Location and accuracy The site is based on early descriptions of several mineral prospects and minor placer gold production on Lucky Six Creek (Schrader 1904). The prospects apparently were not visited by Schrader who based their location on reports by prospectors. Their exact location remains undetermined. The coordinates are that of a sample with metal values collected by Kurtak and others (2002). Their sample site is about 1.7 miles north of Gull Pass and about 0.5 mile east of the center of section 33, T. 26 N., R. 18 E. Kurtak's location is accurate but the old Schrader location is vague. Also see ARDF SP012, Lucky Six Creek, which is nearby and may refer to the same site.

Geologic setting

Geologic description

Based solely on information from prospectors, Schrader (1904) reported that six or more quartz veins, 10 to 75 ft. thick, occur in a belt 6 miles long. Samples given to him by prospectors contained pyrite, chalcopyrite, bornite, malachite, and stibnite. The veins were reported to have been discovered in 1902-1903. The country rock in the area is marble interlayered with chlorite schist of the Devonian and Silurian Skajit Limestone (Nelson and Grybeck, 1980). Kurtak and others (2002) collected a sample of quartz-carbonate float with tetrahedrite(?), malachite, and azurite in Lucky Six Creek about 1.7 miles north of Gull Pass. The sample contained 43 parts per million (ppm) silver, 672 ppm arsenic, and 3,580 ppm antimony.
