| Deposit | THE COUNTRY ROCKS IN THE GENERAL AREA OF THE BERG PROSPECT (KOCH, 1996, 1997) ARE MESOZOIC OR PALEOZOIC PELITIC SCHIST AND PARAGNEISS, AND SUBORDINATE AMPHIBOLITE AND MARBLE. AMBIGUOUS EARLY DESCRIPTIONS SUGGEST THAT THE PROSPECT IS AN AURIFEROUS LODE DEPOSIT. NO OTHER GEOLOGICAL INFORMATION ABOUT THIS PROPERTY HAS BEEN MADE PUBLIC. |
| Deposit | THERE IS LITTLE GEOLOGIC INFORMATION ABOUT THE BERG PROSPECT. EARLY REPORTS DESCRIBING IT (CHAPIN, 1916, P. 78; 1918, P. 75) INCLUDE REFERENCES TO THE COPPER KING PROSPECT (BC002). PARTS OF SOME OF THE EARLY DESCRIPTIONS OF THE BERG PROSPECT ARE AMBIGUOUS, AND MAY ACTUALLY REFER TO A DEPOSIT IN BERG BASIN, TO THE WEST IN THE ADJOINING PETERSBURG QUADRANGLE. |
