445 Figure 20. Descriptive statistics of minerals and elements by grinding cluster in Phase I. Description: ● HORNFELS: Predominant in Cluster 3 (Median = 21.98%). ● INTRUSIVE A (INTRUSIVOA): Predominant in Cluster 2 (Median = 41.77%). ● SERPENTINIZED SKARN (SKARNSERPEN): Predominant in Cluster 1 (Median = 26.56%). ● PYRITE (PY): Highest proportion in Cluster 1 (Median = 8.68%). ● CHLORITE (CHLOR): Greater presence in Cluster 1 (Median = 5.75%). ● MAGNESIUM OXIDE (MgO): Predominant in Cluster 1 (Median = 9.55%). ● IRON (Fe): Predominant in Cluster 1 (Median = 10.57%). ● BOND WORK INDEX (BOND): Highest value in Cluster 1 (Median = 13.87%). ● DROP WEIGHT INDEX (DWI): Highest value in Cluster 1 (Median = 7.08%). ● HARDNESS (HARD): Highest value in Cluster 2 (Median = 2.83%). ● MICKLEY INDEX OF COMMINUTION (MIC): Highest value in Cluster 1 (Median = 7.57%). ● BLASTABILITY INDEX (BI): Predominant in Cluster 2 (Median = 16.08%). 4.1.1. Analysis of operational behavior by cluster A temporal evolution analysis of the clusters was conducted, revealing periods of continuity and stability over time, where the same cluster remains active for extended intervals. This behavior demonstrates that the clusters identified in Phase I represent persistent mineral and process patterns rather than random variations, and that transitions between clusters are driven by real changes in the characteristics of the fed ore and operating conditions. Table 1 – Distribution of clusters in milling Phase I, from January to December 2025 Cluster Data quantity Occurrence Cluster 0 648 10.9% Cluster 1 193 3.3% Cluster 2 1664 28.0% Cluster 3 434 57.8% A temporal distribution analysis of each cluster occurrence throughout the year was performed, identifying the relative frequency of appearance of each cluster. This analysis allowed the evaluation of cluster representativeness and persistence over time, as well as their contribution to the overall behavior of the grinding circuit.
