Thanks Scott. Good morning everyone. Before I get started, I'd like to recognize the efforts of the many employees, the contractors, consultants who worked tirelessly over the past year to bring forward this new technical report and extend the life of mine for Kumtor. I’d especially like to thank the Kumtor employees for the results that they put forward in 2020 under such challenging circumstances during COVID and after our tragic accident that we had in 2019 and early 2020. Since then, as Scott has indicated, we've had an excellent safety record at Kumtor where today we are at 331 consecutive days, with little lost time incidence. I’ll take you to the next slide of the agenda. This is the agenda we’ll be going through. I will take you through the technical highlights which Malcolm Stallman after us, he is our VP of Exploration, he’ll discuss the Kumtor exploration potential. As an introduction, we've been operating the Kumtor Mine now for some 24 years and have been operating since 2009 under the concession agreement which was a comprehensive rights agreement that runs until 2042. During this time we have not had a meaningful operational interruption and we anticipate to be able to continue under the terms of this agreement going forward. If you go to slide 13, this is the layout of the concession. The grey area in the center is the footprint of the ultimate pits and you can see that our Central Pit and Sarytor Southwest are now coming together along straight lines, which extends both to the southwest and the northeast. If you go to slide 14, Kumtor is certainly a world class assets. There have been many years with production in excess of 500,000 ounces and we anticipate this level going forward with this new life of mine plan. At the end of 2020, Kumtor has not produced more than 13 million ounces of gold at a sustained, an average grade of 3 grams per tonne. The future see us extending the pit in both directions and the depths with the new Cut-back hockey stick to the southwest and Cut-back 21 and 22 to the northeast. Next slide, in terms of performance, as a very large open pit was substantial ore stockpiles that we blend for the mill feed, Kumtor operates at a fairly steady gold production rate between 500,000 and 600,000 ounces per year, at an all-in sustaining cost of between $600 and $1,000 per ounce. The reserve is now increased to 6 million ounces at an average grade of 2.66. The previous announced increase in resources have been reduced because of this conversion. Just in the past year in 2020, Kumtor had an operating cash flow of $661 million and a free cash flow of $438 million U.S., which shows the quality of the asset. With the exploration drilling program that commenced two years ago, that had been previously stopped for five years, we successfully increased the proven and probable reserves by 87%. We have continued our near mine exploration program in 2021 with the goal to identify further extensions of the current pits, as well as nearby mineralization. Currently we are not anticipating a start to the underground as current plans require access from the bottom of the central pit, which is currently an active mining phase. This opportunity continues to be analyzed and better understood. If I take you to slide 16, as a result of additional reserves the mine life is now extended from 2026 to 2031. As part of the life of mine extension we have planned to add a small percentage of new equipment which I'll detail out in a future slide. The new life of mine reflects a $1.96 billion net cash flow at $1,350. This increases to just over 3 billion at $1,600 gold. There is limited additional capital requirement, but we have plans for focused capital improvements in the plants to increase recovery and throughput. These include additional leach tanks and a new tower mill. The new life of mine calls for increasing the Tailings Dam each year in the same way that we have over the past few years, by adding additional capacity as required within the current footprint. Finally, our near mine exploration drilling has outlined significant oxide potential and future near term drilling will be focused on this as well as extending the sulphide reserve and resources. Taking you to the next slide 17, here highlighted in red you can see the reserves have increased to just over 6 million ounces. The year-over-year change in reserve and resources reflects a strong conversion of resources to reserves. The 87% increase in reserves gives Kumtor an additional five full years of production. Note, the grade and the reserves also increased from 2.31 to 2.66, giving robust economics of $1,350 in the technical report. The Kumtor underground resource stays fairly much constant at 3.1 million ounces and we continue to do engineering work to tighten up different approaches that it would take once the Centerra open pit is completed. On the next slide, slide 18 at $1,350 gold for 2021 is reflecting a breakeven in terms of net cash flow. This is a transformation year to allow large stripping of Cut-back 20 and accessing substantial ore starting in the second half of 2021. We are currently feeding from lower grade stockpile for the first half of this year. In 2022 to 2026, the release of ore is sufficient to feed the mill at a steady grade of in excess of 3.1 grams per tonne. Thus we are forecasting to produce up to 600,000 ounces per year for these five years. For the year 2027 to 2031, the current plan is to feed full tonnage but a lower grade blend, therefore averaging 330,000 ounces per year. As a result of the current near mine exploration, and as we learn more the potential to bring forward higher grade blend to these future years, to full potential is planned. The reason for final year of the life of mine being higher than previous years, if we plan to mine out the step out we did for Cut-back ’19, that was taken to increase the stability of the pit wall below the plant. This step out is a higher grade ore area, but will only be accessed near the end of the open pit life. Again, at $1,350 goal, the overall net cash flow from 2020 to the end of the mine life is 1.96 billion, fairly spread over the years. Taking you to the next slide, cover sheet on stewardship for the Kumtor mine. Currently – Centerra currently takes its stewardship of the Kumtor mine very seriously and is making all efforts to fulfill its ECG obligations for the benefit of all stakeholders. On slide 20, as a very large industrial operation at Kyrgyzstan, Kumtor is a substantial tax contributor to the state. Since inception, Kumtor has invested more than $2 billion U.S. paid in excess of $1.4 billion in taxes and is near 10% of the GDP of the country. We also contribute to other social programs, both locally and nationally. The extended life of mine is projected to contribute a further $1 billion in taxes and royalties. To go to the next slide, Kumtor has a very skilled national workforce, with only 1% of workers coming from outside the country. Our competitive wages gives us stability and helps us reduce our turnover that's giving us the ability to retain our top talent. Kumtor’s payroll is near $100 million per year and a very large percentage of our near 4,000 employees and contractors live in the region of the mine. A number of our Kyrgyz employees have been promoted to positions in Canada where we utilize their technical expertise that is world class. As leaders in their respective communities, our employees participate in many ways to help improve the lives of their fellow citizens. In terms of supporting strategic community development, as part of our commitment to the stakeholders, Kumtor works closely with local communities with a focus on sustainable activities, female employment, youth employment and training, as well as all other local community development and investment. The microcredit agency that Kumtor initiated have helped small businesses start and develop and is credited for helping to create near 5,000 new jobs in the region. The extended mine life will contribute a further 17 million in direct support to these many activities. Taking you to slide 23 now, as part of our commitment to our host country, Kumtor has embraced the goal of local procurement. Over 25% of Kumtor supplies are procured locally from near 400 different suppliers. Since the beginning of the mine life, Kumtor has purchased in excess of $1 billion U.S. locally. A particular note: For the past five years, 100% of the food required for our 1,800 person camp is locally sourced. The additional mine life will mean an additional local procurement of near 7 million for the country. Side 24, terms of environmental stewardship. As an important part of Centerra’s social license, Kumtor applies the highest standards towards the approach of managing the environmental effects. We hold ourselves to the highest international standards and focus on transparency. Not only do we do constant monitoring on site, we also contribute to the local area in terms of water management for farming, supply of clean water to local communities and participate in waste management strategies in the region. We have a substantial budget and highly skilled environmental employees and consultants to help us achieve our goals and plan to spend in excess of $50 million over the life of the mine. Now I’ll take you to slide 26, get back to the reserves and resources. As indicated, the reserves over the year have increased 87% from 3.2 million to 6 million ounces, reflecting the extension of the Central pit on both sides. One side 27, this is a reflection of the changes of the dates of the techno report from July 1, 2020 to our announced reserve at year-end. This reflects the depletion of the ore from stockpiles during the latter half of 2020, as we were stripping waste from Cut-back ‘20 during this time. Slide 28, in terms of the plan view. There is only a small expansion of the footprint of the Resource Pit Shell. The Resource Pit Shell in the blue from 2019 is expanded only marginally to the left in the Hockey Stick zone and on the right as part of Cut-back ‘21 and ‘22. The total ounces in a resource shell only changed slightly, but the major change is moving ounces from resource to reserve. On slide 29, you can see that this is a sectional view over in Cut-back ‘21. You can see that we have lowered the pit angle on the right side to account for better understanding of the geo text stability as a result of both, actual mining and additional drilling. This section to the left shows that we are not changing the slope substantially due to good stability in this area. To note the upper green line is the bottom of the pit at July 1, 2020. I move you forward now to slide 31. These are pictures of the open pit design. The ultimate pit, mine pit plan are depicted here. The pictures on the top right labels the mining zones. It is important to note that we are not developing any new pit. On the right you can see the areas that we call Cut-back ‘22, both Cut-back ‘21 and Cut-back ‘20 are below this Cut-back. On the left you see the Hockey Stick and Southwest Sarytor near to the west of the Hockey Stick zone. We are mining Cut-back ‘20 currently up until mid-2022. Then we shift to approximately 25% of our efforts over to southwest and 25% to Hockey Stick beginning in 2021. Southwest is completed by 2023, but Hockey Stick continues all until 2025. Cut-back ‘22 starts after Hockey Stick in 2026 and it is our final mining Cut-back ending in 2028. Sarytor starts during that period of time in 2026 and is completed in 2027, as we need to release the ore while we are doing a large stripping of 2022. Next slide, slide 32. We’ve had question before about the fleet. Kumtor has a very large fleet of CAT haul trucks, combined with Liebherr and Hitachi Shovel. The truck fleet is in excellent condition, but due to the longer hauling distances that life of the mine calls for, an additional 29 trucks. In anticipation of this requirement, Kumtor did procure 11 used 789 from Chile in 2020 last year, as well as ordering 10 news 789D trucks from CAT. The first 11 trucks are on site operating, and two of our new trucks have already arrived. The remaining eight of these trucks are in transit; three are in country and five more will be arriving and operating April. Due to productivity improvements in all, including more fully utilizing the mine sense technology, improving loading and efficiency, truck speeds, we have postponed the finally eight trucks and will only procure them if required. This is why our 2021 capital expenditures are forecasted to be less than what we reported in this technical report due to the eight trucks being purchased deferred and potentially canceled. As for shovels, the Liebherr shovels are our smallest and oldest shovels. So we are looking to trade in the four for four larger shovels, and that’s what's depicted in the plant. The plan has not been finalized and will be continued to be studied. The smaller graders of the fleet are being replaced by larger graders as they are retired given the capability to maintain the longer haul distances. The remaining replacement equipment is simply to shut down the older equipment as conditions warrant and replace them with new equipment. I’ll take you to the next slide, the mining schedule. In the mining schedule you can see the phasing of ore release in Central-pit and separately Sarytor in the southwest. The Central-pit cut-backs of cut-back ‘20, Cut-back ‘21 and Cut-back ‘22 are large. Each take two or even three years and the majority of ore in these respective cutbacks or in their last year. To the balance the ore release, the plan is to have ore released from Hockey Stick, Sarytor in southwest during these large stripping segments. The plan is to keep the feed grade at over thee grams per tonne to have enough ore in stockpile to always have targeted feed tonnage for the plants. Slide 34, in 2020 we had focused on Cut-back ‘20 in the northeast with the majority of the waste going to Central Valley dump as we regained permission to utilize the Lysii waste dump. On the next slide 35, currently all of our equipment used in Cut-back ‘20 and 50% of the waste is going to Lysii and 50% is going to Central Valley. We will ship a small amount of equipment to the southwest later in the year. Slide 36, in 2020 we are much more spread out in our mining zones in the Central pit as well as a large Cut-back in the southwest. Slide 37, in 2023 a majority of the focus is the hockey stick and we begin to do cut-back ‘21 again back on top. This is a projection of our stockpile balances, both in past years and the future years. Kumtor has a number of large areas for stockpiling ore with different grades. 100% of the blend of our mill is managed by our metallurgist team to ensure maximum recovery. A large amount of ore is released by Cut-back ’20, starting in the latter half of 2021, but a very high amount in 2022, thus reflecting the large stockpile at the end of 2022, which is subsequently depleted during 2023. You can see the same movements that we had in previous cutbacks during 2018, ‘19 and 2020. This is the addition and subsequent depletion from cut-back ‘18 on the plant side and from cut-back ’19, which was the cut-back below cut-back ‘20. The next slide, slide 39, Kumtor has three main dumps. From left to right they are Sarytor, Central and on the right Lysii. These dumps have all been permitted for their footprints and no new dumps are planned at this time. Over the remaining life of mine, Central will receive 40% of the waste, while Sarytor and Lysii receive 30% each. The loading of each waste dump is tightly managed to limit any risk of movement. Now we shift to the mill. The process flow of the plant, slide 41 has only one change, that being the addition of a Tower Mill, which is planned to be commissioned in October of this year. The additional leach tanks have been delayed from the targeted operation in late of 2020 due to construction issues mostly caused by limited manpower due to COVID. They are anticipated now to be operational in the second quarter of this year. In terms of mill statistics, slide 42, the Kumtor mill has an excellent mechanical availability of 97%, which has been demonstrated over the past few years. We have a strategy at 2x per year of full maintenance shut down and it has proven very successful to keep the mechanical availability high. The plan is to run the plant at $6.5 million tons per year and with the additional leach time due to the new tanks and finer grinding with the Tower Mill, the recoveries are expected to be in the mid-80’s with most of the different feeds. Recovery due to – it will vary due to grade in ore type, but that is taken into account in our planning and focused on when we decide ore blends by our metallurgists. Slide 43 shows the Tower Mill and leach tanks. The capital addition of the Tower Mill and leach tanks are well in programs and both will be contributing to improving our recoveries and increasing our ounces starting this year, and will continue for the life of mine. On the next slide 44, the current tailings storage facility is very robust. With the additional five years of life, the current footprint is only slightly increased and the lifts each year will give us sufficient capacity for non-stop operations. The following slide shows some details on the raising of the dam. The dam is engineered to world class standards by third party experts and external experts to do an annual audit, an inspection of the condition and help us manage the dam. To improve stability, the strategy of excavating a shear key at the foot of the dam to the depth of 20 meters into the base has proven to be very effective. As can be seen on the table, the capital cost of the tailings raising is spread over the remaining life of mine. Construction is contracted out to local earth work contractors and is completed during the warmer summer months of April through October of each year. Finally, we'll bring it to the financials in slide 47. As indicated in the summary highlights, the new life of mine reflects $1.96 billion in free cash flow, a $1,350 goal. Starting in 2022 we have five solid years of production, each producing near $200 million free cash flow at $1,350. The all-in sustaining cost during the same time is in the $650 to $900 range and the life of mine comes in at a very competitive $828 an ounce. Mining cost per tonne were higher in 2020 due to the reduced tonnage, but at full mining rates the mine can run at an average of $1.39 life of mine. Drilling costs are steady near average at $11.34 a tonne. Mill and administration costs come in at $9 and $7.87 life of mine. Next slide, net cash flow at $1,350, it is only during the large stripping years of 2021 this year and 2027 where we are feeding lower grade stockpile or resulting in a break even cash flow. The NPV comes in at a robust $1.55 billion at a 5% discount rate and $1.37 billion at an 8% discount rate. Next slide, in terms of operating costs quickly, Centerra has a long history and experience operating the Kumtor mine, therefore the costs of operating are well understood and is very world competitive. Even with including sustaining capital, the mining cost comes in at $1.66 per tonne mined. The milling cost is just over $12 per ton milled and administration just over $8 per tonne milled. On the next slide, slide 50, as Kumtor is well established and the additional life, life as extension of the current pits, there is little growth capital required to extend the life of mine. Our all-in sustaining costs per year in the full mining years ranges between $400 and $510 million per year. Once mining is completed in 2028, then the remaining three years, the all-in sustaining cost drops to $250 million to $300 million per year. The whole life of mine average all-in sustaining cost grounds comes in at the $853 per ounce, and inclusive of gross revenue tax and capital growth, we are still very competitive at just over $1,000 at $1,044 per ounce. In terms of capital expenditures on slide 51, a majority of new equipment needed to execute the plan is scheduled to be purchased in the first three years. After that the majority capital is mobile component replacement than the annual raising of our Tailings Dam followed by our annual mill maintenance type repairs. If you look at sensitivities, at a 5% discount rate the NPV does come in at $1.6 billion. The value fluctuates most with the price of gold. When gold is increased 20%, the $1,620 an ounce, the NPV increases to $2.5 billion. At a 20% decrease in gold price down to $1,080, the NPV is still $600 million. The NPV is second most sensitive to our operating costs and with an additional 20% of operating costs, the NPV drops to $950 million. Both FX and capital fluctuations have little effect on the overall life of mine NPV of Kumtor. Finally, Kumtor’s opportunities of the future, we call it the golden sunrise. There are a number of large opportunities that we are investigating with Kumtor. The current extension of the Kumtor’s life of mine has all been well assessed. There are also a number of additional opportunities that we can add substantial value to the company. First, the gold in the Kumtor ore is very fine, with the recovery over life of mine of 83%, giving an opportunity to continue to find ways to improve that. As the Kumtor pit deepens, it is now constrained to the northwest by our plant. Additional drilling is shown. The ore body does extend in this direction, therefore at some point it may be economic to develop a new plant. This is also tied to the opportunity number three as exploration is uncovering a potential oxide resource. This would also require a new processing plant, which could be tied to movement of the old plan. Currently the operation utilizes a truck shovel configuration. As mining methods change, there may be an opportunity to move to a conveyor or the like type system, which would also change the location of the waste dumps and potentially use green hydropower. The company has been doing work on testing different methods of recovering gold through the tailings processing. Currently there are in excess of 3 million ounces in our tailings. Finally, the underground resource is well delineated and open in a number of directions, and we continue to study that. Now, Malcolm will take us through the Kumtor’s exploration opportunities.
