TMAC Resources Inc. (TMAC) announced that commercial production was achieved on May 15 at its Doris mine and mill complex situated on the company’s Hope Bay property located in the Kitikmeot region of Nunavut, Canada.

The processing plant has operated at an average in excess of 60% of its 1,000-metric-ton-per-day (mt/d) nameplate capacity over a 45-day period, and at an average of more than 80% of capacity from May 4-15. The company continues to make improvements and optimizations to operations that will enable ramp up to steady state throughput of 1,000 mt/d. As the throughput increases, the mt of ore brought to surface from underground mining will also be increased. In addition, the company is focusing on optimizing recoveries, which have yet to reach expected levels. As improved recoveries are achieved, a transition to higher grade feed from the currently blended, lower grade stockpile ore will be fed to the processing plant.

“Achieving commercial production is a significant achievement of which our entire team is proud,” said Catharine Farrow, CEO of TMAC. “It is a great step toward achieving steady state operations at our Doris mine and mill complex, which is the first step in our plans to funding the development of the Madrid and Boston deposits.”
