Snapshot	The Knox Creek Complex consists of a preparation plant, a coal loading facility, and a refuse impoundment. The Complex produces mid- and high-volatile metallurgical coal and also processes coal purchased from other independent producers from time to time. In the fourth quarter of 2019, Ramaco acquired multiple permits from various affiliates of Omega Highwall Mining, LLC. These permits, located near the Knox Creek preparation plant and loadout infrastructure, provide access to two mining areas in Southwestern Virginia: a deep mine permit in the Jawbone seam and a surface mine permit in the Tiller seam, mined via surface and highwall methods. In August 2021, Ramaco began production at the Big Creek surface mine and added a highwall miner in the fourth quarter of 2021. The mine reached full production during 2023. Ramaco closed its Big Creek Jawbone mine during 2024, as it was nearing the end of its mine life and experiencing higher-cost production.

Deposit type

• Sedimentary

Summary:

The upper coal seams of interest within the Knox Creek Complex belong to the Norton Formation in Virginia of Early Pennsylvanian Age, which is stratigraphically equivalent to the Lower Kanawha and New River formations in southwestern West Virginia. The lower coal seams of interest belong to the Pocahontas Formation of the Pottsville Group (Lower Pennsylvanian). The depositional setting for these seams is complex and thought to be upper delta plain, with subsidence controlling the sedimentation rate. The Lower Pennsylvania (Pottsville) sedimentary strata of the coal-bearing rocks of the Pocahontas Formation rest uncomformably on the Mississippian Bluestone Formation of the Mauch Chunk Group.

The coal seams of interest within the Knox Creek Complex are in the Southwest Virginia Coal Field and the Southern Coal Field in West Virginia. These coal seams are known for very high calorific content (Btu/lb)and high through low-volatile metallurgical coal characteristics, with high fluidity, low ash content, and low sulfur content.

Big Creek Property
The primary coal seams of interest on the Big Creek Property, in descending order, are the Red Ash, Jawbone 1, and Tiller. No significant faults have been mapped on the property.

Knox Creek Property
The primary coal seams of interest on the Knox Creek Property, in descending stratigraphic order, are the Kennedy, Red Ash, Jawbone 3, and Jawbone 1. However, there are several other mineable seams that occur throughout the property.

Deposit Type
The Knox Creek Complex resource area is a relatively flat-lying, sedimentary deposit of Pennsylvanian Age. The 34 coal seams in the Pocahontas Formation and the overlying Norton Formation account for approximately 3,000 feet of geologic section.
