Emmerson Resources Ltd (ASX:ERM) managing director Rob Bills is back in the studio after the company hit more high-grade copper-gold and cobalt-bismuth at the Tennant Creek Projects Hermitage prospect. Bills said the phase two drill program had exceeded expectations and that the cobalt and bismuth hits added to the inventory of future-facing metals relevant to the battery, superconductor, magnet and 3D printing suite of metals. Once the final assays are in, Emmerson plans to update its geological model, while further drilling is planned to test the extent of the high-grade mineralisation at Hermitage.
