A decade of mining operations experience has inspired me to unveil the hidden stories that rarely see the light of day. From the gritty rock face to the boardroom decisions steering mining companies, the choices made on the ground reverberate to the highest echelons with profound effects on the outcomes that C-level executives care about. During the daily grind, these choices often go unnoticed, yet they are the architects of a mining operation's destiny. This prompts a series of discussions bridging practical actions with strategic visions. Starting with one that’s neat: Mine-to-Mill reconciliation. It's basically comparing what we thought we'd dig up against what we got as final product. Simple, right? But it tells us a whole lot about where we're nailing it and where we need to up our game. Reconciliation goes beyond the science of estimation; it's the critical bridge that connects our forecasted models with the tangible outcomes in the field. For Geostatisticians, geologists, and mining planners, the focus often zeroes in on the accuracy of block models and the efficacy of mining sequences. Yet, for managers and shareholders, reconciliation serves a broader strategic purpose. It's a test that answers a fundamental question: Are we delivering on our promises to the market? Every dollar spent on operational expenses (OPEX) and capital expenditures (CAPEX) is a commitment—not just to operational viability but to generating the expected cash flow and product yield. Thus, reconciliation straddles two realms: the technical and the strategic. It validates the scientific rigor of our mineral resource estimations while simultaneously holding us accountable to the financial and production targets set before investors and stakeholders. My journey from hands-on Resource Geologist to strategic Mine Technical Services Manager has bestowed me with a panoramic view of mining operations. Effective reconciliation isn't just about intricate science; it's about aligning production with investor, stakeholder, and market expectations. A Practical Roadmap: 1. Data Mapping: Start by mapping your existing data—long-term and short-term block models, surveys, dispatch records, truck scales, plant sampling, and mass balance data. This is the foundation of reconciliation, helping you turn numbers into valuable insights. 2. Choose Reconciliation Frequency: In the next stage, determine how often you'll conduct reconciliation. It could be monthly, yearly, or quarterly, tailored to your company's unique needs. Keep in mind that a monthly frequency may not yield accurate results if you have substantial intermediate stock or lack monthly surface surveys. Adapt your comparison factors to align with your operational reality. 3. Dive into Comparisons: Understand that criticism and comparisons are essential. Just dividing numbers may not reveal the full picture. Be curious and dig deeper into your data to uncover meaningful insights. 4. Embrace Criticism and Adapt: Welcome criticism and foster a culture of continuous adaptation. Share your results openly, even if they raise questions. Embracing feedback and learning from it is integral to refining and enhancing your reconciliation process. I would like to share a practical example of reconciliation, offering you a glimpse into a typical surface nickel mining operation with a blending process. It's a dynamic and intricate system where raw ore from various sources is meticulously blended to achieve the desired product composition. Reconciliation is more than just crunching numbers; it's a commitment to excellence, transparency, and growth. I invite you all to be part of this journey. Feel free to drop your questions, share your thoughts, or send me a message— I'm more than happy to share my knowledge and insights for free. Let's explore the depths of this vital process together, and together, we can shape the future of mining operations.
