The Thunderbolts Project (EL 7184) is located 40km to the north-northeast of the Hillgrove mine or 95 km west of Coffs Harbour. The old Magword antimony mine is contained within this project. The vein/shear filling stibnite mineralisation was mined historically via underground shafts and adits with high antimony grades being achieved. Reports indicate that production between 1941-1969 was over 3,000t of antimony. An initial review of the exploration history indicates there has been very little exploration conducted in the area since 1972.
Other historic workings and deposits within the tenement area include the Allingham, Rock Abbey/Magdell, Abroi, Tregaire North, Sugarloaf and Antimony Gully antimony deposits, as well as the Faulkners gold deposit.
The Munga Project (EL 7185) is located 80km to the southeast of the Hillgrove mine or 75 km south-southwest of Coffs Harbour. The Munga Creek antimony district contains 23 known antimony deposits scattered along the length of the application area, most of which consist of historical workings. The Munga Creek deposit was mined in two phases between 1879-1884 and 1970-1974 and records suggest over 1,100 tonnes of antimony metal in concentrates was shipped from this mine.
