Deposit PROSPECT IS PART OF THE MAIN DEPOSIT ON WHICH THE NEVADA PLACER GYPSUM CLAIM AND SATIN SPAR CLAIM ARE LOCATED. THE DEPOSIT IS 100 TO 200 FT. THICK AND HAS BEEN OFFSET BY TRANSVERSE FAULTS. THE DEPOSIT CONSISTS OF BEDDED GYPSUM AND LIMESTONE; GYPSUM GRADES WITH DEPTH TO ANHYDRITE. THE GYPSUM UNIT CROPS OUT IN THE MINE AREA AND TO THE EAST AND WEST OF THE WORKINGS. THIN-BEDDED LIMESTONE FORMS -BOTH WALLS OF THE GYPSUM UNIT. THESE ROCKS HAVE VARIABLE ATTIT-UDES, BUT GENERALLY TREND NE TO E WITH DIP 35-60 NW TO N. THE -GYPSUM UNIT HAS A HORIZONTAL WIDTH OF 125 FT, BUT ITS TRUE THI-CKNESS IS UNKNOWN BECAUSE OF DEFORMATION. THE GYPSUM IS THOROU-GHLY BRECCIATED AND BEDDING IS SELDOM VISIBLE. A FEW MASSES OF- THIN-BEDDED LIMESTONE ARE PRESENT WITHIN THE GYPSUM UNIT. THE-SE ARE UP TO 6 FT ACROSS WITH VARIABLE STRIKE AND DIP AND HAVE- SHARP BUT IRREGULAR CONTACT WITH THE GYPSUM.
