Thank you, Paul. On Slide 5, we show operating highlights at Mount Milligan for the quarter. The Mount Milligan mine produced over 40,000 ounces of gold and almost 20 million pounds of copper in the fourth quarter, achieving 2023 production guidance ranges for both gold and copper. For 2023, Mount Milligan achieved annual records for total tonnes mined and plant throughput at over 50 million tonnes mined and 21.7 million tonnes processed, respectively. Looking ahead, in 2024, we expect Mount Milligan to produce 180,000 to 200,000 ounces of payable gold, which is 23% higher than last year, mainly due to mine sequencing and higher gold grade. 2024 payable copper production is expected to be between 55 million to 65 million pounds. Both gold and copper production are expected to be evenly weighted throughout the year, but sales in the second half of 2024 are expected to contribute approximately 55% of the annual sales. In the fourth quarter, gold production costs were $946 per ounce and all-in sustaining costs on a by-product basis were $946 per ounce. Full year 2023 gold production cost at Mount Milligan were $1,088 per ounce, which was in line with the guidance range. Full year all-in sustaining costs were $1,156 per ounce, beating the guidance range. Looking ahead, Mount Milligan's 2024 all-in sustaining costs are expected to be $1,075 to $1,175 per ounce. In the fourth quarter, we embarked on a site-wide optimization program at Mount Milligan focused on an integrated holistic assessment of occupation and health and safety, mine and plant operations. We are encouraged by the preliminary cash flow improvement estimates from the first phase of work on this program, and we expect to start realizing the benefits of the program later this year. As a result, the potential cost savings are not included in the Mount Milligan's 2024 cost guidance ranges. On Slide 6, as Paul mentioned earlier, we are assessing Mount Milligan's potential to be a multi-decade operation. We now have 250 million tonnes of reserves at Mount Milligan, extending our mine life out to 2035. In addition, we have substantially increased our resource to 260 million tonnes, most of which is classified as measured or indicated. And lastly, we have additional drilled inventory, which has not been incorporated into the resources, where we intend to continue drilling with the objective of further increases to the resources. We intend to incorporate these additional resources into an optimized mine plan in support of a preliminary economic assessment. On Slide 7, to provide more detail, we are targeting deposits to the west and southwest of the main pit within the current mining lease. At Goldmark and South Boundary, there are possibilities for near surface additions. At North Slope, DWBX and Saddle West, we continue to test for depth extension. And finally, I commend the Mount Milligan site team for embracing the site optimization program. The team has been fully engaged and is dedicated to enhancing the culture for continuous improvement through this important initiative. To date, we started to see evidence of this continually improved safety performance in the fourth quarter and year-to-date. On Slide 8 are the operating highlights at Öksüt. Öksüt closed out the year with a second consecutive quarter of strong performance. Fourth quarter production was over 88,000 ounces and full year production was almost 196,000 ounces, achieving the midpoint of the guidance range. Production guidance for 2024 at Öksüt is estimated to be 190,000 to 210,000 ounces of gold, which is aligned with our previously disclosed life of mine plan published last September. As we are still going through the buildup of inventory, approximately 60% of the annual production is expected to be weighted to the first half of this year. Gold production costs and all-in sustaining costs on a by-product basis in the fourth quarter of 2023 were $474 per ounce and $671 per ounce, respectively. Full year 2023 gold production costs and all-in sustaining costs were $457 per ounce and $675 per ounce, respectively, in line with the guidance ranges. Looking ahead, 2024 gold production cost guidance is expected to be $650 to $750 per ounce and all-in sustaining cost guidance is expected to be $900 to $1,000 per ounce. Costs in 2024 at Öksüt are expected to be higher than previously disclosed in the life of mine plan due to a new multiyear contract with the existing mining and hauling service provider as well as higher weighted average cost per ounce in the remaining inventory. To wrap up, I'd like to commend the Öksüt team for outperforming their 2023 safety targets and achieving one year without a lost time injury in early December. This milestone demonstrates our priority to the safety of our workforce and our commitment to the journey towards achieving zero harm. I'll now pass on to Darren to walk through our financial highlights for the quarter.
