Copper has been printing record level prices around $13,000 per tonne lately, and the part that matters to me is not the headline spike but the stacked demand story.
EVs, robotics, defense tech, and AI data centers all pull copper at the same time. A common baseline is that a battery EV uses roughly 70-85 kg of copper versus about 20-25 kg in an ICE car, so it is a 3-4x intensity shift (industry estimates). Data centers are another sneaky driver because power distribution and cooling are copper heavy, and forecasts see a lot more data center load growth over the next decade (industry studies).
The supply side is the trap. New copper mines can take 10-15 years from discovery to production, and ore grades have trended down over time (industry reporting). That makes the market more sensitive to tight inventories and delays.
So where does RB fit? Rumble Resources (Canadian stock, ticker is $RB.CN) is not a producer, it is an early stage explorer. The bull case is optionality: if copper stays structurally tight, credible new targets and land positions get more attention from capital and potential partners. The bear case is also obvious: until drill results and resources exist, it is mostly a story plus a work plan, and explorers fund that with dilution.
If you were tracking RB as a copper optionality play, what would you want to see next?
I am also open for alternatives to diversify the copper play.
Not advice, read upon it yourself.
