Platinum minerals were also studied in the low-sulfide mineralization of the Nomgon troctolite-anorthosite-gabbro massif ( Izokh et al., 1992 ), but commercial deposits have not been found yet. Such deposits are confined...

...A.V. Kutyrev; E.G. Sidorov; A.V. Antonov; V.M. Chubarov Abstract In the alluvial deposits of the Prizhlimny Creek (southern part of the Koryak Highland), grains of platinum-group minerals are found along with gold. We have established that the grains are native platinum (Pt, Fe) containing Cu (up...

Hence, this interface requires further verification...
