Plans were passed to Mineral Resources Tasmania in 1999 by a member of the public who found them in a building in Bathurst Street when it was being demolished. While MRT felt they had probably originated from the mine office they decided to retain all the underground mine plans for future use. The remainder were passed to Archives.
Plans for construction of facilities at Magnet Silver Mining Co. N. L. Includes plans of the mill, machinery, the mines' water supply, eletricity and tramway.
These records are part of the holdings of the Tasmanian Archives
