A former underground Au-Pb-Cu-Ag-Zn mine located 2 miles North of Mayer, about Β½ mile North of Big Bug Creek and 1 mile West of Poland siding. Started before 1866. Reopened 1915-1919. Also active 1926-1930. Owned by the Honorable C.E. Hitchcock & family; the Big Ledge Copper Co. (1915-1919); the Huron Copper Mining Co. (1923- ). The claim was rediscovered by a prospector about 1900. He named it in honor of Henrietta Crossman, the popular pin-up girl of the times.
Mineralization is a 2 to 6 foot wide vein of base metal ore hosted in the Lower Unit Spud Mountain Volcanics. The vein occurs mainly in massive, fine-grained amphibolite or diorite. It strikes North and dips about 70ΒΊWest. Gangue is massive quartz with some calcite. A vein spur strikes NNE (Invincible vein). It is a well defined quartz vein about 6 feet wide. On the lower levels, it is a solid quartz vein at 2 feet wide with massive sulfides. Ore control was faulting and shearing. Concentration was oxidation and enrichment at near surface. No alteration noted.
Workings include a 50 foot deep shaft (1868), an 80 foot deep shaft (1881); and later, a 500 foot deep shaft plus 1,500 tunnel through the ridge, 220 feet below the shaft collar & stoping. Later workings include a 2,200 foot long tunnel and a 600 foot deep winze.
