Murundu mine is a sub-horizontal zoned pegmatite, about 15 m thick; it was mined until 2006, having produced outstanding clear quartz crystals (colorless, smoky or citrines), normally showing "cathedral" shape, measuring up to 30 cm, associated with round-shaped clusters of yellow to yellowish-green muscovite crystals; both the quartz and the muscovite were often partially coated by brown to pinkish-brown zanazziite crystals measuring up to 3 mm.

The mine is actually closed and flooded; in 2010 one specimen was recovered from the dumps of the mine containing tabular brown twinned lithiotantite crystals measuring up to 3 mm, associated with massive reddish-brown wodginite, over a milky quartz matrix. It allowed the description of the crystal structure of lithiotantite (Menezes Filho et al., 2012).
