About forecast resource exploration and staging (solid economic minerals)

Analyzes the existing inconsistencies between categorical Stu-staging and prognostic resources exploration. Is invited to carry out updating the «Regulations on the procedure for geological exploration work in stages and phases (solid minerals)» and «Classification of reserves and inferred resources of solid mineral fossil», aimed at better harmonization of the staged exploration and inferred resources, implemented on each stage. Proposed updated definition of the inferred resources category P₃, P₂, P₁. Projected reserves of different categories should be assessed in amounts corresponding to the expected reserves of C₂ category.
Key words: inferred resources, categories of P₃, P₂, P₁, C₂ category reserves, exploration staging.
