There is plenty of gold... Pretium video from 2011 9 years old excellent Pretium video. Only 3 minutes long and it shows many of our options for the nearer time future.
I encourge you to use at certain sequences the stop function to understand the all the view twists and to read all the text and figures. Special interest is at around 2`30``... and of course always at "Snowfield".
Enjoy and keep eyes on our unique long term investment reward !
Hopefully O'Brien & Perron will know this 2011 video and all the underlying datas for it as well...
