A few other observation before signing off for lunch,

Below is a quote from the link you provided.

"The following significant observations were made: Flake sizes of coarse, medium and fine ranging from 50 to greater than 300 microns (-270 to +40 mesh size); Characterized as a magmatic hydrothermal style of graphite mineralization (similar to the high value Sri Lankan type deposits)

Graphite represents essentially all of the total reported Carbon assay values (i.e. Carbon related to carbonate is less than 1%)

Aubrey Eveleigh, President and CEO stated “Zenyatta management considers these latest results to be very important, especially the range in flake size, which includes the high value coarse flake. Coarse flake graphite is greater than 175 microns (or +80 mesh) in size. Flake size and purity are key parameters in..."

The company seems to pay attention to flake size and quality.

- to get top dollars, the deposit should have a large proportion in the large to jumbo flakes (NGC has a large % of jumbos). ZEN (cute name) gave the range of flake sizes, but not the size distribution...you might want to check this out. Also, I believe they call "large" flakes "coarse" flakes. NGC Corporate Presentation has a slide showing the price versus flake size.

- quality: Carbon contents have to be larger than 94% to be of economic value. If not, they would have to be upgraded/refined (at cost of course).
