       In June 2007, a fatal accident occurred at the Midas mine in
       Nevada, which resulted in a temporary suspension of operations
       at the mine to initiate rescue and subsequent recovery efforts.
       As a result, the Mine Safety and Health Administration
       (&amp;#8220;MSHA&amp;#8221;) issued an order requiring operations to
       temporarily cease at the mine. During the third and fourth
       quarters of 2007, activities were undertaken, at the direction
       of MSHA, to regain entry into the mine in order to resume
       commercial production which restarted in October 2007. The
       redevelopment and holding costs of $11 in 2007 included access
       development, inspection, preventative repairs and road and mill
       maintenance.
   &lt;/div&gt;
   &lt;/div&gt;
