Well the MEI cut off was 1000ppm and RDM hits are mostly 1700ppm + with one over 4000ppm by the look of it. Anyway mei is ionic clay and that original mre was based on only 10m deep drills holes I think (drilling deeper now) whilst RDM albeit in granite has 120m hits to end of hole from surface
Link to an interview - deposit some type of hybrid between hard rock and clay so not sure what the economics are.
Clay ionics I think can be ecominc as low as 500ppm for low grade, 1000ppm average grade and over 2000ppm for high grade. Hard rock usually over 1% or 10000ppm is decent or over 2% or 20000ppm for high grade.
So where does rdm sit in terms of grades it needs being a hybrid?
