The more I read, the more Im set on copper mining stocks. The bigger China gets, the more the demand for copper is going to grow. Any idiot can look up the metals required to make a battery, but they seem to be ignoring the one metal they just cant do without. They arent going to make battery cables and switch contacts out of lithium, cobalt, nickel, etc. You cant make electric motor windings out of it either. You cant wind a windmill generator without it. Aluminum house wire was tried and they wont be pulling that crap again anytime soon. I also suspect there will be problems with pex plumbing as the years march on and it will be declared a failure as well. Copper demand is just going to keep rising, and the increse in mining isnt going to be able to keep up. You want to see a $100,000 GM/Ford/Chrysler electric mini-shitbox car ? Wait 10 years.
There are quite a few companies working on new ways to filter lithium out of salt water and I expect them to pull it off somewhere down the line. That will drop the price quite a bit. You dont need much of it for a battery and there are other metals being experimented with all the time. Copper mining and processing hasnt changed much in the past 50-100 years. Theyve got it figured out about as well as theyre going to and they're already cranking it out as fast as they can. Unless someone discovers some miracle copper mine AND theyre allowed to develop it, the only place the copper industry is going is up.
