Heavy mass of arsenides and it's hard to discern them without the aid of an EDS and XRD. Mostly though seems to be some brassy Nickeline and whiteish gray Domeykite. It's a good specimen as large as it is and green and blue alterations.

This specimen is from Dr. Igor Pekov's study material.
Virtually all of the bright green crystalline areas on this specimen is Ericlaxmanite. Very few of these specimens were collected by the team of geologists from Russia including Dmitriy Belakovskiy and Igor Pekov. The team took fascinating videos while collecting on and in the scoria cone vents under extremely hot and toxic conditions. The remoteness and altitude alone are enough of an obstacle to keep most serious collectors away from this place. Type material is deposited at the Fersman Museum in Moscow and the new mineral was published in Mineralogical Magazine 77, 2695-2709.
Specifically the correct locality is: Arsenatnaya fumarole of the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka Peninsula, Far-Eastern Region, Russia.
