Anyway, I sure hope we don't see any sort of repeat of those events in 2021. 

Good to hear you chime in YourNadir.   I really doubt it.  The supply-demand outlook is way stronger for higher and sustained copper prices.  The electrification of the world is upon us in a way that did not really exist 10 years ago. Extremely low inventories. China's economy (@6.5% /yr GDP) would be twice as large since then. Declining grades. No major CU deposit discoveries in the last decade.  ahhh, you've heard it all before no doubt, LOL.  But it seems like all these catalysts are lot more in our face than before.

And we're on the cusp of the 'roaring 20's' economy, imo, with a growing flood of injected helicoptor money into the world economy.  

Good times ahead, mate!
