Sherwood Finalizes Exploration Agreement with Northern Tiger Resources

VANCOUVER, BRITISH COLUMBIA (TSX VENTURE: SWC.DB) announced today that, further to its news release dated March 3, 2008, its wholly-owned subsidiary, Minto Explorations Ltd. ("MintoEx") has completed the sale to Northern Tiger Resources Inc. ("Northern Tiger") of a 100% interest in four properties located in the Dawson Range in the Yukon Territory and data sets comprised of a database of certain exploration reports, all in accordance with the terms of an acquisition agreement dated effective May 23, 2008 between MintoEx and Northern Tiger (the "Acquisition Agreement"). A copy of the Acquisition Agreement is available on SEDAR at www.sedar.com under Northern Tiger's profile.

"Through its transaction with Firestone Ventures, Sherwood Copper's subsidiary, Minto Explorations, has gained exposure to exploration opportunities outside of its Minto Mine property, having both (1) a back in right to any deposits discovered close to its existing mine infrastructure that could be processed at the existing process facilities and, (2) equity exposure to any other discoveries made through this alliance," said Stephen Quin, President & CEO of Sherwood Copper. "This is a win-win transaction for our respective shareholders and accelerates the exploration activity in the Minto Mine area and the Yukon, to a level beyond what Sherwood would do on its own. This will allow Sherwood exposure to more generative type opportunities but not detract from its main exploration focus on the more advanced and highly prospective Minto Property," he added.

As part of the transaction, MintoEx transferred to Northern Tiger a one hundred (100%) percent interest in four Dawson Range exploration properties and an extensive historical exploration database for the region. The four properties encompass exploration targets where previous prospecting encountered copper-gold mineralization similar to that hosting MintoEx's nearby Minto mine. In addition, Northern Tiger and MintoEx have entered into a Regional Exploration Alliance Agreement ("REAA"), which provides for input and cooperation on planning and executing exploration programs and long term strategies for the area, sharing of proprietary technical expertise to assist in exploration and project advancement, and access to MintoEx's infrastructure to facilitate exploration in the region.

As consideration for the transfer of the exploration properties, historical database and the support provided to Northern Tiger through the REAA, Northern Tiger has issued to MintoEx 4,343,878 class "A" common shares in the capital of Northern Tiger (the "Northern Tiger Shares") at a deemed price of $0.30 per share, such shares to be held in escrow pursuant to a TSX Venture Exchange Form 5D Value Security Escrow Agreement.

Sherwood's holding in Northern Tiger Resources Inc. will give its shareholders exposure to an exploration company focused on exploration targets generally located outside of, but in proximity to the Minto Mine property in central Yukon. In addition to its equity holdings in Northern Tiger, MintoEx would retain back-in rights to acquire a 65% interest in any of Northern Tiger's projects located within a 50 km radius that are found to have mineralization amenable to processing in MintoEx's existing Minto Mine facilities.

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.
