Exploration Strategy Implications of a Flat Al₂O₃ Profile in CIDsA flat alumina profile might not sound glamorous, but it's a hidden gift when you're plotting out your next exploration move. Here's how it reshapes your approach: Strategic AdvantagesSimplified Resource ModelingConsistent Al₂O₃ grades reduce the need for complex domaining or zonation within the pisolitic layer.You can assume lateral homogeneity, making block models cleaner and more predictable.Efficient Sampling ProtocolsNo need for vertical grade control drilling just to check for alumina variability.Surface sampling and shallow RC drilling are enough to model the alumina distribution confidently.Optimized Metallurgical PlanningSince alumina is relatively stable throughout the channel, composite samples from varying depths will give representative metallurgy results.This avoids under- or overestimating impurities in process simulations.Lower Exploration RiskPredictability equals reliability. You avoid surprises as drilling progresses, which streamlines budgeting and decision-making.Especially valuable when targeting remote mesas or areas with limited outcrop. Tactic Shift: What to Focus On InsteadPhosphorus & Silica Variability: These often fluctuate more dramatically with depth or facies changes—monitor them closely.Channel Architecture: Look for structural controls that may impact grade thickness or ore continuity.Lateral Extensions: If alumina remains flat vertically, the real exploration win is expanding laterally—channel tracing becomes key.A steady alumina profile frees you to focus on the variables that do change and affect processing. It's like having one less wild card to worry about. Want to dig into how this applies to your Cane Bore strategy or another CID target you’re considering?
