The format of most existing metallogenic maps is not adequate for scales of 1:500 000 or less. The major problem is the colourful out-of-scale locality symbols, which mask the map detail in the most important areas, the immediate vicinity of the ore occurrences. The design of the symbols is also a problem, most being influenced considerably by genetic interpretations that are subjective and change with time; they are incapable of expressing transitionality, correlation of metallogenetic and lithogenetic events, and they cannot accommodate incomplete information. A substantially different philosophy of metallogenic mapping has been tested using the Pine Creek Geosyncline as an example. Ideally, the product would be a set of three matching maps. Map 1 would be a base map, a modified geological map that consistently shows the age of units by colour and the lithology of units by pattern, regardless of genesis and the level of emplacement. Mineralised occurrences would be identified in the simplest way possible, so as not to obscure the background information. Map 2 would be a gitological map, or map of mineral deposits, providing information on the geological properties of occurrences. The symbols suggested are based on simplified geological cross-sections, and are colour and pattern coordinated with the base map, to give the reader an immediate impression about the contemporaneity of rock-and ore-forming events and of the hosts to the ore. Within the symbol framework for a given mineralisation style, a wide range of properties of individual occurrences can be shown, and unknown information can be truthfully expressed as a blank component of the symbol. Map 3 would be a commodity map, showing the ore metals, their individual and total accumulations, and the concentration of the major metal.
