They talk of enormous pits like at Fort MacMurray. With HUGE equipment. Definitely a long term project that can only be financed eventually by DeBeers or Rio or BHP. If you are interested and have not already, check into Stikine Gold .. V.SKY. They are exploring a mineral target that starts 8000 feet below surface where temperatures are close to 70 degrees C. Now THOSE are problems. The argument the hypsters use on that one is .. if it's good enough, technology will figure a way to mine it. They never say never. Hey .. I'm just a spectator .. don't hack at me about knowing the value of stones or mining problems. I yam what I yam. The Gumper. LOL.
