Of all the major geological structures present at Copper Cliff mine, two structures are known to be seismically active: the 900 orebody cross fault, which strikes east-west and dips at about 55[degrees] north; and the Quartz Diabase Dyke (trap) located between the 100 and 900 orebodies striking east-west and dipping steeply north (Figure 2).
