Companies reporting:

Barrick Gold Corp. (TSX:ABX). Up 27 cents, or 1.65 per cent, to $16.62. The board of directors of Newmont Mining Corp. has unanimously rejected a hostile takeover offer from Barrick Gold and countered with a proposal of its own. The board says the unsolicited, all-stock US$18-billion proposal is not in the best interests of Newmont’s shareholders. Instead, Newmont, which is in the midst of acquiring Vancouver-based gold miner Goldcorp Inc., is proposing a joint venture with Barrick in Nevada where the companies both have extensive operations.
