..Wanderer5,,after thinking back to the conversation , i believe Gary was talking about extending the mine life at the Hart. Gary, explained that the ore was found ( to use as a comparison ) in , think of a rain storm with water on the road and you see small puddles on the road, well this is how they are finding the ore down below, through metalurical, they can follow the way the ore settled and locate these puddles,as long as they find the right type of ore . sorry about the explanation,,it made sense the way Gary explained it,.Traps7
