The Niccolia (also Niccola, Nicholia, Nicolia) mining district, bound on the west, south and east by the Continental Divide which forms the Idaho, contains the southewestern corner of Montana. The area is extremely isolated, accessed by one dirt road and a system of pack trails.
Geologically the district is composed of folded and faulted upper Paleozoic sediments (Sahinen 1935).
There is no recorded mineral production in this area. Nor is there any discussion in the mining literature of any mineral exploration in the district.
BOUNDARIES OF THE DISTRICT
Sahinen (1935) states that the district is at the headwaters of Nicolia (sic) Creek about 20 miles southwest of Dell, a small community on Interstate 15 and a station on the Oregon Short Line (now Union Pacific RR). He also mentions that the district is shown on a map of Beaverhead County published by the George Engineering Company of Dillon, Montana. Figure 1 is the general area or district described by Sahinen (1935).
