This occurrence is one of several small skarn zones at granitic contacts through out the Ambler River quadrangle (Degenhart and others, 1978). Located in the Noatak National Preserve.
Location: Located in the Baird Mountains on ridge near Peak 3475 in T. 25 N., R. 3 E., Kateel River Meridian. Shown as locality 6 in Mayfield and Grybeck (1978) and is accurate to within 2000 ft. (600 m).
Geology: Disseminated pyrite, galena, fluorite and malachite in Kalvich pluton along contact zone. Deposit is 1 mi (1.6 km) in strike length. Visual estimate of 1% galena and 1% fluorite in granitic rock along north margin of pluton. About 8 sq. mi. (13 sq km0 of the surrounding area is geochemically anomalous in Pb and Zn. n. The Kalvich pluton is in contact with black siltstone interbedded with marble and quartz-mica schist to the north and east and with gray to black marble of the Skajit limestone to the south and west. The northern margin of the pluton is a migmatitic contact zone containing moderately anomalous Pb, Zn, Mo, Sn and W (Degenhart and others, 1978, p. 340-350).
Workings: A representative bedrock chip sample from a 100 ft. by 7 ft. (33 m x 2 m) area of highly foliated fine grained intrusive rock yielded 86 ppm Cu, 2000 ppm Pb, 94 ppm Zn, 53 ppm Mo, 14 ppm Ag, 34 ppm Sn, 1400 ppm F (Degenhart and others, 1978, p. 340-350).
Reserves: The possibility of even a small tonnage of economic grade material being discovered is remote.
