Mine Reconciliation Standardisation - R Factor Series: A Case Study from Torex Gold Mine, Mexico

Explore a comprehensive presentation on mine reconciliation standardization, focusing on the R Factor Series, delivered by Rayleen Hargreaves at the Datamine Software Geology Symposium. Delve into the fundamentals of mining reconciliation, the F Series Framework, and the extended R Series Framework. Examine a detailed case study from Torex Gold Mine in Mexico, showcasing practical applications of these reconciliation methods. Gain insights into resource and reserve models, mine planning, grade control, and data management across various mining stages. Learn how to implement and interpret R Series factors, including R1 (Reserve/Resource), R2 (Mine production/Resource model), and R3 (Plant feed/Resource model). Discover how these standardized reconciliation practices can improve operational efficiency, enhance reporting accuracy, and potentially save millions in proactive planning.
