US: USG has proposed to the Forest Service that it be allowed to conduct exploratory core drilling on National Forest System (NFS) lands south of its Shoals gypsum wallboard plant in Indiana. The drilling is intended to verify probable mineral resources within a 520ha area of NFS land ahead of future mining activities that would occur from the plant, according to the Washington Times-Herald newspaper. The USG drilling proposal is for a duration of two years beginning in the spring of 2023.
USG owns the subsurface mineral rights for mining gypsum deposits while the Forest Service owns the surface rights to a portion of land located within the Hoosier National Forest. The Forest Service previously gave permission for USG to conduct drilling on most of the land in 1995 but it is currently evaluating the impact it would entail, considering mitigation options and seeking public comment.
