What is Lannister Mining planning at Basin Gulch?

In short: confirm, expand, explore, then estimate. Each step below is drawn from how Lannister Mining describes the project. Timing, budgets and hole counts for current programs appear in the company's latest investor presentation.

  1. 1

    Use the historical record

    More than 320 historical drill holes and trench results form the starting dataset for Basin Gulch.

  2. 2

    Confirm historical intercepts

    Confirmation drilling re-tests selected historical intercepts so they can support a modern estimate.

  3. 3

    Expand known mineralization

    Expansion drilling tests where mineralization is open at depth and along strike.

  4. 4

    Test new targets

    Future drilling concentrates on additional mineralized target areas within the property.

  5. 5

    Prepare a maiden mineral resource estimate

    Historical drilling and new work programs are combined into a first formal resource estimate.

What is a maiden mineral resource estimate?

A maiden mineral resource estimate is the first formal estimate of the tonnes and grade of mineralization on a project, prepared by a qualified person to a recognized standard. For Lannister Mining at Basin Gulch, it would turn historical drilling and new results into reportable gold and silver ounces.

In Canada the governing rule is NI 43-101; in the US it is S-K 1300, explained by the US Securities and Exchange Commission.

Why the estimate is the central goal

Lannister Mining states there is a clear premium in the market for S-K 1300 and NI 43-101 compliant gold and silver ounces in the USA, and that US-based companies with 43-101 compliant resources trade at a significant premium compared to their peers.

That is the company's stated reason for prioritizing a maiden estimate. It is a view, not a guarantee: the size and grade of any resource depend on what drilling confirms.

Where exploration partners fit

A program like this calls for drilling contractors, geological consultants, laboratories and capital partners. Basin Gulch offers them a consolidated land package, a long historical dataset and year-round road access from Philipsburg, about an hour from Butte.

Lannister Mining welcomes exploration partners who want to understand the project. The stages of mineral exploration page explains where the project sits in the wider exploration cycle.

Questions people ask

What stage is the Basin Gulch Property at?
Basin Gulch sits between historical drilling and a first mineral resource estimate. More than 320 historical holes plus trenching have outlined gold and silver mineralization, and Lannister Mining plans confirmation and expansion drilling to support a maiden estimate. About two-thirds of the property remains unexplored, so earlier stage target work continues alongside the resource work.
What is a maiden mineral resource estimate?
A maiden mineral resource estimate is the first formal estimate of the tonnes and grade of mineralization on a project, prepared to a recognized reporting standard. For Lannister Mining, the plan is to combine historical drilling at Basin Gulch with new work programs. The company states that US companies with 43-101 compliant resources trade at a significant premium to peers.
What are NI 43-101 and S-K 1300?
NI 43-101 is the Canadian rule governing how companies disclose scientific and technical information about mineral projects. S-K 1300 is the equivalent US Securities and Exchange Commission rule. Both require a qualified person and define categories for resources and reserves. Lannister Mining states there is a clear market premium for compliant gold and silver ounces in the USA.
What will future drilling at Basin Gulch focus on?
Lannister Mining states that future drilling will concentrate on additional mineralized target areas within the property, alongside expansion and confirmation drilling of historical intercepts. The aim is to support a maiden mineral resource estimate and to test ground that remains open at depth, along strike and regionally. The latest investor presentation carries current program details.
How long does mineral exploration take?
Mineral exploration usually takes years, and the path from discovery to a producing mine commonly takes a decade or more, depending on drilling results, studies, permitting and financing. Projects with extensive historical drilling, such as Basin Gulch, start with more data, but that data still needs confirmation. The Lannister Mining investor presentation is the place to check current plans.
Is Lannister Mining interested in exploration partners?
Yes. This site is written for investors and industry partners, and Lannister Mining wants exploration partners to understand Basin Gulch clearly. The property offers a consolidated 64 claim package, more than 320 historical drill holes and roughly two-thirds of its ground still unexplored. Partnership discussions run through the company itself, and lannistermining.com is its official channel.
