and adits remained open. Several incidents are known to have occurred whereby people or animals fell down holes or became stuck in adits. These include a dog and a cow, both of which were safely recovered. Preservation The mine was listed on the South Australian Heritage Register in 1984 and was added to the now-defunct Register of the National Estate in 1996, and re-opened by then South Australian Minister for Mines, Stephen Baker MP. In 2004, tours departed from the Burnside Council Chambers with a round trip two hours in duration. Tours ran on the third Sunday of every month, and tickets cost $7 for adults and $4 for children. In 2005, the mine was closed after a rockfall event. In 2008, a bequest of $30,000 AUD was given to the City of Burnside Council in trust, to facilitate repairs and make it possible to reopen the mine for tours. The late donor, John Clark, had previously facilitated tours of the mine from 1986, and appeared in an episode of the TV series Postcards which was dedicated to the Glen Osmond mines, and presented by Keith Conlon. In 2008, Ross Both and Greg Drew wrote of the Glen Osmond mines in the Journal of Australasian Mining History: "It is essential that further restoration of the [Wheal Watkins] adits be carried out so that public access will again be possible to one of Australia's most significant mining heritage sites." In 2013, Mayor David Parkin stated that "ratepayers have outlaid considerable funds on preservation of these mines over the years and it is a matter of judgment when enough is enough." As of March 2016, the mine remains closed to the public. The Burnside Historical Society plans to work with the council to reopen the mine for tours and develop a display for public viewing which will feature a pick found in the Glen Osmond mine and a piece of galena.
