Black Canyon is conducting development and feasibility studies for an open pit development in Western Australia's Pilbara region, about 400m from Port Hedland.
It announced the results of a 1.8Mtpa scoping study in August, based on a 36Mt at 11.7% production target, defining a multi-decade mine life with a A$44 million development cost generating $2.3 billion in earnings.
Managing director Brendan Cummins said Flanagan Bore's deposits continued to show a high level of continuity, from outcrop down to about 40m below surface.
Earlier this week Black Canyon lodged a mining lease application, and hopes to be in a position to take a development decision by early 2024.
Studies are also ongoing to assess potential for production of high purity manganese sulphate.
