Ramelius flags pit wall collapse

First blast of waste rock at the Mt Magnet gold project in September 2011.

Embattled gold miner Ramelius Resources has flagged more bad news with a pit wall collapse its Western Queen South mine.

The company has called a trading halt on its shares, pending an announcement about the wall failure.

Earlier this month, Ramelius announced an electric motor that drives the ball mill at the company's Mt Magnet processing plant had broken down and needed to be replaced.

It warned the break down would affect its production guidance for the December quarter because of reduced capacity.

Ramelius has also been hit by a sagging gold price.

Its shares last changed hands for 10.5 cents, not far from a 52-week low of 9.8 cents in June and a far cry from its year high of 56.5 cents in January before the price of gold plummeted.

Ramelius began mining at its Western Queen South project in March in a bid to boost production to 100,000 ounces a year.
