VANCOUVER, Feb. 8, 2012 /PRNewswire/ – Capstone Mining Corp. (“Capstone”) (TSX: CS) today announced the result of an updated National Instrument 43-101 compliant mineral resource estimate for the Mala Noche Footwall Zone (“MNFWZ”) at its Cozamin Mine in Zacatecas, Mexico. Follow-up drilling in the MNFWZ in the second half of 2011 has added an additional 28 million pounds of copper resource in the measured and indicated (“M&I”) categories. At a US$35 NSR copper cut-off grade (“COG”), total measured and indicated mineral resources at the Cozamin Mine at the end of 2011 was 419 million pounds of copper. A tabulation of total mineral resource by classification is appended at the end of this news release.

“With this increase in tonnage and contained copper, Capstone has mine planning and cost analysis studies underway directed toward converting much of the M&I class resource to mineral reserves,” said Brad Mercer, Vice President, Exploration for Capstone. “In addition, underground exploration drilling is continuing with two drills, for further infill drilling aimed at upgrading the classification of the more than three million tonnes of resource currently in the inferred class and to seek further expansion of the deposit by stepping out in both the down dip and eastward directions.”

Compared to the June 20, 2011 mineral resource estimate, at a US$35 NSR COG the grade of the M&I category decreased from 2.32% Cu to 2.10% Cu, but the tonnage increased by 766 thousand tonnes to 2,217 thousand tonnes and contained copper metal increased by 28 million pounds. These changes are largely attributed to an increase in drill hole density where infill drilling of areas that were previously inferred class have resulted in a reclassification to indicated.

This estimate also uses a revamped approach to sub-domain individual veins and a more robust geological interpretation that uses a percent block model that better constrains metal grades while increasing confidence in geological continuity suitable for mine planning and production development. The new estimate for the MNFWZ is tabulated below at a US$35 NSR COG and it is presented at various other NSR COG’s at the end of this news release to show sensitivity to changing cut-off grades. Test mining to date in the MNFWZ has been positive, with the extraction of 61.7 thousand tonnes of development ore from the MNFWZ at an average grade of 2.00% copper.

Subsequent to the mineral resource estimate reported herein an additional 26 holes have been drilled at the MNFWZ but assays are not yet available for inclusion in the resource estimate. Exploration drilling is ongoing at both the MNFWZ and the Mala Noche Main Vein and is anticipated to continue for the remainder of 2012 in a planned $6.5 million program (32,000 metres). The Company anticipates re-estimating the Footwall Zone mineral resource when a critical mass of new drill data is attained, expected towards the end of 2012.

Cozamin Mine – Mineral Resources by Class for the MNFWZ as at December 31, 2011 at a US$35 NSR COG*

* Metal Price assumptions (in USD) used to calculate the NSR COG for all deposits are: Cu=$2.50; Zn=$0.80; Ag=$20.00.
Processing recoveries used to calculate the NSR COG for the MNFWZ Resource are: Cu=92%; Zn=69%; Ag=72%

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. Even though test mining has been undertaken in areas of the MNFWZ with M&I class mineral resources there is no certainty that inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.

MNFWZ Mineral Resource Estimate Methodology

The mineral resource estimate for the MNFWZ reported herein was prepared by independent consultant Ali Shahkar P.Eng., Principal Consultant with Lions Gate Geological Consulting Inc. (LGGC) located in Sechelt, BC, Canada. The estimate was completed using GEMS^© software using a three dimensional block model (10 metre by 5 metre by 3 metre block size). The main structure that hosts the MNFWZ mineralization was interpreted as a three dimensional wireframe domain as was the case in previous models. This domain was treated as a general background within which three individual vein wireframes were interpreted and constructed as part of the new model for the MNFWZ. The three vein wireframes were used as hard boundaries to constrain the interpolation of grades into the block model. Interpolation parameters have been derived based on geostatistical analysis conducted on 1 metre composited drill hole data. Block grades have been estimated using Inverse Distance Squared (ID2) method and the mineral resources have been classified based on proximity to sample data and the continuity of mineralization in accordance with CIM best practices. The MNFWZ resource has been estimated using a total of 109 diamond drill holes, variably spaced at 50 to 150 metre intervals.

Analyses for copper, zinc, lead, silver and gold were completed by ALS Chemex using the following method. The entire sample is crushed to a minimum of 70% minus 10 mesh. A 250g subsample of the crushed material is then pulverized to 85% minus 200 mesh. Gold and silver grades are determined by gravimetric fire assay using a 50g charge taken from the pulverized material. Copper, zinc and lead are determined by ICP analysis after 4 acid digestion of a 0.4g subsample of the pulverized material. Blank, standard and duplicate samples are used for quality assurance and quality control.
