 STILLWATER MINING COMPANY ANTICIPATES REOPENING OF EAST BOULDER MINE ON FRIDAY

    BILLINGS, Mont., Sept. 7 /PRNewswire-FirstCall/ -- STILLWATER MINING
COMPANY (NYSE: SWC)

    Following consultation with emergency personnel, Stillwater Mining Company
announced today that the Company expects to resume operations at the East
Boulder Mine, located south of Big Timber, Montana, as early as Friday morning
if fire conditions remain stable. A small crew is scheduled to visit the site on
Thursday afternoon to complete advance preparations for the resumption of mining
activities. Full crews could then return to the mine beginning with the day
shift on Friday morning, contingent upon fire conditions and receiving clearance
from fire officials.

    An evacuation order in Sweet Grass County associated with the massive Derby
wildfire led the Company to suspend operations at the mine on the evening of
September 3rd. The fire has posed no imminent threat to the East Boulder Mine
itself, but smoke and shifting winds have created hazardous conditions along
access roads to the mine.

    Stillwater Mining Company employees who are scheduled to work can call (406)
932-8177 or (406) 322-8777 for updated work schedule information.

    As previously announced, the Company's Stillwater Mine resumed full
operations on Saturday, September 2, 2006, after its operations were suspended
for 2 1/2 days as a result of the same fire. All access restrictions reportedly
have now been lifted in the area of the Stillwater Mine.

    Stillwater Mining Company is the only U.S. producer of palladium and
platinum and is the largest primary producer of platinum group metals outside of
