| Deposit | The Schwartz Tunnel is at or near the basal contact of the Pioche Shale with the Prospect Mountain Quartzite. Some of the vein material on the adit dump above the Schwartz tunnel is pegmatitic with coarse white mica and coarse terminated quartz crystals in vugs. Below the adit dump is Pioche Shale. The adit above the tunnel displays a replacement horizon in one of the basal limestone units of the Pioche Shale. The limestone is silicified and now displays a typical tactite mineral assemblage of diopside, calcite, and epidote with some fluorite, pyrite and chalcopyrite throughout. Sphalerite is also present. The altered horizon at the mouth of the adit is reddish-brown silicified limestone with polka dot appearance from algal girvanella. This horizon is capped by gossan, which can be followed for 100 ft or more to the SW. At the ridgecrest SW of the Schwartz workings is an old shaft and several dozer trenches. The replaced horizon recurs here. A coarse, bladed, greenish white mineral (wollastonite or tremolite) occurs on the vein selvages. Host rock is bedded calcareous quartzite, limestone, or limy shale, striking N-S, dipping 15-36E. Limey shale and limestone located 100 feet above the tunnel are altered to tactite. A stockwork of quartz veins outcrops continuously with a strike of N70E and dip of 13SE. Southwest of the tunnel, pyrite and chalcopyrite occur in veinlets, pods, and replacement of algal spheroids within the replaced horizon. Gossan is abundant in the dump material. |
