RE:Copper $4.62 /lb
these are pipes they are drilling. It's not like these grades are bulk tonnage. If you get directly over the pipe & drill down the dip you get galactic results, but it is confined. When I first read about Chakana's drill results, I was stunned also. But this will be an underground mine taking out the juicy pipes, so it is technically more difficult & expensive than open pit. If this were open pit bulk tonnage I would agree with SP in the dollars, but its not.
