Investors will be anxious to find out more on the takeover talks between South Africa's AngloGold and Ghana-based Ashanti Goldfields tomorrow.
AngloGold is trying to buy Ashanti for $1bn (?625m) in shares, a takeover that could make it the world's biggest gold producer. A deal would help Johannesburg-based AngloGold overtake world number one Newmont and give the combined company annual production of 7.6 million ounces.
Both sides have warned there is no guarantee that a deal would be struck and urged shareholders to exercise caution, however.
