General comments

Subject category Comment text
Deposit GOLD, STIBNITE, ARSENOPYRITE, SCHEELITE, AND PYRITE BEARING LODE IN STRINGERS OR VEINLETS OF QUARTZ CUTTING SILICIFIED SCHIST. IN MANY PLACES COUNTRY ROCK CLOSE TO VEIN IS HEAVILY IMPREGNATED WITH SULFIDES, ESPECIALLY WHERE THE WALL ROCK IS SOMEWHAT CALCAREOUS. FREE GOLD VISIBLE IN BOTH QUARTZ AND STIBNITE. SOME OF STIBNITE IS BLADED, SOME IS MASSIVE, AND SOME IS DISSEMINATED.
