STILLWATER MINING COMPANY SUSPENDS OPERATIONS AT THE EAST BOULDER MINE AS
                           DERBY WILDFIRE CONTINUES

    BILLINGS, Mont., Sept. 4 /PRNewswire-FirstCall/ -- STILLWATER MINING
COMPANY (NYSE: SWC)

    A precautionary evacuation order in Sweet Grass County associated with the
Derby wildfire has led Stillwater Mining Company management to suspend
operations at the Company's East Boulder Mine, located south of Big Timber,
Montana, beginning with the night shift on September 3rd.

    While there is no imminent threat to the East Boulder Mine, the safety of
the employees remains the Company's first priority.  Smoke and shifting winds
have created hazardous conditions in the general vicinity of the mine and
resulted in the evacuation order.

    Stillwater Mining Company management personnel will be in Columbus, Big
Timber and Billings to monitor the fire situation.

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

    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 South Africa and Russia.  The Company's shares are traded on the New York
Stock Exchange under the symbol SWC.  Information on Stillwater Mining can be
