The hiring of a metallurgist, with the intent of improving the baseline flow sheet.

"2. to further define the most efficient process flow sheet for the recovery of high purity product during the pre-feasibility stage."

And what has me puzzled is how a metallurgist who has worked with most metals, but not graphite, can improve on SGS' efforts, what with their being a graphite specialist having spent so much time working with ZEN's material. A material which is truly unique in its formation. They're bringing in a new guy who basically has to start learning about the chemistry of ZEN's graphite from scratch.
