Earnings Call Transcript · May 15, 2026
Highlights from the call
In Q3 of fiscal year 2026, Alkane Resources Ltd reported record financial and operational results, with revenue exceeding AUD 274 million and a net profit after tax of AUD 93 million. The company is on track to meet its annual production guidance of 155,000 to 168,000 gold equivalent ounces, supported by strong operational performance across its mines. Management maintained a disciplined approach to costs, with all-in sustaining costs projected between AUD 2,600 to AUD 2,900 per ounce, while also signaling aggressive growth through exploration and potential M&A activities.
Main topics
- Record Production and Financial Performance: Alkane achieved a record production of 45,800 gold equivalent ounces in Q3, a 5% increase from Q2. The company generated AUD 189 million in operating cash flow, which is over 40% higher than the previous quarter, highlighting strong operational efficiency. Management stated, "We've just delivered another record-breaking quarter across the board, and this is both operationally and financially."
- Strong Cash Position: Alkane ended the quarter with AUD 374 million in cash, bullion, and liquid investments, which positions the company well for future growth initiatives. CFO James Carter noted, "We have access to up to $520 million of liquidity through the cash bullion listed investments."
- Cost Management Discipline: The company's all-in sustaining costs are projected to be at the higher end of guidance at AUD 2,600 to AUD 2,900 per ounce. This reflects a commitment to maintaining margins despite rising operational costs. CEO Nicolas Earner emphasized, "We retain discipline on the cost front."
- Exploration and Growth Strategy: Alkane is investing approximately AUD 80 million in growth capital and exploration to expand resources and drive production growth. The management highlighted ongoing exploration activities across all sites, aiming to extend mine life and increase production levels. Earner stated, "We want to extend our mine life. We want to accelerate production growth at all 3 mines."
- Integration of Mandalay Resources: The merger with Mandalay Resources is contributing positively to Alkane's operational results, with the Q3 results reflecting 8 months of production from the Costerfield and Bjorkdal mines. This integration is expected to enhance overall production capabilities moving forward.
Key metrics mentioned

I will now hand the call over to Nick Earner. Please go ahead, Nick.
Nicolas Earner
ExecutivesThanks, everyone, for joining us today. Let's jump right into Slide 4, which tells a pretty clear story. We've just delivered another record-breaking quarter across the board, and this is both operationally and financially. All 3 of our mines are operating really well. On a consolidated basis, we produced a record 45,800 gold equivalent ounces in the quarter, is about 5% higher than in quarter 2. For the first 9 months of our fiscal year, we produced 120,000 gold equivalent ounces. This is well on our way to meeting our full year guidance of 155,000 to 168,000 gold equivalent ounces, remembering, as Nat said, that this doesn't include July's production from Costerfield and Bjorkdal. Given the strong prices for gold and antimony and our robust production results, our mines generated AUD 189 million in operating cash flow in the quarter. This is a bit over 40% higher than in quarter 2. At quarter end, we had AUD 374 million in cash, bullion and liquid investments on hand. We continue to build our financial position clearly to aggressively grow the company through both exploration and capital at each of our mines and advance the Boda-Kaiser copper-gold Porphyry project. And as I've discussed previously, we're simultaneously seeking M&A to opportunistically grow the company. Another accomplishment I'd like to point out, which we're pretty proud of, which occurred subsequent to quarter end, Alkane was included in the S&P ASX 200 Index on April 22. We expect this to, in time, result in a further increase in stock liquidity and potentially reduce volatility as a greater number of investment funds can now own Alkane in their respective portfolios. Now let me move on to Slide 5. On a consolidated basis in Q3, Alkane mined more than 620,000 ounces of ore at an average gold grade of 2.33 grams per tonne and an average antimony grade of 1.12%. Recoveries of 91.4% gold and 85.9% antimony remained fairly consistent quarter-over-quarter. As a result, our mines produced nearly 46,000 gold equivalent ounces, consisting of nearly 45,000 ounces of gold and 377 tonnes of antimony, which again is a record for the company. I'll get into specifics on each mine shortly. Needless to say, all of our mines are operating well, and we remain on track to meet fiscal 2026 guidance. Moving on to Slide 6 at Tomingley. In quarter 3, we produced 315,000 tonnes of ore, which is just a touch less, 1% less than quarter 2 and an average recovery rate of 90.1% with an average grade of 2.4 grams per tonne of gold. This result in production of 21,652 ounces of gold, which is a touch lower than in Q2. Processing continues to perform well and milling is exceeding plan. Now this is primarily as a result of an insertion of a mobile crusher to pre-crush material prior to entering the processing circuit. This pre-crushing material, which is we've tried different sizes prior to entering the circuit continues, and it's seen an increase in milling rates to about 1.3 million tonnes per annum. Further optimization to balance our throughput and the cost that occurs in this mobile crusher continues. The primary source of ore continues to be from the Roswell deposit. Underground ore was slightly below what we would have liked, primarily due to stope performance issues on several stopes that required rework, but this was offset slightly by higher development ore tonnages. Capital expenditure during the quarter was allocated primarily for our Newell Highway realignment project. Construction of this is expected to complete in Q2 fiscal 2027, so the end of this calendar year 2026. By accessing the high-grade San Antonio deposits by 2 new open cuts, this high-return project will accelerate Tomingley's growth and further optimize our cost profile. All-in sustaining costs at Tomingley in quarter 3 were AUD 2,444 per ounce, about 10% higher than we had in Q2. The higher costs were a result of higher processing costs, which includes the cost of the rental crusher, which, as I said before, this is a high-return initiative that's continued into Q4 and expected to continue going forward. Overall, Tomingley generated AUD 54 million in the third quarter. Moving on to Slide 7. At Costerfield, our gold-antimony mine, we processed 36,000 tonnes of ore. In Q3, gold grades were 10.2 grams per tonne, in line with Q2 and antimony grades 1.2%, which is about 1/3 higher than in Q2. Gold and antimony recovery rates were 93.6% and 85.9%, respectively, matching the previous quarter. The mine produced 10,584 ounces of gold, which is similar to Q2 and 377 tonnes of antimony, which is 41% more than Q2. Now I want to stress that antimony grades can be variable throughout the mine and were higher than typically we're seeing in the ore body areas that we're in, in Q3. Overall, we remain in our mining plan and our mining guidance for Costerfield. Costerfield delivered steady-state operational performance during the quarter, with all mining and milling rates exceeded our planned rates. We've had strong mining performance in terms of tonnes mined for the quarter and our extraction from different areas complied reasonably well with forecast mining advance in each area per month. We do, of course, continue to work on our continuous improvement programs. For us at Costerfield, this is a bit of drill and blast optimization, capital development optimization. We continue to work on operator training and our transition to emulsion explosives to improve recovery and reduce dilution continues. Processing, we focus on blending control to maximize throughput, recoveries and produce metal. We also here had successful trials during the quarter with respect to pre-crushing ore feed as well and screening lower-grade ore stockpiles to further improve throughput, crusher downtime and blend control. Work continues here to prioritize that operational efficiency. All-in sustaining costs at Costerfield in Q3 were AUD 2,521 per ounce. This is 17% higher than Q2. This is primarily a result of a one-off AUD 4 million inventory adjustment of the run-of-mine stockpile following the introduction of a new inventory model to match that used at Tomingley. As a result of all of this, Costerfield generated a record AUD 80 million in cash flow. This is a significant increase compared to the AUD 30 million we had in Q2. Moving on to Slide 8. In Q3 at Bjorkdal, we processed more than 320,000 tonnes of ore at an average grade of 1.5 grams per tonne and an average recovery rate of 90.4%. Building on this consistent operation, Bjorkdal produced 12,433 ounces of gold, which is up nearly 25% compared to the previous quarter. In general, we allocated resources to capital development activities in preference to operating development. Mine grade was in line with planned grades, and we had a slightly higher contribution from below the marble mining area, which traditionally has been a slightly high-grade area for us rather than above the Marble unit. Mill throughput decreased slightly, while recoveries improved compared to the previous quarter, albeit not really much more than we would expect in line with increased head grade. Also during this quarter, of interest, we did a trial of processing a parcel of off-site ore from a small mine to the west of Bjorkdal, and this was pretty successful. The goal with this program is to evaluate the option and possibility of sourcing off-site ore to increase production and lower cost at Bjorkdal. Through this trial, we've got an understanding, hey, this ore, it works. It's successfully into the plant, fed into the plant. It's got great recoveries. And so further studies of this negotiations, what permitting things needed are underway to understand how we can continue this program. During the quarter, there was continued underground capital development success. We achieved more than 1,100 meters. This is in line with the previous quarter. We got 1,200 meters, and we're above plans both for the quarter and year-to-date. Also, capital works on a series of lifts to the tailings dam facility have commenced. We started this once the area there thawed post winter. And additionally, the development of the [ Newlands ] open pit, a small open pit right next to the long-term Bjorkdal pit that closed many years ago and an upgrade of the equipment fleet has also continued in quarter 3. So the higher production allowed all-in sustaining costs in Q3 to be AUD 3,699 per ounce, about 10% lower than in Q2. With this improved production, operating cash flow from Bjorkdal was AUD 55 million or over 50% more than the second quarter. One of our key things is to drive organic growth by increased mineral resources, and I'm going to talk you through the exploration program across our portfolio. So let me start by moving on to Slide 9, Tomingley. At Tomingley, one of the interesting things that we did in the quarter was testing a seismic reflector feature quite deep beneath the Roswell deposit, which is bullet point #4 on your map there and near-mine prospects such as El Paso, which is bullet point #5. Now at Roswell, this deep drilling intersected gold arsenic-enriched hydrothermal breccias and veining right where we expected it in the seismic reflector. This is 400 meters below the current resources. So we've got a fair bit of further drilling plan to test where this structure intersects both the andesite and Monzodiorite units. Both of these are favorable host at Roswell and both of them extend down at depth. So a pretty interesting area for us to see whether this is an area that has fluids that feeds gold up on into Roswell. At Roswell -- I mean, sorry, at El Paso, we had 8 drill holes completed, and this resulted in us reinterpreting the geological model, allowing us to better understand the geological structure of El Paso, which we don't really fully understand. A drilling program to test the new model is planned. Meanwhile, underground drilling at Roswell itself in the quarter focused on improving confidence in the inferred resource. We got some great results like 5.9 meters at 31 grams per tonne of gold, which includes 2.1 meters at 78.4 grams per tonne of gold, got a different one of 17.4 meters grading 4.3 grams per tonne, which includes 2.5 at 21.1. These are all very typical of what we see at Roswell. Additional underground drilling has commenced to keep and accelerate this infill drilling program. So moving on to Slide 10 at Costerfield. We invested just under AUD 7 million or AUD 6.6 million in Q3 to work to expand the resources. As you can see in points 1 and 2 on the map on the slide, True Blue drilling continued. We were well advanced this in Q2, and we included step-out testing of surface geochemical anomalies. Targets around the existing workings, which these targets will be incorporated -- our results will be incorporated in the plan in the coming years into FY '27, including Kendall, bullet point 3; Brunswick South, bullet point 4 on the slide. At Kendall, 25 individual veins have now been identified and modeled. These are immediately above the currently mined Youle and Shepherd ore bodies, and these surround the historically mined from many decades ago Costerfield deposit. So we looked at extension drilling in that area, and this gave us pretty strong results, including amazing results like 1.94 meters grading, 132 grams per tonne of gold, so over 4 ounces of gold per tonne and 19.8% antimony, very high-grade antimony and 2.3 meters grading 267.5 grams per tonne over 8 ounces per tonne of gold and 5.6% antimony. These are clearly ultra-high grade and they're similar to mineralization at the nearby Fosterville mine, and these present one of our most exciting prospects. I would not want you to think that I'm saying that we have a massive tonnage here, but they're certainly very, very high grade. At Brunswick, we conducted infill and extension drilling programs with additional drill rigs mobilized to accelerate that program. And up at bullet point 6, you can see on the screen, we're also testing for potential the Sunday Creek, the Southern Cross style mineralization just below Costerfield's historic mines. So let's move on to Slide 7 (sic) [ Slide 11 ] . At Bjorkdal, drilling expenditures were just under AUD 3 million during the quarter as 3 exploration targets were progressed. Drilling at North Zone, that's bullet point 1. This moved from growing to infill, while the Eastern extension program targeted the continued depth and the eastward extension of the main and central zones. This is bullet point 2. And further to the Northeast, most interestingly, at Storheden, this growth drilling also continued as did to the East at Norrberget during the quarter. At Bjorkdal, we continue to explore for narrow high-grade veins, which we've shown that we can mine these efficiently. Let's move to Slide 12. The Northern Molong Porphyry project, the entirety of which is shown on the map on this slide, is a highly prospective gold corridor. This project also encompasses our Boda-Kaiser Copper-Gold project, which is in the bottom right of the picture that you're looking at. Exploration on this project for the quarter included our continued inversion and interpretation of the Mobile Magneto-Telluric or MMT survey data that was flown in November. Across this drilling for a total of 4,000 meters that commenced through December was completed, and we're interpreting this, and we expect to report them in the coming months. Now other low-cost activities to advance the development of Boda-Kaiser gold-copper project in the quarter included the continuation of our environmental baseline studies. We did stakeholder consultations, property negotiation, site selection and infrastructure. These are low-cost but high-impact activities. So we think that this keeps us well on the path towards a project approval application in late 2027, calendar '27 or early 2028. We have here the goal of receiving approval to then go on and make an investment decision in late 2029. So as you can see, there's a tremendous amount of exploration work going on at each of our projects, all with the goal of expanding resources and driving for new discoveries to increase the mine life, therefore, increase production levels and contain and potentially lower the costs. And with that, I'll now hand the call over to you, Jim, to provide a review of our financial performance.
James Carter
ExecutivesThanks, Nick, and hello, everyone, who's joined us on the call wherever you are today. So on Slide 13. So I'm going to start with an overview of the key financial highlights for our third quarter of our financial year 2026. And so I'll be focusing on really just this financial year as the results of the previous year don't include the former Mandalay operations. So group revenue for the quarter, that was a record just over $274 million on sales of about 42,500 ounces of gold and 280 tonnes of antimony at average realized gold price of just over AUD 6,300 per ounce and an average antimony price of about AUD 34,400 per tonne. During the quarter, we also delivered about 8,700 ounces of into our gold hedge book. That's at an average price of just around AUD 2,855 per ounce. And we've got about 5 quarters remaining of hedge deliveries through to June 2027, which is just a very small percentage of our overall forecast production and revenue. All-in sustaining costs on a consolidated basis were just over AUD 2,900 per ounce on a gold equivalent produced basis, a little bit higher than Q2. A little bit of impact there from the impact that we're seeing across the industry with diesel fuel, not so much of an issue for us as Alkane, plus just a little bit of more planned sustaining capital around underground capital development and some equipment purchases, which is sort of what we are forecasting to do. EBITDA in the March quarter, that was a record AUD 161 million, higher than the quarter previously. And for the 9 months -- for the 9 months so far this year, we've generated AUD 334 million of EBITDA, and that's an EBITDA margin of just under 50%. Net profit after tax for the March quarter, another record $93 million after tax, $0.0681 per share. And on a year-to-date basis, our net profit after tax is just under AUD 158 million or $0.1244 per share. Sustaining capital during the quarter, $24 million, largest programs, around $7 million for underground capital development at Bjorkdal, $9 million for ongoing equipment replacements at Tomingley and Bjorkdal as well. Just reminding everyone that across our 3 operations, we are -- we do own and operate all our own equipment because that works for us best efficiently and economically. Growth capital was $10 million for the quarter, and most of that's invested at our Tomingley operation in our new highway realignment, which is for the eventual mining of the San Antonio open pit in 2027. And exploration across the group in the quarter was $13 million, and Nick sort of spoke about that across our operations and our Boda-Kaiser project. So I'll turn to Slide 14 now, and we've got the cash waterfall here. So in the third quarter, cash flow from our 3 operations was a record $189 million, 42% higher than the second quarter. Corporate and other expenses sort of in that bucket of $20 million of cash outflows. We've got corporate and technical support costs, that includes about $3 million on our Boda project and some other regional exploration, $6 million for the Lupin project in Canada that we're rehabilitating and closing down, $5 million for a net repayment of equipment lease finance. And we also received $4 million during the quarter from a noncore divestment of the La Quebrada project in Chile. So after sustaining capital expenditures, growth, exploration, taxes, corporate, we ended the quarter with $328 million of cash. So net about $110 million cash growth over that quarter. So at the end of the quarter, we've got a really strong, robust financial position. We have access to up to $520 million of liquidity through the cash bullion listed investments. And we also finalized a new $110 million revolving credit facility and $40 million contingent instrument facility during the quarter. So yes, records around, a very strong quarter financially. And yes, on the back across the industry having a very good strong gold price environment. But I think it's important for us to highlight that, yes, we all have that benefit and those tailwinds. But on the ASX, when we compare, we have industry-leading margins during the March quarter as well. I think maybe on a clear cash generation per ounce sold during the quarter, I think maybe second place out of all the industry producers. So more than just a strong gold price, but we're priding ourselves on taking advantage of that through strong efficient operations, trying to keep an eye on costs as well. So that gives us in a great position to help internally fund our own organic growth projects and really position ourselves for anything that might happen opportunistically as well. And I think at that stage, I'll turn the call back to you, Nick.
Nicolas Earner
ExecutivesGreat. Thanks, Jim. Let's move on to Slide 15. Let me focus on our outlook. We want to build on this momentum that we've achieved to date throughout fiscal '26. Leveraging the financial strength that Jim just outlined, we're well positioned to deliver on our dual-track strategy, growing production whilst containing costs to maintain overall margins and to increase our cash-generating capabilities. We're pretty firmly on track to achieve the top end of our annual production guidance of 155,000 to 168,000 gold equivalent ounces. Now it's worth noting again -- sorry, this will end next financial year, but the true scale of our operational footprint had we included all of the Bjorkdal and Costerfield production for July '25 then the full year guidance would climb to the 160,000 to 175,000 gold equivalent ounces, which firmly establishes Alkane as a mid-tier gold producer. On the cost front, we retain discipline. Our consolidated all-in sustaining cost is on track to hit guidance at AUD 2,600 to AUD 2,900 per ounce or between, if you talking U.S. dollars $1,690 to $1,885 per ounce, albeit we do expect to be at the top end of that guidance. But we do have a pretty aggressive commitment to organic growth. We're deploying in the vicinity of $80 million in growth capital and exploration to keep unlocking value at our sites. Our primary goal for FY '26 was to establish Alkane Resources as a reliable, consistent producer. And I think our performance to date shows that we've done exactly that. Moving on to Slide 16. We remain focused on execution. And as the numbers show, I hope you all think that we're delivering on that promise. We're positioned to meet our targets, both in production and cost. We're deploying the drill bit across our entire portfolio to expand our resource base. This is what we want to do, the bedrock of our strategy. We want to extend our mine life. We want to accelerate production growth at all 3 mines. And of course, we have Boda-Kaiser. This is a very serious copper-gold porphyry project, remains an important part of our portfolio, and we think it's a key for long-term value creation for all of our shareholders. We're moving purposefully on the environmental studies and permitting to advance the project. And in doing so, we give ourselves maximum flexibility to unlock value. Corporately, I think at this time now of the market, our balance sheet is a clear strategic advantage. Given our steady-state operation in this pretty robust still gold and antimony price environment, we expect to continue to build our cash position. This allows us to grow from within as well as inorganic growth opportunities. While we're pretty well positioned to move quickly, of course, we will maintain discipline. In closing, we think we're well positioned to drive long-term value for our shareholders and our stakeholders. And thanks, everyone. With that, I'll hand back to the operator to start the Q&A session. Thank you, operator.
Operator
Operator[Operator Instructions] We are now going to proceed with our first question and the questions come from the line of Lawrence, a retail investor.
Unknown Attendee
AttendeesGood evening in Australia. I'd like to thank the Alkane team for staying up late on a Friday evening. I have several questions, Nick, and I'll start with the first one. When will Alkane disclose the exploration and mining plan for the Nagambie earn-ins?
Nicolas Earner
ExecutivesYes. Lawrence, thank you very much, mate. No problem staying up, but thank you for acknowledging. So Nagambie, at the moment, we're compiling exactly what we're looking to do. However, we've already obtained a drill rig. We're mobilizing that to site. We expect to start drilling in the next couple of weeks. But the first drilling we're looking to do is simply to put sort of 3, 4 holes into the existing inferred resource that Nagambie has in order just to firm it up, redo the model and then start to do targeting. So once we've done that, then we can detail -- a more detailed program. But I would say, probably in reality about 2, 3 months.
Unknown Attendee
AttendeesOkay. That's great. On the Nagambie presentation, I think it's dated 2023, they mentioned Whroo and Redcastle JVs for some of the Nagambie permits that are off, I think, kind of northwest and north of the mine. Are those JVs still in progress?
Nicolas Earner
ExecutivesSo as far as I'm aware, and forgive me, I may be a tiny bit inaccurate. But as far as I'm aware, no, the only remaining agreement is with a company called Golden Camel, who has the right to process material. I'm going to call it the Northeast corner of the mine, a very long-standing relationship there. They, of course, need to attract funding and all the other stuff to do that. So at this stage, though, most of the work that we're doing will be on that primary tenement package in and around the old mines under the old open cut. So if I've stuff that up, I apologize, mate, but our primary target is in and around that existing mining area.
Unknown Attendee
AttendeesOkay. I'm still trying to figure out the Boda-Kaiser project. I'm trying to understand what the profitability is because it seems to look like a Kinross project where you have high tonnage, low grade.
Nicolas Earner
ExecutivesMate, you're absolutely spot on about that. So if we rewind a fair bit to the scoping study that we put out in July 2024. So we looked at a 5 million tonne a 10 million tonne and a 20 million tonne per annum scenario, way back when gold price was AUD 3,500 per ounce, right? And copper was under what it is in today. So gold price now is in Aussie dollars, I'm going to say, AUD 6,400, so another AUD 3,000 per ounce. And copper has gone from being around this AUD 15,000 per tonne to nearly AUD 20,000 per tonne. But you are correct. It is a large, very large, lower-grade deposit, which contains gold and copper in nearly 50-50 value. The overall grade is 0.58 grams per tonne equivalent. That changes, of course, on gold price, but it's comprised of 0.3 grams per tonne of gold, 0.18% copper. So a couple of key things around value. Back then, the IRR was solid, but not amazing. At current prices, if we did 20 million tonnes per annum, the IRR on a pretax basis is up over 50%. So a couple of things that will have changed, of course, since that study. Capital costs will have risen slightly. So we'll redo that as we work through this next year or 2. OpEx will no doubt have been influenced. We're all waiting to see where everything ends up over the next year or 2. But it's fair to say that prices have moved way more as a percentage, gold and copper prices in those terms. So if you look at the 20 million tonne per annum scenario, it averaged over a 17-year life of mine, it would average equivalent of being a bit over 200,000 to 220,000 ounce equivalent operation. If you did a 10 million tonne per annum, it was a tiny bit higher. It was sort of in the 110 to 125 -- so anyway, what you're seeing is in this price environment, it's a very profitable operation, but you're exactly correct. It needs big tonnes. The bigger the tonnes, the better it is. It will start open cut. It will transition to underground in 10 to 30 years depending on what size processing plant is. Look, I will certainly call our executives and check out that scoping study.
Unknown Attendee
AttendeesDo you think ore sorting could be used at the Boda-Kaiser process?
Nicolas Earner
ExecutivesSorry, it's not -- I mean, ore sorting at some of our other prospects, yes, but not this one. It's a really large calc-alkalic porphyry. So no, I don't see we would get an uplift from ore sorting.
Unknown Attendee
AttendeesYes. Okay. I think my next question is, I assume that you've heard about the Trump administration's project Vault.
Nicolas Earner
ExecutivesYes, but I am not an expert, I will be incorrect.
Unknown Attendee
AttendeesYes. So I was wondering if Alkane has had any discussions with the Trump adminfstration with regards to selling antimony into Project Vault.
Nicolas Earner
ExecutivesWe've had, as many people have, because they've been very thorough around the world. We've had some communication around the selling of concentrate once they establish that downstream smelting, yes, but there's nothing committed at all.
Unknown Attendee
AttendeesOkay. Well, at least you're having discussions. That's a good news from my point of view. I'm not sure where they are in developing Project Vault. Obviously, they're going to have some strategic warehousing set up across their country. And I don't know if they're at that stage yet.
Nicolas Earner
ExecutivesThanks for your questions, Lawrence.
Unknown Attendee
AttendeesJust actually, just one other question. Does the Communication Officer or Investor Relations Officer have a phone number?
Nicolas Earner
ExecutivesYes. So if you look on the bottom of any of our announcements on our website, you will see Natalie's contact details there.
Unknown Attendee
AttendeesYes. And I guess the only other piece of feedback I have, and this has to do with my neurological PTSD situation is that today's -- could today's presentation be put in the investor presentations web page just to make it easier to find because I couldn't find the presentation that you were using on the call today. So I'm wondering if it could be put into the presentation section prior to having the investor call.
Nicolas Earner
ExecutivesThank you for the feedback, mate. It is something we will check out.
Operator
OperatorWe are now going to proceed with our next question. And the questions come from the line of Kevin Tracey from Oberon Asset Management.
Kevin Tracey
AnalystsThe first one is on Kendall, pretty exciting exploration results there we announced in February. Can you -- and you mentioned that Kendall is quite close to your existing infrastructure. Can you talk about the timing of when you could mine material volumes from Kendall and how the results change your outlook for the mining plan?
Nicolas Earner
ExecutivesYes, certainly, Kevin. We expect that we'll be mining Kendall over the next 12 months, later in the next 12 months. So the nature of Costerfield as a mine is that we seek to at least replenish the reserves each year. And also, if possible, obviously, we want to expand the reserve for it. The high-grade areas of Kendall we'll be developing up towards and also Brunswick South is a new mining area that we'll be developing towards. So I don't see that significantly changing the outlook from sort of this year's production. But certainly, it will be good to get up there and then start to check it out with some development drives.
Kevin Tracey
AnalystsOkay. And then at Bjorkdal, the production number was the best we've seen in a long time. And my question really is about the gap between the process grade and the mine grade. Or historically, we've seen the process grade be lower than the mine grade as you supplemented underground ore with stockpile. And in the most recent quarter, the process grade was a good deal higher. Is this totally explained by the kind of off-site trial of processing of third-party ore that you talked about? Or it will be explained by something else?
Nicolas Earner
ExecutivesYes, pretty much, Matt. Yes. So the mine that we looked at, obviously, because we're tracking it, had a head grade of, I'll just say, 6 grams per tonne . so you can understand why we're looking to see if that works for us, and there's a whole host of different aspects of that. So yes, that is the main explanation of what to do. We are looking at ore sorting, but no, it's not that. It is all the off-site production.
Kevin Tracey
AnalystsOkay. And are you hopeful that you'll be able to sustain the processing of that ore? Or yes, do you see grade as sustainable in the quarters ahead?
Nicolas Earner
ExecutivesYes, totally. So no, do not put into any model that you might have yet. We are hopeful that we can secure some sort of arrangement from that mine or others. But there's a couple of hurdles to overcome; one, negotiating with those parties. But two, also the permitting, part of the trial was to get tailing samples and other things to make sure that we would be compliant with any of the environmental conditions we have on site, and then we have to test that with the regulator over the coming months to get permission to bring in ore such as this from offsite. So yes, we very much want to pursue it. Yes, we very much want to do deals, and yes, we'll be pursuing with the regulator. But it's more months than years, but it is still something we need to land.
Kevin Tracey
AnalystsOkay. Great. And then bigger picture at Bjorkdal, you have a broader strategy of opening more mining fronts and filling the mill with more underground ore. Can you just update us on the status of those efforts and kind of give us a preview of what we should expect in fiscal '27 in terms of volumes at Bjorkdal underground?
Nicolas Earner
ExecutivesYes. So we absolutely do have a strategy. So there's 2-part strategy. So number one is the pit at [ Newlands ] which is just a tiny bit to the east of where the Bjorkdal open cut was. That's a mine open cut that we've been doing pre-stripping of at present. It's got a stripping ratio sort of the order of 6 or 7:1. And we expect to be delivering ore from that at around sort of this 0.8, 0.9 grams per tonne, which is higher than the low-grade stockpiles later this calendar year, so during the next financial year. So that's sort of part 1. Part 2 is the Storheden deposit to the north of the existing mine. We have a mining lease there, but we need to get the environmental permit to mine that. We have [ commenced ] already the development towards that. So that needs a new cross cut going across from underground and then a decline. That's probably the better part of 3 years activity and an update of the environmental permit. So these are the 2 things we're doing. So next year, I expect our production will be similar-ish to this year. I expect our capital costs will rise because we're looking to invest in those 2 things that I described, but they all will be setting us up for increasing production going forward, ideally the year after and the year after that.
Operator
OperatorThere are no further questions on the phone line. So I'll now hand over to Natalie Chapman for the written questions.
Natalie Chapman
ExecutivesThanks very much. So we'll start off with what opportunities does Alkane see in gold and antimony beyond Costerfield?
Nicolas Earner
ExecutivesOkay. So -- and outside of our own exploration things that I just described, clearly, for us, there's the joint venture with Nagambie in our immediate vicinity. There are some other companies that have gold and antimony deposits more regionally, so we'll call it within 150-kilometer radius. But we're only in the very early. Let's just have a look at these and consider it at this stage. Please don't read too much into that. Looking more broadly internationally, I'm sure many of you that know the antimony market will be aware of other projects. At the moment, at the very most, we have a desktop review of some of those. So we're not actively pursuing in our M&A in antimony lead on anything. We are looking at gold projects and some of them do include antimony, but not really. I hope that answers your question. If it doesn't, please type in another one.
Natalie Chapman
ExecutivesAre you still conducting a geophysical exploration?
Nicolas Earner
ExecutivesAbsolutely. So we've broadly finished our geophysics at Boda-Kaiser because we've updated those with updated gravity, magnetic and other things for targeting. Down at Costerfield, we are almost finished updating our information density there. And we have a structural expert looking at that to assist with our targeting to extend the mine life. At Tomingley, it's similar. We've done further survey work there, geophysics. Most of that's finished. We're now engaging structurally. And we're looking at that deep drilling, I said to test some of the seismic work that we've done there. So I hope I've answered your question.
Natalie Chapman
ExecutivesWhen will Alkane pay its first dividend?
Nicolas Earner
ExecutivesWell, it's something we talk about in the Board all the time, particularly as we have such strong cash flow generation. We're looking to put together a capital management strategy, buybacks, dividends, et cetera. And we expect to announce that in the second half of this calendar year and the first half of next financial year, so we will have a pretty clear idea of the ratio, liquidities and what we intend to do with cash. At the moment, our key thing is to really look at our M&A opportunities and run those to ground. But we're putting out a capital management policy for the end of this year. But I won't -- we do not expect at this stage, even though we talk about it each month, we meet with the Board, we're not anticipating paying a dividend at the end of this financial year. So that may occur, but people should not count on that.
Natalie Chapman
ExecutivesHow much, if any, of the drop in the all-in sustaining cost at Bjorkdal this quarter was down to the trial sample? And would you expect further cost declines there if the outside ore is brought in on a continual basis?
Nicolas Earner
ExecutivesYes, absolutely. So the costs at Bjorkdal are pretty much fixed. They're close to 65%, 70% fixed. So it was definitely the per ounce cost base was absolutely influenced by that offside ore, which is, of course, why we're looking at that and other sources for it. In the event that we do find and follow up the questions I gave, Kevin, around that offside ore, then yes, I would expect the all-in sustaining cost to come down. That's the whole premise of all the different activities we're trying to do Bjorkdal.
Natalie Chapman
ExecutivesCongratulations on a strong quarter and the smooth integration. I appreciate you maintaining a strong balance sheet and the investments in exploration and optimization. With 20% of market cap in net cash and it is building quicker and can be spent. Any thought on maintaining 20% of net cash bullion if successful finding -- if you're successful finding an external opportunity, but allocating a portion of incremental free cash flow to opportunistic buybacks at this level of undervaluation?
Nicolas Earner
ExecutivesYes. So the capital management strategy will no doubt incorporate something such as the questionnaire is envisaging. However, we're also very much looking at dividends given we have Australian franking credits as well.
Natalie Chapman
ExecutivesWhat impact does the rising cost of oil have on your operations, particularly those in Australia?
Nicolas Earner
ExecutivesMan, yes, obviously, topic for all of this. So to date, given that we are grid powered at all 3 mine sites and we're underground, not operations, so lower tonnage movement. The oil price itself, the diesel fuel has not had that much of an impact. It's fair to say I'm pretty concerned about all the flow on things. So things like drill bits with the tungsten as a portion is the cost of those are rising, the cost of poly pipe is rising, the cost of some reagents is rising. And I do have some sympathy for our suppliers as it rises and falls. And when we ask them, okay, we're preparing our budgets for next year, what is this going to be. But to be honest, people can't really tell us that much, right? So directly related to oil, not much; as to where it all settles on the broader, I don't know, I'll just call it, supply base of reagents, explosives, drill steels and other things that transport affected. I really can't say. Today, we haven't seen that flow through. But to be honest, it does feel like it's going to be inevitable and certainly, all the external commentary I read makes me think that as well.
Natalie Chapman
ExecutivesThanks, Nick. We have no further questions. So I'll hand back to you for closing comments.
Nicolas Earner
ExecutivesOkay. Great. Great. Thanks, Nat. Look, thanks, everyone, for taking the time to join us today. And look, while we've had a successful financial year so far, we, of course, look forward to showing more of our progress in the next call in a few months. As always, please reach out if you have any questions. And as I said to Lawrence in our first question, Natalie's details are on the bottom of all of our announcements. So thank you, and good evening to everyone here in Australia, and have a good day, everyone, in Canada. Thank you.
