Australian-listed Maryborough Sugar Factory aims to acquire smaller Queensland producers after a $A50m capital sourcing move. Major investor Guinness Peat Group (GPG) will participate fully, and is also setting up a separate transaction that will give Maryborough control over a stake of 19% in the Sugar Terminals operation. GPG, the vehicle of corporate raider Sir Ron Brierley, has taken advantage of the recent stock market turmoil to overhaul its portfolio of investments. It has sold its holding of 6% in ABB Grain, and is pursuing Gosford Quarry Holdings. Its cash stands at Stg239m ($A509m)
