Abstract

The northern Black Hills of South Dakota and Wyoming contain a large number of mineral deposits that range in age and type from Quaternary placers to Early Proterozoic or Late Archean pegmatites. Classification of the different deposits according to age, metals present, and structure of the deposits (DeWitt et. al., 1986) allows the delineation of twenty-two metallic mineral districts, which contain 303 mines or mineral deposits. These districts and mines are shown on four maps across the northern Black Hills. The mines or mineral deposits are listed numerically and alphabetically in Tables 1 and 2. These metallic mineral districts differ significantly from conventional mining districts, which generally had geographic or political boundaries and could contain mineral deposits of differing age and genesis. In contrast, metallic mineral districts are defined by geologic criteria and are classified by age of mineralization, metals present, and structure of the deposit. Therefore, one district contains only one age and type of mineral deposit.

Metallic mineral districts across the northern Black Hills are present in four major clusters: in the Bear Lodge Mountains of Wyoming (Fig. 1); at Tinton on the South Dakota-Wyoming border (Fig. 2); in the Lead area of South Dakota (Fig. 3); and in the Galena area of South Dakota (Fig. 4). Mines and mineral deposits on all figures are given a letter designation (C, T, etc.) and a plotting symbol (filled circle, filled square, etc.) that indicates the deposit type. Plotting symbols are consistent from one figure to the next.
