You might be able to answer the below, otherwise I have also emailed MEI for clarification. @setfire2thehive also interested in anywhere I have gone wrong below.

I was wondering why they used weighted averages for calculation the leach extraction in the Table 4, as it would have been better to just share the actual calculated leach extraction for leaching the 25 kg composite at larger scale and more realistic leach conditions (no pulverising the feed sample, higher % solids, larger tank). There appears to be a big discrepancy between their estimated global recovery and what was actually achieved. I make no claim that the below is correct, as above I am clarifying with MEI.



All the above sourced from the announcement itself. MREO grade above is the weighted average of the samples that went into the composite, they only shared the actual assay grade of the composite for TREO.
