Thank you for standing by. This is the conference operator. Welcome to the Eldorado Gold fourth quarter and year-end 2022 Financial and Operational Results conference call. As a reminder, all participants are in listen-only mode, and the conference is being recorded. After the presentation, there will be an opportunity to ask questions. To join the question queue, you may press star, then one on your telephone keypad. Should you need assistance during the conference call, you may signal an operator by pressing star, then zero. I would now like to turn the conference over to Lisa Wilkinson, Vice President, Investor Relations. Please go ahead.
Thank you, operator. Good morning, everyone. I'd like to welcome you to our fourth quarter and year-end 2022 results conference call. Before we begin, I would like to remind you that we will be making forward-looking statements and referring to non-IFRS measures during the call. Please refer to the cautionary statements included in the presentation and the disclosure on non-IFRS measures in our management's discussion and analysis, as well as the risk factors set out in our Annual Information Form. Joining me on the call today, we have George Burns, President and Chief Executive Officer, Philip Yee, Executive Vice President and Chief Financial Officer, and Simon Hille, Senior Vice President, Technical Services and Operations. Other members of the senior leadership team will also be available for the Q&A session. Our release yesterday details our fourth quarter and year-end 2022 financial and operating results.
This should be read in conjunction with our fourth quarter and year-end financial statements and management's discussion and analysis, both of which are on our website. They have also been filed on SEDAR and EDGAR. All dollar figures discussed today are US dollars unless otherwise stated. We'll be speaking to the slides that accompany this webcast. You can download a copy from our website. After the prepared remarks, we will open the call for Q&A. At this time, we would invite analysts to queue for questions. I'll now turn the call over to George.
Thanks, Lisa. Good morning, everyone. Here is the outline for today's call. I'll provide a brief overview of Q4 results and highlights before passing it to Phil to go through the financials and Simon to review our operational performance. We'll open the call to questions from analysts. In light of the devastating earthquakes that took place in Türkiye and Syria at the beginning of February and earlier this week, I, on behalf of the Eldorado team, would like to extend our condolences to those impacted by the disaster. In the immediate period following the initial earthquakes, our mine rescue teams from Efemçukuru and Kışladağ mobilized to the impacted area. A number of these team members are highly trained in underground mine rescue, a much-needed skill for earthquake rescue and recovery efforts.
The teams were able to save several lives and recover victims so they could be returned to their families to be grieved for. Tuprag, Eldorado's Türkiye subsidiary, donated blankets, raincoats, and other essential supplies to support those in the earthquake-affected regions. Working with our colleagues in Türkiye, we will continue to provide aid and assistance to support the relief efforts as needed in the days, weeks, and months ahead. Fortunately, our operations are located over 1,000 km away, we're not impacted by the earthquakes. We will continue to assess the situation, our top priority, as always, is to ensure the continuing safety and well-being of our team members. I would like to thank our entire team in Türkiye for responding so quickly and compassionately to this tragedy. These efforts have been an inspiration for all of us.
We faced operational challenges in early 2022. However, through diligence and resilience, we improved operational performance continuously over the year. Fourth quarter production was strong across all assets, which resulted in second half production being 20% higher than first half. Our full year production of almost 454,000 ounces was 1% below the bottom end of our guidance range. In conjunction with our financial release yesterday, we published our 2023 guidance and five-year outlook. We have introduced Skouries into our longer-term outlook, with commercial production expected by the end of 2025. We are forecasting gold production to be between 675,000 and 735,000 ounces by 2027, representing a 55% increase over five years. Simon will speak to the operations and our guidance in more detail later in the call.
Touching on cost. We continue to face inflationary pressures similar to the wider market. Throughout 2022, we experienced price increases for commodities and consumables, including electricity in Türkiye and Greece and fuel and reagents at Kışladağ. Our full year 2022 cash operating costs and total cash costs were above our consolidated guidance, while our all-in sustaining cost was within guidance driven by our disciplined management of sustaining capital. Phil will touch on our cost in more detail later in the call. Shifting to Skouries, in December, we announced the milestone news regarding the Greek bank financing and conditional board approval for the full restart of the project. The project level financing covers EUR 680 million or 80% of the expected funding required to complete the project at competitive interest rates.
The remaining 20% of the project funding will be fully funded by Eldorado. The financing is subject to customary closing conditions, which are expected to be completed in the first quarter. With Skouries financing announced, we have delivered on our multi-year strategy in Greece, including the approval to deploy dry stack tailings, the amended investment agreement, investment in early works construction, and finally, a fully funded financing package that allows us to shift into project execution and achieve commercial production by the end of 2025. On the sustainability front, in the fourth quarter, we completed our first ever integrated SIMS compliance audit at Lamaque. As part of this global process, a delegation of auditors, including colleagues from our operations in Greece and Türkiye, reviewed Lamaque's performance as set out in our internal standards, referred to as the Sustainability Integrated Management System.
PwC provided limited assurance against all the PwC and site compliance against the World Gold Council's Responsible Gold Mining Principles. The completion of the audit is a major milestone for Lamaque and Eldorado as we journey towards full implementation of SIMS and leading ESG performance against our peers. I'll stop there and turn things over to Phil for a review of the financial results.
Thank you, George. Good morning, everyone. Slide 6 provides a summary of our fourth quarter and full year financial results. Eldorado reported net earnings attributable to shareholders of $42 million or $0.23 per share in the fourth quarter, and net loss of $49 million or loss of $0.27 per share for the full year. After adjusting for one-time non-recurring items, including deferred tax expense related to foreign exchange translation and write-down of assets, adjusted net earnings was $26 million or $0.14 per share in the fourth quarter, and $10 million or $0.05 per share for the full year. Free cash flow in the quarter was $11 million, primarily due to higher sales.
Cash operating costs averaged $741 per ounce sold in the fourth quarter, and $780 per ounce sold for the full year, which was 5% above the 2022 guidance range, mainly driven by price increases for commodities and consumables. All-in sustaining costs averaged $1,246 per ounce sold in the fourth quarter, and $1,276 per ounce sold for the full year, which was in line with the guidance range. In 2023, our consolidated cash operating costs guidance is $760-$860 per ounce sold, and all-in sustaining costs guidance is $1,190-$1,290 per ounce sold, which reflects ongoing inflationary pressures related to key consumables such as cyanide, electricity, diesel, explosives, cement, and labor.
In line with commitments under our collective bargaining agreement in Türkiye, labor costs increased in January 2023 to support our workforce with the rising cost of living related to high inflation rates. Labor costs in Türkiye are based in lira, which has remained stable in recent months. As a result, cost increases in local currency are not expected to be offset by currency movements as they have in the past. Capital expenditures on a cash basis were $81 million in the fourth quarter and $290 million for the full year, which included continued investment in growth projects at Kışladağ and early works at Skouries. Income tax recovery is $24 million in the fourth quarter and $61 million for the full year. Current tax was lower in 2022 compared to 2021 due to lower sales volumes, partially offset by lower investment tax credits.
Turning to slide 7. At quarter end, we had unrestricted cash equivalents, and term deposits of $350 million, up slightly from last quarter. We continue to focus on maintaining a solid financial position, which provides flexibility to unlock value across our business. With that, I'll now turn it over to Simon to go through the operational highlights.
Thanks, Phil, and good morning. I'd like to start with a health and safety highlight. Recently, Eldorado's Quebec exploration team received Safe Day Every Day Gold Award. For the greatest number of work hours without a reportable injury among Canadian exploration groups from the Association for Mineral Exploration and Prospectors & Developers Association of Canada. I'm very proud of the team for this recognition as it demonstrates our strong safety culture. Now moving to our operating results. We produced 128,453 ounces of gold in the fourth quarter with a cash operating cost of $741 per ounce sold.
Full year 2022 gold production was 453,916 ounces, which was just below the bottom end of guidance range, driven by lower production at Kisladag and Olympias. Looking ahead to 2023, our consolidated gold production guidance is forecasted to be 475,000-515,000 ounces. Down slightly from our previously published 2023 guidance. Which takes into account modifications to the production plan and higher stope turnover expected at Lamaque, as well as an assumed slower ramp-up at Kışladağ with the commissioning of the fine ore agglomeration drum in the first half of the year. Slide 9 looks at our operations in more detail. Starting at Türkiye, at Kışladağ, fourth quarter production was 40,307 ounces and cash operating costs of $709 per ounce sold.
In the fourth quarter, eight larger high-capacity conveyors were installed, which has improved material handling and on-belt agglomeration. As we mentioned last quarter, in conjunction with the North East Leach pad, we have also purchased an agglomeration drum, which will treat a fine ore split of the HPGR product to improve quality, consistency, and friability on the pad. We are confident that we will have the agglomeration drum commissioned in the first half of 2023, as the equipment is on-site and construction is progressing well. With this investment, stacking is expected to continue on the existing leach pad until mid-2023, at which time stacking is expected to commence on the new North East Leach pad. Looking ahead to 2023, Kışladağ's production guidance is between 160,000-170,000 ounces of gold.
To achieve this, Kışladağ is expected to mine and place on leach approximately 12.5-13 million tons of ore at an average grade of 0.7-0.75 grams per ton. At Efemçukuru, fourth quarter gold production was 21,362 ounces. Cash operating costs of $738 per ounce sold. Gold production throughput, an average gold grade at Efemçukuru were in line with the plan for the fourth quarter and the full year. For the year ahead, Efemçukuru's production guidance is forecasted to be 80,000-90,000 ounces of gold. The site is expected to process approximately 530,000-550,000 ounces of ore at an average gold grade of 5.5-6 grams per ton. Now moving to Lamaque.
Fourth quarter gold production was 51,349 ounces, a 20% increase over last quarter, driven by higher grade and increasing throughput performance at the mill. Cash operating cost was $541 per ounce sold. Resource conversion drilling from the Ormaque exploration drift will continue in 2023, targeting the upper two-thirds of the Ormaque deposit. Results of conversion drilling up to mid-2023 will be incorporated in our mineral resource and mineral reserve update at the end of the year. In 2023, Lamaque's production guidance is 170,000-180,000 ounces of gold, this is based on mining and processing 860,000-870,000 tons of ore at an average gold grade of 6.25-6.75 grams per ton.
Moving to Greece. At Olympias, fourth quarter results was 15,435 ounces, and the cash operating cost was $1,325 per ounce sold. Overall, 2022 production for Olympias was below plan due to lower than expected tons processed and the availability of ore stopes. We continue to implement an operating initiatives designed to improve productivity. Next year, Olympias production guidance is 60,000-75,000 ounces of gold, and the site is expected to mine approximately 460,000-490,000 tons of ore at an average grade of 7.5-8.5 grams per ton. I'll stop there and hand back to George for closing remarks.
Thanks, team. We have an exciting year ahead of us. We are focused on delivering our operational guidance and transitioning to project execution at Skouries. Our priority is to continue to implement our growth strategy, with production expected to reach between 675 and 735,000 ounces of gold by 2027, which will position us well to maximize value for all stakeholders. Thank you for your time. I will now turn it over to the operator for questions from our analysts.
Thank you. We will now begin the question and answer session. To join the question queue, you may press star, then one on your telephone keypad. You will hear a tone acknowledging your request. If you are using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, please press star then two. Once again, to join the question queue, please press star then one now. Our first question comes from Kerry Smith of Haywood Securities. Please go ahead.
Thanks operator. Congratulations on a good quarter, guys. For Skouries, my first question is you have $240 million-$260 million of CapEx this year. Could you just maybe kind of give me a rough idea as to what the CapEx might be like for 2024 and 2025 to finish out that project? Just the spend.
Thanks for the question, Kerr y, and congrats. Next year, we expect the capital cost to ramp up above that $250 million middle point of guidance, and then drop down in the final year. We'll obviously have some revenue coming in in the second half of 2025 as we do the commissioning.
If I was to assume $300 million for next year, and then I guess we assume $750 million in total, just have the difference in 2025. Would that be reasonable then, George?
That's reasonable, Kerry.
Okay. Okay, great. Just on the EUR 680 million debt package that you've pretty much got finalized, and you hope to have it all signed up and done here by the end of the quarter. How will the drawdown schedule work? Can Phil maybe just remind me how that schedule will work? Like, how you have to spend equity as you spend the debt, or whether you can spend so much debt before you have to fund any more equity, just how it will work.
Maybe I'll answer high level and Phil can jump in. The way it works, Kerry, is it's an 80-20 split between ourselves and the project financing. We've pre-funded the part of the capital required to reach commercial production from the investments we did last year that were part of the feasibility study. We're a bit ahead of the game. The banks have to play catch up at a 4-to-1 ratio on the funds we completed last year. There's EUR 120 million of bank-based pre-funding, EUR 30 million, basically. We don't expect to spend anything off our balance sheet once we do first drawdown in the first quarter till Q3 of this year.
Okay. Okay. In Q3 is when you think you'll start participating in terms of funding then?
Yeah. I mean, we're still funding. We are ramping up the construction activities. In fact, this week, we poured concrete for the first time on this restart. We're continuing to fund in Q1. Once first drawdown happens, we expect the funding to come from the banking syndicate until the third quarter of the year. We'll be at a 80-20 funding rate after that.
Right. Gotcha. Okay. Okay, great. That's helpful. Just on Kışladağ with the drum agglomerator, what sort of recovery are you expecting once that agglomerator is up and operational?
Kerry, what's included in our guidance right now is still the 56% recovery that was justified as part of the capital investment for HPGR. You know, this year, the first quarter was pretty challenging for us. We had an abnormally cold winter, but we also found the need to add cement as a binder to get good permeability through that finer ore that came out of the HPGR. Those challenges is really why we didn't hit our guidance last year. As you saw, each quarter, we ramped up the tonnage and began to deal with the reality of agglomerating cement on the conveyor belt. We're back, I'd say, at the run rate we had on a tonnage basis prior to cement agglomeration. What the fine ore drum does for us, it makes it a better agglomerate product.
We're gonna be agglomerating the fines in the crushing circuit. That'll be combined with the coarser material. So the cement won't be added on conveyor belts. It'll be added in the crushing facility. We think that's gonna give us some additional relief on the conveyance system itself. Now, in terms of what ultimately recovery ends up, we're pretty optimistic we're gonna beat the 56%, but we haven't publicly put a number on it. Bottom line is we know we get better permeability through the pad. That has a pretty positive effect on leach cycle time. Ultimately, we think we can further optimize how fine the HPGR crushes the ore with a better agglomerate. That could lead to better recovery.
We're not putting a pin on what we think that upside is, but we're, you know, we're believing this year we'll be able to really sort that out. With the finer agglomeration commissioning being completed midyear, we'll have about six months to understand the benefits we're getting out of that optimization between crushing finer, maintaining good permeability through agglomeration. Pretty optimistic, we can beat the 56%, but we haven't included that upside in guidance, and it's really too early to pin a number on it.
What is the size of the fraction coming out of the third stage of crushing? Now like how fine is fine? What % is that?
Yeah, Simon. Go ahead, Kerry. Sorry.
I was just going to say, what % of the total tons to the pad actually is going to go through the drum agglomerator from the fine circuit to be agglomerated?
Yeah. Hi, Kerry, it's Simon. We're probably planning around 30% of the tonnage to go through the final agglomeration. It potentially has higher capacity than that. The plan at this moment is to take that 30% feed rate. To the size of the particles, the answer is probably, you know, less than 1 mil on average. That's what we're sort of classifying as fine.
Okay.
Yeah. Just a little color around it. We're really trying to get the fines to stick together in kind of balls to create that permeability and allow oxygen to get into the pad. You want a little bit, of course, to get in there with it to give the core of those agglomerate balls to have, you know, something to build upon. Basically, we're trying to get the finer material with a bit, of course, into that drum to make a good agglomerate and to take pressure off the transfer points between the grasshopper conveyors, which is where we're doing the mixing currently.
Right. Okay. Okay. Yeah. Almost seems like maybe the mill would've been the way to go. You're getting pretty fine there now.
Yeah, Kerry, hindsight's always 20/20.
Yeah.
If you recall, the mill scenario was a half a billion.
Yeah.
Capital up front. I, you know, at a high metal price, the mill's a better answer. Based on, you know, the decisions we had at the time, we made the right decision with heap leaching.
Right. Just last question, if I could. Just, when would Ormaque be incorporated into the mine plan? When will we have a reserve there? When will the drilling be to the level where we can get a reserve? Is that the end of this year then, George?
We're doing the infill drilling as we speak. We're making good progress on that. Do we need an adequate amount of conversion to be able to call it a reserve? I'd say we're on track with getting that done, end of the year, early next year. You know, we'll do a technical report when that's all completed. In terms of the timing for bringing on Ormaque, I mean, that we need to do trade-off studies to say, what's the best solution here? You can make arguments right now on both sides. If you bring Ormaque in early, you really have two mining fronts, and as we get deeper in Triangle, that would be a positive. Of course, if we do that, we need to put some capital in upfront to put in ventilation and, you know, set up for stopes.
We'll be doing a trade-off study as we complete the ore reserves to determine what the optimum life of mine scenario is for Triangle and Ormaque.
Right. Okay. That trade-off study won't happen until you've got the infill drilling done. That would be a 2024 event then, I guess, to do the trade-off studies.
Correct. That's correct.
Okay. Gotcha. Okay. That's helpful. Thank you very much, guys. Congratulations. That was a good quarter.
Thanks, Kerry.
Once again, if you have a question, please press star then one. Our next question comes from Tanya Jakusconek of Scotiabank. Please go ahead.
Great. Good morning, everyone. Thank you so much for taking my questions. Thank you very much for the capital that you answered for Kerry with respect to Skouries and how that's gonna pan out over the next few years. What I also wanted to ask is, how should we be thinking about the sustaining capital going through as we go to that 700,000 ounces per annum rate by 2027? If I do a quick calc right now, it looks like you're paying about $250 an ounce on sustaining capital. Seems a bit low relative to some of the other companies that are coming in at $350-$400. Just wondering how I should see that going forward.
Well, I mean, when you look at the existing portfolio, on sustaining capital, I think the run rate on sustaining is gonna continue. If you're talking about over the five-year guidance, it's really bringing in Skouries. For Skouries, the copper byproduct revenue is gonna pay all the sustaining and operating costs. You know, we end up with a slightly negative AISC. In terms of the sustaining capital number, I don't have that number right on the tip of my fingertips. I think I can probably answer that before this call is over. Get somebody to pull the number.
Okay. That would be very helpful. Thank you. Just also, my other question has to do with just how do you see the year play out? Obviously, you've given some guidance that second half is going to be stronger with the, you know, with the Kışladağ, having a stronger performance. What about Lamaque? 'Cause Lamaque last year was, you know, had higher grade in the first part of the year and then lower grade. Just wonder how Lamaque plays out this year.
Yeah. For Lamaque, it's again, this year gonna have a bit of a stronger second half than first half driven by grade. Probably, well, not as significant as it was last year for sure. The first part of the question?
No, it was how that's panning out. If I think about, you know, your production profile during the year, would it be like a 45% first half, 55% second? Would that be a reasonable assumption given Lamaque and Kışladağ both second half?
Yeah, that's a good assumption. Just to follow up on Kisladag, really, what's driving Kisladag, we're doing a tie-in to that HPGR. We're doing a rebuild on the HPGR for the first time. We've tied that shutdown to get all that work done at one time. We're gonna be down for a number of days during that tie-in. You know, we're expecting some better performance in the second half at Kisladag just from a grade recovery perspective.
Okay. That's helpful. Thank you. My other question has to do really with Olympias and just the expansion permit. Just wanna try and understand what's going on there. In your five-year guidance, what have you assumed for that? Because, you know, we've continued to wait for this permit. I think it was 2022, now it's 2023, in terms of how do we deal with the, with the ore. I just kinda wondered what you have in your forecast and where are we on, on your thinking there and the permit.
Good question. A couple components to that question. First, I would say permitting itself. This is a modification to the EIA that we're seeking, and that process requires public consultation. After the public consultation in Greece, there are a lot of departments within government that then review the consultation and look at all the environmental issues that need to be addressed. We're pretty well through. We're done with the consultation. We're pretty well through the comment period from the various departments, and we're in the stages now of finalizing the document itself that will be the control document for our Kassandra operations. You know, the significant change here is the ability to increase capacity in the mill and to be able to move more tons out of the underground.
Obviously, noise, vibration, water quality, air quality are all things that are modeled and monitored. I would tell you that process has taken longer than we would have liked, but confident we'll get that permit this year. It's not on the critical path for the ramp up of Olympias. On your question, the five-year guidance that we have this year and we had last year, assumes we get the AIA, assumes we make some minor capital investments to allow higher throughput through the plant. There's a bit of capital on the Stratoni port included and a bit of capital on the underground to support the ramp up. The critical path on making all this happen is really getting the tons out of the underground. Last year, you know, we made good progress.
In the fourth quarter, we had our highest tons out of the underground. When you look at our performance at Olympias from a cost perspective, it wasn't a good quarter. The challenge we have, Tanya, is that we're in a process. We gotta reduce the cost and drive the denominator up at the same time. On the cost front, one of the major drivers is the number of people we have. You know, we shut down the Stratoni Mavres Petres operations last year. It was our non-core base metal mine. Lack of reserves, old equipment, we came to the conclusion that it wasn't gonna be profitable in this current environment, and we shut it down. We did not lay off the workforce.
We've had reductions last year, but we're carrying a larger workforce than we need to run Olympias. Our costs haven't come down even though we are making progress on productivity and efficiencies. This year is the year it's gonna change. It's because as we ramp up the Skouries operation, we're gonna be creating significant jobs during the construction phase. As we move into production, we'll be adding jobs from an operating perspective. We've made the decision to cushion the blow on the workforce and allow these new jobs to be created, allow people to move out of the redundant jobs into construction jobs and ultimately into new operating jobs. We're carrying a higher burden on labor. We are improving the productivities and efficiencies.
This year, as you see from the guidance, we're expecting higher production, and we're expecting those costs to come down materially from what they were last year. Once we ramp up production, post the permit and post delivering on productivities and efficiencies to support this nominal capital investment, then you'll see another kick up in both production as indicated in the five-year plan, but more importantly, driving those unit costs down and creating margins and profitability.
Okay. If I remember correctly, and remind me if I'm wrong, but I thought like the expansion itself was gonna cost in sort of like the $60 million range or thereabout just for the. Is that still a number that I should be using?
Yeah. $650 is still the number. From a current perspective,
Okay.
400-
I was talking about the CapEx.
Oh, sorry. I thought you were talking production. Could you repeat the question?
Yeah. It was just on the expansion, when you said there's some monies that have to get to do all of that besides the underground, which I'll leave, but everything else on the infrastructure. I think getting to that 650 tons, like that was gonna cost about $60 million, six zero. Is that still?
Yeah, that number's come down a bit. We're in the range of $35 million-$40 million. The reason for the drop, we've had success in debottlenecking the plant this year without substantial capital. In looking at that success, we've taken down that expansion number to between $35 million and $40 million.
Okay. Just in your five-year plan, just to finish off, when you've assumed you get your EIA this year, and then when are you going to the expanded rate?
Yeah. In 2025, we're assuming we're at the expanded rate.
Okay. Given we're having all of, some movement of people from Stratoni and from Olympias going to Skouries, what would be the holding costs we should think about through the income statement for Stratoni this year?
Phil's grabbing that number.
I'll leave.
Hi, Tanya.
If I could get the holding cost and the sustaining capital, that would be awesome.
Yeah. Like I think as George outlined, Tanya, we do expect to see the holding costs kind of steady until Skouries restarts construction. In the long term, we're anticipating, you know, care and maintenance costs for Mavres Petres Stratoni to be in the range of, you know, two and a half to three and a half million dollars a year.
Okay. Phil, anything on the sustaining you can help me with longer term, or should I use that $250 allowance?
I need-
$150 million per year.
On the sustaining CapEx?
Yes.
The sustaining CapEx, I think for, you know, the current operations is probably pretty consistent with what we've seen in 2022. Then you add on Skouries, and the sustaining CapEx for Skouries would be in line with the feasibility study. Over time, as we go through the five-year plan, you're gonna see sustaining CapEx at Kışladağ and Lamaque to start to decrease.
Yeah. No, fair enough. Okay. No, appreciate all of the insights, and I'll pass it over to someone else to ask questions. Thank you.
Thanks, Tanya.
Our next question comes from Mike Parkin of National Bank. Please go ahead.
Hi, guys. Just a follow-up question on Olympias. You report your tons milled for the operation. Are you building a stockpile? 'Cause I'm just noticing, like tons milled in 2022 versus 2021 was fairly flat, but your comments are you're getting better performance out of the mine.
No, we don't have much of a stockpile. Really what you looked at is a tough Q1 at Olympias due to, well, across our portfolio, we were hit by COVID for the first time. We had high absenteeism, and every one of our sites were impacted. Olympias got hit with that in Q1, and the better performance was really in the second half at Olympias, ramping up that tonnage. Yeah, overall, year-over-year, you didn't see much improvement. If you look at the second half in fourth quarter production out of Olympias relative to prior quarters, a significant uptick.
Okay. It's fair to assume what's milled is what's mined.
Yeah. There's just very little capacity to stockpile material at Olympias, underground or on the surfacers.
Okay. Any kind of tick up in production year-over-year is largely grade-based until we'll get this expansion online in 2025, or you're expecting some tonnage improvement year-over-year as well?
Yeah. We're expecting tonnage improvement this year over last year. You know, fourth quarter, again, we had good tons, but we didn't in the first half. You know, we're expecting to get better tonnage out of Olympias and more consistency this year than last.
Again, in 2024, you'd expect tonnage to be up again?
Well, it's really permit dependent, so we're gonna be pushing that production out of the underground as hard and fast as we can. When we hit the bottleneck of the plant, it'll be that expansion capital required to debottleneck it. I don't know, maybe it's helpful to just add a few comments on catalyst for Olympias this year. There are a number of projects underway that will be completed this year. They're gonna support better economics. One, we've been running with the transformer that is at its full capacity. We've completed construction on an upgraded transformer that is suitable for the expansion that's underway, but will lower our unit cost for electricity just 'cause we're right at the top end of that old equipment's capacity.
We're waiting for a turnover and tie-in from the national grid and expect that to happen in the first half. A number of other projects that we've talked about in the past, we're going to emulsion blasting that enables us to have longer blasts, better productivity in the mining cycle. We've got the permits for it. A piece of gear being manufactured in Europe is expected to be deployed in Q2, and that's gonna drive productivity and efficiencies in drilling and blasting and the whole mining cycle. There are a number of catalysts just beyond the labor that I mentioned earlier that are gonna drive better performance out of Olympias. Just note that, you know, this has gone slower than we would've liked.
You know, and I know this is an opportunity for us to gain a bunch of credibility to get Olympias into a profitable criteria. Maybe one last comment, and it is a pretty significant bottleneck right now, is ventilation. We are in the middle of constructing some new ventilation fans on surface that'll make a material change in airflow, allow us to be mining more faces underground, open up in parallel areas to be mining. There are a number of projects underway that are going to help our team in country to improve their performance and then, you know, getting the full-time equivalent workforce consistent with Olympias being profitable. Expect that to happen as well in the first half of this year.
That's great. That's really good color. Thanks very much.
Thank you.
