  • Region
    Susumansky district of Magadan region
  • Year
    2017
  • Type
    Assessment of ore gold deposits
  • Survey of geological-structural, morphological, and parametric characteristics of the ore zones Main and South
  • Study of material composition and distribution of ore mineralization, character of metamorphous and metasomatic changes in enclosing rocks, physical properties of ores and ore-hosting rocks
  • Assessment of technological properties of the ores
  • Survey of hydrogeological, engineering-geological and ecological features of the work performance site
  • Elaboration of feasibility studies for exploration conditions, estimation of the ore gold deposits by categories C1, C2 in the ore zones Main and South
  • Reassessment of P1 category forecast resources on the flanks of the ore zones
  • Development of recommendations on the further performance of geological prospecting and exploration
  • The project was implemented in accordance with approved technical (geological) specifications and calendar schedule of geological prospecting and exploration
  • The engineering studies of the ores revealed the low levels of sorption cyanidation in enrichment products, and, therefore, it was decided to carry out the work on autoclave processing of gold ore concentrates
  • The autoclave processing was preceded by an additional re-cleaning enabled to increase the gold content in the flotation concentrate by 62%, and by a test experience on flotation using a depressor reagent, which allowed to reduce the mass share of carbon substance in the re-cleaning concentrate in 5 times and increase the quality of the concentrate in terms of the gold content by 35%
