CARMACKS COPPER-GOLD BELT
The Minto Mine
The Minto Mine is a high grade copper-gold operation situated 240 km north of Whitehorse, Yukon with mill commissioning currently underway. It is owned 100% by Minto Explorations Ltd., a wholly owned subsidiary of Sherwood Copper Corporation. The Minto Mine is an open pit mining operation with conventional crushing, grinding, and flotation circuits which produce copper concentrates with significant gold and silver credits. Concentrates are to be exported via the port of Skagway, Alaska, to smelters in Asia for treatment and sale. Mine production is forecast to ramp up to full capacity during the third quarter of 2007.
Sherwood acquired the Minto Property and all other project interests in June 2005. Within two years from acquisition, Sherwood has upgraded the geological resources to reserve standards, completed a bankable feasibility study, arranged project financing, built a new mine which is currently being commissioned, and staffed it for production.
Access to Minto is via the Klondike highway to Minto Landing, where boat, barge or ice-bridge gives access across the Yukon River to the head of an all-weather, production standard gravel road constructed to the site.

The Main Zone contains a higher grade core and is the primary focus for planned mining operations, while the Other Zones are satellite mineralized zones located above and below the Main Zone, the shallower of which are partially to fully oxidized and will be stockpiled for possible later processing. Mineral Resources at different cut-off grades are summarized below and detailed in the attached table.

Reported July 10, 2006
Mining will be focused on the high grade core of proven and probable reserves of 5.9 million tonnes grading 2.20% Cu, 0.80g/t gold and 9.1g/t silver. The grade averages for the first six years of production will be 2.4% Cu and 0.89g/t gold yielding 41m lbs Cu and 17,295 oz gold per year.
