The Powered Mine is a premium building added on October 5th. Like the Mine, the Powered Mine collects metal automatically over time and stores it inside. The metal collected by the Powered Mine is stored within the building and can be collected and added to your total available metal stockpile by clicking on the Powered Mine once it has some metal stored. Metal collects more slowly than wood. Upgrading the Powerered Mine increases its production rate and local storage capacity.
This building is available for 19 Pramin, and has it's own building cap of 8, seperate from the Mine.
