07-10-2020According to geologists, rare earths are not rare, but they are precious. The answer to what appears to be a riddle lies in accessibility. Comprising 17 elements that are used extensively in both consumer electronics and national defense equipment, rare earth elements (REEs) were first discovered and put into use in the United States.

25-08-2020Today, the United States is import-reliant on 31 of 35 critical minerals. And China now supplies the United States with about 80 percent of one important category of those minerals, known as rare earth elements. This was not always the case. In the past, we were able to produce the bulk of critical minerals the United States needed here at home.

08-11-2022Establishing the rare earth source materials program would require about four years of rulemaking and other preparations, according to DEQ, at an annual cost of $460,000. That money would come from the state's general fund. The ongoing expense of managing the program, including additional staff at DEQ, would cost an estimated $555,000 annually.
