Abstract
Modern large-scale mineral extraction demands a responsible approach to subsoil resources, prioritizing the minimization of ore losses and dilution. High loss levels typically occur at the contact zones between ore bodies and host rock due to discrepancies between mining contours and geological boundaries. This article addresses the standardization of losses and dilution specifically within these near-contact developments. The research proposes a specialized method for calculating standard values within stochastic zones. Investigations established a direct correlation between the geometric form of the contact and the resulting levels of ore loss and dilution. By applying the methodology developed in this study, mining operations can determine standard loss values at contacts with greater simplicity and reliability. This approach provides a scientific basis for enhancing the economic efficiency and sustainability of the mining complex
