"Would we want this information to be released if it's all negative?"

That depends on what they were looking for with their ultraviolet lamps.  That is why I've asked what possible economic benefit a UV survey of Hay Mountain would be to us (if anyone knows)?

I do know that chalcedony, among other examples, is a mineral capable of fluorescing under UV.  It is used for making industrial filters, mostly for water.  Nice collector specimens can fetch 5-10 dollars each*, but that's not nearly the type of income as could come from a copper mine.

Again, I have to ask, what were they looking for with a UV survey, diamonds?  Those are not likely to be in Arizona, certainly not in commercial quantities outside of women's fingers and jewelry stores. 

So, without other information, I would guess that a UV study over Hay Mountain will not produce anything of interest to us.  Having said that, I am eager to be informed otherwise.

*  I have many samples of chalcedony that I've collected from sites around Arizona.  Some places are richer in it than others.  I even have the articles of incorporation for one such project that failed to enter production some decades ago.  Nice pieces are still easily to be found there (and scorpions) but the site is now part of a nature preserve so nothing more can be removed.
