- More than 320 historical drill holes have been completed at the Basin Gulch Property, according to Lannister Mining. The company plans to use this historical drilling, together with new work programs, in a future maiden mineral resource estimate, after expansion and confirmation drilling of historical intercepts.
- Highlight historical intersections listed 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 mineral resource.
- Trench highlights listed on the Lannister Mining property page include 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 stated here exactly as the company publishes them.
- g/t means grams per tonne: the grams of metal contained in one metric tonne of rock. A result such as 1.8 g/t gold over 162 meters describes the average grade across that length of drill core or trench. Both grade and length matter, because a long interval of moderate grade can matter as much as a short, very high grade one.
- No. Historical drill results come from past programs and show where mineralization was found. A mineral resource estimate is a formal model of tonnes and grade prepared by a qualified person under standards such as NI 43-101 or S-K 1300. Lannister Mining plans confirmation drilling of historical intercepts before preparing its maiden mineral resource estimate.
- Mineral exploration drilling recovers rock from below the surface so geologists can measure what is there. Diamond core drilling produces solid cylinders of rock, while reverse circulation drilling returns rock chips more quickly and usually at lower cost. Results are reported as grades over lengths, and holes are spaced closer together as a project moves toward a resource estimate.
