Ann: Mineral Resources Shareholding in Essential Metals, page-104

There's additional context on the MIN statement for WGO - it was made while MIN had a concurrent takeover offer for NWE which was under pressure to be sweetened (and eventually was).

There's no benefit in this instance (that i can see at least) of MIN making its intentions public and limit its options by being bound under Truth in Takeovers to act accordingly. I'm not of the view that an opposite scenario to WGO can be inferred based on the lack of a formal statement
