The explorer said it was "extremely excited" by one of the holes in the maiden program that assayed 29m at 1010 parts per million lithium from 210m in "claystone", a headline result among a number that have "exceeded all expectation".
Pleasingly for the explorer, the claystone unit is believed to be flat lying, meaning the drill intercept "near true width".
FBM, which was previously a nickel explorer in Australia called Auroch, is led by Rob Cox.
