Mineral Resource & Reserve Reporting AI Agent

Assemble the drill-hole lineage, the QA/QC record and the modifying-factor evidence behind a resource and reserve statement, mark what the pack does not support, and hold it for the Competent Person who consents.

What this agent does

Assembles the evidence, not the classification

In
01

A hole is logged, and its assays, QA/QC inserts and the extract behind the estimate are pulled with it.

02

A statement is prepared, and each figure is traced to the database extract current at the effective date.

Reason
03

A Table 1 section is opened by activity under JORC 2012, mandatory since 1 December 2013, and silent rows listed.

04

A reserve is converted, and each modifying factor is set beside the study, testwork or permit status behind it.

05

An announcement repeats a figure, and it is matched to the statement, the consent and any drilling since.

Decide
06

A prior statement is compared, and the movement is split by depletion, model, price and method, never netted.

07

A consent goes on file under NI 43-101 s.8.3 as consolidated 9 June 2023, with the document version read.

Out
08

A study level is set, and the technical report summary item set follows 17 CFR 229.601(b)(96), which scales.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent assembles the support; the assay copilot proves the data on import, and a named Competent Person consents to the figure.

Example workflow

One statement, data to consent

AgentHuman
1Estimate receivedDrill-hole database, assay certificates, model run and effective date
2Lineage assembledQA/QC records, Table 1 support, modifying-factor evidence and tenure status
3Pack draftedLineage map, silent Table 1 rows, open gaps and confidence
4Controls appliedSource-trace checks, code-section checks, consent-currency checks and confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing is reported at any of them — the agent is assembling, and the Competent Person's lane opens at the confidence gate.

5DecisionSplits at the confidence threshold
High confidence

Goes to the Competent Person to read.

Low confidence

Adds a peer-review geologist read first.

Competent Person review

The pack is held with its lineage, its silent rows and the confidence.

Accept · Annotate · Send to peer review
Accepted — pack complete

7Outcome evaluatedLineage coverage, annotations, silent rows and post-statement corrections
Annotations

Every Competent Person annotation is counted in the evaluation.

What should not run autonomously

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every reported figureFrom the drill-hole database
03Assembly

Assemble from the record

Draw on the extract at the effective date, the QA/QC record and the studies on file.

01Approved path

The Competent Person carries it

Routine lineage, Table 1 support and cross-references arrive already assembled.

02Human review

Send review to the thin support

Silent rows and low-confidence packs are marked, so the Competent Person starts where the support is thinnest.

04Build an evidence trail

The figure, the drill data beneath it and the person who consented stay on the statement.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Six layers between the model and the statement

Each of the six sits inside the last. What none of them catches appears in the map beneath this.

L6Rollback / safe modePull assembly back to lineage-only when evaluation or production signals degrade.Roll back

How Nestack evaluates it

Evaluate the whole reporting workflow — not only the statement that ships.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the figure the market reads
Depth of coverage ▼
E1Final-output evaluationDid every reported figure trace back to a source record?
E2Step-level evaluationDid the agent read the extract current at the stated effective date?
E3Tool evaluationDid it read and write the correct deposit and the correct model run?
E4Confidence calibrationDo low-confidence packs actually attract more annotations?
E5Slice evaluationHow does performance change across specific deposits and estimate types?
E6Business outcomeHow many packs were corrected, retracted or refiled after the statement went out?

Affected slices

A clean statement can hide one deposit

A statement-level lineage-coverage figure can read complete while a few deposits carry almost all of the unsupported rows. Nestack reports the unsupported-figure rate by deposit, not only in total.

Evidence-linked improvement

Nothing closes without a new case

The loop shuts when the unsupported figure is a regression case. That suite is what the next statement prepared is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Unsupported-figure rate rises in a deposit.

02Diagnose

The tonne that was reported before the assay behind it was reconciled is read back until one cause is left.

03Improve

Any change goes out numbered, with the figures that caused it attached.

04Verify

One statement case still failing is enough to hold the release back.

05Learn

One case joins the suite, one line joins the estimation record.

Learn → DetectThe return edge. The next statement is prepared against a suite one case longer.

Four phases across six weeks

Each band covers the weeks its own phase really needs, and that is why week five holds two of them.

Pilot & Launch W5 – W6

At the end of W6Once the statement validates, Agent Care assumes the running agent.

Next step · Mining AI agent

Build a reserve-reporting agent around the Competent Person's consent.

Show us your drill-hole database, your last statement and the people who consent. A named Competent Person carries every reported figure, and this is the page our geological assay copilot defers to when it says so.
