King Edward Mine is the most complete set of mine buildings from the 1900 period. Sheet metal and wooden buildings contain a tin dressing plant including the last working Californian Stamps in Britain, driven by a horizontal engine. Also there are working examples of round frames, rag frames and a Cornish buddle.

There is a small museum located in the old mill engine room and a lecture theatre showing a film of the plant working. Currently underground access is not available. But there are guided tours through the restored tin processing plant. Some items of the machinery can be seen working. There is a Mineral Tramways exhibition can be seen in the old calciner.

The site is used by the Camborne School of Mines (CSM) as experimental mine for its students. When the King Edward Mine was flooded in 1921, the Camborne School of Mines moved their underground training to Great Condurrow mine nearby. This mine is only a few hundred yards up the hill and it is hoped to run quality underground visits there some time in the future.

During the Covid lockdown the volunteers overhauled machinery and some now operable for the first time. A new space has been made to display materials from Holman’s Engineering, a Camborne company which produced many items for mining. The survey office was outfitted with retro lighting and is almost in the same state it was built in 1897. An exhibition of surveying instruments and equipment was added. The blacksmith’s forge was restored and is now in a working state, in the future it will be operated by a blacksmith on special occasions. The Croust Hut, which is used as a cafe, was improved and offers snacks, lunch, and coffee.
