What does a gold exploration company like Lannister Mining do?

A gold exploration company finds, tests and measures gold deposits before any mine is built. Lannister Mining does this at one property, Basin Gulch, where historical drilling has outlined gold and silver mineralization that is open at depth, open along strike and untested regionally.

The next step is expansion and confirmation drilling of historical intercepts, combined with new work programs, to support a maiden mineral resource estimate. Future drilling will also concentrate on additional mineralized target areas within the property, about two-thirds of which is still unexplored.

Lannister Mining, defined

Why Basin Gulch stands out

Significant historical work

More than 320 historical drill holes have already tested Basin Gulch, giving the company a deep record to confirm and build on.

A large, consolidated land package

11 patented claims and 53 unpatented claims covering 1,107 hectares, with multiple high priority targets near the historic resource.

Near-surface gold and silver in oxides

Mineralization sits near surface and is hosted in oxides, which the company says gives significant mine design optimization flexibility.

An established mining district

Basin Gulch lies in the historic Philipsburg Mining District, which led the original US silver boom in the late 1800s.

How is Lannister Mining different from other mineral exploration companies?

Many mineral exploration companies are still searching for a first discovery. Lannister Mining starts from a property that has already seen more than 320 historical drill holes and has not been mined out, in a US jurisdiction with a long mining record.

The company states that US-based companies with NI 43-101 compliant resources trade at a significant premium compared to their peers, which is why a maiden resource at Basin Gulch is its central goal.
