Please note that all dollar amounts mentioned on today's call are in US dollars. And let's otherwise note it, and that all unit cash costs and all in sustaining costs are in a corporate equivalent payable fund basis. I would now like to turn the conference over to Ernesto Valerezo, chief executive officer for Sierra Metals. Please go ahead.

Thank you, Lea. Let me begin, as we always do, by discussing our company's number one priority, safety. As seen on slide four, our focus is to continuously ensure we provide a workplace environment where all our employees and contractors are safe. Amongst the many initiatives undertaken during the quarter, the most significant was the risk management leadership program that advanced our technical competencies and leadership skills that are necessary to manage risks and critical controls across our operations effectively. These training workshops reinforce our commitment to decision-making guided by safety and sustainable mining. Moving on to our performance for the quarter, we released our third quarter 2024 production results on October 15 and our financial results earlier today. I assume everyone has had an opportunity to review them, so I will not be going into detail, but will instead provide highlights, as seen on this slide. On a consolidated basis, in the third quarter of 2024, our two operating mines, Yauticocha and Bolívar, processed almost 669,000 pounds of ore, which was 7% higher than the second quarter of 2024. Breaking this down, production by metal was higher than in Q2, with copper production of 11 million pounds being 29% higher, silver production of 503,000 ounces being 30% higher, and gold production of nearly 4,000 ounces was 16% higher, all of which is encouraging given rising metal prices. At the same time, lead production was lower and zinc production flat. As a result of -over-quarter improvements, cash flow from operations was over $22 million, which was 48% higher than in Q2. Jean-Pierre will provide more details on our stronger financial position shortly. I'll also remind everyone that we sold the QC mine and its surrounding concessions in early Q3, allowing the company to receive $2.1 million in net proceeds and save nearly $300,000 per month in care and maintenance expenses. More importantly, this allows us to direct our full efforts and resources to perform in both Yauticocha and Bolivia. Looking ahead to Q4, we expect a strong fourth quarter as Bolivia continues its steady state production level, near capacity, and Yauticocha ramps up production towards full capacity. As a result, I am pleased that both mines met our high expectations for the quarter, and therefore very pleased to say that we expect to exceed our consolidated production guidance for the year. Moving on to slide 6, Bolivia processed nearly 402,000 tons of ore, which represents a 7% and 11% increase from Q2 2024 and Q3 2023, respectively. Copper, silver, and gold production increased by 3%, 17%, and 12% respectively when compared to Q2 2024. Cash costs and all-in sustaining costs per pound for Q3 2024 were 2.42 and 3.23 respectively. Cash costs improved at Bolivia due to the combined impact of lower operating costs per ton and higher grades, which were partially offset by an increase in the sustaining capital expenditure. The sustaining capital included a cost to develop, a total of 3,800 meters, which included 1,700 meters to prepare new operating stoves for production, and 2,100 meters for new ramps and underground accesses. Development in Q3 was focused on the Bolivar Northwest, Bolivar Northwest South, Dulce, and Cieneguita zones. Also shown on this slide, there are some of the major initiatives completed in Q3 and others now underway in Q4. A priority for us is to continually replace and grow our mineral reserves and resources. Exploration works at Bolivar this quarter included drilling over 10,000 meters as part of an infill program in the Bolivar Northwest, Cieneguita, and Dulce areas. The main purpose is to reclassify and further define the resources and extend the ore body to the northeast of Dulce. Slide 8 shows our 2024 guidance range as compared to actual -to-date productions and costs. As indicated on this slide, given the production levels achieved to date and our -to-date costs compared to guidance, we expect a strong fourth quarter of operations. Success at Bolivar is a key driver for the company's overall performance. Moving on to slide 9, Yauticocha averaged a processing rate of over 3,000 tons per day, or a total of nearly 267,000 tons in Q3, our highest in over two years. This was an increase of 5% over the previous quarter as the mine commenced extraction activities below the 11-20 level. Head grades and recoveries for copper, silver, and gold improved in comparison to Q2 but dropped slightly for zinc and lead. The higher grades were due to increased contributions from the Esperanza Zone and the Copper Ridge Zone of Pamela. As a result of higher throughput, grades, and recoveries, copper production was 97% higher with silver and gold higher by 43% and 41% respectively when compared to the previous quarter. Yauticocha's cash cost per pound was 3.25 and all in-sustaining costs were 3.75. The previously discussed operating improvements resulted in slightly lower costs as compared to Q2. As you would expect, the focus for the quarter was on mineral extraction below the 11-20 level. This included constant improvements in equipment utilization and increasing existing shaft usage. Replacing mineral resource and resources is just as important as Yauticocha. In Q3, underground exploration at Yauticocha was focused on replacing mineral resources and nearly 8,800 meters of diamond drilling were completed in the main mineralized bodies. Polymetallic ore and copper were intercepted which will replace the mineral depleted during 2024. As seen on this slide, surface exploration was focused on carrying out detailed geological work and geomechanical sampling to define the polymetallic areas in the El Paso, Fortuna, and Vizcachita Zones. We also have other areas of high priority brownfield targets identified that we will work on shortly. Indicated on slide 11, we expect a strong fourth quarter of operations as we ramp up to full capacity. Furthermore, given the results to date, we expect Yauticocha to beat annual cost guidance. We are very pleased with the progress being made at Yauticocha and expect to announce shortly our achievement of hitting capacity throughput rates. Now over to Jean Pierre to discuss our financial results.

Thank you, Ernesto. I will now provide the key financial highlights of the third quarter of 2024. Overall, our strong operating performance continues to improve our financial position. Net revenues in Q3 were $70.9 million, our highest quarter in more than three years. This was an increase of 23% over revenues in Q2 2024 and was 25% higher than in Q3 2023. Higher revenues were mainly driven by a 19% increase in copper sales and higher metal prices during that period when compared to Q3 2023. Adjusted Q3 evita from continuing operations has been our highest over the last two years, increasing to $20.4 million from $8.1 million in the same quarter of 2023. On a -to-date basis, adjusted evita from continuing operations increased to $51 million from $38 million in the same period of 2023. I also point out that we have generated as much evita in the first nine months of 2024 as we did in all 2023. Dashflow generated from operating activities before movements in that level were $22.1 million for Q3 2024 when compared to $6 million generated in the same quarter a year ago. Net income attributable to shareholders for Q3 2024 was $3.8 million compared to our net loss of $9.3 million in the same period in 2023. At the end of Q3, our net death to last 12 months evita ratio was 1.2 times, which slowed down in the previous quarter. We expect the ratio to improve as we progress our operational and cost efficiency plan throughout the next coming months. Cash and cash equivalents as of September 30, 2024 increased to $18.6 million during the nine-month period. This is a result of cash generated from operating activities of $40.2 million plus the net cash obtained from the refinance loan of $18.2 million that were partially offset by the net cash used for investing activities before $44 million. Capital investments mainly consisted of underground development in both minds, new equipment purchases, concentrator plant improvements, improvements required to meet throughput increases, expenditures at the Yali Kortza shop, the integration tunnel at Bolivar, as well as in pumping and ventilation systems in both sites. In summary, all of our key financial metrics are trending in the right direction. Our financial position has improved significantly on a -over-year basis, and we are well positioned to continue executing our operating plans. Back to you now,

Ernest. Thank you, Jean-Pierre. Shifting now to another very integral part of our business, which is partnering with our local communities on important initiatives that benefit everyone. Our focus continues to be on health, education, and community entrepreneurship. Shown on this slide are some images of the events and initiatives undertaking this quarter in Mexico and Peru. In summary, slide 14 is a reminder of our ambitious 2024 plans and our achievements to date. We continue to check all the boxes as we achieve our goals this year, but we are not done. During Q4, we expect the Yali Kortza to meet full production capacity of 3,600 plants per day. I remind everyone that we received a permit to mine below the 1120 level in late February, so it is remarkable that we have gotten to this stage in just eight months. Meanwhile, at Bolivia, plans continue to rapidly expand the tariff facility, allowing the plant to grow from a throughput rate of 5,000 tons per day to first 7,500 tons per day and then to 10,000 tons within the next few years. And lastly, we continue to seek partners to help us uncover value from our large and prospective greenfield land packages in Mexico and Peru. In closing, I want to congratulate the Sierra Medals team. As we continue to deliver quarter over quarter since January 2023, I truly believe that we have built a foundation to achieve amazing things to continue building shareholder value. With that, I hand the call back to the operator to start the Q&A session. Operator?

Okay, we have a couple of questions coming from the Spanish webcast. I will start with this one. When the auricotra is operating at full capacity, what can we expect costs to be?

Thank you, Dia. We expect cash cost levels to be lower than what they are now. We provide that guidance in our 2025 outlook. I would ask whoever the person is to ask the question to wait for our 2025 guidance. We expect cash but I think they will be good.

The other one is, so far in queue 4, what has the auricotra's production been?

Okay, I don't think I'm allowed to say it. What I will say is that we are very pleased with the operations trending and it is truly going in the right direction. So far, we haven't promised anything that we haven't been able to accomplish. We have said that in queue 4, we will be at full capacity. I continue to say it and to promise that to the shareholders on the market.

We have no further questions. I'll hand the call over to Ernesto for closing comments.

Thank you for taking the time to join us today. Please reach out should you have any questions and have a good day everyone. Thank you very much.

This brings to a close today's conference call. You may disconnect your lines. Thank you for participating and have a pleasant day.
