Sherwood Reports Higher Copper Production Forecast for 2009 & Updated Resource Estimates

Sherwood Copper Corporation (TSX VENTURE:SWC)(TSX VENTURE:SWC.DB) today
announced that it has completed a National Instrument 43-101 compliant Technical
Report that details two significant developments at its high grade Minto
copper-gold mine in Yukon, Canada. Firstly, through rescheduling the open pit
currently being mined on the Minto Main deposit, higher grade copper production
has been brought forward from 2010 to 2009 as compared to prior guidance.
Secondly, the Technical Report details the updated mineral resource estimates
previously announced on June 17, 2008, which increased mineral resources by
approximately 50% over those announced a year ago and which should provide the
basis for further increases in mine life and/or production. However, in addition
(and for the first time), details of the mineral resources at cut-off grades
lower than 0.5% copper are provided, which indicate significant potential for
large tonnages of medium grade mineral resources at the Minto Mine.


"The increased production in 2009 is a further example of Sherwood's relentless
pursuit of value for its shareholders," said Stephen Quin, President & CEO of
Sherwood. "More production sooner should mean more value for our shareholders,"
he said. "Further, the previously announced 50% increase in mineral resources at
the high grade Minto Mine is a very positive development. The significantly
increased mineral resource suggests potential for a longer mine life and/or
further increases in production, beyond the rescheduled production announced
today. However, the first time disclosure of substantial mineral resources at
lower cut-off grades, which still results in mineral resource grades well above
any operating copper mine in western Canada, provides a glimpse of what could be
a materially larger opportunity at the Minto Mine, and is something that
warrants continued investigation."


Highlights

Highlights of the information contained in the Technical Report include the
following, based on the assumptions set out below:


1. Higher grade production moved forward from 2010 to the end of 2008 and all of
2009, resulting in 55 million pounds of copper production in 2008 and 70 million
pounds of copper production in 2009, a 35% increase in that year;


2. Operating costs, after by-product credits and offsite costs such as
concentrate shipping, insurance, treatment and refining charges, of C$0.80 to
C$0.89 per pound, life of mine;


3. Pre-tax net present value of $364 million to $659 million at a 0% discount
rate, depending on metal prices and, at the same discount rate, after tax net
present value of $311 million to $522 million;


4. Pre-tax net present value of $273 million to $386 million at a 10% discount
rate, and an after tax NPV of $241 million to $372 million at the same discount
rate;


5. At a 0.5% copper cut-off, measured and indicated resources of 19.28 million
tonnes grading 1.42% copper, 0.51g/t gold and 5.4g/t silver, containing 604.5
million pounds of copper, 310,000 ounces of gold and 3.3 million ounces of
silver;


6. At the same cut-off, an additional inferred resource of 15.07 million tonnes
grading 0.88% copper, 0.25g/t gold and 0.25g/t silver containing 293.6 million
pounds of copper, 120,000 ounces of gold and 1.26 million ounces of silver;


7. These resources represent a 50% increase over those announced a year ago and
a 140% over those announced two years ago and do not incorporate the results of
any of the 2008 drilling;


8. Proven and probable mineral reserves of 9.13 million tonnes grading 1.93%
copper, 0.74g/t gold and 7.7g/t silver containing 389.2 million pounds of
copper, 216,900 ounces of gold and 2.3 million ounces of silver;


9. These reserves are based on 2006 drilling and mineral resource estimates and
hence do not incorporate the 50% increase in resources announced herein, nor any
of the results of the 2008 drilling currently underway;


10. Given that significant lower to medium grade mineralization was intersected
up and down drill holes from the higher grade intercepts used to estimate the
mineral resources at a 0.5% copper cut-off, and that almost all of this lower to
medium grade mineralization would fall within any pit targeting the higher grade
mineralization, this would potentially result in more tonnes and a lower strip
ratio within the planned open pits were a lower cut-off grade used to estimate
resources;


11. At a 0.2% copper cut-off, mineral resources are estimated at 30.36 million
tonnes grading 1.03% copper, 0.35g/t gold and 3.8g/t silver, containing 689.4
million pounds of copper, 340,000 ounces of gold and 3.75 million ounces of
silver;


12. Additional inferred mineral resources, at the same cut-off, are estimated at
42.6 million tonnes grading 0.53% copper, 0.13g/t gold and 1.6g/t silver
containing 496.5 million pounds of copper, 180,000 ounces of gold and 2.18
million ounces of silver;


13. These mineral resource estimates exclude any of the results of 2008
drilling, which is in-fill drilling these areas to upgrade the confidence level
in the mineral resources, as well as stepping out to potentially expand the
mineral resources since the area drilled to date represents only a portion of
the overall mineralized system identified at the Minto Mine;


14. A new pre-feasibility study will evaluate opportunities to convert as much
as possible of the mineral resources defined in 2007 and 2008 into reserves, as
well as to further increase mill throughput, which study should be complete by
mid-2009;


15. Sherwood is targeting sustained production in the range of 60-70 million
pounds of copper per year from its Minto Mine.


Technical Report

The Technical Report was completed for Minto Explorations Ltd. ("MintoEx") under
the supervision of SRK Consulting (Canada) Inc. ("SRK"), and represents an
update to the Pre-feasibility Study ("PFS") completed under SRK's supervision,
the results of which were announced on December 12, 2007 and filed on SEDAR on
December 18, 2007. The Technical Report uses actual performance and cost
information up to the end of June 2008 and re-forecasts costs and performance
for July 2008 onwards based on actual experience as well as expectations based
on that experience. The Technical Report will be filed on SEDAR within 1-2 days
of the date of this release.


Rescheduled Production Profile

As previously disclosed, Sherwood's wholly owned subsidiary, MintoEx, has been
working towards a rescheduled extraction profile for the open pit on its high
grade Main Zone at the Minto Mine, as compared to the production profile set out
in the December 2007 PFS. The PFS forecast peak copper production in 2010.
However, as a result of schedule modifications to the open pit on the Main Zone,
the high production in 2010 has been brought forward into the latter part of
2008 and the balance in 2009. The remainder of the Main Zone and all of the Area
2 deposit are scheduled to be mined consecutively thereafter. This rescheduled
mine plan is based on resources drilled to the end of 2006 and does not evaluate
any of the resource additions delineated in 2007 nor does it incorporate the
results of 2008 drilling. The revised production schedule is summarized in the
table below.

Based on successful exploration in 2007, which increased resources by
approximately 50% over those considered in this Technical Report, and the
results of 2008 drilling, Sherwood is targeting sustained production of 60-70
million pounds of copper per annum in a high grade scenario (using a resource
estimate with a 0.5% copper cut-off).


Sherwood is progressing towards this production objective by working to convert
the 2007 resource additions to reserve standards in 2008, testing for increases
to these resource areas in 2008 and conducting the required resource estimation,
mine planning, metallurgical and environmental work required to prepare a new
pre-feasibility study before the middle of 2009 while, in parallel, undertaking
the required permitting activities to allow this increased production. Mine
planning will be focused on displacing lower grade ore in the current production
schedule with higher grade mineralization discovered subsequently to the PFS,
and postponing the use of stockpiles to bridge the production between mining of
the Main Zone and the Area 2 deposit with low-strip ratio, higher grade
mineralization from the new resource areas discovered in 2007-08. In addition,
prior evaluations have suggested that the current ore processing facilities
could potentially be expanded to 4,000 to 5,000 tonnes per day with only modest
modifications.


The combination of more higher-grade mineral resources and higher throughput
should make Sherwood's objective of 60-70 million pounds of sustained copper
production from the Minto Mine achievable.


Updated Project Economics

In parallel with its rescheduled mine production, MintoEx and SRK took the
opportunity to update operating and capital costs to reflect actual performance
up to and including the end of June 2008, and to reforecast performance,
operating costs, capital requirements and commodity prices based on experience
to date and reasonable expectations going forward. As has been previously
reported, the mineral reserves extracted to date from the Minto Main Zone are
meeting or exceeding expectations, the process plant is now running at above
design capacity on a sustained basis, a permit amendment was recently issued to
allow processing of the Main Zone at up to 3,200 tpd of ore, there are now nine
months of commercial production cost data available on which to base cost and
performance expectations, and grid power is expected to be available during the
fourth quarter of 2008, significantly reducing operating costs. These
developments, along with others not listed here, have allowed a comprehensive
reassessment of the project economics, which are detailed in the Technical
Report and highlights presented below.

Cases 2 and 3 were run at 15% and 30% lower metal prices than used for Case 1.
The other main economic factors used in the cash flow analysis were:


1. CAD:USD exchange rate of 1:1 (parity) for 2008; 1.05:1 for 2009; and 1.10:1
beyond 2009


2. A discount rate of 10%;

3. Variable metal pricing, with copper having declining forward pricing
(backwardation) and gold and silver were kept flat as opposed to escalating
(contango) as the forward curve indicates;


4. Nominal 2008 dollars; and

5. No inflation.

Costs, revenues and taxes were calculated for each period in which they occurred
rather than at the actual date of payment. For example, taxes were calculated
each month in the model even though they are actually paid only once per year,
in the year following the year accrued. It must be noted that the net present
value ("NPV") calculations in the financial model were done using 2008 as the
starting year and do not take into account approximately $150M in capital spent
in 2006 and 2007 for plant and mine construction. This methodology is
appropriate but only looks at the project going forward from the beginning of
2008 and, therefore, shows high returns.

Additional details on the financial parameters for each of the three cases are
attached to this news release, while comprehensive information on assumptions
and outcomes are contained in the Technical Report.


"The financial analysis for the Minto Project demonstrates a robust project in
all scenarios," said Mr. Quin. "Using the current forward curve for copper and
flat precious metal prices, the Minto Mine generates an exceptionally positive
cash flow. There are opportunities to further increase project NPV through the
conversion of the mineral resources discovered and delineated in 2007 and 2008
to reserves, the process for which is underway."


Mineral Resources at a 0.5% Copper Cut-off

Updated mineral resource and mineral reserve estimates were announced on June
17, 2008 and the Technical Report provides additional details in respect of
those estimates. Net of all adjustments, contained copper in the mineral
resource estimate increased by 50% and precious metals by approximately 40% as a
result of drilling in 2007. This follows on from a 60% gain in contained copper
in mineral resource estimates based on drilling in 2006, for a 140% gain in
copper resource estimates in two years. The mineral resource tonnages are being
reported inclusive of the mineral reserves.

This resource estimate contains an estimated 604.5 million pounds of copper,
310,000 oz of gold and 3.3 million oz of silver in the measured and indicated
mineral resource categories using a 0.5% copper cut-off, with an additional
293.6 million pounds of copper, 120,000 oz of gold and 1.26 million oz of silver
in the inferred mineral resource at that same cut-off, representing an increase
of 50%, 40% and 38% in total contained copper, gold and silver, respectively.


"Given that the available mineral resource estimate has increased by 50% since
the resource estimate used in the PFS and that a 25,000m drill program is
underway to upgrade the confidence in and expand these resources, a new
pre-feasibility study is warranted to evaluate the economic potential of these
new resources, once the 2008 drill program is completed," said Mr. Quin. "There
is excellent potential for both an increased mine life and further increases in
production given the tremendous exploration success at the high grade Minto
copper-gold mine."


Sherwood has retained SRK to supervise the preparation of a new pre-feasibility
study that will incorporate the results of the 2007 and 2008 drill programs,
updated resource estimates, mine planning, metallurgical testing and
environmental studies. The new study is expected to be completed by mid-2009.


Mineral Reserves

Mineral reserve estimates remain as announced June 17, 2008 and can be
summarized as follows, representing the previously announced reserve for the
Minto Main deposit and the Area 2 deposit, less mining that has taken place in
2006 and 2007. See the June 17 news release for additional details. Note that
reserves have not been updated to incorporate the higher mineral resources
contained in this news release; this will be done as part of a new
pre-feasibility study, as discussed below.

Mineral Resources at Lower Cut-off Grades

Whereas there is very little lower grade mineralization in and around the Minto
Main deposit, currently being mined, the southern deposits such as Area 2, Area
118 and Ridgetop host extensive zones of lower to medium grade mineralization
above and between higher grade zones for which resource estimates have been
announced to date. Since this lower grade mineralization lies up and down the
existing drill holes, and does not represent lateral projections to any
significant degree and would most likely fall within any pit designed to extract
the higher grade zones, Sherwood has, for the first time, assessed the mineral
resources at lower cut-offs than those previously considered. Mineral resource
estimates at a 0.2% copper cut-off and 0.3% copper cut-off are summarized below,
while details of mineral resource estimates at all cut-off grades calculated and
the estimation methodology are detailed in the Technical Report.

measured and indicated mineral resource categories using a 0.2 and 0.3% copper
cut-off, with an additional 435.8 to 496.5 million pounds of copper, 160,000 to
180,000 oz of gold and 1.9 to 2.2 million oz of silver in the inferred mineral
resource at the same cut-offs.


"While the overall grades in the resource estimates above are lower than
currently being mined at the Minto Mine, they average approximately twice that
of currently operating copper mines in British Columbia," said Mr. Quin. "These
resources would require additional work to demonstrate positive economics;
nevertheless, they do suggest an interesting opportunity for a considerably
larger scale operation than would be contemplated at the higher cut-off grades
currently being used. Further, these resource estimates encompass only a modest
portion of what may be a much larger mineralized system. Further drilling is
required to evaluate the potential continuity of the large untested areas
between the currently defined mineral resources."


Sensitivities

Both the pre-tax and after taxation cash flow models show the project is most
sensitive to changes to the copper grade. This sensitivity is somewhat mitigated
in the mine plan by the significant use of stockpiles to allow the early
extraction of higher grade ore and the ability to blend different grades to
provide a consistent mill feed. These two features of the life-of-mine plan are
important in maximizing the economics of the project. In Case 1, a 20% drop in
copper grade yields a $112 M (29%) drop in after-tax NPV10%. Diligent grade
control practices will be important in achieving undiluted mill feed, especially
in Area 2 where the mineralized zones are smaller and more numerous than those
found in the Main pit.


Metal prices demonstrate the second greatest sensitivity. In Minto's case, the
metal prices are buffered by the fact that a significant portion (approximately
50%) of its production is already hedged until late 2011, so a reduction or
increase in the market price has a tempered affect on the NPV. Even with this
forward sale arrangement, a 20% decrease or increase in copper price changes the
after-tax NPV10% by 25%.


A 20% reduction in operating cost yields a $45 M (12%) increase in after-tax
NPV10%. Many of Minto's major operating expenses including mining, explosives,
treatment charges and refining charges and concentrate transport are covered by
contracts and, therefore, offer considerable protection from variances in the
next 2 to 4 years.


As most of the capital expenses for the mine and expansions have already been
incurred, the project is not sensitive to CAPEX.


Project Risks

The following risks have been identified for the Minto Mine:

1. Exchange rates, metal prices and external influences: MintoEx has no control
over exchange rates and their impact on the economics of the operation is
significant. Metal prices are also not controllable, other than by forward sales
contracts, and can have an appreciable effect on project return.


2. Process Capacity: The ability of the mill to be modified to 3,500 tpd is a
risk, as there may be certain unit operations that could create bottlenecks to
the operation that have not been identified.


3. Water management: Both the lack of water and the overabundance of water are
potential issues for the mine. A lack of water may be an issue during the in-pit
co-deposition of tailings in the Main pit as water will be lost. An
overabundance of water could attract higher water treatment costs.


4. Grade control: The Area 2 deposit is made up of several zones of ore that are
not as continuous and thick as the Main zone. As a result, a very thorough and
proactive grade control program will be necessary to reduce dilution. The NPV of
this project is very sensitive to copper grade, so excessive dilution will have
a serious negative impact on the project economics.


5. Permitting: The plan for the mining of the Area 2 deposit, and handling of
the tailings and waste rock generated therefrom, requires modifications to
existing permits, which may not be granted or may take longer than expected.


Project Opportunities

The following opportunities have been identified for the Minto Mine:

1. Optimization of mine plan: The mine plan has not been fully optimized and it
is likely that further scheduling work will smooth out some of the grade and ore
extraction variations and provide higher grade ore sooner, with delayed waste
mining.


2. Resource additions: The resource updates contained in this report show
considerable additional mineralization that has not been considered in the
life-of-mine plan summarized in this report. Extensive drilling is underway in
2008 to upgrade the confidence in these new resources, to attempt to increase
them and to test new targets. A further update to the life-of-mine plan will be
completed once the 2008 results are available, and offers opportunities for
further increases in grades, potential rescheduling of the different zones to
optimize project economics, etc.


3. Exploration target potential: There are several interesting exploration
targets on the Minto property. MintoEx has plans to further explore these
targets with the hope that they will become resources and eventually reserves.
There is absolutely no guarantee these targets will ever be economic to extract;
however, the past exploration record at Minto is a positive indication of
further potential.


4. Underground mine potential: MintoEx has identified some deeper exploration
targets that may have the potential for underground mining. If these targets are
added to Minto's resources, a study should be undertaken to determine if the
deposits are sufficient in grade and volume to support underground development.


5. Waste deposition in the Minto Valley: The Minto valley to the west and
south-west of the Main pit offers a viable waste rock dump alternative that will
provide the mine with a significant cost savings, by reducing the distance and
elevation of the waste rock truck hauls.


6. Processing efficiency: As the Minto ore is better understood, the processing
plant may be further optimized to increase recovery, improve concentrate grade
or increase throughput.


7. Cost efficiencies: MintoEx operating personnel are evaluating areas where
costs can be improved. The largest cost centre is mining, followed by
processing.


Plan for a Comprehensive Updated PFS

As noted above, Sherwood is in the process of completing an extensive drill
program designed to (a) upgrade the confidence level in the resources detailed
above, (b) to expand those resources and (c) to test new targets. Based on the
results of the 2008 drill program, Sherwood will complete new resource estimates
that will support mine planning to bring these resources into production plans.
The objective of these mine plans will be to bring higher grades forward,
possibly by mining more than one deposit in parallel, and by deferring lower
grade and stockpiled material until the end of the mine life. In parallel,
Sherwood aims to conduct metallurgical testing on each of the new deposits
discovered, as well as carry out environmental programs. These new resources,
mine plans, metallurgical and environmental studies, along with any other
information will be used to support a comprehensive updated pre-feasibility
study, supervised by SRK, scheduled for completion by mid-2009. As also noted
above, this study will evaluate further increases to the throughput rate for the
process mill. Overall, by focussing on higher grades and higher throughputs,
Sherwood's objective is to demonstrate sustained production at a rate of 60-70
million pounds of copper per year in this study.


At the same time as carrying these activities related to the preparation of a
new pre-feasibility study, Sherwood aims to continue the evaluation of the
potential of the Minto property to host a significantly larger, more moderate
grade deposit.


About Sherwood Copper

Sherwood Copper's objective is the profitable production of base and precious
metals from high grade, open pit mines in Canada. Sherwood's first operating
mine, the high grade Minto copper-gold mine in Yukon, Canada, was built on
budget and ahead of schedule. The Minto Mine is one of the highest-grade open
pit copper-gold mines in the world, and is forecast to be a low cost producer.
Aggressive exploration on the Minto property has yielded significant success,
providing Sherwood the opportunity to 'grow from within' by expanding the
resource and reserve base, potentially leading to further production increases.
To further accelerate its production growth, Sherwood intends to pursue merger &
acquisition opportunities that fit its business model and, in May 2008, Sherwood
acquired 100% ownership in Western Keltic Mines (now Kutcho Copper Corp.), owner
of the high-grade Kutcho copper-zinc-gold-silver deposit in north-western
British Columbia. Sherwood intends to lever off its successful development of
the Minto Mine and advance the Kutcho project to a production decision.


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 & CEO for Sherwood Copper
Corporation, who has reviewed the content of this press release. The exploration
activities at the Minto project site are carried out under the supervision of
Brad Mercer, P. Geol., V.P. Exploration with Sherwood. The mineral resources
discussed in this news release were estimated by Lions Gate Geological
Consulting Inc. (LGGC). Susan Lomas, P. Geol. of LGGC is the Qualified Person
under National Instrument 43-101 responsible for the estimates and has reviewed
the information in this release in respect of mineral resource estimates.
Mineral reserves were calculated by MintoEx geology and engineering staff under
the supervision of Dan Russell, P. Eng., Manager of Mining at the Minto Mine,
who is the Qualified Person under National Instrument 43-101 responsible for the
mineral reserve estimate, as detailed in the June 17, 2008 news release. David
Hendriks, P.Eng., of TechPro provided the metallurgical information used in the
Technical Report based on actual operating experience at the Minto Mine and
prior test work reported in the PFS. The operating and capital cost information
used in the Technical Report were provided by MintoEx operating personnel, under
the supervision of Kevin Weston, Chief Operating Officer of Sherwood, and
Randall Thompson, General Manager of the Minto Mine. The economic analysis
information from the Technical Report referenced in this news release was
reviewed by Gordon Doerksen, P.Eng. of SRK.


Minto Main deposit reserve estimate was compiled using the updated mineral
resource model provided by LGGC, hereby referred to as the "Model". The Model
was imported into Mintec's MineSight(R) software for the reserve calculation.
The mineral resource estimate was verified using MineSight(R) to ensure the
import was successful. The mineral reserve calculation was bounded by the 2007
year-end survey surface (122007 YE Pit Surface.msr) and the most current
ultimate pit design surface (ph5 nov1.msr). Furthermore, a cut-off grade of
0.62% Copper was used. The absence of these factors is justified on account of
historical performance showing good mining reconciliation against the past
model. The mineral reserve summary is based on measured and indicated mineral
resource classifications in the model only, totalled within ore zones 2, 4, 5,
and 8 in the Minto Main deposit (as established by in the December 2007
Pre-feasibility Study), and bounded by the aforementioned surfaces and
assumptions. Mineral resource categories and definition of ore zones in the
Model were established by the relevant QP's for each resource model, as defined
herein.


Details of the historical Area 2 mineral resource and mineral reserve estimate
are provided in the Technical Report for the Minto Pre-feasibility study,
available on SEDAR, the results of which were announced on December 12, 2007.
The current Area 2 mineral reserves are based on this historic mineral resource
and have not been updated to reflect the increased Area 2 mineral resource
discussed in this release nor the results of drilling in 2008.


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.
