Abstract: High resolution resistivity/IP (HRRIP) surveys were carried out over nine mineral deposits within Yukon. The objectives of this study were 1) to investigate whether HRRIP surveys could map mineralization and structure associated with known deposits, and 2) to determine which arrays, if any, were the most diagnostic for a given deposit type. The study included a copper porphyry deposit, a lead-zinc-silver vein deposit, and several different styles of gold mineralization/deposits. The location of the HRRIP line(s) were chosen based on the known mineralization and geology of the deposit. On average 3 different arrays were carried out along each line. Variations of dipole-dipole, inverse Schlumberger and pole-dipole arrays, as well as an array developed by Advanced Geosciences Inc. of Austin, Texas were used. Two-dimensional inversions of each array for each line were carried out to produce 2D resistivity and IP cross sections. These sections provided the fundamental information for the study.

The deposits used in this report are Brewery Creek, Dublin Gulch, Flame and Moth, Klaza, Charlotte, Coffee, QV, Golden Saddle, and Williams South.
