Conference Call 
BILLINGS, MT -- (Marketwired) -- 04/17/14 --   STILLWATER MINING
COMPANY (NYSE: SWC) (TSX: SWC.U) (the "Company") today reported first
quarter 2014 platinum group metals production from its Montana mines
and from its recycling activities.  
Production from Montana Mines 
Production of palladium and platinum from the Company's Montana mine
operations totaled 130,700 ounces in the first quarter of 2014, a
2.8% increase over the same period in 2013. The 18.8% increase in
East Boulder Mine production in this year's first quarter compared to
the first quarter of 2013 was driven by slightly higher realized ore
grades and higher tons mined. The 3.0% decline in ounces produced at
the Stillwater Mine reflected lower ore tons mined and increased
allocation of resources to development activities during the 2014
first quarter compared to the first quarter of 2013.

Recycling Activities 
During the first quarter of 2014, total volumes of palladium,
platinum and rhodium processed from recycled material totaled 101,500
ounces, a decrease of 34.2% compared to the same period in 2013. The
decrease in recycling volumes during the first quarter of 2014 was
primarily due to weather related issues. Recycling material
deliveries have increased subsequent to the end of the first quarter
as overall weather conditions have improved.
