Bottom lineFrom only my perspective
1st option
this year of course nothing is sure I hope they sell it 4-6 US dollar , despite the fact they really took care of permitting.
2nd option
if they go permitting alone , sell 75% , if with partner them wait a year to see how it goes
3rd option
1+1+1 then I will put it aside 4 years and fortget it because history tells me this kind of deals are good. This option in my case is doable since I am the eldest .. 54 years old , my Brothers are younger than me .I guess it is ok .
P.S You like it it not , Diamond has so many points right They could have finished years ago
