Seward Peninsula airborne electromagnetic survey, Kigluiak, Bendeleben, and Darby Mountains, Geophysical Report 2024-2, covers parts of the Teller, Bendeleben, Nome, and Solomon 1:250,000-scale U.S. Geological Survey (USGS) quadrangles on the Seward Peninsula north of Nome, Alaska. Time-domain electromagnetic data were collected with the SkyTEM 306HP system, which was towed by a helicopter, from September 8 to October 3, 2023, and from June 5 to July 18, 2024. A total of 4,330-line kilometers (km) were collected covering 4,817 km2. The survey was flown with semi-parallel lines spaced approximately 1 km apart and oriented perpendicular to regional geologic strike. Electromagnetic data were used to create resistivity...

This dataset contains 99 electron microprobe analyses of cassiterite, chalcopyrite, galena, pyrite, sphalerite, and tetrahedrite from seven Sheep Creek drill core samples and one outcrop; and a table that describes the textures, mineralogy, and rock type of 15 thin sections of Sheep Creek drill core and observations from our study and from drill core logging by industry. These data were used to compare this prospect with others in the Bonnifield district. The dataset also contains tables of sensitive high-resolution ion microprobe (SHRIMP) U-Pb zircon dates, zircon characteristics (crystal shape, external morphology, internal features, color, aspect ratio, and cathodoluminescence zoning), and 139 U-Th-Pb analyses...
