Recent scrutiny of the US Mint has put a longstanding challenge for the gold industry back in focus: how can refiners establish where the gold entering their supply chains actually came from?

Against this backdrop, Source Certain Founder and CTO Cameron Scadding spoke with Mining.com.au about the growing importance of gold provenance and why refineries represent a critical point for identifying higher-risk material before it enters the legitimate gold supply chain.

The feature looks at the limitations of relying on documentation and refinery stamps alone, and the role independent origin verification can play in providing evidence of geographic origin. It also highlights how this approach is already being applied in Australia, with ABC Refinery COO David Woodford discussing the refinery’s long-standing use of Source Certain technology to independently verify the stated origin of every batch of mined gold it receives.

As scrutiny of global mineral supply chains increases, the discussion reinforces a fundamental issue for responsible sourcing: confidence in how gold was sourced depends first on knowing where it actually came from. Independent origin verification provides that evidence at a point in the supply chain where organisations can still act on it.
