Fluffy, your comment on the use of ZEN's flow through cash is not correct. I believe hoov was trying to make the case that the money raised via flow through shares must be used in exploration. A bulk sample qualifies, as I presume would any work required to obtain that bulk sample, such as roads and drilling platforms.
What doesn't qualify is the purification of the graphite and the production of graphene. That's not exploration, and any money spent on that is not elegible for the tax break. The purchaser of the flow through shares is usually in it almost exclusively for the tax break, so any use of the money that reduces that break would not be welcome.
