| Deposit | IRON OXIDE MINERALS OCCUR IN QUARTZ VEIN MATTER AND SILICIFIED ROCK ALONG A FAULT ZONE CUTTING OLIVE PHYLLITE, WORKINGS ARE QUITE SHALLOW, ENTIRELY IN THE OXIDIZED ZONE. STOPING WAS DONE ALONG THE FAULT, UP TO 1 M WIDE. BRECCIATION FOR SEVERAL METERS AWAY FROM THE FAULT IS COMMON. VEIN QUARTZ IS SPOTTY, OFTEN CRUSHED. SERICITE (GREEN) OR ILLITE OCCURS IN THE CRUSHED PHYLLITE IN THE CENTRAL PART OF THE FAULT ZONE. THE WORKINGS EXAMINED HERE ARE ALONG A NORTH-TRENDING LINE OF PITS, ADITS, AND SHAFTS EXTENDING FOR OVER 1.5 KM N-S. EXAMINATION OF PITS TO THE SOUTH INDICATES THAT THIS THRUST FAULT CONTINUES AND IS THE MINERALIZED STRUCTURE AT THE INCLINED SHAFTS IN N W 4 SEC 18, T 34 N, R 40 E. THE STRUCTURE PROBABLY ALSO CONTINUES TO THE NORTH ALONG THE LINE OF WORKINGS IN W 2, SEC 7, T 34 N, R 40 E. THE MORE EXTENSIVE WORKINGS ARE IN NW 4, SEC 18. |
