CARLIN — A slide at the Gold Quarry open pit mine led Newmont Mining Corp. to suspend operations at the site earlier this month.
Localized ground movement occurred on the on the pit’s southwest wall on Oct. 5, and the company is evaluating the event.
No one was harmed as a result of the slide, and the Mine Safety and Health Administration and State of Nevada were notified after the event, the company stated.
“Newmont is working closely with regulatory agencies to evaluate the slide and develop a remediation plan that will allow for the safe resumption of operations in that portion of the pit,” the company wrote in an email to the Elko Daily Free Press. “Processing and other operations at Newmont’s Carlin complex are continuing uninterrupted.”
Employees working in the Gold Quarry pit have been reassigned to other areas of the Carlin operations, and as an added safety precaution, personnel from the Chukar underground mine at the bottom of the pit were relocated to the surface.
Newmont also is working with underground mining contractor Small Mine Development, which operates Chukar, to evaluation options for recommencing mining, the company stated.
Timing to recommence activities at the Gold Quarry pit and Chukar underground will not be confirmed until technical assessments have been completed, Newmont stated.
Gold Quarry is one of three open pits in Newmont’s Carlin operations. The operation also includes four underground mines.
Newmont also operates the Phoenix open pit mine near Battle Mountain, the Twin Creeks mine and Turquoise Ridge Joint Venture northeast of Winnemucca, and Long Canyon open pit mine outside of Wells. Newmont is a leading gold and copper producer with operations primarily in the United States — including Nevada and Colorado — Australia, Ghana, Peru and Suriname. The company has been publicly traded since 1925.
