Thanks as this is the detail that I remember seeing earlier.

While Sudbury might not be a match for this deposit it is good to remember that some of these deposits are deep underground and not yet drilled to test since so much rich ore lies close to surface and easily extracted.

No one has really estimated the potential IF someone hits a large rich source for the closer to surface deposits. Who ever finds something like that will become 'King of the Hill' and add billions not millions to their share price.
