First Quarter Production of 16.7 Million Pounds of Copper in Concentrates

VANCOUVER, April 26, 2011 - Capstone Mining Corp. (TSX: CS) today announced its operating results for
the three months ended March 31, 2011 from its two operating mines, Cozamin
and Minto. Combined production totalled 16.7 million pounds of copper in
concentrates, with additional by-products of lead, zinc, silver and gold.

    - Cozamin                8.6
    - Minto                  8.1
    Total                   16.7

Operational Highlights for the three months ended March 31, 2011

The following is a summary of operational highlights for Capstone during
the first three months of 2011:

- Production of 16.7 million pounds of copper contained in concentrates.

- By-product production of 4.2 million pounds of zinc, 0.8 million pounds
of lead and 367,704 ounces of silver in concentrates. Final gold production
is not available since assaying is done off site, but is estimated at 2,925
ounces for the quarter.

- At Cozamin, remediation activities in the mine curtailed mining rates
throughout the first quarter. By mid-March most of these activities were
completed and mining commenced in the Avoca area at the end of March, which
is expected to contribute to higher productivity and grades throughout the
remainder of the year.

- At Minto, production was at low levels in the first quarter due to a
combination of lower mill throughput and lower grades.

- The lower grades at Minto were due to a high grade ore shortfall in
Stage 4 of the Main Pit, resulting in processing less high grade material
than planned. While insignificant in overall volume of ore in the Main Pit,
the decrease in grade negatively impacted metal production for the quarter.
Mining during the first quarter was focused on mining the final stage of the
Minto Main Pit (Stage 5) before freshet where ore grades have been consistent
with plan. Mining of the Main Pit is now substantially completed.

- Steady improvements to SAG mill throughput were made through the first
quarter. To assist with increasing throughput, additional crushing capacity
has been implemented through contract crushing, which began in mid-April to
remedy the throughput shortfall until design crushing changes are
implemented, expected late in the third quarter of 2011.

- Minto received the amended water use license in late March. Once
implemented, the revised license is expected to facilitate improved water
management at Minto during freshet. Application for the subsequent water use
license amendment, which will permit tailing discharge into the mined out
Main Pit, will be submitted by mid-May.

- The environmental and socio-economic evaluation for the Phase IV
expansion was completed and a decision document was issued recommending that
the project proceed. A temporary amendment to the current Quartz Mining
License was issued in March which allows stripping to begin for Area 2 mining
and development of the underground portal.

- Pre-stripping has commenced in Area 2 at Minto following completion of
mining the remaining ore in the Main Pit. A new Quartz Mining License at
Minto is anticipated in the second quarter that will permit the long-term
development of Area 2.

    (1) Adjustments based on final settlements will be made in future


Despite low production for the first quarter, Capstone is maintaining
full year 2011 guidance of 80-85 million pounds of copper in concentrates. At
Cozamin, production is expected to ramp up quickly from first quarter levels
now that mining has recommenced in the Avoca area. At Minto, contract
crushing commenced on April 15, increasing throughput rates to a level that
is expected to allow production to proceed as planned for the remainder of
the year.

Q1 Financial Results Timing

Q1 financial results are expected to be reported in late May or early
June 2011 and will be announced with conference call details once scheduled.
