The present research work proposes to determine the acceptable range of variability in the measurement system of the copper and gold contents in the concentrate, between the storage warehouse in port and the point of dispatch in the mine, by carrying out a series of analysis of variables within the study process at the level of sampling, sample preparation, laboratory analysis and statistical methods used, with the determination to determine if the economic impact for the company is significant. For which the economic analysis of the mining sector at national and international level has been described. This is where the importance of the differences in copper and gold content between the dispatch and storage points of a mining unit comes from. In other words, if the acceptable variables or ranges of the copper and gold differences are not identified, the real economic impact on the company cannot be determined. The present work has used the Anova statistical method and the hypothesis T tests, as well as analysis of the measurement system MSA (Measurement System Analysis) using Gage R&R, which has allowed us to determine that the measurement systems in both places (mine and storage warehouse) have to improve through the standardization of processes: sampling procedures, operator training, implementation and calibration of similar equipment, weekly balances between both points. This allows us to decrease the variability between copper and gold results both in the mine and in the storage warehouse.
