Contract mining
We operate three contract mining sites under long-term agreements: two in west Texas, one in Sonora (MX). Each site is staffed by a salaried Golden Age field geologist plus the host operator’s crew. We finance the equipment, set the work plan and assume the offtake risk; the host operator works the seam. Buyers benefit from a single point of accountability — our name on the bill of lading.
- Five-year typical contract length, with renewal option
- Golden Age geologist on site full-time
- Net-7 payment to host operator (industry average is Net-45)
- Weekly production reports shared with offtake customers on request
Assay & refining
Our Rundberg Lane lab runs fire-assay for precious metals and ICP-OES for trace impurities. Refining is partnered with a 70-year-old Houston refinery; the relationship is exclusive on our outbound doré and audited annually. We also perform third-party assays on consigned material — turnaround is 48 hours for a standard precious-metal lot.
- Fire-assay precision: ±0.05 % on Au, ±0.1 % on Ag
- ICP-OES detection limits at sub-ppm for As, Hg, Cd
- 180-day sealed counter-sample on every shipment
- Third-party assay service available to non-customers
Custom alloys
For jewelry-grade and dental-grade customers we cast custom alloys to formula: green gold, rose gold, 950 silver, sterling, palladium-white-gold, dental-grade Au-Cu-Ag-Pd. Minimum melt is 200 g; typical lead time is six business days from formula sign-off.
- Casting forms: grain (shot), wire, plate, sponge
- Minimum order: 200 g per formula
- Repeatable to ±0.3 % composition between melts
Bonded logistics
We hold a long-term arrangement with two FTZ-bonded warehouses (Houston, Long Beach) and a contract with Brink’s for armored ground transport. Insured high-value shipments are routine for us — we move precious-metal value daily — and we publish a private real-time tracking link per consignment to the buyer’s named procurement contact.
- FTZ-bonded storage in Houston and Long Beach
- Armored ground transport for shipments > $250,000 declared value
- Insurance to $50 M per consignment via Lloyd’s syndicates
- Private per-shipment tracking link, expires on delivery
Supply-chain audits & consulting
For larger industrial buyers — typically electronics OEMs and mints — we prepare and present formal supply-chain due-diligence packages aligned with the OECD Guidance and (where relevant) the EU CRMA. We have led nine such audits since 2021; eight of them with no findings.
- OECD Due Diligence Guidance — five-step framework
- Conflict-Free Smelter Initiative (CFSI) alignment
- Chain-of-custody mapping to host operator, by lot
- Fixed-fee engagements, signed scope-of-work
