Ann: First Mixed Rare Earth Carbonate (MREC) Produced at Caldeira, page-46

I am new to HC and a shareholder of MEI and although a shareholder and wish the best for the company I was in the process of investing another 400-500k from the sale of a property as I love and believe the the rare earth space and was enquiring further to another post to the recent announcement, titled "First Mixed Rare Earth Carbonate (MREC) Produced at Caldeira". that stated within the announcement, a global recovery for total rare earth oxides (TREO) of 53% within Table 1. Given the mass of CDM composite used in the MREC production of 25 kg and assayed head grade of 4,439 ppm TREO, against the mass of MREC produced of "approximately 50 grams" at a TREO grade of 57.3 wt%, the actual global recovery for TREO in production of the MREC product appears to be 26%. The discrepancy is very large (around 50%) in that it may not be explained by sample loss within the testing due to assay samples of 2-10 g at each process step. Can you MEI please elaborate on how the global recovery of 53% for TREO to MREC that was stated in Table 1 was derived? and why I should further invest more money or sell me shares albeit at a loss.
