Porphyry Copper Exploration

Given the same data, Mohan builds a better subsurface model than any existing tool.

Mohan builds generative subsurface world models for porphyry copper exploration. We combine real drillhole data, physics-constrained modeling, and expert geological reasoning to produce probabilistic 3D subsurface models.

Real drillhole data
Physics-constrained priors
Captured expert reasoning
Hard
Real drillhole data is treated as hard constraints that valid models must honor
Soft
Expert geological reasoning is encoded as soft probabilistic guidance
3D
Outputs are probabilistic 3D subsurface models rather than a single interpretation
The Problem

Subsurface uncertainty, unaddressed

Industry-standard tools produce a single deterministic model based on intuition. One interpretation. No measure of confidence.

No uncertainty quantification

You get one model, not a probability distribution. You cannot know how confident to be in any given interpretation.

No physical consistency

Interpolation does not enforce geological laws. The resulting model may be statistically smooth but geologically implausible.

No systematic integration of expert knowledge

The geologist's intuition shapes the parameters, but this reasoning is never made explicit or reproducible.

Our Solution

A generative subsurface world model

Mohan fuses three data sources to produce not one model, but a probability distribution: tens of thousands of geologically valid subsurface architectures consistent with your data.

Real drillhole data

Treated as hard constraints that any valid model must honor.

Physics-constrained synthetic priors

A generative model trained on synthetic porphyry copper systems consistent with geological formation laws, providing the best possible prior over subsurface architecture.

Captured expert reasoning

Geological knowledge encoded as soft constraints via LLM reasoning, integrating how expert geologists interpret data rather than just what they conclude.

Model outputs
Compute per-voxel copper grade estimates and their variance
Quantify uncertainty at every point in the subsurface
Optimize drilling sequences to reduce total holes needed
Guide mine development decisions with calibrated confidence intervals
How It Works

An integrated three-part architecture

A synthetic data generator, a diffusion-based generative model, and a drill sequence optimizer, all working together end to end.

Use Cases

Value across the mine lifecycle

From early-stage exploration through production, Mohan fits into your existing workflow.

Phase A: Exploration & Drilling

Optimize drill sequencing, reduce total holes needed, and shorten time to resource definition.

Phase B: Mine Development & Production

Guide mine development decisions with calibrated confidence intervals, uncertainty maps, and better ore body delineation.

Outcomes

Better models, better decisions

Quantify uncertainty at every point, optimize drilling sequences, and make mine development decisions backed by data instead of intuition.

Probability distribution

Not a single best guess, but tens of thousands of geologically valid models consistent with available data.

Drill sequence optimization

Generate model samples, score candidate locations, and prioritize where to learn the most.

Mine development decisions

Use calibrated confidence intervals and uncertainty maps for downstream planning.
