By Charlotte McLeod  What comes after a once-in-a-lifetime gold discovery? According to Mark Selby, president and CEO of RNC Minerals (TSX:RNX), the work has just begun. Earlier this month, Selby’s company shook the gold space with the announcement that it had unearthed over 9,000 ounces of gold from a space the size of a living room. The discovery, made at RNC’s Beta Hunt mine in Western Australia, was later boosted to 24,000 ounces of gold worth $38 million.
