Thanks, Mitch. Across our whole asset portfolio, we see a great track record of excellence including long-term trusted relationships with our key stakeholders that allow us to continue to develop our mines and secure key permits like the recent Boston Expansion success at Wharf, providing great opportunities for further growth within our operating footprints. Getting into quarterly operating details on Slide six and starting with Palmarejo. Goods, silver and gold grades led to solid production for the quarter, with the team overcoming a four-day power outage due to wildfires. On the cost side, the strengthening peso continued to create pressure, resulting in approximately $5 million of additional costs. Moving on to Rochester. Better than anticipated production was driven by continued positive residual ounce production from legacy leach pads with the majority of ore placement now occurring on the new Pad 6, gold and silver production decreased as expected compared to the first quarter. Production rates will remain depressed during this transition period until first solution through the metal core plant is processed next month. Looking ahead, we expect the cushion we built up during Rochester strong first half performance to sustain the mine over the course of pre commissioning, commissioning and ramp up activities during the second half, helping to keep Rochester production on track for 2023 guidance. Getting into a bit more detail with a summary of recent milestones and what remains ahead at Rochester. Following on schedule, first quarter mechanical completion of Pad 6 and the metal core process plant, we are currently finishing wet commissioning and getting ready to start. Work on the Merrill Crusher Corridor is progressing well. Prescreen equipment and piping construction as well advanced. The stacker and feed conveyors have been erected including core sale, secondary and tertiary stockpile stackers as well as the secondary feed conveyor. The 63 KV power transmission lines to the crusher substation have been energized, secondary and tertiary crushers are in the final stages of electrical construction and programming of the crusher process control systems is also complete. On the mining side of the project looking at Slide 9, mining rates are scheduled to increase from 65,000 tonnes per day to 155,000 tonnes per day. Capacity for drilling and loading is already in place and no additional equipment is needed. The whole truck fleet will go from 14 trucks to 29 trucks. And we are currently right on plan to be 22 trucks by the end of 2023 and the full complement by the end of 2024. Headcount for the expansion is less than a 20% increase, and all additional people for the processing plant are already on board. Much like the first quarter, poor whether continue to affect overall project progress during the second quarter. The frequent periods of lightning creating a particular safety challenge. Considering the numerous work streams involving steel erection at heights and crane operations on the crusher corridor. Taken together with ongoing inflationary pressures and skilled labor availability and productivity challenges. We expect the total project capital to come in between $710 million to $730 million, or about 6% to 9% above the previously estimated $607 million discussed in last quarters call. Capital pressures notwithstanding, the pace of project development continues to advance. With mechanical completion of the crusher circuit expected in the current quarter and ramp up to take place over the remainder of this year and into early 2024. In the near term, we expect second half production at Rochester to form more evenly between the third and fourth quarters. Additionally, we anticipate costs in the second half of the year to be similar to the first half of the year as we complete the project and begin ramping up. Turning to Kensington. The slow start to the year persisted in the second quarter with higher than expected water flows in key production areas further impacting a planned return to optimal stock sequencing. We have worked with the team at the site to develop a solid main plan for the second half. And recent performance indicators are looking more favorable. But improved performance is not expected to meet the original 2023 production guidance. As a result, full year guidance has been revised to between 84,000 and 95,000 ounces. Lastly, at Wharf. Results were slightly ahead of plan with the second quarter benefiting from high grade material and tons placed earlier in the year. We're very proud to mark two big milestones at Wharf. Firstly, on July 28, the State of South Dakota approved the permit allowing for mining of the Boston expansion. A nearly 50-acre parcel immediately to the south of Wharfs current permitted operations, giving us more flexibility and providing additional opportunities for mine life growth going forward. Another milestone, the team at Wharf produced its 3 million ounces of gold on June 23. Since Coeur acquired Wharf back in 2015, the mine has generated free cash flow for the company of approximately $360 million and continues to play a key role as a cornerstone of stable gold production in the heart of the United States. Looking to the balance of the year, the ounces deferred Kensington have resulted in overall gold production guidance decreasing slightly to between 304,00 and 352,500 ounces of gold. While silver production guidance remains unchanged at between 10 to 12 million ounces. Coeur remains in a strong position midway through this critical year for the company. With that, I'll pass the call over to Tom.
