.66 g/t gold over 326 meters from surface, and the highest grade listed is 156 g/t gold over 3 meters.
| Gold grade | Interval | Start |
|---|---|---|
| 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 | Silver | 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) |
Grades are in grams per tonne (g/t). A result of 1.8 g/t gold over 162 meters means the sampled rock averaged 1.8 grams of gold per tonne along that 162 meter length. Long intervals starting at surface matter because oxide material near surface is generally easier to reach.
These are highlights chosen by Lannister Mining from a much larger historical dataset of more than 320 holes. They are not averages of the whole property.
Plan steps as stated by Lannister Mining, as of November 2026.
Highlight historical drill intersections published by Lannister Mining include 1.8 g/t gold over 162 meters from surface, 0.66 g/t gold over 326 meters from surface, 3.2 g/t gold over 72 meters from surface, 156 g/t gold over 3 meters, and 25 g/t gold over 14 meters. These are historical results, not a current resource.
Lannister Mining publishes four historical trench highlights: 62 g/t gold and 32 g/t silver over 159 meters; 4 g/t gold and 23 g/t silver over 146 meters; 5 g/t gold and 54 g/t silver over 34 meters; and 25 g/t gold and 45 g/t silver over 61 meters. They are shown exactly as the company reports them.
g/t means grams per tonne, the number of grams of metal in one metric tonne of rock. A result such as 1.8 g/t gold over 162 meters means the drill core averaged 1.8 grams of gold per tonne along a 162 meter length. Longer intervals at a given grade generally indicate more continuous mineralization.
Historical drill results are useful for targeting but are not the same as a current, compliant resource. That is why Lannister Mining plans confirmation drilling of historical intercepts before a maiden resource estimate. Readers should treat every historical number on this site as historical and confirm current status with the company.
Not yet. Lannister Mining states that historical drilling and new work programs will be used in a future maiden mineral resource estimate. The company describes the property as having potential to host a significant maiden resource after expansion and confirmation drilling of historical drill intercepts. Until then, results should be treated as historical.
Lannister Mining states that future drilling will concentrate on additional mineralized target areas within the property, alongside confirmation and expansion drilling of historical intercepts. The company has not published a specific schedule on the pages this site draws from. For current program details, contact its investor relations team.
