Clark Fork Coverage: Full drainage from Warm Springs, MT to Lake Pend Oreille, ID (~500 mi).
Includes Blackfoot, Bitterroot, Flint Creek, Rock Creek, Lightning Creek, and all major tributaries.
Clark Fork Minerals (20+ types):
• Gold — Placer & lode throughout drainage
• Silver — Granite Mine (historic US top producer), CdA Belt
• Garnet — Almandine in metamorphic belts (Cabinet Mtns, Bitterroot Range)
• Sapphire — MT State Gem; Gem Mountain (Rock Creek area), Sapphire Mtns
• Copper — Butte District (Clark Fork headwaters), Cabinet Mtns
• Lead/Zinc/Ag — Coeur d'Alene Belt (Idaho Panhandle)
• PGE — Stillwater Complex (regional context; world's only US PGE mine)
• Molybdenum/Tungsten — Boulder Batholith contact skarns
• Talc — Montana top US producer (Bitterroot/Ravalli Co.)
• Phosphate — Western MT / Phosphoria Formation
• Uranium — Central MT occurrences; Idaho phosphate belt
