Info

Prior to that, more than 40 different types of tenements could be applied for under the original Act of 1904. At the end of 1985, more than 35000 tenement applications under the 1978 act had been lodged in the Department and approximately 394000 under the 1904 act. Each tenement may have up to 70 items of information related to it, such as the name and address of the holder, Departmental file number, area, plan name and other legal dealing attributes. Since the beginning of this century and until recently all tenement information was recorded by hand in large leather bound volumes. Because of the vastness and remoteness of Western Australia, a system of registration offices was established in remote areas where tenement applications may be lodged in the field to avoid the long trip to Head Office in Perth, capital city of Western Australia. (See Fig 3) A duplicate set of registers is kept in each outstation covering tenement applications in that particular region. All tenements are plotted onto plans at various scales although mostly at 1:50 000 and a duplicate set of plans is maintained in each outstation similar to the registers. The Department is required to service the public and the mining industry by providing up to date information on all aspects of current applications and in particular, evidence that ground is available for pegging. The massive amount of information requiring recording, plotting and processing has severely strained the ability of the Department to maintain manual systems. In 1981/82 investigations were carried out into ways of computerising the information so that more efficient methods of recording and processing the tenement data would enable a better service to be provided to the industry and the Department. When an application for a mining tenement is lodged, it is allocated a file number and a tenement number. The State is divided into Mineral Fields for the purpose of administration and as the names are quite long a 2 digit code is used to precede the tenement member. Thus, a tenement applied for as an Exploration Licence in the Marble Bar District would carry a number like this - E 80 3962. 89
