Exploration upside

Last updated: November 2026

Basin Gulch exploration potential

About two-thirds of the Basin Gulch Property is still unexplored, and the known mineralization is open at depth, along strike and untested regionally. Lannister Mining plans expansion and confirmation drilling of historical intercepts, with the goal of a future maiden mineral resource estimate.

What is the exploration potential at Basin Gulch?

The potential lies in three directions: deeper beneath long surface intercepts, laterally along strike, and across unexplored ground covering two-thirds of the property. Multiple high priority targets sit near the historic resource.

Potential in context

Definition

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 property, prepared under a recognized reporting standard. For Basin Gulch, the relevant standards are S-K 1300 in the United States and NI 43-101 in Canada.

Lannister Mining plans to use historical drilling and new work programs in a future maiden estimate for the Basin Gulch Property, after expansion and confirmation drilling. No date for the estimate has been published.

Planned work toward a maiden estimate

  1. Confirmation drilling

    Re-test historical drill intercepts so they can support a modern estimate.

  2. Expansion drilling

    Step out at depth and along strike, where mineralization is open.

  3. Target drilling

    Concentrate on additional mineralized target areas within the property.

  4. Maiden mineral resource estimate

    Combine historical drilling and new programs into a first formal estimate.

Why the property suits exploration partners

Basin Gulch combines a large historical dataset with untested ground. More than 320 historical drill holes and four trench highlights give a starting model, while two-thirds of the property offers room to discover new zones. The property has not been mined out, is primarily on patented land, and has year-round access from Philipsburg. The technical leadership includes professional geologists on the board, and the team includes many of the same co-founders or senior executives as K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold.

Common questions

Short answers to what field geologists and exploration partners ask most often.

How much of Basin Gulch is unexplored?

About two-thirds of the Basin Gulch Property is still unexplored. That leaves large parts of the 1,107 hectare land package without drilling or trenching, alongside multiple high priority targets near the historic resource area.

What is a maiden mineral resource estimate?

A maiden mineral resource estimate is the first formal estimate of the tonnage and grade of a deposit, prepared under a public reporting standard such as NI 43-101 in Canada or S-K 1300 in the United States. Lannister Mining plans one for Basin Gulch using historical drilling and new work.

When will Basin Gulch have a mineral resource estimate?

Lannister Mining describes the maiden mineral resource estimate as a future milestone, to follow expansion and confirmation drilling of historical drill intercepts. This site does not publish a date. Lannister Mining's main website carries the company's latest project updates.

What are the next exploration steps at Basin Gulch?

Planned work includes expansion and confirmation drilling of historical drill intercepts, followed by a maiden mineral resource estimate. Future drilling will also concentrate on additional mineralized target areas within the property, including multiple high priority targets near the historic resource.

Why is Basin Gulch of interest to exploration partners?

Basin Gulch combines more than 320 historical drill holes, oxide-hosted gold and silver from surface, mineralization open in multiple directions, and about two-thirds of the land still unexplored. It also has year-round road access and sits on a core of patented land.

Does Basin Gulch have regional exploration targets?

Yes. The property is described as untested regionally, and future drilling will concentrate on additional mineralized target areas within the property. Multiple high priority targets lie near the historic resource, inside a consolidated 1,107 hectare land package.
