Good to see Zinc prices heading back up. I've got a theory (only a theory) about the rout in certain commodities (copper & zinc particularly) which is that China has started to buy cheaply and quietly directly from Russia who has mega tonnes of ore and all the gas they need to run their smelters day and night which is why they can supply zinc back to the LME (probably making a profit there too). See https://www.reuters.com/markets/commodities/tight-lme-zinc-inventories-could-be-topped-up-china-2022-06-22/ if this is the case, which a power like the US would know, it means that spot prices won't have too much of an impact at all on the EXIM decision.
