APPRAISAL PROCEDURE FOR PROBABLE RESOURCES OF MININGGENERATED PLACERS IN YAKUTIA

Degradation of mineral quality in placers in the Republic of Sakha (Yakutia) enhances interest in gold production from waste or mining-generated placers. The review of methodological literature shows that the best promising approach to the appraisal of resources contained in the mining-generated placers is the method based on the analysis of loss of the primary production. Considering geology, technology and field data, the procedure is proposed to evaluate probable gold resources in mining-generated placers. The procedure is based on the methods of Irgiredmet, VNII-1, author’s procedures by G.S. Mirzekhanov, A.P. Van-Van-E and V.V. Chemezov. The analysis program is developed, as well as the values of influencing factors and their interaction are estimated using statistics and theory of multiple factor experiment. The criteria (factors) are selected for application in the proposed procedure. The values of the factors are determined and refined with regard to conditions of placers in Yakutia. The formula of cumulative probable resources of mininggenerated placers is offered. Probable resources are calculated for some specific mining-generated placers. The feature of the proposed procedure is the conformity factor of washing technology, factor of frozen condition of rocks, sluicing factor and morphology factor characterizing flattening of gold particles.
