Fairly rich specimen with dozens of hemispherical groups of light yellow Calcioferrite. Calcioferrite is a rare mineral found in about a dozen or so pegmaties and/or phosphorite (sed-meta) deposits worldwide. This locality is a phosphate quarry which is home to five type locality species and and several other rare phophates.
Excellent rich specimen which looks a lot like Montgomeryite. I acquired the specimen from Vince Peisley, an expert at the locality.

Calciojohillerite is a greenish to yellowish to almost colorless well-shaped, terminated crystals (about 1 mm) combined in clusters / crusts on basalt scoria altered by fumarolic gas. The specimen is very rich. It is one of the few study specimens from Igor Pekov's collection used to characterize the new mineral. It is not yet published but was approved in 2016.
A more detailed locality is: Arsenatnaya fumarole, Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka, Russia.
