In this two-part episode of Fresh Thinking by Snowden Optiro, Senzeni Matondi, Principal Consultant, joins Melanie Bully, Senior Consultant, to explore why grade control is fundamentally a decision-making discipline, not simply a grade estimation exercise.&amp;nbsp; In Part 1, Senzeni and Melanie unpack the operational and financial consequences of misclassification, including:  Ore loss \u2014 when valuable material is classified as waste and potentially lost forever Dilution \u2014 when waste enters the ore stream, reducing head grade and consuming valuable processing capacity Misclassification \u2014 and why it can result from accumulated uncertainty across sampling, geological interpretation, estimation, blast movement, survey accuracy and mining execution Reconciliation \u2014 and why poor reconciliation can reflect issues across the entire mining value chain, rather than the resource model alone  The key takeaway? A technically sound grade estimate is only useful if it supports the right operational decisions.
