reports shares in Vane Minerals  jumped by over 17% after it revealed higher grade gold/silver production as a result of the joint venture formed with the Ruiz Brothers in June last year.  The results are the first that report the recovery progress from switching feedstock from solely Vane's wholly-owned Diablito mine to combining areas owned and mined by Ruiz. Headed by the ex-head of exploration at Freeport-McMoRan, Steven Van Nort, Vane also has gold and copper exploration projects in Mexico and Paraguay and uranium assets in Utah and Arizona.
