RE:From Katusa Research, projected copper demand and price incr https://pebblewatch.com/wp-content/uploads/2020/09/PW-MineralResourceIndependence-Sept2020.pdf
That's all fine and dandy, but has nothing to do with this project.
Concentrate from the current proposal will be shipped to "Asian" refineries per the proponent of which China are the largest facilities. The metals will not enter US or Canadian manufacturing unless purchased from Asian/Chinese refineries. Unlikely since they will be consumed in overseas manufacturing.
No strategic benefit for the US or Canada.
