In the mining sector, Vibrometric’s experience and expertise extends from Kimberlite and Nickel to Uranium and Gold.
| Borehole Seismic methods were successful in delineating kimberlite - country rock contacts at various mines, such as Finsch, Snap Lake and Diavik where Vibrometric participated in both, Seismic Survey and Data Processing.

Crosshole seismic tomography carried out in the Eastern Deeps deposit at Voisey’s Bay, Labrador, Canada succesfully detects and delineates the massive sulphide zones. With proper calibration it is possible to differentiate between disseminated, semi-massive and massive sulphide. |  Delineation of sulphide mineralization by Crosshole Tomography |
An appropriate amount of crosshole seismic surveying reduces the amount of drilling required in various stages of resource estimation. This results in significant savings in exploration expenditures. Crosshole seismic surveys conducted from surface also reduce the scope and cost of underground exploration programs.
At McArthur River mine, as a part of Cameco’s innovative and integrated multidisciplinary approach to exploration, investigations from boreholes were aimed at imaging vertical and steeply dipping structures directly related to the uranium mineralization. Downhole side-scan seismic surveys were performed in boreholes to a depth of 570m, using Vibrometric’s proprietary tool consisting of a piezoelectric, swept-impact source and a string of 24 hydrophones. The survey at McArthur River was successful in achieving its goals, by detecting diffraction and reflection patterns consistent with probable locations of mineralization.
