Bingham Canyon Mine Visitors Center will not open in 2013

Observed slope movement will delay opening until 2014

South Jordan, Utah (April 1, 2013) – Due to slope movement of the northeast wall at Kennecott Utah Copper’s Bingham Canyon Mine over the winter, the Visitors Center and overlook plaza will not reopen as scheduled on April 1. Plans are underway to provide an educational opportunity for Utahns and tourists in 2014.

“Slope movement is an infrequent but expected occurrence in mining operations and is carefully monitored,” said Bingham Canyon Mine General Manager Matt Lengerich. “We are proactively addressing any potential safety issues by not opening the Visitors Center this year. We look forward to offering an experience that demonstrates the importance of mining and our commitment to the environment and community next year.”

Since 1992, the Bingham Canyon Mine Visitors Center has generated $2.8 million dollars for its charitable foundation, welcomed more than 3 million visitors and provided a unique experience to learn more about mining and how it benefits our everyday lives.
