The principle of mine reconciliation is based on the comparison of theoretical and actual data. The aim is to understand the differences, identify the causes and make adjustments to improve future operations. Reconciliation consists of : 1. Comparing estimated and extracted reserves: - Verification of quantities and quality of extracted mineral reserves against initial forecasts. 2. Compare production forecasts with actual production: - Comparison between the quantity of ore forecast for extraction and the quantity actually extracted. 3. Analyze metallurgical yields and recovery rates: - Compare the amount of metal recovered with the forecast, taking into account losses during processing. 4. Analyze dilution and loss factors: - Identify geological and operational factors that can lead to ore dilution and losses in the mining process. Decisions to be made during mine reconciliation: During reconciliation, several strategic decisions need to be made to improve mining, including: 1. Adjustment of reserve estimates: - Revise geological models and reserve estimates based on observed discrepancies between forecasts and reality. This may involve adjusting operating plans and financial forecasts. 2. Modification of extraction methods : - Modify or adapt extraction techniques according to the actual results obtained. For example, if dilution is greater than anticipated, blasting or drilling techniques may need to be reviewed. 3. Metallurgical process optimization : - Improve metallurgical recovery rates by adjusting treatment processes and optimizing equipment utilization. 4. Inventory management : - Adjust inventory and equipment management in line with reconciliation results, ensuring that resources are used efficiently. 5. Review production targets: - Review short-, medium- and long-term production targets and schedules based on actual results. This may lead to an adjustment of financial forecasts and profitability strategies. 6. Improve data quality : - If discrepancies are significant, it may be necessary to review the collection of geological, drilling and metallurgical data in order to improve the quality of information for future reconciliations. To remember: Reconciliation in mining is a crucial step in ensuring the profitability and sustainability of mining projects. Rigorous monitoring of reconciliation can lead to better resource management, more efficient and sustainable operations, and optimized mine performance.
