Good morning, and welcome, everyone, to the First Quantum Minerals third quarter 2026 results conference call. As a reminder, today's conference call is being recorded. All lines have been placed on mute to prevent any background noise. After the speaker's remarks, there will be a question and answer session. If you would like to ask a question during this time, simply press star followed by the number one on your telephone keypad. If you would like to withdraw your question, simply press star one again. I would now like to turn the call over to Bonita To, Director, Investor Relations and Capital Markets. Please go ahead.

Bonita To
Director of Investor Relations and Capital Markets, First Quantum Minerals

Hi. Thank you, operator. Thank you everyone for joining us today to discuss our third quarter results. During the call, we will be making forward-looking statements. As such, I encourage you to read the cautionary notes that accompany this presentation, our MD&A, and the related news release. As a reminder, the presentation is available on our website and that all dollar references are in USD unless otherwise noted. On today's call are Tristan Pascall, our Chief Executive Officer, Ryan MacWilliam, our Chief Financial Officer, and Rudi Badenhorst, our Chief Operating Officer. With that, I'll turn the call over to Tristan.

Tristan Pascall
CEO, First Quantum Minerals

Thank you, Bonita. Good morning, everyone, and thank you for joining us today for our third quarter results. It's been an eventful three months since our last call, so I'm pleased to have this opportunity to provide you an update. In the third quarter, with the hedge book behind us, we benefited fully from stronger copper prices. This translated into a meaningful improvement in our financial performance and demonstrated the underlying earnings potential of our business, which Ryan will speak to in more detail later in today's call. We also delivered high production in the quarter, which Rudi will take us through in more detail later. I would like to start with the October 9 earthquake in Panama. First and foremost, all First Quantum personnel in the country were reported safe.

Our thoughts remain with the families and communities affected, particularly in the Penonomé area, where some of the most significant impacts were reported. The earthquake was well within the design parameters of the mine, with no material impacts to site infrastructure or environmental protection systems, and the tailings and water management facilities also remain stable and secure. I want to recognize the Cobre Panamá team for their strong and immediate response to the incident and their dedication in assisting local communities with the provision and delivery of essential supplies as part of the wider relief efforts in the country. During the third quarter, we made good progress with the stockpile processing program as part of the ongoing environmental stewardship of the mine. We have successfully recommissioned all three processing trains, marking another important step in the program, and our focus has now shifted towards improving reliability and stability.

In other developments in Panama, on September 30, the Interministerial Commission provided its recommendation regarding the future of Cobre Panamá. The report acknowledges that maintaining the site indefinitely without a long-term framework is not a sustainable solution and recommends that the government negotiates with First Quantum to establish a new framework that can address the outstanding arbitration proceedings and provide for a restart to support an orderly, self-financed, long-term closure process, all while complying with the ruling of the Supreme Court of Justice and prioritizing environmental, social, and economic outcomes for Panama. The report highlighted the findings of the independent environmental audit, which found a high level of compliance while identifying a limited number of areas for improvement, which we have already commenced addressing.

The report also recognizes the significant economic consequences of the shutdown for Panama, from employment and local business activity to export and government revenues, and indicated that economic activity previously generated by the mine cannot be easily replaced by other sectors. Importantly, the Commission highlights the severe impact on communities around the mine and recommends that these communities be priority beneficiaries in any future framework with greater local economic participation and tangible investment in community needs. I would also like to provide some context around the Commission's comments on closure. The report recognizes that closure for the site of Cobre Panamá's scale is a complex engineering and environmental undertaking involving ongoing tailings and water management, rehabilitation, stabilization, and long-term monitoring to ensure a high-quality outcome for environmental rehabilitation, biodiversity, and local communities.

The report does not describe closure as a single event but as a long-term process that needs to be properly planned, funded, and independently verified. As such, rather than an immediate closure that would place a high burden on the state of Panama, the Commission recommends a progressive closure over several decades that would be funded by the mine's own economic activity. The Commission also recommends that the mine's territorial footprint does not expand and be progressively reduced through closure and rehabilitation over the life of the operation. The ministers have explained that the ultimate territorial footprint needs to be smaller than that was agreed under Law 406. As a reminder, the Commission's report expressly states that it is setting out general principles and that mechanisms and other specifics are to be developed through negotiations.

We view the report as a positive step forward towards establishing a basis from which formal dialogue can begin. We remain ready to engage constructively with the government of Panama, with the objective of a fair and durable solution for all parties while respecting Panama's sovereignty, ownership of its reserves and resources, democratic institutions, and legal processes. Thank you, and I will now pass the call to Rudi to discuss our operational results.

Rudi Badenhorst
COO, First Quantum Minerals

Thank you, Tristan. Quarter three brought another quarter of production growth, supported by continued strong performance from S3 at Kansanshi and the continued processing of stockpiled ore at Cobre Panamá. Approximately 109,000 tonnes of copper were produced in the third quarter, an increase in total copper production compared to the second quarter. Copper sales totaled 110,000 tonnes, which was approximately 1,000 tonnes above production, assisted by Cobre Panamá volumes that were carried over from the second quarter. At Kansanshi, copper production in the quarter was approximately 46,000 tonnes, up 2,000 tonnes from the previous quarter due to improved throughput. S3 was sustained above design capacity owing to higher operating time and strong utilization and milling rates. Also, at Kansanshi, we actively managed leaching by prioritizing lower acid-consuming material when acid consumption rates were high.

This generated 70,000 tonnes of surplus sulphuric acid sales during the third quarter, allowing us to realize additional value from the strong pricing environment, which Ryan will discuss. Copper production guidance for 2026 has been narrowed to between 175,000 and 185,000 tonnes, and gold production guidance has been lowered to between 95,000 and 105,000 ounces, both reflecting performance to date. While S3 is expected to continue to operate above design capacity, stripping at Southeast Dome is taking longer than originally planned, which will result in lower grades continuing into the next year. Additionally, the acid sales initiative is expected to continue into 2027, which will also impact copper production. At Sentinel, copper production was approximately 49,000 tonnes, a decrease of about 1,000 tonnes from the previous quarter, with lower grades more than offsetting improved throughput.

The lower grades reflected the areas mined during the quarter, with access to higher grade mining areas delayed due to the lower mining volumes as a result of the mid-life overhaul of Rope Shovel one. Grades and throughput are expected to improve in the fourth quarter of 2026 as mining progresses with stage 2, with the reintroduction of shovel one, deployment of a new, larger hydraulic face shovel in October, and the introduction of the relocated In-Pit Crusher four that was out of operation for the entire quarter three. Production guidance at Sentinel for 2026 has been updated to between 190,000 and 200,000 tonnes of copper to reflect performance to date.

We remain effective in managing the maintenance of bolt fatigue issues and continue to plan for a major upgrade regarding the flange bolt fatigue at Ball Mill 2 in 2027, which will involve replacing a section of the discharge end with a new original equipment manufacturer design, which will provide a permanent engineered solution. As Tristan noted, good progress has been made on the processing program at Cobre Panamá, which is now transitioning from recommissioning to stable operations. During the quarter, copper production was over 13,000 tonnes, and gold production was over 6,000 ounces. Additionally, we resumed concentrate shipments in the third quarter. 33,000 wet metric tonnes of copper concentrate was loaded and shipped in August, demonstrating the restoration of the site's processing and export capabilities. A second vessel with approximately 39,000 wet metric tonnes was loaded and shipped in September. Processing of stockpiled ore is progressing smoothly.

We had 38 million tonnes of stockpiled ore at the beginning of the program, with sufficient stockpiles to support processing until mid-2027. We remain on track for guidance for 2026, with copper production from the stockpiles expected to be 30,000-40,000 tonnes and gold production expected to be 10,000-15,000 ounces. Enterprise produced just under 10,000 tonnes of nickel, a 13% decrease from the previous quarter due to lower grades, following stronger grades in the first half of the year. Ore grades are expected to be lower in the fourth quarter, in line with the mine plan. However, mining volumes are expected to increase in the fourth quarter with the arrival of additional contractor equipment, and production guidance for 2026 has increased to between 40,000 and 45,000 tonnes of contained nickel following strong performance to date.

Following expansion of the ore footprint, our operational priority will now focus on rainy season preparation. This includes installation of the in-pit dewatering stage tank and final development of the main pit sump, which is due to be completed before the start of the upcoming wet season. Similarly, with the ROM ore pad nearing capacity, ore feed to the nickel concentrator is well set up for the rainy season.

Lastly, looking at Guelb Moghrein, copper production was 1,000 tonnes and gold production was 16,000 ounces, which includes output from reprocessed tailings to the CIL plant and all stockpiles treated via the flotation circuit. Copper production guidance for 2026 is approximately 7,000 tonnes of copper. However, gold production guidance has increased to 45,000-50,000 ounces following the successful transition to a gold-focused operation. Thank you. With that, I will turn the call over to Ryan for the financial review.

Ryan MacWilliam
CFO, First Quantum Minerals

Thank you, Rudi. LME copper prices remained strong in the third quarter, reaching record highs of $6.74 per pound. Market volatility increased in September due to the uncertainty surrounding U.S. tariffs. However, underlying fundamentals remained supportive, with supply constraints compounded by weather disruptions and strikes in Chile. Our financial performance was strong this quarter. Revenue increased by 37% to $2.1 billion, driven by higher copper prices and increased sales. This revenue included two concentrate shipments from stockpile processing at Cobre Panamá. In Zambia, our integrated smelter production ensures security of acid supply for our SX/EW operations and provides additional surplus acid to sell. Zambian acid prices have increased from $180 per tonne in the first quarter to $460 per tonne in the third quarter.

Due to the strong acid pricing environment, we sold 70,000 tonnes of acid in the quarter, which generated $33 million of revenue and provided a 14 cent by-product credit to our copper C1 costs. EBITDA more than doubled quarter-over-quarter to $844 million. This was driven by elevated revenues and the benefit of full exposure to copper prices, as we have no further hedges in place. Turning to costs. Excluding Cobre Panamá's stockpile processing, copper C1 costs of $2.40 per pound were eight cents lower quarter-over-quarter. This was driven by lower fuel and maintenance costs and increased acid sales. This more than offset the impact of Guelb Moghrein transitioning to a gold operation, where the corresponding accounting treatment results in the gold production no longer counting as a by-product credit. Including Cobre Panamá, copper C1 costs were $2.59 per pound, up five cents quarter-over-quarter.

This reflects a 13 cent per pound impact from full quarter of stockpile processing at Cobre Panamá. As expected, we continue to see elevated diesel prices during the quarter, averaging $1.40 per liter, though a modest decrease from Q2 average of $1.59 per liter. With a two to three-month lag in fuel deliveries, elevated fuel prices will continue flowing through the cost base for the rest of the year. Turning to guidance. We have updated our copper C1 guidance to $2.50-$2.65 per pound, incorporating the previously provided sensitivity of 25 cents due to elevated fuel prices and a stronger Zambian kwacha. These inflationary pressures are expected to continue to impact our cost base into the new year. All-in sustaining cost guidance has increased to $4.10-$4.25 per pound, primarily reflecting higher royalties associated with stronger copper prices and the impact of lower production volumes.

Enterprise nickel cost guidance is revised down to $3-$3.25 per pound due to the strong operational performance at that mine. Finally, total capital expenditure guidance has been narrowed to $1.15 billion-$1.25 billion, reflecting the latest timing assumptions on CapEx. We have previously estimated that stockpile processing at Cobre Panamá would cost $250 million. Our latest estimate is $200 million, of which $80 million has already been spent. On the balance sheet, net debt improved by $98 million to $5.3 billion, with strong EBITDA generation sufficient to cover our planned CapEx, tax, and interest outflows. Our net leverage ratio improved to 2.6 times, marking our lowest level since Q3 2023 before the suspension of production at Cobre Panamá. We remain focused on deleveraging and expect strong copper prices and continued free cash flow generation to further strengthen the balance sheet.

Overall, it was another solid quarter, with strong operational performance and higher copper prices underpinning robust margins. I will now hand the call back to Tristan Pascall.

Tristan Pascall
CEO, First Quantum Minerals

Thank you, Ryan. As I attended the London Metal Exchange week two weeks ago, one theme came through very consistently. The world faces a growing scarcity of new. Despite the near-term macroeconomic and geopolitical volatility out there, in the medium and long term, the world will need to meet growing demand. However, bringing on meaningful new production will be challenging with few large-scale, high-quality greenfield copper projects in the pipeline due to decades of investment. This constrained supply outlook underscores the optionality and value of First Quantum's greenfield pipeline and the decades of experience we have in delivering growth. Based on measured and indicated resources, our portfolio includes two of the world's largest undeveloped greenfield copper projects in Taca Taca and La Granja. At Taca Taca, we continue to work constructively with provincial authorities with the mine ESIA approval expected this year following public consultation, which has been scheduled for November.

We expect water use concession approvals to follow, and we are preparing our RIGI application for submission shortly. At La Granja, the engineering study is well advanced alongside environmental baseline work, community engagement, and resettlement planning. We continue to advance engineering definition and permitting work while preserving flexibility around the ultimate development approach. A technical report on reserves is expected to be filed in 2027. We will approach both projects with the same core team that built Sentinel, Cobre Panamá, and most recently, the S3 expansion at Kansanshi. Over the last 20 years, this core team has completed $13 billion in capital projects, including two of the world's largest greenfield copper projects by initial throughput capacity. There have been valuable technical and financial lessons learned that will not only guide us in how we design and build these projects, but also how to fund these projects in a disciplined manner.

This experience positions us well in the long term to deliver the next generation of large-scale projects at the right time. In the meantime, we have made meaningful progress on our priorities thus far this year, and our near-term focus remains firmly on execution of them. Firstly, a fair and durable resolution for Cobre Panamá. Secondly, safe, reliable, lean, and productive performance at our operations. Thirdly, continued proactive management of our balance sheet to ensure flexibility to invest in the future. And fourthly, de-risking our growth pipeline with the discipline needed to deliver long-term value. The improvement we saw in our third quarter results demonstrates the underlying potential of First Quantum's business. We still have work ahead of us, but I remain confident in the business and our ability to execute on our priorities that will progressively unlock optionality and further value.

With that, operator, I'm happy to open the line for questions.

Operator

Thank you. We will now begin the question and answer session. At this time, I would like to remind everyone in order to ask a question, please press star followed by the number one on your telephone keypad. If you would like to withdraw your question, press star one again. We ask that you please limit yourself to one question and one follow-up to allow everyone an opportunity to ask a question. Our first question comes from the line of Orest Wowkodaw with Scotiabank. Please go ahead.

Orest Wowkodaw
Analyst, Scotiabank

Hi, good morning. A question about Kansanshi. Your disclosure talks about delays in stripping the southeast dome, which I guess has impacted the grade profile for this year. Your release alludes to a knock-on impact into 2027. I am wondering if you can give us more color there. How long is it behind? Is it three or six months behind? Can you give us a sense of the grade impact on the sulfide circuit for 2027?

Tristan Pascall
CEO, First Quantum Minerals

Hi, Orest. Thanks for the question. Yes, so that is right. Where we would want to be, we are not quite there. So we are just headlining that. In terms of this year, we do not see much impact, and you see that in our guidance. But we are saying that we see that challenge into next year. We will come back to that, and there is a lot of focus on how that can be achieved. We will come back to that in our guidance in January, February.

Orest Wowkodaw
Analyst, Scotiabank

But can you give us an indication, is it three months behind, six months behind? We do not have any sense here.

Tristan Pascall
CEO, First Quantum Minerals

Yeah. Thanks, Orest. We'll work on that and come back to you. This year, there won't be much impact, and we'll come back to it in our guidance next year.

Orest Wowkodaw
Analyst, Scotiabank

Okay. Thanks.

Operator

Our next question comes from the line of Richard Garchitorena with Barclays. Please go ahead.

Richard Garchitorena
Analyst, Barclays

Great. Thank you, and congrats on a good quarter. My question is on following the recommendation from the Interministerial Commission. Can you walk us through what the next milestones are in terms of the government process? Obviously, the president has to make a decision. But what are the, I guess, commercial, legal, and environmental issues still need to be resolved? And then also, if you do get some go-ahead, what's the current timeline for you to ramp up once you get the approvals?

Tristan Pascall
CEO, First Quantum Minerals

Yeah. Thanks for the question. I think first thing to note is that the recommendations were absolutely in line with moving forward and dealing with the situation at the mine over the long term, and that requires reactivation. We would look forward to engaging on that in a formal manner. I think right now, the focus in Panama is in relief efforts around the earthquake. I think certainly for our team, but more broadly in the country, that's really the importance. That's going to take, we believe, some weeks to ensure that everybody that's been affected by the earthquake is in a good position. I think at the right time, the matter of the mine will come back to focus with government. In that regard, the next step we see clearly is an announcement following the recommendations, which were to the president to negotiate.

We expect that to be, "Okay, well, thank you for the recommendations, and the instruction is to proceed as per the recommendations." We would look forward to engaging at that time in a formal manner around negotiation. In terms of what that will require, yeah, certainly there's three key elements. The legal structure, I think it's been made clear that we expect to have a different pathway under the Constitution, and certainly we will be constructive around that. The important side of that is there's transparency about what that will be and what it will look like, and people understand it well. Secondly, on the environmental sides, following up from the environmental audit and the Supreme Court of Justice saying that there needed to be an ESIA update, that that's addressed and that there's a consultation around that process in order to have transparency.

Thirdly, on the commercial terms. In that side, and you ask around that, it's just too early to say. We will look forward to discussion around that, but we see that there's a need for balance between, obviously people in Panama are saying there needs to be more tangible benefits locally and the benefits of the mine to come through. Equally, that this is the largest investment in Panama's history and there needs to be recognition of that, in preserving the country's reputation as a destination for investment. So that's broadly across it, and again, we look forward to the announcement at the right time that there will be formal conversation, formal negotiation, and we certainly from our side at First Quantum, we will engage constructively to find the best result for all stakeholders.

Richard Garchitorena
Analyst, Barclays

Great. Thanks for that color. Just maybe on the copper costs, obviously it increased from 240 to 250 to 265. I was wondering if you could bridge how much of that was related to the higher kwacha, the higher fuel, and Cobre Panamá volumes increasing. Maybe break it down for us if you could. Thank you.

Tristan Pascall
CEO, First Quantum Minerals

Thanks. Thanks, Ryan. Can you take that question, please?

Ryan MacWilliam
CFO, First Quantum Minerals

Sure. You saw about a $0.13 impact this quarter with Cobre Panamá coming online, but we would note our previous guidance already assumed Cobre Panamá included in it. We added that in in Q1. So the $0.25 we have added to the guidance is purely due to cost impacts. As you note, that is diesel and kwacha. The kwacha represents about 20% of our cost base is in kwacha, and we have seen that obviously strengthen significantly from just under 30 to just under 20 over the last year. And then similarly on diesel, a big step up in costs. We were procuring it around $0.80 in Q1. We have now been procuring as high as $1.60 in Q3. And as a result, we have baked that $0.25 in. It is broadly 50/50 impact split between kwacha and diesel.

Operator

Our next question comes from the line of Alain Gabriel with Morgan Stanley. Please go ahead.

Alain Gabriel
Analyst, Morgan Stanley

Yes, thank you for taking my question and good morning and good afternoon, everyone. First question is back to Cobre Panamá. How realistic is it for the discussions to address the three buckets that you have laid out, Tristan, within the next seven or eight month timeframe that you have laid out until you fully exhaust the stockpiles? And how will you practically run the operations if the timelines slip by a few months? That is my first question.

Tristan Pascall
CEO, First Quantum Minerals

Yeah. Thanks, Alain Gabriel. Certainly, those three areas are the key focus. And we have done a lot of preparation work in regard that in terms of each of the elements, and have a good understanding of the path forward there. We do need to engage and have a clear picture from governments as to where their priorities are. But I think coming through the recommendations, we start to see a clear picture. But that will take time to get through. As you say, yes, we feel good about the concrete milestones that have been made, and we continue to act in good faith on both sides. So the arbitration was put aside and certainly First Quantum has been committing in terms of keeping the asset in good standing in terms of its environmental condition. We were investing $13 million- $15 million a month.

Now that we are in the processing phase of the stockpiles, we are able to cover that cost, which was important, but ensure that we continue to rehabilitate the site. On the government side, we have seen clear milestones around the enactment of the Preservation and Safe Management plan, the export of concentrate into restart of the power plant, and then the start and completion of the environmental audit. And now the Interministerial Commission's recommendations, and with the stockpiles in process. And yes, we have a timetable around that, but we feel that it is the right thing to do to ensure that people have a good training program ahead of them. So we continue to look at whether it is the right thing to do to bring on the second train, in order that people have a good understanding around the mine, the employees and people are ready. The community is ready.

But we will need to go through that negotiation process. Certainly, from our side, we will be constructive in seeking resolution as soon as possible.

Alain Gabriel
Analyst, Morgan Stanley

Thank you. That is clear. And the second question is back to Taca Taca as well. You continue to advance the ESIA and the water permits, and plan to submit the application on the RIGI, as you mentioned. Can you remind us of the timelines and how rigid are your balance sheet metrics or guardrails that you set in enabling you to sanction the project? And what are your preferences in terms of capitalizing the project when you compare minority stake sales to partnerships, Vicuña style or simply outright debt financing?

Tristan Pascall
CEO, First Quantum Minerals

Sure, Alain. Let me handle the first part and then I'll ask Ryan to take the second part of the question on the financing. In the milestones, they're very clear. There are four main milestones for us. Firstly, the ESIA and there will be a public consultation in November, and at this stage, we continue to see the progress of that in due order, and we would expect resolution shortly within several months inside this year. The second will be the RIGI application. We've been drafting that to make sure that that's a high-quality application. We're conscious of the due date by July 8 next year, and so we'll be submitting that shortly. Thirdly, the financing, which you reference, and Ryan can speak more on. Fourthly, when do we get to a decision?

As you point out, we will be fiscally disciplined, economically disciplined around that. We said publicly we'd like to see our net EBITDA ratio fall towards one, and at this stage it continues to decrease. With the strong third quarters in a very good position right now. But we'll continue to focus on that, and that's important in terms of making sure that the balance sheet's in a good position alongside the financing pathway that we've been developing. Ryan?

Ryan MacWilliam
CFO, First Quantum Minerals

Yeah. It's pleasing, as Tristan notes, to see the progress on the balance sheet at 2.6 times net debt to EBITDA in Q3. But to be clear, we still have a way to go. We're going to be disciplined around targeting that region of one times net debt to EBITDA before project sanction. In parallel, we'll work on financing options. We've noted that strategically, we're open to partnerships across our asset base as we work more with others. That includes, we'll explore those options at Taca Taca. It would be a minority stake if we go that route, so we can put our project execution capabilities into the asset. But there are also a variety of other options available to us that we'll explore. The asset has very strong by-product credits, so streaming is one avenue. Project finance is certainly another avenue we're working on.

We announced the consultation agreement with IFC earlier this year, which supports project financing. It's really about giving ourselves a variety of options and then assessing which option is the most attractive from a cost of capital perspective and also a strategic perspective. That's some of the work ahead of us, over the next period in advance of project sanction.

Operator

Our next question comes from the line of Cody Hayden with Deutsche Bank. Please go ahead.

Cody Hayden
Analyst, Deutsche Bank

Yes, good afternoon, and thank you for taking my question. Just going back to Kansanshi very quickly. You are currently processing lower acid-consuming material to maximize acid sales. I was wondering if you could give us a bit of color on the strategy and the potential for acid production volumes in Q4, and then how this strategy could potentially impact copper production into 2027. Thank you.

Tristan Pascall
CEO, First Quantum Minerals

Sure. Ryan, can you take that question from Cody?

Ryan MacWilliam
CFO, First Quantum Minerals

Yeah. Cody, as you know, we have seen a very strong acid market as a result of the situation in the Middle East, prices averaging over $400 in Q3. As a result, we processed slightly less of the low-margin copper, around 1,000 tons of copper production that we sacrificed, which resulted in us generating 70,000 tonnes of acid, which we sold and which in turn realized $33 million or $0.15 by-product credit on our C1 costs. We expect to continue to sell acid into Q4 and next year. We have taken a slightly more conservative assumption in our Q4 guidance. We assume sales around 45,000 tonnes through the balance. Certainly at any acid price above $200, we will continue to look to sell excess acid. If we see those prices continue into next year, that will mean slightly lower copper production.

We've seen it have about a 1,000-ton impact per quarter, as we note in Q3. How much of that we end up realizing or pushing forward on will really be dependent on how the acid market evolves over the next 12 months.

Cody Hayden
Analyst, Deutsche Bank

All clear. Thank you.

Operator

Our next question comes from the line of Ian Rossouw with Barclays. Please go ahead.

Ian Rossouw
Analyst, Barclays

Thank you. Just another question on Cobre Panamá. You previously mentioned just around the expectations of, I guess, when you have the decision to restart the operation fully, ramp up to, I think you said 80% within the next six-n ine months. Just, I guess, now that you've commissioned all the trains, whether you can update us on that. And I think longer term, you said it's always just, I guess, it will be dependent on whether you can get the full employee sort of complement and I wanted to just get an update how that's going.

Tristan Pascall
CEO, First Quantum Minerals

Yeah. Hi, Ian. That remains right. What we see, and I think as you saw in the decrease in costs, we are saying around the rehabilitation from $250 million down to $200 million. The asset is in good condition. It has been well looked after during the periods of shut. Most of the work was in really man-hours in painting and welding and reconditioning, and we continued to work our way through the back end of the plant, particularly in columns and the concentrate areas. At the front end, yes, the three trains are in position. During the quarter, we largely completed the SAG mill segment change-out on train three. All of that work does come to bear in terms of performance.

From here, we do think we continue to hold to that timeline for ramp-up to the levels that you describe, 80% or so in six to nine months. Really that comes down to the mining side of things. We have no drill and blast. We are operating around seven trucks in a circuit, although we have put 18 trucks of the total into service at this stage. We need to go through all the trucks and then have all the operators and train them all up for a full mining operation. We think that is where the time will be in getting up that six to nine months.

Beyond that, it will take a lot, as it always has done, in getting to full nameplate capacity in terms of optimization of Cobre Panamá, having the screening plant running, all of those elements on the journey towards 100 million tonnes per year.

Ian Rossouw
Analyst, Barclays

Thanks. Then maybe just to follow up on that, I think previously you said $350 million- $500 million, including the $250 million, which you have now reduced to $200 million for a full restart. Is that still a relevant number? How should we think about the spending of that? Is some of that front-loaded as you ramp up the material movement?

Tristan Pascall
CEO, First Quantum Minerals

Sure. Ryan, do you want to comment on that?

Ryan MacWilliam
CFO, First Quantum Minerals

Yes. So again, we previously said $250 million for the stockpile restarts, and then another $250 million once we get the formal green light to move back into operations. As you note, we expect to underspend the first $250 million at around $200 million, but there is no change to our assessment that on the full green light, we will spend another $250 million split between building up working capital, some CapEx, and then the commissioning costs as we move up to move back into full operations.

Operator

Our next question comes from the line of Matt Murphy with BMO Capital Markets. Please go ahead.

Matt Murphy
Analyst, BMO Capital Markets

Hi, can I try another one on production outlook on Sentinel? What work have you done in terms of understanding how long the ball mill will be down for next year, and is that captured in the guide already?

Tristan Pascall
CEO, First Quantum Minerals

Thanks, Matt. Rudi, can you take that question?

Rudi Badenhorst
COO, First Quantum Minerals

No problem, Tristan. Hi, Matt. Hope you're doing well. Yes, the can replacement on ball mill two in train two is scheduled towards the middle part of next year. It is part of our plan, and the budget is part of guidance already. It's important to note that although the estimate for replacement of that section of the back end of ball mill two will take between 30 and 40 days, it is not a full stoppage of the train two at Sentinel. SAG mill will continue to run with the entire train one milling circuit. So it's just a slight reduction in throughput as a result of not having that ball mill available, but it does not really impact on our overall production guidance for next year. We're well advanced in setting up for that.

We're just waiting for the last remaining bits to be delivered to site, and then we'll get cracking.

Got it. Okay. Thank you for that, Rudi. Then also just one on the Zambian kwacha for cost implications. I guess we've seen it weakening a bit from the highs early in Q3. So I don't know what your crystal ball says on Zambian kwacha into next year. Is that something you would hedge, or do you have any views on whether it's going to potentially be a tailwind next year?

Tristan Pascall
CEO, First Quantum Minerals

Sure, Matt. Ryan, do you want to take that question? With your crystal ball.

Ryan MacWilliam
CFO, First Quantum Minerals

Yeah. I'd say crystal balls on global exchange rates are normally pretty foggy, Matt. I'd hesitate to predict the Zambian kwacha. What we see is in the more risk-off market that you've seen over the last quarter globally, you've seen that hit emerging markets currencies, and the Zambian kwacha certainly hasn't been spared in that regard. It does provide a slight tailwind on our costs through the quarter, but it's too early to say. As we think about our planning, we plan at around somewhere between the 18- 20 kwacha to the dollar, and we don't foresee any step change on that over the next year. But certainly, we'll monitor that. And we don't look at hedging.

I'd say the kwacha market, one, is not a very liquid market to hedge, and secondly, we're always very cautious on hedging exchange rates in general, given you can then be squeezed if you don't hedge the top line. At this stage, we're pleased to be unhedged across both our revenue lines and our cost inputs, and it's our expectation we'll continue to be that way into the new year.

Tristan Pascall
CEO, First Quantum Minerals

I'd just add, Matt, that we've seen the outcome of the election, and I think that the market recognizes the continuity that's there. So far, what we're hearing and in terms of the projection around appointment of ministers and so on is a good level of continuity. So we continue to see Zambia being a good destination for investments, and that underlines the strength of kwacha as well as the points around Ryan's making. Overall, we see that as very positive for the country. We see that the performance that's been there will continue on, and we're certainly leaning into that in terms of the next period of time.

Our next question comes from the line of Myles Allsop with UBS. Please go ahead. Myles Allsop, your line is now open.

Myles Allsop
Analyst, UBS

Oh, sorry about that. I was on mute. Just going back to the Interministerial Commission report, what did you find the most surprising in that report? Obviously, the share price reacted pretty aggressively. Then just maybe you could clarify in terms of how long were you originally expecting Panama to operate for. Was it 25 years or longer? The footprint as well. Of the current footprint, how much has been moved versus untouched, if that becomes an issue in terms of constraining production in the future? That's the first question.

Tristan Pascall
CEO, First Quantum Minerals

Thanks, Myles. Yes, certainly what we saw in the recommendations were establishment of the conditions for a long-term closure, and that involved reactivation of the mine, and central to that is negotiation to resolve the arbitration, but also to ensure that the people around the mine and the recommendations noted very clearly that those around the mine had been most impacted to ensure the continued strong stewardship of the environment. All of those need to come to bear. In terms of the surprises on the day, certainly, there was a lot of activity, but it's a reminder to sort of read the document rather than react to headlines or to post headlines at the front end. Certainly we saw a lot of machine trading kick in as it triggered stop losses and so on. On not much volume, there was a big movement.

But again, the written down clear elements of the recommendations were fairly straightforward, and for us, clearly continue the pathway to resolve this matter in a constructive way, and we continue to work on that. Then, sorry, Myles, the first part of your question, what was that?

Myles Allsop
Analyst, UBS

Just around how long were you planning originally for Cobre Panamá to operate for, and the footprint that has been disturbed by the mine so far if you are constrained by not being allowed to use the full lease?

Tristan Pascall
CEO, First Quantum Minerals

Sure. Look, we will just need to clarify that further in the negotiations. We note that comment in the recommendations, and it is part of what we will have to understand and discuss with government.

Myles Allsop
Analyst, UBS

Okay. How long was Cobre Panamá originally planned to operate for? Was it 25 years? I mean, the resource, I presume, would last a lot longer.

Tristan Pascall
CEO, First Quantum Minerals

Yeah. The original ESIA, which was for the three main pits, and then with the reserves and resources around there was around 32 years, but then at the higher throughputs rates, it came back a little bit. That is the order of magnitude of the previous basis of approval. Looking into the future, it is obviously prospective around the area, but they were not in the original ESIA approval.

Operator

Our next question comes from the line of Anita Soni with CIBC. Please go ahead.

Anita Soni
Analyst, CIBC

Hi, thanks for taking my question. Just to follow on with that, just to clarify, the Commission has recommended that it's just what was included in the original ESIA approval, right? You can't go out past that? The mine life is now 25 years and no extensions?

Tristan Pascall
CEO, First Quantum Minerals

No, Anita. Hi. Thanks for the question. No, the recommendation didn't give a timeline. It just gave a worked example, and I think we're speculating here around timeline as to what will be involved. It did recognize that the resolution would take time, and to reactivate, and we'll need to get into a negotiation to understand how that works.

Anita Soni
Analyst, CIBC

There's still some optionality for further phases besides what's included in the ESIA?

Tristan Pascall
CEO, First Quantum Minerals

The minister said pretty clearly that the ultimate footprint needs to be smaller than that was agreed under Law 406, and we will need to see what that is as we engage in conversation and negotiation.

Anita Soni
Analyst, CIBC

Okay. My actual question was just, have you engaged with Franco-Nevada at this point, and what their stance is given the Commission's recommendations? I would have thought that they were probably looking for some further upside in their original investment in Cobre Panamá. I am just wondering if you have had any discussions with them post the Commission's recommendation.

Tristan Pascall
CEO, First Quantum Minerals

Thanks, Anita. Franco-Nevada are an important part of this in resolving the matter. They are part of the capital markets investment into Panama alongside our partners, KORES. All of that is how the overall global capital markets have put the money into the investment for Cobre Panamá, and all of us have a key role in resolving the matter constructively going forward.

Operator

Our next question comes from the line of Chris LaFemina with Jefferies. Please go ahead.

Chris LaFemina
Analyst, Jefferies

Hi. Thanks, guys. Just another question, sorry, on Panama. This idea of operating the mine to self-fund a long-term closure, I mean, I guess that's kind of true for all mines around the world, but I'm wondering if there's anything specific that we should take away from that. Does it imply that you'll have to keep restricted cash in the country to fund the closure? I mean, obviously, this is something you're still going to be negotiating with the government, but what could that mean in terms of how you ensure funding without Panama having to commit any capital along the way, restricted cash or investments in Panama or something, or just do we not know yet?

Tristan Pascall
CEO, First Quantum Minerals

Thanks, Chris. I mean, the headline here is, I think, comparing it to if there was a walk away today, what the liability would be and how the state of Panama would address that. Ryan, could you just answer any further detail there?

Ryan MacWilliam
CFO, First Quantum Minerals

Yeah. Chris, there are obviously a variety of ways in which that could be achieved, through guarantees or closure funds or cash reserves. The principle outlined is that the closure needs to be responsibly funded and that funding needs to be protected for. In terms of which mechanic the government will look to put in place to achieve that, we'll have to wait for that detail when we get into those negotiations, and we'll approach those negotiations constructively because we too are aligned with the government that we want to see responsible provisions for closure in due course.

Chris LaFemina
Analyst, Jefferies

That makes sense. Thanks. Secondly on Cobre as well. Tristan, you mentioned earlier the earthquake, which is obviously a priority for the government now, and I'm just wondering what sort of delays around negotiations that could imply. I mean, I remember it was last year when social security reform was a priority for the government, and they would get to the mine after that, and now we're in the process of hopefully getting the mine back online pretty soon, and then the earthquake unfortunately happens. Are we thinking about, I think you might've mentioned weeks rather than months for delays around that, but how should we think about that? Thank you.

Tristan Pascall
CEO, First Quantum Minerals

Thanks, Chris. Look, it did have a significant impact. Thankfully, no large loss of life in Panama, but it has affected. We had 19 employees that we are supporting who have lost their homes. It is certainly had an impact, particularly in Penonomé seems to be one of the areas most affected, and ensuring that those people have relief is correctly the right focus of the government right now. There is a lot of effort going into that, and that is important. We see that the matter of the mine will come back. I think the holiday season in November in Panama around the public holidays for independence are probably a key element in that timeline. We will just see which side of that it comes down to.

Operator

Thank you. That concludes our Q&A session. I will now turn the call back over to Tristan Pascall for closing remarks.

Tristan Pascall
CEO, First Quantum Minerals

Thank you, operator, and thank you everybody for your time and for joining us today. I hope you enjoy the rest of your day. Thank you.
