Metallurgical accounting
Mining companies worldwide are under pressure to improve corporate governance with respect to metal accounting from mine to product
Metals accounting is crucial for:
- Corporate governance Corporate governance forms an important part of ESG compliance, quantifying losses and emissions. Non-compliance is a risk and could affect your licence to operate.
- Accurate measurements Accurate measurement of production drives unit sales and leads to more revenue.
- Variables and inefficiencies MAX identifies production variables and inefficiencies in mining production. Identify shortfalls, improve processes and reap the rewards.
- Troubleshooting Use MAX to troubleshoot metallurgical process issues, minimising costly losses.

Metallurgical management and accounting made easy
How it works
Capture
Capture and validate critical metallurgical data including recovery, downtime and consumables.
- Spreadsheets
- Assay
- Plant
- Mobile

Manage

Microsoft Excel is not ESG or AMIRA compliant
Why your current process is flawed
We have seen your massive spreadsheets for plant management.
Metallurgical accounting is typically done in a single Excel workbook with many sheets, leading to inaccuracy, duplication of effort, lack of transparency and problems with auditability.
Excel is not ESG compliant!
The problem with using Excel for metals accounting:
- Excel can easily be manipulated
- Insecure and impossible to audit
- Does not allow multiple users access
- Rarely integrates with management information systems
- Rapidly loses traceability to source data
- Possesses serious governance limitations
Designed around the AMIRA P754 code of practice
The industry standard for accurate, auditable and transparent metal accounting
The AMIRA P754 Code of Practice for Metal Accounting sets the standard for reporting mineral production. MAX supports its principles directly, which also underpins the ESG governance your board and auditors now expect.
Centralised, auditable data management

Features
Everything a metal accounting team needs, in one system
From data capture on the shift through to the reconciled month-end pack.
MAX covers the full metal accounting cycle: capture and validate plant data, hold it in one audited database, calculate balances with transparent formulas, and report with confidence. Built for metallurgists, process engineers, plant managers and technical services teams.
One auditable source of truth
Every measurement, assay and adjustment lives in a secure relational database with a full audit trail, not in a spreadsheet on someone's desktop.

MAX replaces the sprawl of monthly workbooks with a single, centralised database. Each value records who entered it, when, and from which source, and every later change is versioned so you can always answer “what did we report, and why?”.
- Full history of edits and adjustments with user and timestamp
- Adjusted values kept alongside the original measurement, never overwritten
- Multi-user access with concurrent, conflict-free data entry
- Designed for the AMIRA P754 principles of traceability and transparency
Capture data from every source
Import assays, plant readings, survey results and downtime from spreadsheets, LIMS exports and historians, with validation applied on the way in.

Reusable import definitions map your existing spreadsheets, laboratory exports and plant historian extracts onto MAX measure points. Validation rules flag out-of-range or missing values at the point of entry, so problems are caught on the shift they happen rather than at month end.
- Spreadsheet and CSV import with saved column mappings
- Manual entry worksheets for shift readings and stock takes
- Numerical, categorical, text and file custom fields on any record
- Mobile-friendly web forms for readings captured in the plant
Transparent formula management
Metal balance calculations are defined as named, versioned formulas that every user can inspect, so there is no hidden logic behind a reported number.
Read more Show less
Recoveries, contained metal, moisture corrections and consumable rates are all expressed as formulas held in the system, grouped by processing area and unit of measure. Each formula states how it aggregates (evaluate then sum, or sum then evaluate), and changes are tracked, so an auditor can trace any figure on a report back to its inputs.
- Formulas organised by circuit: crushing, milling, gravity, leach, elution and more
- Explicit aggregation rules for daily, weekly and monthly roll-ups
- Unit-of-measure aware, with conversions handled by the system
- Change history so past periods still reproduce their original results
Metal balance and reconciliation
Track tonnes, grades and contained metal through every stage of the plant and reconcile against shipments, stocks and survey results.

MAX applies mass balance principles across your flowsheet so that feed, product, tailings and inventory tie together. Period-end reconciliation compares the accounted metal with what was physically measured and highlights the gaps that need explaining.
- Mass and metal balance across measure points you define
- Period reconciliation with adjustment workflow and approval
- Stock and inventory tracking for in-circuit and on-hand metal
- Budget values and budget analysis dashboards for variance reporting
Downtime and delay accounting
Record planned and unplanned delays against equipment and shifts, then report availability, utilisation and the true cost of lost production.
Read more Show less
Every stoppage is logged against its equipment, cause and duration. Downtime feeds directly into availability and utilisation reporting, so throughput conversations start from the same numbers the operators entered.
- Delay categories and equipment hierarchy configured to your plant
- Availability, utilisation and mean time between failure reporting
- Downtime dashboards by shift, crew, cause and equipment
- Consumable usage tracked alongside runtime
Shift, daily, weekly and monthly reporting
Standardised production reports and interactive dashboards are ready as soon as the data is in, with no spreadsheet assembly required.
Read more Show less
Period reports are generated from the same formulas that drive the balance, so the daily report, the month-end pack and the board summary never disagree. Dashboards let metallurgists explore trends without exporting anything.
- Period reports for shift, day, week, month and custom ranges
- Dashboards with charts, gauges and grids you can filter and drill into
- Export to Excel, PDF and Word for distribution
- Scheduled report delivery to stakeholders by email
Shipments, bullion and product tracking
Manage gold bar production, doré shipments and concentrate consignments through to refinery certificates and final settlement.
Read more Show less
From gravity gold to the smelt, MAX tracks each bar, lot or consignment with its weights and assays, and reconciles mine-site figures against refinery or customer certificates.
- Bar and lot registers with weights, fineness and assay results
- Shipment consignments with chain-of-custody records
- Certificate reconciliation against site accounting
- Revenue-ready contained metal figures for finance
Roles, permissions and security
Separate data entry, review and approval across roles, with single sign-on through your Microsoft identity and every action logged.
Read more Show less
Segregation of duties is built in. Operators enter, metallurgists review, and managers approve, each with permissions scoped to what they need. MAX integrates with Microsoft Entra ID for single sign-on and multi-factor authentication.
- Role-based permissions down to individual fields and actions
- Single sign-on with Microsoft Entra ID (Azure AD)
- System log of user actions, errors and approvals
- Encrypted in transit and at rest on Microsoft Azure
Site map and plant model
Model your site's locations, plant areas and equipment once, then use that structure everywhere data is captured and reported.
Read more Show less
MAX holds a structured model of your operation: sites, locations, plant areas, equipment and measure points, visualised on aerial imagery. That model drives the navigation, the import mappings and the reporting hierarchy, so a new circuit or stockpile is added in one place.
- Sites and locations plotted on satellite imagery
- Equipment and plant hierarchy for downtime and consumables
- Measure points and data categories configured per area
- Supports multiple sites and commodities in one system
Tasks, workflows and approvals
Period close, adjustments and data reviews follow defined workflows with tasks assigned to the right people and progress visible to everyone.
Read more Show less
Month-end is a sequence of steps, not a scramble. MAX assigns tasks for data checks, reconciliations and sign-offs, records who completed each one, and locks the period once it is approved.
- Configurable workflows for period close and adjustments
- My Tasks view for each user, with notifications
- Period locking after approval to protect reported figures
- Projects and tasks for improvement initiatives
