Mineral Properties [Abstract]  
Impairment of mineral properties

We have determined that no impairment provision is currently required. A write-down in the carrying values of one or more of our mineral properties may be required in the future as a result of events and circumstances, such as our inability to obtain all the necessary permits, changes in the legal status of our mineral properties, government actions, the results of exploration activities and technical evaluations and changes in economic conditions, including the price of gold and other commodities or input prices.
