TORONTO, Oct 7 (Reuters) - Toronto's main stock index closed lower but well off the day's lows on Thursday as half of the index's sectors rallied into positive territory, but gold-mining shares remained a drag due to weaker bullion prices.
The S&P/TSX composite index .GSPTSE shed 55.79 points, or 0.45 percent, to unofficially finish at 12,445.93. The materials group, home to gold miners, fell 1.6 percent and was the heaviest decliner of the four sectors in the red. Six of the index's 10 main groups finished higher.
