Peter Gerald Jan Kukielski - President, CEO & Director
Thank you, Candace. Good morning, everyone, and perhaps good afternoon and even good evening to some of you. Thank you very much for joining us. I wanted to begin by acknowledging the conflict in Ukraine. While it has exacerbated global inflationary pressures and supply chain disruptions, these impacts are inconsequential compared to the hardships and losses experienced by the many innocent civilians whose lives have been impacted by this very unfortunate situation. Our hearts go out to all of those affected.
In this presentation today, I'll give a brief overview of our first quarter financial and operating results, discuss highlights from our recent annual reserves and resources announcement and provide an update on the ongoing progress at Copper World and our other growth initiatives.
Before we dive into quarterly results, I wanted to congratulate a key member of our technical team, Matthew Taylor, our Executive Director of Metallurgy Technical Services. Last week, Matt received the 2022 Mineral Processor of the Year award at the CIM and CMP Society Ceremony. He was recognized for a significant mineral processing achievement relating to his work on the Snow Lake and New Britannia processing strategy with the implementation of a novel copper flotation circuit. We look forward to his continued contributions at our many growth initiatives, including Copper World.
Beginning on Slide 3. We maintained steady operations during the first quarter despite being faced with a number of external challenges, including COVID-related absenteeism, extreme weather conditions and inflationary cost pressures. This was a testament to our effective risk management systems and focus on operating efficiencies. And as a result, we have reaffirmed our full year production and cost guidance for 2022.
Our consolidated copper production in the quarter was 24,700 tonnes, in line with our expected quarterly cadence for the year as we anticipate significantly higher copper grades in Peru later this year. Consolidated gold production decreased by 16% compared to the fourth quarter primarily due to lower gold production in Peru as COVID-19-related absenteeism and high rainfalls limited production from the Pampacancha pits. Consolidated zinc production in the first quarter was 4% lower than the fourth quarter, primarily due to lower zinc grades at Lalor and 777.
Consolidated cash costs increased to $1.11 per pound of copper from $0.51 in the fourth quarter. This increase was a result of higher milling costs and lower copper production in Peru as well as higher general and administrative costs in Manitoba. Consolidated sustaining cash cost increased to $2.29 per pound in the first quarter compared to $1.95 in the fourth quarter due to the same reasons affecting cash costs, but partially offset by lower sustaining capital expenditures and capitalized exploration. Both measures were slightly above our 2022 guidance ranges, primarily due to lower by-product credits as a result of lower sales in Manitoba, which I'll provide more details on shortly.
Consolidated cash costs and sustaining cash costs are expected to improve in future quarters to be within the 2022 guidance ranges with higher expected copper production and contributions from precious metals by-product credits throughout the year.
First quarter unit operating costs were in line with 2022 guidance ranges at $12.37 per tonne in Peru and CAD 176 per tonne in Manitoba. This strong cost performance was achieved despite continuing to experience broad-based inflationary pressures caused by higher input prices for many services and consumables such as power, fuel, grinding media, freight and insurance.
Operating cash flow before change in noncash working capital was $77 million during the first quarter, reflecting a decrease from the fourth quarter, primarily as the result of lower copper gold and zinc sales volumes in Manitoba, partially offset by higher silver sales volumes and higher base metal realized prices. At the end of March, we announced that first quarter Manitoba sales were impacted by limited railcar availability. This resulted in excess inventory of about 7,000 tonnes of copper concentrate, which contains high amounts of gold and 6 million pounds of refined zinc at the end of the first quarter. Had the excess inventory being sold during the quarter, we would have realized approximately $45 million of incremental revenue, assuming end-of-quarter commodity prices. Our inventories are expected to be recognized as revenue and converted to cash as levels are drawn down over the next several months with increased railcar access as weather conditions improve.
First quarter adjusted net earnings per share was $0.02 after adjusting for a noncash gain related to the quarterly revaluation of the Flin Flon environmental provision which decreased as a result of higher long-term risk-free discount rates. First quarter adjusted EBITDA was $110 million lower than the previous quarter, primarily as a result of the lower sales volumes. We exited the quarter with $213 million in cash as well as undrawn availability of nearly $357 million under our revolving credit facilities. Given the elevated inventory levels in Manitoba at the end of the first quarter and the positive expected quarterly production cadence, our cash balance is forecasted to grow throughout the remainder of the year based on current commodity prices.
On Slide 4, we summarize our Peru operating results. During the quarter, our Peru business produced over 19,000 tonnes of copper, 10,800 ounces of gold over 500,000 ounces of silver and 207 tonnes of molybdenum. Production of all metals was lower than the fourth quarter, primarily due to a planned semiannual mill maintenance shutdown in January and lower grades. As previously disclosed, full year production in Peru is expected to benefit from significantly higher grades in the fourth quarter of 2022, and we have affirmed or reaffirmed our 2022 production guidance for Peru.
Total ore mined declined during the first quarter due to high rainfalls and COVID-related labor shortages which resulted in delays affecting the water management system and lower production from Pampacancha. Ore milled was lower than the fourth quarter due to the planned mill maintenance shutdown in January. Milled copper grades and recoveries were lower than the previous quarter, but were consistent with the mine plan. Milled gold grades and recoveries were lower than the previous quarter due to less ore from Pampacancha this quarter. With the rainy season now behind us in Peru, we expect Pampacancha ore production to return to higher levels in the second quarter.
Peru combined unit operating costs in the first quarter were within the guidance range, but higher than the fourth quarter due to continued inflationary pressures on consumables and energy costs and fewer tonnes of ore milled due to the planned mill maintenance shutdown. Despite these cost pressures, full year unit operating costs in Peru are expected to remain within the annual guidance range.
Peru's cash cost in the first quarter were $1.54 per pound of copper, higher than the fourth quarter, primarily due to higher milling costs and lower copper production. This was above the upper end of our 2022 guidance range, in part due to lower production and higher costs related to the plant maintenance in the quarter. Cash costs are expected to decline and full year cash costs are expected to remain within the 2022 guidance range with higher expected copper production and contributions from precious metal byproduct credits later this year. Peru's sustaining cash cost decreased compared to last quarter due to lower sustaining capital expenditures and lower capitalized exploration.
Moving to the next slide on Manitoba. During the first quarter, the Manitoba operations produced 43,200 ounces of gold, 22,300 tonnes of zinc, 5,500 tonnes of copper and 279,000 ounces of silver. Copper production increased by approximately 4% quarter-over-quarter, whereas gold, zinc and silver production decreased by 7%, 4% and 13%, respectively, due to expected grade variability and lower ore mill. Full year production of all metals in Manitoba is expected to be within guidance ranges for 2022.
Ore mined at the Manitoba operations in the quarter was lower than the fourth quarter due to employee absenteeism caused by COVID-19, unplanned maintenance requirements of the ore handling system that temporarily affected hoisting ability at Lalor and planned lower production on the 777 as the mine approaches closure in June.
The production ramp-up strategy at Lalor to achieve 5,300 tonnes per day by the end of 2022 is underway. It includes advancing development for new mining fronts, additions to the mine equipment fleet transition of workforce from the 777 mine upon closure and expansion of change house and office facilities.
A planned Lalor maintenance period has been advanced to the second quarter of 2022 to allow for increased availability during the third quarter after 777 has closed and the additional workforce and equipment have transitioned to Lalor. The 777 equipment relocation strategy will commence in the second quarter ahead of expected time frames to advance the production ramp-up to 5,300 tonnes per day. The 777 mine is within 1 month of closure and the focus continues to be on safely mining out the remaining reserves by completing the necessary ground rehabilitation to access remnant and pillar stoping blocks. Challenging ground conditions continue to cause delays in the production sequence and resulted in higher dilution than planned. These challenges are expected to continue until the end of the mine life in June. Pre-closure activities are well underway in mined out areas to decommission stationary equipment of value for redeployment at Lalor.
The New Britannia mill averaged approximately 1,400 tonnes per day in the first quarter, slightly below the targeted 1,500 tonnes per day as a result of completing scheduled rod mill liner maintenance during the quarter. Since completing the mill maintenance, new Britannia has consistently achieved greater than 1,500 tonnes per day in April with the inclusion of doré, the gold and silver recoveries of the new Britannia have also improved significantly with metallurgical recoveries in March higher in relation to previous months.
Additional initiatives are planned in the second quarter to further improve recoveries to be in line with targeted levels. Manitoba combined unit operating costs in the first quarter were within the guidance range, but 5% higher than the fourth quarter, primarily due to higher propane usage during the colder winter coupled with continued inflationary cost pressures for bulk commodities and fuel and lower tonnes processed. Full year combined unit costs are expected to remain within 2022 guidance ranges. With Manitoba's transition to a primary gold producing business, we introduced gold cash cost guidance and disclosure in 2022. Gold cash costs in the first quarter were $416 per ounce in line with our annual guidance range.
Late in March, we provided our annual mineral reserve and resource update. In Peru, mine planning gains and economic reevaluations resulted in additional mineral reserves at Constancia would largely offset 2021 mining depletion. Current mineral reserve estimates at Constancia totaled 521 million tonnes at 0.31% copper with over 1.6 million tonnes of contained copper. As a result, Constancia’s expected mine life has been extended by 1 year to 2038.
In addition, the Constancia Norte underground mineral resource estimates were added to Constancia’s Mineral Resources. A positive scoping study was completed in 2021, which resulted in an inferred mineral resource estimate of 6.5 million tonnes at 1.2% copper as shown on Slide 6. This resource estimate is in 2 high-grade skarn lenses located below the open pit in the Constancia Norte area. The study concluded these 2 lenses could be mined by underground methods starting in 2029 to supplement the open pit production. We intend to conduct infill drilling and an internal prefeasibility study in hopes of converting the underground mineral resources to mineral reserves for inclusion in the mine plan for the Constancia operations.
As a result of exploration success in Manitoba, additional mineral reserves were identified at Lalor and the 1901 deposit in our 2022 reserve update. This extended the mine life of the Snow Lake operations by 1 year to 2038 and maintaining the 17-year mine life. Resource to reserve conversion has more than offset 2021 mining depletion with a net gain for all metals including an additional 218,000 ounces of gold contained in reserves after adjusting for mining depletion.
This is a continuation of our successful year-over-year resource to reserve conversion in Snow Lake, where we have achieved a more than 350% increase in reserves identified to date, as shown on Slide 7. Inferred mineral resources at Lalor and 1901 increased by 1.1 million tonnes, bringing the total inferred mineral resources to 8.1 million tonnes. These inferred mineral resources have the potential to maintain the 5,300 tonnes per day production level in Snow Lake beyond 2028 and further extend the mine life.
Slide 8 highlights the progress we've made on several of our development and exploration growth initiatives. The key focus for Hudbay is our copper world project in Arizona. After the initial discovery in early 2021, we completed an aggressive drilling program, which led to an initial resource estimate in December 2021 and that is larger and at higher level of geological confidence than we expected at this stage. We also successfully expanded our private land package after the Copper World discovery and now hold over 4,500 acres to support an operation entirely on private land.
The initial technical studies for Copper World have been completed, and the results are being incorporated into a PEA contemplating the development of the Copper World deposits in conjunction with an alternative plan for the Rosemont deposit to capitalize on regional synergies. The PEA is expected to incorporate a 2-phase mine plan with the first phase reflecting a stand-alone operation utilizing our private land for processing infrastructure and contemplating mining portions of Copper World and Rosemont located on patented mining claims. The first phase is designed as an economically viable stand-alone plan, requiring only state and local permits and is expected to reflect an approximate 15-year mine life.
The second phase of the mine plan is expected to extend the mine life and incorporate an expansion on to federal lands to mine the entire Rosemont and Copper World deposits. The second phase would be subject to the federal permitting process. We expect the PEA to demonstrate positive economics for this low-cost, long-life copper project, and we look forward to publishing the results in a technical report in the second quarter of this year. In April, we commenced early site works at Copper World with initial grading and clearing activities taking place on our private land. We have also increased the number of drill rigs at site to 7 and to conduct infill drilling and to support future feasibility studies.
In addition to infill drilling, we continue to test regional exploration targets at Copper World. There remains several opportunities to further extend economic mineralization within the private land limits at Copper World and Rosemont, including to the north and south of Bolsa through drilling to bridge the gaps.
In Peru, drilling continues at the Llaguen copper porphyry target with over 9,000 meters drilled to date. Based on the positive results from the initial drilling, the second phase of drilling has been initiated, aimed at defining an initial inferred mineral resource estimate in the third quarter of 2022. In the Snow Lake region, we had a busy winter exploration program actively conducting surface and underground drilling activities. The program primarily focused on the copper-gold rich feeder zone at the 1901 deposit, the drilling gap between 1901 and lens 17 at Lalor and a high-priority geophysical target located immediately north of Lalor. We also commenced a confirmatory drill program on the Flin Flon tailings facility earlier this year to support the evaluation of the tailings reprocessing opportunity.
Slide 9 summarizes our upcoming catalysts. In Manitoba, we are advancing our Snow Lake gold strategy with plans underway to achieve 5,300 tonnes per day at Lalor by the end of the year as I touched on earlier. We are also implementing a recovery improvement program at the Stall mill this year to increase copper and gold recoveries as part of our Snow Lake gold strategy. We will continue regional drilling in the Snow Lake area to explore for base metal and gold upside, and we will continue to compile results from ongoing infill drilling programs at Lalor in 1901.
In Peru, we will continue to move discussions forward with the communities to the north of Constancia, working towards mutually beneficial exploration agreements on the highly prospective regional brands. In the United States, we expect to be submitting state-level permit applications for Copper World this year, and we continue to await the outcome of the Rosemont appeal decision from the Ninth Circuit Court. Following the publication of a positive PEA, we expect to advance a Copper World pre-feasibility study in the second half of 2022. And on our Mason property, we intend to launch an exploration program to test skarn targets later this year.
Concluding our presentation on Slide 10, a Hudbay offers leading near-term free cash flow growth and significant copper resource optionality through our high-quality organic pipeline. We believe that copper has the best long-term supply and demand fundamentals in the industry as global copper mine supply will be unable to meet demand from global decarbonization initiatives. We have the highest near-term free cash flow growth and the highest leverage to copper among our mid-tier base metal peers, and we have successfully increased our copper equivalent resources per share by more than 180% over the past decade. For these reasons, we believe Hudbay is uniquely positioned to offer attractive copper production growth and long-term optionality for investors. And with that, we're happy to take your questions.

(Operator Instructions) Our first question comes from Fahad Tariq of Credit Suisse.
Fahad Tariq - Research Analyst
Just first on the Manitoba railcar issues. I believe this isn't the first time that Hudbay has run into railcar issues. Can you talk a little bit about -- like are there ways to mitigate this going forward? Is this something that will happen seasonally kind of every year? Any comments there would be helpful.
Peter Gerald Jan Kukielski - President, CEO & Director
Sure,. Thank you very much for the question. Look, yes, it is a seasonal phenomenon. But given the intensity of the phenomenon this year, we have looked at mitigating that through additional railcars in the coming year. So we do expect to be able to mitigate this going forward.
Fahad Tariq - Research Analyst
Okay. And then maybe just switching gears on Copper World, the PEA -- in your news release, you talked about litigation that's been brought forward relating to water on the private land. It sounds like it doesn't really apply. But I'm just curious if that's changed the way you're thinking about the PEA that you're thinking about the phased approach in any way?
Peter Gerald Jan Kukielski - President, CEO & Director
No, no. And that's certainly a good question. Look, 2 groups of opponents have provided notices of their intent to see Hudbay arguing that Copper World contains waters of the United States, and Rosemont requires a 404 water permit to advance the project. The federal permitting agency, Army Corps of Engineers in charge of water permits has never determined that there are waters of the United States on Hudbay's private land, and we performed our own analysis that shows there are none. So the work we're currently doing at site is grading and land clearing activities on our wholly owned private land and no federal permits are required for these activities. Does that answer your question?
Fahad Tariq - Research Analyst
Yes, it does. Okay. So there's no change in the plan based on this Okay. And then just my math -- and my last question, we've been waiting for some time now in the Rosemont ruling. It was supposed to be end of 2021. We're now almost halfway through 2022. Can you just give any insights if you know what kind of holding up the decision?
Peter Gerald Jan Kukielski - President, CEO & Director
That's an interesting question. And in fact, we have no insights whatsoever into what is holding up a judgment by the Ninth Circuit Court. We have, for a long time now, expected an outcome imminently, and we continue to expect that outcome imminently, but we have no insight into when that might be.
Fahad Tariq - Research Analyst
Okay. And then can you just remind us if you were to get a favorable ruling, does that change your approach in any way? Is it still -- would it be the same approach, prioritizing Copper World in conjunction with Rosemont and then more Rosemont in Phase 2? Or would any of that change if you got a favorable decision?
Peter Gerald Jan Kukielski - President, CEO & Director
No, none of that would change in the event of a favorable decision. But maybe perhaps I could sort of just expand on that a little bit. Judge Soto's decision in 2019 resolved only 1 key issue from the 2 related lawsuits, namely the plaintiff's argument about the mining law. So a reversal by the Ninth Circuit Court would result in the case being remanded back to Judge Soto to resolve the remaining claims in those lawsuits. And although we don't feel that they would justify a full injunction on their merits they do remain a source of potential other delays. And we would also need to still obtain a revised biological opinion from the Fish and Wildlife Service and a new record of decision from the forest service before restarting construction on Rosemont.
So there would be a number of factors that you would have to reevaluate and review that will be required for the project to restart. So bearing all that in mind, there's quite a bit of work to be done potentially. And by far, the most sensible approach is to proceed as we're planned with Copper World.

Our next question comes from Orest Wowkodaw of Scotiabank.
Orest Wowkodaw - MD & Senior Equity Research Analyst of Base Metals
I wanted to ask about Peru and Pampacancha specifically. It seemed like you were delayed accessing ore there in the first quarter. And given that you were already expecting sort of Q4 to be the highlight of the grade profile in terms of that feeding through the plant. Can you talk about if you see any risk to that high-grade ore slipping out of this year into perhaps early next year? Like can you catch up is what I'm trying to get at.
Peter Gerald Jan Kukielski - President, CEO & Director
Thank you for that question. Look, as we indicated, we were impacted by the rainy season. That rainy season is over. And also the other impact was based on COVID absenteeism in the first quarter, which sort of reached a very, very high level in January and February, but that has now completely gone away. So things are progressing very, very well. Weather has improved. We expect to be back to full mining rates in the pit by June. And we do believe that we're on track to achieve the expected higher grades in the fourth quarter. Of course, there is always some risk, but we are pretty confident that we will be able to meet the mining requirements to do that. Andre, would you offer any additional comments to that?
Andre Taylor Lauzon - Senior VP & COO
No, no. I think you covered it well, Peter.
Peter Gerald Jan Kukielski - President, CEO & Director
All right. Good.
Orest Wowkodaw - MD & Senior Equity Research Analyst of Base Metals
And do you have the ability -- I mean, given most of the tonnage is still coming from the main pit, do you have the ability just to put more equipment at Pampacancha to catch up if you need to?
Peter Gerald Jan Kukielski - President, CEO & Director
Yes, we do in general. I mean also, remember that because of staffing issues related to COVID earlier in the year, we were not able to deploy all the equipment we had. But yes, we are able to deploy more equipment.
Operator
Our next question comes from Greg Barnes of TD Securities.
Greg Barnes - MD & Head of Mining Research
Peter, can you talk a little bit about the underground potential at Constancia Norte. You've done a PEA, what kind of CapEx are we looking at production rates? Any kind of sense we could get there? And would that extend the mine life of Constancia by another several years.
Peter Gerald Jan Kukielski - President, CEO & Director
Yes, I would say thanks for that. I would say that clearly, as we've indicated that the underground would be subsequent to mining out the open pit portion of Constancia Norte. And we still have to complete a PFS. As you said, we've completed a PEA.
Andre, would you like to comment any at all on the additional part of Greg's question?
Andre Taylor Lauzon - Senior VP & COO
Sure. Sure. So Constancia Norte, it's meant to be supplemental feed. The current design with ramp rate from surface so that it could potentially be mined concurrent with mining in the pit. It's probably cheaper to be mined with accesses and portals from the pit. And so there's a number of trade-off scenarios that need to be done on the underground portion at this point in time. And those trade-offs will determine what year. So as you can imagine, your question was around capital cost and the like. And so right now, the base case that we've done is ramp from surface, which is the most expensive option as opposed to very short drifts cutting across from the edge of the pit. But it is in the range, probably $50 million to $75 million-ish in that range for a deposit of that size. But we have a lot more study to do to optimize it at this point.
Greg Barnes - MD & Head of Mining Research
So this -- it would be mined after the pits -- the main pit is mined out or could be another area of the main pit to be mining while you go into the underground area.
Andre Taylor Lauzon - Senior VP & COO
So there's options to do either or -- so if you choose to mine it concurrently, that means you have to start your portals from surface so that they're not affected by expanding the pit. If you go with the cheaper option, then you have to wait until the phase of the pit that's closest to Constancia Norte to reach its final resting its final completed spot before accessing the portals, so they don't lose access. So there's 2 different options. And we just have to look at the life of mine in its entirety. And where is the optimal time to bring it into our production profile.
Greg Barnes - MD & Head of Mining Research
Peter, I just wanted to switch back to Copper World and the environmental groups trying to put some roadblocks in front of you with the votes thing. But are there other avenues that you believe they can take to -- caused you some issues on a couple world? Or is it really very, very difficult given you are on private land? Just trying to get a sense of what roadblocks you could face potentially.
Peter Gerald Jan Kukielski - President, CEO & Director
Greg, my sense is the only roadblocks that we could face others we're facing right now. So the groups who are opposing us or trying to impose roadblocks are the same groups who attempted to do that with Rosemont. And we think that this is pretty well the only avenue that they that -- well, we don't know what they think, obviously. But we think that there are no other avenues that they can pursue. Remember, I mean, this is -- a couple of world is entirely on our private land and private land use in the United States and the State of Arizona is regarded as sacrosanct. So the only avenue that they really have to approach us on is that through this water of the United States Avenue, and as I think all of you know, there was a jurisdictional determination in 2001 by the Army Corps of Engineers stating -- sorry, 2021 stating that there are no waters of the United States in the area of the project, certainly on Rosemont. So yes, we think this is the only avenue. We don't know. We certainly are not aware of any other.
Greg Barnes - MD & Head of Mining Research
Has the army call looked at that on the Copper World ground specifically, Peter?
Peter Gerald Jan Kukielski - President, CEO & Director
Andre, would you like to respond to that?
Andre Taylor Lauzon - Senior VP & COO
Sure, sure. So the Army Corps has looked at the Rosemont footprint per se. And that's where the jurisdictional determination was completed. The Army Corps has looked at our entire site for a number of years, probably for 4 to 6 years. So the Army Corps is very, very familiar with our footprint. The current rule for the waters of the U.S. right now is what they call the [Rapanos] decision. And the Army Corps has ruled on a number of jurisdictional determinations all around us. As close as Quail Creek to Mission mine, even some of the tribes who are suing us. And so all around as the Corps has ruled that there are no jurisdictional waters. And so it gives us great confidence with knowing that not only with the studies that we've done, but the Army Corps, their silence is, in our view, anyways is they're very confident there are no waters as well too.
So they've known that we've been doing these activities now for close to 2 months. And so they're very knowledgeable about the work that we're doing and the washes that the opponents claim to be waters of the U.S., and they haven't done anything. So we're quite confident that they agree with us that there are no waters here under the current rule.
Greg Barnes - MD & Head of Mining Research
Okay. So you don't have a jurisdictional ruling from them on that on your specific world ground not yet.
Andre Taylor Lauzon - Senior VP & COO
There is no requirement for a jurisdictional ruling. -- jurisdictional ruling. All that is, is it's call it, a complementary service that the core does to tell you whether you need a permit or not. And so there is no requirement for that. You just need to know that you're not breaking the law. And we've done exhaustive surveys throughout our property. In addition to we've done a jurisdictional determination on the other side, and with some of the locations. But without that jurisdictional determination, there's been numerous all around us that have been completed on washes that are downstream of us, they're not jurisdictional. So we're very, very confident that aren't any near risk.

Our next question comes from Dalton Baretto of Canaccord.
Dalton Baretto - Analyst
Peter, at the risk of stating the obvious, you guys and us have been surprised by court ruling in Arizona before. But I'm just wondering, what do you guys like the odds are that these groups get the injunctions they're looking for?
Peter Gerald Jan Kukielski - President, CEO & Director
I mean Dalton, thanks for the question. I have no idea what the odds are. I have no idea. It really is a decision that will be made by Judge Soto and I don't know what the odds are. What I do know is that no matter what happens, we will proceed with the completion of the PEA and the feasibility work that we need to do in order to move the project forward regardless of any outcome of what Judge Soto may decide. But we are hopeful that Judge Soto will understand the simplicity of what's in front of him and make the right decision.
Dalton Baretto - Analyst
And so Judge Soto's ruling on this one as well, just to confirm?
Peter Gerald Jan Kukielski - President, CEO & Director
Yes, that's correct.
Dalton Baretto - Analyst
Okay. And then how do you -- the court rulings and the lawsuits decide, how do you think about copper from a broader social license perspective? Is the only opposition you're seeing from the environmental groups. What's the feeling from the local population?
Peter Gerald Jan Kukielski - President, CEO & Director
So I will let Andre answer that in general, though, the opposition that we are receiving is from exactly the same environmental groups who opposed Rosemont. And so there's no surprise there. Beyond that, I think let me ask Andre to respond to the rest of that. I would just add that there is a lot of support locally, but Andre can elaborate on that.
Andre Taylor Lauzon - Senior VP & COO
Yes, agreed. So the reality is, it only takes 1 person to file a lawsuit. And so as Peter mentioned, the group of people that oppose is relatively small compared to the group of people that support the project. In terms of what's changed, though, is this PEA as it comes out really touches on a lot of key aspects that the opponents were complaining about. And the key aspect in this case here, it's a very environmentally well-thought-through plan. We're really excited to share that when it comes out. A key component of that is being able to produce copper in the U.S. -- finished copper and the unique characteristics of the deposit allow us to do that. And we think that a lot of the talking points that our opponents have with regards to their previous view on what the project was we think disappear. And so we're very excited for the PEA when it comes out for people to be able to review it, and they'll see that this is -- will be a world-class copper deposit that meets all stakeholders' needs.
Dalton Baretto - Analyst
Okay. Great. And maybe I can use that to switch gears a little bit. You guys have given us some sense of what Phase 1 looks like in terms of the fact that it's going to be a 15-year mine life. And I understand the PEA is coming out in a couple of weeks. But can you tell us anything else in terms of how big do you think it's going to be? Are you going to be leaching the sulfides as well as the oxide -- and what copper price you're using to determine that it's economically viable?
Peter Gerald Jan Kukielski - President, CEO & Director
Dalton, I think it's a little bit early to sort of provide much of those answers because we haven't completed the PEA work yet. What I can say is that we do anticipate it will be a combination of sulfide and oxide processing, the scale right now is subject to completion of the technical and financial analysis. So I don't really know scale of output, scale of throughput or anything like that right now. What I can really offer definitively, it will be a combination of oxide and sulfide processing.

Okay. And maybe I can squeeze 1 last 1 in. Llaguen in Peru, you're going to have an inferred resource in Q3 of this year. And I understand this project that's reasonably close to infrastructure and so on. Is there a chance that this thing could get accelerated maybe even ahead of Copper World just given some of the local opposition on Copper World?
Peter Gerald Jan Kukielski - President, CEO & Director
No, I don't think so. I mean we completed the first phase of drilling. We're still waiting for some final assays. We'll launch the second campaign, but it is way too early. Because once we complete the drilling campaign, we would have to proceed with a normal permitting regime in Peru. The only difference from -- between this and other areas is there's no indigenous population involved and so there's no requirement for Consulta Previa. But otherwise, it's all the same.
So Llaguen is very, very early stage. We think to your point about Copper World, we actually are very confident that we'll be able to push ahead with Copper World according to the time line that we provided to you previously, which is completion of a PFS this year, completion of a feasibility study next year with potentially sanctioned by the end of next year.

(Operator Instructions) Our next question comes from Stefan Ioannou of Cormark Securities.
Stefan Ioannou - Analyst of Institutional Equity Research
I'm just curious, could you maybe just remind us switching gears to Manitoba, just -- you mentioned you're doing some additional infill drilling on the tailings strategy there at Flin Flon. Can you just remind us sort of maybe the rough time lines to potentially get that into production?
Peter Gerald Jan Kukielski - President, CEO & Director
Look, Stefan, thanks for that. I think it's too early to tell what the time line might be right now. There's quite a lot of work to do that remains to be done. And we need to look at it in the context of the broader camp as well. So there's so much opportunity in Manitoba right now with tailings at Flin Flon. There's also a potential tailings reprocessing at Anderson. There's also a couple of additional phases at Stall. So right now to see how that fits into the suite of our, I guess, high turn -- high-return initiatives ahead of us, it's a little bit early to say. So I would say that we need to complete some work on all of those initiatives in the remainder of the year, and we'll have a much better idea as we progress through the year, how it might look but it is too early to provide any feedback with respect to timing.

Our next question is a follow-up from Orest Wowkodaw of Scotiabank.
Orest Wowkodaw - MD & Senior Equity Research Analyst of Base Metals
I have a follow-up around Copper World and your development plans there. When I think about your balance sheet and your cash flow profile, we've still -- I guess we're still waiting to see that inflection point on your free cash flow generation. Are you going to set some firm, I guess, targets in terms of where you would like to see the net debt get to before you move ahead with sanctioning something like Copper World? Or how should we think about your balance sheet in the context of funding something like Copper World, if you plan to make a sanctioning decision by the end of next year?
Steven James Douglas - Senior VP & CFO
Yes. It's Steve here. I think it's a little premature until such time as we're through the PFS and through the optionality as it relates to what potential financing strategies we can apply because it does to a degree, and then we've talked at length, I won't go over that again. But we've talked at length that depending on the outcome, it may inform some of our financing strategies. It's clearly will form potentially what, if any pursuit we might do as it relates to a partner. So there's a lot of stage gates that we got to go through at this point before we start figuring out how it is we're going to best finance it. Your question on inflection point is a little different in the sense that we talked at length in the press release regarding and a little bit here regarding the just timing in terms of concentrate sales owing to some of the logistics issues we've experienced on our -- primarily in our Manitoba operations.
But what we need to see -- again, I've said this before, I'm not a fan of debt targets, I believe structure matters. So I mean all of those things are going to be put into the great calculus that's going to be how it is we will pursue this. But we remain convinced that we are going to see that inflection point as it relates to positive cash flow generation. We see it just in our working capital today. We know we've got excess inventory sitting there ready to be sold that we're going to generate cash.
So we're still, while back-end loaded this year for a variety of reasons. We're going -- we are going to be generating in our view, significant free cash flow this year, provided prices hang in, which at current levels, we see they will. But I think a lot of that I know it's a long-winded way of saying stay tuned. But I can assure you at such time, we are going to take all of our capital requirements, including looking at the debt maturities that come in 2026 and 2029 before we proceed to sanctioning in it.
Orest Wowkodaw - MD & Senior Equity Research Analyst of Base Metals
Is it -- I realize you haven't released the study yet on Copper World. But should we be anticipating a project CapEx that's somewhat similar to Rosemont in terms of potential CapEx? Or is this something that could be a lot smaller?
Peter Gerald Jan Kukielski - President, CEO & Director
No, Orest, I think you should think in that region somewhere, it's a little bit premature to say so, but I think you should be assuming something in that region.
