Services

Six services.
One workflow.

A single sample can pass through every station — assay, melt, refine, mint, report — without ever leaving our custody. One barcode, one certificate, one settlement.

Certified Assay

XRF for non-destructive screening, fire assay as the gravimetric anchor, ICP-MS to trace-level accuracy. A signed spectral report is issued within the same shift.

Industrial Refining

Induction melting, aqua regia parting, Miller chlorination, and electrolytic finishing for gold, silver, platinum, and palladium — engineered for reproducible 999.9.

Custom Minting

Bars, medallions, and short-run bullion. In-house CAD, die-cutting, alloying, hydraulic strike, and tamper-evident capsule assembly — from proof to production.

Gemstone Recovery

Controlled aqua-regia dissolution frees diamonds, sapphires, emeralds, and rubies from their settings — returned to you graded, weighed, and photographed.

Sweeps & Reclaim

Bench sweeps, filter cloths, crucible residues, and dental burnables — processed at recovery rates most refiners write off. Nothing is thrown away.

Custodial Reporting

A real-time custody dashboard, itemised settlements against your chosen LBMA fix, and cryptographically signed certificates ready for audit or export filing.

Punch in karat, weight, and currency for a live indicative payout benchmarked to today's LBMA fix — before you commit to a formal certified assay.
