I doubt Rob would deliberately waste valuable cash on a non core asset. He is probably drilling to fulfill EL commitments which possibly results in EL surrender. The $200K grant obviously made it worthwhile. WA resource regs pertinent to RDM are;

1. That at the end of year 6, you have to surrender 40% of an EL.
2. You can hold an EL for a maximum of 12yrs. (2 x 5yrs plus 1 x 2yrs).
3. If A ‘holding’ title for a mineral resource that has been identified but is not able to be further explored or mined then the above rules do not apply.

I compared the March 2021 quarterly and the latest quarterly and 9 of the 15 Nullarbor EL's held in March qtr 2020 have been surrendered. 6 remain of which Forrest is one!
