Vein deposits are mineral formations that occur when minerals fill cracks or fractures in rocks. These deposits often contain valuable metals like gold, silver, or copper, which are formed through geological processes over time. The minerals crystallize as hot fluids move through the cracks, leading to concentrated areas of valuable resources. These deposits are typically found in mountainous regions and are often mined through techniques like hard rock mining. The extraction process can be complex, requiring careful planning to ensure safety and efficiency while minimizing environmental impact. Vein deposits are an important source of minerals for various industries.
