The present till now practice of averaging of ore by metal content at mining-dressing enterprises does not allow evaluating objectively really existing regularities of dressing process. The processing of large statistical data by specially designed methods has revealed the relationships of extracted mass of metals into concentrates when processing of ore at preparation plants. The analysis of the obtained relationships points to necessity of timely control by flows of ore with due account of different sorts of metal. For this problem solving it is offered to use specially designed methods on carrying out of calendar planning of a mining and shipment of ore at open casts, based on ranked arriving of flows of different sorts ores to preparation plant. The given methods includes economic-mathematical model forming and its implementing by worked out method. The formed model allows taking into account different technological and organisation limits, typical operation conditions of open cast and preparation plants. Using this methods of control of mining operations and designed on its basis the complex of software allows increasing volume of metals, extracting into concentrate, up to two per cent without any additional costs and saving of the existing technological schemes at preparation plant.

This contribution summarises new knowledge and data, obtained during a three year ARCAMIRA funded research project, on the mineralogical and geochemical characteristics of hydrothermal alteration associated with low sulfidation, gold-silver epithermal deposits. These data are used to develop exploration vectors for use at both deposit and district scales, plus techniques have been established to distinguish ore grade epithermal systems from barren or low grade systems. Deposits investigated were Ladolam, Papua New Guinea, Gosowong and Mt Muro, Indonesia, Cerro Vaguardia, Argentina and Bimurra and Twin Hills, Australia.
