throughout the region, along with valuable gold-bearing veins. Molybdenum mineralization also <br /> occurs in significant quantities, contributing to the area's mineral wealth. <br /> The modern landscape has been shaped by multiple geological processes over millions of years. <br /> Quaternary glaciation carved distinctive U-shaped valleys across the terrain, while fluvial <br /> processes from the Arkansas River system continued to modify the topography. The entire region <br /> was significantly affected by tectonic uplift during the Laramide Orogeny, which helped create the <br /> dramatic topography visible today. <br /> 1 . General Mining Plan — Mining Environments <br /> Excavation of prelaw waste will take place across the Mosquito Gulch area. This area, generally, <br /> consists of four identified Mining Environments. Prior to any mining activity, the mining environment of a <br /> waste pile will be identified based on the descriptions below, to guide mining and successful <br /> reclamation. <br /> No structures will be built as part of mining. All work will be accomplished by mobile equipment such as <br /> dozers, front-end loaders, track hoes, and haul trucks. <br /> 1 .1. Vegetated Loose Ground <br /> Heavily and moderately vegetated ground with either forest or shrubs on talus, landslides, glacial till, <br /> alluvium, or other similar non-bedrock geology. Topsoil is found on areas of this environment, with the <br /> exception of talus fields that have trees growing directly out of them. This environment includes <br /> solifluction deposits that are well-vegetated. <br /> 1.2. Non-Vegetated Loose Ground <br /> Areas of non-bedrock geology consisting of alluvium, talus, glacial till, landslides, or similar deposits <br /> that lack consistent vegetation. Topsoil is not typically found in these areas. <br /> 1.3. Vegetated Competent Ground <br /> Heavily and moderately vegetated ground that consists of topsoil directly atop hard bedrock. Loose <br /> non-soil rock is not expected in this environment. Topsoil may be thin but is present in some quantity. <br /> 1 .4. Non-Vegetated Competent Ground <br /> Little to no vegetation growing on areas of exposed bedrock. No topsoil expected in this environment. <br /> 1 .5. Mining Plans for All Environments <br /> For all of the mining environment a minimum mining plan will be followed. It is detailed below. Map C- <br /> 2A outlines a standard detail showing the configuration of mining at a typical waste pile. <br /> 1.5.1. Pile Quantification & Qualification <br /> The extents of each pile will be determined prior to excavation. <br /> 1) Determine pile volume, horizontal footprint, and underlying natural grade. <br /> London Mountain Clean Up <br /> April 2025 D-2 Lewicki&Associates <br />
