A decision-oriented technical diligence checklist with evidence requests, unresolved assumptions and transaction follow-up priorities.

A mining acquisition checklist is most useful when it controls evidence and decisions. A folder containing a document is not proof that the underlying assumption is sound. For each topic, record what was reviewed, what the evidence supports and what remains unresolved.

1. Define the transaction and intended operating case

Identify the property, proposed activity, decision deadline and intended users of the review. Establish whether the buyer plans continued operation, an expansion or a restart. Confirm review scope and specialist reliance requirements before collecting an unfocused data room.

2. Request the technical and operational evidence

3. Reconcile the records with the proposed plan

Check dates, units, asset identifiers and the configuration represented by each record. Historical plant output may involve different feed or equipment. A cost quote may exclude installation, utilities or mobilization. Note whether the planned production level requires development or infrastructure absent from the acquisition budget.

4. Create a material-issue register

For each issue, record the source, observation, implication, missing evidence, responsible reviewer and required resolution. Distinguish a confirmed deficiency from an untested assumption. Classify the issue by its effect on acquisition terms, development choices, startup timing or further investigation. Avoid assigning numerical certainty where the underlying evidence is incomplete.

5. Close the review with decision conditions

Specify which issues must be resolved before commitment, which may be addressed through a defined work program and which need ongoing monitoring. Obtain current specialist input where title, mineral resources, environmental liability, formal valuation or professional engineering requirements fall outside the practical technical review.

The final checklist should identify limitations and outstanding questions as clearly as it identifies completed work. A technically polished report cannot remove uncertainty in areas that were inaccessible, untested or excluded. Ensure the decision-maker understands those limits before relying on the findings.

General technical information, not a site-specific compliance determination. Review scope, mine conditions and applicable requirements must be established for each engagement.
