2D/3D Multicomponent Seismic Imaging In the Flin Flon Mining Camp, Canada

A comprehensive seismic program has been conducted within the Flin Flon VMS mining camp in northern Manitoba and Saskatchewan, Canada. Assessment of the reflectivity of rocks within the camp using rock property measurements and in situ downhole geophysical logging demonstrates that significant variations in acoustic impedance exist amongst rocks from the camp. Specifically, reflections should occur from contacts of rhyolites (which constitute the primary ore-bearing horizon) and mafic volcanic/intrusive rocks (gabbros or basalts), from sulphide occurrences, from shear zones in the mafic rocks, and from contacts between the metasedimentary rocks (Missi Group) and metavolcanics. 2D and 3D multi-component seismic images appear to map the “mine horizon” at depth and demonstrate structural repetition that may be favourable for exploration for blind deposits. A strong reflection/scattering response is observed in the vicinity of the existing ore deposits providing a guide for identifying new exploration drill targets.
