Location: This lode prospect is at the base of the east slope of the Sunde Creek valley, about 1.5 miles downstream from the bridge where Tofty road crosses Sunde Creek (Thomas, 1958 [McIntyre tin prospect]). The site is in the southwest quarter of section 22, T. 3 N., R. 15 W., of the Fairbanks Meridian. The location is accurate within 500 feet. This site corresponds with the site for McIntyre, U.S. Bureau of Land Management MAS number 0020480125.
Geology: The country rocks in the area of Hot Springs Dome consist of Tertiary (58 Ma) biotite granite, Cretaceous, predominantly marine, sandstone, shale, and siltstone, and a hornfels zone peripheral to the granite (Chapman and others, 1982; Reifenstuhl and others, 1998). The McIntyre prospect is in the sedimentary rocks just outside the hornfels zone (Reifenstuhl and others, 1998). The McIntyre prospect is on a 500-foot by 50-foot area of limonite gossan in talus near the contact of the Hot Springs Granite, which is considered to be prospective for tin mineralization (Thomas, 1958 [McIntyre tin prospect]). The limonite probably is the result of of oxidation of pyrite. A shallow trench, now caved, was excavated in rubble at the base of the talus slope. Thomas collected grab samples from the trench dump and chip samples from above the talus, but reported no analytical results.
