Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. As part of the methodology project of the TGI-4 program, the Geological Survey of Canada acquired a 3D-3C seismic data set over the Lalor Lake VMS deposit, located near Snow Lake Manitoba. The Lalor Lake VMS deposit was chosen as a test site as it provided an intact, well-characterized 27 Mt deep ore deposit with a rich catalog of geological and geophysical data. The 3D-3C seismic data was acquired to develop and test seismic imaging methods for the deep exploration of VMS deposit. We described the field acquisition parameters and the main parameters used for the processing of the data. The processing focussed on P-wave data recorded on the vertical receiver component. The P-wave data reveals many reflections at shallow depth and remarkably continuous reflections close to the base of the Chisel sequence.
