Ann: Talga 31 March 2015 Quarterly Report and Appendix 5B, page-5

Quarterly was informative and probably the best one I've read over the last couple of days!

From the article a good mention about TLG:

However, proponents of natural graphite-based graphene still point to the apparent cost advantage of using a mineral as a raw material.

Australia-listed Talga Resources Ltd, which began making graphene "by accident" from ore at its Vittangi graphite mining project in northern Sweden a little over a year ago, said that cost was not an issue for its mineral-based material.

Mark Thompson, Talga’s CEO, said that his company’s graphene is essentially a by-product of its graphite processing and already beats competitor materials such as zinc on price.

The company recently announced plans to build a graphene demonstration plant in central Germany that will use Vittangi ore – a strategy that Thompson refers to as "moving the mountain to the microscope" – and is in talks with a number of triallists and potential customers in sectors including metals and plastics for the adoption of its graphene.
