Resource models you can defend, drillholes that convert.

Every reserve starts as a block model, and every block model starts as drillholes. Our Exploration and Block Modeling services cover the geological side of the value chain: the model itself, the drilling that supports it, and the selectivity assumptions that connect it to mining.

Mineral resource block models — creation and audits

We create and audit resource block models using Inverse Distance (ID), Ordinary Kriging (OK) and Multiple Indicator Kriging (MIK) — every estimation choice documented, every parameter defensible, and classification reviewed against drill support.

Drill hole optimization

We analyze where additional drilling converts the most resource from Inferred to Measured and Indicated, so the exploration budget targets conversion — not just meters.

Bench height and SMU studies

We model different Selective Mining Unit sizes and bench heights and develop a plan for each, looking at revenue per scenario — because selectivity quietly sets your dilution and ore loss.

Reserve reporting alignment

The block model behind your mine plan must be the same one behind your public reserve statement — same version, same assumptions, same classification. We verify that chain from drillhole to report, supported by our Technical Reporting services. Related services: Ore Control Database Management · Metal Reconciliation · Cut Off Grade (COG) Analysis
