Ann: Outstanding Ionic Clay Recoveries for Caldeira (updated), page-2

Only thing I can see changed here is in JORC table 1 it now states
"
Meteoric notes it is customary in rare earth processing to conduct impurity removal post leaching by increasing the pH and performing selective precipitation with an alkali slurry. The diagnostic leach tests undertaken do not accurately quantify impurities such as Al, Fe, Th, U that may be present in the leach liquor. Impurity removal analysis will be undertaken on a larger master composite that can accurately quantify the impurities in the leach liquor.
"

So they needed to update the ann to confirm they can't calculate impurity extractions with these diagnostic tests, which is why they didn't share them? Very strange, it's rare to see companies sharing acid consumption rates or impurity extractions, not sure why MEI need to justify themselves here.
