Ann: OZL: OZ Minerals extends its Offer for Avanco, page-3

So 5 min before this ann is released the SP of OZL spikes in a flash from 10.02 to 10.12....lol

but this clause is interesting..

The current offer value represents a 132% premium to Avanco’s last traded
price before the Offer was announced on 27 March 2018. The current value has increased as OZ Minerals’
share price has increased over the period...
or EDIT...... has been made to ensure that it ihas increased....lol
