Uh, yeah.  Can it wait until morning?  I'm going drinking.
But real quick:  Nickel isn't s precious metal (not that that matters, but thank you for letting me be an arrogant #####) it's an industry metal and unlike cobalt - which is a byproduct metal of nickel and zinc and 65% located in the DRC - nickel can be mined in several garden spots around the world like Indonesia or Malaysia or, again, the DRC.  
The other thing is leverage to nickel is tough to find - it's generally a metal that's a small fraction of a behemoth global metal miner so if it's 10% of what Glencore does and the price spikes, it isn't going to lift the company too much higher. 
The old Cobalt27 company is a nickel company now. They might even be changing their name to Nickel28.  But I trust their management team like I trust 
@Bob Sacamano, and 
@cosjobsto guard my liquor supply.  
more tomorrow.  You're on the right track.  You ask a great question.
