Location: The Red property is located west of lower Mettenpherg Creek, about 5 to 6 miles north of the junction of Mettenpherg Creek and the Malamute Fork, Alatna River. Two small claim groups, approximately 1 to 1.5 miles apart in a north-south direction are shown by Dillon and others (1981, Plate 1 [AOF 133B]); the most northerly of these claim groups is inferred (from very scant data) to correspond to the Red property. The occurrence is near the center of the claim block at an elevation of about 2,150 feet, in the NE1/4 section 2, T. 27 N., R. 24 W., of the Fairbanks Meridian. The location is accurate within 2 miles.
Geology: Almost no information is available on this property. It reportedly is a stratiform Cu-Zn occurrence in an area whose geology and geochemistry is similar to that in the Ambler District to the west (Grybeck, 1977, loc. 2). The area is underlain by Middle(?) Devonian, calcareous schist interbedded with quartz mica schist and marble (Brosge and Reiser, 1971). The Bureau of Land Management made an aerial reconnaissance of the area in the 1990's, but saw nothing to suggest the presence of mineralization (Kurtak and others, 2002). Twenty-one lode claims were staked in 1975 (Grybeck, 1977). Bureau of Land Management data indicate 8 claims were located in 1975 and abandoned in 1978 (Kurtak and others, 2002).
