NFG was hitting the beginnings of the systems at depts just 15 to 20 m.....that is shallow.
At Fosterville they worked that mine for 10 years until they hit the beginning of the system.
This was at 4000 to 5000 feet.
They were confused that is when QH told them to drill straight down.
So far they are 200m from that depth.
That is deep.
Please do not confuse the two and do not ridicule me because you do not know the
