Unnamed Occurrence (ARDF - SK027; in the Takshanuk Mountains), Skagway District, Juneau District, Haines Borough, Alaska, USA

This page is currently not sponsored. Click here to sponsor this page.
Location: This occurrence is near the top of Peak 4920 in the Takshanuk Mountains; it is approximately 1.9 miles northwest of Tukgahgo Mountain in the NW1/4, section 33, T. 29 S., R. 58 E. of the Copper River Meridian. It is shown as number 28 by Berg and others (1981); mineral occurrence number 5 on sheet 1 of Redman and others (1984); and number S045 by Wells and others (1986).
Geology: Redman and others (1984) describe this occurrence as, 'Malachite-stained quartz veins that cut diorite and carry chalcopyrite and bornite.' The veins trend N25E and dip 55E. They can be traced for at least 330 feet and occupy a zone 80 feet wide. A sample of mineralized vein contained 5.73% copper and 21 ppm silver. The mineralization is near a metabasalt body that is probably a pendant within the mid-Cretaceous, Mount Kashagnak pluton. This is probably the same occurrence referred to by Buddington and Chapin (1929) who report bornite and hematite from quartz veins about 10 miles northwest of Haines.
Age: Mid-Cretaceous or younger based on age of the Mount Kashagnak pluton (Redman and others, 1984).

Commodities (Major) - Ag, Au, Cu
Development Status: None
Deposit Model: Quartz sulfide veins (Cox and Singer, 1986; model 36a or 22c),
