Ribago

Canada
Voici comment les levés EM dans le domaine du temps permettent de minimiser les coûts en exploration en maximisant l’aire de la sous-surface explorée pour chaque trou foré.
 

The Ribago VMS deposit is located in the Noranda Mining Camp of northern Quebec, Canada.

The deposit is at a depth of 600 metres.

A borehole TDEM survey shows an off-hole response from sulphides located 150 metres west of the hole.

This demonstrates that TDEM greatly expands the volume of the subsurface that can be investigated by a borehole.
