Capstone Announces Increased Mineral Resources Estimates for the Cozamin
Copper Mine, Mexico

10.7 million tonnes Measured and Indicated Resources at a Copper Grade of 1.6% Plus By-products

VANCOUVER, March 2 /CNW/ - Capstone Mining Corp. (CS: TSX) today announced an updated NI43-101 compliant mineral resource estimate for its Cozamin Mine in Zacatecas State, Mexico. The new mineral resource estimate includes the results from 6,229 channel samples taken in 2009 from 40 stopes and drifts covering a cumulative distance of about 5km, as well as more detailed survey control. These data were incorporated into a completely new block model for the mine that now contains 25,168 individual channel samples, 150 drill holes from surface and 216 underground drill holes. These new mineral resource estimates will be used in a new mineral reserve estimate for the Cozamin Mine, which is expected to be completed in March.

Capstone commenced mining the San Roberto deposit at the Cozamin Mine in 2006. Since commercial production began, 2.6 million tonnes have been mined at an average grade of 1.54% copper, 0.50% lead, 1.29% zinc and 71g/t silver. In addition to San Roberto, production from the adjacent San Rafael deposit commenced in late 2009. Robert Sim, P.Geo., of Sim Geological Inc., supervised the preparation of the updated mineral resource estimates for the San Roberto and San Rafael deposits. Summaries of these estimates are presented below, while additional details are attached.

"This updated mineral resource estimate demonstrates the robustness of the Cozamin mineralizing system," said Stephen P. Quin, President & COO of Capstone Mining. "Despite reductions due to mining activities in 2009, total contained copper and silver has increased modestly, while contained lead, zinc and gold have increased significantly. These gains are primarily the result of conversion of mineralized material previously below cut-off as a result of higher prices for lead and zinc" he said.

"Following the 2009 acquisition of three mineral claims in the immediate vicinity of these mineral resources, we are optimistic that we will continue to more than replace the production in the immediate mine area," said Mr. Quin. "Further, we have almost completed a sustained 12-month property wide assessment of the Cozamin Mine property, involving airborne and ground geophysics, soil and rock sampling and geologic mapping. This work confirms that there is significant potential for discoveries of new deposits along the principal Mala Noche vein that hosts all the currently known mineral resources, as well as in parallel vein systems." Capstone plans to begin the drill testing of the priority new targets by mid-2010.

Preparation of Mineral Resource Estimates

The mineral resource estimates for the Cozamin deposits were completed by Capstone staff under the supervision of independent consultant Robert Sim, P.Geo., of SIM Geological Inc., using accepted, industry standard, methods that conform with National Instrument 43-101. The resource model has been developed using MineSight(R) (v4.61).

There have been no diamond drill holes completed on either the San Roberto or San Rafael deposits in 2009. However, extensive underground channel sample data has been incorporated into the new mineral resource estimates, and the underground workings have been extensively resurveyed to provide greater accuracy to the data. Underground mining activities have occurred at both deposits during 2009 and this development continues to display a high degree of consistency and continuity to the mineralization.

Resource Estimation Methodology

The data and methodology utilized for the resource estimate is as follows:

    
    -   The resource model has been generated from a database containing a
        total of 366 diamond drill (core) holes collared from surface as well
        as from a series of underground drill stations developed on the No. 8
        level of the San Roberto mine workings. Drill holes have been
        oriented to intersect the mineralized zone at an average of 50m
        intervals in the majority of the San Rafael and San Roberto areas.
        Below an elevation of 1,900m (550m below surface), the drill hole
        spacing at San Roberto increases to an average of 200m. All drilling
        has been conducted from the hangingwall side of the deposit with
        pierce angle ranging from 45 to 90 degrees in relation to the plane
        of the mineralization. In addition to the drill hole data, there are
        a series of 3,811 chip-channels taken at approximately 4m intervals
        across the strike of the deposit in all development drifts in the San
        Roberto mine area. Approximately 250m of underground (mineralized
        zone) development was completed at San Rafael during 2009 but channel
        sample assay results were not available for use in the Dec 31 2009
        resource model.
    -   Drill hole samples have been analyzed for copper, zinc, lead, silver
        and gold at ALSChemex and SGS labs. Underground channel samples were
        analyzed at SGS early in the mine life and, more recently, at the
        Cozamin on site lab. All sample results are monitored with an
        appropriate QAQC program. Bulk density measurements have been
        conducted by site personnel on samples from 135 drill holes evenly
        spaced throughout the model area.
    -   The structural zone which hosts the mineralization at the Cozamin
        deposit has been interpreted using a combination of geology
        information and sample grade results in the drilling and channel
        data. This "mineral domain" strikes east-west for a distance of more
        than 3km, dips on average at -60º to the north and extends from
        surface to a depth -900m. The thickness of the mineral domain ranges
        from several metres to over 20m, with an average thickness of about
        7m (true).
    -   Sample data has been composited to 1m standard intervals prior to
        block grade estimations. The presence of potential outlier sample
        data has been evaluated and appropriate thresholds have been applied
        for all elements in both the San Rafael and San Roberto areas.
    -   Nominal block sizes measuring 5m by 3m by 3m at San Roberto and 10m
        by 3m by 3m at San Rafael, with the long axis oriented parallel to
        the east-west strike of the zone, are considered appropriate with
        respect to the sample spacing and the scale of the deposits.
    -   Estimates for copper, zinc, lead, silver and gold are made in the
        block models using ordinary kriging. Estimates for bulk density are
        made using the inverse distance interpolation method. Block grade
        estimates have been validated using several methods including
        extensive visual review with respect to the underlying data and
        comparisons with results produced using other interpolation methods.
    -   Mineral resources have been classified in accordance with the CIM
        definition standards for mineral resources and mineral reserves. The
        classification parameters are defined in relation to the distance to
        sample data and are intended to encompass zones of reasonably
        continuous mineralization.
    

Quality Assurance/Quality Control

Robert Sim P.Geo., of SIM Geological Inc., supervised the preparation of the mineral resource estimate for the Cozamin deposit. Mr. Sim has reviewed pertinent geological information in sufficient detail to support the data incorporated in the resource estimate. Robert Sim P.Geo., an Independent Qualified Person as defined under National Instrument 43-101, is responsible for the resource estimate presented in this release.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated mineral resource categories through further drilling, or into mineral reserves once economic considerations are applied.

The TSX does not accept any responsibility for the adequacy or accuracy of this press release.

Forward-Looking Information

This document may contain "forward-looking information" within the meaning of Canadian securities legislation and "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 (collectively, "forward-looking statements").
