Gold Assaying at GWIC: Why Accurate Purity Testing Is the Foundation of Every Gold Transaction

In the gold trade, everything is built on one foundational truth: you must know exactly what you have. A gold bar claimed to be 99.9% pure but actually containing 92% gold represents a significant financial fraud. A doré batch estimated by eye at 300 grams of gold content that actually holds 210 grams means a miner is being dramatically underpaid for their work.

Assaying — the scientific determination of the precise metal content in a sample — is the technology that makes honest gold trading possible. At GWIC Gold Refinery & Pharmaceutical, our assaying laboratory is the technical heart of our entire operation.
