Gold deposits are natural accumulations of the metal gold found in the Earth's crust. These deposits can occur in various forms, including placer deposits, which are formed by the erosion of rocks containing gold, and lode deposits, where gold is found in solid rock. Mining companies often explore these deposits to extract gold for use in jewelry, electronics, and as an investment. The process of locating and extracting gold involves geological surveys and various mining techniques, ensuring that the valuable resource is obtained efficiently and sustainably.
