Capstone Reports 44% Increase in Copper Contained in Undeveloped M&I Mineral Resources at Minto
By Capstone Mining Corp., PRNESunday, August 29, 2010
Interim Update Adds 252 Million Pounds of Copper Outside of Main Deposit; Exploration Continues With Three Drills
VANCOUVER, August 30, 2010 - Capstone Mining Corp. (CS: TSX) today announced the results of National
Instrument 43-101 compliant mineral resource estimates for four separate
undeveloped deposits at its high grade Minto copper-gold mine in Yukon,
Canada. New mineral resource estimates have been completed for all deposits
not currently being mined, including the Area 2/118 deposit, the Ridgetop
deposit, the Minto North deposit and the Minto East deposit. These are
interim results as the estimates only include drilling conducted to the end
of April 2010. Exploration continues with three drill rigs and additional
resource updates are anticipated in time for inclusion into an updated
pre-feasibility study currently underway. The updated mineral resource
estimates reported herein are for undeveloped deposits only and exclude the
Main deposit, which is currently being mined and processed.
The net result of successful 2009-2010 exploration programs, up to the
end of April 2010, using a copper cut-off grade of 0.5% copper, is that the
estimated measured and indicated mineral resource saw an increase of 44% in
contained copper, 35% in contained gold and 42% in contained silver over the
last consolidated mineral resource estimate that provided the basis of the
Phase IV PFS released on December 15, 2009. The updated mineral resource
estimate for all undeveloped deposits at the Minto Mine are tabulated below
and are discussed by deposit in the appropriate sections in this release.

"The significant increase in mineral resources at the Minto Mine in a
short period of time reflects the mine's tremendous exploration potential,"
said Stephen Quin, Capstone's President. "Further, with drilling continuing
subsequent to the effective date of this estimate, with the notable success
of the Wildfire discovery, further increases in confidence levels and
potential gains in contained metal can be anticipated as 2010 progresses."
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. There is also no
certainty that these inferred mineral resources will be converted to measured
and indicated categories through further drilling, or into mineral reserves,
once economic considerations are applied.
Change in Mineral Resource Estimates 2009-2010
The 2010 updated mineral resource estimates result in both an overall
gain in tonnage and contained metal, as well as a substantial positive
upgrade in classification in mineral resources over 2009, with only modest
decreases in grades. The third line in the following table shows the net
changes in tonnes, grade and contained metal, while the last line expresses
these changes as a percentage of the total gains. The increase in tonnes and
significant net increase in contained metal is a result of the addition of
significant tonnages of new resources at the Area 2/118 and Ridgetop deposits
coupled with a the new high grade discovery at Minto East, plus some modest
gains at the high grade Minto North deposit.

Area 2/Area 118 Deposit
Previously, Area 2 and Area 118 were treated as separate deposits but,
based upon drilling in 2008 through early 2010, they are now considered one
deposit with the east part (Area 2) interpreted as being thrust over the west
part (Area 118). For the purposes of mineral resource estimation and any
subsequent economic evaluation and, due to their juxtaposition, they are
considered one larger, dismembered deposit. Drilling in 2010 also shows
continuity between the eastern end of the deposit (Area 2) and Copper Keel
North and substantial tonnage gains were made in drilling the former gap
between these two areas. The updated and combined mineral resource for Area
2/118 is tabulated below.

The increases in mineral resources at Area 2/Area 118 versus those
reported in 2009 are the direct result of the infill and step out drilling
conducted during the early part of 2010. This drilling has not only increased
the total size of the resource but has also increased the confidence in those
resources, resulting in significant amounts of mineral resources previously
classified in the inferred category now upgraded to measured and indicated
categories.
The mineral resource estimates for Area 2/118 are quoted on the basis of
a 0.5% copper cut-off in order to allow comparison to prior estimates and
other deposits. The actual cut-offs used for mineral reserve estimation may
vary from this cut-off and will be determined as part of the on-going
pre-feasibility study. Further, some of the Area 2/118 mineral resources are
being contemplated for underground extraction as noted in prior disclosure,
which would use a significantly higher cut-off grade than that discussed
herein. However, until a determination is made as to the ultimate size of the
proposed open pit and extraction of underground mineral resources, it is not
possible to provide guidance as to the potential mineable tonnage and grade
for this deposit.
Dr. Wayne Barnett, Ph.D, Pr.Sci.Nat and Marek Nowak, P.Eng. of SRK
Consulting (Canada) Inc. ("SRK") estimated the mineral resources for the
combined Area 2/Area 118 deposit in July, 2010 and the results are effective
as of July 26, 2010. The estimate was completed in Gemcom Software GEMS(C)
using a three dimensional block model (10m by 10m by 3m (vertical) block
size). The mineralization was interpreted into 17 different domains and
wireframes were created and geostatistical analysis was completed on the
assay and 1.5m composite data for each of the metals. The grades for copper
and gold were interpolated into the block model using ordinary kriging method
while the inverse distance squared method was used for comparative purposes.
Whereas the silver grades were interpolated using the inverse distance
squared method only. Interpolated results are reported in measured, indicated
and inferred categories and were based on continuity of the mineralization
and sample density.
Ridgetop
Ridgetop is a near surface, more moderate grade deposit that is expected
to have lower strip ratios than the other deposits identified to date at the
Minto Mine. The updated mineral resource estimate for the Ridgetop deposit is
tabulated below using a 0.5% copper cut-off. Actual cut-offs used for mineral
reserve estimation may vary from this cut-off and will be determined as part
of the on-going pre-feasibility study.

As for Area 2/118, the Ridgetop drill programs in 2009 and 2010 resulted
in a significant percentage of the Ridgetop mineral resource being upgraded
from the inferred class to measured and indicated class.
Dr. Barnett and Mr. Nowak of SRK estimated the mineral resources at
Ridgetop in May, 2010, and the results are effective as of the July 26, 2009.
It was completed in Gemcom Software GEMS(C) using a 3 dimensional block model
(10m by 10m by 3m (vertical) block size). The mineralization was interpreted
into seven different domains and wireframes were created and geostatistical
analysis was completed on the assay and 1.5m composite data for each of the
metals.
The grades for copper and gold were interpolated into the block model
using ordinary kriging method (and inverse distance squared method for
comparative purposes), whereas the silver grades were interpolated using the
inverse distance squared method. Interpolated results are reported in
measured, indicated and inferred categories and were based continuity of the
mineralization and sample density.
Minto North Deposit
The Minto North deposit comprises relatively near surface, higher grade
copper-gold mineralization discovered in 2009. Late in that same year a
program of infill drilling was completed to upgrade the mineral resource
classification from largely inferred to now after this new estimate to being
largely measured class. The new mineral resource estimate for the Minto North
deposit, using a 0.5% copper cut-off, is tabulated below. Actual cut-offs
used for mineral reserve estimation may vary from this cut-off and will be
determined as part of the on-going pre-feasibility study.

Mr. Garth Kirkham, P.Geo. of Kirkham Geosystems Ltd. ("KGL") estimated
the mineral resources at Minto North in April, 2009. It was completed in
MineSight(R) using a 3 dimensional block model (10m by 10m by 3m (vertical)
block size). The mineralization was interpreted into 6 different domains,
wireframes were created and geostatistical analysis was completed on the
assay and 1.5m composite data for each of the metals.
Minto East Deposit
The Minto East deposit is a new discovery made in late 2009 and comprises
moderately deep, higher grade copper-gold mineralization. This is the first
mineral resource estimate for the Minto East deposit but a substantial
program of infill drilling is still underway and a new mineral resource
estimate is planned for later in 2010. Using a 0.5% copper cut-off this
preliminary estimate is tabulated below.

The mineral resource estimate at Minto East was completed in June, 2010.
It was completed in MineSight(R) using a 3 dimensional block model (10m by
10m by 3m (vertical) block size). The mineralization was interpreted into one
mineralized zone, wireframes were created and geostatistical analysis was
completed on the assay and 1.5m composite data for each of the metals.
The mineral resource estimates for Minto East are quoted on the basis of
a 0.5% copper cut-off in order to allow comparison to other deposits.
However, the Minto East mineral resources are being contemplated for
underground extraction as noted in prior disclosure, which would result in a
significantly higher cut-off grade being used than that discussed herein.
Until the results of the pre-feasibility study currently underway are
available, it is not possible to determine the most appropriate cut-off grade
for the Minto East deposit. However, as noted in a press release dated June
23, 2010, a cut-off grade in the range of 1.5% copper may be in the range to
be used for determining mineral reserves. At a 1.5% copper cut-off grade, the
Minto East mineral resource is as follows:

Resource Estimation Methodology
SRK Consulting (Canada) Inc.: All mineral resources reported herein for
Area 2, Area 118 and Ridgetop were estimated by SRK. Marek Nowak (P. Eng.),
and Wayne Barnett (Pr.Sci.Nat.) of SRK are the Independent Qualified Persons
under National Instrument 43-101 responsible for the mineral resource
estimates.
The resource estimates for Area 2, Area 118 and Ridgetop were based on
revised geological models. The revision of the models was undertaken by SRK
using historical and newly completed geological drilling logs and assay
sample results for each of the deposits. All geological models and
estimations were undertaken using the Gemcom Software GEMS(C). A total of 235
drill holes were used to construct the geology and estimate the resource for
the combined volume of Area 2 and Area 118. The Ridgetop model was
constructed from 163 drill holes. The geology is similar for all deposits,
with mineralization concentrated in shallow dipping zones of foliated
granodiorite along which grade continuity can be demonstrated. Each deposit
has between seven and nine such ore zones. The grades were estimated for each
ore zone separately, with independently derived kriging parameters. The
estimated block model for each deposit consists of 10m by 10m by 3m block
sizes. Resource classification categories were designed from continuity of
the mineralization and sample density. The open pit mineral resources are
reported within a Whittle shell designed from an NSR model and based on
optimistic parameters.
Kirkham Geoystems Ltd: All mineral resources reported herein for Minto
North were estimated by Kirkham Geosystems. Garth Kirkham (P. Geo.) is the
Independent Qualified Person under National Instrument 43-101 responsible for
the Minto North mineral resource estimate. The Minto North Deposit was
constructed using 30 drillholes resulting in 3 relatively flat lying
mineralized zones (i.e. 115, 120 and 130 zones) and 3 small splayed zones.
The grades were estimated for each zone separately with independently derived
kriging parameters. The estimated block model consisted of 10 x 10 x 3 m
block sizes using 1.5m composites. Resource classification categories were
designed from continuity of the mineralization and sample density.
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 of
Capstone Mining Corp. The exploration activities at the Minto project site
are carried out under the supervision of Brad Mercer, P. Geol., V.P.
Exploration of 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-IPL of Vancouver.
