Work to cap sulfide tailings will prevent further spread of
contamination

     (San Francisco, Calif. -- 04/27/2006)  The U.S. Environmental
Protection Agency is conducting soil capping work at the Anaconda Mine
site to prevent contaminated dust from blowing offsite.

     Work began in early April to move clean soil from areas of the mine
to build a soil cap over a 100 acre area contaminated with sulfide
tailings.  This work is considered time critical to ensure contaminated
tailings do not spread further at the mine site or off the property.

     â??The sulfide tailings were considered an imminent and substantial
threat requiring immediate actionâ?? said Tom Dunkleman, the EPAâ??s
Superfund on-scene coordinator for the Pacific Southwest region.  â??Work
is proceeding smoothly and we are confident we will complete the cap on
schedule.â??

     Water trucks are run continuously to reduce dust during the work
and air monitors have been set up around the work area to ensure dust is
kept to a minimum.  In total, 8 basins within the 100 acre area will be
capped.

     The capping work consists of using bulldozers to push vat leach
tailings material from adjacent areas of the mine site onto the sulfides
tailings.  One excavator is being used to load three 35-ton dump trucks
with the cover material, which is placed over the sulfides tails and
spread by the bulldozers.

     A February action memo initiated by the EPAâ??s Superfund cleanup
manager, Jim Sickles, requested the EPAâ??s emergency response group
perform the work to eliminate the environmental and health threat from
the sulfide tailings area. The tailings work is the second phase of
response activity at the site.  In February the EPA removed 119 PCB
containing electrical transformers from the facility, disposing them at
the Clean Harbors hazardous waste facility in Coffeyville, Kans.

     To date, cost of the emergency clean up work is approximately
$600,000.

     Originally known at the Empire Nevada Mine, the site began
operation around1918.  In 1953, Anaconda Minerals Company acquired and
began operating the site.  In 1977, Atlantic Richfield Company acquired
Anaconda and assumed its operations.  In June 1978, Atlantic Richfield
terminated operations and in 1982, Atlantic Richfield sold its interests
in the private lands within the site to Don Tibbals, a local resident,
who subsequently sold his interests with the exception of the Weed
Heights community to Arimetco, Inc. the current owner.  Arimetco
operated a copper recovery operation from existing ore heaps within the
site from 1989 to November 1999.  Arimetco has terminated operations at
the site and is currently managed under the protection of the United
States Bankruptcy Court in Tucson, Ariz.
