Rare Element Reports Encouraging Rare-Earths Metallurgical Test Results
Metallurgical testwork is continuing at Mountain State Research Development International of
The three holes that provided samples for compositing and the testing were drilled to provide representative samples across the full width of the Bull Hill Southwest deposit, where an NI 43-101-compliant inferred resource has been estimated at 9.8 million tons averaging 4.07% rare-earth oxide (REO) using a 1.5% REO cutoff grade. The REE mineralization encountered in the three drill holes is primarily near-surface oxidized equivalents (“FMR”) of carbonatite dikes that intrude a body of heterolithic intrusive breccia forming the Bull Hill area of the Bear Lodge alkaline-igneous complex. The oxide zone of mineralization extends from surface to depths of 300 to 500 feet, and consists of a resource of 4.5 million tons averaging 4.3% REO. Excellent exploration potential provides encouragement that the oxide zone can be expanded considerably by step-out drilling.
“We are delighted with the results of our initial metallurgical testing of the oxide material, and plan to continue to work toward a feasible method of concentrating the rare-earth-bearing minerals and recovering the rare earth metals,” states President
Rare-earth assay values are reported by convention as the combined oxide equivalents (REO) of the fifteen elements in the lanthanide series. The oxide equivalents are approximately 15.6% higher than the combined metal assay values. The Bear Lodge project contains primarily the “light” REE (lanthanum, cerium, praseodymium, neodymium, and samarium, but also with minor europium, gadolinium, and yttrium).
