I was privy to the Russian lift that worked out of Prince George and there is no way equipment like that was transported or hidden in some tunnel. Look up the weight between a D8 and the machinery you are talking about. It doesn't work. It's over 100 times the amount and no helio can carry it. I always agreed with you Prospekt, but you are wrong on this. You might fly a little Cat or something in there to make level ground or a camp road but no chance on ore trucks or anything else hidden in tunnels.
