Sherwood Reports Further High Grade Copper-Gold Results From Areas 2 & 118 at Minto Mine
22 August 2008 - 4:58AM
Marketwired Canada
Sherwood Copper Corporation (TSX VENTURE:SWC)(TSX VENTURE:SWC.DB)today announced
results for 15 further drill holes from its 2008 exploration program at the high
grade Minto copper-gold mine in the Yukon. Highlights from this latest batch of
results include continued high grade intercepts in the Area 118 deposit,
including a hole that equals the prior highest grade intercept in Area 118,
returning 4.7% copper and 1.2g/t gold over 8.5m. Also of significance is the
discovery of further high grade mineralization in wide spaced drilling on the
south margin of the Area 2 deposit, expanding the mineralization in that
direction, and a strong intercept from the Copper Keel prospect. Highlights from
this latest batch of 15 holes are summarized in the table below while complete
assay results for the fifteen holes reported herein are attached.

"Our in-fill and step-out drill program in the high grade Area 2 and Area 118
copper-gold deposits at the Minto Mine continues to reap considerable rewards,"
said Stephen Quin, President & CEO of Sherwood Copper and Minto Explorations
Ltd. "The Area 2 deposit is being expanded to the south, at relatively shallow
depths, while Area 118 is returning consistent, very high grade copper and gold
values," he said. "The results from the Copper Keel area, an early stage
prospect, are particularly encouraging since they suggest that the Area 2 and
Copper Keel mineralization may link up, providing considerable additional
opportunities for further resource increases."
2008 Drill Program
The 2008 drill program has evaluated the Area 2, Area 118 and Ridgetop deposits
and several other targets in a program comprised of a balance of infill,
step-out and exploration drilling. To date, 116 holes have been completed in
2008, with the primary objective of expanding the known resources at Area 2,
Area 118 and Ridgetop, and increasing confidence in those resources in support
of future feasibility studies geared to increasing high grade production at the
Minto Mine over and above the levels already achieved.
In addition, as announced on August 5, 2008, Sherwood plans to explore the
possibility of linking the Area 2, Area 118 and Ridgetop mineralized systems
together, into one large deposit following the release of resource estimates at
cut-offs lower than the current mining operation that suggested potential for a
much larger, more moderate grade scenario with a lower strip ratio. As part of
this evaluation, Sherwood has completed a substantial part of the wide spaced
pattern designed to evaluate this potential, and results are pending for these
drill holes.
As of August 20, 2008 a total of 23,057 metres of drilling has been completed in
116 holes in 2008. Seventeen holes for 4,470 metres were completed during the
winter, the results of which were reported on May 14, 2008. A further 99 holes
for 18,587 metres have been completed since then and drilling is still ongoing,
but nearing completion of the program. Copper and gold assay results have been
received for only 51 of the 116 holes completed to date, results for a further
15 of which are reported herein.

for 2008.

2008 Discussion of Results to Date
The 2008 drill program is proceeding very well and is nearing completion. A
drill statistics table attached to this release details how the drilling in 2008
is distributed thus far, while a synopsis of results is discussed below. It is
anticipated that drilling will resume early in 2009.
Area 118: Infill and partial step-out drilling at Area 118 has returned
excellent results with 5 of 7 holes reported in this latest batch of assay data
grading better than 2% copper over significant intervals and 3 holes reporting
greater than 3% copper. Results from hole 08SWC-316 matched exactly the previous
highest grade intersection reported at Area 118 (08SWC-310 reported on July 21)
grading an impressive 4.71% copper and 1.19g/t gold over 8.5m (27.9ft). This
hole is located more than 120m north-northeast of hole 08SWC-310. Hole 08SWC-313
also intersected very high grade mineralization, grading 3.12% copper and
1.37g/t gold over 8.1m (26.6ft). Hole 08SWC-307 intersected even higher grades,
with 6.53% copper and 2.48g/t gold over an interval of 2.4 metres (7.9ft).
Area 2: Three of the four holes drilled on the east perimeter of the previously
known limit of the Area 2 deposit intersected between 1% and 2% copper over
significant intervals. Three holes drilled on the south perimeter of the deposit
also intersected similar grades of copper mineralization at shallower depths.
These results indicate potential to increase the Area 2 mineral resource beyond
that announced June 17, 2008. The details of these intersections are in the
table appended to this news release.
Copper Keel: Preliminary geological interpretations suggest there is probable
continuity between the Area 2 deposit and the Copper Keel prospect located to
the east of Area 2. Hole 08SWC-312 graded 2.13% copper and 0.80g/t gold over
11.6 metres (38.1ft) and supports that postulation. More drilling would be
required to conclusively prove a link between these two deposits.

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 northwestern British
Columbia. Sherwood expects to lever off its successful development of the Minto
Mine and rapidly 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. The exploration activities at the Minto project site are carried
out under the supervision of Brad Mercer, P. Geol., V.P. Exploration for
Sherwood.
The analytical method for copper and silver performed by SGS Laboratories under
a contract arrangement at the Minto Mine Site, Yukon includes digestion in aqua
regia followed by absorption spectroscopy. Gold is measured using fire assay
with atomic absorption spectroscopy; analysis is performed by SGS Laboratories
at Red Lake, Ontario. When visible gold is noted in drill core samples or
regular analytical values exceed 5 grams per tonne, the pulp and screen metallic
assay method is used to determine total gold content and gold content of
different size fractions. This is considered industry best practice when dealing
with coarse gold mineralization where a nugget effect is suspected. The result
of the pulp and screen metallic assay is accepted as the most representative
value and used in the assay database for resource calculations. Blank and
standard samples are added to all sample shipments prior to submittal to the lab
for quality assurance and quality control. If more than two check samples assay
outside of expected ranges, the work order is re-assayed. After the completion
of planned drill programs, random check assays will be carried out by ALS Chemex
of North Vancouver, BC.
Assay intervals reported herein are drill core lengths unless otherwise stated.
Because the known deposits are essentially flat lying and most drill holes
reported to date are vertical, true widths are generally expected to be the same
as reported core lengths unless otherwise stated.
