A tenth of the world’s tailing dams have had stability issues

The news came on the same day Royal Bank of Canada downgraded Goldcorp’s stock to “sector perform” from “outperform,” citing concerns over the miner’s ability to continue paying its monthly dividend.

Together these giant gold operations produce more than 10 million ounces per year.

The 24-hour stoppage did not affect operations, according to the mine management.

It saw its rough diamond prices decrease by 3% in February and a further 3% at its May trading session, but the mienr expects market conditions to improve by the end of the year.

Production is expected to reach 110,000 barrels per day, bringing total production to 220,000 barrels per day.

They are calling the company's shareholders “not to pay the price of ignorance” when it comes to investing in the Solwara 1 deep sea copper, gold mining project in Papua New Guinea.

After a more-than-likely Greek debt default the focus "may soon move on to the far more serious issue of potential Greek exit from the euro-zone itself."

The miner continues to extract high-grade ore samples at its Amaruq deposit, near its Meadowbank asset, Nunavut's only fully operational gold mine.

Both saw their stock collapse not just on these news, but also amid concerns that they will have to pay more for insurance that covers environmental damage.
