Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Location): HUNTTING'S DESCRIPTIVE INFORMATION DOES NOT FIT WITH HIS CADASTRAL LOCATION. HIS INDICATION THAT THE DEPOSIT LIES IN THE SILVER CREEK DISTRICT SUGGESTS THE CADASTRAL LOCATION IS NOT APPROPRIATE. CORRECT LOCATION SHOULD PROBABLY BE T. 28 N.

Comment (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
