Silverstone Completes Purchase of Life of Mine Gold and Silver From Sherwood Copper Corporation's Minto Mine

VANCOUVER, BRITISH COLUMBIA, Nov 21, 2008 (MARKET WIRE via COMTEX) -- Silverstone Resources Corp. ("Silverstone") (CA:SST) is pleased to announce that it has closed its previously announced transaction (November 7, 2008) with Sherwood Copper Corporation to purchase all of the payable gold and silver from the Minto Mine in the Yukon, Canada, over the life of the mine starting December 1, 2008.

Silverstone will purchase all of the payable gold and silver from the Minto Mine and, in exchange, Sherwood received an up-front payment from Silverstone of US$37.5 million, plus a further payment of the lesser of (a) US$300 per ounce of gold and US$3.90 per ounce of silver (subject to a 1% inflationary adjustment after three years and each year thereafter) and (b) the prevailing market price of gold and silver quoted on the London Bullion Market Association, for each ounce delivered. If production from the Minto Mine exceeds 50,000 oz of payable gold in the first two years of the agreement or 30,000 oz of payable gold per year thereafter, Silverstone will be entitled to purchase only 50% of the amount in excess of those thresholds. Kutcho Copper Corp., Sherwood's wholly owned subsidiary that owns the Kutcho copper-zinc-silver-gold project in British Columbia, has also granted Silverstone a right of first refusal to purchase any gold and/or silver streams from the Kutcho project, should Kutcho Copper elect to sell such, on terms and conditions to be agreed by mutual consent. Sherwood and Silverstone have now signed definitive purchase agreements with respect to the above described transaction.

In order to fund the US$37.5 million cash payment, in addition to US$28 million in cash on hand, Silverstone has drawn on its US$15 million revolving line of credit through Scotia Capital.

"Silverstone is very pleased to add the Minto Mine gold and silver production which more than doubles silver equivalent production in 2009 to 4.5 million ounces of silver(1). This transaction provides leverage to both gold and silver," said Darren Pylot, President and CEO of Silverstone Resources Corp.
