Earnings Call Speaker Segments
Operator
operatorThank you for standing by, and welcome to the Regis Resources Limited Full Year Results. [Operator Instructions] I would now like to hand the conference over to Mr. Jim Beyer, Managing Director and CEO. Please go ahead.
Jim Beyer
executiveThanks, Sari, and welcome, everybody, to our call on the full year financial results for FY '22. Joining me is Elena Macrides, our co-Sec; Ben Goldblum, Head of Investor Relations; Tony Bevan, our Interim Chief Financial Officer; and Stuart Gula, our Chief Operating Officer. All right. So you should see on your screen 2 things, a PowerPoint presentation, which we'll step through and a phot of myself, unfortunately, for you. All right. So turning to Page -- Slide 2, please, operator. I'd just draw your attention to the cautionary statement. We do make some forward-looking comments and discuss targets later on. So I'd just draw your attention to that statement. Slide 3, thanks. Look, we've had a year with record production, as we've noted earlier, and it's great. It's been our first full year of production from Tropicana contributing to our performance as well. At the same time, we've been making a considerable investment in the future and our future production levels. overlaid with this has been a very challenging environment with the impacts of COVID and the inflationary conditions clearly having an impact on our results -- on our financial results. Our EBITDA was $336 million. That was after a $74 million write-down, giving us an EBITDA margin of about 33%. Our cash flow is still reflecting the strength, I think, of our operating business, $347 million. We ended the financial year with 30 June of cash and bullion at $231 million. And that's after getting an AISC through the full year of $1,556, giving us a margin of $756 an ounce, but also noting in there that we had $161 million in growth capital through that period as well, as I mentioned before, considerable investment in our future. That led us after a noncash post-tax adjustment of $60 million to a statutory net profit of $14 million. Now with this context, as I mentioned, of the external impacts and importantly, a couple of aspects here, the conservative nature of our balance sheet and what we see and our Board sees as a positive outlook for our operations. The Board had confidence in delivering a full year dividend of $0.02 fully franked shares. So that's a bit of a high-level summary of our financials. If we turn to Slide 4, and I know that today has a focus on our financials, but there's a couple of things I just wanted to touch on around our ESG front. Slide 4, please, operator? So the first thing is I just highlight the fact that our safety, as measured by lost time injury frequency rate, is still quite a pleasing level. I mean you're never happy until the number is 0, of course. But we do sit more than 40% below the industry average. Our diversity is quite -- very strong, I think. We have around about 23% female as a measure of diversity, which is certainly above the industry average, which is sitting a few percent below that. Looking at our environment, we had 0 noncompliances and no significant incidents. Pleasingly, I guess, and the one thing I did want to also highlight on this slide was we've approved and are underway with the construction of a 9-megawatt solar farm at Duketon. Of course, this has got 2 advantages to us. No doubt, people are pleased to see that the impacts of carbon reduction and reducing our carbon intensity over time with this. But also, importantly, this has a quite significant impact on reducing our power costs as this will be fed into the power grid that we have down at Chiton South. So a great project that will take about 12 months or so to get that online completely, but we're pleased that we've been able to get that 1 moving. So what I'd like to do at this stage now is hand over to Tony, who will talk through a little bit more of the detail of our results and background to the full year. Thanks, Tony, over to you.
Tony Hinkley
executiveThanks, Jim, and if we could turn to Slide 5, please. So this is just a highlight summary and some of the further slides will talk in more detail around the net profit and cash flow, but I'll just highlight there the increase in production and revenue. Revenue increased by about 24% over the year, and cash flow from operations also increased as well as $347 million. And I suppose that's largely as a result of the impact of the full 12 months of operations at Tropicana. Just the other point I'll make on figures on this page are the EBITDA for the current year of $336 million, that's after a $74 million noncash adjustment for NRV write-downs. So if you could just turn to Page 6, we'll go into more detail on the net profit result. So profit was obviously below expectation, and I suppose that's been impacted by 2 significant events or 2 factors. The first is the noncash write-down as an impairment, which totaled $85 million before tax, and cost increases that're particularly felt in the second half of the year with fuel and the -- I suppose, the effects that has on the broader business as well. So just in terms of the noncash write-downs and impairments totaling $85 million, $74 million of that was the write-down of net realizable value of the 4 stockpiles, and the 2 major factors contributed to this write-down. We -- when we reviewed the life of mine in the second half of the year, we pushed out the timing for when we were going to process those stockpiles. So as a result, by pushing those, the timing of those -- that processing further out, the gold price used in the NRV assessment is slightly lower because it's based on the consensus price. So that has an impact on the NRV assessment. So that was the big factor in the write-down. And also the other factor is the cost to complete have increased, so that was the other factor. So that -- as I said, that NRV write-down was $74 million. And it's a noncash adjustment, which is included in the EBITDA. I'll also just on that slide, point out the significantly increased depreciation and amortization associated with the Tropicana purchase. This obviously does have an effect on net profit, but does not impact cash or EBITDA. If we can turn to Slide 7. So the -- this is a summary of -- a waterfall of the cash flow for the year. And you can see we started the year at $269 million of cash and $1 billion on hand and finished the year with $231 million. Cash from operations of $378 million. So that's -- the operation has generated a very positive -- very healthy cash flow. And in those next 3 bars, the $219 million mine development, the $56 million exploration and McPhillamys and the $78 million of other CapEx, they're all investment in future growth. So we generated $378 million, and we spent $353 million on the future. So I think that's a very positive message. So really, that's the cash flow summary for the year. And that includes a dividend of $22 million, which is paid during the financial year. If we then turn to Slide 8. The cash and bullion balance, as I've mentioned, of $231 million. In our quarterly report, we did highlight the fact that since year-end, we have -- there have been some significant one-off payments, which have reduced this cash balance. And that related with the payment of the stamp duty on Tropicana, and also our property purchase in New South Wales. And that total -- the total of those 2 transactions was about $60 million, which has reduced the cash balance since year-end. Our net debt is $69 million as at 30 June. So that's made up of the $231 million cash and bullion on hand, less the $300 million syndicated finance facility, giving you that net debt of $69 million. That $300 million finance facility matures in -- towards the last -- in the last quarter of FY '24, and we're obviously looking at refinancing options associated with the McPhillamys development. Our hedge book, we reduced the hedge book by 100,000 ounces during the year. And so there's only -- there's 220,000 ounces remaining as of 30 June, and that will be that hedge book will be closed out in the next 2 financial years. So currently, 75% of our gold ounces sold are unhedged and exposed to the spot gold price. I'll now hand back to Jim.
Jim Beyer
executiveThanks, Tony. Okay. Well, look, if we just turn to Slide 9, there's not a lot to point out there. That's our guidance, which we've already noted earlier this financial year. Our group guidance in total, 50 -- between 450,000 and 500,000 ounces, all-in sustaining sitting between $1,525 and $1,625. Our growth capital, as noted, $145 million to $155 million, and our exploration and including McPhillamys is around $72 million. So no change on that front. If you could turn to Slide 10, please. So this is, again, something that isn't new, but it's just a good point for us to show. This is where we're heading. And when we talk about the investment that we've made this year -- or sorry, in the prior year, it's helping us to -- it's all part of our plans and our approach to target this 500,000 ounces per year by FY '25. We see that by our 2 operations, Duketon, we can -- we see -- our target there is to get that up to around 350,000. And at Tropicana, we're anticipating the target there of 150,000 is quite imminently doable. The key change coming through Tropicana this year is actually the Havana cutback. While it will continue for a pretty significant area of activity for the next year, it will start to be a significant contributor to production as we expose a lot more ore and can really start feeding that into the mill and displacing some of the lower-grade feed coming off stockpiles at the moment. So it's planned, of course, as you can see, it does involve a steady reduction in the growth capital decreasing through FY '24. And as you look out to FY '26 and beyond, it's sort of a hazy sort of bluey mixture of colors. We do look at the potential out there for McPhillamys. Although we obviously haven't included that in that growth capital from Duketon and Tropicana. But we see that there are a number of options for us to be able to get to 500 -- target of 500,000 and also to be able to certainly maintain that going forward from FY '25. If I could just turn to Slide 11, please, to wrap it up. Thank you. So what we see here is, just as a reminder, we have a strong financial platform. Tony just talked through the net debt position, and we're certainly in a position to start being able to generate more cash in the future as we move from our -- this capitalization phase that we've been in. We are generating from an operating point of view, strong cash flows, long reserve life with a production profile that does grow, as I've indicated. We do operate clearly in a Tier 1 location. We have a progressive and measured approach to ESG, and by that, means we are moving forward. But we are making appropriate -- we're not making outlandish comments or commitments. We've been steady and considered, but also we are making very strong progress, as identifying and highlighting in our earlier -- my earlier points on ESG. We are looking at our businesses to return to a more consistent plan in delivery. Although we do continue to see as you normally get with a bit of ebb and flow with movements from quarter-to-quarter. But we are getting our operations back on a more reliable basis from where we were at the end of calendar '21, which is very pleasing to see. And we don't touch on it, but I have mentioned earlier some of the very exciting exploration results we're starting to see come through from our exploration program from the last couple of years that we've been stepping up, particularly around areas such as Maverick and the like in that Rosemont trend, Rosemont Baneygo trend. Anyway, we'll pull out there. Today was about the financial results. So I'd like to hand it back now to Sari and open it up to any questions.
Operator
operator[Operator Instructions] Your first question comes from Daniel Morgan from Barrenjoey.
Daniel Morgan
analystJust on the just the stockpiles under the impairment. Could you talk about maybe what the breakeven gold price you think you need to process there? Just to help us think about if the gold price goes up or assumptions change, might these come back into the mine plan?
Jim Beyer
executiveThese are in the mine plan, Daniel. From a cash point of view, these stockpiles are actually quite valuable. The write-down was because the way that they are done from a statutory reporting point of view, those stockpiles have both -- they carry a cost, if you like, of history. And when we sat down and looked at the timing of it, and as Tony said, we've pushed some of those stockpile treatments because we've been able to reschedule things, we pushed them out in time a little bit. And we also see some increased cost to processing. From a profit point of view, they were in the red, which is why we had to take the write-down. From a cash flow point of view, those stockpiles are still highly valuable and the gold price would need to be considerably lower than what it is today for them to be not worth the price of processing. They're actually quite valuable to us because, from a cash point of view, they're basically all paid for. All they've got to cover going forward is the cost to pick it up and process it through the mill. So any gold price involved in not processing those stock piles would be pretty low. And understand they've been written down from an accounting point of view, they are still stockpiles that sit in our mine plan because they add considerable value from an NPV basis.
Daniel Morgan
analystAnd just further on that, when do they roughly sit in the mine plan? And does it relate to Moolart Well? Or is it throughout the business?
Jim Beyer
executiveIt's throughout the business. So it's varying between Moolart at the moment. It could be a couple of years out, whereas down at Duketon South, there could be certainly 4 or 5 years out.
Daniel Morgan
analystOkay. And just -- could you refresh us on Moolart Well? What is the plan on mining, processing and life there -- or life extension there?
Jim Beyer
executiveSure. Moolart, at the moment, based on our reserves, we will be moving to -- we'll be mining ore and direct feeding into the mill this year and into part of next year. And after that, we start to deal with some of those stockpiles that we've been talking about. However, we have some opportunities -- some growth opportunity there in an area called Commonwealth, which is sitting well and truly within the isopach of distance from the Moolart mill. And we haven't -- we haven't finalized our reserves on that, but they certainly -- we've been out there drilling over the last couple of months and the results there are particularly encouraging. So we're anticipating that as those come through that, that life at Moolart will gain something from that. And we've got a few other things that are very interesting there, but we're not quite ready to break cover on. So as a minimum, we see probably, including the stockpiles that we've got there, I think Moolart will be around for at least another 3 or 4 years. So there's a couple of years of stockpile treatment. But if we manage to deliver on the plan that we're following, we'll be able to feed in some good material coming from deposits such as Commonwealth, which will add another -- well, as many as we find it will add, I guess.
Daniel Morgan
analystAnd then just switching to Tropicana. There's an asset review called full asset potential. What does that involve? How are you -- are you providing input into it? And what do you expect the timing will be on that? I know you said first half of this fiscal year, but just wondering if it's later or...
Jim Beyer
executiveYes. So the full asset potential is something that Alberta has got running right through our Anglo Gold. And it's actually quite similar to a program that was running in Newmont back when Goldberg took over. So that was several years ago now. And it was -- it basically looks at the business, looks at each site, looks at their bottlenecks, looks at opportunities for how has the place been run? I guess it's one of these activities where long-held sacred cows might get questioned, for example. There's also an examination of -- and looking at how the mine -- is the mine being run at an optimum point? So it's -- I would describe it as a great opportunity where the can gets kicked over and everybody has a look and see whether it's actually -- there's a more valuable way of running it. It's a well-structured process. It's buying the group that are partnered with that. Our role is the same as management's role. It's really a senior management's role. It's an oversight to see what happens. The team, there is a very well-structured process that goes -- that basically breaks down cost mapping exercises and things like that. So we watch and provide a bit of input and maybe suggest areas to look at, but it's a pretty thorough process on its own. It also looks at other elements of the cost to see whether there is opportunities to -- for the more general cost reduction of, do we need to use as many posted notes as we do? Okay, it's obviously a lot more serious than that, but -- so it's a really quite -- well-structured approach that comes in from both ways. How is the business run? Has it got the right mine plans? And are there -- where are the cost-out opportunities to make the business more efficient just running with the existing plan? Time-wise, it's underway at the moment. We won't -- nothing's changed from the timing expectations that we've given before. So I think there's an update due in the next couple of weeks, I think. Don't hold me to that. I can't remember exactly what that date is. Actually, I think it might be after the Denver Gold Show. And there's a program that where there will be some quick hits, but there's also -- anything that does get worked on will probably take several months to follow through. But we're particularly pleased that it's being done early in the cycle, running right across Anglo. So -- and the feedback from other operations that has been done already has been very positive. So we look forward to talking about the results in due course.
Operator
operatorYour next question comes from Andrew Bowler from Macquarie.
Andrew Bowler
analystHad a couple of mine to add. Just after a bit more color on how you're thinking about divvies over the next couple of years, just obviously given the potential for McPhillamys spend to start in the next little while?
Jim Beyer
executiveYes. Look, it's good -- thanks, Andrew. Good question. I think the idea that the dividend was paid, and obviously, there's a fair bit of discussion about it, but we -- it's as much a recognition of how confident we feel about all the work that we've been doing, not just in the last year, but the last couple of years really is starting to set the business as how that's looking. The -- what we will do with dividends, we will consider at the time as we were asked on a number of occasions, do we have a policy, and we don't. But we also recognize that the intention of a business is to make profit and return a combination of that profit to the -- to shareholders, while retaining some of it to continue to build the business in the future, which, of course, is so critical for mining resource companies. I think the payment -- Regis has got a great history of paying a dividend. We're certainly well and truly well over $0.5 billion in dividends being paid since we kicked it off. We will look at the future as to a combination of both the profitability of the business over the next 12 months and also what the demand might be for capital around McPhillamys and its timing. And also how we would -- whether we would decide to take an approach to try and fund that all out -- we'll look to fund that all out of cash flow or whether we do it with a combination of a bit of cash and a bit of debt, which is probably more the way we're thinking at the moment. So it's not a flash in the pan. It wasn't a decision that was made quickly. It was a recognition that both we're in a position where we could pay, but also where we were confident with the way the company was going to be performing over the coming 12 months in the future.
Operator
operatorYour next question comes from Peter O'Connor from Shaw and Partners.
Peter O'Connor
analystCongrats on the results. Jim, firstly, back on the dividend. Do you have a must-pay view at the board level?
Jim Beyer
executiveNo, because that would be a policy. No, but we...
Peter O'Connor
analystLet me put another way, do you think that shareholders would expect you to continue because of your continuity of dividends? And is that something that's front and center of discussion when you have those deliberations?
Jim Beyer
executiveI think the payment of dividend is front and center of the conversation. I mean it's a reason to be, right. It's part why does the business -- there needs to be a combination of growth and return. But ultimately, you've got to look at your return. We've done some -- it's certainly -- we've had a great record of that in the past. It's pretty safe to say that over the last couple of years, it's been a little bit harder for us, but that's also in part because we've been dealing with some of the historic hedges, which have had an impact on our ability to pay dividends at the levels that they were before. But I think the fact that we've done it and the fact that we've -- it hasn't been a great -- from a pure statutory accounting point of view, it's been a challenging year, but we still feel that it's appropriate to be paying dividends. As I said, a combination of where we currently sit and how we think we're going to be in the future. So the Board certainly takes a very strong consideration as to our ability to pay dividends, certainly in the full year. Whether you're talking to interims, I guess, is maybe a different question. But certainly every full year at least. And it will continue to do that. But if it means putting balance sheet at risk, then I think -- just for the h*** of paying a dividend and effectively, if you're saying, will we pay a dividend if we didn't think we could afford it or the business was positioned right, I think -- I don't think we'd be pressuring ourselves to do it just for the -- just to continue to feel good.
Peter O'Connor
analystAnd back to the impairment. You make a really good point to sit it down about the -- its noncash impairment and these stockpiles are actually very valuable. Could you just put some numbers around that. So you took it, you got to pick it up, a couple of bucks a tonne. You've got to process it $20 a tonne. Is that kind of what I'm looking at from a cash perspective when I process that material?
Jim Beyer
executivePretty much. Pretty much.
Peter O'Connor
analystSo from competitor gold price at AUD 2,500, AUD 2,600, I've got a pretty solid cash margin on those ounces despite the fact from an accounting perspective, they may be more marginal?
Jim Beyer
executiveWell, as you say, it's a couple of bucks to pick it up. Processing cost per tonne are probably -- it's the high 20s. So you got to put a little bit on for tailings, the cost to build -- putting a tailing -- the tailings dams, we always estimate a $0.50 a tonne. You've obviously got to put it somewhere. So this is -- it's pretty -- it's low cost up. And some of the stockpiles are actually quite low grade. But I've always said, we put -- we just make -- some stockpiles are very low grade, and we -- specifically, from an accounting point of view, we don't put any -- they don't carry any value because they're the ones that you just -- you know you're going to get caught up with. These stockpiles where we took the write-downs on, they were sort of middling, I don't know, when you get a grade, I guess, the grade probably be sitting about 0.4 grams, something like that? That sort of grade. So they're not -- if they were ripping tonnes, we'd put the d*** thing through the mill already. so it's all part of the classic get in line category of grade management. So yes, but it's still -- they will still make reasonable cash.
Peter O'Connor
analystAnd Jim, there the recovery declines with grade, is that how we should think about it as well when you put that 0.4 grams through mill or through recovery?
Jim Beyer
executiveYes. We adjust -- as you quite rightly point out, recovery is usually related as much to -- there's always a bit of gold that goes out in tails that you just can't get, and therefore, your recoveries drop as the grade goes lower. Yes, it's well noted, and that's all taken into account.
Peter O'Connor
analystOkay. And I'm just intrigued about the use of consensus price deck. I'm sure your auditors must have had some flexibility, what you presented. Why wouldn't you present a forward curve?
Jim Beyer
executiveYes, it's a good question. And that is, it does become a point of discussion. I guess the more conventional way to run it is with a consensus price deck. If you -- arguably, if you're going to use a forward price deck, you could use that if you actually have locked everything in, which we haven't. So we use the -- we use data from the consensus price deck, which is pretty conventional.
Peter O'Connor
analystJust philosophically, using data from a bunch of muppets like us instead of a forward curve, which is a much deeper liquid market. Seems odd. My next question is corporate and admin costs are up about $5 million. Is that just Tropicana additional costs? Or what's that?
Jim Beyer
executiveSorry, what was that last question? I was still trying to come to terms with you describing yourself as a muppet, Pete.
Peter O'Connor
analystSpeaking in the third person, not me. Corporate and admin costs, up $5 million year-on-year. Is that Tropicana and just the additional work with that? Or is that the going rate going forward?
Jim Beyer
executiveIt's a little bit -- there was a little bit of spillover. A large bit of cash that had to be paid out for some fees for the Tropicana deal, which is sort of a nonrecurring piece that pushed it up a bit. I think that was about $6 million or $7 million sitting in there.
Peter O'Connor
analystSo what should we think about long term?
Jim Beyer
executiveWell, what we had...
Peter O'Connor
analyst$20 million, that $20 million.
Jim Beyer
executiveA little bit more than that. From a total corporate maybe $20 million, $24 million.
Peter O'Connor
analystOkay. You had another impairment, a noncurrent asset impairment of $11 million. It was below the EBITDA line. What does that relate to?
Jim Beyer
executiveYes. So the stockpiles are actually not impairments. They're write-downs. Having just spent the last 2 weeks discussing this in some reasonable detail, as you can imagine, with the auditors. They do get technical on the titles. So the write-downs were on the stockpiles and the majority of that was noncurrent, meaning that it was in the future -- expected to be in the future. That impairment was related to -- it was about $10 million, I think. $10 million or $11 million. It related to some exploration ground that was dropped that had some value that we had to impair and take that in full. Impairments are taken off in this below-the-line terminology, whereas write-downs are incorporated, taken off EBITDA, even if they're noncurrent.
Peter O'Connor
analystGot it. And, Jim, on D&A, clearly, the big step up, we know it's Tropicana. How you review your mineral reserve and resource position -- or what Anglo does as part of the JV every year. So when do we expect the next meaningful review of that? And when could we expect that unit depreciation charge to step down as you extend the reserve basis? Will a drip fee do in it so it will never really change? Or do we get a large step at some point [indiscernible] because of that?
Jim Beyer
executiveYes, good question. Look, I don't think we go -- I mean, we'll see steps here. I think, like last year in the resources, I think the -- sorry, in the reserves at Trop. It went backwards a little bit, but it did include the first reserve statement for the Tropicana underground. And I think what we're going to see -- and we're understanding the mine plan and the timing. I think it will be probably more likely to be steps than a little bit dribbling in every year. Although we've just got to wait and see how that plays out just based on the -- I think the extension of reserves, for example, [indiscernible] likely to maybe be a reasonably steady rolling addition because it's got well-established development, and it's an extension of geology. Whereas when we look over at Tropicana, there's areas there that are basically, historically, have had no drill holes in. Now we're putting them in. We're starting to -- as we were expecting, we were finding mineralization. They've got to plan and put the development in to make sure they can access that, which is -- it's a bonus that it's being found, which is what we think is great. It just -- it's not quite as smooth in its ability to sort of roll forward. So I think that might come in, in spits and spurts. And then the other area that they're looking at over there is the Havana underground, which I think -- well, there's nothing in the plans for that, no reserves there at the moment for the underground, but we've already got the -- I can't remember what it's called now, the Link Drive isn't it? The link drive that's been commenced where there's a drive that heads out there. And we'll be doing some resource and drilling there for the next phase of a feasibility study on that area. So I think there are some things that are going to roll quite steadily, and the others will come in steps and not quite so smooth while they get into the rhythm.
Peter O'Connor
analystJim, the last question, Page 10, the growth outlook, plus 500,000 ounces. You talked about McPhillamys and other internal sources. Is that other internal -- is that Havana? Is that the underground? Is it Trop? And is that middle ground that you talked about at the quarterly between in Duketon the area that you're looking at, at the moment? Are they the type of opportunities you're thinking about?
Jim Beyer
executiveYes, yes. Certainly, we see opportunities in -- like Garden Well Main is probably one of the -- from an underground point of view, one of the more exciting areas we see significant potential in. We're just working through the process to finalizing the details of that big exploration -- or not big, but an exploration drive we want to put out there. We see some rolling additions for Rosemont underground as well beyond the existing reserve life. We also see, as I mentioned earlier, the deposits like Commonwealth. Ben Hur, we see extensions of it. They've got potential there. And then a little bit further afield, we've got underground potential at Gloster, which is some great intercepts, but complex geology that we're trying to work on as well. So we certainly see the potential for -- getting to the 350,000 at Duketon is really squeezing some of our assets just a little bit harder, and we're a bit wary of being too quick to run into that. But we also see additional production coming from new production sources. And like Garden Well Main, like Commonwealth and like a couple of other areas that we're just working our way through that we'll let people know about when we're a bit more clear on their contribution.
Operator
operatorYour next question comes from [ Alexander Papayowanu ] from Citi.
Unknown Analyst
analystJust one question from me. One of your peers has reported easing input costs since their initial FY '23 guidance in July. Have you noticed any easing at your cost of your operations?
Jim Beyer
executiveWell, yes, look, probably the most obvious one is fuel. Fuel was actually quite significant. I mean it was amazingly -- FY '22 was like the year of 2 halves. The fuel -- the average fuel price that we paid in the first half of last year was probably mid-80s. And then the fuel price that we paid in the second half of the year was probably $1.20 or something like that. If you look at our sensitivity to fuel, in rough terms a $0.10 movement in fuel price is worth about $15 an ounce, something like that. We have certainly -- in our all-in sustaining cost guidance, we made -- we were assuming that the fuel price as it was back in June would stay that way for probably at least a quarter and then some easing back to $1.40. So I think our average -- the average fuel price we use for AISC was about $1.475 a liter. So has it moved? Fuel has actually softened a little bit, I think, in the last month, which is nice. Not enough for us to charge out and restate our guidance at this point in time. We'll probably wait and see what happens. Other costs, less so. Fuel is clearly the one that has the biggest impact representing, I think, around about 20%, 25% of our costs. So that is a single point that we -- that is probably the most big leverage, all the rest. And that's direct. I mean fuel then has other flow-ons to everything from how much it costs to move things to site to how much it cost to run plants and all those sorts of things. So that's -- we have seen a little bit of movement, but nothing at the moment that's caused us to go back to our guidance and say we're nervous about [indiscernible] expressed.

operator[Operator Instructions] Your next question comes from Patrick Collier from Credit Suisse.
Patrick Collier
analystTwo for me, please. Firstly, on the stockpile write-down, can you give any insight on what the split was between the gold price assumption change versus the processing costs, I imagine those are the 2 main factors?
Jim Beyer
executiveNo, we haven't got that detail to go into. I think -- I mean, I don't even know what it is off the top of my head, but it was -- there was a reason -- I mean the gold price was -- that we were seeing, certainly for the DSO all. Our stockpiles was a couple -- at least a couple of hundred dollars lower because it was pushed further out in time. And the operating costs were -- yes, I don't know. I'd be guessing if it was half and half. But we haven't got the breakdown, and it's probably, I think, getting into a little bit too much detail. But both of them were significant contributors to the outcome.
Patrick Collier
analystOkay, that makes sense. That's significant. And then just looking at the refinancing and looking at funding McPhillamys, are you able to comment on what level of debt you'd be comfortable with? And just any metrics that you're using to assess that when the time comes?
Jim Beyer
executiveNo, we haven't. Well, there's a couple of things that we've actually got to be thinking about. One is the -- obviously, what's the capital cost going to be, and we've done quite a lot of work on that, as you can imagine. But -- and there are, certainly in the last 6 to 12 months, have been significant pressures on the cost of building anything, both in terms of the availability of people and the raw inputs. Although we do note that things like steel and some of the others have dropped in price a little bit, which is helpful. What we do need to consider when we're -- with our funding is we'll -- as Tony said, we have about $300 million worth of debt sitting on the balance sheet that's due for the bullet in mid -- 2 years -- a bit over 2 years' time -- a bit less than 2 years' time, I should say. And that, no doubt, would form part of how we would restructure our debt around that and incorporating McPhillamys. We haven't set ourselves any metrics and the likes of debt ratios and the like. We're just starting to turn our mind to how that looks. Obviously, also wanting to understand what our cash flow generating is as we get closer to the time will be an important one as well. When we bought Tropicana, one of the things that we liked about Tropicana was once it got through the -- this high pre-strip phase at Havana, which was last year and continues this year and starts to drop off from next year, it then moves into a much more significant cash generating phase. For the right gold price, if we wanted to, we could potentially fund it out of cash flow because we'll also -- so we'll -- there's a lot of levers and a lot of moving parts in that at the moment, Patrick. So I can't -- that's probably the best I can give you on context.
Operator
operatorWe have a follow-up question from Peter O'Connor from Shaw and Partners.
Peter O'Connor
analystJim, just with that last question in mind and looking at Slide 7. Just trying to think about the cash flow generation going forward, as you're probably doing every board meeting. Mine development, exploration, McPhillamys and other CapEx, could you just walk us through how those numbers will look? I know you've given us guidance this for FY '23, but more like a '24, '25. You talked about the drop off at Tropicana and the drop off at Duketon. Is a big step down in mine development?
Jim Beyer
executiveSo I'll give you some context around -- and using the guidance that we've already provided. We're not in the position or desire to continue to expand on that at the moment. But you can see what our cash flows are going to be roughly looking like over the -- this coming 12 months. That's a whole idea of AISC and growth capital and the other key elements that we give there. If I look a little bit further out, and I don't think they certainly made no secret of the fact that at Tropicana -- Tropicana's total material movement last year was a little bit -- was lower than we would -- we're all planning on, and that was some significant impacts on there from COVID-related labor availability. I think the site's back running on its plan now, which is great to see. We'll see total material movement levels, I think roughly the same this year as last year. And then after that...
Peter O'Connor
analystWhat's that number, Tim, how much TMM?
Jim Beyer
executiveI think it's about $8 million or $9 million -- actually, that might be 30%, I think, at 30%. So it's going to be a similar level. And we outlined that in when -- if you look at the -- if you look at our physicals in our quarterly reports, you can see how it's been traveling. So it'd probably continue along those lines for the next 12 months, and then it starts to drop down by at least 10% or 15% depending on their performance this year. And then as you do with open pits, it starts to drop away. And then any of the real growth work then just sits in underground development, which is more routine in nature as we just continue to roll down plunge. At Duketon, it's -- well, it -- as these things are -- if you look at the plan at the moment, for example, at Moolart, at Duketon North the total material movement -- I mean we're moving almost half as much material -- a little bit more than half as much material this year at Duketon as we did last year. So that's obviously quite a reasonable drop in materials, but that's on the basis that we don't bring in any more new open pits. If Commonwealth comes in, then we'll see some pickup that -- you got to do a little bit of pre-mining before you get into that. So that -- but that's not part of our guidance at the moment. So as they come in, we'll provide an update and if that has an impact on -- give -- we'll give an indication of what the impacts of that are at the time. So the short -- in the near term, Tropicana levels of activity on site are probably staying pretty much where they were last year -- at least for this year, and then they drop off. And Duketon has already started its drop off because of a lot of the capital work from last year, we see. As I said, the physicals drop off. Now the -- unless we find and incorporate into our plans new open pits, then that will continue to drop off. But obviously, what we'd like to do is to not have a drop off to nothing because that's the least desirable outcome. So we're expecting that we see some easing this year, but not a complete drop to 0 in the following years. It will stay at the levels. And depending on how successful we find more material, it might lift a little bit, but we don't have a clear picture on that to give you.
Peter O'Connor
analystThere's another way to think about it, Jim, that over the next year or 2, your capital total will be close to depreciation. But post that, it drops away quite sharply?
Jim Beyer
executiveWhat are you saying? So the capital...
Peter O'Connor
analystDepreciation is about $300 million and your capital spend last year was about $300 million. It sounds like this year is going to be about the same, $300 million depreciation versus $300 million capital, is similar. And beyond that when you get to things you just talked about coming back, you'll be spending less than you're appreciating so you get that tax benefit in the P&L and you see cash flow benefit as well?
Jim Beyer
executiveYes. So I mean for the current year, you might be right. But beyond that, it's too complicated -- well, it's not too complicated. It's just that we don't give guidance that far out.
Operator
operatorThere are no further questions at this time. I'll now hand back to Mr. Beyer for closing remarks. Please go ahead.
Jim Beyer
executiveAll right. Thanks, everybody. We appreciate you joining. We realize it's a very busy time. As always, if anybody has got any follow-up questions, please touch base with Ben, and we'll do what we can to help you from there. We do appreciate everyone coming on the time and especially the questions, that helps to expand and elaborate. So I hope everybody has a good day, and we'll hopefully catch up with people soon. Bye.
