Correlation Analysis of the Relationship Between Mineralogical Composition and Copper Content at the Bozshakol Deposit

This survey presents a comprehensive investigation of the ore component content in rocks and its relationship with the mineralogical composition. The aim of the research was to identify patterns in the distribution of ore elements, particularly copper, depending on the composition of primary and secondary minerals. The work is based on an integrated analysis involving both petrographic and mineralogical research methods. As part of the study, a detailed examination of rock samples taken from borehole core was carried out. Particular attention was given to the microscopic analysis of thin sections, which made it possible to determine the textural and structural features of the rocks and perform a quantitative assessment of the content of primary and secondary minerals. To improve accuracy, geochemical analysis methods were used to refine the content of ore components and determine the percentage of various minerals in the rocks. The results showed that copper content can vary significantly depending on the degree and type of secondary alteration, as well as the presence of specific minerals such as chalcopyrite, secondary quartz, chlorite, and sericite. To identify and quantitatively assess the relationships between copper content and mineralogical composition, Pearson’s correlation coefficient was applied. This made it possible to establish statistically significant correlations between certain minerals and copper concentration. Positive correlations between copper content and specific minerals were identified, as well as negative correlations with minerals formed during intense alteration processes. The obtained results have practical significance for geological exploration. The revealed correlation relationships can be used during core description and in the development of predictive models of ore-bearing potential, which significantly increases the efficiency of exploration work. The methodology applied in this research can also be adapted for other deposits with similar mineralization conditions.
