Ann: Quarterly Activities Report and Cashflow - December 2018, page-7

aimzinc, Resgen's CFO had a mandate that is, for all intent, all but complete. He was meticulous and committed to getting all technical reports required for the approvals process, engrossed and updated accordingly.
Brendan's position moving forward will be filled by a person designated by the Board, at the relevant time. 
That person, without disrespect to the retiring CFO, will be appropriately qualified to undertake the role of CFO for Resgen, as a coal production company.
in the interim, Resgen has a number of suitably qualified practitioners in management who can fulfill the day to day role of CFO pending formal appointment of a replacement CFO.
