Comments on the location information

  • THIS PROSPECT IS LOCATED SOUTH OF THE RED CLOUD RIVER, 2 3/4 MILES SOUTHWEST OF PYRAMID MOUNTAIN IN SEC. 35. T. 27 S., R. 21 W., OF THE SEWARD MERIDIAN (BERG AND COBB, 1967, FIGURE 15, LOCALITY 8; ROSE AND RICHTER, 1967, FIGURE 1, LOCALITY 1; COBB, 1972, MF 460, LOCALITY 13; MACKEVETT AND HOLLOWAY, 1977, LOCALITY 13). SITE LOCATION IS ACCURATE TO WITHIN SEVERAL HUNDRED FEET.

Comments on the workings information

  • AT THE TIME OF SEITZ'S VISIT IN 1963 THE SHOWINGS HAD BEEN EXPOSED BY OPEN CUTS AND PITS. SIX CHANNEL SAMPLES RANGED IN GRADE FROM 0.06 TO 1.75 PERCENT TUNGSTEN OXIDE.

Deposit THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
Deposit SCHEELITE OCCURS AS MINUTE DISSEMINATED GRAINS AND VEINLETS IN SILICEOUS ZONES IN CRETACEOUS GRAYWACKE, AS THIN COATINGS ON THE EDGES OF QUARTZ VEINS, AND IN FRACTURES. THERE ARE ABUNDANT QUARTZ-SCHEELITE VEINS IN THE VICINITY OF THE DISSEMINATED SCHEELITE. THE DISSEMINATED SCHEELITE IS GENERALLY CONFINED TO POD-SHAPED BODIES UP TO SEVERAL FEET THICK AND ONLY A FEW FEET LONG. ONE MINERALIZED ZONE, HOWEVER, IS APPROXIMATELY 100 FEET IN LENGTH. SEITZ (1963) LOCATED 15 SEPARATE SCHEELITE SHOWINGS TRENDING ROUGHLY N. 45 E. GENERALLY PARALLEL TO BEDDING. THESE OCCUR WITHIN AN AREA MEASURING APPROXIMATELY 300 BY 1600 FEET. ROSE AND RICHTER (1967) CITE A PERSONAL COMMUNICATION FROM JASPER, WHO FOUND 4 ADDITIONAL SHOWINGS, THUS EXTENDING THE MINERALIZATION AN ADDITIONAL 2000 FEET TO THE SOUTHWEST. FOUR CHANNEL SAMPLES OF DISSEMINATED SCHEELITE COLLECTED BY SEITZ ASSAYED 0.06 TO 0.56 PERCENT TUNGSTEN OXIDE. TWO SAMPLES COLLECTED BY JASPER (CITED BY ROSE AND RICHTER, 1967) ASSAYED 1.75
Deposit AND 0.28 PERCENT TUNGSTEN OXIDE OVER 35 AND 42 INCHES. THE ORIGIN OF THE DISSEMINATED SCHEELITE IS UNKNOWN ALTHOUGH IT HAS BEEN SUGGESTED (SEITZ, 1963) THAT IT AND THE SCHEELITE-QUARTZ VEINS ARE SOMEHOW RELATED TO NEARBY INTRUSIVE BODIES OR TO OTHER UNEXPOSED PLUTONS. KODIAK EXPLORATION SENT A SAMPLE FROM THIS AREA OR FROM THEIR CORNELIUS CREEK PROPERTY (KD026) TO WAH CHANG CORPORATION FOR ANALYSIS AND EXAMINATION. THEY IDENTIFIED THE SO-CALLED SILICEOUS MATERIAL CONTAINING THE DISSEMINATED SCHEELITE AS TACTITE OR SKARN (JASPER, 1955).
