Gold doré sits between raw gold dust and a finished bar. Mining teams melt the gold they extract and pour it into rough bar form right at the site, before it goes anywhere near a refinery. A doré bar isn't pure gold; it's usually a mix of gold and silver, with purity somewhere between 60% and 90% depending on the source. A refinery buys the bar, tests it, and processes it further to separate out the pure gold. Africa Aurum sources doré bars directly from artisanal mining operations across Africa. Every bar we sell comes with an assay report showing exact gold and silver content, so refiners and traders know precisely what they're buying before any deal closes. Here's how we source, test, and ship our doré bars.
