Identified
Code associated with the lot

Home / Traceability
Every lot moves forward with its identity, weight, assay and responsible parties recorded. The doré bar does not erase its history: it concentrates it in a verifiable file.
What we trace
Traceability begins before we receive the ore. We review the available documentation on the supplier and the source operation to decide whether the lot can enter our chain.
When the material is received, it is assigned an identity that follows its weighings, samples, assay results and transformations. This links what enters the process to what ultimately leaves it.
The goal is concrete: for the doré bar to retain a documentary link to its source lot and to the controls performed during processing.
Chain of custody
The record is built during the process, not at the end. The animated flow shows how every control adds evidence to the same lot.
Provenance and the documentation of the operation delivering the ore are reviewed.
Supplier · operation · lotThe material is identified, weighed and recorded before entering the process.
Code · weight · dateA representative sample determines the composition and grade of the lot.
Sample · assay · resultInput materials, transformation and the resulting mass balance are recorded.
Charge · process · balanceThe bar is weighed, identified and linked to the source lot file.
Code · weight · provisional gradeThe lot identity connects every input, control and transformation.
Evidence
Each control answers a different question. Together they reconstruct the journey without relying on a single declaration.
| Supplier identity | Available data and documents for the party delivering the material |
|---|---|
| Provenance | Source operation and reference for the lot received |
| Weights | Inputs, internal movements and outputs used to review the mass balance |
| Assay | Sample, method and result associated with the lot |
| Responsible parties | Record of handovers and controls at every stage |
| Product obtained | Code, weight and relationship between the doré bar and its lot |
Intermediate result
A doré bar is a semi-refined alloy containing gold and other metals. It still requires further refining to reach the commercial purity required by the buyer.
Traceability does not end here: the code, weight and provisional assay remain linked to the file built from the source. That continuity lets the metal be followed into refining and export.

Custody
Changes of responsibility, transfers and controls are recorded to preserve continuity between the source, the process and the doré bar.
