Gold rally narrows Acacia Mining, Barrick Gold offer gap ahead of deadline

Ahead of Tuesday's deadline for Barrick Gold Corp to make a firm buyout bid for its Acacia Mining unit, a gold rally has eroded, but not eliminated, a discount and big Acacia shareholders say they still oppose the offer.

Barrick must either firm up its proposal to acquire the 36.1% of Acacia it does not own by June 18, or walk away for at least six months under British takeover law.
