To quote Sculpins own numbers if they are accurate.
" If I remember correctly, our highest grade copper was around 0.13 %, at the time, with the price of copper slightly higher than it is today economical copper needed to be at least 0.12 %."
If these numbers are correct that would give you 1,179 g of copper per ton.
.0013 x 907,184.74 (number of grams in a ton) = 1,179
If 1 g/t of gold (as some are doing math with) is supposed to show up on Quantec as a magnetic anomaly don't you think 1,179 g/t of copper would leave an image?
The guy had a fair question that should be answered. If Sculpin is saying we may have 0.13% of copper that is a lot more copper in the ground than gold as one would expect to show an image on Quantec.
