This district is centered around the town of Republic, which is also the County seat and only incorperated town in Ferry County. The district is located in the Republic graben, a major intracratonic, volcano-tectonic depression. The graben contains a thick sequence of Eocene volcanic and volcanoclastic rocks. A major hydrothermal system in the Republic District produced a series of Epithermal veins capped by hot-spring (sinter) deposits. The hot-spring deposits formed at paleosurfaces in the Sanpoil Volcanics prior to deposition of the overlying Klondike Mountain Formation. The majority of the recovered gold was from the epithermal veins. The veins exibit features indicative of episodic vein sealing and overpressuring followed by flashing and precipitation of precious metals, thus forming the charicteristic coloform bands. Geometrically, ore deposits in the Republic District extend from the paleosuface mineralization in hydrothermally altered rocks and sinter downward into epithermal stockworks and hydrothermal breccias, and farther downward into tightly confined, commonly colorform-banded veins.
