The Swan Peak mining district is located 25 mi northeast of Logan in the Wasatch Range straddling the CacheβRich County line. The district was organized in 1900, was most productive from 1900 into the 1920s, and was a minor Ag-Pb producer. Total district metal production at modern metal prices is estimated at $25,000. The district only has six recorded mines or prospects and the Amazon Ag-Pb-Zn mine is the only recognized producer (Perry and McCarthy, 1977).
The Wasatch Range is geologically situated in the Middle Rocky Mountain province. The major feature of the Swan Peak district is the northerly trending, upright, open Swan Peak syncline in the upper plate of the west-dipping Paris thrust (Dover, 2007). The primary strata in the syncline are Cambrian carbonate rocks and shale and Ordovician carbonate rocks and sandstone. The Middle Cambrian Blacksmith Fork Formation and the overlying Bloomington Formation are the primary ore hosts. The Amazon mine in Amazon Hollow lies on the west limb of the Swan Peak syncline near a mapped northwest-trending high- angle fault. Bedding at the mine strikes northwest and dips gently to the northeast. The underground workings intersect a series of west-northwest- and east-northeast-trending fractures and an easterly trending, south-dipping breccia zone (Heyl, 1963). Primary sulfide mineralization observed at the mine includes pockets of galena, sphalerite, pyrite, and trace chalcopyrite in a gangue of dolomite, ankerite, calcite, and barite (Heyl, 1963; Chappelle, 1975). Heyl (1963) reported high-grade ore samples having up to 850 ppm Ag.
