Matto,
The company has previously released a value estimate of $1251 per tonne. That was obviously the high grade resource. As Maxcap has previously stated the size of the resource could be 225Mt but lets use 125Mt to be conservative. Not all of that will be high grade so if we assume a resource value one quarter of that ($300) times 125Mt = $37.5 billion in ground value. What value should the company be? You decide.
