You don't crush the rock in micro-diamond extraction,...so if there are big ones, they will be found. Some known diamond controls are added to ensure the extraction and processing is working properly and the results have integrity,...ie)not destroying diamonds present.

Micro-Diamond Extraction By Caustic Fusion

Uncrushed rock, drill core and drill chip samples are mixed with chemicals, heated and dissolved in high temperature kilns. The lack of crushing is to avoid contamination and diamond breakage risks.


A series of chemical processes reduce samples to residues consisting of diamonds and a few other resistive minerals.

Any large diamonds are removed under strict security procedures. Samples weighing 10kg are commonly reduced to 0.2% of initial mass.
Samples are spiked with known diamonds to ensure quality.

Haven't heard from Brooke. He's at the mining show. We need to know what screen was used. As we all know, the core rock is crushed through a crusher to a predetermined size. From what I understand, and I can be wrong is progressive crushing was not conducted for the micro diamond testing. Of course, while observing, if they find bigger stones, they'll report it. From my discussions with a few, the emphasis is not to locate stones > 1mm during the diamond micro testing. Will find out more details and will promise to try and do a better job on how my view is explained. <gggg>

BTW, will p, valuepro, russett, vaughn, marcos, anyone else, have a recent report by a broker I use. The report is on the coronation diamond district. If interested in a copy, email me and will glady send it. The report has a table comparing core results from Lac de Gras in comparison to the Coronation pipes, Potentila, Artemisia, Anuri and Knife. This is better than me writing and confusing the issue. Sorry guys, At times, I can be a lousy writer when trying to explain the technical jargon.. I am a business geek not a techie geek.<ggg>
For the report, you can reach me at smallcap@hotmail.com.........frank
