Comments
Comment (Geology): ARGILLITE AND GREENSTONE OF PROBABLE LATE PALEOZOIC AGE ARE INTRUDED BY DIKES OF THE PORPHYRITIC GRANODIORITE OF MANILIA CREEK (PARDEE, 1918; GULICK AND KOROSEC, 1990, GEOL. MAP).
Comment (Production): REPORTED TO HAVE PRODUCED, BUT THE AMOUNT IS UNKNOWN (HUNTTING, 1956, P. 366).
