Ann: March 2020 Quarterly Report, page-10

OGC mining at Didipio has been suspended pending renewal of its licence since the middle of last year as Jogo says.
OGC. 26/3/20. "Our strategy remains the same as it has been for the past year including the continued engagement with the Philippine national government for the resumption of operations at Didipio.”

Cash holding has been up and down like a yoyo recently. eg in Q2 it FELL $6.1 million.
Taking the 3 quarters of the current FY to date, Cash has increased from $23.4 million to $32.5 million, an increase of $9.1 million.
We don't know the current debt or net debt figure because MML don't disclose this metric in these reports.
Cash without reporting net cash is rather meaningless and should have been included in this reporting long ago.
In the Interim results to 31/12/2019 they disclose borrowings of $5.4 million. If we take that figure because the current figure is undisclosed then net cash is approx $$27.1 million.
