THE METHODOLOGY PRESENTED IN THE PH.D. THESIS PROVIDES THE MEANS OF DEFINING THE EFFECT OF THE RESERVE ESTIMATION ERROR ON THE DESIRABILITY OF MINING A DEPOSIT. IT IS KNOWN THAT MINERAL RESERVES CAN BE CLASSIFIED ACCORDING TO THE DEGREE OF GEOLOGICAL ASSURANCE, WHICH IS BEST EXPRESSED BY THE ABOVE-MENTION ESTIMATION ERROR (CLASS A, B, ETC). IN CASE OF EXPLORING A CERTAIN DEPOSIT WITH VARYING DENSITY, THE VARIOUS DEPOSIT SECTIONS (WITH THE SAME EXPLORATION DENSITY CAN BECLASSIFIED IN DIFFERENT CLASSES AND EACH ONE OF THEM (EACH CLASS) HAS A DIFFERENT VALUE (DESIRABILITY OF MINING) FOR THE DECISION MAKER. THIS VALUE IS AFFECTED BY THE RISK DUE TO THE INSUFFICIENT KNOWLEDGE OF THE GEOLOGICAL PARAMETERS. THE METHODOLOGY DEVELOPED HERE IS BASED UPON THE MODELS OF FINANCIAL ANALYSIS (RISK ANALYSIS, CAPITAL MARKET THEORY, UTILITY THEORY). THIS METHODOLOGY, USING AS INPUT DATA THE PREVAILING CONDITIONS IN THE CAPITAL MARKET, THE SYSTEMATIC RISK OF THE MINING INVESTMENT, THE INVESTMENT COST IN ...
