VANCOUVER, April 25, 2011 - Capstone Mining Corp. (TSX: CS) today announced that its Cozamin copper
mine located in Zacatecas, Mexico has been awarded the Clean Industry
Certification from Mexico's Federal Attorney for Environmental Protection
(Procuraduria Federal de Protection al Ambiente or PROFEPA). This

"This important achievement represents the culmination of a 24 month
process of standards and management system documentation and implementation
by the Cozamin mine site," said Darren Pylot, Capstone's President and CEO.
"We congratulate our Cozamin operating team on attaining this certification,
which places Capstone in a relatively limited group of mining companies in
Mexico that have made the voluntary commitment to the highest standards of
environmental stewardship."

The presentation of the certification was made to Cozamin mine employees
at a ceremony at Cozamin by state and local authorities from the Secretary
of Labour, the Secretariat of Environment and Natural Resources
(Secretaria del Medio Ambiente y Recursos Naturales or SEMARNAT),
Municipality of Morelos, National Water Agency, Mexican Red Cross, Ejido
Hacienda Nueva, State Government and PROFEPA.
