In that case, another African lithium explorer you appear to hold would likely have recently entered the orphan phase. As they look to have already proved a large resource and are yet to prove that it is feasible to mine (refer to area on graph immediately following discovery)
Comparing this to BGS, we already know it is feasible (refer to crappy PFS done with a tiny part of our likely resource, using costs that can be proved way over the top, in addition to the very conservative sale pricing model used, let's say around the development point of the graph). Yet BGS still has extremely large exploration potential (refer to this Ann and the discovery portion of your graph).
So in my opinion BGS is at both dips in the graph concurrently and should therefore be anticipating double the upside!
