Sure .. 18 years ago you could have logged into the W.Australian mineral intelligence company Interria and seen such data - that business was sold to Standard & Poor and portaled there (and updated) for 14 years or so - recently it's no longer visible .. but such several such databases do exist .. I guess you just need the contacts and an account for access.

You can ask S&P, Rio Tinto and other majors, the Colorado School of Mines, US Military, the Chinese companies that were leaching data all those decades, ROSATOM (Russian Uranium) peers that track other minerals, etc.
