Copper Mountain Announces Q3 2018 Production Results

Production for the third quarter 2018 was 18.3 million pounds of copper, 7,500 ounces of gold and 64,900 ounces of silver, which was in line with expectations. The Company guided that third quarter 2018 copper production would be approximately 10% lower than the second quarter due to lower copper grades being mined. Actual copper production was 8.5% lower than the second quarter. Fourth quarter copper production is expected to be the strongest quarter of 2018.  The Company remains on track to achieve 2018 annual production guidance of 80 million pounds of copper (+/-5%).

Copper equivalent production was 22.0 million pounds and was down only 4.8% compared to the second quarter due to higher gold production as a result of increased gold grade and recovery after the installation of a flash flotation circuit in the concentrator.

The mine continued with the next pushback on Pit#2 west, which commenced in the second quarter. The strip ratio in the third quarter was 2.3 to 1, lower than the second quarter.  Mill throughput averaged 41,300 tonnes per day, with copper recovery of 79.1% and average feed grade of 0.28% copper.  Grade was lower in the third quarter but was as guided and in line with the mine plan.

“Copper Mountain Mine operated on plan and as expected this quarter,” commented Gil Clausen, Copper Mountain’s President and CEO. The fourth quarter will be our strongest quarter this year and we are on track to achieve our production guidance.  Copper Mountain continues to demonstrate predictability and consistency.”
