Ann: Half Yearly Report, page-42

OK makes sense. So to put it into hard numbers, you would say "good" met could be 50-60% NdPr extraction using pH 4 ammonium sulphate at 2600 ppm head grade (MEI & VMM) to maybe (if you buy the story) 70-80% NdPr extraction using pH 1 sulphuric acid (not hydrochloric) at 1800 ppm head grade but with cheap heap leach style processing (RDM).

IMO, and interested in any thoughts, 80-90% extraction using pH 0 hydrochloric at 1500-2000 ppm head grade (OD6 & MRD) is bad met based on how the market has sold them down to sub $5m market caps.

Keen to see what AR has cooking in the met lab. If they have even say 20% of the material in the MEI/VMM pH 4 basket they could be on to a monster.
