For the benefit of all PIO holders, I just read this from an ILC news:
...Mr. Brooks replaces Mr. Wayne Spilsbury, who resigned as a director of ILC on February 13, 2017. Mr. Spilsbury is also a director of Australian Stock Exchange-listed Pioneer Resources Limited ("Pioneer")...
13 Feb was the day the price stop rising. Not sure if it means anything for Mavis.
Any expert comments?
