Exploration plans for Basin Gulch

Lannister Mining plans to confirm and expand historical drill results at Basin Gulch, then complete a Maiden Mineral Resource Estimate.

Last updated: November 2026

What exploration is planned at Basin Gulch?

Basin Gulch exploration, as planned by Lannister Mining, starts with confirmation and expansion drilling of historical intercepts, leading to a Maiden Mineral Resource Estimate. Future drilling will then concentrate on additional mineralized target areas across the two thirds of the property that is still unexplored.

The exploration plan in four cards

Definition: exploration upside at Basin Gulch

Exploration upside is the chance that more drilling finds more mineralization. At Basin Gulch, Lannister Mining points to three reasons: mineralization is open in multiple directions and at depth, it is open along strike and untested regionally, and two thirds of the property is still unexplored.

The company also notes multiple high priority targets near the historic resource area, and year round road access that lets work continue across the seasons.

The Basin Gulch exploration sequence

  1. Compile the historical record

    Bring together results from more than 320 historical drill holes and surface trenching across the patented core of the property.

  2. Confirmation drilling

    Re drill selected historical intercepts so their grades and widths can be relied on under a current reporting standard.

  3. Expansion drilling

    Step out from known mineralization, which Lannister Mining describes as open at depth, along strike and in multiple directions.

  4. Maiden Mineral Resource Estimate

    Combine historical drilling and new work programs into the first formal resource estimate for Basin Gulch.

  5. Test new target areas

    Concentrate future drilling on additional mineralized target areas within the two thirds of the property still unexplored.

Confirmation drilling or expansion drilling: what is the difference?

What is a Maiden Mineral Resource Estimate?

It is the first formal estimate of how much mineralized rock a project holds, and at what grade.

A maiden estimate is prepared by a qualified person under a recognized reporting standard. In the United States that is SEC Regulation S-K 1300, and in Canada it is NI 43-101. Lannister Mining states there is a clear market premium for US gold and silver ounces that are compliant with these technical report standards.

At Basin Gulch, the company says historical drilling and new work programs will be used in the future maiden estimate, and that the property has potential to host a significant estimate after expansion and confirmation drilling. No resource estimate has been published, and no timeline is stated on this site.

What is a maiden mineral resource estimate?

A maiden mineral resource estimate is the first formal estimate of the tonnage and grade of mineralization on a project, prepared under a recognized reporting standard. In the United States that standard is SEC Regulation S-K 1300, and in Canada it is NI 43-101. Lannister Mining plans a maiden estimate for Basin Gulch.

What are NI 43-101 and S-K 1300?

NI 43-101 is the Canadian standard for disclosing mineral project information, and S-K 1300 is the United States Securities and Exchange Commission's rule for mining property disclosure. Both rely on a qualified person. Lannister Mining states there is a clear market premium for US gold and silver ounces that are compliant with these technical report standards.

Is Basin Gulch mineralization open?

Yes. Lannister Mining states that gold and silver mineralization at Basin Gulch is open in multiple directions and at depth, open along strike, and untested regionally. Open means drilling has not yet found the edges of the mineralized zone, so further drilling could extend it in those directions.
