Looks like another company has decided that the old mining areas in Owyhee county are worth examining. BTW, this company (SHSH) is a favorites of Rocketstocks- wonder what he'll say about their judgment now? Here's the PR- bolding added:

COEUR D'ALENE, Idaho, Aug. 15, 2012 /PRNewswire/ -- Shoshone Silver/Gold Mining Company (SHSH) (SHSH) announced today that it has entered into a 90-day due diligence option with Silver Leaf Exploration to lease 54 unpatented claims in Owyhee County, Idaho which comprise almost all of the historic Flint Mining District. Shoshone has paid Silver Leaf $15,000 as an option payment and will cover the BLM filing costs on the unpatented claims which are due by the end of August.
"We are very excited about this opportunity for Shoshone," stated Howard Crosby, Shoshone's president. "The Flint District has not been explored in any significant way for nearly 100 years, and we believe there is excellent potential for high grade silver and gold deposits analogous to the Silver City/Delamar District some 20 miles to the north," said Crosby.
No serious exploration or development in the Flint District has occurred since the early 1920's, and many of the exposed veins are unexplored both along strike and down dip. After exercising its option, Shoshone plans to conduct detailed surface mapping of the veins, conduct a geophysical survey of the claims, and develop drill targets to test the downward extension of the veins.
