TENDEX: A COMPUTERISED DATA BASE OF MINING TENEMENT INFORMATION D T PEARCE, ASSISTANT DIRECTOR, SURVEYS & MAPPING DEPARTMENT OF MINES MINERAL HOUSE 66 ADELAIDE TERRACE PERTH WESTERN AUSTRALIA ABSTRACT The Department of Mines in Western Australia is responsible for the registration and processing of application for mining tenements. In a period of reasonable mining interest and activity, the number of applications lodged in the Department are in excess of 10,000 per year, rising to between 60,000-80,000 in a boom year. Tendex is a computerised data base holding the most important attribute data against approximately 35,000 tenements. It was designed as the first step in a building block approach to an eventual large data base managment system of tenement information, and scientific data connected to a geographic base. This paper outlines the philosophy, method and results of the Tendex system. IMPORTANCE OF MINING TO THE STATE The importance of mining to the economic well being of Western Australia can be gauged from the fact that in 1984 the value of minerals extracted was almost $4.7 billion (Aus) of which the Government collected more than $180 million in royalties, rent and fees. (See Fig 1) The Western Australian Mining industry contributed 30% of the total value of overseas trade for Australia and more than 80% of the value of W.A. mineral production is exported. (See Fig 2) There are currently 5 different types of tenement that maybe applied for to carry out exploration and mining under a new Act introduced in 1978. EL - Exploration lease ML - Mineral lease PL - Prospecting licence GPL - General purpose lease ML - Miscellaneous licence 86
