If you search edgar, their ZTEM is in one of their filings, 2016-ish.  I think it was their only ZTEM, and was done over Section / Area 16 SW of the town, about two miles, and according to "the diggings .com" they still hold the claim(s) which is logical, if they have ZTEM and liked the results.

To new user: I don't know the Bureacratic obstacles to flying a survey, someone told me there were a few thrown up by AZ Land dept. but NR 175 is explicit - they flew a 130 SQ Mi. area - much larger even than the area the company has referenced in the most recent claim announcements.
