Sherwood Announces Significant Increase in Copper-Gold Resources at Minto Mine, Yukon

50% Increase in Contained Copper in Resource Provides Strong Foundation for Further Growth

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 17, 2008) - Sherwood Copper Corporation (TSX VENTURE:SWC)(TSX VENTURE:SWC.DB) today announced the results of National Instrument 43-101 compliant, mineral resource estimates for its high grade Minto copper-gold mine in Yukon, Canada. New mineral resource estimates were completed for the Area 118 and the Ridgetop deposits, while those for the Main Minto and Area 2 deposits were updated to incorporate the results of 101 new holes drilled across these four deposits in 2007. These estimates do not include results from any of the drilling conducted in 2008, where more than 51 holes have been completed to date and results for 16 have been released; assays are pending for the balance. Mineral resources and reserves were also updated to account for mining in 2006-07. Net of all adjustments, contained copper in mineral resources 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 resources based on drilling in 2006, for a 140% gain in copper resources in two years.

This resource contains 604.7 million pounds of copper ("Cu"), 320,000oz of gold ("Au") and 3.3million oz of silver ("Ag") in the measured and indicated mineral resource categories using a 0.5% copper cut-off, with an additional 294.4 million pounds of copper, 120,000oz 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.

"Sherwood's exploration team delivered another stellar year at the Minto Mine," said Stephen Quin, Sherwood's President & CEO. "Contained copper in resources increased 50% in one year and 140% in two years. While most of the gain in 2007 was in the inferred category, we are already infill drilling the two 2007 discoveries (at Area 118 and Ridgetop) to upgrade the confidence level in these areas, as well as continuing to pursue opportunities for yet further increases in resources at the Minto Mine," he said. "With these results in hand, not only are we looking to continue to increase resources, but also to take advantage of the potential to increase the throughput capacity of the Minto mill by grinding coarser, which could provide opportunities to increase production levels well beyond those currently planned. In addition, we also plan to evaluate the resource potential at cut-offs below 0.5% copper, to determine the overall potential of this mineralized system."

Minto Main Deposit

The measured and indicated mineral resource estimate for the Minto Main deposit using a 0.5% copper cut-off is 7.97 million tonnes at a grade of 1.84% Cu, 0.66g/t Au and 7.6g/t Ag for a total contained metal of 323.3 million pounds of copper, 170,000oz of gold and 1.96 million oz of silver. Approximately 1.24 million tonnes of mineral resources were removed from the Minto Main deposit by open pit mining during pre-stripping and production mining from the Minto open pit up to Dec. 31, 2007. Mineral resources are not mineral reserves and not all of the mined resource was processed through the Minto mill; some material was placed in stockpiles for later processing. Reserve reconciliation for the Minto Mine is discussed in the section below entitled "Minto Mine Reserve Reconciliation".

The Mineral Resource estimate for the Minto Mine was originally completed by Gary Giroux P.Eng of Giroux Consulting Ltd. in April 2006. Ali Shahkar P.Eng. of Lions Gate Geological Consulting Ltd. (LGGC) updated the Mineral Resource estimate for the Main Zone in February 2008 to include data from five new drill holes and the open pit outline as of December 31, 2007. The estimate was completed in Gemcom Software (Gems) using a three dimensional block model (5m by 5m by 3m (vertical) block size) and ordinary kriging method.

Area 2 Deposit

The measured and indicated mineral resource estimate for the Area 2 deposit using a 0.5% copper cut-off is 11.3 million tonnes at a grade of 1.13% Cu and 0.40g/t Au for a contained metal total of 281.4 million pounds of copper, 150,000oz of gold and 1.4 million oz of silver. This represents a more than 33% gain in contained copper and nearly a 25% gain in ounces of gold and a 31% gain in ounces of silver in the measured and indicated categories over the previous resource estimate for Area 2. An additional inferred mineral resource contains 3.5 million tonnes at a grade of 0.77% Cu, 0.25g/t Au and 2.54g/t Ag or 59.9 million pounds of copper, 30,000oz of gold and 290,000 oz of silver, inclusion of which would significantly increase the net gains in contained copper, gold and silver versus prior estimates. The largest gains were made in the southwest, where Area 2 transitions into Area 118 in an approximately 100m wide corridor. All of the mineral resources in this transition corridor were assigned to Area 2. In addition, some additional gains were made in the south to southeast side of Area 2. Area 2 and Area 118 are essentially different segments of a much larger deposit subsequently separated by a zone of late brittle faulting.

Susan Lomas, P.Geo. of LGGC estimated the mineral resources for Area 2 in June, 2008. The estimate was completed in Gemcom Software (Gems) using a three dimensional block model (15m by 15m by 3m (vertical) block size). The mineralization was interpreted into 11 different domains and wireframes were created and geostatistical analysis was completed on the assay and 3m composite data for each of the metals.

The grades for copper and gold were interpolated into the block model using ordinary kriging, inverse distance squared and nearest neighbour method and the silver grades were interpolated using inverse distance squared and nearest neighbour method. The copper and gold tonnage and grade values were tabulated using the ordinary kriging interpolation results for the measured and indicated mineral resources and the inverse distance squared results were reported for the inferred mineral resources. Silver tonnage and grades were reported using the inverse distance method results.

Sherwood currently has two drills turning at Area 2 and Area 118, infill and step-out drilling in order to upgrade more of this inferred resource into the measured and indicated categories.

Area 118

Discovered in 2007, there was only one year's drilling at a relatively wide space available at Area 118 for resource estimation, thereby only an inferred mineral resource could be calculated. The inferred mineral resource estimate for the Area 118 deposit, using a 0.5% copper cut-off, is 6.59 million tonnes at a grade of 0.97% Cu, 0.27g/t Au and 3.07 g/t Ag for a contained metal total of 141.4 million pounds of copper and 60,000oz of gold and 650,000oz of silver. Area 118 is adjacent to, and contiguous with, the Area 2 deposit.

As tabulated at the end of this release, using a 1.0% copper cut-off grade, the Area 118 inferred mineral resource totals 2 million tonnes grading 1.6% copper, 0.5g/t gold and 5g/t silver.

Susan Lomas, P.Geo. of LGGC estimated the mineral resources for Area 118 in June, 2008. The estimate was completed in Gemcom Software (Gems) using a 3 dimensional block model (15m by 15m by 3m (vertical) block size). The mineralization was interpreted into 11 different domains and wireframes were created and geostatistical analysis was completed on the assay and 3m composite data for each of the metals.

The grades for copper and gold were interpolated into the block model using ordinary kriging, inverse distance squared and nearest neighbour method and the silver grades were interpolated using inverse distance squared and nearest neighbour method. The copper, gold and silver tonnage and grade values were tabulated using the inverse distance squared method results. The mineral resources in Area 118 were classified as inferred mineral resources due to the wide spaced drilling results currently supporting the estimate.

As mentioned earlier drills are currently turning at Area 118 and Area 2, conducting both infill and step out drilling. Sherwood aims to upgrade the confidence in these mineral resources before the end of 2008.

Ridgetop

As with Area 118, Ridgetop has only benefited from one year's relatively wide spaced drilling, resulting in an inferred mineral resource being estimated. The inferred mineral resource estimate for the Ridgetop deposit, using a 0.5% copper cut-off, is 4.89 million tonnes at a grade of 0.85% Cu, 0.23g/t Au and 2.0g/t Ag for a contained metal total of 92.1 million pounds of copper, 40,000oz of gold and 320,000oz of silver. Ridgetop is a very shallow resource, locally coming to surface beneath a few metres of overburden.

As tabulated at the end of this release, using a 1.0% copper cut-off grade, the Ridgetop inferred mineral resource totals 1.2 million tonnes grading 1.3% copper, 0.45g/t gold and 3g/t silver.

Susan Lomas, P.Geo. of LGGC estimated the mineral resources at Ridgetop in April, 2008. The estimate was completed in Gemcom Software (Gems) using a 3 dimensional block model (25m by 25m by 9m (vertical) block size). The mineralization was interpreted into 5 different domains and wireframes were created and geostatistical analysis was completed on the assay and 3m composite data for each of the metals.

The grades for copper, gold and silver were interpolated into the block model using inverse distance squared and nearest neighbour method. The copper, gold and silver tonnage and grade values were tabulated using the inverse distance squared method results. The mineral resources at Ridgetop were classified as inferred mineral resources due to the wide spaced drilling results currently supporting the estimate.

Infill drilling to increase the confidence in these mineral resources, plus further step out drilling to the east, will start at Ridgetop as soon as a drill becomes available from Area 118 / Area 2 and before the end of 2008.

There has been no adjustment to the Area 2 reserve from that announced on December 12, 2007, which was based on drilling to the end of 2007. See that news release for additional details on the basis for the reserve estimates and disclosure in respect of the Qualified Persons responsible for those estimates.

Minto Mine Reserve Reconciliation

To date, the block model to mine blast hole reconciliation has been positive with respect to the total copper metal mined. While the grade of the ore mined has been approximately similar to that projected in the block mode, on a bench-by-bench basis the total tonnes mined exceeded that predicted in the block model by approximately 20% in the second half of 2007.

To the end of 2007, 746,327 tonnes of ore grading 1.7% copper were mined from the Main Pit. In total, 238,446 tonnes of ore grading 2.16% copper were milled during 2007, leaving approximately 510,000 tonnes of ore grading 1.48% copper in surveyed stockpiles at December 31, 2007.

Despite mining of 746,327 tonnes of ore from the Minto Main deposit pit at a grade of 1.7% copper in 2006-07, the mineral reserve was reduced only by a net 325,000 tonnes at 0.89% copper. This smaller than projected net adjustment represents a significant gain in the reserve model from the last stated reserve estimate. This gain (as compared to that announced on December 12, 2007) is the result of a combination of factors including, but not limited to, additional diamond drilling within the pit limits since the last reserve estimate that increased the resource within the pit, possible gains in ore tonnages along the upper contact of the Minto Main deposit, and an optimised ultimate pit shell which brought some additional material into reserves.

Resource and Reserve Estimation Methodology

All mineral resources reported herein 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 mineral resource estimates. Mineral reserves were calculated by Minto Explorations Ltd geology and engineering staff under the supervision of Dan Russell, P. Eng. who is the Qualified Person under National Instrument 43-101 responsible for the mineral reserve estimate.

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® software for the reserve calculation. The mineral resource estimate was verified using MineSight® 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 and no dilution or recovery factors were employed. 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 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.

About Sherwood Copper

Sherwood'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 mineral resource and mineral 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 Ltd., 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.

The basis of and responsibility for the mineral reserve estimates for the Minto Main and Area 2 deposits as at the end of 2006 were detailed in the Technical Report for the Minto Pre-feasibility study, the results of which were announced on December 12, 2007. The update to the mineral reserve estimate for the Minto Main deposit and the reserve reconciliation were under the supervision of Dan Russell, P.Eng., Manager of Mining at the Minto Mine. Dan Russell is the Qualified Person under National Instrument 43-101 responsible for these estimates.

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.
