Q3 2017 Update

Production Curtailment

Total US production was nominal for the quarter and 70% lower for the first nine 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.

As expected, production continues to trend down as the head grade decreases. Given production volumes to the end of September, we have lowered our 2017 production plan by 0.1 million pounds to 0.3 million pounds.
