Making a copper resource model reproducible end to end
Copper project technical services team (representative engagement)
Challenge: Estimates were rebuilt by hand each cycle from exported spreadsheets. Nobody could say with confidence which variogram, search neighbourhood, or composite length produced last quarter's tonnage figure, which made technical review slow and due diligence uncomfortable.
Approach: Ran the chain from the governed project database instead of exports — desurveying logged holes, compositing assays, kriging a block model, and simulating realizations — with every result content-addressed and its manifest recording the kernel, inputs, parameters, actor, and toolchain pins.
Built and validated against a teaching deposit of 24 diamond holes and 1,522 assayed intervals held in the platform's own project database.
