| Deposit | THREE TYPES OF DEPOSITS WERE WORKED: PLACER, BRECCIA ZONE AND FISSURE VEIN. THE PLACER CONSISTED OF ARGENTIFEROUS GALENA FLOAT RANGING IN SIZE FROM PEBBLES TO BOULDERS. THE BRECCIA ZONE CONSISTED OF BLACK, SHALY GOUGE AND BRECCIA CONTAINING PYRITE AND CHALCOPYRITE, MOST OF THE GOLD APPARENTLY OCCURRING WITH THE CHALCOPYRITE. THIS ZONE, OCCURRING ALONG THE LIVE YANKEE FAULT, WAS CHIEFLY VALUABLE FOR LEAD, SILVER AND GOLD, WITH SOME COPPER PRODUCTION. THE BELOROPHON FISSURE AND OTHER NE TRENDING FISSURES YIELDED ORE CONTAINING PYRITE, GALENA, SPHALERITE AND TETRAHEDRITE WITH BARITE GANGUE AND YIELDING CHIEFLY LEAD, ZINC AND COPPER. |
