Ann: Drilling Delivers Further High Grade Lithium at Burmeister, page-49

It would however be good to see TG6 do a real world test of this. Take an area they know well, like 20m from an existing drill hole where a thinner good grade seam exists. Decide the expected sample range before drilling that includes Mafic at each end. If the DD sample drilled hits the planned pegmatite, quarter cut for starting assays but say 8 or 10mm crush the rest of the core (including mafic) and optical ore sort screen it. This would provide a good idea of the recoverable post crush ROM material would be from mining thinner seams. If the grade and recovery rate to that point is robust, thin seams are not a major issue. With many thinner seams a test like this is needed to provide the market confidence thinner seams are not a major issue in the context of TG6 ore.
