Per rules, not editorializing the title. This news is about a month old, but curious on thoughts?

The following minerals were found at Pennington Mountain, which is just south of Eagle Lake in Aroostook county. This is in addition to the estimated $1.5B lithium deposit near Sunday River. It looks like Maine could have a future in extracting very valuable metals for important technologies. Current law prevents mining, however.
