Abstract - Summary 
(short description):
Grains of maldonite were isolated by dissolving in hydrofluoric and nitric acids from samples of the Early Cretaceous gold - rare-metal ores of the Front and Kunkuy occurrences . Besides microinclusions maldonite in native gold were identified three varieties: a ) a very small independent grain ; b ) maldonite grains fragmentary coated with a thin shell of high-fineness native gold; c) grains of maldonite in the intergrowth (in various proportions ) with very high-fineness native gold eloquently - looped (or eloquently- spongy) texture with bismuth oxide . Were found that in the early stages of the ore formation of Front occurrence grains of maldonite accounted for approximately 25% of the total number of selections maldonite and native gold; Kunkuy occurrence - about 45%.
Keywords: ore occurrence, gold and rare metal mineralization, maldonite
