Ann: Change of Director's Interest Notice - Philip Crutchfield, page-24

My understanding is that board members cannot make stock transactions within a period of 2 weeks prior to a price sensitive announcement being made.

How that's known to administration though exactly - that an announcement worthy piece of information will be available is unknown to me, as a company cannot withhold information that is made available to them.

Surely given how busy labs are atm they cannot even forecast how far off assay results will be granted, or what if some surprising drill cores were pulled out of the ground that show distinct visuals before even requiring lab testing for percentages?
