Iran has confirmed the existence of high-purity lithium reserves in the country, the semi-official Fars news agency reported Wednesday.

The confirmation was made in a report by Iran's Ministry of Industry, Mine and Trade, following a one-year sample study on 46 stations in Iran's underground brine reservoirs in the provinces of Qom, Isfahan and Semnan, with advanced technologies, Fars said.

The samples were collected from wells dug with depths of up to 2 meters in Iran's salt pans, and then analyzed jointly by Iran Mineral Processing Research Center and a Russian lab, Fars said.

The study found that the highest purity level of lithium was found in samples taken from the Namak Lake in Qom, with 81.4 parts per million, Fars said.

Lithium is one of the key components in electric vehicle batteries.
