Thirty-two percussion holes in CRB revealed silver-cadmium mineralization (14.3ppm Ag/5.1ppm Cd) near a large moderately dipping fault. The mineral occurrence is hosted on private land and is situated five miles north of a gold prospect hosted in the same geological environment. The gold prospect was explored via a 60 foot shaft and short drift. Ag-Cd closely correlated in the ratio of three parts Ag to one part Cd, which may suggest an intermetallic alloy of the composition Ag3Cd. (A new gold-lead intermetallic alloy, AuPb4, equally intergrown with native lead, was identified via microprobe on a property further north.) A dozer cut exposed 30 feet of the fault width; drilling indicates about a 60 foot width. The deepest hole, 74 feet in vertical depth, was collared directly over the exposed fault. It penetrated 16 feet (apparent width, 10-12 feet true width) of anomalous lead mineralization at the 48-64 foot interval adjacent to the footwall contact. Beyond that point the yellowish altered, mineralized rock passed into black unaltered, unmineralized rock. The fault zone is marked by gray clasts and gouge and is anomalous in selenium (Chemex). Manganocalcite veinlets lace some of the clasts. All four drill holes collared along the strike of the fault intersected an iron-cadmium rich gossan. A surficial manganese halo partially envelopes the fault. The 14-16 foot flowtop adjacent to the fault is anomalous in Ag, Cd, Hg, Cu, Pb, Zn, Mn, Se, Sb and U (56.2ppm INAA). The drill holes intersected interflow structures anomalous in Cu-Sb at the 14-16, 24-26, 40-42, and 72-74 foot intervals. The exposed hanging wall is bleached and argillically altered. One of the holes recovered quartz crystals and mica at the 14-16 foot Cu-Sb horizon. A 60 foot percussion hole showed a consistent stepwise increase in sulfur values extending to the bottom of the hole. The high selenium noted in the fault may reflect an oxidative signature of a sulfide zone at depth.
