VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 17, 2011) - Cambridge House International's Silver Summit 2011 will again offer a limited number of underground tours of deep-shaft, working precious metal mines in the Silver Valley of northern Idaho. Tours will be conducted the morning of Wednesday, Oct. 19, a day prior to the two-day Silver Summit's official opening Thursday, Oct. 20 at the Davenport Hotel in Spokane, Wash.

Participating mines include Hecla Mining Co.'s Lucky Friday silver mine, U.S. Silver Corp.'s Galena Mine, and New Jersey Mining Co.'s Golden Chest mine. Transportation to and from the mines from the Davenport Hotel, along with breakfast and lunch, is included in the $135 cost of the tours. Mine tour proceeds benefit the non-profit Women in Mining Education Foundation.

"We are once again grateful to Hecla, U.S. Silver and New Jersey for taking time out of their busy production schedules to offer a few people a rare glimpse into the day-to-day operations of their complex and fascinating underground operations. This is a once-in-a-lifetime opportunity for the lay public to see how silver and gold are wrested from the earth and turned in to real money," said Shauna Hillman, Silver Summit Director.

Mine tour participants should be physically healthy, able to walk a kilometre in heavy boots, and must agree to comply with underground safety training instructions. The mines will supply necessary underground apparel.

Mine tours are being reserved on a "first come, first served" basis at the Silver Summit office in Wallace, Idaho, by calling 208.556.1621.
