Our Refinery
From raw gold to certified bullion
Our refining operations transform alluvial gold, artisanal doré and scrap gold into high-purity bullion. Each lot follows a controlled, documented process from intake to final pour.
Our refining process
Intake and weighing
Each lot is registered, photographed and weighed on calibrated scales in the presence of the client or their representative. A unique lot number is assigned for full traceability.
Pre-melt assay
A sample is taken and tested (XRF and fire assay) to establish the initial fineness and detect impurities or foreign metals.
Smelting
The gold is melted in a controlled furnace to produce a homogeneous doré bar. Slag and non-metallic impurities are removed.
Refining
Depending on the target purity, we apply aqua regia chemical refining or miller chlorination to remove base metals and silver, raising the gold to 99.5% or 99.9% fineness.
Final assay and certification
The refined bar is re-tested. Weight, fineness and lot number are stamped on the bar and recorded on the assay certificate.
Sealing and release
Bars are sealed, documented and either released to the client or moved to secure storage pending export.
