Description
The Assay Office, now used as a store, is located approximately 20 meters southwest of the Count House at King Edward Mine. It was likely built in the late 19th century and has undergone some alterations. The building features a weather-boarded east front and south end, while the rest is constructed of uncoursed rubble with a corrugated sheet roof. It is a small, single-storey structure with three bays. The first bay has double garage doors, the second and third bays have doorways, and there is a two-light window between them, which is partially boarded. Additionally, there is a fixed 8-pane window in the third bay and a cut-down chimney on the ridge at the junction of the second and third bays. A small opening is present in the rear wall. The interior has not been inspected. This building is part of a uniquely complete set of turn-of-the-century mine buildings on the site.
