Ann: Change in substantial holding, page-49

Nothing new . Blackrock doing their usual thing. They did this when the SP was below 8c in the past and they buy and sell all the time. As Locust1 pointed out, it could be adjustments to their copper asset book and unlikely to be anything company specific. They will likely always keep a core holding as they have to protect their interests in the royalty scheme. They have no interest in seeing AVB fail (No more future royalties) and have a lot more interest in funding PB.
