The Great Dyke of Zimbabwe, a 550-kilometre igneous intrusion running through the heart of the country, has long been celebrated as one of the world's premier platinum-group metal deposits. Exploration companies from Australia, Canada, China, and the United States are now pouring capital into the region in pursuit of lithium, the metal at the core of the global battery energy storage industry.
Zimbabwe already hosts what is believed to be Africa's largest known lithium reserve, centred on the Bikita deposit in Masvingo province. A series of new discoveries along the Great Dyke's northeastern extensions have expanded the prospective zone considerably, with preliminary resource estimates at several projects ranging from 50 million to over 200 million tonnes of lithium-bearing pegmatite.
The government of Zimbabwe has moved to position the country as a value-adding lithium hub rather than a raw ore exporter. A ban on unprocessed lithium exports, implemented in late 2022, has compelled investors to either invest in downstream processing within Zimbabwe or exit the market. Several projects have responded with commitments to establish spodumene concentration and lithium chemical refining capacity.
