The main types of waste from mining and metallurgical production, used for backfilling of pits and mines, backfilling of tailings dams, road ballasting, in the production of building materials, crushed stone, for the re-extraction of various components, are considered. A brief description of the Gaisky Mining and Processing Combine as an independent technogenic deposit and information on the percentage content of useful components in the accumulated wastes are given. A methodology for systematic environmental and economic cadastral evaluation of secondary mineral resources is proposed. It is proposed to evaluate secondary mineral resources from the position of the national economy (national-economic assessment) and from the position of commercial interests of the enterprise (commercial assessment). The criterion indicator, in our opinion, should be the economic effect on the national economy.
