SnapshotLogan consists of four active underground mines (Powellton No. 1, Lower War Eagle, Eagle No. 1 and Muddy Bridge) and supporting infrastructure that produce High-Volatile Met coal and one active surface mine (Toney Fork) and supporting infrastructure that produce both Met and thermal coal. The Logan complex life plan includes 12 proposed mines, consisting of nine underground mines and three surface mines.

Logan produces primarily High-Vol Met coal (HVA HCC and HVB HCC), mined from various seams of the Kanawha Formation, most of which are situated below drainage; however, several Met coal seams are situated above drainage. Logan also produces thermal coal from upper portions of the Kanawha Formation. The Property lies in the Central Appalachian Coal basin in the Appalachian Plateau physiographic province. The coal deposits in the eastern USA are the oldest and most extensively developed coal deposits in the country. The coal deposits on the Properties are Carboniferous in age, being of the Pennsylvanian system. Overall, these Carboniferous coals contain two-fifths of the USA’s bituminous coal deposits and extend over 1,448 kilometers from northern Alabama to Pennsylvania and are part of what is known as the Appalachian Basin. The Appalachian Basin is more than 402 kilometers wide and, in some portions, contains over 60 coal seams of varying economic significance. Seams of economic significance typically range between 0.3 meters and 1.8 meters in thickness, with relatively little structural deformation. Regional structure is typically characterized by gently dipping strata to the northwest at less than one percent. The coal-bearing formation of interest at Logan is the lower section of the Allegheny Formation and the Kanawha Formation, which comprise a major portion of the exposed ridges. The Formation are a coal bearing sequence of sandstones, siltstones, shales, and mudstones with minor occurrences of siderite, limestone and flint clay. Coronado mines several horizons within the Kanawha formation. The horizons are as follows: Buffalo Creek, Upper Clarion Rider, Clarion, Lower Clarion, Upper Stockton, Lower Stockton, Lower Coalburg, Lower Dorothy, Upper Winifrede, Lower Winifrede, Chilton-A, Chilton, Upper Cedar Grove, Middle Cedar Grove, Lower Cedar Grove, No. 2 Gas, Upper Powellton, Lower Powellton, Eagle, and Lower War Eagle seams demonstrate mining potential on this property. Logan currently has four active underground mines and one active surface mine. The Toney Fork mine is a surface mine, while the Powellton No. 1, Eagle No. 1, Muddy Bridge and Lower War Eagle are underground mines. The active Toney Fork surface mine has historically mined multiple seams including the Upper Winifrede, Lower Winifrede, Upper Clarion Rider, Upper Clarion, Lower Clarion, Lower Coalburg, Upper Coalburg, Upper Stockton, Lower Stockton, Chilton-A, and Lower Dorothy Seams. Future surface mine reserve production at Logan is anticipated to focus on those seams having the best opportunity for sale into the metallurgical coal markets, namely the Lower Coalburg seam and below. The Powellton No. 1 Mine is projected to extract the Lower and Upper Powellton jointly in some areas, while other areas are projected to extract only the Lower Powellton due to seam splitting. The Eagle No. 1 and Muddy Bridge Mines are projected to extract the No. 2 Gas seam. The Lower War Eagle mine is projected to extract the Lower War Eagle seam. The coal produced at Logan Mine complex is typically high-volatile (typically 28 percent or greater volatile matter content) bituminous coal. Quality varies with distance from the cropline, so some seams will be shipped into both the thermal and metallurgical markets depending on mining method and ultimate quality. Saleable product from the surface operations is projected to be sold primarily into the metallurgical coal market; however, some production is planned to be sold into the thermal coal market due to quality limitations. Underground coal is sold almost exclusively into the metallurgical markets. Logan’s reserves are one of the largest contiguous blocks of premium, high quality, low-cost High-Vol coal in North America. The thermoplastic (fluidity) properties of the coal produced at Logan make it well suited for coke making and its coal has a well established reputation for quality in both the domestic and export marketplaces.
