History

A state built on mining

Montana is known as the Treasure State because of its vast wealth of mineral reserves and a history built on mining. The industry continues to play an active role in the state's economy today.

The first gold discovery in what was known as 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, and Montana is home to world-class deposits.

US jurisdiction

Why does a US address matter to investors?

Lannister Mining states that 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 NI 43-101 compliant resources are trading at a significant premium compared to their peers. That is the company's view of the market, not an independent study.

S-K 1300 is the disclosure standard the US Securities and Exchange Commission applies to mining properties. You can read the rule on the SEC website. The US Geological Survey publishes gold statistics and information for readers who want national production context.
