Resource estimation & geological modelling (NI 43-101/JORC)

Auditable mineral resource estimates that withstand investor and exchange scrutiny. We integrate geological interpretation, domaining, geostatistics and classification to NI 43-101/JORC, supported by robust QA/QC and density workflows. Our models are designed for mine planning: practical selectivity, dilution/ore loss and reconciliation, with uncertainty commentary and clear reporting.

From data quality to code-compliant MRE

We begin with database validation and sampling QA/QC (standards, blanks, duplicates), followed by geological interpretation and wireframing. Domaining reflects lithology, alteration and structure; variography informs the estimation method (OK, MIK or IDW) and search strategy. Density workflows are explicit, with checks against lithologies and reconciliation where possible.

Models built for engineering, not just reporting

Block models include practical selectivity, dilution and ore-loss treatment so planners can optimize cut-off, stockpiles and schedules without rework. Classification criteria are transparent, aligned to NI 43-101/JORC/CRIRSCO, and supported by swath plots, QQ plots and cross-validation. Uncertainty is documented so trade-offs and scenario planning remain defensible.

Deliverables that accelerate decisions

What you receive:

clean block models, validation graphics, audit trail of assumptions and a QP-signed report ready for disclosure.

Why it matters:

fewer surprises, smoother reserve conversion and stronger confidence from boards, lenders and exchanges across the Nordics and EU.
