deposits at Minto and the Mala Noche Footwall Zone at Cozamin. In addition,
we look forward to advancing our third project, Kutcho, towards a production
decision in 2011."

Operating Highlights

- Cozamin, Mexico

- Produced 34.1 million pounds of payable copper at a total cash cost1 of
US$1.25 per pound.

- Updated the mineral reserve estimates for the Cozamin Mine,
incorporating a new mineral resource estimate, resulting in more than an
eight year life.

- Discovered and expanded the Mala Noche Footwall Zone ("MNFWZ"), located
in close proximity to the current mineral reserve and active mine haulage.
Exploration is continuing, with a new mineral resource estimate expected in
2011.

- Drove a cross-cut into the MNFWZ and lateral drifting was conducted on
one of several veins within the MNFWZ structure to determine strike
continuity and to conduct face and back mapping. The lateral drifting has 170
metres of advance at 4 metres wide and a 2% copper grade.

- Minto, Yukon

- Produced 38.9 million pounds of payable copper at a total cash cost1 of
US$1.53 per pound.

- Reported a 44% increase in the measured and indicated mineral resources
contained in the undeveloped deposits (excluding the "Main" deposit currently
being mined and the recently discovered Wildfire/Copper Keel and Inferno
deposits) based on drilling to the end of April 2010.

- Reported a first-time mineral resource estimate for the Minto East
discovery.

- Completed a Titan-24 survey over more than 85% of the property,
identifying 73 anomalies that warrant further exploration.

- Made two new discoveries, Wildfire and Inferno. These discoveries were
the result of testing a combination of Titan-24 geophysical anomalies and
geological models.

- The Phase V Prefeasibility study was substantially completed in 2010
and released in March 2011, extending the Minto mine life to 2020, at an
average annual production of 43.0 million pounds of copper in concentrates,
at a total cost per pound of payable copper of $1.34, net of by-product
credits.

- The Water Board hearing for the amended Water Use License was completed
in December. The amended license is anticipated before the end of the first
quarter of 2011.

- The Yukon Environmental and Socio-Economic Assessment Board evaluation
for the Phase IV Permit application was completed in 2010 and the Quartz
Mining License is expected by the end of the first quarter of 2011.

- Kutcho, British Columbia

- Issued an updated Preliminary Economic Assessment that significantly
enhanced the economic return of the project.

- Conducted a drilling and metallurgical program to advance the project
to a Prefeasibility Study.

- Mineral resource definition drilling within the Esso deposit
intersected some exceptionally high copper-zinc-silver-gold values.

- Issued a new NI 43-101 compliant Mineral Resource for the Esso deposit
in December 2010 with increases in resource classification and substantial
increases in metal grades.

- As reported February 24, 2011, completed a Preliminary Feasibility
study for Kutcho, providing a 12 year mine life, with an IRR of 27%, NPV of
C$155 million at a 10% discount rate and a 3.4 year payback after tax. A
technical report is expected to be filed on SEDAR by the end of March 2011.

Subsequent Event

- In January 2011, fully repaid the C$17.4 million owing to Yukon Energy
Corporation related to the spur and main power lines servicing the Minto
mine, 7 years ahead of schedule.

Outlook

Capstone forecasts that 2011 production will be 80 to 85 million pounds
of contained copper at a total cash cost per pound of payable copper of $1.30
to $1.35. Production is scheduled to ramp up over the four quarters of 2011
at the Minto Mine as crushing modifications are completed to increase
throughput. Full production from the Avoca stopes at the Cozamin Mine will be
delayed until late in the first quarter of 2011 as rehabilitation work is
completed as a result of the rock fall incident in late 2010, but is not
expected to impact annual production.
