Refining

From doré to 99.99% fine, fully documented.

Refining is where value quietly goes missing, and where almost nobody is watching. We run the floor the other way — every lot is weighed, sealed and logged on arrival, and that lot number follows the metal through the furnace to the bar it leaves as.

Doré, scrap, jewellery stock and mine output are all accepted. What returns is 999.9 fine gold, cast or minted to your specification, serialised, and issued with the assay that proves it.

Refined in Vientiane, documented for the region.

Intake, furnace, assay and vault sit inside one secured facility, so metal stays in our custody from the moment it is weighed to the moment it is released. Nothing is subcontracted, and nothing moves between buildings.

Melt, pour and cast follow a written procedure with a witness at every transfer. Torch work is used only where a lot is too small to justify the furnace — the documentation is identical either way.

Every bar leaves with an assay result, a serial number and a weight recorded to the milligram: the three figures a buyer checks first, issued together.

A refinery is only as good as the paperwork it can still produce a year later. We document to that standard, not to the moment of sale.
