Kromona Mine

The Kromona Mine is a copper, silver, and gold mine located in Snohomish county, Washington at an elevation of 3,750 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): ADIT AND 2 DRIFTS

Comment (Geology): REGION CONSISTS OF ACCRETED TERRANES OVERPRINTED BY CASCADE MAGMATISM. HOLLISTER INDICATES GOAT HAVEN DEPOSIT HAS SIMILAR METALLOGENY AND ALTERATION TO MAZAMA DEPOSIT. AGE GIVEN IS MIOCENE, BUT BATHOLITH IS SUPPOSED TO BE OLIGOCENE

Comment (Deposit): MRDS RECORDS D001418, D000688 HAVE BEEN MERGED WITH THIS RECORD AND DELETED

Comment (Location): IN SULTAN BASIN ON NORTH SIDE OF MT. STICKNEY. POSSIBLY GOAT HAVEN DEPOSIT OF HOLLISTER, ALTHOUGH GRANT INDICATES PORPHYRY COPPER MINERALIZATION IN SULTAN BASIN IS ABOUT IN SEC. 26, T29N, R10E

Comment (Commodity): ORE IS SLIGHTLY RADIOACTIVE IN PLACES

Comment (Production): TWO TON TEST SHIPMENT IN 1952. PRODUCED 102 TONS CONCENTRATE IN 1954. SMALL PRODUCTION IN 1953, 1955.

Comment (Development): NO W PRODUCTION

Comment (Deposit): ORE IN LENSES IN NORTHEAST-TRENDING STRUCTURES AT CONTACT BETWEEN QUARTZ DIORITE AND METASEDIMENTARY ROCKS. MANY QUARTZ VEINS CONTAINING SULFIDES
