Aplicación comparativa de estimación de recursos minerales entre el método clásico y el método geoestadístico, para un manto polimetálico en un Skarn ubicado en el norte del Perú

Abstract

In every mining project, the less level of knowledge, the greater the uncertainty level of the mining deposit can be. And it will be significantly present in the geoeconomically evaluation of its mineral resources. These days the estimated mining resources have a great deal of methods for every kind of deposit that can be adjusted to the geological interpretation of the structure or body that comprises economical mineralizing.

This professional sufficiency work paper has the mining resources estimation from a subvertical polymetallic mantle as a goal. Using unitary block as a model and contrasting it with a traditional estimation method afterwards. To achieve this, historical data from already drilled probes holes in situ will be gathered. Following this, there will be a M3T model of the mantle made with geological software and with statistical methods (Ordinary Kriging, close neighborhood and inverse distance) the block unit of the mining body will be estimated.

The fundamental support and estimate of this whole process relays in the analytic and quantitative treatment reports from the average mill head grade during the M3T mining, compared with the results estimate of the extracted mineral sampling. Which finally has given the highest reliability to the applied method, as it is show in the discussion and interpretation of results.
