Mining & Exploration: Operations: Mine Planning and Optimization: What is the conversion rate of your resources and reserves?
Presenter: Edwin Peralta, Wood’s Mining & Mineral Consulting
When: Monday 24 Feb, 2:05pm
Resources to Reserves conversion factors for open pit deposits, have a relatively high percentage of the Measured and Indicated blocks converted to Proven and Probable, less so for deposits amenable only to underground mining. Discussions about Rate-of-Conversion of Resources to Reserves often in underground mining does not treat critical modifying factors carefully. To name just a few: Optimal SMU size selection allowing the best prediction of the in-situ tons and grades and the diluted head grade sent to the mill. Besides considering proper resolution of the geometry of the deposit it should consider recovery and dilution associated with the selected mining method. Over-simplification of the deposit geometry is not as much a concern of the resource geologist as it will be for the mining engineer. Breakeven cutoff determination by resource geologist may omit some operating costs (mine, mill, G&A, mine access). Costs associated that are applied with modifying factors that geologist generally does not consider that might result in overly optimistic cut-off applied to the resource estimate.
