Abstract

We have studied scaling behavior of velocity, density and acoustic impedance down-hole logs from an approximately 850 m deep hole in the Brunswick No. 6 area. Power spectrum of all the logs indicates that measured properties exhibit scaling behaviour and suggests that lithological variation is a major contributor to observed scaling behaviour. We have also analyzed and processed an about 38-km non-orthogonal 3D surface reflection seismic data from the Brunswick No. 6 area, to provide 3D information about the main geological structures hosting the mineralization. The 3D data was processed using a prestack DMO and poststack migration algorithm with special focus to refraction static corrections, velocity analysis and DMO corrections that are very important for the data recorded in crystalline environment. The processing results indicate that the highly prospective and mineralized Brunswick horizon is part of a continuous reflective package that extends down to at least a depth of about 4-5 km. The reflectivity character can be used to guide future deep mineral exploration in this mining camp.
