Q4I do know that beginning in Q2/ 2022 they have been removing overburden ( stripping ) the far bank of the open pit where the first mining bench is to be configured for mining.
If I remember correctly from the HKEX document, this would take about 6 months .
Its possible therefore that we might get a month or so of mining this Quarter.
In any event, mining will quickly ramp up in 2023.
