If/when they start making a profit the logical use of funds would be exploration drilling within the current resource to expand it. The resource they are mining is open in multiple directions including at depth, so expanding the JORC resource and confidence levels is the quickest way to boost value once they are mining profitably. Alongside that - expanding capacity - mine development, dewatering lower levels and opening multiple drives, mill throughput, expanding tailing capacity etc.
They're mining a huge mineral system that was previously mined for decades up to the mid seventies. The upside potential here is enormous if they can get things on an even keel.
