If Ian was a real smart guy he should lock in 50% of forecast production at $20.00 / pound for the next 20 years. That would be 6500 tonnes of the lower grade ore.
This would always guarantee production for the mine and Be a fail safe stop gap when the V price crashes in 10 years below $10 / pound. Allowing of only 50% of lower grade ore to be shutdown during slow times.
The high grade V will look after itself into specialised marketS just like in other markets and which Ian has previously outlined in interviews.
I think I might forward my opinion to him : )
