Metal Accounting Assurance
Independent, evidence-based assessment of the systems and controls that determine the credibility of reported metal.
Confidence requires more than a balanced spreadsheet
Reported metal is created through a chain of physical measurements, samples, laboratory results, inventory estimates, calculations, data transfers, reconciliations and management controls. Weakness in any part of that chain can affect operational decisions, financial reporting and confidence between functions.
Process Metal provides an independent technical view of this complete system. The assessment identifies where confidence is well supported, where material risks remain, and which actions will provide the greatest improvement.

Laboratory & Inventory
- Sample preparation and analysis
- Laboratory QA/QC
- Stock and in-process inventory
- Survey and density methods
- Timing and cut-off controls
Systems & Governance
- Data capture and interfaces
- Calculation and spreadsheet logic
- Reconciliation methodology
- Standards, procedures and accountabilities
- Review, approval and change control

Typical deliverables
Executive Assurance Report
A concise view of confidence, material risks, strengths and priority decisions.
Evidence-Based Gap Assessment
Findings linked to objective evidence, risk and relevant principles or internal requirements.
Prioritised Improvement Roadmap
Actions sequenced by materiality, practicality, ownership and implementation horizon.
Control & Governance Matrix
Critical controls, accountabilities, review requirements and required evidence.
Calculation Integrity Review
Targeted review of spreadsheets, databases, interfaces and reconciliation logic.
Implementation Verification
Independent follow-up to confirm that agreed changes operate as intended.
Flexible scope, consistent assurance discipline
The engagement can be applied to one process area, a complete operating site, multiple assets or a corporate governance framework. The scope is scaled to the client’s risk profile and decision requirements.
Common engagement triggers
- Persistent reconciliation or grade variance
- Limited confidence in inventory or production figures
- Different site practices across a group
- System replacement or digital transformation
- Audit, transaction or financing readiness
- Need for independent executive assurance
Standards and alignment
Assessments can be aligned with AMIRA P754 principles, company standards, financial-control requirements and other client-specific governance expectations.
The objective is proportionate, practical assurance—not a formulaic compliance exercise.
