Purity you can
measure,
value you can verify.
Assay Pro is a modern precision laboratory for gold, silver, platinum, and palladium. Instrumented refining, orthogonal assay methods, and certificate-backed settlement — for jewellers, miners, and institutional custodians.
A lab built on numbers, not narratives.
We built Assay Pro for a simple reason: the market runs on trust, and trust runs on measurement. Every gram that enters the lab is barcoded, weighed on a calibrated tier-1 balance, and photographed before a single test is run.
Every certificate we sign is defensible in an audit, a court, and a boardroom. We publish our methods, our calibration schedules, and our tolerances — because the number on the page is only as good as the process behind it.
Four disciplines. One traceable chain.
Traceability
Every sample is barcoded on arrival, tracked through each station, and settled against an immutable custody log you can audit at any time.
Refining
Induction melting, aqua regia parting, and electrolytic finishing — engineered to deliver reproducible 999.9 fine gold, batch after batch.
Certified Assay
XRF, fire assay, and ICP-MS run in parallel. Three orthogonal methods, one certificate — accurate to the third decimal, signed within the hour.
Minting
Custom bars, medallions, and short-run bullion — CAD, die-cut, alloyed to spec, struck on hydraulic presses, and sealed in tamper-evident cards.
From doré and scrap to 999.9, without the guesswork.
Whatever arrives — mine doré, factory scrap, jewellery, granules, sweeps — leaves the lab as investment-grade metal with a certificate that stands up to any audit.
- Gold certified to 999.9 fineness
- Silver, platinum & palladium streams
- Aqua regia stone & gem recovery
- Sweeps, filings & bench residue reclaim
Three methods. One number. Signed in an hour.
Non-destructive XRF for screening, fire assay for the gravimetric anchor, ICP-MS to the part per million. When all three converge, our chief metallurgist signs — and the number becomes the settlement.
