The Quartz Creek is a copper, gold, silver, and molybdenum mine located in King county, Washington at an elevation of 1,801 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.

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 (Geology): GRANT (1969) REFERS TO HOST ROCKS AS QUARTZ CREEK STOCK OF THE SNOQUALMIE BATHOLITH. DEPOSIT IS NEAR WEST-CENTRAL CONTACT OF SNOQUALMIE BATHOLITH. CALLIGAN FORMATION AND MOUNT GARFIELD VOLCANICS IN GRANT ARE PROBABLY EQUIVALENTS OF WESTERN MELANGE BELT AND UNNAMED VOLCANIC ROCKS OF TABOR AND OTHERS, RESPECTIVELY.
Comment (Workings): 3 ADITS, WINZE, SHAFT
Comment (Deposit): DEPOSIT HAS BEEN GIVEN THE INFORMAL NAME OF A BRECCIA PIPE CU DEPOSIT, FOR WHICH THERE IS NO PUBLISHED MODEL. TWO ELIPTICAL MINERALIZED BRECCIA PIPES, DIMENSIONS ARE FOR EAST PIPE. A LOW-GRADE PORPHYRY SYSTEM MAY BE PRESENT AT DEPTH
Comment (Production): SMALL PRODUCTION BETWEEN 1951 AND 1957. ONE LOAD OF CONCENTRATES REPORTEDLY SHIPPED IN 1952
Comment (Development): DEPOSIT HAS BEEN DRILLED SEVERAL TIMES SINCE 1957.
Comment (Reserve-Resource): INDICATED RESERVES ARE ESTIMATED AT 56,000 TONS AT 5.5% CU, 2.5 OZ/TON AG; 905,000 TONS AT 1.1% CU (DERKEY, 1990).
Comment (Deposit): MRDS RECORD W017919 HAS BEEN MERGED WITH THIS RECORD AND DELETED
Comment (Commodity): COMMODITY DISTRIBUTION IS ZONED. SLIGHT RADIOACTIVITY RECORDED AT ONE LOCATION. PB ISOTOPE DATA IS AVAILABLE IN CHURCH AND OTHERS
Comment (Reserve-Resource): CONSERVATIVE ESTIMATES ARE GIVEN
