General comments

Subject category Comment text
Deposit THE TYPE OF DEPOSIT IS UNKNOWN. OTHER DEPOSITS IN THE DISTRICT INCLUDE PORPHYRY COPPERS AND POLYMETALLIC VEINS. IT WOULD BE UNUSUAL TO FIND PT IN A POLYMETALLIC VEIN BUT ALSO UNUSUAL TO FIND PB IN A MAGMATIC SEGREGATION DEPOSIT. POSSIBLY THERE WERE TWO STAGES OF MINERALIZATION, PT DEPOSITED WITH THE ULTRAMAFIC HOST ROCKS AND A LATER OVERPRINT OF THE AG, PB, AU MINERALIZATION
