20,000 cubic metres per annum for two years from start of December 2018.

The offer document included this statement:

In the event of sufficient take up by shareholders in the offer the company expects to be in a position to complete the works necessary to complete the bulk sampling project and to commence full production at the Talisman mine, including exploration, legal work required to commence full operations upon completion of bulk sampling and project development studies.

I recall but cannot find another mention of having completed the application paperwork for full mining operations.

There is still regulatory risk:
