Cel TO DEVELOP INTER-BEREHOLE IP/RESISTIVITY FIELD TECHNIQUES FOR THE DETECTION OF OOF-HOLE MINERALISATION, AND FOR ORE-CONTINUITY STUDIES BETWEEN DRILLHOLES. TO DEVELOP A THEORETICAL FRAMEWORK FOR THE INTERPRETATION OF INTER-BOREHOLE ANOMALIES. CURRENT RESEARCH INDICATES THAT INTER-BOREHOLE IP/RESISTIVITY TECHNIQUES COULD ASSIST IN THE DETECTION OF DEEP SEATED OR LOW CONTRAST MINERAL DEPOSITS, BY VIRTUE OF THE SMALLER PROPAGATION DISTANCES AND IN SOME CASES, BY THE IMPROVED GEOMETRICAL COUPLING BETWEEN THE TARGETS' THIR DIMENSION AND THE DRILLHOLE PROFILE. DIRECTIONAL INFORMATION AND TARGET ATTITUDE, SIZE AND SHAPE MIGHT ALSO BE ESTABLISHED TO GUIDE EXPLORATORY DRILLING. IT IS PROPOSED THAT SEVERAL VARIANTS OF HOLE-TO-HOLE AND HOLE-TO-SURFACE IP/RESISTIVITY SURVEYS BE INVESTIGATED, INCLUDING A MISE A LA MASSE APPROACH TO ESTABLISH ORE-CONTINUITY BETWEEN DRILLHOLES. INTERPRETATIONAL COMPLEXITIES MAY ARISE FROM SUBSURFACE GEOMETRIC SINGULARITIES. TO OPTIMISE SURVEY DESIGN AND TO MAXIMISE THE DIAGNOSTIC DATA AVAILABLE, REFINED INTERPRETATIONAL SCHEMES WILL BE REQUIRED. ANALOGUE AND NUMERICAL MODELLING TECHNIQUES WILL BE USED TO ESTABLISH AN INTERPRETATIONAL FRAMEWORK FOR EACH OF THE HOLE-TO-HOLE, AND HOLE-TO-SURFACE ELECTRODE CONFIGURATIONS SPECIFIED. AN ATTEMPT WILL BE MADE TO EXPLOIT THE 3D NATURE OF THE OFF-HOLE TARGET ANOMALIES, BY COMBINING SURFACE AND CROOS-SECTIONAL DATA IN ISOMETRIC PRESENTATIONS. THE EXPLORATION PROBLEM WILL BE STUDIED FOR VARIOUS LEVELS OF GEOLOGICAL COMPLEXITY, INCLUDING VARIATION IN TARGET GEOMETRY, DEPTH, AND GEO-ELECTRIC CONTRASTS. MASSIVE AND DISSEMINATED SULPHIDE TARGETS WILL BE SIMULATED. FIELD EVALUATION STUDIES WILL BE UNDERTAKEN TO VERIFY THE OPERATIONAL AND INTERPRETATIONAL CRITERIA ESTABLISHED.
