What is Doré Bullion? Doré bullion is a semi-pure alloy of gold and silver, usually produced at a mine site. It’s the first step in the refining process, where raw ore is melted and poured into bars. These bars are then sent to refineries for further purification. Doré bars typically contain 60-90% gold, with the rest being silver and other trace metals. This mix makes them less pure than refined gold bars but easier to transport and process. Why is it important? Doré bullion serves as a crucial link between mining operations and the global gold market. It allows miners to quickly convert extracted ore into a more manageable form, facilitating the sale and distribution of precious metals. This process not only supports the mining industry but also impacts global economies by contributing to the supply of gold and silver. Understanding doré bullion helps grasp the complexities of the precious metals market.
