Geostatistics software & consulting for mining
From drill holes to defensible resource models
Mining decisions are made with incomplete information. Geovariances helps you quantify what you don't know, so your resource models hold up to investor and regulatory scrutiny.
Geostatistics changes what mining decisions are based on.
What you gain
Resource estimates you can defend
- Reproducible results from one update to the next
- Full parameter traceability for investor and regulatory reporting
- Compliant with JORC, NI 43-101, and CIM requirements
Smarter drilling, lower investigation costs
- Identify where additional sampling genuinely reduces uncertainty
- Optimize drill spacing before committing to a campaign
- Maximize resource uplift per meter drilled
Mine plans grounded in the full range of outcomes
- Move beyond a single grade model to a set of equally probable scenarios
- Quantify NPV distributions and downside risk before capital commitment
- Align resource classification with mine planning from the start
Mining challenges we solve
Mining decisions are made with inherently incomplete information. The question is how well you quantify what you don't know.

Challenge #1
Our resource estimate varies too much between updates.
expand_more
Inconsistent estimates create mistrust among investors and regulators. Geovariances' geostatistical methods — kriging, conditional simulations, and local uncertainty quantification — deliver estimates that are reproducible, traceable, and defensible under regulatory scrutiny.

Challenge #2
We're drilling too much, or in the wrong places.
expand_more
Drill holes are expensive. Geostatistical analysis identifies where additional sampling actually reduces uncertainty and where it doesn't, allowing you to optimize drill spacing, reduce campaign costs, and maximize resource uplift per meter drilled.

Challenge #3
Our Measured / Indicated / Inferred split is hard to justify.
expand_more
Resource classification decisions have direct financial and regulatory consequences. Isatis.neo provides geostatistical classification tools, including kriging efficiency, slope of regression, and sampling density variance, that give you a quantitative, auditable basis for your classification decisions.
crisis_alert
Challenge #4
Our mine plan doesn't reflect what could go wrong.
expand_more
A single estimated grade model feeds a single production plan, with no visibility on downside risk. Conditional simulations generate a range of equally probable grade models, enabling probabilistic mine planning, NPV distribution analysis, and explicit risk management before any capital commitment.
From data to decision
Three stages. One platform. Full traceability.
From data to spatial model
Clean data, robust variogram, defensible estimation parameters.
From model to uncertainty
Reliable block estimates, local confidence intervals, probabilistic grade-tonnage curves.
From uncertainty to decision
Resource classification, drill optimization, mine planning under risk.

Everything you need to know before getting in touch
How does geostatistics quantify uncertainty in resource estimation? expand_more
Geostatistics quantifies uncertainty through two complementary approaches. Kriging variance provides a local confidence indicator at every estimated block, quantifying how reliable the estimate is given the available data and the spatial continuity model. Conditional simulations generate a set of equally probable grade models, each honoring the sample data and reproducing the variogram — allowing you to compute grade- tonnage distributions, confidence intervals on resources, and NPV risk profiles. Together, these approaches replace a single best estimate with a full probability distribution of outcomes.
What is conditional simulation, and how does it differ from kriging? expand_more
Kriging produces the most probable estimate at each unsampled location and minimizes the estimation variance, but it smooths out the natural variability of the deposit. Conditional simulations generate multiple equally probable realizations of the grade distribution, each reproducing the statistical properties of the original data (histogram, variogram) while honoring the sample values. The result is a set of scenarios that reflect the full range of possible outcomes rather than a single smoothed model, essential for risk quantification, mine planning under uncertainty, and sensitivity analysis.
Is Isatis.neo compliant with JORC, NI 43-101, and CIM standards? expand_more
Yes. Isatis.neo is used by resource geologists and competent persons worldwide to produce mineral resource estimates compliant with JORC, NI 43-101, and CIM reporting standards. The software provides fully justified and traceable estimation parameters, complete audit trails, and reproducible workflows, all required for compliant resource reporting. If you have questions about compliance for a specific jurisdiction or reporting standard, our geostatisticians can advise you directly.
