Mine Geology, Grade Control and Reconciliation

Understanding geological controls of orebody leading to optimised mine planning and profitability

In any mining operation, understanding the geology of the orebody and waste rocks is fundamental for successful resource estimation, geotechnical engineering, mine planning and mineral processing.

Better geological interpretations at the mine scale improve grade control, mine planning and profitability. Our consultants are leaders in understanding ore-forming processes.  With a unique combination of structural geology and practical mining geology experience, we can assist you to improve your mine development, operations and near mine exploration. Our experience and integrated approach will give you better near mine exploration targets, optimise mapping and grade control, reduce the risk of misdirecting ore and unintentional dilution, and improve the reconciliation of your mine.

Production pressures can make it difficult to maintain geological input. We can help you by providing regular geological mapping campaigns, as well as hands-on training of your staff at your mine site to capture geological data effectively. Understanding grade distribution and optimising mining selectivity through grade control and reconciliation is essential to achieving the mine plan and improving business performance. When analysing grade control methodology, SRK considers detailed geological controls on grade distribution, optimal sample spacing, sample collection, sample preparation and analysis, quality control, and costs and benefits to ensure  your grade control and reconciliation processes are fit-for-purpose and meet best practice.

Our approach to geology, grade and mineralisation controls in the mine environment is based on addressing the material issues that affect the entire mining cycle from resource estimation to mine closure. Your operation benefits by ensuring that sound geological, grade and geometallurgical models underpin the entire mining process.
