Comments on the production information

  • SPECIFIC INFORMATION LACKING. PRODUCTION THOUGHT TO BE VERY SMALL, INTERMITTENT, COTTAGE INDUSTRY TYPE.
  • RICH POCKETS FOUND, POCKETS HAD $500.00 TO $600.00 IN NATIVE GOLD AT $20.00 PER OUNCE

Comments on the reserve resource information

  • POSSIBLY SOME MINOR AMOUNT REMAINS

Comments on the workings information

  • ONE SHAFT BUT NUMEROUS PITS MAKE UP EXTENSIVE SURFACE WORKINGS; ADJACENT SMALL STREAM TO WEST WAS PLACERED
  • INFORMATION LACKING. NEED ON-SITE INSPECTION.

Comments on development

  • GOLD DISCOVERED SHORTLY BEFORE 1853, AND WORKED IN INTERVALS TO 1882 WITH SHAFT SUNK TO ABOUT 18M; WORKED IN 1890 AND SHAFT DEEPENED ANOTHER 7.5M; ACTIVE BETWEEN 1895 AND 1905 ON SURFACE WITH 20-STAMP MILL ERECTED AND SHAFT RETIMBERED
  • PROSPECT IS SOUTHERN MOST PART OF SPRUCE PINE MICA DISTRICT. THIS DISTRICT ACTIVE SINCE 1868 AND A MAJOR MICA PRODUCER. THIS LOCALITY TAKEN AS A "LITTLE DEVELOPED PRODUCER" BASED ON INFORMATION AVAILABLE. ORE MATERIAL AVAILABLE ON SURFACE. NO FORMALIZED DEVELOPMENT REQUIRED.
