Thank you, Paul. On slide five, we show operating highlights at Mount Milligan for the quarter. The Mount Milligan mine produced over 39,000 ounces of gold in the third quarter in line with last quarter and produced 15 million pounds of copper, almost 10% higher than the last quarter. There was some residual or waste transition zone material mine in the third quarter and recoveries were impacted by the elevated ratio of pyrite to chalcopyrite. We expect medium term recoveries for gold and copper to be similar to those achieved in 2023 and have been undertaking additional metallurgical reviews with a goal of increasing recoveries from current levels to better manage this part of the ore body. Our Mount Milligan production guidance for 2023 has been adjusted due to lower than planned gold recovery from the elevated pyrite to chalcopyrite ratios and lower production experience in the first half of the year due to mine sequencing. We are now expecting gold production at Mount Milligan to be between 150,000 and 160,000 ounces down slightly from the low end of the 160,000 to 170,000 ounces announced previously. Our copper production guidance remains at 60 million to 70 million pounds, and is expected to be near the low end of this range. In the third quarter, gold production costs were $1,050 per ounce, and all-in sustaining costs on a by-product basis were $1,150 per ounce, 16% and 28% lower than last quarter, respectively. All-in sustaining costs were lower quarter-over-quarter due to higher gold ounces sold, lower gold production cost per ounce and higher by-product credits as a result of high copper sales. As a result of the revised gold production outlook for Mount Milligan, we have increased its full year 2023 gold production costs and all-in sustaining cost guidance. Gold production costs for the full year are now expected to be between $1,050 and $1,100 per ounce, and all-in sustaining cost guidance is now expected to be $1,175 to $1,225 per ounce. A comprehensive asset optimization review has been launched, which includes safety, productivity, and cost efficiencies in concert with mine plan optimization. This review is expected to be completed in 2024 and drive incremental improvements in operations. Finally, we congratulate our Mount Milligan team and partners at Chu Cho Environmental for receiving the BC Mine Reclamation Award for Outstanding Reclamation Achievement in 2023. This award recognizes the ongoing research into innovative techniques to help achieve eventual reclamation and land use objectives at the Mount Milligan Mine in collaboration with local communities. On slide six are the operating highlights at Oksut. Third quarter production was over 86,000 ounces, which exceeded our expectations during the ramp up of operations. As of late September, all of the stored gold and carbon inventory had been processed. The mine continues to have elevated levels of recoverable ounces of gold in ore stockpiles, and on the heap leach pad, which are expected to be processed in the coming months. Due to the operating team's successful ramp up execution in the third quarter, full year 2023 production guidance at Oksut has been increased to 190,000 to 200,000 ounces of gold. Gold production costs and all-in sustaining costs on a by-product basis in the third quarter 2023 were $445 per ounce and $582 per ounce, respectively, due to accruals from inventory buildup. As a result of the increased gold production outlook at Oksut, we are lowering our gold production cost and all-in sustaining cost guidance for 2023. We now expect full year gold production costs to be in the range of $425 to $475 per ounce, and all-in sustaining cost to be in the range of $625 to $675 per ounce. To wrap up, I'd like to command the Oksut team for achieving 2 million work hours without a lost time injury in September. The safety of our employees and contractors is our top priority, and this milestone demonstrates our commitment to a zero harm culture. I'll now pass it to Darren to walk through our financial highlights for the quarter.
