Capstone Reports Additional High Grade Copper-Gold Results at Minto North



    
    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.

"plans", "expects" or "does not expect", "is expected", "budget", "scheduled",
"estimates", "forecasts", "intends", "anticipates" or "does not anticipate",
or "believes", or variations of such words and phrases or statements that

cause the actual results, performance or achievements of the Company to be
materially different from any future results, performance or achievements
expressed or implied by the forward-looking statements. Such factors include,
among others, risks related to actual results of current exploration
activities; changes in project parameters as plans continue to be refined;
future prices of mineral resources; possible variations in ore reserves, grade
or recovery rates; accidents, labour disputes and other risks of the mining
industry; delays in obtaining governmental approvals or financing or in the
completion of development or construction activities; as well as those factors
detailed from time to time in the Company's interim and annual financial
statements and management's discussion and analysis of those statements, all
of which are filed and available for review on SEDAR at www.sedar.com.
Although the Company has attempted to identify important factors that could
cause actual actions, events or results to differ materially from those
described in forward-looking statements, there may be other factors that cause

those anticipated in such statements.
    Accordingly, readers should not place undue reliance on forward-looking
statements.
