Location: Fairbanks County, Alaska, United States, North America
Lat / long: 64.86266, -147.99295
dep_id: 10308828
mrds_id: A015279
Commodity type: metallic
Major mineral: Gold
Operation type: Unknown
Development status: Past Producer
ore: Arsenopyrite, Gold, Jamesonite, Stibnite
alteration: A surface oxidation zone is present at both the Ryan and Curlew shears and varies in depth from 150 feet to more than 300 feet. There has been extensive sericitic alteration along shears and fractures within the quartz monzonite intrusion. At least three alteration assemblages have been identified: quartz-muscovite-siderite, quartz-muscovite-chlorite, and silicification (Ryan Lode Mines, Inc., unpublished report, 1996).
