Please understand where the TSE enters the picture. They do not set any specific rules for companies to release assay results immediately. They do however insist that they must review all news releases and approve them before being published.

As long as a company keeps assay results totally confidential they could hold them back BUT eventually they will release them AND at that time the TSE could have some serious questions about why the delay.

The TSE is acting like a policeman here and providing there isn't anything setting off warning bells (like funny share trading during period) they don't get involved. General rule of thumb is that 'Material Information' has to be released in a timely manner and what that means does leave 'wiggle room'.
