An offtake agreement is a long-term commercial contract between a mining company and a buyer, such as a smelter, refiner, trading house, or end-user, under which the buyer commits to purchasing a specified portion or percentage of the mine's future production, often before that production has even begun. Offtake agreements are particularly significant in bauxite, gold, iron ore, and diamond mining because they provide revenue certainty that can be used to secure project financing from banks or investors, who view a signed offtake as evidence of a guaranteed market for the commodity. Terms typically specify the volume or percentage of output to be purchased, pricing mechanisms (which may be fixed, market-linked, or based on a formula referencing benchmark prices), quality specifications, delivery logistics, and the duration of the commitment, which can range from a few years to the life of the mine. In iron ore and bauxite, offtake agreements often tie producers to specific smelters or refineries with particular processing requirements, while in gold and diamonds they may involve streaming or royalty financing structures layered alongside the offtake. These agreements reduce market risk for producers but can also limit flexibility to sell into spot markets if prices rise unexpectedly.
