There are actually several points.
You've heard the number of 10 years from commencement to development to bring up any mine-particular errors in production. In actual fact, Strange Lake has a much longer history than that. The original discovery in the area was made in the late 1970s. At that time, quite a bit of metallurgical research, which is obviously the critical path for these developments, that is, the processes required to separate the rare earths from the rock, had been ongoing over that period. We actually were able to piggyback off a lot of that technical work that had been done prior to ours.
