    Hole 09SWC508 intercepts 5.9% Cu & 2.6g/t Au over 16.8m (including 8.2%
    Cu & 2.9g/t Au over 10.2m)
    

VANCOUVER, Sept. 1 /CNW/ - Capstone Mining Corporation (CS: TSX) today announced assay results from eleven additional drillholes completed on the "Minto North" mineral resource infill drill program at its high grade Minto copper-gold mine in the Yukon. These most recent drill intercepts from the Minto North deposit, which is located 600 metres north-northwest of the current open pit mine, are from infill holes designed to better define the mineral resource and returned high grade copper-gold intercepts confirming the results of the initial discovery and delineation program. Highlights of assays from these most recent drillholes are summarized in the table below and the full results for the eleven holes released today are provided in the attached table.

"The infill drilling at Minto North continues to not only confirm the high grade nature of the Minto North deposit, but the four holes highlighted above demonstrate excellent continuity of the very high grade core up to the western margins of the deposit," said Stephen Quin, President & COO of Capstone. "Once all assay results are in, the mineral resource estimate will be updated and used in the Phase IV expansion study currently in process."

All Minto North drill core samples are now in the laboratory and results for the final 25 holes are expected shortly. With a drillhole spacing similar to that used to support the definition of measured & indicated mineral resources and mineral reserves elsewhere at the Minto Mine, this latest phase of drilling is sufficient to support a significant upgrade in the mineral resource classification and provide the confidence level required for a conversion to mineral reserves, should economic factors warrant it. These factors are currently being determined by the Phase IV expansion study, which is nearing completion.

Minto North Deposit

As previously reported on June 9, 2009, Capstone announced a preliminary mineral resource estimate at Minto North. The aim of this recently completed infill drill program is to boost the confidence in this mineral resource sufficient to support a conversion to mineral reserves by demonstrating both continuity of grade and thicknesses. Capstone believes this has now been achieved and has started the process to revise the mineral resource estimation. The 3D geological model is currently being updated and the new estimation will start as soon assay data for the entire infill program is received, which will be in time for inclusion into the Minto Phase IV expansion study.

Quality Assurance

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 and reviewed by Stephen P. Quin, P. Geo., President & COO for Capstone Mining Corporation. The exploration activities at the Minto project site are carried out under the supervision of Brad Mercer, P. Geol., V.P. Exploration (Canada) for Capstone.

The analytical method for the copper and silver analyses is aqua regia digestion of the samples followed by atomic absorption spectroscopy. Gold is analysed by fire assay fusion with atomic absorption spectroscopy finish for gold. Analyses are carried out by ALS CHEMEX in North Vancouver. When visible gold is noted in drill core samples or regular fire assay values appear abnormally high, the pulp and screen metallic assay method is used to determine the total gold content and gold contents of different size fractions. This is considered industry best practice when dealing with coarse gold mineralization where a nugget effect is suspected. This determination is accepted as the most representative value and is used in the assay database for mineral resource calculations. Blank and standard samples are used for quality assurance and quality control. Where more than two check samples assay outside expected ranges, the entire batch is re-assayed. After the completion of planned drill programs at Minto, random check assays will be carried out by Acme Analytical of Vancouver.
