U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY MINERAL INVESTIGATIONS RESOURCES MAP MR-96 PAMPHLET MAP SHOWING THE LOCATION OF PRODUCTIVE LODE AND PLACER GOLD MINES IN MONTANA By David Frishman, I.E. Elliott, E.E. Foord, R.C. Pearson, and W.H. Raymond INTRODUCTION This pamphlet contains tabular information keyed to the accompanying map. Table 1 lists site names numerically keyed to the map; sites are organized by county and numbered consecutively by mining district within each county. Site numbers were assigned geographically by county with the intention of making it as easy as possible to find a particular number on the map after the site name and number have been identified in table 1. The site name listed is the one that seemed to be most commonly used and is usually the name of a mine (for lodes) or a creek or gulch (for placers). In some cases, the name is that of a claim, a group of claims, or, rarely, an exploration project. For simplicity, most of the descriptive terms by which the sites listed in table 1 have variously been known have been dropped from the list (such as "mine," "lode," "shaft," "tunnel," "deposit," "incline," "fraction," and so on.) In a few cases, the descriptive "placer," "group," "property," "dredge workings," or "prospect," label has been retained for clarity, to avoid duplication, or because the term is an integral part of the site name. Synonymous names are listed where they are known, as are the names of properties whose production was lumped with that of the property listed under "Site name." Metals and other commodities known to be present are listed in table 1 in approximate order of decreasing economic importance. Several different sources were used to determine what commodities were present including descriptions and analyses in the literature, production and grade figures, and unpublished U.S. Geological Survey chemical analyses and mineral identifications. For some small mines, and for some mines that ceased production long ago, the list of commodities present is likely incomplete. For lode mines having recorded production, not all the commodities listed were necessarily recovered some may be minor elements that are listed because they record the geochemical signature of the deposit. Industrial commodities, however (like silicon or abrasive sand), are listed only when they were produced. Silver is listed as a commodity along with gold for aT placer mines because we are confident that silver was produced and, eventually, refined, even from those placer deposits whose gold was of high fineness. Host rock type as given in table 1 is that from which the gold or gold-bearing minerals were ertracted (for disseminated, stockwork, exhalative, brecc5 pipe, and placer deposits) or the rock surrounding tl ?. gold- bearing material (for vein, replacement, and skarn deposits). An entry is included under "Asrociated igneous rocks" if there is a close spatial relationship between the host rock and an igneous body (or bodies) or some other reason to suspect a genetic relationship between the igneous rock and ore. If the host is an igneous rock and no other igneous rock is present, the rock name or names listed under "Host rock tje" are repeated under "Associated igneous rocks." Most of the lithologic terms used are taken from the literatve, and therefore the rigor of the terminology used reflects the source of the information. Rock names may b? based on detailed petrographic study, geochemistry, or field descriptions of any degree of precision. We did try, however, to use the most accurate description available. Locations are listed in table 1 to the nearest second of latitude and longitude. Mine locations were either digitized or manually interpolated from the largest scale map available at the time the work wa done,
usually the standard edition U.S. Geological Survey l:24,000-scale topographic quadrangles. Where 1:24,000 maps have not yet been published or have been published only as the Provisional Edition, l:62,500-scale maps were used. Table 1 lists a maximum of five sources of data for any property. The references listed as sources of data may not, therefore, constitute a complete list of sources. Where possible, we tried to include at least one recent reference that would allow a reader to compile a more complete list if desired. Table 2 lists both primary site names and synonymous names alphabetically and gives the site number for each so the information may be cross referenced to either the map or table 1. Primary names (those names listed as site names in table 1) are followed by "(L)" for "lode deposits" or "(P)" for "placer deposits." Other names are synonyms from the second column, table 1. Where production from more than one mine is designated by a single location symbol on the map, the names of the other mines are included in this index even though they are not true synonyms (for example, the symbol denoting the Zortman open pit mine includes historic production from the Ruby, Mint, Alabama, and other underground mines worked in the 19th and early 20th centuries). Site names like "Lower Prickly Pear Creek" are listed under both "Lower" and "Prickly," but variant spellings that would cause no confusion during an alphabetical search (for example "Nine Mile" vs. "Ninemile") are listed only once if there is only one Nine Mile mine. Duplicate names or names that might be easily confused (like the Blue Bird mine in Jefferson County and the Bluebird mine in Madison County) are followed by the name of the county to distinguish them or by the name of the mining district with which they were most commonly associated where duplicate names occur in the same county. The designation "creek" and "gulch" should be considered synonyms in table 2. Many narrow, deep canyons that were called gulches in the geologic literature of the 1800's and early 1900's are shown as creeks on modern topographic maps. We have in most cases followed the terminology used by Lyden (1948) and have not included all possible variations of the same name in the index (for example "Henderson Creek," "Henderson Gulch," "Henderson placer," "Henderson Bar"). Table 3 lists the names of mining districts alphabetically and the site numbers for the deposits each district comprises. Although some mining districts were established formally and had well-defined boundaries, many districts exist only because the name was in common use by the local miners, merchants, and other inhabitants. Historically, the term "mining district" has been used rather loosely, the boundaries of most districts are ill-defined, and the names of the districts have changed over time. The inclusion of any single locality within a specific district is in many cases a subjective decision. Table 3 lists district names that are or were commonly used in the geologic literature as well as a number of regions called "areas" that are used to group mines that lie outside of formally or informally established mining districts. Table 4 lists the names of the counties alphabetically and the site numbers for the deposits within each county.
