Cash Mine <br />The Cash mine workings were developed to explore and mine the Cash and Freiburg <br />veins. The Cash vein has an average strike of N56°E and dips from 54° to 80° to the <br />northwest and can be traced on the surface for approximately three-quarters of a mile, <br />with surface exposures ranging from 1 to 3 feet in width. The patented St. Joe claim <br />covers the northeastern extension of the Cash vein. The Freiburg vein joins the Cash vein <br />50 feet east of the shaft and strikes N35°E with a neazly vertical dip. Surface exposures <br />of this vein also range from 1 to 3 feet in width. The northeastern extension of the <br />Freiburg vein is within the boundaries of the patented Mack claim. Both the Cash and <br />Freiburg veins aze gold-silver telluride veins with sylvanite the predominant ore mineral <br />in the western part of the Cash vein and a mixture of sylvanite, petzite, and native gold in <br />the eastern portion of the Cash vein and in the Freiburg vein. This telluride <br />mineralization occurs with pyrite and a little galena and sphalerite in a gangue of horn <br />quartz. <br />Both the Cash and the Freiburg veins are narrow gold-silver telluride veins, with <br />relatively small zones of hydmthermal alteration in the surrounding wall rocks. Neither <br />vein has been deeply weathered, and primary ore can be found within several feet of the <br />ground surface, which indicates a lack of unstable sulfide mineralization. The Cash and <br />Freiburg veins do not contain substantial quantities of metallic sulfides. <br />I have examined over 100 polished sections from the veins in the Cash Mine, and have <br />determined tbe approximate mineral abundances based upon visual inspection. <br />Chalcopyrite, galena, and marcasite are present in trace or very minor quantities. <br />Sphalerite was more common than these three sulfide minerals, but only represented one <br />or two percent of the metallics observed. Pyrite was present in the polished sections in <br />volumetric percentages that ranged from two to six percent of the metallic minerals. <br />I have also performed thin section or petrographic analyses on over 50 specimens of both <br />fresh and altered granite-granodiorite from the vicinity of the Cash Mine and have not <br />detected widespread disseminated sulfides in the wall rocks.
