Pegmatites:

The largest known lithium-containing pegmatites occur in the vicinity of Manono. Each of a pair has a length of 5,000 metres and a width of approximately 400 metres. The weathered zone has been worked for tin and columbite .

Assuming a depth of only 50 metres the pegmatites could contain 2.3 million tonnes of Li.
