General comments

Subject category Comment text
Deposit ADITS ARE LOCATED IN THE MINERALIZED COMBINED METALS BED WHICH HERE CONSISTS OF AN OXIDIZED BEDDED REPLACEMENT DEPOSIT 3-20 FT THICK WITH A STRIKE LENGTH OF 300 FT. A NE-STRIKING LAMPROPHYRE DIKE CUTS THE ROCKS AT THIS OUTCROP. THE MINERALIZED ROCK CONSISTS OF SILICIFIED LIMESTONE WITH ABUNDANT FE-MN OXIDES. OLD COMPANY SURFACE ASSAYS OF THIS OUTCROP SHOW TRACE AMOUNTS OF AG, 0.2% PB, 2.2% ZN, AND ABOUT 9% MN. ALSO, NUMEROUS PROSPECTS LIE ALONG NW-AND NE-STRIKING VEINS ON THE RIDGE ABOVE THE ADITS.
