The University of Arizona reports that "the Mineral Museum will continue to be open to the public due to the generous financial assistance of the Freeport-McMoRan Foundation and an anonymous donor."
I was surprised to read that "the UA Mineral Museum is the longest continuously-curated mineral museum west of the Mississippi. Officially recognized in 1919, the museum is now considered one of the top five collections in the United States and contains more than 27,000 minerals and 1,000 artifacts, including mineral specimens that date back to 1892."
