There was a strong reason all their efforts focused on the "high density cobalt zone".  2 years ago it was all about cobalt, nickel was always part of it, but cobalt is what drove this into start up mode, look at their early 2017 presentation "focus on cobalt"..  Cobalt is also what sent the shares flying high in 2017, and down in 2018.  

Its shifted a bit, as
1.  cobalt price reversed and
2. the shift to more nickel and less cobalt in the evolution of the lithium ion batteries.
3.  projections that class 1 nickel demand may grow even faster than cobalt demand 

But I still trend it towards cobalt, because cobalt is locked almost exclusively in the Congo, that Ardea has maybe the largest cobalt deposit outside of africa is what differentiates it. That they have a safe and ideal jurisdiction for cobalt is probably more strategically valuable to potential partners who are needing a reliable and ethical source of cobalt.  Nickel doesn't have those issues, but we have monster deposit of it, and it looks like nickel is extremely well positioned in this energy revolution, so yea, we got that going for us too.
