Dr. Robert Holt Department of Geology and Geological Engineering University of Mississippi Friday, September 13, 2019 - 3:35pm Geography/Geology Building, 200A Special Information: Contact Dr. Adam Milewski for more details. Colloquium Twin Pines Minerals is proposing to use a novel approach to mine heavy minerals along Trail Ridge in Charlton County, Georgia. Twin Pines will use mobile drag lines to excavate mineralized sands from a small mine pit (500 feet long, 100 feet wide, and 25 – 70 feet deep). After processing, 98% of the mined sand will then be returned to the inactive portion of the mine pit. The mine pit will advance approximately 100 feet per day. The inactive portion of the pit will be filled with spoil, at the same rate the pit advances, and reclaimed. Any portion of the pit will remain open approximately 5 days. The topography of the reclaimed mine spoils will be returned as close to pre-project elevations as possible, with the final elevations determined from recovered groundwater levels. The post-project wetland area will be equivalent to the pre-project wetland area, and upland areas will be constructed for Long-Leaf Pine.
