The board has a plan of succession.  It must be in board minutes someplace, though I'm not sure it has to be public.  Having said that, there is no reason they should not tell you about it, it you ask.

JB has made clear his intentions regarding the future of the company, including some of his plans for expanding upon Tombstone area claims.  He made these things clear the few times I've been in his company, so board members must have significanly more details on these matters than I do.

While it may be shocking for some to contemplate the loss of JB at such a relatively young age - I'm right here with him -, I think the remainder of the BOD would rally, find another master of exploration geology, and set him on the paths already mapped out by JB himself, or they would not be board members.

...and I would look upon any knee-jerk selling based on JB's health to be a buying opportuntiy. 

BTW, I've always followed a guideline I learned long ago.  That is, if you begin to feel doubt, or a need to complain, it's time to sell and move on.  Few people ever get whole by complaining, or holding on in some vain attempt to at least break even.  Better to redeploy those funds into something that looks better..., if you are tempted to complain. 

Buying stock in exploration-phase mining companies ain't kid stuff, it's seriously dangerous, especially for those lacking an appropriate background.
