A letter from the founder

Eleven years of doing one thing properly.

When I started Golden Age in 2014, the goal was modest: build an American supply company that procurement officers actually wanted to call back. No ten-page brochures, no investor-deck language, no surprise grade variances. Just clean assays, written specifications and shipments that land on the date we promised.

Today we run three contract sites, a small assay lab outside Austin, and a buyer-services team that closes Friday by 6 PM Central. If we ever forget what we’re here for, I keep a copy of our first invoice — 14.6 troy ounces of silver, dated April 2014 — pinned above my desk.

— Hector Flores, Founder & Managing Director

Featured engagement

A three-year doré contract with a Midwest refinery.

In 2022 we won a five-year tender to supply a 120-year-old Illinois refinery with monthly doré shipments. The client cited our on-time record (97.4 % to-the-day), our standing assay lab, and the fact that Hector personally signed the first delivery slip.

Their counter-sample policy is the reason we switched suppliers. We have not needed it in two years — but knowing it exists is the whole point.
