|Location and accuracy||This occurrence is at an elevation of about 3,400 feet, approximately 7 miles due north of the east end of Reds Lake (sec. 13, T. 36 N., R. 5 W., of the Fairbanks Meridian). This site corresponds to the northwesternmost of three unnamed prospects shown as loc. 85 in DeYoung (1978) and is included with loc. 50 in Schmidt (1997). The location is accurate within a 1/2-mile radius.|
Geologic descriptionSchmidt (1997, loc. 50) includes this occurrence with three, presumably similar, occurrences. They are described as quartz veinlets containing malachite-azurite plus or minus pyrite, chalcopyrite, and pyrrhotite in the Silurian and Devonian Skajit(?) Limestone and overlying siltstone and limestone (Beaucoup Formation?). The geologic map indicates that this occurrence is near a thrust contact between Devonian(?) purple, green, and red chloritic slate and phyllite and the Devonian(?) Skajit Limestone (Brosgé and Reiser, 1964). No other information is available.
