To do SX-EW you need oxide ore - Near Mt Isa, EXS, URL and MRX have large holdings that include oxide copper ore in addition to the deeper copper sulphide ore. Hopefully Xstrata will buy up all these juniors while they are still grossly undervalued. The sum of the parts would be a massive tonnage with further discovery potential on their leases. These minnows don't have the capital to develop it and no single deposit seems big enough or high enough in grade on its own.
