 Twenty Seven Co Ltd ASX:TSC December quarter highlights feature the completion of a reverse circulation RC drilling campaign at the Rover Gold Project in WA, and the identification of strong copper, gold and tin mineralisation at the Trident Project in NSW. Solid progress was made during the December 2021 quarter at both our Rover and Trident projects, notwithstanding some minor delays due to drill rig mobilisation and COVID-19 access restrictions in NSW, TSC CEO Simon Phillips said.
