Computers in mineral exploration: Some uses, limitations, and requirements

Abstract

Essential requirements for the use of computers in mineral exploration are: (1) an adaptable storage-retrieval system, (2) adequate data files, (3) a minimum establishment in terms of staff and organization, (4) integration of computer filing systems with paper filing systems so that they complement one another, and (5) understanding by users of the application of computer techniques to geological information. Data files applicable to mineral exploration fall into three categories: Field-Data files, Bibliographic-Index files, and Mineral-Deposit files. An increasing proportion of data files used by exploration companies will be acquired from government organizations and service agencies. Computer techniques must be used selectively. They become more applicable as: (1) projects last longer, (2) the amount of exploration work per unit area increases, and (3) the amount of previously generated information becomes greater. Limitations include: (1) nonapplicability of computer techniques to some types of exploration, (2) expense of file creation, (3) short-time span of many exploration projects, and (4) need to maintain a balance between a computer facility and the exploration department it is designed to serve. Causes of disappointment include preoccupation with statistical techniques at the expense of storage and retrieval, the nonselective application of computers, and failure to attain a minimum organizational establishment. Although individual computer-based approaches may lead directly to exploration targets which would not have been detected without computers, the essential advantage of a computer facility lies in its ability to improve the performance of each exploration geologist by increasing the quantity and quality of available data.
