N2 - The high stability of radiogenic He in natural conductive nonmetals is firstly shown for the example of sperrylite (PtAs2). The urgency of its study is explained by the abundance of Pt sulfarsenides, in particular, sperrilite in many PGE deposits. The Pt-190-He-4 age of sperrylite from the famous Kondyor (AyanMaya region) and Oktyabrsky (Norilsk region) PGE deposits was determined for the first time: 122 +/- 6 and 242 +/- 12 Ma, respectively.
