True but it is only required if you cross the 5% share ownership level. 46M shares out of 1.96B is only 2.34% hence you would only suspect it can be Chester Nominees which is where MW holds his shares through or JP Morgan Nominees on the buy side would have to make an announcement whilst(not withstanding that if it was MW he would still have to disclose his purchase in any case being a director) whilst on the sell side it really can only be one of MC companies that have sold out... Yandal Investments Pty Ltd or Australian Gold Resources Pty Ltd. Better way to get info will be to compare current top 20 shareholder listing and when a new listing is released to market, or you pay for it.
