A bullion room in mining is a secure facility where refined precious metals, such as gold or silver, are stored, processed, and accounted for after extraction and refining. Designed with reinforced walls, locked vaults, and surveillance systems, it ensures the safe handling of these valuable resources. The room is typically restricted to authorized personnel and may also house equipment for weighing, packaging, and inspecting the metals. Bullion rooms play a critical role in safeguarding assets and ensuring compliance with legal and industry standards during the final stages of the mining and refining process.
