Basin Gulch Gold and Silver

Basin Gulch gold silver mineralization is near surface and hosted in oxides, and trench samples reported both metals over long intervals.

Lannister Mining describes high-grade gold-silver mineralization at Basin Gulch that is open in multiple directions and at depth. Trench highlights include 4 g/t gold and 23 g/t silver over 146 meters, and the company is working toward a maiden mineral resource estimate that would be the first formal statement of contained gold and silver.

What kind of gold and silver mineralization is at Basin Gulch?

Basin Gulch hosts near-surface, oxide-hosted gold-silver mineralization. Oxide rock has been weathered near the surface; across the industry, oxide material is generally simpler to process than unoxidized sulfide material, though processing choices are confirmed only by metallurgical testing.

Open in multiple directions

Lannister Mining reports the Basin Gulch mineralization 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 in those directions, so there is room to test for extensions.

Gold and silver together

Historical drill highlights are reported for gold. Trench highlights report gold and silver side by side, with silver ranging from 23 g/t over 146 meters to 54 g/t over 34 meters. No silver or gold resource has been estimated yet.

Basin Gulch gold and silver trench grades

These four trench highlights are listed exactly as Lannister Mining reports them. Trenches sample bedrock at surface, so they complement the drill record rather than replace it.

Why look for gold and silver in this part of Montana?

Montana is known as the Treasure State because of its vast mineral wealth and a history built on mining, and the industry still plays an active role in the state economy today.

A long mining history

The first gold discovery in what was then the Montana territory occurred in 1852 at Gold Creek, near present-day Garrison. Since then, silver, copper, nickel and platinum have all been discovered and mined in the state.

Basin Gulch sits in the heart of the historic Philipsburg Mining District, which Lannister Mining says led the original US silver boom in the late 1800s. Learn more about the district and access on the Basin Gulch property page.

How will gold and silver be measured formally?

Through a maiden mineral resource estimate. Lannister Mining plans to use historical drilling and new work programs to produce that first estimate. Read the maiden resource plan, review the historical drilling, or go back to the Basin Gulch project overview.

Questions about Basin Gulch gold and silver

What metals are found at Basin Gulch?
Gold and silver are the focus at Basin Gulch. Historical drilling reported gold intercepts, and trench sampling reported both gold and silver grades, such as 4 g/t gold and 23 g/t silver over 146 meters. Lannister Mining describes the target as near-surface, oxide-hosted gold-silver mineralization.
What does oxide-hosted gold mean?
Oxide-hosted gold sits in rock that has been weathered and oxidized near the surface. Lannister Mining describes Basin Gulch mineralization as hosted in oxides and near surface. Across the industry, oxide material is generally simpler to process than unoxidized sulfide material, though processing choices are confirmed only through metallurgical testing.
Is the Basin Gulch mineralization still open?
Yes. Lannister Mining reports that the gold-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 in those directions.
How much silver is at Basin Gulch?
No silver resource has been estimated yet. Reported silver values come from trench sampling, ranging from 23 g/t silver over 146 meters to 54 g/t silver over 34 meters in the highlights. A maiden mineral resource estimate would be the first formal statement of contained gold and silver.
Does Basin Gulch have high-grade gold?
Lannister Mining describes high-grade gold-silver mineralization near surface at Basin Gulch. Reported highlights include 156 g/t gold over 3 meters and 25 g/t gold over 14 meters from historical drilling, alongside long lower-grade intervals such as 0.66 g/t gold over 326 meters from surface.
Why does near-surface mineralization matter?
Near-surface mineralization can give flexibility in how a future mine could be designed. Lannister Mining points to significant implied mine design optimization flexibility at Basin Gulch because several highlight intercepts start at surface. Any mine design would first require a resource estimate and engineering studies.
Why explore for gold in Montana?
Montana is known as the Treasure State because of its mineral wealth and a history built on mining. The first gold discovery in the Montana territory occurred in 1852 at Gold Creek, near present-day Garrison, and silver, copper, nickel and platinum have since been discovered and mined in the state.
