I guess a 40 year veteran is a pumper too.

"Overall leach extraction ofheavy rare earths (terbium, dysprosium, erbium, holmium, thulium,ytterbium and lutetium) plus yttrium, in all leach tests averaged 64%." https://www.pelemountain.com/pdfs/Table2_RareEarthExtraction.pdf
Withregard to REE recovery, Dr. Bird stated, "This means that up to64-percent of these valuable heavy REE, which occur with the uranium atEco Ridge, are available in the uranium leach solutions, at no extramining or milling costs. Chemical extraction of the REE from the uraniumleach solutions at Elliot Lake has been commercially successful in thepast. Pele is assessing extraction and recovery opportunities for REEby-products, along with an assessment of their potential contributiontoward project economics for inclusion in future Eco Ridge Mine economicmodeling purposes."
Shame he is willing to risk his reputation pumping GEM.
