Infill Drilling Plan Optimization
GeoMine-OreChaser (OreChaser, aka DPO) is an infill drilling plan optimizer. OreChaser allows the drill planner to determine the optimum number, positions and lengths of additional drill holes required to maximize the resource uplift for a given drill budget spend. OreChaser features a proprietary 3D Genetic Algorithm with the choice of two search strategies: RocDP (Randomized Ore Chasing Drilling Plane) strategy and (FRD) Fully Random Drilling strategy, both with the objective of minimizing Kriging variances.
OreChaser Key Benefits
OreChaser Feature List
Import assays, attributes (categorical or continuous) and geological structures including faults; Desurvey drill holes with choices of 5 desurvey algorithms; Composite and color-code drill holes by lithology, attributes or assays; Create custom DDH attributes as input to subsequent block model interpolations; Create planned drill holes for drilling planning.
Creates composites from drill holes for use with OreChaser
Given an existing block model, composites and resource classification criteria, determines N-best infill drilling plans each defining number, and positions and lengths of the required additional drill holes that minimizes Kriging variances and maximizes resource uplift for a given drill budget spend.
Choice of two search strategies: RocDP (Randomized Drilling Plane) strategy for targeted drilling and faster convergence, and FRD (Fully Random Drilling) strategy for exhaustive search.
Exports chosen drill plans to CSV files for further processing and/or sharing
