Thank you for standing by. And welcome to the Evolution Mining Limited Full year 2023 Financial Results Call. All participants are in a listen-only mode. There will be a presentation followed by a question-and-answer session. [Operator Instructions]
I would now like to hand over to — excuse me. Apologies, to Mr. O’Connor. Again, that is Peter O’Connor. Please go ahead.
Peter O’Connor
Thank you, Andrew. My name is Peter O’Connor, the General Manager, Investor Relations at Evolution Mining. And welcome to everybody on the call today to Evolution Mining full year results call. We’ve lodged a range of announcements today on the ASX platform and we’ll be talking to those in this morning’s call and they include the announcement for the FY ’23 result, the full financials, including the 4E documentation, a presentation for the full year results and an additional release about the Ernest Henry Mineral Resource update as well.
Speakers on the call today include our Executive Chair, Jake Klein; our Chief Executive Officer and Managing Director, Lawrie Conway; our Chief Financial Officer, Barrie Van Der Merwe; and Vice President, Discovery, Glen Masterman who will talk specifically to the Ernest Henry Mineral Resource update towards the end of this call. Just to recap, the last quarter has been a very active period for external engagement for the Company and over that period of time, we’ve delivered a range of products, including our Investor Day in June 2020. We participated in several major global and domestic conferences through that period.
And importantly, we’ve also hosted a large range of investor groups through our operations over the last couple of months of Cowal and Ernest Henry operations in June, most recently in early August, our Mungari operation in Western Australia and we’re looking forward to a fourth visit, which will be in September this year to our Red Lake operation. We also look forward to the next couple of days where we have extensive investor meetings over that period for the balance of this week.
With that, I’ll hand over to Executive Chair, Jake Klein, to commence the call.
Jake Klein
Thanks, Rocky. Good morning, everyone. Thanks for joining us. Some of you were there, and remember that last week at Diggers and Dealers, I spoke to four key messages about the gold industry. This morning because I know how tired everyone is after watching the Matildas last night. I’m only going to ask you to remember three important messages about Evolution this morning.
So — and they’re on Slide 3 of the presentation and it starts with the business outlook and stronger cash generation. There’s no doubt that the outstanding resilience of our people and our [Technical Difficulty] recovery from the weather events at both Ernest Henry and Mt Rawdon this year, which resulted in over AUD150 million of delayed revenue at Ernest Henry alone. We have now fully recovered from these events, and have started FY ’24 with confidence. Having invested heavily in our portfolio over the last years — few years, we are entering a period of higher production and lower capital intensity. The next 12 months will be proof of this. This is the first message that I want you to remember.
The second one is that this morning, we have declared our 21st consecutive dividend showcasing that gold companies can consistently deliver returns to shareholders, whilst investing in growth. We are proud that we have now returned over AUD1.1 billion to shareholders with more to come. And as you will hear from Lawrie, the priority of margin over ounces will remain. We will continue with our cost discipline to optimize margin and ensure we bank the benefits of higher metal prices. We’re also really pleased that following our debt restructure last month, our investment grade credit rating was recently reconfirmed.
Thirdly, this morning, we released our fourth update to the mineral resource estimate at Ernest Henry. This is after only 18 months of full ownership of this operation. The deposit continues to grow. And as you’ll hear from Glen in a few minutes, it is truly emerging as a world-class ore body. So to recap our three messages this morning, firstly, lower capital intensity and higher cash generation going forward. Secondly, 21 consecutive dividends, a strong focus on capital management and confirmation of our investment grade credit rating. Thirdly, Ernest Henry is a world-class ore body.
Now, turning to Slide 4. Sustainability is integrated into everything we do at Evolution. The health and safety of our people, both physical and mental is a core value to us. We are pleased that our total recordable injury frequency rate reduced by 19%. But there is more we can do in this space and we will, as any person being injured is one person too many. Our strong social license is something we are very proud of.
We’re committed to improving outcomes for all our stakeholders. This commitment was reflected last week at the Annual New South Wales Mining HSEC Awards where we were awarded the 2023 Community Excellence Award, recognizing the long-standing partnership with the Wiradjuri Condobolin Corporation in establishing the Galari Agricultural Company to develop skills in indigenous youth. This collaborative shared value project has leased 50 (ph) acres of land for livestock production, renovated a farmhouse to become a cultural hub, and is successfully training and employing young indigenous people.
We are pleased that in FY ’23 — through FY ’23, through our team’s efforts, we achieved a 9% reduction in carbon emissions against our FY ’20 baseline. This puts us on the pathway to deliver our commitment of a 30% reduction by 2030. We also continue to advance the opportunity to convert the Mt Rawdon operation to a very large, multi-generational pumped hydro assets, which is effectively a giant battery. I remain convinced that not only will this be a very valuable asset to Evolution, but it will also be an opportunity to showcase mining and its contribution to our country in a completely different and positive ways.
With that, I will hand over to Lawrie.
Lawrie Conway
Thank you, Jake, and good morning, everyone. I’m going to touch on our FY ’24 plans before handing over to Barrie to take us through the details of the FY ’23 financial results.
Turning to Slide 5, which looks at our FY ’24 Group guidance, where we have planned 18% higher production, 6% lower all-in sustaining cost, and a 15% lower capital investment, which will be around AUD117 million less than FY ’23. This is all in line with our FY ’24 guidance released on our Investor Day of 770,000 ounces at an all-in sustaining cost of AUD1,370 per ounce, plus or minus 5%, and capital in the range of AUD640 million to AUD720 million.
As I said on the June quarterly call last month, we worked on finishing FY ’23 well so as to set ourselves up to deliver the improved performance in FY ’24 and ultimately, a lot stronger cash flow. Pleasingly, we started July well and are on plan. FY ’24 is about moving back to stronger cash generation, having moved past a peak period of capital intensity and setting the assets up for the long term. As Jake said, the priority on margin over ounces will remain, as will the discipline on costs, to optimize our margins and manage the impacts of inflation.
It is good to see some stabilization in inflation, but it does not mean we can reduce the attention on our margin. I also mentioned capital discipline and lower capital intensity on our Investor Day, with Mungari’s growth project essentially the only major project in execution phase for FY ’24. This shows our capital intensity is reducing this year. All other projects must justify their investment and will only be gated through to the next phase when investment is needed and justified.
Barrie will talk to the balance sheet strength shortly, but I want to reinforce that we are prioritizing reducing our debt levels and the FY ’24 plan is aligned to this. The metal prices are higher than what we achieved in FY ’23 and are higher than what our planned assumptions are. Each month if the metal prices remain higher, that extra cash will flow through to the bank account.
Moving to Slide 6 and a breakdown of the FY ’24 plan by operation. We expect to see improvements right across the portfolio. The production through FY ’24 will build up quarter-on-quarter, with the September quarter planned to be the lowest quarter as we complete major maintenance on a number of our mills. As we move into the second half of the year, the production is expected to be materially higher as both Cowal Underground and Upper Campbell at Red Lake ramp up. Our all-in sustaining costs will mirror this ramp up in production and trend down through the year.
Briefly on each operation, Cowal is expected to increase production by 16% in FY ’24 to around 320,000 ounces, which will be another record year. Cowal fully repaid all invested capital by the end of July, including the capital for the underground mine, and is now set to be a strong cash contributor again. Ernest Henry is back to full production and will revert to the material cash generator it has been for many years. Mungari will continue its consistent performance at 130,000 ounces at a 7% to 8% lower all-in sustaining costs compared to FY ’22 (ph). The growth project will ramp up during the year and remains on plan.
Red Lake has been able to set up to deliver an improved and reliable performance in FY ’24, with the higher grade material at Upper Campbell to be achieved in the second half of the year. The reduction by 10% of the workforce is on track to be completed this quarter. Mt Rawdon is now back into the pit, which provides access to the higher grade material, resulting in a lower all-in sustaining cost and improved cash generation.
Overall, we are well placed to deliver improved performance this year, which will result in stronger cash generation, at the same time, advancing the strong pipeline of opportunities we have, so as to deliver higher returns over the long term.
With that, I’ll now hand over to Barrie.
Barrie Van Der Merwe
Thank you, Lawrie, and good morning, everyone. We’re on Slide 7 now. FY ’23 was a year during which challenges like the weather events were managed well and showed the resilience of our people and our high-quality, low-cost asset portfolio. Underlying profit after tax of AUD205 million was materially impacted by weather, and I will unpack that further on the next slide.
EBITDA and EBITDA margin remained strong and was only marginally down compared to last year, despite the weather impacts. Adjusting for that, EBITDA would have been approximately 15% higher, with EBITDA margin at about 47%. Operating mine cash flow of AUD944 million was 6% higher, and the Group cash outflow for FY ’23 of AUD116 million was driven by peak capital expenditure in organic growth.
Adjusting for the weather events, Group cash flow would have been approximately AUD20 million positive. The Board declared a fully franked AUD0.02 per share final dividend for FY ’23, as capital intensity is reducing and we expect strong cash generation.
On Slide 8, the weather event in March at Ernest Henry had a material impact on profitability and cash flow in FY ’23. The estimated revenue loss compared to last year was AUD150 million. This was partially offset by owning Ernest Henry 100% for the full year, which contributed AUD65 million to profit before tax, compared to FY ’22. An increase in gold ounces sold added AUD58 million to profit and a higher gold price of AUD112 million.
Excluding the weather impact and a full year of ownership, copper revenue was down by AUD28.5 million, driven by lower year-on-year production, as originally guided. Operating costs increased by AUD87.1 million, driven by a 5% inflationary cost increase of AUD71 million, AUD40 million of additional costs to recover from weather events, partially offset by operational efficiencies and a higher level of capital development across the Group, which resulted in more costs being capitalized compared to FY ’22.
Depreciation was AUD38 million higher due to the amortization of the purchase price allocation at Mungari, higher asset-gating amounts at Cowal and Mt Rawdon approaching the end of its life as a gold mine. Underlying profit after tax was AUD205 million after adjusting for non-recurring items as outlined on the slide and the tax effect.
Turning to Slide 9. Our cost drivers and their weighting remain consistent. Labor, including contractors, is almost half of our cost, and the top seven categories comprise approximately 80% of the total. This allows us to focus our management efforts on the cost elements that really matter. The labor market remains tight, and we expect labor costs to increase by around 5% to 6% in FY ’24.
Year-on-year Australian CPI for the June quarter was 6%, down 1% from the March quarter, which was more than offset by the increase in the AUD gold price over the same period. Our cost guidance includes adequate provision for inflation in FY ’24. We have a high level of contracted spend that helps to control cost. Electricity is a good example, where supply is locked in for between two to eight years, with Cowal on a fixed-rate contract until the end of 2030, at favorable rates in a very competitive [indiscernible].
Our focus on sourcing and efficiency improvements will continue. Our cash flow and cost drivers are well understood, and key sensitivities are set out at a high level on the graph bottom right. If the spot gold price prevails through FY ’24, then compared to the FY ’23 achieved price, cash flow would increase by approximately AUD270 million, which will contribute to our commitment to delever the balance sheet.
Turning to Slide 10. With capital expenditure peaking in FY ’23 and expecting strong cash generation in FY ’24 and beyond, the Board declared a fully franked dividend of AUD0.02 per share, our 21st consecutive dividend, which cumulatively now amounts to over AUD1.1 billion. The dividend will be paid on 6 October to all shareholders that were on the register on 31 August.
Our balance sheet is strong and flexible. Our investment grade credit rating was reconfirmed last month, which underscores the quality of our asset portfolio and the expected cash generation. Following the debt restructuring announced at our Investor Day, debt maturity is aligned with extended mine lives, with an average debt tenor, 7.5 years. We have no debt settlement commitments until Q2 of FY ’25.
Our average cost of debt is a low 4.7%, with 80% at an average fixed rate of 4.5%, which compares very favorably with current market rates, considering that the 10-year US Treasury rate increased by about 50 basis points since we locked in the rates of our most recent US Private Placement. We use hedging only for risk management purposes, and the previous hedge book, with pricing well below current spot levels, was fully delivered by June 2023. Going forward, 95% of our production is unhedged.
During FY ’23, solid foundations were laid to set the Evolution up to deliver in FY ’24 and beyond. The balance sheet is strong and flexible to enable the execution of our strategy, and we expect that debt will start to reduce in FY ’24.
I will now hand you over to Glen to talk about the exciting resource update at Ernest Henry (ph). Thank you.
Glen Masterman
Thank you, Barrie, and good morning, everyone. I’d like to direct your attention to Slide 11 of the presentation. This latest update at Ernest Henry is our fourth mineral resource declaration in 1.5 years, reflecting an excellent rate of growth at this world-class copper-gold ore body. During this period, Evolution has grown the resource by 700,000 ounces of contained gold, which equates to a 41% increase, and by 390,000 tonnes of contained copper, which equates to a 44% increase. We’ve completed this resource update now in order to inform the feasibility study with the most up-to-date information.
Another resource update is scheduled as part of our annual MROR cycle at the end of 2023 and will incorporate another three to four months of [Technical Difficulty] Overall, the mineral resource has increased to 102 million tonnes, grading 1.25% copper and 0.73 grams per tonne gold, representing a 7% increase by tonnes, a 5% increase in copper metal, and a 3% increase in gold metal. This update is based on only 26 new drill holes and incorporates only two months of underground drilling from the first half of 2023.
The long section on Slide 11 allows us to visualize from where the growth has occurred. The main additions come from the connector zone linking Ernie Junior to the lower lenses of the main ore body, which is highlighted by the dashed green line, as well as from expansion of the main ore body below the 775 meter RL.
Metal addition outside of the Feasibility Study footprint that is situated between the 1,125 meter RL and the 775 meter RL has the potential to become a future source of production that could help sustain current production rates over the full 17-year mine life extension out to 2040. The attractive aspect of adding metal in this location is that we expect we will be able to potentially utilize infrastructure that will be in place in support of the mine extension, which is currently the subject of the Feasibility Study, which is expected to be completed in the March quarter of 2025.
With that, I’ll hand back to Lawrie.
Lawrie Conway
Thank you, Glen. The results we continue to see out of Ernest Henry are amazing and they do give us confidence of a much better life at what is already a world-class asset.
In summary, on Slide 12, we have a portfolio of assets where we’ll continue to prioritize margin over ounces and maintain our focus on safely and reliably delivering to plan. We’ve been successful to date in increasing the mine life of each asset and have further upside for either mine life extensions or margin improvement. This will enable us to deliver sector-leading returns.
We have the flexibility to time these projects and we’ll continue with our capital discipline. Doing this will allow us to deliver material cash flows through the cycle and importantly, capture the benefits of current metal prices, which will lead to increased returns to our shareholders.
Thank you for your time this morning and Andrew, please open the line for questions.
Question-and-Answer Session
Operator
Thank you. [Operator Instructions] Your first question comes from Hugo Nicolaci with Goldman Sachs. Please go ahead.
Hugo Nicolaci
Morning, Jake, Lawrie and team. Thanks for the update this morning. Maybe just first one on Ernest Henry and good to see the resource update there this morning. Maybe one for Glen. Just wondering if you could remind us if there’s anything else outstanding to move to that next level of study on the extension and reserve update and what the timing on those looks like at the moment. Thanks.
Glen Masterman
Yeah. Thanks, Hugo. So, yeah, we’re currently — we’ve commenced the Feasibility Study on that mine extension footprint, so just turning to Slide 11, that area of the ore body that is currently the subject of the study is highlighted by the magenta dashed line there. So what we’re expecting to do is, over the course of the Feasibility Study, is to continue to infill drill and convert any of the sort of inferred blocks that continue to exist inside of that footprint so that we can then transition those resources into reserves. We expect the next reserve update, that Ernest Henry will be released alongside the Feasibility Study, which is expected to be ready in the March quarter of 2025.
Hugo Nicolaci
Great. Thanks for that, Glen. And then next one, just on costs, the team, appreciate the detail on the cost breakdown and the sensitivities in the pack. Just wondering if you could provide a bit more color on the labor market tightness comment. Is that still reasonably broad-based or still, more specialty underground operators? And how have you seen that change, if at all, in the last couple of months since the strategy day? Thanks.
Jake Klein
Thanks, Hugo. Look, I mean, I think if we look at it, it still is West Coast, East Coast, and then obviously in Canada, for start in Canada, we’ve got still low turnover at Red Lake, the restructuring of the workforce also going on. So, yeah, we don’t see as much tightness there other than attracting technical professionals into the region. On the East Coast, we certainly have seen it stabilize quite a bit. Cowal has a good, I guess, access in the Central West of New South Wales to people. And Ernest Henry is on a FIFO arrangement.
When we look at the West, at Mungari, we have seen, as we presented on site last week, the turnover rate dropped from 40% about 12, 14 months ago now to just over 20%. So we are seeing an improvement there. I think also as we’ve got 25% of the workforce is now on a FIFO arrangement, having picked up Kundana and East Kundana, that has alleviated some of the problems. But in terms of our area with the most difficulty, it still remains in the West in Mungari.
Hugo Nicolaci
Great. Thanks for that extra color. And then last one, just maybe for Jake, favorite subject on Mt Rawdon Pumped Hydro, any updates there and how that’s progressing?
Glen Masterman
Yeah. Thanks, Hugo. I appreciate you asking that question. Hopefully, there’s many more to come on that. Look, it’s progressing well. So the engagement with the Queensland Government is increasing. It’s clear that as they’re defining their strategy better, that the Mt Rawdon Pumped Hydro opportunity clearly strategically is an important part of that. So the engagement is ongoing as we’re completing the Feasibility Study or advancing the Feasibility Study.
We’re now talking extensively with Queensland government departments. We’re talking to Powerlink, and we’re talking to the Queensland Government entities that are natural potential owners of an asset like this. So that is in addition to speaking to other energy retailers who’ve all expressed some interest. So conversations are ongoing, and I’d say, it’s constructive and positive.
Hugo Nicolaci
Great. Thanks for that, Jake. I’ll pass it on.
Operator
Your next question comes from Matthew Frydman with MST Emerging. Please go ahead.
Matthew Frydman
Sure. Thanks. Morning, Jake and team. Thanks very much for the update. Maybe just firstly to Glen, and thanks for all that color on the resource update today. I just wanted to clarify, you highlighted the magenta area there in the orebody that is the target of the Feasibility Study update. Is it your intention to continue including these additional — these — I guess, the additional resources from these updates and further incremental drilling? Is it the intention to include that ultimately in the Feasibility Study? Or is that magenta area the clearly defined outline of what’s being considered for the Feasibility Study?
Glen Masterman
Yeah, Matt. So what we’re doing there is — so you’re right, the magenta outline is the footprint of the current Feasibility Study. The drilling program will continue over the course of time to infill and define the orebody inside the magenta area, but we’ll also be doing work inside the green-dashed area. With the idea that we will — we’re going to bring that sort of connector area at Ernie Junior, up alongside the mine extension study in terms of our knowledge of it, to the extent that we can understand how we may optimize infrastructure that would support production in that area. But that Ernie Junior to sort of lower lenses of the main orebody won’t be at Feasibility Study level by the time we complete the study for the main mine extension area.
Jake Klein
Matt, just to add to that, because it’s a — it is a good question, and we actually discussed it yesterday when we were talking about this call and the release. All the infrastructure is considering all the new drill data and is being located in places that will be optimal to access this additional mineralization as it gets upgraded into reserve and Feasibility Study status.
Matthew Frydman
Yeah. Got it. Thanks, Jake. Clearly, a big chunk of the resource growth today is coming from that area. So, obviously, very important to consider that — putting infrastructure there. Is there any particular reason, Glen, why you don’t think it will be up to that reserve level? Is it just in time for the study? Is it just a function of the drilling density and obviously, focusing on infill in the priority areas rather than extension in those additional areas outside the footprint? Is that the driver there?
Glen Masterman
Yeah. That’s — it’s just a timing aspect there, Matt. So yeah, look, we’ll do what we can to sort of catch it up but we don’t feel that it’s going to be quite ready to be included in the actual Feasibility Study. But as Jake mentioned, we’ll consider all of that information in terms of how we optimize infrastructure and development.
Matthew Frydman
Got it. Thanks very much for that. Maybe switching over to the financials. Obviously, ending the half with 46 — or ending the financial year, I should say, with AUD46 million in cash. Clearly, that’s just a point in time, but it’s probably been five or six years since you’ve ended a period with cash at that level. So I guess, looking forward, you’ve talked about the cash generation of the business improving over FY ’24. But clearly, there’ll be swings and roundabouts. I’m guessing that you’re going to need to draw down at times and rely on that revolver facility at times.
So just wondering if you can talk through — maybe Barrie, if you can talk through I guess, what are the costs associated with using that facility? You mentioned, I guess, Group-level average interest cost of 4.7%. Can you talk through the specific costs associated with utilizing that revolver facility?
Lawrie Conway
Yeah, Matt. I’ll hand that to Barrie around the actual facilities and the revolver. But I think we finished the year at AUD46 million. We — as we had started FY ’23 with over AUD570 million of cash, knowing what we have to do through FY ’23. I think then — when you overlay it with the Ernest Henry impact, that had a material effect. So when we look at the move into the start of FY ’24, as Barrie outlined, the — and Jake did, the revenue loss was around AUD150 million and the extra cost we had to incur through the recovery, those things fall away.
So through the first three to four months of this year, that Ernest Henry back at normal production is the source of cash flow. You then also overlay it with, as I mentioned, Cowal now reverting back to a net cash versus the investment in the underground. So that’s what gives us that cash generation in the near term. It builds up through the course of FY ’24, but as we have other commitments, that revolver will come in and out, and Barrie can touch on the cost of those.
Barrie Van Der Merwe
Yeah. So let me just briefly, on the revolver, so let me remind everyone, it’s a AUD525 million facility that we’ve got available to provide us with that additional liquidity. It’s a variable rate facility and it runs at current rates at about 6.1%. And important to note that you can go in and out of that facility fairly [Technical Difficulty] down and then repay very quickly. So you can manage it quite efficiently and don’t have to carry the balance for a long period.
Matthew Frydman
That’s pretty clear. Thanks for taking my questions.
Operator
Your next question comes from Daniel Morgan with Barrenjoey. Please go ahead.
Daniel Morgan
Thanks, Jake and team. Our first question is the stamp duty, which is still outstanding. Is there a latest expectation for when that might need to be paid?
Lawrie Conway
Yeah, Dan. As per previous calls, we — the obligation is within a month of receiving it, and we’re pleased to say that the one-way communication remains in place.
Daniel Morgan
Okay. Very good. Next question, just in the weeds of the accounts, I note that there’s AUD20 million in deferred revenue at Red Lake. What does that pertain to? What’s going on there?
Lawrie Conway
So this is accounting standards coming into play again then. So we had the concentrate buildup during the year and it was always planned to be sold in the June quarter. We were paid for that concentrate. But because it hadn’t fully left sight and title hadn’t transferred on 30 June, we couldn’t book that as a sale. So we have to book the cash as deferred revenue, and then we book the ounces as a sale in this year. And therefore, that’s why it’s on the balance sheet the way it is. So cash received in June quarter, sales recognized in FY ’24.
Daniel Morgan
Right. Okay. I’m sorry to still be in the weeds of the accounts. Just in Note 13 of your accounts, you do have a big step down in trade receivables, but you do have a new item of AUD70 million in accrued revenue. Is this a reclassification now that you’ve taken full ownership of Ernest Henry where concentrate used to be in trade receivables, now it’s an accrued revenue? Or perhaps can you just explain what’s going on there? Thank you.
Barrie Van Der Merwe
Dan, I’ll have to look at that one to just make sure. I suspect it has to do with bringing on some of that Ernest Henry receivable, but let’s confirm that one for you.
Daniel Morgan
Okay. Thank you. And then just last question. I mean this quarter is generally one at which maintenance occurs at all sites. So I presume that is the case. Maybe just a quick comment on did the maintenance activities at the various sites go to plan? Or is there anything you might call out?
Lawrie Conway
Yeah. So Dan, I think the biggest one is at Cowal, and the second one is at Ernest Henry. So Cowal’s was this month. It was over 150 hours that is running on schedule and expected to be completed in this month. So that’s good for Cowal. And similarly, at Ernest Henry, which is both the mining and the plant. So we basically try and run those sequentially in the same quarter, and that’s tracking to plan, again, to be done within this quarter.
Daniel Morgan
Okay. Thank you very much for all your answers.
Operator
Your next question comes from Rahul Anand with Morgan Stanley Australia. Please go ahead.
Rahul Anand
Hi, team. Thanks for the opportunity. I might start with an accounting question perhaps. Just continuing on, look, in terms of the working capital, I just wanted to touch upon a couple of things. You had a small release for working capital this period circa AUD10 million. And the key drivers there were about a AUD200 million build in your trade and other payables, which offset a large portion of your inventory build, which I would have expected as you bring back production. So could you talk a bit to that in terms of the trade and other payables? And are you expecting those to reverse in this half?
Lawrie Conway
Yeah. Look, Rahul, it’s one that depends on each of the operations. And so when we look at it, the payables built at the end of FY ’23 as those projects and our major capital was large in the June quarter. So they work their way out through FY ’24. When we look at inventory, that’s more at the moment based on Stage H in — at Cowal. So when we go into FY ’22, there was a period where we drew down the inventory as we were continuing — finishing off the waste stripping through FY ’23 as we access the ore, then therefore, we well and truly outlined the processing plant. So that built up.
And when we look into FY ’24, now that Cowal is back into full operations at the pit and really mining ore only, that inventory will build through FY ’24 again. When you then look at it over the course of a year and as we looked at the June quarter and the full year results when you look at the financials, the net movement in working capital isn’t that material by the end of the year.
Obviously, in the second half of FY ’23, that was impacted by the Ernest Henry outage where we weren’t producing for a couple of months and then started to build up production. So what we would see through the first quarter of this year, those receivables will lift because concentrates settled over a three to four-month period, and then it will stabilize again. And that’s why I say we try to look at it on a full year [Technical Difficulty].
Rahul Anand
Yeah. No, fair. I was talking more towards the full year number conscious you have Ernest Henry ramping up. So, in terms of some — the payables then, they’re sort of at the level where there should be now, is that how I should read that?
Lawrie Conway
Yeah. Look, what we would see through FY ’24 that [Technical Difficulty] down. So, therefore, it will be a draw on working capital over the year because our capital intensity this year is, as I said, is about AUD117 million lower. Therefore, the capital that we spent in the second half of FY ’23 will be flow-through, get paid, and therefore, the payables won’t build up as much as it did in FY ’23.
Rahul Anand
Got you. Okay. That’s clear. Thanks for that. Look, second one, still for yourself and perhaps Jake and Lawrie as well, dividend policy. I guess, August 2019 was the last update there. And it is sort of indicating a 50% payout based on free cash. Obviously, a tight period or a negative period for free cash at this point in time, but still that dividend payment. Should we read that or should we read the AUD0.02 per share as a minimum dividend payment perhaps? Or how should we think about that dividend policy going forward?
Lawrie Conway
Yeah. So look, I mean, the dividend policy, we discussed it again with the Board this week in finalizing the accounts. We don’t see a change to that in the near term. We do think it’s based on cash flow. And as Jake mentioned, making sure that as we then come out of this intensity, we turn our attention to returning dividends to shareholders. It’s not so much that AUD0.02 will become the base. It’s more that as we look into FY ’24 and ’25 cash flow increases, and therefore, that policy will have a role to play, whereby we would expect that the dividend lifts from this base. When finalizing the FY ’23 final dividend, it was really on the outlook rather than — because if you take 50% of negative cash for a year, we’d have to ask the shareholders for money, but that wasn’t the plan.
Jake Klein
And I think just to add to that, I think it reflects a discipline and a recognition that we’re using shareholders’ money, but we had a very capital-intensive period but we thought it was appropriate and think it is appropriate to recognize shareholders. And it reflects the fact that we’re entering and we’re confident we’re entering this period of lower capital intensity and higher cash generation.
Rahul Anand
Understood. Okay. Look, a final one, perhaps a follow-up for Glen, Ernest Henry. Glen, you were talking about the green area, perhaps providing the upside in terms of the resource and you’re also talking about the thought process going into the infrastructure side. Is there a scenario here whereby firstly, if your findings in terms of additions to resources are better than expectations that perhaps there is a change in scope of the project and you consider perhaps a bigger footprint, perhaps more processing, et cetera, et cetera? I mean how should we think about how, firstly, these results have come in versus your expectations? And then secondly, potentially, how can they change the scope? Thanks.
Glen Masterman
Rahul, yeah, look, I think it’s — well, I’m really pleased that the results, I think, have exceeded our expectations when we took ownership of the asset. But as we started to develop more knowledge of the orebody, we’re able to start predicting where we would be able to establish future growth. So it’s pleasing that that’s being confirmed by the current drilling. And as we’ve mentioned previously, we still believe that there’s definitely more to come.
And I think an area, for example, is Bert, which may be a separate mineralizing or mineralized trend that is sort of plunging down parallel to the main orebody. And we’ve got two surface diamond rigs on site at the moment drilling. So that’s — it’s another area that we’ll be sort of looking forward to the drilling results coming forward.
I guess in terms of your question around study scope, we — the scope at the moment is to look at the main orebody mine extension inside of the footprint that we’ve highlighted on the long section there. And the reality is that that’s more advanced in terms of our orebody knowledge, and that’s in sort of the life of mine production sequence. So we’re not going to change the scope of the study at the moment, But Ernie — that Ernie Junior area and down plunge will become part of a separate study that we will continue to drill.
And the reality — and the reason why we won’t necessarily sort of delay or change the scope is that we won’t be able to get Ernie Junior into the reserve alongside the main orebody footprint there or extension footprint in time just because we’re prioritizing drilling in that feasibility study footprint area, mainly to get a lot of the inferred or some of the inferred that sits in there, we need to convert that up to an indicated resource so it can be classified as a reserve. And so we just have to prioritize our drilling there. And then as we infill Ernie Junior that becomes part of the story.
Jake Klein
Yeah. And I think just to add to that. It’s a fantastic position to be in for an orebody. I think Glen was being modest when he said it’s exceeded our expectations, the drill results. I mean we’ve added 50%, almost 50% to the copper and gold resources in only 18 months. And I think it’s — this asset is going to be the subject of multiple studies going forward. The most important thing for the Feasibility Study is really to lock down the infrastructure.
And in the time between now and when we’ve completed the Feasibility Study for Glen to have drilled in and around these extensional areas so that the infrastructure is located in an optimal way, even though that — those additional areas may not be included in the Feasibility Study. But it’s really about getting the infrastructure in place and then looking at subsequent studies to bring that into production and extend the mine life. So upside is the key theme at Ernest Henry.
Rahul Anand
Understood. That’s helpful. Thank you, team. I’ll pass it on.

Your next question comes from Andrew Bowler with Macquarie. Please go ahead.
Andrew Bowler
Good day. I think there’s been a few accounting questions asked thus far, but always room for one more. Just in terms of Red Lake, rightsizing of the workforce there, I’m just wondering if you can give us an indication of what that cost could potentially be and what sort of P&L impact we could expect in FY ’24, I guess, particularly in the first half of FY ’24. Thanks.
Lawrie Conway
Yeah. So the 10% reduction is expected to be about a AUD10 million, AUD12 million cost, Andrew, and that will go into the P&L as a cost in the first half of the year, depending on the actual cost we’ll hit there. But as we said, the annual benefit from that is expected to be around AUD10 million per annum.
Andrew Bowler
No worries. That’s all from me. Thanks, guys.
Lawrie Conway
Thanks, Andrew.

Your next question comes from Al Harvey with JP Morgan. Please go ahead.
Alistair Harvey
Yeah. Morning, team. Just one on the resource — Ernest Henry resource for Glen. Now, it’s only a small amount of drilling that’s going into that update, and it’s relatively minor, but grades do still look like they’re ticking down. So just trying to get a sense of what part of that new material kind of like the grade dispersion, so what — how is the grade of Bert look versus Ernie Junior versus the new material below the 775 meter RL?
Glen Masterman
Al, the grade is reasonably consistent between most of the ore bodies, minor sort of shifts between each of them. I think what we’re seeing in the — in this update is there was a big chunk of indicated mineralization in the mine extension footprint that was upgraded to measured classification, and what that did was refined our understanding, particularly of the higher-grade gold domains in the — in that FS footprint area. So what that’s done is it’s basically put greater definition on the domaining shapes that we use and have sort of restricted the influence of some of the — some of those higher gold grades based on our current understanding.
Having said that, those gold domains, which also carry higher copper remain open at depth down plunge. So there is the ability to continue to expand — extend those with our future drilling programs. But that’s sort of — that’s kind of the impact that you’re seeing on the resource grades in this update.
Alistair Harvey
Great. Thanks, Glen. And just quickly, is it the copper grades do improve with depth or gold grades or both?
Glen Masterman
What we’re seeing is just a slight change in the gold-to-copper ratio, where gold is higher on a relative basis than the copper.
Alistair Harvey
Great. Thanks, Glen.

Your next question comes from Sheila and Howard Mills with Stock & Station Services. Please go ahead.
Howard Mills
Yeah. Thanks, Jake and your team. Just probably one for Glen here. On Slide 6, you’ve got Ernest Henry all-in sustaining costs of, from what I can see, minus AUD2,000. How did you treat that? I’m just having trouble working out how you got to your AUD1,450 current all-in sustaining costs. Does that mean you were not sort of booking that?
Jake Klein
Yeah. We treat the copper as a by-product credit. So that’s what helps bring the average cost down. But yeah, Ernest Henry is very low cost and is negative.
Howard Mills
Yeah. So the copper’s a by-product or the gold’s a by-product?
Jake Klein
The copper’s a by-product, yeah. But as Glen finds more and more copper, it is turning into a copper-gold ore body in the true sense of the word. But we treat the copper as a by-product credit. If you still think about it in gold equivalents, it’s about 300,000-plus ounces of gold equivalents as production base.
Howard Mills
No problem. A lot of thanks for that, Jake.
Jake Klein
Thanks.

Your next question comes from ABC News — Jarrod Lucas of ABC News. Please go ahead.
Jarrod Lucas
Yeah. Good morning, guys. Just was interested in a few of the logistics around the Mungari expansion ramp-up here in Kalgoorlie, if you could talk to that. I don’t know what that construction workforce is likely to peak at.
Lawrie Conway
Yeah, Jarrod. So the workforce will ramp up. It’ll be about, for the construction, 250 to 275 people needed in the latter stages of installation of the facility. As we said, it’s a 30-month build. We’ve got around a 60-week lead time on the major items for the plant. So it’s sort of at least a year, year and a half in before we need to see that ramp-up in the construction workforce.
Jarrod Lucas
Are you having any issues around potentially housing that construction workforce? And just note the number of construction projects in this part of the world at the moment, I mean, the Super Pit, for example, has got about 600 construction workers incoming for its Fimiston expansion.
Lawrie Conway
Yeah. Look, I mean, it is definitely tight for accommodation over there even with Diggers, people staying in caravans. I think it’s showing that there’s not a lot of housing around. The good thing for this project, one, it’s not of that size and scale of the Super Pit. In terms of — we’re down the short list in terms of the contractors for the construction and both parties that were on the short list, we have identified not only the workforce requirements that they can meet, but also the accommodation for that workforce.
So the pleasing thing for the project there is that the contractors we’re looking at are already thought of the accommodation requirements and have identified the way they’ll be able to provide that, which will be temporary accommodation and villages coming into the area.
Jarrod Lucas
Awesome. Last one on that. When do you think you’ll award that — those contracts?
Lawrie Conway
The main contracts are expected in the December half or if not early in the March quarter of FY — of 2024 calendar year. So it’s within the next six months. The ramp-up has been we’ve been going through the design and confirming all of that with the engineering and the contractor. And then we’ll go through the final selection process in the next few months.
Jarrod Lucas
Fantastic. Thanks for that, guys. Appreciate it.
Lawrie Conway
No problem, Jarrod.

Your next question comes from Jon Bishop with Jarden Group Australia. Please go ahead.
Jon Bishop
Morning, guys. Thanks for taking my questions. Just a couple of quick ones. You flagged the Navarre Minerals write-down in your June quarter. It’s probably a reflection on me rather than you, but whereabouts, did that occur in the P&L, and what was the final amount?
Barrie Van Der Merwe
Yeah. So Jon, the final amount was AUD13.8 million, and that went through the other costs in the P&L. So if you look in Note 2, you’ll find it there in other costs of the income.
Jon Bishop
Great. Perfect. Yeah. As I said, it was probably more a reflection of me. So thanks for pointing that out. And just quickly on Cowal OPC, could you remind me again of the timing of that consultation process and final investment decision? And then leading on from that, what sort of approximate amount we should be thinking about for capital and the spread of that capital in terms of timeline?
Lawrie Conway
Yeah, Jon. The public display closed in this — in the last few weeks. That’ll then go through the normal regulatory process where they look at those submissions. Pleasingly for us, the number of submissions were overwhelmingly positive, with over 100 out of 112 being positive. We’ll then wait for the regulator to come back with their position, having assessed all of those submissions. We then go through the process of responding to those. We still have allowed at least a 12-month period, depending whether it gets sent through the IPC or not, and then we will go from there.
In terms of timing, as we said on the Investor Day, I mean, realistically for us, we’ve got a lot of flexibility around the timing of that project. We would see that as mining of the E42 pit comes off, we’ve got the stockpile material. So it’s something in FY ’26, ’27 is when we’d be looking at that ramp up in the capital. Obviously, if we make a decision, depending on the approvals, to start some of the work on that pit earlier instead of the stockpile material, that may come forward a little bit, but no decisions on that yet. And obviously, we also — you would have heard on the day at Cowal, the difference is the move to the OPC done on a dry lake or a wet lake, which does also impact on timing and capital.
Jon Bishop
Great. That’s very clear. Thank you very much.
Operator
There are no further questions at this time. I’ll now hand back to Mr. Jake Klein for closing remarks.
Jake Klein
Thanks, Andrew, and thanks, everyone. Just a reminder, for those of you who may want to attend and haven’t signed up yet, we will be running an investor and analyst visit to Red Lake in September around the Denver Gold Forum. You’re welcome to attend if you want to. I highly recommend it.
And then just to recap those three messages, hopefully, we’ll see some of that commentary in your analysis and reports coming through. First one, we are entering a period of lower capital intensity and higher cash generation. Secondly, a very strong record of 21 consecutive dividends, an ongoing strong focus on capital management and a reconfirmation of our investment grade credit rating. And thirdly, I don’t think this needs much emphasis, but Ernest Henry is genuinely a world-class orebody.
Thanks very much. We’re looking forward to speaking to you over the next couple of days. As usual, we want to be transparent and open, so if you have any questions, we’ve got one to go back to Dan with. But if you have any questions, please contact us and we’ll be happy to answer them. Thanks very much.
