TORONTO, July 6 (Reuters) - Canada's main stock index fell on Thursday in a broad retreat, hurt by a slump in Tahoe Resources Inc THO.TO after its flagship silver mine's license to operate was suspended by a Guatemalan court reviewing claims that its awarding violated indigenous people's rights.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed down 75.24 points, or 0.50 percent, at 15,077.88. Nine of its 10 main sectors ended in the red, with Tahoe's value cut by a third.
