RE: An actual question pertaining to ZEN, not "nam this orebody is a huge breccia pipe. the company drilled very large stepouts last year and pulled ore out of several widely spaced areas of the pipe. when examined under the microscope samples from all the drilled regions were identical.
the pipe was created by a volcanic event, a hydrothermal deposit. this is special as flake deposits are mostly sedimentary and have not been cooked at volcanic temperatures.
graphite maps out perfectly with airborn EM so there is reason to believe that the whole pipe is full of vein/lump graphite that has had the impurities cooked out of it by mother nature.
the Sri Lankan vein/lump deposits have tiny veins and more impurties than ZEN's ore, and ZEN's veins are huge (measured in meters while Sri Lanka's are measured in centimeters).
here's a bit more info for you including pictures...
