426 2.2.2 Spatial and Geometric Characterization Figure 2 – Spatial Maps of weighted heap height (H weighted). The spatial distribution of weighted heap height reveals structured growth patterns, with clear zones of progressive elevation. These maps demonstrate structured heap growth and preferential discharge zones. 2.2.3 Metallurgical Interactions Efficiency analysis against a competition ratio indicator suggests that chemical interaction effects influence short and long-term recovery behavior. 3. RESULTS Linear regression with engineered features model was evaluated using time-based splits to preserve temporal causality. Spatial heat maps represent model-attributed production/recovery based on block-level placement and the reconstructed heap-state response, not direct per-block measurements. All quantitative values are withheld for confidentiality. Figure 3 –Predicted Au vs Actual Au Scatter Plot using linear regression with engineered features model. During the training period, the model explained approximately 64% of the variance in monthly gold production (R² = 0.64). When evaluated on unseen validation and testing periods, the model maintained predictive capability, achieving R² values of 0.38 and 0.37 respectively. The relatively moderate decrease from training to validation indicates limited overfitting and acceptable generalization capacity. 0 0.2 0.4 0.6 0.8 1 0 0.2 0.4 0.6 0.8 1 Predicted Au Actual Au
