Tolun AI · Agentic AI for mining exploration

Live in production · 4 countries validated · Ed25519 provenance

Joint inversion, with proof.

Tolun AI is the agentic platform for mining exploration — 13 specialist agents that run joint probabilistic inversions over your survey data, ground every claim in the posterior, and sign the result with Ed25519. Built for the QP, not the demo.

Why this matters

Three things every other vendor gets wrong.

01
Joint, not stacked

One posterior across gravity, magnetics, EM, MT, surface waves, heat flow, and 10 more forward models. Not a stack of independent inversions reconciled by hand.

For the QP: a single self-consistent earth model — no reviewer asking which physics you trusted.

02
Posterior, not point

Every density, depth, and contact ships with a credible interval. Drill targets are ranked by probability of intersection, not by the modeller's confidence.

For the QP: defensible uncertainty bounds for JORC / NI 43-101 / SK-1300 disclosures.

03
Signed, not asserted

Each result is hashed and Ed25519-signed against a published key. The audit trail is mathematical — anyone can verify provenance from the public JWKS endpoint.

For the QP: a competent person's report you can defend if challenged in a tribunal.

Live benchmarks

Four validated regions. Public data only.

Run any scenario yourself in under 10 seconds. The same code that produced these numbers runs in the live demo.

The pipeline

From survey to drill target — one posterior, no handoffs.

3D scientific render of a vertical well-log piercing a layered seismic voxel cube with rainbow stratigraphy — the canonical inversion → drill-target visualization.
Stage 01

Upload

CSV, NetCDF, GeoTIFF, ASEG-GDF. Survey-grade dataset of any of 16 supported physics.

Stage 02

Joint inverse

MCMC (1D) or bounded Tikhonov (2D/3D) over all selected channels at once. Numba-JIT forward models.

Stage 03

Agent interpretation

13 specialist agents read the posterior and draft narrative geology, QC notes, and target ranking — Claude-grounded, never hallucinated.

Stage 04

Drill target

Ranked targets with probability of intersection, depth-to-top with CI, and the full Ed25519-signed lineage.

All four stages run on the same posterior. No lossy handoffs. No vendor lock.

For the qualified person

Disclosure-ready. Audit-defensible. JORC, NI 43-101, SK-1300.

Tolun AI is a drafting tool, not a truth source. Every claim you make in a competent person's report links back to a hashed, signed posterior — so the audit conversation becomes mathematical, not procedural.

  • Per-result Ed25519 signature against a published prod key.
  • Inputs, mesh, config, and result-summary hashed independently.
  • Public JWKS endpoint — your auditor verifies without our help.
  • Lineage replay: same inputs reproduce the same posterior, bit-for-bit.
