Intrinsic Value is all-important and is the only logical way to evaluate the relative attractiveness of investments and businesses.
Good morning. My name is [ Adriana ], and I will be your conference operator today. At this time, I would like to welcome everyone to the Lundin Mining First Quarter Results Conference Call. [Operator Instructions] Thank you. I would now like to turn the call over to your host. Marie Inkster. Please go ahead. .
Thank you, operator, and thank you, everyone, for joining Lundin Mining's First Quarter 2020 Results Call. As always, I would like to draw your attention to the cautionary statements on Slide 2. We will be making several forward-looking statements throughout the course of this presentation and likely in the Q&A as well. On the call today to assist with the presentation and answering questions are Jinhee Magie, our Senior Vice President and Chief Financial Officer; and Peter Richardson, our Senior Vice President and Chief Operating Officer. Through our prepared remarks, we will be focusing on the quarterly results and our current outlook. We recognize that there is continuing interest in our readiness and response to COVID-19, and we'll be happy to answer any questions in detail during the Q&A to specifically address our activities in this regard. At Lundin Mining, safety is 1 of our 4 fundamental values and is always at the core of our business decisions. COVID-19 is a global threat, which requires a united response from governments, industry and our communities to ensure the safety, health and well-being of all. Each of our operations are continuing to manage and respond within the framework of the company's pandemic response plan, recommendations of health authorities and local and national regulatory requirements. Corporately and at each operation, we continue to identify and implement measures to protect our workforce and our communities. Across Lundin Mining, we are taking numerous steps to ensure needs are being addressed in the communities and regions in which we operate. We are sharing action plans and the preventative measures being taken with our employees, unions, contractors, communities and industry peers, while seeking and considering their input to ensure we are delivering responsive actions consistent with broader efforts. Further, we are actively providing support in the form of community donations of emergency funding, essential supplies and numerous other forms. The photos on this page demonstrate some of the basic measures being implemented in the coordination with government and local health authorities to protect our workforce and our communities. There are numerous other measures we are taking. Just 1 example is our Candelaria, where we have provided an air-conditioned construction trailer to help local authorities conduct effective roadside health checks. I would like to acknowledge all of the Lundin Mining employees and our contractors who are working tirelessly and have risen to many challenges to keep our operations running and, most importantly, safe. COVID-19 is impacting the way we operate. But we will strive to continue delivering on our mission to responsibly mine base metals vital to society, delivering meaningful value to all of our stakeholders. And now I'll turn the call over to Jinhee to look at our summary financial results. Jinhee?
Thank you, Marie. Looking at a summary of our results on Slide 4. Our operations in aggregate produced over 112,000 tonnes of base metals and approximately 38,000 ounces of gold in the first quarter. We sold over 101,000 tonnes of payable base metals and approximately 39,000 ounces of gold, generating revenue of $378 million.The quarter's revenue was significantly impacted by negative provisional pricing adjustments given the decline in the market price of many of the metals we produce. The negative impact on revenue was $63 million for prior period adjustments and $86 million in total or $0.12 per share, including mark-to-market of current period sales.Additional information on our provisional prices and personal adjustments is included in our MD&A in Note 12 of our financial statements. 64% of our revenues were generated from copper. Gold contributed an increase of 15% to overall revenue, with the contribution of unencumbered gold production from Chapada and the strong gold price. Zinc, nickel and lead contributed a combined 21% to total revenue. Slide 5 presents a summary of the quarter's financial results, the details of which are in our financial statements and MD&A issued last night. First quarter revenue was 9% below that of the same quarter last year, in part owing to lower metal prices and negative price adjustments as discussed. The price decline was offset by higher copper, nickel and gold sales volumes mainly due to the acquisition of Chapada and increased production from Candelaria. Gross profit was significantly lower, reflecting the decline in revenue as well as inclusion of Chapada production and depreciation, amortization costs and increased amortization of the first stripping at Candelaria with mining in Phase 10 of the open pit. Attributable loss from our operations was $0.15 per share. First quarter net loss was negatively impacted by the gross profit as discussed at $62 million or $0.08 per share of deferred tax expense at Chapada arising from foreign exchange translation, which has no cash impact. Adjusted loss was $0.06 per share for the quarter. Details of the adjusted loss are in our MD&A issued last night. Despite the negative provisional pricing adjustments, we generated EBITDA of over $90 million in the quarter. Cash flow from operations was $83 million and adjusted operating cash flow before changes in noncash working capital was $28 million or $0.04 per share. First quarter capital expenditures on a cash basis were $141 million. We will discuss more details of CapEx later in the context of reducing this year's overall capital expenditure guidance by 30%. We ended the quarter in a strong financial position with $367 million in cash and equivalents, net debt of $118 million and a further $430 million available under the company's revolving credit facility, excluding the $200 million accordion. In March, the company drew down $150 million on the revolver and took out an additional term loan at Candelaria as precautionary measures to protect against economic uncertainty. This is reflected in the increase in the debt position this quarter. Yesterday, our Board of Directors declared a regular quarterly dividend of CAD 0.04 per share or CAD 0.16 per share on an annualized basis, maintaining the increase announced last quarter. We remain in a strong financial position with ample liquidity and minimal financial leverage. I will now turn the call back to Marie to discuss our operations and projects.
Thanks, Jinhee. On Slide 6, Candelaria had a good operating quarter, particularly in the context of implementing operating changes to protect our workforce and communities from COVID-19. Production was impacted by ore hardness and available operational hours of the SAG mills, which limited the mill throughput. While we work to minimize the impact of the mill optimization project in the quarter, construction interferences and other operational downtime affected mill throughput more than planned. We have now completed upgrades on 3 of the 4 ball mills. On the line where both ball mill upgrades have been completed, we are seeing the expected performance increase of finer grind and increased recoveries. Optimization work continues. Overall, construction was approximately 87% complete on the Candelaria mill optimization project at the end of the quarter. We have postponed the upgrades on the fourth and final ball mill given the restrictions arising from COVID-19, limiting the ability to safely mobilize contractors and consultants. The expected completion of the mill optimization program in the second half of the year assumes that we will be able to safely mobilize the necessary personnel and coordinate with the planned no maintenance shutdowns. Ore hardness is expected to decrease beginning this quarter through the remainder of the year and is considered in our revised production guidance. We have widened the copper production guidance range for the year, maintaining the high end with a modest reduction at the low end. We've modestly revised gold production as well. Aggregate site operating costs were below planned for the quarter owing primarily to the favorable exchange rate. The Chilean peso USD average was 8.02 versus our plan of 6.75. Full year cash cost guidance has been improved to $1.35 per pound of copper from $1.45 per pound. The majority of the decrease owes to a more favorable exchange rate assumption. With the majority of our operating cost, Chilean peso denominated and driven. Lower diesel price and electricity price assumptions also contribute to this. Candelaria's sustaining capital expenditure guidance for the year has been reduced by approximately 13% to $230 million. Of this, approximately $150 million remains with $77 million capitalized in the first quarter. Capitalized stripping is expected to be lower mainly due to the deferred volume as well as the lower mining costs. Also included is deferral of some underground mine development and technology implementation as well as some drilling equipment. 2020 was already a low CapEx year for Candelaria compared to the previous 2 years average of greater than $400 million per year. 2020 exploration expenditure guidance has been reduced to $15 million from $20 million, the $5 million reduction is related to the drilling and drifting. Candelaria has long mine life already ahead in the proven and probable mineral reserve category, owing in large part to our significant and successful exploration programs over the last several years. Candelaria is positioned to deliver over 30% production growth by 2021 over 2019 with improving cash costs. Moving on to Chapada on Slide 7. Chapada also had a good operating quarter, particularly again, in the context of implementing the operating changes and reducing the number of people on-site to protect the health and safety of our workforce and communities. The mine performed well during what turned out to be a very heavy rainy season and mill throughput was above plan. Gold production was impacted by poor recovery, which has since improved to levels comparable to the fourth quarter of last year. Full year copper production guidance has been maintained, while gold production guidance has been moderately reduced to reflect the first quarter results. Copper cash costs were better than planned, benefiting primarily from a favorable foreign exchange rate and from strong gold prices, which improved the realized byproduct credit. The majority of Chapada's operating costs are Brazilian real denominated. It was slightly above and averaged 4.46 versus plan of 3.75. The gold price averaged $1,583 per ounce, and while this is still well below current pricing, it was significantly better than our plan of $1,350. Full year cash cost guidance has been improved to $0.85 per pound of copper from $1.15 as a result of the more favorable foreign exchange and gold price assumptions. Capital expenditure guidance for Chapada has been lowered by approximately 33% to $40 million, approximately $4 million was capitalized in the first quarter. Roughly $7 million of the reduction is related to capitalized stripping, reflecting both a lower expected stripping ratio as well as exchange rate benefits. Discretionary exploration, land acquisitions have also been deferred. The remaining significant items are small project deferrals and some mine equipment replacements. The 2020 exploration expenditure guidance has been lowered modestly from $7 million -- to $7 million from $10 million previously. In responding to COVID-19, the exploration program has been reduced in the short-term to minimize the number of employees and contractors on site. We have brought some drilling activities back on and are planning on how to increase drilling again as the situation allows. Approximately 40,000 meters of drilling is planned for the year from 50,000 meters previously, with the majority of this to focus on near-mine targets. Approximately 5,400 meters were completed in the first quarter. We believe there is significant value to be created at Chapada through expansion at the appropriate time. The study work is ongoing. As we have indicated previously, the expansion strategy will be underpinned by the exploration success that we can achieve. Moving on to Neves-Corvo on Slide 8. The operation had a challenging quarter, particularly in March, with a significant number of employees working from home and a large number of contractors suspended for COVID-19 risk mitigation measures. The Zinc Expansion Project was temporarily suspended and the workforce demobilized. Zinc production was as expected, with plant throughput, head grade and recovery, all in line with plan. Copper production was impacted primarily by below-planned head grade. Mining in lower-grade ore zones, in particular, lower grade ores from the Corvo ore body, had a large impact on the copper grade and less on metal production. Aggregate site operating costs were better than planned before our favorable exchange rate. However, on a cash cost basis, these benefits were negatively impacted by lower copper production levels and zinc by-product pricing, resulting in a Q1 cash cost of $2.24 per pound of copper. Full year copper production guidance has been reduced, reflecting the first quarter results. Zinc production guidance has been revised to reflect production from current operations only due to the uncertain timing of the restart of the ZEP. We are also reviewing potential impacts on the 2021 zinc production estimates. Copper cash cost guidance has been revised to $2.10 per pound, $1.80 previously reflecting reduced zinc by-product production and lower pricing assumptions. Capital expenditure guidance has been reduced by $120 million or 52% to $110 million. The majority of this reduction, $100 million, reflects the temporary suspension of the Zinc Expansion. The Project advanced very well during the quarter, on track for the phased start-up and production during the year prior to the temporary suspension in mid-March. $55 million is forecast to be capitalized on the ZEP this year on a cash basis. A little under $31 million have been capitalized during the first quarter, which means $24 million over the remainder of the year. This relates mainly to payment for work that has already been completed and continuation of some minor works. Sustaining capital expenditure guidance has been reduced by $20 million to $55 million, approximately $16 million was capitalized in the first quarter. The majority of the deferral relates to mine development as well as underground drilling, mobile equipment and other smaller items. The 2020 exploration program has effectively been curtailed with expenditure guidance lowered to $2 million from $7 million previously. First quarter expenditures were approximately $1.2 million, and no additional drilling is presently planned for the year. I will now turn the call over to Peter to review the Zinc Expansion progress up to the suspension date as well as the performance for Eagle and Zinkgruvan. Peter?
Thanks, Marie. We continue to make good progress advancing the ZEP project in the first quarter. In fact, surface construction had recorded the highest monthly progress rate to date prior to the temporary suspension. Slide 9 shows some of the progress achieved. At the end of the quarter, the underground aspects of the project were 88% complete. Civil and mechanical works were largely complete. Development of lower stopes were advancing as planned with the first 2 sub-level accesses continuing. The 2 pictures on the left show the #2 transfer tower and crusher chamber nearing completion. Surface construction was nearly 80% complete with the materials handling and the SAG aspects more than 98% complete. The photo in the middle right shows initial SAG mill commissioning work in progress and the photo on the right shows how advanced the flotation circuits were preparing for commissioning as well. On Slide 10, the Eagle mine and Humboldt Mill performed well during the quarter. In response to COVID-19, we have modified our procedures at Eagle in accordance with state and local health recommendations. Approximately 45% of our own employees at Eagle on a daily basis are working from home in order to improve physical distancing. Development of Eagle East was fully completed 13% under the original cost estimate and a full month ahead of schedule. As mining progresses into the higher-grade regions of the Eagle East ore body, grades are expected to increase. We are currently processing notably higher nickel grades, and these will be variable throughout the year. The first quarter cash cost of $1.43 per pound on nickel was in line with plan despite lower by product copper price. Full year nickel and copper production, C1 cash costs and capital expenditure guidance have all been maintained. Eagle 2020 nickel production is set to increase more than 3,000 tonnes or 22% over 2019, a reduced cash cost as higher-grade Eagle East ore continues to contribute to the mill feed. Similarly, copper production is expected to increase more than 2,200 tonnes or 15% this year. Eagle remains well positioned to generate meaningful free cash flow even in the current metal price environment. Lastly, Zinkgruvan, on Slide 11. We have modified work arrangements to reduce the number of people on sites, enhancing sanitation regimes and implementing several changes to improve physical distancing. We are implementing many of the preventive and health measures at Zinkgruvan that we are at other operations. During the first quarter, Zinkgruvan achieved excellent performance in the mine and mill. So zinc production was negatively impacted by the zinc grade. We have re-sequenced mining of several stopes due to temporary ground stability considerations. The rescheduling, unfortunately means pushing out mining of some higher-grade zinc stopes until later in the year and a lowering of the expected average zinc grade for the year. Aggregate and per tonne mill costs were better than planned in the quarter, even before the impact of favorable foreign exchange rates. The increase to cash cost guidance relates primarily to the decrease in zinc production as well as to an assumption of lower lead by-product credit. 2020 capital expenditure guidance has been lowered by $5 million to $45 million. This includes deferral of some mobile equipment as well as elimination of small projects and foreign exchange benefits making up the balance. Approximately $8 million was capitalized in the first quarter. Exploration efforts continued in the quarter on existing ore bodies from underground as well as targeting Dalby deposits [ on certain ]. Full year expenditure guidance has been reduced to $7 million from $15 million. Geophysical surveys and some drifting activities have been deferred. Planned drilling has been reduced to approximately 17,000 meters from 60,000 meters previously. I will now turn the call back to Marie.
Thanks, Peter. We have discussed the revisions to our production and cash cost guidance in each of the operations sections and in detail in our MD&A. This table provides a summary of the current guidance. As we have noted, our operations have not experienced significant disruptions to production, shipment of concentrate or supply chains as a result of COVID-19. However, we have reassessed the production in light of the temporary suspension of the Zinc Expansion and operating procedures implemented to reduce the risk of infections at our sites. Further, cost reduction programs have been implemented to respond to the low metal price environment. Similarly, Slide 13 provides a summary of our capital and exploration expenditure guidance. We have discussed the revisions in previous operational sections and in detail in our MD&A as we had with the call. Our 2020 capital expenditure guidance has been reduced by $180 million or over 30% to $440 million as a result of the temporary suspension of the Zinc Expansion and cost reduction programs implemented to respond to the low metal price environment. Planned exploration expenditures have been reduced by 36% or $20 million to $35 million with focus remaining on near-mine targets. Our assets, which have active exploration programs, all have long mine life ahead of them and proven and probable mineral reserves. This reflects successful exploration programs over the last several years. We do not expect the deferral of exploration expenditures to have a significant impact on the near or medium-term mine plans. We believe there remains significant value to be created at our operations through exploration. We will ramp up these programs with consideration given to health and safety and economic conditions. Turning to Slide 14, a familiar slide, but with slight modification this quarter. From our current assets, we continue to have an excellent growth production profile now benefiting from previous significant investment initiatives over the last few years. We continue to guide for over 30% growth in attributable copper production from our current assets from 2019 to 2021, the growth is primarily attributed to realizing the benefits of the low risk, high-return investments we were making over the last 2 years and are nearly complete, at Candelaria, in addition to the Chapada acquisition. With the temporary suspension of the Neves-Corvo zinc project, we are currently reviewing the 2021 and 2022 zinc production forecast. The addition of Chapada has increased our gold production and more importantly, has significantly increased our attributable and fully exposed gold production to nearly 100,000 ounces this year based on our current guidance. Lastly, nickel production is set to increase as the higher-grade ores of the Eagle East are mined. Before opening the line for questions, I would like to reiterate a few key points on our strategy and advantageous position. We aim to operate, upgrade and grow our base metals portfolio that provides leading returns for our shareholders throughout the cycle. We believe a copper dominant portfolio, coupled with other well-positioned base metal mines, and precious metal by-products will continue to enable the best returns throughout the cycle. Assets with a competitive cost position such as ours, reduce the real and perceived risks of potential curtailment in the trough of the cycle while offering leverage and ability to create meaningful value through the up-swing. We aim to maintain low leverage and a flexible balance sheet while increasing direct shareholder return. It's difficult to predict when the cycle may turn and as it often does so quickly. Operating with low leverage and a flexible balance sheet has positioned us well to navigate the economic impact of the pandemic while maintaining direct shareholder return. And with that, operator, I would like to open the lines for questions.
[Operator Instructions] First question comes from the line of Orest Wowkodaw with Scotiabank.
Orest here from Sotiabank. I was wondering if we can get a bit more color on Neves-Corvo. When I look at your revised [indiscernible] guidance, it would imply essentially no growth from 2019 levels. Does that does -- does that imply that you're effectively assuming that the ZEP is delayed until the end of the year?
Yes, that's correct. And we've taken out the ZEP from the 2019. And we've assumed that we're not going to restart in our base case plan. We have assumed that a restart is not until January 1. And there are a couple of reasons for this. The first being that we could try to bring it back in the summer or another time. And -- but at the moment, we feel there's a risk that we will have to curtail again if there's a second wave of COVID. And so we don't want to remobilize and have to do a partial or full demobe again. We think that would be really value destructive. And plus, right now, with zinc prices where they are. We're not in any screaming rush to bring on zinc when TCs are as high as they are and the price is as low as it is. So if we can preserve then defer that $100 million that we still have left to spend in a low zinc price environment, we think that's a prudent thing to do.
I see. And I realize you're still reviewing your operating plans then for '21 and '22, but is kind of the right way to think about it is just basically take the old mine plan, push it back a year as a rough guess?
I wouldn't necessarily say a year, maybe 9 months, if you want to be conservative then a year. Peter, what would you say? I think we need 3 months of ramp up on the -- essentially, what we were going to start in March, we'll start on Jan 1, according to the current plan.
Okay, that's correct Marie.
The next question comes from the line of Dalton Baretto with Canaccord Genuity.
My first question is on what Marie touched on in terms of the FX rates of diesel and the implications on the cash cost. Marie, have you moved to lock in some of these exchange rates in Chile and Brazil as well as the diesel prices?
We have not, although I know Jinhee has been looking at this with the sites, in particular, with Candelaria on some of them. I believe that the cost to lock in the price is more than compelling. Jinhee, do you want to give an update on that?
Sure. So Candelaria and Chapada both have long-term contracts on the diesel. We are -- and we have been looking at kind of hedging and locking in some prices. But at this point, we didn't find it compelling the cost of the hedging and locking in the pricing to be compelling at this point, but we will continue to assess.
Yes. I think it's not helpful, Dalton, that they want all the payment upfront, and they want major upfront payments and a lock in on price much higher than we have right now in the market.
Okay. That's helpful. And then maybe one question on provisional pricing here. I mean, it's just -- it adds an unnecessary element of volatility here. Can I ask what your rationale is for not hedging out your exposure during the quotational period?
Yes. That's something that we have never done. We have always stayed naked on our exposure on metal prices. And we always get the question as to why we don't do it when the prices go down, and we always get praised for not doing it when the prices go up. So our position and our policy is to not hedge our metal exposure.
Okay. And then maybe just one last one for me. The CapEx deferrals, presumably, these are either necessary or higher risk -- or higher return projects, I should say. So just given your balance sheet, why did you feel the need to actually defer some of these?
It's a little bit about discipline Dalton. I mean, some of the things that we have kept in there, for example, the mobile crusher, we have kept in there for Chapada because it is a high-return project. That easily could have been shelved. A lot of the deferral as well will have to do with the fact that we have restrictions on contractors right now, and we've cut back significantly the number of contractors that can come to our site. And especially if they're traveling from other regions. So if you're doing an improvement project that requires a specialist consultant to assist in the implementation of something new, you're not going to be able to bring them to site. So some of those things have gone by the wayside. Some things we're just looking prudently and asking the sites that they take extra special care because of the low metal price environment and that they implement some cuts in order to preserve their cash flowing -- the cash flow at the sites. And we have a good plan. We have been able to cut without hurting the future production. And I think it's prudent. And there's nothing there that is a really high-value item that we haven't considered leaving in.
Next question comes from the line of Greg Barnes with TD Securities.
The SAG mill operational hours issue at Candelaria. Was that all just related to CMOP? Or was there something else going on there that caused that issue?
No, we did have some challenges with the ore hardness. Peter, do you want to elaborate on that?
Yes. So the throughput issues, I would say about 65% were to do with CMOP and other operational issues and 35% of the loss was due to ore hardness. But we did have some complications during the CMOP work on the third ball mill motor upgrade. But also other operational issues during the quarter that we have resolved.
Okay. So that is fully reversed, I guess, going into Q2?
Yes.
And Marie, just on drilling at Chapada, you slowed that down, but you're still continuing the studies on the expansion scenarios for the operation. But is this slowing down what kind of decision timing we could think about so when you would come out with some view on what you're going to do at Chapada?
Well, the reason we slowed down initially, it wasn't for economic reasons or a need to preserve cost. It was because we looked at what are the simple things that you can curtail at the moment in order to reduce the number of people at site and the number of visitors to site. And the exploration was an easy one where it didn't affect our production and you could reduce the number of people at site. So that was really a COVID-19 response. At many of our sites, we did reduce the exploration programs initially as a COVID-19 response. And we're already looking at how we ramp that back up and bringing people back to get the drills turning again. We have proceeded with the desktop studies. I can't say for certain how it will affect the timing of the final decision, we had been kind of thinking of an 18-month kind of time frame. And if we don't get the drilling that we need, maybe we may delay that by a couple of months, but it's hard to say right now.
The next question comes from the line of Jackie Przybylowski with BMO Capital Markets.
I know you guys have gone through a lot of the detail already. So I'll just ask a couple of quick ones. Firstly, on the NCIB, I know in Q1, you did buy back some shares. I was wondering if you could maybe talk a little bit about what your thoughts are given the current environment if purchasing on the NCIB is the high priority for you right now?
Yes. So we did talk about the capital allocation and whether -- how we look at capital return during a quite low metal price environment, and if we end up having any suspensions due to outbreaks at our mines. So we ran a number of scenarios, and we're fairly happy with the 30- and 60-day suspension scenarios at any of the mines or all of the mines. We're still in fine shape. But we decided that we would probably not prioritize the NCIB, but that we wanted to maintain the dividend, and there's no reason why we shouldn't be maintaining the dividend given our financial strength. So right now, we are proceeding with caution on the NCIB, but have maintained the dividend.
That makes sense. Maybe just -- this is probably a dumb question, but I noticed on your -- on your Q1, the taxes at Chapada were pretty high. Can you give me a little bit of a color as to why they were high in Q1 and maybe what we can expect for the rest of the year?
Yes, not a dumb question at all, and this is -- Jinhee has heard me rant about this tax in Brazil that kind of drives me crazy the ups and downs. But Jinhee, can you elaborate on that for Jackie?
Sure. Absolutely. Jackie, it's not a dumb question. We're just joking about how the accountants and the CSAs, we don't understand it really either. But it is very much an accounting-driven thing. So at Chapada, because our financial reporting currency is in USD, but our taxes are filed in Brazilian real. When we are calculating our deferred taxes, we have to actually retranslate our USD balances on our net assets back to Brazilian real. So what this does is it changes the cost base in the local currency which then raises a deferred tax. So in Q1, where we had a weakening Brazilian real, it basically translated into higher local currency amounts. And that drove the deferred tax liability and the deferred tax expense. So I guess just on the expectations going forward, it's really hard to predict what that's going to be because it really does depend on the Brazilian real to USD FX relationship. So as it continues to weaken, then we'll continue to see some additional expense. If it strengthens, then we'll see a recovery on that in the future.
The next question comes from the line of Oscar Cabrera with CIBC.
Marie, as you are undergoing the revision of the Neves-Corvo Zinc Expansion. If I remember correctly, this project was first came about because zinc prices were expected to go above $1. In your comments or in the first question, you mentioned higher TC. So just wondering if you could help us think through this, like with the project coming back at the beginning of January, are you thinking about any type of rationalization? Is also a point in time where copper was being processed through the zinc [ segue ]. Is there anything you can do right now, understand that some cost is there, but how are you thinking about it?
I'm not -- I kind of missed a little bit of the question there, Oscar, but in terms of the -- it's a balance between the TC and the price. The TCs have an impact on the metrics as well. And when we're looking at, say, I think a $10 increase in the TC is going to have, if you have 100,000 tonnes, then that's going to be $1 million difference, right. So it's -- we always look at the TCs and also whether there are escalators in the payables and the TCs and those are important. But the price also is important. The reality for Neves-Corvo is that it will be better for productivity and for the fixed cost coverage if we have more production. So I think ultimately, the Zinc Expansion Project is a project that will help the mine be more profitable. And it's something that we need to embark on at the right time. But for the time being, there's no rush to bring on the zinc when the prices are so low. And if we're in cash preservation mode, it makes sense to suspend that since we've had to demobilize because of COVID-19. I don't know if that answers the question or not.
Yes. No, it does. It does. So I guess, if there has to be further suspension, you just give us an idea of what remobilizing the site would cost? And if you could lower the zinc production? Or is it better just to fully utilize the expansion?
Yes. So I guess that those are things that we look out on a continuous basis, and we continue to study and Neves-Corvo, of all of our mines, that one has the lowest margins typically. And we've challenged the site to study what they can do to improve that. And so we're always looking at ways to improve and the optimal mix. In the future, it may not be having all of the mills full at all of the time. It may be some lesser number, but to get a better recovery or better quality. So those are things that we continuously look at when we do our planning and life of mine plans every year as well.
Okay. That's helpful, Marie. And then on your cost, I wonder if you could comment, it just seems the vast majority of the reductions in both Candelaria and Chapada have to do with the foreign exchange. But is there a way to quantify how much of that reduction was that and -- or higher by-products?
Yes. The -- for Candelaria, there wouldn't have been a big change in the by-product because a lot of our gold is streamed. But say, for example, at Chapada, typically, 70% to 80% of our costs might be in the local currency. So you can go on that basis. Whereas at Candelaria, maybe it's 60 to 70. So I think those would be typical ranges for costs in the local currency. But we also did have a benefit from those 2 sites from the diesel price as well. So say, for example, Candelaria at $50 a barrel, we might have a $30 million cost. If it's much lower than that, you can extrapolate down.
Okay. So if things were to stay, the economic slowdown would continue, is there more in the system where you can take out more cost and what would the trade-off with production be?
Yes, there are definitely things that we can do to take out costs, and it's a question of what -- how far do you want to go? And what would your mine plan look like in the future years? Because most of the cost that'll be meaningful to take out is going to be in OpEx -- or sorry, in Capex. And it's the deferred stripping in the underground mine development, where you're going to cut back on contractors, you're going to cut back on those things. And it won't interfere with you keeping the mills running. I mean, we could park all the trucks at Candelaria and run off the stockpiles and the same thing at Chapada. But then we're not doing the development we need to go forward. And those are scenarios that we run. If we did have a very distressed metal price environment, those are things that we would look at doing.
The next question comes from the line of Lawson Winder with Bank of America.
So I just wanted to go back to Chapada and Brazil. And just on the alarming number of COVID-19 cases in the country and just sort of dig down a little bit on your contingency plans there. And just ask sort of what would give you confidence that you could potentially keep running there? And also, I wasn't sure if you might have the ability to keep employees on-site there for an extended period of time and sort of isolate the mine, if that might be another option as opposed to suspension?
In Brazil, well, a lot of our workforce lives in the local town, which is -- there are 2 towns that are less than 10 minutes from the site. So we don't have the facilities to isolate people on-site because they're close to the major centers, so we don't have any kind of camps or anything like that. We are watching very carefully the developments in Brazil. We do notice the cases are increasing. And right now, within 100-mile radius of the mine, there's one confirmed case that we're aware of in a town called Campo Norte, and it's a truck driver who works in another town who is not associated with the mine who is currently isolated. We've done a number of things there in order to try to protect people. There's education programs as well as all the things that we're doing at the sites, which lots of different things, including limiting visitors. We've changed our protocols on visitors, travel. We are -- we have temperature checks at the mine gate now. We have mandatory quarantine for people who may have had incidental contact or exposure. We've changed a lot of our work processes, reduced the amount of contractors at site significantly. So we've taken all of the steps that you would expect that we would take in order to reduce the risks. That doesn't eliminate the risk, it reduces them. So in the event that we did have an outbreak and had to have a shutdown, we would -- we do have shutdown plans and contingency plans for that. At each of our sites, we have pandemic response plan and have outlined emergency shutdown plan. And also in Brazil, we've been in contact with the authorities. We've sent them information on what we're doing to safeguard the people at the site. And we've had good feedback that they're very satisfied with that. So all we can do is continue to be diligent and continue to try to reduce the risk to our people and respond when and if we do have an exposure.
Okay, Marie. Also on Chapada. Would you have any additional comments on the lower gold recoveries there? And just why is it that they're now expected to improve into Q2? That would be great.
Yes, definitely because that's something we've been focusing on. Peter, do you want to elaborate on that?
Yes, I can elaborate on that. So first of all, the gold recovery in the first quarter was mostly due to lithology. So different spots and the -- we have 3 pits at Chapada. So different places and the pits have different recovery of gold. So we were mining in difficult areas and also some of the ore was from higher benches a little bit oxidized. So it did affect the gold recovery. We have seen late in the quarter, and we'll see the new gold recovery bounce back to normal levels. So that's something that we're expecting to go forward, and it's also captured in our forecast guidance.
Okay, great and then just one...
Sorry?
Sorry. No, go ahead, please.
So it's more related, as I said, to different lithologies, some of the different production areas in the mine.
Yes. No, that's great. Very clear. And then just one final one for me. You have it handy a breakdown of your cash balance, I think it was like a $357 million in terms of the various currencies, just so we get an idea of potential exposure there on translation risk.
Jinhee, do you have that handy?
Yes. We maintained most of our cash in U.S. currency. I would say about 80% in U.S. dollars. And then the rest of the 20% would be in, say, 10% or so in pesos and some in euros and Brazilian reals, just for working capital needs and purposes.
The next question comes from the line of Daniel Major from UBS.
Dan Major here from UBS. A couple of questions. The first one, we've heard from Antofagasta and other operators in Chile, in particular, that are running substantially reduced on-site workforce. And as you've mentioned lower levels of stripping development, et cetera. Can you give us a sense particularly at Candelaria, but also elsewhere, how much on-site labor is down? And how long the current sort of situation of partial restriction could last for before it would start to impact mine plans either in 2020 or 2021?
Sure. I'm just looking at the numbers from the most recent numbers of staff, we get updated every day. I don't have today's update, but I do have yesterday's, and we did have -- we still have 3,000 people working on site. And they're -- at Candelaria, I'm talking about Candelaria at the moment. We do have, call it, 250 working from home, another 107 in high-risk category, I guess, with some conditions that would make them high-risk if they did catch the virus. So they've been ordered to stay home to protect them. And we have 450-ish contractors suspended from the site. So in terms of order of magnitude at Candelaria, we don't have a huge amount of people away from the site in terms of the total workforce. But we have done a number of things that, I guess, would keep them from interacting with one another, such as changing the shift to schedule changes and changing the bussing patterns and cafeteria patterns and things like that. So for Candelaria at the moment, we can probably go on for quite some time as we are going. Where it would get concerning is where we have to do major maintenance stops and things where we need to have people coming from external like a specialist who will come to do certain types of maintenance and certain projects for us that aren't able to travel or can't come to site is something that we're watching. Similar with Chapada, we have probably about -- Peter, correct me if I'm wrong, 600 contractors have been temporarily put on suspension there. And that is mainly in the deferred stripping area and not in the production area. So obviously, we want to start doing that, or it will affect next year's mine plan. I think maybe 6 months of not doing it will probably not have a big impact. But beyond that, you want to get going and start doing those things. Those are the 2 big ones. Eagle in Marquette is working per normal, and we don't have a lot of people off-site, except for the people who can work from home who are still productive. Zinkgruvan, as you know, Sweden's taken a very different approach than the rest of the world. So it's business as usual in Zinkgruvan. And did I miss Neves-Corvo, we have a significant amount of people suspended from site at Neves-Corvo, doing underground developments on Lombador as well as surface works and a number of other contractors. So that is one site where we do have a significant amount of people off-site. And you've seen the impact that it's had on our plans where we've withdrawn our zinc guidance.
Okay. So I guess the conclusion to that is for now and for the next few months, at least, the current situation has no threat to the kind of plans you've laid out this year and next?
No. And you can see other than for zinc, we've reaffirmed our guidance on a 3-year basis.
Okay. And then second question is on the CapEx. The $180 million deferral. I guess, the $100 million ZEP is quite obvious. That's a direct deferral in terms of the $80 million of sustaining and the reduction in exploration spend, is it fair at this point to assume that you can catch most of that up in 2021, so we should be adding that to our CapEx estimates of 2021? Or will that be sort of spread over a number of years in terms of catching up on that that sustaining and development spend?
I think that will depend on the site because at some sites, there's only so much you can do in a year. So say, for example, Neves-Corvo underground development. If you defer it, you're just pushing it out by X amount of months because you're not going to suddenly double up the amount of underground development you do in a year. So that's more of a pushing it out rather than a catching it up, if that makes sense. And with the deferred stripping at Candelaria and Chapada, those are -- Candelaria, in particular, is a big number. We could catch that up potentially just by bringing on more contractors to do the stripping. So that's one where we'll have to make the decision about how much more we want to do next year. But I would say, I wouldn't just automatically add it in a [ walk ] to next year for the other sites other than Candelaria.
Okay. Got it. Useful. And then just final quick one, just catch it. What's the undrawn credit facility liquidity position at the end of the quarter. You've got the cash balance, which you've given and then what's the undrawn credit?
Yes. Jinhee, can you give that number?
Sure. The undrawn credit is about $430 million.
And that's without the accordion option, correct?
Yes, correct. We also have a $200 million accordion option on top of that.
The next question comes from the line of Ioannis Masvoulas with Morgan Stanley.
A couple of questions left from my side. The first one on Neves-Corvo and the ZEP project. If we were to fast forward 9 months and the zinc price is still where it is today and the expectations around the annual TCs is for a stable development. And assuming the COVID outbreak is under control, how would you feel about restarting the project on January 1 in terms of the overall economics of the project? And I'll stop there for the first question.
Well, the project still is a good project. And we plan to start -- to restart on Jan 1, according to our base case right now with the assumptions that we had in the Q -- in the quarter, which was, I believe, Jinhee $0.80 zinc and $2.25 copper?
Sorry, Marie, I was on mute. It was $0.85 zinc and $2.25 copper.
Okay. Yes. So our assumption is that those prices we would restart the project on Jan 1.
Okay. Understood. And then a second question around capital allocation. You mentioned that you have maintained the progressive dividend and you will progress on the NCIB a bit more slowly. Just putting into perspective, we've seen obviously a lot of volatility around metal prices, some risks to production across different sites globally. How do you feel about having a progressive dividend instead of having a payout ratio? And with regards to the NCIB, obviously, we don't have a lot of visibility on how that progresses throughout the year. We did not make more sense to think about, let's say, a special dividend that would give more visibility to investors on cash coming back to them.
Well, we're very comfortable with the dividend. We've run a number of scenarios, including 30- and 60-day shutdowns at the sites and where we can comfortably maintain our dividend at the prices that we just mentioned and with the temporary curtailments at any of the sites. The reason why we kept the discretionary part of the NCIB is for just this reason where there is uncertainty, we felt that we wanted to keep the discretion, which is something that we'll continue to do. In terms of a special dividend. I'm on the Board of another company who has done special dividends and while they're nice, they don't -- I'm not sure there's a long-term benefit to the special other than to some of the in and out short-term investors. The capital returns are good for the long term. But I think a steady, consistent, reliable dividend is something that we value and we think our long-term shareholders value and like to see. And it also provides us with some discipline in terms of knowing that we have to maintain a certain amount of liquidity, and that it's an important part of our capital return strategy. It impacts our decision-making, and we think it's an important part of our capital return program. Okay. It's 9:02. So let's have one more question if there is one.
The final question comes from the line of Stefan Ioannou from Cormark Securities.
Most of my questions have been answered. I guess just maybe just given your response to COVID, and I'm sure that's taking up the lion's share of your time right now and for good reason. But I mean, in the background, are there still -- is there still much thought going into potential sort of future growth strategy right now? Or is that kind of on the back burner just to address sort of the near-term sort of issues that you have to deal with already COVID and everything else?
Yes. We've kind of -- we're in a steady stay right now on the COVID response. We have our regular meetings and regular updates and the sites have done an exceptional job in managing. So we do -- we are focusing on the business other than just COVID-19. And that part is something that we're very active and maintain relationships. We're talking to lots of parties. And of course, getting calls from lots of bankers. The challenge right now is it would be very difficult to do something without being able to conduct site visits. So you can do desk studies until you're blue in the face, but with any mining asset, we want to be able to do the site visits and other things that you need to do in terms of diligence and things. But we'll continue to look at that. I don't think there's anything that stands out as if we didn't have a restriction, we'd be at the site now, that's not the case, but we are continuing to be active in looking at things. All right. Well, thank you, everyone, for listening in today. It was -- we wondered whether it work okay. Luckily, because of the rain, there's no leaf blower guys outside my window. And hopefully, next quarter, we'll be able to take the call from our offices as per normal. Thanks again.
This does conclude today's conference call. You may now disconnect.
