Notable Quotes

• "We are very pleased with progress this winter. The installation of the winter road is an important part of our operations. Cold weather with limited snow is creating thick ice, enabling faster and stronger roads to be constructed. Our plans are to get the mill operating as expeditiously as possible." — Dave Webb, President and CEO
