Ray Beer was an employee of the Central Deborah Gold Mine. February 15th 2009: Bendigo Advertiser: 'MINING stalwart Raymond Beer has died at the age of 74 after a battle with cancer. He leaves behind an extended family and a legacy in Bendigo’s mining history. Ray was mine manager at the Central Deborah Gold Mine - appointed in 1978 - and led the team that made possible the underground project at the second level. He had a vision to allow visitors to go underground and experience Bendigo’s mining heritage first hand. Ray was responsible for developing the new battery, shaft and poppet head to make this a reality. It took persistence and lots of hard work. Friend and work colleague Bill McNamara said Ray was as good as 10 men. His enthusiasm and work ethic were unprecedented. Ray will be sadly missed by his wife, Thelma, six children, 15 grandchildren, seven brothers, three sisters, his extended family, and friends. He will be remembered for his kindness, tenacity and strength of character. In recognition of his contribution to Bendigo’s mining history, after more than 20 years of service at his retirement, a bronze life-sized statue was unveiled in his honour'. Central Deborah Gold Mine history: At its peak, Central Deborah Gold Mine reached a depth of 412 metres. It has 17 separate levels and 15 kilometres of drives and cross cuts (tunnels). The Central Deborah was very much a hands-on mine and the conditions that the miners worked in would be considered shocking by today's standards – being lowered underground in a cage with only two sides, often working ankle to knee deep in water, filling up to 32 ore trucks a shift by hand which were then pushed a mile or more along rails in the drives, working by carbide lamp, breathing in the fumes and rock dust and communication by bells. Geez, they were ironmen. However, at the time working conditions were considered to be among the best on the goldfields at Central Deborah, after all it was one of the only mines that had hot showers. Following Central Deborah Gold Mine's closure, the Bendigo skyline began to noticeably change. Obvious remnants of mining such as poppet heads, engine rooms, service quarters, battery houses and chimneys were steadily disappearing. After intense lobbying by the local community, the Bendigo City Council purchased the still very much intact Central Deborah Gold Mine in 1970 for a mere $6,000 to ensure that a vital link to Bendigo's historic golden past was maintained. The Bendigo Trust was then formed to oversee the operations of the Central Deborah Gold Mine, which led to the surface of the mine being opened to the public in 1971. Initially the surface was open for just 12 hours a week and as the demand for viewing a part of Bendigo's history increased, so did the opening hours. In 1974 the mine was gazetted as a Public Historical Purposes Reserve and attracted such visitors as H.R.H Prince Charles. By far the greatest shortcoming at this stage was that no one could view the underground workings, as these had become flooded. After what could only be described as a monumental effort by everyone involved, Level 2 of the mine was officially opened to the public by the Premier of Victoria, the Honourable John Cain, on 20 June 1986, which brought to fruition a long standing dream.Black and white photograph.

This style of mask was developed in Britain and began to appear from the 1930s, though original models may have been produced in the 1920s. Various patents for this style of mask were still being filed in the 1960s, so they were used for a considerable period of time. It is possible that the original filter pads for these masks contained asbestos, as they supposedly utilised 'fire proof' materials. Asbestos was already in use in other British respirator masks at this time. Original cataloguing information believed this item to be an eye shield, but further research has indicated that this is not the case.Mask consists of a metal plate designed to cover the lower half of the face. There is a recess along the top edge of the plate designed for the nose to sit in. There is a large oblong opening with rounded corners at the centre of the mask, which is a mouth opening to assist speech and is the main air intake. There are five round holes on either side of the mask, likely included to decrease the mask's breathing resistance for the wearer. Rounded slots at each edge of the mask are threaded through with an elastic strap, used for attaching the mask to the face. This mask would have been used with a filtering pad attached, but the pad is missing.
