[Alan T. C. Hair, President, CEO & Director]

Thanks, Carla. Good morning, everyone. Firstly I wanted to note that a requisition for a meeting of Hudbay's common shareholders has been submitted by a shareholder for the purpose of considering an advisory resolution with respect to certain potential transactions. As per our October 23 press release, Hudbay's board will respond in due course. The purpose of this call is to discuss our quarterly results. So when we get to the Q&A portion of the call, I'd be a happy to take questions on those results.In the third quarter, we executed well against our strategic priorities and delivered strong financial results as we continued to focus on developing and operating our portfolio of high-quality assets in mining-friendly jurisdictions. In particular, at Constancia, we generated record mill throughputs and record copper recoveries for the mine as a result of our continued optimization efforts. In Manitoba, we delivered solid results and believe the optimal processing scenario for the Lalor gold and copper-gold zones is to refurbish the New Britannia gold mill. And at Rosemont, pending the receipt of the Section 404 water permit from the Army Corps of Engineers, we are positioned to finalize the financing plans for the project and move the project into construction.Consistent with our base strategy of optimizing its current operations and evaluating and pursuing complementary growth opportunities, we also announced the transaction to acquire 100% of Mason Resources. This acquisition provides us with ownership of a deposit in a mining-friendly jurisdiction that is similar in scale to Constancia and Rosemont at a cost of $15 million, 1/3 of our 2018 exploration budget. It will be strongly accretive to resources per share at a minimal cost, and it's an excellent example of how our experienced corporate development team is driving value creation today and adding to the company's high-quality pipeline of copper projects to support longer-term value creation for shareholders.Despite weakened metal prices during the quarter, our net profits and earnings per share were $22.8 million and $0.09, respectively. We produced 40,000 tonnes of copper in the third quarter, up from 37,000 tonnes of copper in the second quarter of 2018. Based on results to date, we are on track to meet all of our production and cost guidance expectations, as revised for Manitoba costs last quarter. These solid results continue our track record of driving consistent operations at our mines.We also continue to generate strong free cash flow and reduced net debt in the third quarter. Operating cash flow before change and noncash working capital was $122 million for a total cash flow generation of $557 million in the last 12 months. Since 2016, we have reduced our net debt position by more than $700 million, ending the quarter with a net debt of $516 million.Now let's turn to our South American business unit, our Constancia mine, where we achieved a few significant operational milestones. We delivered a very strong quarter of mine and mill throughput, posting new records in both quarterly mill throughputs and copper recoveries. While recoveries will vary from quarter to quarter depending on the complexity of the ore feed, we are seeing good results from the recovery improvement initiatives that we are implementing and we are on track to deliver the recoveries anticipated in the technical report issued earlier this year. We also realized good copperhead grades from Constancia in the third quarter. This was a result of changes in the sequence of the mine plan, including stockpile movements, in an effort to maximize recoveries. It should be noted we have a scheduled semiannual 5-day maintenance turnaround in Constancia later this month.To put these improvements in perspective, when we commissioned Constancia, we delivered industry-best performance in the initial ramp-up. Having completed initial the ramp-up, our priority was optimizing ore throughput. Based on enhanced plant availability, we have achieved that objective, and ore throughputs is consistently running at or above design rates. We next turned our focus to improving copper recoveries. We have made significant progress on this in the third quarter and are continuing to work in improvement initiatives. A side benefit of our work in copper recoveries has been a better understanding of how to optimize our molybdenum processing plant, which we are now running much more frequently and with better overall results. We are continuing to pursue these improvement initiatives in the fourth quarter.As anticipated, Constancia unit costs also declined in the third quarter compared to the first half of 2018, which included a signing bonus associated with the 3-year collective bargaining agreement as well as costs associated with a major maintenance turnaround. For context, based on Wood Mackenzie data, Constancia is the lowest cost sulfide open-pit mine in South America. I'm very proud of our performance at Constancia, and I want to recognize the outstanding efforts of our team there.Based on our successful development of Constancia and track record of building social license to operate, we are recognized in Peru as a leader in community relations, and our track record compares very favorably to other nearby mining operations. Since acquiring Constancia, we have entered into over 90 agreements with different communities and local governments and see multiple elections and changes of local administrations without significant interruptions.Turning to our Pampacancha deposits, our discussions with the local community to acquire the surface rights are progressing. We are continuing to be patient to ensure that any agreements supports our longer-term exploration plans for Constancia, and we continue to expect to be able to reach an agreement in time to begin mining at Pampacancha in 2019. As a testament to the massively consistent approach we're taking with community relations, we recently entered into an agreement with 1 of the 4 local communities for exploration access to some of the highly prospective properties within trucking distance of Constancia that we acquired earlier this year.In summary, between operational optimization and the development of Pampacancha nearby exploration targets, we are making excellent progress in growing the long-term value of our copper success story. Turning to Manitoba. At Lalor, ore mined decreased by 18% in the third quarter compared to the same period last year. Lower production tonnage was primarily attributed to the exhaust fan failure in June that constrained ventilation and production from areas of the mine until mid-August. The mine has also been affected by a shortage of skilled workers, and a fall of ground in August delayed the timing of the production stope. The fall of ground was limited in impact and is not expected to have any long-time effect on production or reserves and resources.We have identified the root causes of our setbacks in 2018 and have taken steps to address them and ensure Lalor's position for long-term success. Specifically, we have strengthened the on-site team, changed our operating practices and have addressed the resourcing constraints. The new Lalor paste plant was commissioned during the quarter with backfill voids being managed within normal thresholds. We now expect the Lalor production ramp-up to 4,500 tonnes per day to occur in the first quarter of 2019.Hudbay has a long history in Manitoba, and we have discovered mines and reclaimed numerous mines in the province. Our Reed mine ceased production as planned in the third quarter, and all of the Reed ore is now being milled. Closure activities were completed ahead of schedule and under budget, with reclamation continuing in 2019. We're very proud of Reed, an excellent example of our commitment to responsible and safe mining. Located entirely within a provisional park, Hudbay's track record at all stages of the mining cycle facility, timely receipt of permits and, during the mine's construction, there were 0 lost time accidents. Reed was designed from the start to avoid impact in the surrounding environment and foreclosure and reclamation to return the site to its original condition. I'd now like to provide an update on the work we've done over the last several months on the Lalor gold and copper-gold zones. We've completed our trade-off studies and believe that the optimal processing scenario is to refurbish the New Britannia gold mill with significant upside potential from nearby satellite deposits. I'll refer you to Slide 13 of our presentation. The northern portion of Lens 25 was a key area of focus of infill drilling and test mining this year. In addition, we have undertaken the full review of all the resource models that were supporting our previous resource and reserve estimates, starting with the copper and gold-rich Lens 27. We are encouraged by the very positive results that have come out of this work to date and expect an increase in the tonnage of high-grade copper and gold resources. In parallel, we have continued to progress the baseline studies required for the permanent modifications of the New Britannia mill as well as a regional gold exploration program. These efforts were conducted in support of trade-off studies to assess the optimal mining and processing options for the gold mineralization at Lalor. This work supports the conclusion that the refurbishment of the New Britannia mill, including the addition of a copper flotation circuit, is the preferred option for maximizing the value of the gold-rich resources from Lalor. This substantially increased gold production will provide enhanced optionality to Lalor. Refurbishing New Britannia will pave the way for the creation of substantial upside both from the additional resources and exploration potential of the Lalor mine and its nearby satellite deposits and also from our gold exploration potential in the Snow Lake belt. We expect to provide more details on an updated mineral reserve and resource estimate for Lalor and other details in the first quarter of 2019, once we've advanced the engineering and mine planning work.The upside potential for mineralization amenable to processing at the New Britannia mill extends from Lalor to the old Chisel mine, where we have several historical occurrences of copper and gold mineralization beneath the existing ramp. These copper-gold-rich zones, which represent classic pathways to VMS deposits, will be drill tested over the next 3 months. This summer, our exploration team already intersected 5.2 meters at 2.7% copper and 1.2 grams per tonne gold in hole CH1807 at a depth of 1,200 meters. This intersection sits in the edge of a large burr hole EM plate modeled from 3 holes, some 600 meters away from the center of conductivity, where we expect to find higher-grade mineralization.In addition, Hudbay controls a very large land package prospective for gold mineralization in the Snow Lake region. Geochemical sampling and geophysical surveys conducted in high-priority areas during the second half of this year will be used to define drill targets to be tested during the winter in the immediate vicinity of the historical New Britannia mine. The upside potential from known mineral resources of nearby satellite deposits includes historical estimates of mineral resources at Hudbay's New Britannia and Squall Lake deposits as well as the recently acquired WIM deposit. We are pursuing a strategy of optimizing the value of our gold resources in Manitoba through the refurbishment of New Britannia. This approach balances our near-term focus on maximizing zinc production and advancing the restart of New Britannia with a compelling medium-term plan to capitalize the existing infrastructure and significantly grow gold production from wholly owned deposits that are unencumbered by any royalties or streams. I'll now turn to our Arizona business unit. We're very pleased to have in our pipeline a high-quality development project with well-established infrastructure in Arizona. We are well positioned to move the Rosemont project into construction soon after permitting is complete. It is important to note that since our acquisition of Rosemont, we have secured 6 new permits for the project, including the final record of decision from the U.S. Forest Service, and successfully defended 5 lawsuits related to Rosemont permits. The next milestone is obtaining the Section 404 water permit from the Army Corps of Engineers. While the permitting process for Rosemont has been lengthy, we respect the diligence exercised by the permitting agencies in ensuring that their processes are robust. We are confident that we will receive the remaining required approval based on our permitting track record to date. Once we receive the final permit, we'll finalize our financing and construction plans for the project. As noted in previous disclosure, spending in the first year of Rosemont's 3-year construction period is expected to be less than $150 million, a substantial portion of which is scheduled to be sourced from our existing funding partners. As we consider our financing plans for Rosemont, we're working within a disciplined framework that we developed in 2017, which was carefully considered and approved by our Board of Directors. It sets clear criteria on financial risk tolerance and our disciplined approach to financing our pursuit of long-term growth and value creative initiatives. Unlike many of our peers, we were not required to issue discounted equity, sell assets or hedge, cycle ore metal prices in 2016, and our framework is intended to ensure that we can continue to grow our business prudently.In the same way that we're disciplined in our approach to acquiring Constancia and Rosemont, we are disciplined and conservative when considering any potential acquisition. We have a long-held belief that the most significant opportunities for value creation are through exploration and mine development. We have unique strengths in these areas together with our strengths in community relations, and we prioritize opportunities that enable us to apply those capabilities. We also screen acquisition opportunities against a number of long-standing, stringent criteria. We target copper deposits in select mining-friendly jurisdictions in the Americas with the potential to be long-life, low-cost operations once developed. Potential opportunities should involve a meaningful operating role for Hudbay and be accretive on a per share basis, primarily not per share and reserves and resource per share. We look at opportunities at all stages of development from early-stage exploration to producing assets. Hudbay's reviewed over 100 assets and participated in over 30 processes over the past 5 years have been outbid for assets a number of times due to our strict focus on accretion and value. The only material acquisition we have made, Constancia and Rosemont, have substantially enhanced our portfolio of assets particularly as we have brought up expertise in mine development to them.An excellent example of our acquisition strategy in action is the agreement we announced yesterday to acquire 100% of Mason Resources and the Ann Mason project. Ann Mason is a large copper porphyry deposit located in the Yerington copper district in Nevada. Hudbay has been a shareholder of Mason Resources since 2017, and we have followed the project closely for several years. The project has a large existing resource with 1.4 billion tonnes grading 0.32% copper in the measured and indicated category, plus 600 million tonnes grading 0.29% copper in the inferred category. The deposit also contains by-product gold, silver and molybdenum. The Ann Mason deposit is similar in scale to Constancia and Rosemont. We view Ann Mason as an advanced exploration property and it will be a priority exploration initiative. The deposit remains open in several directions. There are high-grade skarn targets in the property and several untested IP anomalies. Further, the U.S. Army Corps has confirmed that no 404 water permit will be required at Ann Mason. The Ann Mason acquisition meets our stringent growth criteria and builds on our successful acquisitions of Constancia and Rosemont. It is a high-quality asset that provides a deposit of significant scale as one of the largest undeveloped copper porphyries in North America and substantially increases Hudbay's measured and indicated and inferred resources. The transaction is highly accretive on a resource per share basis, and we are paying approximately $0.002 per pound of measured and indicated copper in the ground. Ann Mason has the potential to be a long-life, low-cost mine in one of the world's best jurisdictions for mining and adds a significant asset to our pipeline for development after Rosemont. It is at the stage where we can leverage our management expertise in exploration, engineering, permitting and construction to maximize the project's ultimate value for our shareholders. We are constantly evaluating new opportunities in screening for high-quality assets that fits our growth criteria, but I want to highlight the lack of actionable opportunities in the copper space. During the last cycle, there were almost no new significant discoveries and many of the projects on Slide 23 have been known for decades. This, in part, is setting the stage for the pending supply gap in copper, and we are pleased to be adding Ann Mason to our pipeline as a long-term development option. Ann Mason is the third largest resource held by a junior company in our operating jurisdictions in Canada, United States, Peru and Chile. The Ann Mason acquisition delivers a deposit that is similar in scale to Constancia and Rosemont for a net acquisition cost of approximately $15 million or 1/3 of the 2018 exploration budget. The Mason Resources team has done an excellent job of progressing the deposits where it is today. We look forward to advancing Ann Mason within Hudbay and adding value through exploration, which we view as one of our key differentiators, as evidenced by our track record of increasing reserves at each Constancia, 777 and Lalor, which substantially increase the returns of our initial mine capital investments. With a strong foundation in Constancia and Lalor, near-term development opportunities in Rosemont and Pampacancha, the potential to substantially increase gold production and optionality at Lalor and the addition of Ann Mason to our earlier stage development pipeline, we believe we've made excellent progress in utilizing both exploration and M&A to build out a robust growth pipeline. In conclusion, we're pleased with our operating results and financial performance as we continue to generate strong cash flow from unhedged copper and zinc production. Our portfolio of long-life, low-cost assets in mining-friendly jurisdictions in the Americas provides relative scale to investors with a meaningful growth profile. We are proud of our proven drill-and-build value creation strategy and have the management experience and skill to deliver on our strategic plans and continue to grow long-term shareholder value.Before I turn it over to Q&A, as I mentioned, we'd be pleased to take your questions on the quarter.

[Operator]

[Operator Instructions] And we will hear first from Orest Wowkodaw.

[Orest Wowkodaw, Senior Equity Research Analyst of Base Metals]

I wanted to get a little bit more color on the operational performance improvement at Constancia and specifically the -- both the grade and the recovery. Maybe we could start with the recovery 85%, I mean, that's a big step-up from what we've seen historically. How sustainable do you think that is moving forward? And do you think that's going to be volatile? Or could we -- is that going to be jumping around a fair amount as we move into the next couple of quarters?

[Alan T. C. Hair, President, CEO & Director]

Orest, I think it's fair to say that the recovery will be variable depending on the particular ore types we're treating. So I think you can see some variation from quarter to quarter. What we are confident with though is that -- I mean, for example, for this year, we're heading towards the basic recovery in the technical report, and I think we're confident of those sort of recovery numbers going forward. But there will certainly be quarter-to-quarter variation depending on ore type, zinc content and things that affects -- can affect recoveries.

[Orest Wowkodaw, Senior Equity Research Analyst of Base Metals]

So was there something special about the Q3 ore mix that drove the recoveries that high?

[Alan T. C. Hair, President, CEO & Director]

Certainly, I think there might have been more hypogene in Q3, but there are other factors that come into play. We are getting a better handle on managing blending from a recovery perspective. So there's maybe more movement to and from stockpile, but we're also implementing a number of metallurgical improvement initiatives. So as I say, we're confident on achieving and perhaps even exceeding ultimately the recovery stage in the technical report.

[Orest Wowkodaw, Senior Equity Research Analyst of Base Metals]

Okay. And then how about the grade? I mean, we saw unexpected pickup in copper grade, whereas your guidance on the tech report was indicating a continued decline. Is that just a one-off here in Q3? And should we anticipate that grade to fall close to back around the 0.40% mark moving forward? Or you could just -- is there some changes going on in the mine plan?

[Alan T. C. Hair, President, CEO & Director]

There's obviously short-term optimization of the mine plan. I mean, I think you'll see the grades maybe dropped back slightly in Q4, but I think overall, we would expect 2018 to be slightly higher than the technical report number. We'll obviously provide 2019 guidance earlier in the new year.

[Operator]

And our next question comes from Lawson Winder.

[Lawson Winder, Associate]

Am I live?

[Alan T. C. Hair, President, CEO & Director]

Yes, you are.

[Lawson Winder, Associate]

Okay, great. So just sticking with Constancia, I just wanted to inquire about the Pampacancha surface rates negotiations, so maybe just from a couple of points of view. So in terms of last quarter where you noted that the negotiations were -- you were also pleased then and they were more economic in nature, maybe just update us on what's happened since the last call to today in terms of whether you've -- what sort of boxes you've checked that leads you to conclude that you're still pleased. And then also maybe just help us think of this in terms of how many parties are still involved. So who's left to sort of get on board before you can wrap this up?

[Alan T. C. Hair, President, CEO & Director]

Okay. Well, I'll just point to the fact that -- I think I mentioned that we've negotiated a large number of these agreements in our time in Peru. We're rapidly approaching 8 years in the county now and have been successful in achieving the desired end result in all our various community negotiations. And we don't see negotiations with Pampacancha to be any different. Things are slowed down slightly right now because we've just gone through a period of municipal elections last month and community elections this month, but we remain confident given the status of the dialogue to date that we will get an agreement in place. As I mentioned in the script, we're also looking at the bigger picture. We've consolidated the land positions to the northwest of Constancia, what we believe is a very prospective area. In fact, we coveted that ground even before we acquired Constancia, and we're finally able to get over the line earlier this year. And that will involve negotiations with another 4 different communities from the 1 we're talking to around Pampacancha. We've actually already been successful to get exploration access on one of the Kusiorcco targets. But I mean, we look at our overall community relations in the broader picture, and we're very mindful of what we do for one community would be potentially replicated for others.

[Operator]

And our next question comes from Greg Barnes.

[Greg Barnes, Managing Director and Head of Mining Research]

Alan, I'm not going to ask you questions strictly related to the quarter, but with Rosemont -- and I appreciate it is your top priority and you are not going to do anything to jeopardize funding it. How long though can you keep it in that position? If the permitting process continues to take longer, say another 12 months, and you still don't have a 404, will your attention start to shift elsewhere?

[Alan T. C. Hair, President, CEO & Director]

Certainly, the permitting process has maybe taken longer than we originally anticipated. We are confident that, that process is coming close to a conclusion. So I don't think that we'll be in the scenario that you outlined, Greg.

[Greg Barnes, Managing Director and Head of Mining Research]

Okay. Just wanted to shift to Lalor. Particularly on the mining, when do you think you can start to mine the gold zone on a consistent basis? And at what rate and what mining methods will you be thinking about there?

[Alan T. C. Hair, President, CEO & Director]

As I indicated in the script, Greg, I think we're looking to provide more detail on that in Q1. We've now got the direction like -- established. We're now moving on to the next phase to nail down some of those particulars.

[Operator]

And moving on, we have a question from Oscar Cabrera.

[Oscar M. Cabrera, Research Analyst]

Alan, if we just get back to Constancia, I believe in your remarks, you said that you expected resolution on the Pampacancha land right on the first quarter. When do you think you can start mining ore from the deposit there?

[Alan T. C. Hair, President, CEO & Director]

Just to be clear, Oscar, I said we'd expect to get the agreement placed in 2019. If -- there's a certain amount of lead time obviously, but if we get an agreement by, say, Q2, we should be mining by Q4 or -- that's the sort of time line.

[Oscar M. Cabrera, Research Analyst]

Okay. And so if -- assuming that that's the case, you start effectively mining in 2020, how should we think -- or are there any stripping or anything else you have to do in the main pit? So how should we think about the combined unit operating cost? We had guidance of $7.50 to $9.20 this year per tonne. Would the cost -- they run the same? Or would it increase?

[Alan T. C. Hair, President, CEO & Director]

Well, I think we'll get a specific cost guidance going forward, as we normally do. I mean, the technical report plays out both the material being mined from Constancia around -- from Pampacancha. So I think you can factor based off of those numbers.

[Oscar M. Cabrera, Research Analyst]

Because I think we had talked about a reduction on your precious metals production, which is on a net by-product credit that affects the cost, but just I'm more curious in terms of -- do you have to do anything in particular to the other pit so that you can just maintain cost -- or mining cost around where it is?

[Alan T. C. Hair, President, CEO & Director]

I think with a short-term mine plan, we're always optimizing our operational performance depending on exactly where we are within the plan and a reference to fact that we're now getting more experience in terms of our ability to blend the material better. So I think on a very broad basis though, just factor off the technical report numbers is all I can really suggest.

[Oscar M. Cabrera, Research Analyst]

Okay, that's helpful. And then if I may on the -- on Manitoba, just -- I understand you're giving those numbers on the first quarter, but could you remind me more or less of the scope of the project? I believe we had talked about $100 million in CapEx and not a very long time to get production ramped up. And in addition to that, I'm assuming that you will remain processing zinc, as you are now. So should we expect the combined mine and mill unit operating cost to remain similar to what 2018 guidance was?

[Alan T. C. Hair, President, CEO & Director]

I think, Oscar, really, you'll have to wait until next year, as I mentioned, before we can give a little bit more detail on those projects.

[Oscar M. Cabrera, Research Analyst]

Okay. Well -- and then lastly, please, if I may. Your comment on skilled labor in Manitoba, is this something to be concerned with? Well, do you think that can put inflationary pressure to attract more people going forward?

[Alan T. C. Hair, President, CEO & Director]

It was a problem. I think we're confident that we've addressed it now. It applies both to managerial and technical skills as well as actual miners. We've had to adopt a more fly-in, fly-out approach to staff Lalor from a senior management and technical position, and we're currently employing more contract miners at Lalor. So yes, there has been some additional cost associated with that, but those are included in our guidance numbers. Those steps have been taken, Oscar, just to be clear. So we think that we've addressed those concerns that maybe led to the slight drop in performance in the middle of the year.

[Operator]

And we'll hear next from Stefan Ioannou.

[Stefan Ioannou, Analyst of Institutional Equity Research]

Just, I guess, still in Manitoba, was there any trucking of ore from Lalor over to the Flin Flon concentrator during Q3? Has that kind of ramped up now?

[Alan T. C. Hair, President, CEO & Director]

No. There was -- I mean, it all depends on the Lalor mine outputs. Obviously, the -- as we said, the ramp-up's been delayed slightly, and we do invest in trucking ore again and going forward.

[Stefan Ioannou, Analyst of Institutional Equity Research]

Okay, okay. And I guess just looking forward now, obviously -- so 777 had a relatively decent winding down in the grand scheme of things. What is sort of the outlook for Flin Flon concentrator as we get out to sort of that 2021 time frame?

[Alan T. C. Hair, President, CEO & Director]

Well, in terms of outlook, I mean, our expectation is that when 777 closes, which should be by the end of 2021, our current plan will be to put the Flin Flon processing assets, the concentrator and tailings facility on care and maintenance to maintain the optionality either for additional ore discovery on our part or the part of others. I mean, it's a very valuable asset and the Manitoba government is obviously happy that we do that well. We continue to operate within Manitoba. A good example is the New Britannia mill. I mean, we acquired that back in 2015, and it's been mothballed since 2005. So those are assets you don't want to lose.

[Stefan Ioannou, Analyst of Institutional Equity Research]

Got it, got it, very good. And then I'm not sure if you can comment, but obviously, interesting to see the Ann Mason acquisition. It makes sense from a long-term point of view and some optionality. I'm not sure if you can comment, but obviously, Mantos Copper did have an interest in Mason. With regard to sort of rumors regarding potential acquisitions in Chile, could it have been that there was some sort of confusion with regards to -- whether that Mantos Copper involvement related to assets in Chile versus something in Nevada?

[Alan T. C. Hair, President, CEO & Director]

All I can really say, Stefan, is that we have maintained the position that we don't comment on speculation. And so I just -- I'm not going to provide any comment on your question.

[Operator]

And our next question comes from Mark Llanes.

[Mark Llanes, Analyst]

Just to go back on Constancia. Recoveries increased to 85% from 79% in Q2. [ I know you ] mentioned [ your mine to it ]. Are you reimplementing improvement such as the [ peripheral magnet ] that Jamieson sells, et cetera. Is that -- are you still trying to pursue those? And how much more of an uptick in recovery can we expect if there is any in the next couple of quarters?

[Alan T. C. Hair, President, CEO & Director]

Well, some of the steps we've taken might see some results in the next couple of quarters like with the [ peripheral ] installation, for example. But some of those other things are longer term. But I mean, all I can point to is we should come in around the predicted recoveries within the technical report for this year. So I mean, there is quarter-to-quarter variation and we -- that's just the reality of this business or the -- you're going to see that both in Constancia and Manitoba. But we're confident that we should be able to meet the technical report recoveries and potentially improve upon them with some of the additional work that we're doing. It's too early to make any predictions at this stage. And I would emphasize there will be quarter-to-quarter variations. So I wouldn't necessarily expect the recoveries to be as high in this quarter as they were last quarter.

[Mark Llanes, Analyst]

Okay. And just a follow-up question on the Mason acquisition. You guided -- your team guided to $50 million in exploration guidance at the beginning of the year. Does the acquisition included in that $50 million? Or is that separate?

[Alan T. C. Hair, President, CEO & Director]

It's separate, but we haven't necessarily allocated all our exploration dollars this year. So some of it will be covered off by that exploration budget.

[Operator]

And we'll hear next from Nick Jarmoszuk.

[Nicholas Jarmoszuk, Analyst]

Nick Jarmoszuk from Stifel. On Slide 19, I was hoping you could discuss the $1.1 billion of capital that is required from Rosemont, how you guys are thinking about funding the -- funding that and then whether there is a maximum amount of debt that you guys are comfortable with having on the balance sheet.

[Alan T. C. Hair, President, CEO & Director]

I think we've been fairly clear that when it comes to fund the exact structure of -- the exact capital structure when it comes to fund Rosemont would depend on the timing and the market conditions at the time. Obviously, we've seen even in decent months quite a significant swing in copper prices. So it was high as $3.30 back in June, which was obviously a far better -- would have been a good environment to hedge. They've obviously pulled back a bit again. But depending on the timing of Rosemont on a higher copper price environment, we've spoken with the potential of hedging some of our current production to lock in operating cash flows. We take a look on what the debt market was at that time, what other capital requirements within the business were. So I just think that we're happy that we get lots of tools in our toolbox to finance Rosemont depending on circumstances. So that's all I can really say at this point.

[Nicholas Jarmoszuk, Analyst]

And is there a maximum debt balance that you're comfortable with?

[Alan T. C. Hair, President, CEO & Director]

We do have a sort of -- when we do have financial planning, we do stress test of potential low metal price environments and we get certain parameters with which we want to remain within. As I said in the script, I mean, we have been disciplined and I think we've acquired even more discipline since 2016. But even in 2016, as I pointed out, we didn't issue distressed equity. We didn't have to take out on additional debt. We didn't have to hedge. We didn't have to stream, and we didn't have to sell assets. And we were one of the few companies who has faced it that didn't have to take any of those actions and that's -- that will be our plan going forward. It's to keep the balance sheet protected enough that we don't have to make any of those value-destructive -- take any of those value-destructive actions.

[Nicholas Jarmoszuk, Analyst]

Okay. And then depending on the time line of Rosemont and Ann Mason, do you ever envision a scenario where those 2 major projects could be developed concurrently? Or do you envision doing them consecutively?

[Alan T. C. Hair, President, CEO & Director]

No. I mean, we look at Ann Mason as an advanced exploration project at this stage. I mean, we want to get boots in the ground there, do additional exploration, potentially see if we can bring some high-grade deposits to bear, which would improve economics. Otherwise, it's going to have to see a longer-term -- a higher, longer-term copper price to send it into production. The advantages of acquiring at this stage is that we haven't inherited any real baggage. It gives us a chance to define the deposit correctly from a geometallurgical perspective. It allows us to design the throughput rate that we would consider optimum, and it doesn't commit us to -- we can go down the permitting route appropriately and not be committed to anything suboptimal, which you sometimes get when you take over a project that's further advanced. So I'd say Ann Mason is like -- in our mind, is something that happens after Rosemont's up and running.

[Operator Instructions] We'll hear next from Brian Lalli.

[Brian J Lalli, Director & Senior Analyst]

I guess most of my questions have been answered. And I apologize if I missed this. Just operationally, it looks like on a copper basis, you're trending kind of above, even the high end of your current guidance. Is there anything notable in 4Q that we should think about in terms of maybe getting just to the high end of the guidance relative to your performance for the first 9 months?

[Alan T. C. Hair, President, CEO & Director]

I think I've already mentioned that we expect the head grade maybe to -- we certainly don't expect the same level as we saw in Q3 and as with Q2, the rest of maintenance shutdown taking place this month. It might not be quite as large as the Q2 shutdown, but we will be down for a number of days.

[Brian J Lalli, Director & Senior Analyst]

Got it, okay. That's helpful. And then maybe just following up on the previous question around the balance sheet. I guess, in the absence of a permitting decision, is the plan to still just continue to build a cash balance and, at some point, when you do make that financing decision, maybe you just have a bigger amount of cash that you can sort of deploy proactively towards that future $1.9 billion?

[Alan T. C. Hair, President, CEO & Director]

That's correct. And our share is the $1.1 billion currently. But yes, we believe that Rosemont's close enough in the horizon that that's the most prudent use of the cash in hand.

And with no other questions in the queue, I'd now like to turn the conference back to Carla Nawrocki for any additional or closing remarks.
