Hi Semi,
I am aware of all of WKT results from their Metallurgical samples, they have all been taken from the surface, it would also appear (according to the DFS) that WKT is following SYR's production method, we have seen how this has failed with the recovery of all of the course flake graphite.
"Following extensive metallurgical testwork of existing and new flowsheet applications for graphite, the Company has adopted a process flowsheet very similar to that used successfully in a previous graphite mining operation in Africa" Page 12 of DFS
The approximate 1m3 surface sample WKT provided to BGRIMM is not a true representation of the whole ore body,
Maybe you should read the content of your post above.

A large scale closed circuit test-work campaign was undertaken by the minerals processing laboratory BGRIMM. This is one of China’s key research facilities and has world leading expertise in graphite extraction. BGRIMM also has a manufacturing division that is the main supplier of attrition milling and froth flotation equipment to the Chinese Graphite Industry. Consequently, BGRIMM has unrivalled experience in laboratory testing and the specification of flowsheets & equipment for industrial scale graphite production. The sample selected for the BGRIMM testwork was high-grade surface ore (32% TGC), from the area where mining is planned to commence.
This sample was very similar to the Surface Composite Sample tested at Nagrom Laboratories in Perth in July 2016. After due allowance for fines recovery differences, the BGRIMM and Nagrom results were very similar.
