Pebble is not too good to be true. It has been carefully appraised by experts.
Does ZTEM tell us we have 6 or 7 equivalents to Pebble?
Signal, yes. But what about actual value?
Does ZTEM tell us we have the same quantity, mix, and grade of ore?
Or does ZTEM tell us only that we have good readings and must drill to find out about quantity, mix, and grade?
That's a key question. I don't know enough to answer it.
