A gold exploration company searches for, tests and defines gold deposits before any mine is built. It acquires claims, maps and samples rock, drills, and works toward a resource estimate. Lannister Mining is a gold exploration company focused on the Basin Gulch Property in Montana.
An exploration company finds and defines deposits, while a mining company builds and operates mines that produce gold. Explorers usually fund work by selling shares, while producers earn revenue from metal sales. Some explorers later become producers or sell their projects to producers.
There is no single official ranking; lists of top gold exploration companies usually sort by market value, project size or drilling results, and they change often. This site does not rank companies. Lannister Mining's team has ties to K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold.
Yes. The United States has an active gold mining industry, and Montana has a gold history dating to the 1852 Gold Creek discovery. The US Geological Survey publishes national gold production data. Lannister Mining explores for gold and silver at Basin Gulch in Montana.
Typically a company acquires claims, reviews historical data, maps and samples at surface, trenches, drills, and then estimates a resource under a reporting standard. Basin Gulch already has historical drilling and trenching, and Lannister Mining's next milestone is a Maiden Mineral Resource Estimate.
Mining can disturb land, affect water quality and create waste rock, which is why it is closely regulated. In Montana, the Department of Environmental Quality oversees mine permitting and reclamation. Exploration usually has a smaller footprint than mining, though drilling and roads still need permits and reclamation.
Generally, drill pads and access trails are recontoured and reseeded, and drill holes are plugged under state rules. Requirements vary by land status and agency. For Montana specifics, see the Montana Department of Environmental Quality; for Basin Gulch plans, check Lannister Mining's disclosures.
Mostly through news releases on drilling, assays, royalties and financing. For example, Klondike Gold reported 513.1 ounces of placer flake gold at approximately 82% purity in 2026 royalty receipts from its Montana Creek Placer Property through October 15, 2026, per Mining Stock Education. Montana Creek is in the Yukon, not Montana.
It often takes many years, because discovery, resource definition, technical studies, permitting and financing each take time. Timelines vary widely by project and jurisdiction. Basin Gulch is at the stage of building toward a Maiden Mineral Resource Estimate.
