"any material information, such as drilling success, needs to be disclosed to market and appropriate valuations conducted."

This potentially gets a bit more interesting now.
Before, MIN had some control over when they passed information to NWE, especially with preliminary results.
MIN could legitimately argue that some information they had was not material to MIN due to their market cap.
This information may have been material to NWE due to their lower MC.

Now, with MIN having control and stating they would replace the BOD there can be a strong argument that they need to pass information to NWE on a timelier basis, due to a conflict of interest.

Not saying they have to pass all info on, but I feel they will have to be a bit more careful about not passing information on to NWE in the future.
