Geologic information

Identification information

Deposit ID 10308737
Record type Site
Current site name Tuttle Creek

Geographic coordinates

Geographic coordinates: -166.35246, 65.9373 (WGS84)
Relative position Tuttle Creek is a west-flowing drainage with headwaters on the north flank of Ear Mountain, an isolated upland reaching 2,329 feet elevation in the north-central Teller D-3 quadrangle. The headwaters of Tuttle Creek are in the area straddling the contact between the Ear Mountain granite stock and metacarbonate rocks (Sainsbury, 1972). North Hill, a flat-topped hill reaching 1,642 feet elevation on the north flank of the Ear Mountain upland, is the location of the principal lode prospect (TE060) in the area. This is locality 49, 50, and 52 of Cobb and Sainsbury (1972). Cobb (1975) summarized references to this locality under the name 'Tuttle Cr.'.

Comments on the geologic information

  • Geologic Description = Tuttle Creek and its headwaters drain a mineralized area straddling the contact between the Late Cretaceous Ear Mountain granite stock (76.7 +/- 2.9 my; Hudson and Arth, 1983, p. 769) and an impure metacarbonate sequence, with some metapelitic rocks, of unknown but probable Paleozoic age. Both overburden and gravel vary from a few feet to 15 feet in thickness. The tin content of the gravels varies from a trace to 1.28 pounds per cubic yard. The average tin content of the main drainage, as determined by 45 churn-drill holes, is 0.2 pounds per cubic yard (Mulligan, 1959, p. 23). The mining section along this part of the drainage averaged 7 feet in thickness. Tin in heavy mineral concentrates is present as cassiterite; other heavy minerals that were identified include monazite, zircon, axinite, scheelite, magnetite, and danburite (Killeen and Ordway, 1955). Some heavy mineral concentrate contained 0.23% eU; only traces of gold are reported.
