"When you read it carefully, that statement is ambiguous.An interval has a start point and end point. We know the end point – it is 769m.But what is the start point? is it 769-250= 519 m (a 250m interval) or is it from 250m to 769m (a 519m interval).That is a big difference."
DDH 2012CF427 located 400m north of DDH 2012CF426 with a core length of 769.3m intersected visible copper +/- molybdenite mineralization from a core interval of 250.0m to the end of the drill hole at 769.9m. The chalcopyrite+/-molybdenite mineralization is open at depth,
The core interval starts at 250.0 metres and ends at 769.9 metres.
