Production Curtailment

Production at Smith Ranch-Highland was 67% lower for the quarter and in the first six months compared to the same periods in 2016, as a result of the decision to curtail production and defer all wellfield development at our US operations. Production is expected to continue trending down as the head grade decreases.
