Hudbay has filed an updated National Instruments 43-01 technical report in respect to its Constancia Mine in Peru. The 2016 Technical Report includes updates of the mine plan, reserves and resources, throughput and capital and operating costs for the remaining life of the mine.
The mine plan incorporates the high grade Pampacancha satellite deposit and contemplates average annual production of 110 thousand tonnes of copper in concentrate over the next five years. Mining of Pampacancha is planned to begin in 2018 with total project capital costs estimated at 54 million dollars. The report states contained copper in reserves increased by 34 percent from 2017 through the end of mine life compared to the 2012 technical report reflecting the previously reported increase in Constancia reserve tonnage.
