opinionI suspect that more people will be looking at this discussion. Always keep in mind that the actual drill results will do the talking. That said, what we know is that Amarc/Freeport is hunting for a large AU/AG/CU porphyry at JOY and Amarc/Boliden for a similar porphyry at DUKE which are economical.
What is large and economical? A 2 billion tonne mineralized ore porphyry with .8% CUEQ example would do the trick. After metallurgy/recovery rate we would have $100CAN rock in each tonne. Meaning $200B CAN. in the ground. Thats what they are looking for.
Note that grades of .6% CUEQ is still fantastic and 1% CUEQ would be a dream come true. GLTA
