Golden Chest

Name: Golden Chest, isotope signatures
Creator: IsoFind

Orogenic goldAu-W

Type: Mesothermal gold-tungsten veins

Gold-scheelite veins hosted in Proterozoic siliciclastic rocks (Belt Supergroup); uncertain Tertiary age. The old lead points to recycling of older common lead. Indicative coordinates.
