What if flooding shuts Alaska's Red Dog zinc mine?
Flooding and a permit fight shutting Alaska's Red Dog removes a major slice of Western zinc concentrate — the direct move is zinc and zinc-miner equities higher on the concentrate hit; the lone Freeport copper link is a generic beta stand-in. Rhymes with periodic Red Dog weather/shipping-window disruptions and the 2018 zinc squeeze on low LME stocks. Forward angle: Red Dog is ~5% of global mined zinc and a key non-China concentrate source, so a closure tightens treatment charges and Western smelter feed specifically — zinc TC/RCs and the LME spread are the cleaner expression than copper.

What it would mean
If this plays out, it is a mixed shock. Flooding and a permit fight shut Alaska's Red Dog, removing a major share of Western concentrate supply. The trigger decomposes into signed root‑shocks — Industrial demand ▲ — which propagate through our causal graph to the markets below.
