metadata.value: A wide mineral scattering halo of fine and thin high-standard gold with still unidentified commercial
  placers and primary sources is typical for the East Siberian platform, particularly the
  central part of the Viluy syneclise. It is related to the fact that the studied area overlaps with
  a thick layer of the Mesozoic-Cenozoic deposits, where traditional methods of prospecting for
  gold deposits do not yield positive results. It is well known that placer gold can retain “genetic
  memory” of its primary endogenetic gold sources. In this connection, detailed mineralogical
  studies of placer gold were performed with the aim to identify mineral types of gold mineralization
  and to forecast and assess primary gold content. Mineralogical-geochemical features
  of gold and mechanisms of its distribution from channel fill and the Quaternary deposits of
  numerous water courses of the Lena-Viluy interfluve. Over 300 samples were analysed, and
  the analysis takes morphologic features of gold, granulometric composition, fineness, composition
  of trace elements, inner structure and presence of micromineral inclusions into account.
  Permanent admixtures of Pt (6–96 g/t), Pd (5–570 g/t) and Ni (5–100 g/t), as well as micro-inclusions
  of the exotic mineral phase of platinum group are identified in placer gold of the Suntar
  arch in right-bank tributaries of the Viluy river (Kempenday, Chybyda, Tonguo, Kundayi
  rivers etc.). Apart from that, micro-inclusions of hematite, ilmenite, rutile, sulfides (pyrite,
  chalcopyrite, galena) and Fe—Mg-aluminisilicates, which correspond to ore mineralization
  and are typical for magmatism of the basic composition, are found in gold. The combination
  of identified mineralogical-geochemical features of gold indicates that the Precambrian hightemperature,
  deep depth mineralization processes were primary sources of gold. This allowed
  to forecast the presence of primary sources of gold-platinoid mineralization, probably related
  to basites of the Early Proterozoic and later age, within the Suntar arch for the first time.
