I'm not sure that "appetite" is quite the correct word for the situation. The Financial Crisis resulted in, among other things, banks in North American being virtially prohibited from putting money into mining, so one of the major sources of funding has been cut off.
Meanwhile, selected exploration and development projects continue, if not being involved in outright sales - Resolution Copper, Rosemont, Mission-Pima to name a few.
IMO, "If you build it (i.e. drill it), they will come", meaning results can trump market conditions. And this is what I expect for HMSP.
Besides, and in my opinion, the really big money I see being made here will come on those projects following Hay Mountain (assuming it is first to be drilled and "hits" as we suspect it will). Also, and if it "hits" as expected, it too could be bought out rather speedily by any large company hungery for rich ore that can be exploited speedily (and with infrastructure pretty much already available).
...and we could be in an entirely different, and hopefully better, market by the time we see drilling anyway.
No worries here, though I am growing callouses from drumming my fingers in impatience.
