Ann: Battery Minerals 121 Conference presentation, page-3

Thinking out loud:

• bulk samples were sent to prospective customers
• they complete their own internal testwork so I am thinking this relates to customer qualification of product suitability ( a necessary step before signing offtakes )

From the July 17 Quarterly:

The Company is now moving to process its bulk sample through a facility in China. Once processed into concentrate, much of the flake concentrate will then be further processed to purified spherical graphite. On completion of this programme, the Company will have sufficient data to achieve a DFS level of confidence in spherical graphite production. The DFS will focus on the supply of purified uncoated spherical graphite for use as anode material in Lithium Ion Batteries (LiB).
