Why Montana for gold and silver exploration

Montana is called the Treasure State for its mineral wealth. Its first gold discovery came in 1852 at Gold Creek, near present-day Garrison, and silver, copper, nickel and platinum have since been mined. The Philipsburg Mining District, home of Basin Gulch, led the original US silver boom in the late 1800s.

Lannister Mining also points to the market for US ounces: it states that US-based companies with 43-101 compliant resources trade at a significant premium compared to their peers. Montana-based exploration lets the company pursue that kind of resource on US soil.
