Bavsiite is a relatively new mineral, approved in 2014 and to date (January 2025) confirmed only at the type
locality.
Localities
At the type locality, the Gun claim, Wilson Lake, Itsi Mountain, Watson Lake mining district, Yukon, Canada,
bavsiite occurs as millimetre-sized sky-blue platy crystals in a
barium-rich low-temperature skarn
related to a porphyritic quartz
monzonite stock. Associated minerals are
alstonite, baryte,
celsian, diopside,
fresnoite, mica,
suzukiite, walstromite,
witherite and minerals of the
cerchiaraite group
(MM 83.6.821-827).
