Tahoe Resources Inc. reports a commissioning incident at its Shahuindo mine in Peru. At 1am on Saturday 10 February 2018, a leak was identified in the barren solution pipeline in the overland conveyer containment channel that connects to the agglomeration areas storage tank. The pipeline had been commissioned and pressure tested, but was not yet in operation.
Immediately after identifying the leak, the company shut down all commissioning of the crushing and agglomeration circuit, focussed on containment, and reported the incident to the Agency for Environmental Assessment and Control (OEFA) within the required 24-hour period. All commissioning of the crushing and agglomeration circuit has been temporarily suspended until a thorough investigation is completed, the issue is resolved and the pipeline is fully repaired. At this time, the company does not anticipate a significant impact to production.
Following its preliminary internal investigation, the company determined that the engineered containment systems in place were successful and the leak was contained within the property boundaries.
The company is in the process of engaging and communicating with nearby communities and will keep them informed. The company does not believe there is any risk of contamination to the nearby communities, livestock, environment or our employees.
This incident is an isolated event related to the barren solution pipeline in the overland conveyer containment channel. According to the company, the storm water pond and solution ponds continue to perform as designed and are successfully diverting all storm water away from the industrial sites during this rainy season.
