Thanks very much, Candice. Good morning, everyone, and thank you for joining us. 2022 was a year of dedication, discipline, and delivery for Hudbay as we completed our first full year of New Britannia and Pampacancha operations, transitioned our Manitoba operation with a new focus on Snow Lake, managed through political uncertainty and logistical constraints in Peru, and committed to further improving our already low carbon footprint.
We were faced with a period of higher input prices and volatile copper prices, but we took measures to reduce our discretionary spending as part of our commitment to disciplined capital allocation and generating free cash flows. More than ever, we are focused on maintaining a strong safety culture in our workplace and continued alignment with our local communities.
In this presentation today, I'll go into more detail about our achievements and challenges in 2022, touch on the operating and financial performance of the business, and provide an overview of our production and cost outlook as we execute on our key strategic objectives for 2023.
Starting on slide three, we're proud to have achieved our 2022 consolidated production guidance for all metals and consolidated cash cost and sustaining cash cost guidance in a difficult environment. This was due to the strong ramp-up of the New Britannia Mill, which successfully increased annual Snow Lake gold production by 46% in its first full year of operations. Similarly, in Peru, a full year of production at Pampacancha helped to bring copper and gold production each by approximately 15% year-over-year.
In Manitoba, 2022 has been a transition year as we closed our 777 Mine and Flin Flon Metallurgical complex after decades of steady operations. The Manitoba team continued to focus on integrating the Flin Flon employees and equipment into the Snow Lake operations in order to significantly reduce our reliance on higher-cost contractors.
We also completed confirmatory exploration drilling at our Flin Flon tailing facility in 2022, which indicated higher grades than reported from our historical mill records. This facility holds in excess of 100 million tons of tailings that have been deposited over the span of 90 years. We plan to complete metallurgical test work on the Flin Flon tails to assess the metallurgical recoveries. Our Anderson tailings facility in Snow Lake contains significant amounts of gold deposited over many decades.
Given our enhanced gold processing capacity in Snow Lake, we are in the early stages of evaluating a similar opportunity to reprocess the Anderson tailings as well. Elsewhere in Snow Lake, the Lalor expansion beyond 4,650 tons per day is ongoing, and the Stall recovery improvement program is well advanced and on track for completion in early 2023. We also repaid 50% of the gold prepay facility that helped fund our New Britannia Mill refurbishment.
In Peru, we announced the signing of an exploration agreement with the Uchucarcco community in August, providing access to the Maria Reyna and Caballito satellite properties located within trucking distance of Constancia, I'll touch on these opportunities shortly.
In early 2022, we completed an internal positive scoping study at Constancia Norte, highlighting an inferred mineral resource estimate of 6.5 million tons at 1.2% copper. The study concluded that the two high-grade skarn lenses could be mined by underground methods starting in 2029 to supplement the open pit production.
Later in the year, our team also completed an initial mineral resource estimate for Llaguen and identified a higher grade core. Llaguen is a 100% owned copper molybdenum porphyry deposit located in the La Libertad region in northwestern Peru, near the city of Trujillo and within close proximity to existing infrastructure, water, and power supply. More importantly, in Peru, we're extremely proud of the team's efforts in maintaining strong operations throughout the year, despite operating in a challenging environment with heightened inflation, recent political changes, and logistical challenges.
The team has been able to successfully navigate this environment while maintaining steady operations and achieving our copper production guidance in 2022. In the United States, we demonstrated the value at our Copper World project with the release of the preliminary economic assessment in June. The PEA outlined a two-phase mine plan incorporating the newly discovered deposits along the east deposit, formerly known as Rosemont.
Phase one reflects a 16-year standalone operation on private land with average annual copper production of approximately 86,000 tons at attractive cash costs of $1.15 per pound. Phase one generates robust economics with an after-tax net present value of $741 million at a 10% discount rate and an internal rate of return of 17% using a copper price of $3.50.
Phase two at Copper World expands mining activities onto federal land and extends the mine life to 44 years with average annual copper production of approximately 100,000 tons. The projected after-tax NPV of the second phase at the time of sanction would be $2.8 billion, which demonstrates the significant upside opportunity this second phase brings to the project.
After the completion of our PEA for Copper World, we initiated the state-level permitting process and received the first of the state permits, the Mined Land Reclamation Plan, in 2022. We completed the technical work to support the pre-feasibility study for Copper World, which I'll touch on in more detail later in the presentation.
In late 2022, as part of our disciplined financial planning, we announced three specific prerequisites, including specific financial leverage targets that would need to be achieved prior to making an investment decision in Copper World. Finally, we have been rationalizing our non-core asset portfolio and divested our 100% interest in the Lordsburg property in New Mexico, which was acquired through the Mason acquisition in 2018. We completed the sale of our equity interest in Fireweed Metals, which we received in 2018 in exchange for the sale of our Tom and Jason properties in the Yukon.
Turning to slide four, we started to see the benefits from our recent brownfield investments through increased production and cash flows in our 2022 results. Q4 consolidated copper production increased by 20% from the Q3 , primarily due to higher copper grades in Peru. Consolidated gold production was slightly higher than the Q3 due to higher gold grades in Peru, which were partially offset by lower Lalor gold grades in Manitoba.
As I mentioned, we achieved full year consolidated production guidance for all metals. Annual copper and gold production was on the lower end of the guidance range, primarily due to lower-than-planned grades in the Q4 in Peru as we implemented short-term mine plan changes to mitigate the risks associated with logistical and supply chain disruptions.
Consolidated copper cash costs increased from the Q3 levels as a result of lower precious metal sales volumes and continued inflationary cost pressures, partially offset by higher copper production. Sustaining cash costs also increased from the Q3 due to the same reasons affecting cash costs and higher capitalized exploration, slightly offset by lower sustaining capital expenditures.
Operating cash flow before changes in non-cash working capital was at $109 million during the Q4, reflecting an increase of $27 million compared to the Q3. Q4 adjusted EBITDA was $125 million compared to $99 million in the Q3. Results were higher than the prior quarter due to higher copper sales volumes and higher copper, gold, and molybdenum prices, but partially offset by the temporary buildup of unsold inventory in Peru.
In light of the environment in the second half of 2022, with increasing input prices and declining copper prices, we delivered $30 million in discretionary cost reductions across the business through lower growth, capital, and exploration expenditures. We exited the year with $226 million in cash and equivalents, as well as undrawn availability of nearly $350 million under our revolving credit facilities. On slide five, we summarize our Peru operating results.
During the quarter, we produced 27,000 tons of copper and 21,000 ounces of gold at 21% and 64% increase, respectively, over the Q3. These production increases were due to higher grades and recoveries. The Q4 was a record quarter for gold production in Peru. Full year copper production increased by 15% year-over-year to 89,000 tons, achieving the annual guidance. Full year gold production increased by 16% year-over-year to over 58,000 ounces, fell short of 2022 guidance.
This was due to a short-term change in the mine plan, where we prioritized the processing of lower grade stockpiles and shorter haulage distances of ore from Constancia pit. This allowed us to reduce our fuel consumption and keep the mill at steady production during a period of nationwide social unrest and road blockades following a change in Peru's political leadership in early December.
Despite these changes, total ore mined during the Q4 increased by 7% and total ore mined was slightly higher than the previous quarter. Unit operating costs in the Q4 were 4% higher than the Q3, primarily due to higher mining costs and continued inflationary pressures. Full year unit costs were 19% higher than 2021 due to a higher strip ratio, higher mining costs, and inflationary pressures on fuel, consumables, and energy costs, partially offset by higher ore milled.
Peru's cash costs in the Q4 declined by 20% to $1.34 per pound compared to the Q3 due to higher copper production and higher byproduct credits resulting from higher grades. Sustaining cash costs decreased by 15% quarter-over-quarter, primarily due to the same factors affecting cash costs and lower sustaining capital expenditures, partially offset by higher capitalized exploration.
While we were successful in completing two port shipments in December, inventory of approximately 25,000 wet metric tons of copper concentrate was unsold at the end of the quarter due to nationwide blockades. Given that, we have been able to continuously operate. Our concentrate inventories at site reached a peak of approximately 47,000 tons in mid-February. We were able to complete three concentrate port shipments in January, and regular transportation of concentrate has resumed since mid-February.
We expect to return to normal concentrate inventory levels in the next several months. As an additional prudent measure intended to ensure positive cash flow generation and continued financial discipline, we expect to extend our existing quotational period hedging program to cover approximately 13,000 tons of contained copper in the unsold concentrate inventory to lock in current copper prices.
Moving to the next slide on Manitoba. Gold, zinc, and silver production declined during the Q4 compared to last quarter, primarily as a result of lower grades at Lalor in line with the mine plan. Copper production was slightly higher than last quarter. Full year 2022 production in Manitoba was impacted by the planned closure of 777 in June, resulting in a decrease in copper, zinc, and silver production, while annual gold production increased by 13% as New Britannia ramped up to full production.
Full year production of all metals in Manitoba achieved the 2022 annual guidance ranges. Ore mined at Lalor increased by 6% in the Q4 compared to the Q3, mainly due to the higher production initiatives and the integration of the Flin Flon employees and equipment, partially offset by a planned maintenance program at the mine.
We continue to advance several key initiatives to support higher production levels at Lalor, including building long-haul inventory, improving stope back fragmentation, optimizing the development drift size, and focusing on shaft availability improvements to enable more ore to be hoisted to surface while reducing inefficient trucking of ore via the ramp. The combined Snow Lake mills processed 5% less ore in the Q4 due to the employee transition and planned maintenance.
The New Britannia Mill continued to achieve consistent production, averaging 1,530 tons per day in the Q4. Combined unit operating costs in the Q4 were relatively in line with the Q3. Full year combined unit operating costs increased by 27% compared to 2021, reflecting the stand-alone higher cost structure of Snow Lake after the closure of the 777 Mine and the Flin Flon operations in mid-2022.
Manitoba's gold cash costs were $922 per ounce in the Q4, higher than the Q3, primarily due to lower byproduct credits and lower gold production. Full year 2022 cash costs were $297 per ounce, which was impressively below the low end of the annual guidance range.
Slide seven illustrates the growth in copper and gold production on the back of the $250 million in brownfield investments we delivered in early 2022. 2023 is expected to be another year of meaningful growth, with consolidated copper production expected to increase by 10% and consolidated gold production expected to increase by 30% compared to 2022.
Consolidated copper and gold production is expected to further grow in 2024 as a result of continued higher grades at Pampacancha and several gold production enhancements in Snow Lake. This is expected to lead to increasing EBITDA and cash flows. We believe our high-quality pipeline of attractive development and exploration opportunities will further add to this growth in the medium to long term. Slide eight highlights the details behind the 2023 consolidated production growth.
In Peru, the mine plan adjustments we saw in the Q4 continued into early 2023 to ensure steady operation of the plant during the regional logistical challenges. This is expected to result in more ore being mined from Constancia and less from the Pampacancha pit in the early part of the year. Despite these changes and a period of higher stripping at Pampacancha, 2023 production is expected to be 103.5 thousand tons of copper and 95.5 thousand ounces of gold, representing year-over-year increases of 16% and 64% respectively.
In Manitoba, 2023 gold production is expected to increase by 18% to 190,000 ounces due to higher gold grades and a 10% increase in ore throughput at the Lalor mine. The 2023 mine plan at Lalor reflects higher production from the gold and copper gold zones as those zones are expected to be prioritized over the base metal zones.
It also reflects a 10% increase in throughput at the New Britannia Mill, as the mill has been consistently achieving the levels above nameplate capacity. These mine plan enhancements result in 2023 gold production levels being consistent with the most recent mine plan for Snow Lake, but without the full ramp-up to 5,300 tons per day as we focus on maximizing the value per ton of ore at Lalor.
Year-over-year, zinc production is expected to decline by 42%, primarily due to the recent closure of the 777 Mine. We expect to release 2024 and 2025 guidance next month with our annual mineral reserve and resource update.
We expect our 2024 production guidance to be similar to the previously issued guidance, reflecting a further increase in copper production in Peru and gold production in Manitoba. More importantly, we now expect mining activities at the Pampacancha deposit to continue into the first half of 2025, which is expected to increase copper and gold production in 2025 beyond the levels shown in the most recent technical report.
Slide nine summarizes our cost guidance for 2023. Total expenditures are expected to decline by approximately $65 million compared to last year due to lower discretionary growth capital and exploration spending in 2023. Peru's sustaining capital expenditures are expected to increase year-over-year, but remain in line with the most recent technical report.
The high level of sustaining capital is due to an increase in heavy civil works for the completion of a tailings dam raise in 2023. Manitoba's sustaining CapEx is expected to be lower than 2022 due to lower equipment spending at Lalor and in the mills after the Snow Lake transition and ramp-up period in 2022. Total growth capital of $55 million in 2023 includes $10 million for mill recovery improvement initiatives in Peru and $15 million for the completion of the Stall mill recovery improvement project in Manitoba.
We have also allocated $30 million to growth spending in Arizona as we advance permitting economic studies and site works at Copper World in 2023. Total exploration expenditures of $30 million in 2023 are 61% lower than 2022 levels due to our focus on discretionary spending reductions. Our planned exploration activities this year are focused on areas with high potential for new discovery and mineral reserve and resource expansion.
These initiatives include permitting and drill preparation for the Maria Reyna and Caballito properties near Constancia, a limited drill program at Pampacancha to evaluate the potential to add an incremental mining phase at depth, and a winter drill program in Snow Lake focused on testing the deep extensions at Lalor.
Copper cash costs in Peru are expected to decline by 26% in 2023 versus 2022, primarily due to higher gold by-product credits and higher copper production. Gold cash costs in Manitoba are expected to increase in 2023 compared to last year as a result of the transition to a primary gold operation with lower by-product credits after the closure of the 777 Mine in June 2022.
Consolidated copper cash costs in 2023 are expected to decline by 30% compared to 2022 levels due to the increase in copper production and higher gold by-product credits from the increase in annual gold production. Consolidated sustaining cash costs in 2023 are expected to be 18% lower than 2022 levels due to the same factors affecting consolidated cash costs, partially offset by slightly higher sustaining capital expenditures.
Part of the discretionary spending reductions relate to deferred spending at our Copper World project. The reduced year-over-year spending at Arizona reflects our focus on project de-risking activities, including the completion of a pre-feasibility study, state-level permitting, and plans for bulk sampling program in 2023, as shown on slide 10. A majority of the technical work and expenditures related to the pre-feasibility study for phase one of Copper World are now complete.
The pre-feasibility study is expected to support the conversion of the mineral resources to reserves and optimize the layout and sequencing of the processing facilities. Pre-feasibility level engineering with the main processing facility was completed by year-end, together with geotechnical and hydrogeological site investigation activities. Metallurgical test work continued into 2023, and the results are being analyzed as part of concentrate leaching trade-off evaluations.
The pre-feasibility study results are expected to be released by the end of the Q2 of 2023. Copper World requires only state-level permits for Phase I. Late last year, we submitted applications for an Aquifer Protection Permit and an air quality permit to the Arizona Department of Environmental Quality, known as the ADEQ. We have been working closely with the ADEQ, and we expect to receive these two remaining permits in 2023. The other key state permit, the Mined Land Reclamation Plan, was received in 2022.
In January 2023, we received an approved right of way from the Arizona State Land Department that will allow for infrastructure such as roads, pipelines, and power lines to easily connect between the properties in our private land package. Upon receipt of the state permits, we expect to conduct a bulk sampling program to continue to de-risk the project by testing grade continuity, variable cut-off effectiveness, and metallurgical strategies.
We intend to initiate a minority joint venture partner process, which will allow the potential JV partner to participate in and help fund the definitive feasibility study activities in 2024. The opportunity to sanction Copper World is not expected until 2025 based on current estimated timelines and reflects a conservative approach to spending at Copper World over the next two years.
The 3P Plan for sanctioning Copper World that I mentioned earlier is laid out on this slide. This plan ensures Hudbay will be in the best position to move the project forward with the lowest cost of capital and the highest risk-adjusted return on investment.
Turning to slide 11, our recently executed surface rights agreement with the community of Uchucarcco allows for exploration of the Maria Reyna and Caballito properties. Hudbay owns the mineral rights to these properties that are located within trucking distance of the Constancia processing facility, and we completed geophysical surveys in the area that indicate large-scale potential at these properties.
Shortly after the community exploration agreement was completed, we commenced baseline environmental and archaeological activities to advance the permitting process for property drilling in the future. A ground geophysical survey commenced in the Q4 and will continue once the Peruvian social situation improves.
Our geological team commenced surface investigation activities, and field evidence confirms that both Caballito and Maria Reyna host sulfide and oxide-rich copper mineralization in skarns, hydrothermal breccias, and large porphyry intrusive bodies. Similar to Pampacancha, Caballito is located about 5 km from Constancia and includes an old open-pit mine that was operated by Mitsui until the early 1990s.
The U.S. Geological Survey from 1990 estimated a total resource of 91 million tons at 2.3% copper for the open-pit mine. Maria Reyna is approximately 10 km from Constancia, and artisanal mining activity is present in the high-grade areas. These small-scale miners report an average grade of between 2% and 6% copper in the ore. In Snow Lake, we commenced a winter drill program in January 2023, with four drill rigs testing the down-dip gold and copper extensions of the Lalor deposit.
This is the first time we have completed step-out drilling in the deeper zones at Lalor since the initial discovery of the gold and copper gold zones in 2009 and 2010. One additional drill rig is actively testing a target to the north of Lalor, which is another highly prospective location next to the main Lalor ore body that is thought to be offset by post-mineralization faulting.
The phase I of this program includes a total of 12 holes and over 20,000 meters of drilling, followed by a combination of surface and borehole electromagnetic surveys. Based on the results from the first phase program, a follow-up drill program is planned for the winter of 2024. We are committed to operating in a manner that demonstrates our focus on the environment. We are proud of our already low carbon footprint.
With over 50% of our total energy consumption being from renewables resources, including nearly 100% renewable energy in Manitoba, we are leading emissions rankings amongst peers, as seen on slide 12. We also align with the highest industry standards to ensure that we are on a par or ahead of industry expectations. We recognize we have a role in mitigating climate change. In December, we were pleased to announce our commitment to achieve net zero greenhouse gas emissions by 2050 and the adoption of an interim target of a 50% reduction in Scope- 1 and Scope -2 emissions by 2030.
We plan to be reporting on material Scope -3 emissions in the near term and continuing to be transparent with greenhouse gas performance data disclosure. Through our emissions reduction roadmap, we have identified multiple opportunities to achieve further reductions in emissions, including grid decarbonization in Peru, fleet and heating electrification, and fuel switching in mobile equipment.
We have been reporting greenhouse gas emissions data and performance to the CDP climate questionnaire for more than 10 years. Our annual sustainability report maps our CDP responses to the task force on climate-related financial disclosures recommendations. We are also aligned with the Mining Association of Canada's Towards Sustainable Mining or TSM protocols at all of our operations, with the goal to maintain a strong score of an A or higher for all protocols. We truly believe that our ESG principles are the foundation of our business and are critical for our long-term success.
Slide 13 summarizes our near-term cash flow growth and our high-quality organic copper pipeline. We believe that copper has the best long-term supply-demand fundamentals in the sector, as global copper mine supply will be unable to meet demand from global decarbonization initiatives. We have the highest near-term copper production growth and the highest leverage to copper among our mid-tier base metal peers. We have successfully increased our copper equivalent resources per share by more than three times 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. To summarize, we are a diversified mid-tier copper producer, as shown on slide 14. Our strong copper and gold production growth in 2023 and leading low-cost profile is expected to generate significant near-term cash flows. We also have a world-class organic growth pipeline offering medium to long-term copper production optionality.
As you've seen through this presentation, we have several exciting brownfield and greenfield growth opportunities that we intend to advance with our 2023 key strategic objectives. Our lower discretionary spending in 2023, together with lower year-over-year cash costs, will allow us to generate positive cash flow and advance our copper development pipeline with minimal capital.
We will continue to de-risk Copper World with several project catalysts expected in 2023 as we prudently advance our 3P Plan for Copper World sanctioning. In Snow Lake, it will be a year filled with several milestones as we execute the expansion and ramp up of Lalor beyond 4,650 times a day and complete the Stall mill recovery improvement program early in 2023. We'll conclude our drilling program to test the deep extensions at Lalor with the potential to expand gold mineral reserves and resources.
In Peru, we'll continue to progress Constancia's leading efficiency metrics by applying smart technologies to continuously improve operating performance, including sensor-based ore sorting and milling flow sheet enhancements. We also aim to further advance the Maria Reyna and Caballito satellite properties through exploration permitting. We will advance our climate change commitments by assessing opportunities that are aligned with global decarbonization goals.
Finally, we will remain vigilant in evaluating growth opportunities that meet our stringent strategic criteria that will reflect sustainable value for the company and our stakeholders. With that, we are pleased to take your questions.
Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. To join the question queue, you may press star then one on your telephone keypad. You will hear a tone acknowledging your request. If you are using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, please press star then two. Our first question comes from Fahad Tariq of Credit Suisse. Please go ahead.
Hi, good morning. Thanks for taking my question. Peter, maybe just on the Peru protest situation, can you talk a little bit more about, like, has the transportation of concentrate, is it just completely normal now? What about, like, supplies getting to the mine? It sounds like it's getting better. I'm just trying to understand, is it at normal levels now? Thanks.
Good morning, and thanks very much for the question, Fahad. I think look, the political situation in Peru is an interesting one, but it is one that our team has been able to respond to, I feel, in a manner that are entirely consistent with my expectations of their performance so far.
To your point, yeah, we concentrate transportation has certainly opened up in the last week or two, and we expect that it will continue along those lines w e think that the situation is starting to normalize, but it's a little bit difficult to predict exactly how it will go. What I can say, though, is that we are closer to our communities than ever, and so we will experience the ups and downs in the weeks and months ahead of us.
We have extremely strong support from our communities who have actually come out several times in order to sort of moderate the activities of protesters who come in from the outside. That said, I, you know, that's a long answer to your question, but I do expect we'll have ups and downs, but we will continue to be able to reduce the inventory that we have at site and progress shipments out of Matarani.
Okay. That's helpful. Maybe just as a follow-up. If you see then over the next several weeks that, you know, it's kind of very back to normal in terms of getting supplies to the mine, is it possible to rejig the mine plan to kind of go back to what it was previously, i.e., more Pampacancha ore?
I think, you know, it will take time. I'm sorry that I didn't really address your question about getting supplies to the mines, but we have been able to consistently get supplies to the mines t he biggest issue has been fuel, typically. We've adjusted the mine plan accordingly to be able to address any of the fuel bottlenecks. To get back to the mine plan as planned in the short term will be a little bit difficult. Perhaps I can ask Andre to elaborate on that a little bit.
Sure. Sure. The amount of fuel that we're getting into site as well as other consumables has been improving. That's been a positive trend. We were naturally in the previous mine plan going through a phase of stripping at Pampacancha in the Q1. With what, you know, in terms of managing fuel from the late December, early January, and into February, we prioritized our fuel to keep the mill running. Pampacancha is significantly further than Constancia pit and the other. With things started, we started getting back to Pampacancha just this past week, so as we were seeing our fuel levels go up.
It's probably a few months of stripping before we get back into the good grades again, so probably into the next quarter at this point. There's no magic scenario to get back and have it like the original plan. It's definitely gonna, you'll see the grades coming up into Q2.
We just sort of shift forward the plan that you would otherwise expect us to be operating against.
Exactly. Yeah.
Yeah.
Great. That's helpful. Thank you.
You're welcome.
Our next question comes from Orest Wowkodaw of Scotiabank. Please go ahead.
Hi, good morning. More questions are around the same lines in terms of Peru and Constancia. Can you give us an idea on your updated guidance for 2023, what does that assume with respect to the amount of Pampacancha ore that's going into the plant?
I think that as Andre, sorry, morning, Orest, and thanks for the question. As Andre said, that the next quarter is going to be focused on a lot of doing a lot of pre-stripping there, and we'll be preferentially mining at Constancia. I would say that we would push out in March, we would start to see the higher grades coming from Pampacancha again.
In terms of a volume number?
I'm sorry, what, could you repeat that, Orest?
Sure, yeah. In terms of a volume number, like, should we be anticipating that tons milled from Pampacancha is sort of similar to 2022, or could it even be less than 2022?
In terms of total metal, the year is backloaded. It's about 60% of the metal coming off at the back end of the year. We're not gonna see much Pampacancha ore until, you know, it's offset by about three months. With where we're at right now with. 'Cause we're just resuming it right now, so as we're getting going. I don't have an absolute number in front of me, Orest, but it is a reduction of what we had forecasted last year. But it's comparable in terms of. I think we're close to last year now at this point.
Orest, it's Eugene here. Just to, for some clarity around the guidance range. Our guidance range the midpoint of our guidance range contemplates getting back into Pampacancha in March. If you think about the range of possibilities from there, that's probably the outcome that, if you wanna model that appropriately, that's probably the best way to do it.
Okay. Thank you very much.
Our next question comes from Greg Barnes of TD Securities. Please go ahead.
Yes, thank you. Perhaps an easier way to think about it is you've shifted 15,000 tons of copper production from 2023 to 2025. Is that effectively what's happened?
I would say in general that's correct, Greg.
Around Snow Lake and Lalor and the 5,300 tons a day, I'm not sure I understand quite what the goal there is now i know you're shifting towards more higher grade ore and putting more through New Britannia, are you still planning to ramp up to 5,300 tons a day or not?
Yeah, I will let Andre provide a little bit more detail on that. In essence, the 5,300 tons per day that we envisaged previously included utilizing the ramp to get a bunch of the ore up. We find that the costs associated with utilizing the ramp actually squeeze the margins very significantly, are not an efficient use of our time and money. It is more cost effective to increase production through the shaft.
The specific gravity of the gold ore is lower, so it means that you have to ship more volume up the shaft. Our efforts at the moment are really focused on enhancing production through the shaft, but we will still move towards 5,300 tons per day A ndre, do you care to expand on that?
Sure. Greg, we are committed to increasing production. The plan for next year is about an 8% increase over last year's production. The differential that Peter was speaking to is the gold ores are a little bit lighter, maintaining where we're at right now at the plan, which is around 47, is already an 8% increase in volume movement. As we move forward into next year, like Peter said, it's inefficient to halt the ramp. I think in January, we hauled 18,000 tons, and it's a two hour round trip, and our scoops are waiting for the trucks to come back. We put a real heavy focus on getting more up the shaft.
There's a current, bottleneck. It's a short-term bottleneck that we're working through right now at all. We don't have a crusher underground at Lalor, and we ram our muck through grizzlies. Gold ore is harder, so we're working through a process to improve the grizzly design to have better flows through there. If you can imagine, we're shipping 18,000 tons up the hill at two hours a trip, going at 1 hour return trip from the stoves.
We could easily double that production from 18 to 36 without increasing our fleet into Lake, which is aligned with increasing to that end goal of 5,300 tons per day. We're hitting it on days right now, so we're hitting it on multiple days per month, but working through some of those little nuances will help us get to that goal.
How does this change, or does it change the production profile, from Lalor? I'm still not entirely clear.
The production profile is continuing to ramp up through the course of this year. By the end of the year, it's probably in the range of 4,700 tons per day a the same time, what we're working on is. They're complementary, we're also focused on cash, right. We're working on improving our dilution at the same time and sending less waste to surface.
Obviously, that counters production but improves cash. It's, we're trying to get better grades up from the mine and moving less waste, which is aligned with our greenhouse goals while increasing throughput. We have all the people in place to produce more, and right now we're working through, there's about five different process improvement things that are complementary.
They complement each other in terms of improving our development. Getting the right drill inventory in place as we're increasing up to about 200,000 tons of broken or blastable material and removing that bottleneck at the grizzlies, which allows us to use our trucks and improve the productivity at the stove. We're working on all those. We're, you know, as we resolve those, we'll have a better view on what is our final state, what will it be? Is it 53? Is it 52? Is it 54? We're working, we're working through that right now.
Okay. Okay, thank you.
Our next question comes from Stefan Ioannou of Cormark Securities. Please go ahead.
Yeah, thanks, guys. Just obviously great to see that, you know, you're doing certainly exploration at Caballito and Maria Reyna. Can you just remind us what the in terms of actually getting drills into the ground there, obviously some permitting to be done there from an exploration point of view, is that something that we could anticipate in 2024, or is it even longer-winded than that?
Hi, Stefan. Thanks for that. Yeah, I certainly do think that you could expect it in 2024 w here we are right now is we've sort of done the surface work that or the environmental baseline work that's required to make to submit applications for those permits. We've now submitted those applications or are on the point of submitting those applications t he next thing that follows is the review of the applications by the government as well as the Consulta Previa process.
We, we expect to I mean, it takes time, but we expect to get those permits in roughly a year. Certainly we would expect that, you know, right about this time next year, we would be we would have those permits. In the meanwhile, other additional surface investigations continue.
Okay, great. Again, I'm assuming there's still a fair bit of just sort of drill target definition to be done to really fine-tune that anyways.
Yeah, we've done a fair amount of that already. We have.
Okay.
I mean, really, the focus on our side has really been to see do we do sort of a much bigger drill program focused on the entire property, or do we look for sort of focus on a smaller area that would act as a sort of a high grade substitute or supplement to Pampacancha down the road. Those are the kind of things that we are reflecting on a s far as definition is concerned, we're pretty advanced.
Okay, great. Great. Then maybe just a vague question. I'm not sure how much you can actually say, but just, you know, on, in sort of that one of the last slides where you sort of you continue to evaluate and execute on, you know, growth opportunities. Look, looking outside the current portfolio, are you seeing a lot of opportunities that may compete with some of the internal organic growth stuff you're doing right now? Or is the focus really on sort of what you laid out in the presentation with the existing projects?
Look, I mean, I think one of the things that I've been fairly consistent about is that I believe that we have an extremely skilled team when it comes to highly efficient operations and world-class development of projects. We do feel that we can create value from both operating and development stage assets.
You know, we have this tier one development portfolio, and I've, you know, I've always said that we'd like to find a cash flowing operation asset, operating asset that adds to our portfolio to diversify our business. As I've also said, those opportunities are extremely scarce, but we continue to look for them, and we'll see what happens.
Yeah. Okay, great. Thanks very much, guys.
Our next question comes from Lawson Winder of Bank of America Securities. Please go ahead.
Thank you, operator. Good morning, Peter, Andre, and Eugene, nice to hear from you all. On the Pampacancha mine plan change, could it possibly be taken as a positive in the sense that it smooths out the copper production profile longer term? There's also the Constancia underground under consideration. What can you tell us about potential 2026 copper production from Peru? Could it now be similar in magnitude to 2025, as opposed to the drop-off in production that was contemplated in the last life of mine study?
Good morning, Lawson. Thanks for the question t he first part of it is, yes, I think you can take that as a positive. To the second part is that once Pampacancha is depleted, then we move into Constancia Norte. I think that, you know, it maintains grades a bit, at least, it maintains production. But it is, you know, over time, it does start to decline. To your point is 2026, you should sort of see us continuing at a rate of about 100,000 tons per year.
If I was to add to that, we're also working on a number of other process improvement projects. In our capital, you would've seen that we were deferring the pebble crusher. We were planning a trial early this quarter around rejecting pebbles from the mill, which are typically around 0.15 copper. We're looking at a trial of using it like a variable cutoff, where you increase the mine throughput, reject the pebbles, and get a much higher grade through the plant. We're looking at that test in the near future, and that is an opportunity for us to try to maintain and up in the 100,000 tons per year of copper post-Pampacancha.
As well, we've been seeing some successes with the ShovelSense. In terms of selectively re-removing waste from it, from the ore at the face, and we're, you know, the results to date have been looking promising. It's still in the testing phase, and we're looking to, we've, put aside probably 50,000 to 60,000 tons of material that we wanna run through the mill and just verify that the grades that we're sorting are in line t he combination of those two projects bode well for us to send better grade to the mill than what the current life of mine plan shows.
Okay, thanks for that, both of you. Then with the cash cost guidance, would you be able to help us by providing what the cost per ton assumptions are underlying those for both Peru and Manitoba as you've provided in the past?
Hi, Lawson, it's Eugene here. Yeah, this year we've evolved in our cost guidance. You know, in prior years, you would noted that we provided operating unit cost guidance, and then last year, we added cash cost guidance. In an effort to streamline the multitude of metrics that we guide to, we've reverted to kind of one metric per mine in terms of cost guidance. Cash cost per pound in Peru and cash cost per ounce of gold in Manitoba. The unit costs we will continue to report in our financials on a quarterly basis. You know, they are roughly in line for 2023 as projected from where we're trending.
Approximately $12 a ton in Peru and approximately CAD 200 per ton in Manitoba would be kind of a rough guide to where you get to. Similar levels, but we're gonna kinda stop from providing specific guidance for that while continuing to report.
Okay. Well, that right there is very helpful. Oh, sorry. Go ahead.
We'll note that the cash cost guidance for 2023 is lower than that in 2022. I think, you know, the story would be that we're producing more copper in Peru, more gold in Manitoba and at a lower cash cost, and that's a testament to the teams focus on cost efficiencies and despite the inflationary environment.
Yeah. That's fantastic. Thanks very much, Eugene. Thank you, Peter and Andre.
Welcome.
Once again, if you have a question, please press star then one. Our next question comes from Dalton Baretto of Canaccord. Please go ahead.
Thanks. Good morning, Peter and team. I want to start with just clarifying a couple of things that I heard on the earlier on the Q&A here. Andre, is it your intention to get to 5,300 tons per day at Lalor at some point in time? If so, when?
Yeah. Thanks for the question, Dalton. T he intention is to get to the right number. W e're optimizing a variety of scenarios, and the goal is to make more cash out of Manitoba. Guided in terms of the capital for Manitoba, I think we're spending about $75 million on capital development. A key focus that we're working on in the next year is trying to reduce our development cost by almost 20%, which will go right to the bottom line and improve the economics for future projects. The mine itself, we have the labor in place to move the material, so that's why we're running at a little bit higher cost.
Where we're at right now is there are some bottlenecks that creeped up on us that we weren't anticipating, particularly the fragmentation of the gold ore. The fragmentation isn't bad by mining standards, but because the ore is so hard when we're putting it through the breakers, it's causing delays on our trucks, and the delays on the trucks are translating to delays in the stopes because we side load our trucks. So what ends up happening is that right now they're hauling at the surface to keep production going.
We think probably within the next, you know, quarter or Q2, we're gonna be at a stage where we've solved that bottleneck at the shaft, and we'll start to see improvements in terms of our overall throughput going up the mine at a lower cost. At the same time, we're balancing off the development place to have the drill rooms and the drill inventory. We had a quite a turnover of people, if you will, over the last six months with the transition of people from Flin Flon to Snow Lake, and as well as within our management, almost 50%. It's quite a significant training exercise.
They're very skilled miners, the ones that are development miners for sure. All of those processes are going on i t'll be towards the end of the year that you start seeing it. First, like I said, on the previous call, you know, we're definitely hitting them on days. I mean, we've seen days over 6,000 tons per day.
The key is we have to get that reliably and balanced in our process. It'll be towards the end of this year and probably into the next to get to that peak level, if you will. It's a combination on of, it's not just chasing tons, is we're chasing value and cash. At the same time, while we're asking for more, we're asking them to blast less, to just mine the good stuff, the higher grade gold and avoid dilution and save on our tailings cost and milling costs and the like. It's a balanced conversation, w e'll have a better view on that as we go into the next quarters.
if I could add-
Yeah, go ahead.
If I could a little bit to that, you'll notice that our plan for this year results in an increase in the gold production guidance versus last year, or at least what was planned last year. That's, you know, due to some of these efficiencies that Andre talks about, we're gonna be running New Britannia now above 1,600 tons per day, which is above name plate.
O ptimizing the infrastructure we have to maximize the both production and at the lowest cost. In fact, maybe to reference a question that Urs asked earlier today, I want to clarify that we will be, our plan is to mine Pampacancha, an increased tonnage of Pampacancha this year. Even in this base case, it'd be about somewhere around 50% to 60% more ore mined at Pampacancha in 2023 than in 2022, even with the delays that we've noted due to logistics.
Thanks. That's helpful. Just to kind of put a pin in Lalor then. You know, it sounds like you're focusing on the gold at the expense of, you know, call it the zinc and, you know, overall tons. Is that sustainable, first of all, and what point in time do you think you'll come up with the right answer?
The answer, is it sustainable? The current resource base is more gold than base metals. In terms of the balance rate. Right now that's why we're doing the Stall recovery improvement program, or around getting better gold recoveries and copper recoveries. Because today we're producing more gold ore than what New Brit can handle.
Even though I think in January, we peaked close to 1,800 tons per day in terms of throughput at New Britannia. We're trying to push the limits there, but the challenge that we face right now is we have a surplus of gold ore relative to base metal. It's not a sustainability question. In terms of the overall, as we drive and increase our unit rates and bring our development costs down, it makes it easier to develop some of those base metal ores because they are less margin than the gold ores.
Okay, thanks. Then one more clarification on the mine plan at Constancia. Peter, I thought I heard you say that kind of post 2025, post Pampacancha, you're gonna move into Constancia Norte and keep the production level reasonably stagnant at 100,000 tons i thought Constancia Norte wasn't gonna come online until, call it, 2029. Just wondering if you could square that away for me.
The 2029 one would be underground. We would be going into Constancia Norte in 2023, so the open pit part of it in 2026.
Thank you. Then maybe just one last one for me. I just wanna switch gears to Copper World and the PFS that you're gonna publish by the end of Q2. I'm just wondering, have you guys decided on what your base case flow sheet's gonna be? Is it gonna be the same as the PEA? You know, we talked in the past about maybe a modular approach j ust wondering what you're gonna present as your base case.
Yeah. So right now we've completed all the engineering, for all the cost estimates for a variety of different treatment scenarios, whether it's shipping con, whether it's the Albion or some different pressure leaches. With all the costs in place and the engineering completing, right now we're going through the optimization of what makes the most sense. W e're honing in on what is the right number for us from a capital for the financials and the like s o we don't have that answer ready yet, and that's the optimization process that we're going through, feeding into getting it by the end of Q2.
Dalton, you know, to be sure that we are highly focused on minimizing the CapEx and maximizing simplicity, I think like we mentioned to you previously, that there is the ability to modularize some of this stuff t he question really is I think that your question is probably aimed more at the sulfide leaching process and whether we're likely to implement that. The question remains is, if we do it, to what extent do we do it? We're working all of those things at the moment.
Thanks, Peter. Maybe just one more on Copper World. On the site visit, we talked about the opportunity to maybe bring phase two forward, given your understanding of what the permitting requires. Are you devoting any resources or any capital right now towards fast-tracking that side of things?
No, we are not. We just believe that there's massive optionality there, because like I said, I think in my remarks, that there's $2.8 billion of NPV available to us upon a decision or upon sanction. We are dedicating absolutely zero time and effort and expense on that right now, as I focus solely on phase I.
Great. That's all for me, guys. Thank you.
Thank you.
This concludes the question and answer session. I would like to turn the conference back over to Candace Brûlé for any closing remarks.
Thank you, operator, and thank you everyone for participating today. If you have any further questions, feel free to reach out to our investor relations team. Thank you and have a great day.
This concludes today's conference call. You may disconnect your lines. Thank you for participating and have a pleasant day.
