"That is all progressing well at the moment."

Mr Sasse said once designs are finalised they will be closer to beginning construction.

"We hope to finalise the design to the point we can reach financial close towards end of this month or possibly early August," he said.

"We are out in market at the moment getting prices for some aspects so there is a bit of talk among happening with local contractors."

"Our current best estimate for the start of earthworks is September this year, with roughly a 12 month construction program."
