VANCOUVER, Sept. 21 /CNW/ - Capstone Mining Corporation (CS: TSX) today announced assay results from the remaining twenty-five drillholes completed as part of 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, increase Capstone's confidence level in the previously announced mineral resource estimate. These results confirm the geological model that was the basis of the initial mineral resource estimate and provide infill data from holes drilled between prior holes, all of which should support a more robust classification of these resources. An updated mineral resource estimate for Minto North is in progress and will be incorporated into the Phase IV expansion study which is currently underway. Highlights of assays from these most recent drillholes are summarized in the table below and the full results for the twenty-five holes released today are provided in the attached table.

"The five holes highlighted above once again illustrate the high grade nature of the Minto North deposit," said Stephen Quin, President & COO of Capstone. "Of equal importance is the confirmation of continuity within the high grade core of the Minto North deposit and within the near surface, moderate grade and thick mineralized horizon in the eastern half of the deposit. Combined, this should result in a robust resource estimate that is largely in categories that may be included as reserves within the pre-feasibility study currently in process."

Minto North Deposit

Capstone previously announced a preliminary mineral resource estimate for Minto North on June 9, 2009. The aim of this subsequent infill drill program was to boost confidence in this estimate, sufficient to support a conversion to mineral reserves if economic factors warrant by demonstrating both continuity of grade and thicknesses. A new mineral resource estimate is in progress and will be incorporated into the Minto Phase IV expansion study.

Results for this final batch of 25 holes marks the successful conclusion of the infill program and brings to 86 the number of drillholes delineating this deposit, up from 31 which was the basis of the initial mineral resource estimate. With a 177% increase in the number of drill holes over the original model and using a drillhole spacing similar to that which supports the definition of measured & indicated mineral resources and mineral reserves elsewhere at the Minto Mine, Capstone believes it has the confidence level required for a conversion of these mineral resources to mineral reserves, should economic factors warrant.

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 Inspectorate America Corporation.
