Domain interpretation, variography, block-model construction and grade estimation – classical geostatistics applied in Leapfrog, with classification aligned to the JORC 2012 Code.
What we do
- Compositing and exploratory data analysis; top-cut / capping strategy
- Variography (including directional and downhole)
- Boundary analysis and domain validation
- Grade estimation – ordinary kriging, inverse distance, nearest neighbour
- Block-model construction and validation; grade–tonnage curves
- Estimation review, peer review and audit
- Competent-person-level support for JORC (2012) resource statements (select gold deposit styles)
We can rebuild, test or peer-review a historical estimate – including reconciling domains, sample-selection and search parameters – so you know what the numbers actually rest on.
