Kennecott Utah Copper prepares for a slide in the Bingham Canyon Mine

South Jordan, Utah (April 10, 2013) ­– Kennecott Utah Copper continues to closely monitor ground movement in the northeast wall of the Bingham Canyon Mine in anticipation of a slide. Kennecott has observed increasing ground movement and taken the following steps to ensure safety and reduce impacts to the operation:

Ensure employee safety by restricting access to areas of concern and relocating employees to other areas within the mine.
Reduce impacts to the operation by relocating utilities, buildings, roads and heavy machinery to maintain long-term productivity in areas not impacted by the slide.
Maintain communication with employees and community stakeholders to share information about proactive contingency planning measures.
The anticipated slide will be contained within the Bingham Canyon Mine; however, visible dust may result from the slide. We are not currently able to assess the size or exact timing of the slide.
