Well if your mum is missing its quiet a serious issue; first and foremost do not panic. Start of by registering a missing persons report with the local police station. Try contacting all your relatives and friends just to check if they have any knowledge about your mum's whereabouts. Try finding out who did she last speak too. Keep records of all the information you collect from your enquiries, so that you can offer comprehensive information, if necessary, to the authorities assisting in finding your mum.
Try placing ads in the local news paper with the complete details of your mum, like when was she last seen, what was she wearing, her age, visible birth marks if any etc, along with a full size photograph, as this will help other in identifying her.
