| Basis for focus area |
Outline of Trout Creek district from Krahulec (2018b). Historical production of W and recognized ore grade Be. |
| Identified resources |
Historical production of lead, silver, tungsten, and zinc. |
| Production |
93 t Zn-Pb-Ag ore and 7890 lbs WO3 (Krahulec, 2018b). |
| Status |
Past mining. |
| Estimated resources |
Unknown. |
| Geologic maps |
Rodgers (2020), scale 1:50,000. |
| Geophysical data |
Inadequate Rank 4 aeromagnetic coverage. |
| Favorable rocks and structures |
Neoproterozoic rocks have been intruded and domed by a series of alaskite sills. The alaskite primarily occurs as sills and varies from coarse-grained pegmatite to aplite, is commonly foliated along its contacts, and is principally composed of quartz, potassium feldspar, muscovite, garnet, and locally biotite (Nutt and others, 1990; Krahulec, 2018b). |
| Deposits |
Trout Creek, Gold Bond, Apex. |
| Evidence from mineral occurrences |
UMOS (Utah Geological Survey, 2021); Krahulec (2018b). |
| Geochemical evidence |
Geochemical sampling shows sporadic ore-grade W, Zn, and Be, and geochemically anomalous Au, Ag, Bi, Cd, Cu, F, Pb, Mo, and Sn (Thomson, 1973; Hannigan, 1990; Nutt and others, 1990). |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
See Krahulec (2018b), Nutt and others (1990). |
| Comments |
Enrichment of some critical commodities (for example, Sb, As, Ga, Ge, In, Mn, Nb, Sc and Ta) inferred from the mineral system/deposit type table (Hofstra and Kreiner, 2020) and require further testing. |
| Cover thickness and description |
Unknown. |
