so the funds used to invest in these equity investments were raised as a result of the CR to Lanstead I would have thought.

equity investment would not be related to commercialisation of proppants, not Graphene related, and not working capital.
Working capital for LWP would relate to w/c relating to the normal business of LWP. An investment in mining coys in Africa ain't part of LWP normal business activities.

relation to Resolution 6:
