Project profile
Published by Lannister MiningLast updated November 2026
Basin Gulch is a gold and silver oxide exploration property in the historic Philipsburg Mining District of west-central Montana, owned by Lannister Mining.
The property is primarily on patented land, hosted in oxides, and has seen more than 320 historical drill holes. Mineralization is open at depth, along strike and untested regionally. Lannister Mining plans expansion and confirmation drilling toward a maiden mineral resource estimate.
Basin Gulch combines near-surface gold-silver oxide mineralization, a large body of historical drilling, and a consolidated 1,107-hectare land package with two-thirds still unexplored. It has year-round road access from Philipsburg and sits about one hour from Butte.

Year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads. About one hour from Butte. Year-round access can let crews work outside the short summer windows some northern jurisdictions face.
High-grade gold-silver mineralization near surface, hosted in oxides. Lannister Mining describes significant implied mine design optimization flexibility, and notes mineralization is open in multiple directions and at depth.

Read this answer in the full FAQBasin Gulch has seen more than 320 historical drill holes. Lannister Mining plans to use that historical drilling, together with new work programs, in a future maiden mineral resource estimate after expansion and confirmation drilling of historical intercepts. The historical holes are a large head start for a property at the exploration stage.
Read this answer in the full FAQNot yet. Basin Gulch does not currently have a published compliant mineral resource estimate. Lannister Mining plans a maiden mineral resource estimate that would use historical drilling and new work programs, after expansion and confirmation drilling of historical intercepts. Investors should treat historical results as historical until that work is complete.
Read this answer in the full FAQA patented claim is a mining claim where the federal government has transferred full title to the land, so it is held like private property. An unpatented claim gives the right to explore and develop minerals on federal land, but the government keeps title. Basin Gulch combines both: 11 patented claims at its core and 53 unpatented claims around them.
Read this answer in the full FAQBasin Gulch has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and it is about one hour from Butte. Year-round road access matters for exploration because it lets crews drill and sample outside short summer seasons, which can lower costs compared with fly-in or seasonal projects.
Read this answer in the full FAQNo. Basin Gulch is a mineral exploration property, not a recreational panning site. It is made up of 11 patented and 53 unpatented mining claims held for Lannister Mining's exploration work.
