Webinar: Mine Reconciliation Standardisation - R Factor Series

Please join us for this complimentary webinar in the lead up to AusIMM's International Mining Geology 2022 Conference.

About this event

This webinar presents a structural extension to the reconciliation process, wherein resource ratios (R Series factors) are used to quantify the long-term impact of the information effect, together with dilution and ore loss. A case study from the El Limón Guajes (ELG) Mine Complex in Mexico is used to demonstrate how an R Factor Series can be implemented to facilitate operation optimisation, over and above conventional F Series reconciliation treatments. This approach is applicable to any mining operation.

Whereas mine reconciliation is a well-established month-end process for most modern mining operations, the resource sector has yet to endorse uniform reporting factors against which model accuracy and metal recovery can be formally assessed. Logically, any comprehensive reconciliation framework should facilitate comparison between period reserve, mine and mill and production figures. Historically, Parker’s F Series ratios (Parker, 2012) are often used in some form by mine operators, although they are rarely shared externally, as formal definitions have yet to be accepted.

Reconciliation across the mine value chain is an often underestimated and underutilised aspect of mining operations – but an area Rayleen is passionate about improving across the industry. Communicating with mine sites globally and across commodities provides her with a solid benchmark for a company within the industry, and her aim is to open up these insights to everyone. It’s a career goal to see all mine sites using reconciliation factors in their results to the share market so that anyone can see how one mine site benchmarks against another.
