Copper decline in new mines, page-3

I know there are a lot of people invested here for the cobalt, but for me it is the copper for all the reasons you have posted Speccy.
For me the real clincher in how copper would be in demand in the future is the amount of money BHP and RIO are spending on their joint venture, the Resolution Mine in the US that is from 1300m to 2600m deep. It is very big money they are spending to get to that copper, that tells me they are finding copper elephants much more difficult to find..
Finding info like this......"Rio is working with manufacturers including Caterpillar Inc. and Komatsu Mining Corp. to build battery-powered electric loaders and other equipment than can operate in the mine’s underground tunnels.", just reinforces how rare and valuable the big companies think copper is. That is a lot of extra expense right there (plus another use for battery minerals).

This part from the Mining Intelligence article surprised me.........
"Operating mines currently have an average grade of 0.53% while copper projects under development have an average grade of 0.39%."

I thought I had read elsewhere that average copper grades had fallen to .6% on existing mines, but .53% is getting really low. I do however wonder if that is just the copper component with other metals bringing up the 'copper equivalent' percentage. Copper is usually associated with Gold, Silver, Zinc or Molybdenite. I don't know of any just Copper mines.

I am invested in several copper juniors, AML easily have the highest grade, especially after by-product credits, and the cobalt here is a BIG credit, but even when cobalt comes down again in price, I still see a long future for mining at Walford Creek. Looking forward to the assay results for the western areas with enthusiasm.
