Jim Kennedy''s $1 Billion Plan to Break a Chinese Monopoly

2022-7-12 · Piled up in Pea Ridge''s old tailings lake and buried underground are unusually high concentrations of so-called rare earth elements (REE). Geological studies indicate Kennedy''s property is home to some $3 billion worth of known "rare earths" reserves. What''s more, Pea Ridge is one of only two permitted REE mines in the country.
