> Potássio do Brasil, controlled by Canada's Brazil Potash, says it needs to raise US$2.8 billion to build an underground potash mine in Autazes, Amazonas, with construction taking four and a half years after funding is secured. CEO Matthew Simpson made the announcement at a Brasília seminar on November 11, 2026, citing a price swing from US$300 to US$1,200 per tonne over five years.

A domestic Brazilian potash mine would reduce the country's dependence on imported fertilizer over the long run, but it offers no near-term supply relief. Brazil's heavy reliance on imports keeps potash prices exposed to global supply swings.
