The Discovery Creek prospect is located within Doyon, Ltd. selected or conveyed land. For more information contact Doyon, Ltd., Fairbanks, Alaska.
Location: The Discovery Creek prospect is in the upper drainage of Discovery Creek near the junction of its headwater forks. Discovery Creek is a small north tributary of the lower Fortymile River about 3 miles west of the Canadian border. The coordinates are the approximate center of the prospect at the southeast corner of section 23, T. 7 S., R. 33 E., of the Fairbanks Meridian. The location is accurate. The Discovery Creek prospect is located within Doyon, Ltd. selected or conveyed land.
Geology: The rocks along Discovery Creek are Paleozoic quartz-biotite schist and gneiss, chlorite-garnet-mica schist, and marble (Foster, 1976; Dashevsky and others, 1986). Small Mesozoic or Tertiary biotite granite and quartz monzonite stocks are near the mouth and in the headwaters of Discovery Creek, and Mesozoic pyroxenite or hornblendite crops out near the mouth of the creek (Foster, 1976). A sample of ferricrete float from Discovery Creek contains 1,350 ppm copper and 600 ppm zinc. Low-grade chalcopyrite mineralization in calc-silicate float is associated with anomalous copper in soil on the east side of the upper creek. A soil sample from the west side of the valley contained 460 ppm lead, 352 ppm zinc, and 3.2 ppm silver. A weak REM and VLF anomaly trends northwest in an area without a surface geochemical anomaly. WGM Inc. conducted reconnaissance mapping and soil sampling in the Discovery Creek area in 1976 (Dashevsky and others, 1986). In 1977, WGM Inc. sampled soil on a grid and conducted REM, VLF, and magnetometer surveys in the area.

Alteration: Samples of mineralized ferricrete and calc-silicate float were collected in the Discovery Creek area.
