GRC was founded in 1975 by Dick Spera who believed that if you provide customers with outstanding service and fair rates you would develop a loyal following. He was right. Thousands upon thousands of clients later, GRC continues to provide excellence in the field of refining.
Our analytical division began as a simple fire assay office for the refinery. We expanded our lab to offer a variety of services to the trade including fire assay for precious metals, determination of gold, silver, platinum, and palladium in sweeps, bullions, and solutions. Over 35 years later, we are proud of our reputation for excellence. Our facility located in Long Island, NY serves a diverse clientele with precious metal refining needs.
We process high-grade polishings, bullion, and other high yielding materials to a finished product…and we invite you to watch the process! You are always welcome to visit our facility to watch your material being processed and sampled.
