... the GEMTIP model in conjunction with an integral equation-based modeling and inversion code. This code can replicate all inductive coupling and EM effects, which removes one large barrier to inversion of large bandwidth spectral IP data. The results of this inversion were interpreted, and several drill holes...

... problems where sharp boundaries are expected. The common use of a drill hole to build a reference model is improved upon in this work by extending blocky geologic data to the entire model with a 1 norm. A new composite least-squares and minimum gradient support regularization is introduced and shown...

... parallel lines, each line approximately 20 km long with an intra-line spacing of approximately 1.5 km. A nominal station spacing of 250 m was used with infill stations collected at 125 m spacing where warranted (Figure 3).

... separation pole-dipole Induced Polarization (IP) on five lines covering the favorable Cuitaca granodiorite. The results showed many strong IP responses, clearly due to high levels of disseminated pyrite. In spite of many other strong IP results, the first drill hole M-1 was collared on a breccia zone forming...

... drill hole and seismic information to allow assessment of the geomechanical environment. We demonstrate our approach using results from a 3D and a 2D seismic survey. We introduce a means of converting acoustic impedance to the Geophysical Strata Rating (GSR). The GSR is a rock mass rating scheme...
