How to read Basin Gulch drill intercepts

Definition

What a drill intercept tells you

A drill intercept pairs a grade with a length. At Basin Gulch, Lannister Mining reports gold grade in grams per tonne (g/t Au) and interval length in both meters and feet. A long interval at modest grade, such as 0.66 g/t over 326 meters, points to a broad mineralized body. A short interval at high grade, such as 156 g/t over 3 meters, points to a rich zone or structure inside it.

Three of the five highlights start at surface. For an oxide deposit, near-surface mineralization matters because it is the material reached first. Lannister Mining describes this setting as giving significant implied flexibility for future mine design optimization.

Status

Are these results a resource yet?

No. These are historical results. Lannister Mining plans expansion and confirmation drilling of historical intercepts, then a maiden mineral resource estimate that uses both historical and new data. Treat them as strong indicators of potential, and check the company technical disclosures for current status.

Assumptions: grade-thickness is grade multiplied by interval length, a common shorthand for comparing intercepts. It ignores true width, recovery, cut-off grade and silver credits. This is an estimate for comparison only, not a resource figure, valuation or investment decision.

Common questions

Short answers here. More than 40 questions are answered on the Basin Gulch FAQ.

How many holes have been drilled at Basin Gulch?: More than 320 historical drill holes have been completed at Basin Gulch, according to Lannister Mining. That body of historical work is the foundation the company plans to build on, together with new work programs, for a future maiden mineral resource estimate. Expansion and confirmation drilling of historical intercepts is part of that plan.
What is the longest drill intercept reported at Basin Gulch?: The longest highlight intercept Lannister Mining reports is 0.66 g/t gold over 326 meters, or 1,069.6 feet, starting from surface. A second long interval is 1.8 g/t gold over 162 meters, or 531.5 feet, also from surface. Both are historical results listed on the company property page.
What is the highest-grade drill result at Basin Gulch?: The highest-grade highlight Lannister Mining lists is 156 g/t gold over 3 meters, or 9.8 feet. Another high-grade interval is 25 g/t gold over 14 meters, or 45.9 feet. The company property page does not state the starting depth for these two intervals, so this site does not show one.
Do the Basin Gulch drill intercepts start at surface?: Three of the five highlight drill intercepts start at surface: 1.8 g/t gold over 162 meters, 0.66 g/t gold over 326 meters and 3.2 g/t gold over 72 meters. Mineralization that begins at surface matters to investors because near-surface oxide material is generally simpler to reach than deep ore.
What does g/t Au mean in drill results?: g/t Au means grams of gold per tonne of rock. One gram per tonne equals one part per million, and a troy ounce is about 31.1 grams. Drill results pair a grade with an interval length, so 1.8 g/t gold over 162 meters describes both how rich and how long the mineralized section was.
What is confirmation drilling?: Confirmation drilling means drilling new holes near historical holes to check that the earlier grades and widths can be reproduced with modern methods. It is a standard step before historical data can support a current resource estimate. Lannister Mining lists expansion and confirmation drilling of historical intercepts as part of its Basin Gulch plan.
Where can I download Basin Gulch drill data?: The most complete public source is the Lannister Mining June 2026 USA investor presentation, linked on the technical downloads page, alongside property maps from the company website. A full historical drill database is not posted publicly. Technical investors and partners can request more detail through the Lannister Mining contact page.
