Ann: Vittangi Trial Mining Update, page-6

Well i agree that from a technical analysis point of view $0.70 is possibly the first stop.

However, if you look at it from a fundamental point of view, try this formula, using your own assumptions on % graphene & price graphene.
A major assumption is that the graphITE produced & sold covers all mining & processing costs, leaving the graphENE as profit!
Profit / Share = (Tonnes mined X % graphene X price graphene in $) / No shares of TLG on issue

Now on the trial mining of 2,000 tons this doesn't give VERY exciting figures, however on full scale mining of 50,000 tons! Phew!
Assuming they can find markets for all graphene produced.
