The Nelson prospect is on Bering Straits Native Corporation selected lands.
Location: The Nelson prospect is in Steep Creek, a tributary of Gold Bottom Creek, at an elevation of about 1,050 feet. It is about 0.7 mile south-southwest of Mount Distin. The prospect is locality 13 of Hummel (1962 [MF 248]), locality 23 of Cobb (1972 [MF 463], 1978 [OFR 78-93]); it is shown on figure 17 of Cathcart (1922).
Geology: The Nelson zinc-lead prospect contains sphalerite, galena, and pyrite in veinlets subparallel to layering in marble and in stockwork-like fracture zones; it includes a galena veinlet 2 inches thick (Mertie, 1918 [B 662-I, P. 425-449]; Cathcart, 1922). When the prospect was visited by Cathcart in 1920, mineralization was exposed over about a 6-foot width in an open cut near a contact of marble and mica schist; the schist had a strike of N 15 W and dipped 18 degrees west. The marble was bleached in the mineralized zone. An adit, reportedly 55-feet long (Mertie, 1918 [B 662-I, p. 425-449]), was caved and inaccessable to Cathcart (1922). The prospect was visited in 1995 by C.C. Hawley, but the exposures were badly sloughed and the nature of the mineralization could not be observed. The Nelson propect is within the main marble mass of Mount Distin where thin mica schist layers occur (Hummel, 1962 [MF 248]; Bundtzen and others, 1994). Layering in the marble and the schist is generally north-dipping and the prospect is about one-half mile south of the east-west axis of the Mount Distin syncline of Hummel (1962 [MF 248]).
Workings: Developments included a 55-foot adit, an open cut, and several pits; all are now badly sloughed. The site does not appear to have been active since before 1920. Hummel and Chapman (1960) did not find anomalous zinc in stream sediment samples collected from Steep Creek about a mile below the Nelson prospect.
Age: Probably mid-Cretaceous or younger; appears to postdate regional metamorphism of mid-Cretaceous age.
Alteration: Marble was bleached at the prospect.

Commodities (Major) - Pb, Zn
Development Status: Undetermined
Deposit Model: Carbonate-hosted, lead-zinc deposit.
