2018 Q3 Update

US ISR Operations

As a result of the decision to curtail production and defer all wellfield development at our US operations, there was no production in the third quarter. We have now effectively ceased production, which is expected to result in production of about 100,000 pounds for the year. As long as production is suspended, we expect ongoing cash and non-cash care and maintenance costs to range between $11 million (US) and $13 million (US) annually for the first few years (previously $18 million (US) and $22 million (US) which reflected care and maintenance costs prior to full cessation of production).

On September 30, the Nuclear Regulatory Commission approved a 10-year renewal of the operating licence for Smith Ranch-Highland. The licence is valid until September 30, 2028.
