    VANCOUVER, Aug. 10 /CNW/ - Capstone Mining Corporation (CS: TSX) today
announced assay results from 20 exploration drillholes recently completed at
"Minto North" at its high grade Minto copper-gold mine in the Yukon. These
most recent drill intercepts from Minto North, which is located approximately
600 metres north-northwest of the current open pit mining operation, are from
infill holes designed to better define the resource. These holes returned high
grade copper-gold intercepts, confirming the results of the initial discovery
and delineation drilling. Highlights of assays from these most recent
drillholes are summarized in the table below and the full results for all
twenty holes released today are provided in the attached table.

    "The results of the infill drilling at the Minto North discovery confirm
the high grade nature of this deposit," said Stephen Quin, President & COO of
Capstone. "Once we have the remaining results, we will complete an updated
resource estimate and include this significant addition in the expansion study
currently underway."
    A 56 hole, 6,575 metre program of infill drilling started on June 13 at
Minto North and was completed on August 5, 2009. With a drill hole spacing
similar to that used to support the definition of measured & indicated mineral
resources and mineral reserves elsewhere on the Minto property, this latest
drill program increases the amount of drilling at Minto North from 30 holes
and 4,371 metres used to define the preliminary mineral resource announced
June 9, 2009 to 86 holes and 10,946 metres, sufficient to support a
significant upgrade in the mineral resource classification. It is anticipated
that a large portion of the resource previously classified in the indicated
and inferred categories will now move into the measured and indicated
categories, a key step to facilitate a conversion from mineral resources to
mineral reserves, should economic factors dictate. These factors are currently
being determined by the Phase IV expansion study, which is recently commenced.
Included in the 86-hole total are two holes for an initial geotechnical
investigation of pit wall slope angles.

    Minto North Deposit

    The aim of this recently completed infill drill program at Minto North is
to boost the confidence in the preliminary mineral resource estimate
previously reported on June 9, 2009, 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 resource estimate. The 3D geological model is currently being
updated and a new estimation will start as soon as all assay data is received;
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 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.

among others, risks related to actual results of current exploration
activities; changes in project parameters as plans continue to be refined;
future prices of 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
