Mineral Subdistricts and Individual Mines

Individual mines within the IKFD are grouped into subdistricts and discussed below. The individual mines were sometimes named after the mining company, but other mines were given various monikers, such as Black Jack, Interstate, Good Hope, Empire, and Eureka. Some veins extended across several property lines and had several shafts. For example, when a new shaft was sunk along the southwest extension of the Empire Vein (Empire Mine) on the Redd property, the new shaft and the mine became known as Redd. Portions of the following information were extracted directly from ISGS publications and maps(Denny et al. 2008a, 2010, 2011, 2013; Denny and Counts 2009; Seid et al. 2013a, 2013b; Denny and Seid 2014; Devera et al. 2016). Additional information may be found in 7.5-minute quadrangle geologic maps and reports available at the ISGS (http://www.isgs.illinois.edu/maps/isgs-quads).

During the summer of 2018, the authors gained access to the files left in the field office of Ozark-Mahoning in Rosiclare. Ozark-Mahoning ceased mining operations in the district in about 1996. The Hastie Mining and Trucking Company purchased the Ozark-Mahoning property and records several years ago, and Hastie Mining allowed the ISGS to scan the geologic records. The records contained more than 1,000 drill logs, hundreds of mine maps, and hundreds of geologic cross sections, drill profiles, and reserve calculations. The paper maps and cross sections were scanned at 400 dpi (.tif images) to retain the proper map scale, whereas the drill logs and text documents were scanned at various resolutions. Several of these maps are depicted herein, but dozens of other maps and logs are archived at and available from the ISGS. These data will be made available to researchers on request. Because of the sheer volume of material scanned, the data are still being organized. We hope that it will be made available online, but at present, the size of the digital data set is more than 500 gigabytes. Although the data have been collected, additional money is being sought to properly organize it and make it widely available.
