I will now turn it over to Michael Holmes.
Thank you, Sam. Good morning, good evening to all. I hope everybody is staying healthy. Thanks for joining us today to review our third quarter operating and financial results. Moving on to slide four. Our third quarter results reflect the impact that COVID-19 pandemic has had on our business. During the quarter, we revised our 2020 outlook, which was driven by lower production expectations out of Haile. We are currently tracking to the low end of guidance at Haile, and on a consolidated level, we expect to produce approximately 300,000 oz of gold at consequently higher all-in sustaining costs. At Haile, production and costs in the third quarter were below expectations, with positive COVID cases increasing from two to over 20 at quarter end.
With 330 workers self-isolating since the beginning of March, including 220 from the 1st of July to the 21st of October, this represents 40% of the workforce. Year to date, the site has experienced a 35-year record high rainfall. These factors impacted operational productivity and prevented us from advancing mining rates as originally planned, resulting in delaying access to high-grade ore zones. Uncertainties around COVID-19 remain as cases in South Carolina continue to increase. These are real challenges for the Haile team, but ones they are addressing to safeguard the health and wellbeing of our workforce and delivering on expectations, which include maintaining higher plant throughputs, improving recoveries, and staffing up to counteract workforce disruption due to illness and absenteeism. In New Zealand, Macraes is tracking to their full year guidance of 140,000-150,000 oz of gold.
Macraes has bounced back well from the second quarter suspensions, and the team is delivering on all fronts. On the North Island at Waihi, despite the five-week development hiatus in the second quarter related to COVID restrictions, the Martha Underground is on track for first production in the second quarter of 2021. We have advanced over 2 km of underground development during the quarter and over 5 km year to date. Project to date, sorry. By year-end, we expect to be developing approximately 900 m per month. At a total company level, our financial results are consistent with underlying operational performance and broadly in line quarter-on-quarter. A higher gold price helped to offset generally lower gold sales as a result of no sales from Didipio, and lower than expected gold sales from Haile in the third quarter.
Quarter-on-quarter, adjusted EBITDA increased from strong production from Macraes and a higher gold price. Subsequent to quarter end, we made the difficult decision to permanently lay off approximately 900 full-time and contract workers at Didipio, given the inaction related to our FTAA renewal and ongoing blockade of the access road by the local government units and the minority of individuals who are ideologically opposed to mining. Our net loss of $154 million year -to -date, and $97 million in the third quarter, reflects the pre-tax impairment charge of $80 million related to the carrying value of Didipio. Our third quarter adjusted net loss of $24.9 million resulted in an earnings per share of negative $0.04, which was flat quarter-on-quarter. Cash flow per share was $0.11 year to date and $0.02 in the third quarter, excluding the gold pre-sales for each period.
Despite the challenging year we've had, we remain committed to delivering the most value to our shareholders over the long term, and we will achieve that by progressing our dynamic organic growth pipeline and executing on our operational plans while managing the continued risks we face. During the quarter, we finalized optimization of the Horseshoe Underground at Haile, while solidifying our long-term vision for the asset. Martha Underground at Waihi is progressing well, and Frasers Underground at Macraes, the development will begin this quarter with first production expected in late 2021. Permitting and exploration is ongoing in New Zealand, setting the stage to realize the full potential of the greater Waihi district. Turning to slide five. We have strict protocols in place at all sites to maintain the health, safety, and wellbeing of our workforce. This is a top priority for us.
These protocols enforced at all sites, and for our corporate staff, include workplace health screening, staggered shifts, rigorous cleaning practices, and working from home where practical or mandated. As at the October 22nd, the Haile operation has recorded 25 positive COVID-19 cases, including five cases in the fourth quarter thus far, with only one active case, along with another nine presumptive positive cases under watch currently. Over 330 Haile workers have had to self-isolate for two weeks at some point in time since the beginning of March, including 120 in the third quarter and 50 thus far in the fourth quarter. The New Zealand government lockdown in the second quarter successfully managed the spread of the virus, and to date, we've had no positive COVID cases at Macraes or Waihi.
To date, 30 of our workforce has tested positive for COVID-19, 25 based at Haile, four at Didipio, and one from our corporate team. Despite these challenges, our safety performance remains relatively stable quarter-on-quarter, resulting in the company's total recordable injury frequency rate trending to 2.9 per million hours worked. During this uncertain time, we continued to achieve strong safety results and will continue to do so through strong leadership and communication to ensure the trend continues in the right direction. Moving on to slide six. We have operated a sustainable business for the past 30 years by applying robust ESG practices across our business, this year we continue to advance key initiatives to keep us at the forefront of best practice globally.
We are progressing our approach to climate change with the development of work plans, measures, and targets related to this very pressing global issue. This includes our commitment to provide short-term targets in line with the Task Force on Climate-related Financial Disclosures by the end of 2022 and our commitment to other long-term goals. The work is already happening on how to reduce emissions across our business, particularly as we deliver our organic growth plans. We are evaluating mine plans and designs within the context of using low-emission fleets, particularly in our underground operation. The innovation and focus on change is underway. We look forward to sharing more details on our climate change-related work before year-end.
In addition, we received assurance on our first phase of compliance with the World Gold Council's Responsible Gold Mining Principles and expect to be in full compliance with these standards by the end of 2022. Our overall ESG performance has been recognized by the major ESG rating agencies, and most recently, we maintained our A rating with the MSCI, an outperformer ranking by Sustainalytics, putting us among the elite ESG performers in the mining industry. Moving on to Haile on slide seven. Haile, with the many challenges we faced there year to date, continues to see safety improvement. The total recordable injury frequency rate trended lower in the third quarter to 5.4 versus 6.3 in quarter two. I attribute this to the strong leadership we've put in place at the operation, ingraining our safety culture that requires continuous employee engagement.
The third quarter at Haile was as expected, given the challenges we faced. COVID cases increased dramatically and exceptional rainfall hindered productivity. Rainfall totaled 51 in through September, the highest amount on record for the last 35 years. Despite these impediments, the team at Haile has kept the operation moving forward in all aspects on the mine activity and project development. 30% of our workforce self-isolated in the third quarter due to the COVID, and positive cases increased tenfold. The disruption in workforce resulted in the haul truck utilization rates of 60% year to date, which is much lower than our expectations for the year. Quite simply, because of these factors, we were unable to advance our mining rates as expected, resulting in delayed access to the higher-grade ore zones. Production was lower, and costs were higher during the quarter.
Mining and processing unit costs increased 26% and 23% respectively, quarter-on-quarter. Higher mining unit costs reflected increasing headcount and training to offset absenteeism impact. A 30% increase in the cost of diesel during the quarter, and more drilling and blasting of material in the open pits as the mine plan progresses. Higher milling costs reflect utilization losses from wet in-circuit material, plus a three-day planned maintenance shutdown, which was brought forward from October. Quarter-on-quarter, we had quite a bit of noise, but year-on-year, there is a trend of improvement across the board. 2020 year-to-date figures over 2019 results have shown significant improvements in total material mined, ore mining increasing, mill feed increasing, recoveries improving, and costs improving. We're on the right path at Haile, and despite the detour of 2020, we have not lost sight of the long-term potential of the asset.
Turning to slide eight. Here you will see proof of the points related to the challenges we faced in the third quarter and continue to manage at Haile. The reality is that the Carolinas continue to experience excessive rainfall, and although we've had factored in rain when establishing our budgets and guidance, it is a variable that we cannot predict. Despite the rainfall, take note that we are moving more of South Carolina than ever, averaging 3.3 million tonnes per month since the beginning of this year. Despite receiving more rainfall than ever, we've experienced since the beginning of the operations. We continue to work through expanding the pits and mining through the clays and saprolites to get to the harder rock, which we expect will improve productivity independent of weather events.
We've been successful at reducing total turnover to less than 25%, attributable to better recruiting practices and employee targeting, as well as on-the-job training. We're also increasing staffing levels to mitigate and manage absenteeism from COVID and turnover. COVID-19 remains a challenge for us as cases in South Carolina continue to escalate. With our strict protocols in place, we have prevented the spread at site thus far. Notwithstanding the continued risk associated with the pandemic, we expect continued improvement from the team at Haile. Turning to slide nine at Macraes. During the third quarter, Macraes Operation reported two reportable injuries, bringing the year-to-date total to three. The resulting total recordable injury frequency rate was 2.3 per million hours worked. The operation continues to see a significant reduction in the number and severity of injuries as compared to last year.
In the third quarter, Macraes produced approximately 35,000 oz of gold and increased quarter-on-quarter as we resumed full-scale mining and processing post-government imposed COVID-19 restrictions in quarter two. Open pit and underground mining costs generally increased quarter-on-quarter with the resumption of normal operations during the quarter relative to quarter two. Processing costs also increased quarter-on-quarter due to planned maintenance shutdown completed during the quarter. all-in sustaining costs of $1,482 per oz sold were noticeably up quarter-on-quarter, reflecting the resumption of the pre-stripping activities relative to quarter two and increased sustaining capital spend related to a public road realignment project. The road realignment project is imperative to facilitate the mine life extension to 2028 that we shared as part of our updated technical report.
We expect Macraes to produce over 1 million oz at an all-in sustaining costs of approximately $1,000 per oz sold over the next eight years. The development of Golden Point Underground and additional open pit opportunities at Deep Dell, Innes Mills, and [Gay- Tan] have increased the mine life. We expect to invest approximately $15 million to develop the Golden Point Underground, which effectively replaces the Frasers Underground. We will invest an additional $30 million annually in sustaining capital with the open pit expansions. For 2020, Macraes is tracking comfortably within the full-year production guidance of 140,000-150,000 oz of gold. We continue to expect the quarter to be the highest quarter of production at the lowest corresponding all-in sustaining costs, particularly as sustaining capital investments taper off. Moving on to slide 10 and Waihi.
Recorded zero injuries during the quarter, and it's maintaining its total recordable injury frequency rate relative to quarter two. Development of the Martha Underground continues to progress on budget and on schedule for the full year, despite the temporary curtailment in the second quarter due to COVID-19 related restrictions. With total advance rates continuing to increase, and at the end of quarter three, we completed 2.2 km of underground development. First production of stope ore from Martha Underground is tracking to the second quarter of 2021, and that will be supplemented with stockpiled development ore as we advance the project. Looking ahead, the processing plant, which was shut down in February after completion of stope mining at Correnso, will resume batch processing this quarter with ore from narrow vein mining in the Upper Correnso and Lewis veins.
We're expecting 7,000 - 8,000 oz of gold production from Waihi in the fourth quarter, bringing total production to approximately 20,000 oz of gold this year. Moving on to slide 11 and Didipio. Our focus at Didipio is on lifting the operating restraints at the mine and renewing the FTAA. During the third quarter, the community of Didipio held a General Assembly on September 10th, and 400 community members participated, representing the majority of the Didipio families. The General Assembly passed resolutions supporting the resumption of free travel for Didipio mine supplies and product, effectively supporting the removal of the blockade, and requested that Didipio Council, which has been active in establishing and maintaining the blockade, support these resolutions. To date, the resolutions of the General Assembly have been opposed by the local leader and his coalition on the Didipio Council, and as such, the blockade remains in place.
Despite the efforts of the General Assembly, the mayor and the municipal council agreement to remove the blockade and the anti-mining activists manning the blockade could not be achieved. As a result, and in accordance with the Philippine labor laws, we terminated the employment of 496 employees and 400 contractors on the 13th of October. This is a very disappointing outcome for us, and most especially our dedicated and skilled Filipino workforce, as well as the broader barangay. Didipio is a significant source of jobs, social development, taxes, and revenues that we believe will be critical in contributing to the Philippines' post-COVID-19 recovery. With the permanent layoff of the majority of the workforce, our focus has been turned to transitioning Didipio to a state of operational standby.
Our expected timeline for resumption to full operations has now extended to up to 12 months, as it would take considerable time and effort to rehire and retrain our highly skilled Philippine workforce. We continue to seek temporary injunction against the governor's order restraining the operations. We have received word that our appeal to the Court of Appeals for temporary injunction has been denied, and we are currently evaluating the option to appeal this decision to the Supreme Court. Concurrently, we remain in dialogue with the appropriate representatives at the national level on the renewed status, and currently, our understanding is the FTAA remains with the Office of the President for approval, but we do not have visibility on a timeline for action from the President.
I will now turn the presentation over to Scott to take you through our financial results.
Thank you, Michael, and hello, everyone. The next few slides, as Michael said, will summarize our third quarter financial results. Turning to slide 12, which provides a snapshot of our balance sheet. As noted, as at 30 September, our cash balance was $127 million, while our net debt stood at $187 million. We have been actively managing our liquidity position for some time in response to the suspension of operations at Didipio, as well as the planned production pause at Waihi. This has included debt amendments late last year, the sale of our interest in GSV in Q1, and the gold pre-sale arrangements executed to better align our near-term operating cash flow profile with our 2020 capital investment plans. Our 2020 plan included a strengthening operating cash flow consistent with increasing mine grades at both Haile and Macraes across the third quarter, and even more so into the fourth quarter.
However, the five-week COVID shutdown at Macraes impacted mining progress, and in doing so, delayed access to some higher-grade zones in the context of the third quarter. Haile has experienced similar timing challenges, with the management of COVID resulting in increased workforce absenteeism due to isolations and case management. Again, this contributed to reducing mining productivity and delayed access to higher-grade zones in the third quarter. While we have proactively managed the material impact these short-term challenges have had on liquidity, and we expect improved performance in the fourth quarter, the key to realizing the value with OGC is not just managing these short-term risks, but at the same time ensuring we can commit to delivering the significant organic growth projects in our portfolio despite these risks.
To achieve these goals, we felt additional equity was the best path given the increased risk over Didipio timing, while also considering the significant capital investment commitments required to bring these projects to fruition over the next few years. The equity raise announced in September was completed this month, and as noted, a total 81.6 million common shares issued for net proceeds of approximately $122.4 million. The completed transaction included the exercise of an overallotment option of 8.6 million shares. As previously advised, the bulk of the proceeds are earmarked to underpin the Horseshoe Underground mine development at Haile, development of opportunities in the Waihi District, and importantly, also ongoing exploration to further enhance the value already evident in the Waihi region.
While we continue to face uncertainty over the trajectory of COVID in the U.S. and broader economic risks remain, we believe we can now move forward with confidence and commitment to delivering operational performance and these significant value-enhancing growth projects, while at the same time retaining their full value and optionality in the hands of the shareholders. Moving to slide 13 and the financial results summary.
The overall third quarter result was a net loss of $97 million, which included an impairment charge of $80 million related to Didipio. This followed the announcement of the planned workforce terminations in the third quarter, first tranche of which occurred in mid-October. These terminations will result in an expected change in the status of the asset, as Michael has explained, effectively, as previously highlighted, the operation will transition from a state of operational readiness for rapid restart to a reduced status of operational standby.
This change is expected to materially impact the timeline required to resume full operations subsequent to a resolution of blockade or a decision by the Office of the President on the renewal. The carrying value of the asset was reassessed at the end of the quarter to include this change in assumption, and this reassessment resulted in an impairment charge as included in the third quarter results. Carrying value of Didipio will continue to be reviewed based on the situation on the ground, and with respect to progress with the FTAA renewal. Should a positive outcome be achieved and the operational ramp-up happen more quickly than anticipated, the carrying value may also be reassessed on that basis. Aside from the non-cash impairment recognized, the underlying third quarter financial results were consistent with the operating performance during the quarter, and both were broadly consistent with the previous quarter.
The year-on-year reduction in both EBITDA and revenue largely reflects the lower gold production and sales at Didipio, but also the planned production pause at Waihi, where there has been no production in the second and third quarters. A marginally higher average gold price realized, combined with stronger production quarter from Macraes, effectively offset the small reduction seen at Haile. The adjusted third quarter result, excluding unrealized gains and hedge gains, and the impairment charge, was a loss of $24.9 million, or negative $0.04 per share, fully diluted. On a quarter-on-quarter basis, EBITDA was largely comparable. The adjusted EPS improved by $0.01 per share, and the cash flow per share before working capital movements was flat at $0.02, bringing the year-to-date total to $0.11 per share.
Generally, our financial outlook for the final quarter is materially stronger, based on higher production from both Macraes and Haile, combined with the restart of the plant at Waihi to batch process accumulated narrow vein ore stocks. Based on current gold prices and this improved production outlook, we are targeting a return to underlying profitability in the fourth quarter. As per the cash flow summary at the bottom of the slide, year to date operating cash flow has increased due to the receipt of $155 million from the previously announced gold pre-sales, which totaled 88,000 oz. 48,000 oz are due for delivery in 2020, with the remaining 40,000 for delivery in Q2 2021. During the third quarter, the first 12,000 oz due this year were delivered. The remaining 36,000 will be delivered in the fourth quarter.
The year-to-date investing cash flows reflect increased capital investments for growth projects, partly offset by proceeds from the sale of our GSV investment earlier in the year. The quarter-on-quarter increase in investing cash flow largely reflects increased pre-stripping activities and growth capital at Haile. Cash used in financing of $6 million reflects finance lease repayments, with our debt facilities unchanged during the quarter. Turning to slide 14, which provides some additional detail on the capital expenditure for the quarter. As outlined at the top of the table, total capital expenditure was approximately $82 million, a 50% increase on the prior quarter. Just under half of the quarter's capital spend is attributable to increased capital investments at Haile, where major works included the completion of the second TSF Wall Lift, commencement of work on a third lift, plus heavy earthworks related to PAG cell construction.
Haile also saw higher pre-strip consistent with the mine plan. The balance was split equally between Macraes and Waihi, both approximately $20 million each. At Macraes, sustaining capital increased with a full quarter of mining, including ongoing pre-strip at Coronation North Stage 4, plus the road realignment project being a key feature in the quarter. Waihi included the continued development at Martha Underground, plus increased exploration spend covering both Martha and WKP.
I will now turn it back over to Michael to discuss our exciting organic growth pipeline further.
Thank you, Scott. Moving on to slide 15. During the third quarter, we delivered a comprehensive update of our exciting portfolio with the finalization of the technical reports for our operating assets. The results demonstrate real value over the long term. We believe delivering our dynamic organic growth pipeline is critical to creating shareholder value. The future of OceanaGold is in two top-tier jurisdictions, the Americas and New Zealand. Beginning with the growth in the Americas, we finalized the optimization of the Horseshoe Underground at Haile in the third quarter and solidified our view of the asset's long-term potential. We see an exciting underground future at Haile, supplementing the open pit operations, and it is our desire through the drill bit to continue to increase the life of the underground project. We envision Haile as a 200,000 + oz producer at a sub $900 per oz, all-in sustaining cost.
The near-term investment in waste storage facilities supports this vision and generates active life of mine free cash flows and [activates]. The company is in the final stages of the supplementary environmental impact statement process to expand the Haile operation. The SEIS facilitates continued development of the existing Haile footprint, expansion of the TSF and waste dumps, and a commitment of the mining from the underground Horseshoe mine. To date, there have been no objections by any stakeholder group to the SEIS, and at this stage, the company anticipates a successful record of decision and completion of the process by the first quarter of next year. The majority of exploration activities are in New Zealand, where we have operated responsibly for the past 30 years, creating significant value for shareholders and socioeconomic benefits for host communities, regions, and the country.
Martha Underground underpins the greater Waihi district as we currently see it. It is fully permitted, currently in development, and on track for first production in quarter two 2021. As we develop the Martha Underground project, we will continue to invest in the drill bit. We believe the Waihi district represents the largest value-creating opportunity we have in our portfolio, and exploration is expected to continue for years to come. At Macraes, the updated 43-101 technical report reflected a mine life extension to 2028 with the development of the open pit opportunities and the Golden Point Underground. Golden Point Underground is expected to replace the Frasers Underground and extend the mine life in Macraes at production levels of 150,000 oz-180,000 oz a year, and all-in sustaining costs of around $1,000 per oz.
We continue to expect Macraes to be a major source of free cash flow generation for many years to come. Turning to slide 16 for Haile growth. As I stated before, the exciting future of Haile is underground. During the third quarter, we completed the optimization of the Horseshoe Underground, including pursuit of a bottom-up mining approach with the use of a cemented rockfill backfill. Portal development for the Horseshoe is expected to begin next year with the receipt of the SEIS, and first production is currently tracking to 2022 year-end. The Horseshoe Underground is one of several underground exploration targets at Haile, which was recognized as part of the original due diligence. These targets stretch over one kilometer from the Horseshoe in the east to the Palomino in the southwest.
In 2016, we drilled the upper portion of Horseshoe with some excellent results that have now converted to a reserve of approximately 500,000 oz , along with the substantial inferred component still to be converted at depth, at deeper levels. Significant extensions to Horseshoe also remain to be tested, as highlighted in the figure on the left, with 64 m at 15 g/t of gold. Palomino was the next opportunity to be drilled with a substantial inferred resource of approximately 600,000 oz being booked earlier this year. As part of this work, we also identified the Snakeshoe and Pisces targets, with excellent drilling intercepts in addition to a large conceptual target still to be tested called Aquarius. Each of these substantial opportunities will be advanced over the next several years.
In addition to exploring underground, we continue to drill ahead of the open pit operations and expand opportunities at surface. Turning to slide 17. Martha Underground is advancing to first production in the second quarter of next year and is the foundation asset for a district with enormous potential. Exploration efforts year to date at Martha Underground have focused on resource definition in support of feasibility level studies currently underway. We have not fully defined the resource at Martha Underground to date, with additional areas highlighted for further drilling programs and definitions. Located 10 km to the north of Waihi, we continue to believe that WKP will grow into a multi-million dollar ounce deposit, and we will dedicate the drilling resources to highlight this.
WKP is a major discovery with a resource of 1.1 million oz grading between 12 and 13 g/t based on only 35,000 m of drilling. Throughout 2020, the company has been focused on step out and infill drilling of the Eastern Graben vein to further delineate the resource. Also during the third quarter, the mining permit application for WKP was approved, granting us exclusive right to the WKP mineral resource. We look forward to continuing our robust exploration program there, along with other technical and environmental studies. Turning to slide 18. At Macraes, development of the Golden Point Underground underpins the mine life extension. Services and earthworks around the portal have already commenced, and we expect to begin portal construction for the Golden Point Underground before year-end or early next year. In addition, we are progressing an open pre-feasibility study for the Round Hill, Golden Point area.
As part of this, an evaluation will be undertaking a comparison between the underground and open pit mining options for the existing resource. This study is expected to be completed in the first half of next year. In summary, and moving to slide 19, 2020 has been a challenging year. This is not where we expected or wanted to be. I'm sure many of you have reflected on 2020 and feel the same, as we all face an unprecedented global pandemic. My team and I have had to make some challenging and courageous decisions heading into the fourth quarter. On October the 13th, we permanently laid off 496 employees and 400 contractors at the Didipio, which was extremely disappointing. Given the impact of COVID-19 on the Philippines, it is hard to understand. We are a responsible contractor to the national government, and we can assist them on so many levels.
I use the term courageous because it's not easy to terminate employment of nearly 1,000 Filipinos that I helped hire. As difficult as the process is, it is the right path for OceanaGold. It is the right path for us to take on behalf of each of you, our shareholders. Six days after the permanent layoffs at the Didipio, we closed our bought deal offering. This also was not an easy decision for us. We evaluated all options before moving forward. As we close out this year and look to the future, our approach will not falter. We will not deviate from a path that delivers the most value to our shareholders over the long term, and we believe that path means progressing our dynamic organic growth.
Looking to the future, we see our most promising growth projects coming online, and we will continue to make the hard decisions to keep us on the right path to deliver enduring value. It has been a difficult year. The uncertainty of Didipio and the conditions of Haile have been challenging. However, nothing has fundamentally changed with our assets. In fact, we are accelerating our exploration focus in New Zealand and at Haile to convert resources to reserves, better define our assets in development, and deliver the enormous potential we see today. Nothing has fundamentally changed with our team. We are operating in top-tier jurisdictions with decades of experience. We have all the right ingredients for success. We have a solid plan to deliver on quality assets in top-tier jurisdictions under the stewardship of good management.
We expect improved performance in the fourth quarter. The key to realizing value within OGC is not just managing these short-term risks, but at the same time ensuring we can commit to delivering the significant organic growth projects in our portfolio in face of these risks. We are focused on progressing our growth, which means building three underground mines, Haile, Martha and Golden Point, expanding our open-pit operations, and continuing to explore the greater Waihi District. We believe this translates to real value for our current and prospective shareholders over the long term. Early next year, I look forward to sharing more details, including our path forward and our vision for the future of OceanaGold. In the meantime, we'll be heads down executing on the day-to-day and focusing on our path forward to deliver value over the long term.
We are a resilient and dynamic gold miner with a strong and sustainable future ahead of us. Our organic growth pipeline is one of the best in the industry. It represents decades of opportunities for our company. My team and I look forward to delivering that value. Now back to Sam. Thank you very much.
Thank you, Michael. That concludes the formal presentation segment of the webcast. I will now turn it over to the Operator to facilitate the Q&A session.
Thank you. Ladies and gentlemen, if you do have a question at this time, please press star followed by one on your touchtone phone. You will then hear a three-tone prompt acknowledging your request. Should you decide to withdraw your question, simply press star followed by two. If you are using a speakerphone, we do ask that you please lift the handset before pressing any keys. Please go ahead and press star one now if you do have a question. Your first question will be from Ovais Habib at Scotiabank. Please go ahead.
Hi, Michael and team. Thanks for taking my questions. Just starting off at Haile. Based on the implied production needed to meet the lower end of guidance, obviously Q4 needs to be a pretty strong quarter. Can you give us any color on how Q4 is going based on what you've witnessed in October so far?
Thanks, Ovais. Look, it has been a bit challenging year, as mentioned, at Haile, and we are focused on delivering the guidance. We're opening up the areas at Snake Phase 2. We're finishing off the Red Hill pit and mining into the Ledbetter Phase 1. We are actually getting down into the higher grade portions. October is advancing as per the expectations. This will be an important quarter for us, and it has been the deferral, that high grade, but we're advancing to the expectations to deliver the lower end of the guidance.
In terms of, you said that employees that are in quarantine, the number of quarantine in Q3 were 160 employees, and then it's come down to about 50. Obviously, then utilization of equipment has moved higher and has that helped kind of moved material even further?
Part of the actions that's been taken on site, and Jim can talk a bit more to this, is that we've actually, because of the impact of the absenteeism on site during the third quarter, we've engaged a local labor company that actually has been supplementing the workforce, we're actually moving through with the number of people on site, which improves the utilization of the equipment. That has improved, and that's been an action that's been taken on site to mitigate the absenteeism and impact of COVID.
Okay. Just again then, in terms of the amount of tonnes you mined, it was about 707,000 tonne of ore at 1.69 g/t , and you milled 864,000 tonne at 1.26. Can you give us a breakdown of what tonnes and grade came from stockpiles and what tonnes and grade came from the mined material? I'm assuming you have a high grade stockpile going into Q4.
Yeah. Look, thanks, Ovais. I'll actually hand that question over to Jim with some of the more specific sort of detail.
Yeah. Hi, this is Jim here. Yeah, great question. Thank you very much. Glad to hear from you again. The focus is obviously, as you see, we mill more than the ore mined up to the mill, and that slightly dilutes the tonnes. We have quite a bit of stockpile, up to about 1 million tonnes at about 0.7. That's why you see that impact. The plan going forward into this final quarter, over 70% of the material is really going to be focused on Snake Phase 2. That will be both tonnes and grade will be higher from that area, where also about 20% will be from Ledbetter, where we're opening up the center of the mine. The grade's slightly lower, but the tonnes, again, about half of what we're getting from Snake Phase 2.
We've really positioned ourselves into the center of the ore body, opening up the middle part, and connecting Snake and Red Hill.
Got it. Jim, in anything you need to do going forward to mitigate the risk of additional wet weather going forward, obviously, kind of getting used to the fact that there's a lot of rain in this area, and that has been impacting your mining rates on and off, is there anything additional you need to do to mitigate that risk?
Currently, what we're doing, when we were working only in Snake and Red Hill, we were doing a lot of work in doing drop cuts off of the ramps and creating sumps, so we could try to channel some of the water into the lowest part of the pits. In Ledbetter, it's a much more wider area. We found that that methodology doesn't work so good. Typically, what we're doing now, we're pulling water out of those three areas. We're putting the water into Mill Zone, Mill Zone is actually our transfer point into the water treatment plant system. Really, a couple of things. One is active sumping in the lower areas. Having a wider area in Ledbetter also helps, it's part of the mine design.
The back end of the process plant, which is the water treatment plant, is very important to us to be able to manage this complete flow of water through the system, from the mine into Mill Zone pit and then back out to the treatment plant.
I think some other actions we've taken there, Ovais, that Jim hasn't talked about is just some of the selection of the equipment. A larger grading fleet to manage post the rain events and allow us a faster re-entry time.
Right. I appreciate the color on that. Just lastly, Michael, regarding your credit facility that's due by the end of 2021, are you engaged with any of your lenders to potentially push that credit facility forward?
Yeah. Look, Ovais, we've had a great banking group for a long period of time. Post the equity raise, it is an action that we're following up with Scott and the team to talk with the credit facilities and see what we can do there with regards to pushing that further out.
Thanks, Michael. Thanks for taking my questions. That's it from me.
Thank you, Ovais.
Thank you. Next question will be from Nick Herbert at Credit Suisse. Please go ahead.
Thank you. Hi, Michael and team. A few from me, please, on Didipio. Sad to see the layoff of staff there. Just wondering, since that, has there been any perceptible change in government engagement or not at all? It doesn't really sound like there has been any change, but maybe if you could just make a comment on that.
Thanks, Nick. Through the quarter, we have had numerous discussions with the government. I've had discussions with the secretary of the Department of Finance and the Executive Secretary, trying to get some further color on if there is anything else outstanding that we're required to do with regards to the recommendations that the working group gave to the President, and trying to get a little bit more color on what is happening with the timelines. At this point in time, the president is fairly busy with managing COVID within the country, and certainly a lot of his support staff are managing that issue as well. We continue to be engaged with the undersecretaries and the deputy executive secretary of the Office of the President. As mentioned, the renewal is still with the Office of the President, and we're still in discussions with them.
Unfortunately, we just haven't been able to sort of secure what some of the outstanding timelines might be with regards to the renewal process.
Okay, understood. Thanks. Do you mind just stepping through the costs from here, the redundancy costs, ongoing holding costs, and if there are any other sort of upcoming decisions, points, or lumpy payments that we should be aware of?
Yeah, sure. The layoffs will happen in two tranches. One tranche was the 13th of October. The second tranche will be around the 12th of November. The first tranche was a lot of the Filipino workforce. The second tranche includes more of the senior workforce, both Filipino and expat. Total redundancy costs are around $8 million, and you'll see in the third quarter results there is an approval of $3.2 million. We approved for the first tranche in the quarter three of $3.2 million. The remainder, $4.7 million, will come through in the fourth quarter if we don't see any advancement on the FTAA before the 13th of November. Ongoing cost then is around to keep it in a state of operational standby and to ensure that the asset isn't overrun by water.
The majority of the cost is in power to de-water the mine. That's an average cost of around about $1.5 million per month run rate for ensuring that the environmental compliance, the security of the assets, and the security of the underground.
Okay, cool. That's pretty much covered it all. Okay, great. Maybe just one for you, Scott. Do you mind just talking through what the assumptions are that underpin that written down values for that sort of $540 million recoverable value you have there at Didipio? What does that assume sort of full reserve recovery or sort of what goes into that number?
Thanks, Nick. It's a fairly, I guess, unique situation. What's changed and the reason we had an impairment is probably where to start. Nothing's changed in respect to the renewal process. We're still working through that. We're still engaged with the government, as Michael said. What has changed materially and is the reason that we reassessed the carrying value was the trigger being the termination of the workforce, and the expectation that that will extend the time to restart the asset. The analysis around the carrying value was based on a number of scenarios, which we feel is the most appropriate way to do it in this instance. The delay that we're assuming now to start to generate cash flow again from the asset beyond a decision to restart has a longer timeline to it, and therefore the discounting factor starts to come into it.
Essentially, we're using a probability sort of weighted analysis that now has a longer gap before we're likely to see any cash flow from the asset, and that's what's driving the carrying value assessment. We'll continue to monitor that as we go forward, obviously, based on changes on the ground. As I said previously, that we've got an assumption that the full 12 months plus some time for renewal, et cetera, is the current view. If we do better than that and we do get it up and running sooner, then that carrying value can be reassessed on that basis as well.
Okay, great. Thank you. Then final one, just a quick one. Do you mind just reminding me around the timing at Haile and sort of the mining schedule when you get through into that well predominant sort of harder ore zone? Is that sort of a Q1 next year?
Yeah. Nick, there's a phased approach with regards to the opening up the Haile ore bodies. The ultimate pit sort of includes six ore bodies, and we've opened up Mill Zone. As we do future cutbacks with Mill Zone Phase 2, we've opened up Snake 1 and currently opening up Snake 2, and opening up Ledbetter 1. There'll be different phased approaches with regards to those zones, and that'll happen over the next five years. The idea is that with the, sorry, over the next three years. The idea is that as we sort of open up the larger areas, as Jim explained, with Ledbetter in the surface area, and getting into the harder rock, we've got a lot more optionality there. The impact of the weather with the harder rock as we open up the pits in Snake Phase 2, Ledbetter Phase 1.
The cutbacks then won't have as much impact with regards to the weather, as we'll have alternative places to mine. From a pure mining point of view, we'll see the softer material to be continued to mine to 2023.
Okay. Understood. Thanks, guys. I'll pass it on.
Thank you. Next question will be from Mike Parkin at National Bank. Please go ahead.
Hi, guys. Thanks for taking my questions. On Haile, just flipping back to slide eight. You've got that line in there, 35-year monthly. Can you just remind us what the technical report kind of assumes, what your budget process, I don't think you use the 35-year average, if I recall correctly?
Yeah. Thanks for that, Mike. I'm just trying to remember. We've basically, used around about a month of rain impacts in our budgeting process. A 35-year history basically doubles that amount of impact. It takes it up to around about 55 days. We've historically haven't looked at the 35-year extreme events. We've taken the last, well, previous to 2018 and 2019, that's taken the last 10-year average. Which has historically been around about that 4-6 in a month. We're seeing some excessive. Going forward, part of the process that we have done is we've taken that into account. We've built some additional rain-affected days in 2021. We've reduced the total amount of material mined, as we've highlighted in the technical report, down to 45 million tonnes from that 50-55 million tonnes going forward.
What we are doing is we're accounting for that. We haven't finalized the budgeting process this year to understand some further risks and risk mitigation around how we manage the total process and having the call. We'll dialogue that towards the end of the beginning of next year with our guidance reset. We've certainly in the NI 43-101 have positioned ourselves to actually understand that and better management, but as well as the management of the impact of the rain on certain facilities and certainly the clays and the saprolites.
Right. If you go back a year plus, there's a pretty dramatic improvement there on tonnage, despite what's clearly still rainy weather. Is that a function of just getting the open pits opened up, but also the benefit of the new mine fleet that was coming into service around that time?
Yeah. Look, Mike, it has been a bit of both. Basically we've, initially to sort of pay back the purchase, two areas we used were little smaller pits into Mill Zone and then Snake Pit. During this process, we've set to uncover the ore body and unlock the value. We need to move a lot more dirt. We reflected on the previous fleet and then they've upgraded the fleet, basically doubled the size of the fleet, and hence we've been able to double the movement and still looking for improvement on top of that.
Just looking at the other chart there, the 12 months rolling average employee turnover. Obviously a good improvement from a year ago. If it's still sitting north of 20%, I recall from past mine tours, there was a partial drive of just a safety culture decision of management saying, "You're not fit to work here," if you don't want to wear your safety goggles and that kind of thing. Is that still the case of why you're north of 20%, you're still seeing a bit of a safety culture unwillingness to adopt the standards that you guys are trying to implement to keep your workforce safe? Or is there another dynamic that's taken over as the dominant one causing the turnover?
That is a good question. I'd say, just with regards to the safety, if you have a look at the figures and the total recordable injury frequency rate improvement, there's certainly been, and certainly a reduced turnover assists that. There's been an enormous improvement from the 2014s to 2018s when we first started the project back down to now the 5.4, which has been a great improvement. There's a lot more buy-in by the workforce at this point in time. That's been fantastic. Predominantly what we're seeing, and Jim can answer a little bit more to this, is that there are a few people that still aren't taking up our belief on the culture of safety. The percentage of employees that leave, generally due to personal reasons as of employees that are terminated, would probably, I think, be around the 50/50%.
We still have active management of people on site.
Right. Adjusting for that, it's pretty normal rate. Okay. That's it for me, guys. Thanks very much.
Thank you. Next question will be from Daniel McConvey at Rossport Investments. Please go ahead.
Yes, hello, Michael and everyone. A couple of questions. Didipio, remind me, do you have any option to go to arbitration if necessary?
Daniel, thanks for that. Look, there's arbitration in the contract. It is an FTAA. It is the first FTAA renewal that the government is working through. There are conditions within the FTAA that have defaults.
Just remind me, what the FTAA stands for.
It's Financial and Technical Assistance Agreement. Basically we provide finance and the technical expertise to the government to extract the resources, and it's a 60/40 split after the cost of capital. We're fundamentally being a contractor to the government. With every contract, there is the ability to go to arbitration, yes.
Okay, great. Second for Haile, maybe a simpler question with the wider issues. I guess I've not been there. It sounds like it's unlike most North American mines in terms of mining in wet weather because of the saprolite. Can you maybe just explain why it's more difficult in heavy rainfall than it would be elsewhere in North America, if that's the case?
Okay. Look, Jim, I think Jim's living it, so I might hand that one over to Jim just to run through where the areas of concern are and how they're mitigating and managing that.
Yeah. It's definitely around the nature of the rock. We've been basically mining or developing this site through initial pioneering down through the upper levels of the open pit mine. You'll find a lot of sands, a lot of saprolite, and then a lot of compressed material. Looks very competent, and some of it we actually have to blast, but when you start to drive trucks over it in rainfall, it just really turns into mush. There's a lot about just getting through these upper layers, getting down to a firmer base and more competent material. That is the benefit of opening the pit up in the center, which is of that better pit. Typical conditions, as Michael mentioned, we've had to bring in heavier grader equipment. We've looked at ways to keep sumps active. It's not typical.
I've worked in some very wet mines in the frontier of, in the highlands of Peru. It's quite a bit different where the water can be trapped in long-term permanent sumps and rock and pumped out. We're mining through these benches, trying to sump into them, trying to connect the sumps, really just chasing around this perched water. It is quite a bit different than other sites that I have seen in extremely wet conditions. If you're pumping in [some certain state ], you can readily manage the water. In this case, in Haile, we spend quite a bit of time trying to chase it through these sand layers.
Okay. As time goes on, and you open the pit up more, you'll be more into the base, into the harder rock, and this will be less of an issue. Is that a fair statement?
That's correct. I think Michael brought it up previously. When we look at our longer term stage plan, and we actually look at our longer term pit plan, we're tracking the amounts of material in our block models by sands, by saprolite, by fill materials, and also by what we call competent rock. Right now, we're somewhere between, say, 60% - 70% competent rock. That will get up into the 80% past 2023, and then it remains fairly constant as you're down into the deeper areas of the pit. Obviously, we do expect this to improve in time.
Daniel, just adding to that, the advantage of going underground as well. The competent rock is relatively dry from our geological and hydrological drilling. Getting the underground up and running and then having a base production from underground of that 90,000 oz per year certainly assists. For us, that future is how do we expand that underground to continue that 90,000 oz a year of gold production for greater than five years and match the underground life to the open pit life. That's the potential that we see as well. That decouples the weather events from a great proportion of the mill feed.
Right. It sounds like there's a bit of a learning curve, though, just on the open pit, just in terms of going through this stuff, because it isn't standard. On the underground, the underground's obviously going to be almost 100% in the competent rock. Is that it?
That is correct, yes. 100% in the competent rock. That's right.
Great. Thanks very much, guys.
Thank you. Ladies and gentlemen, as a reminder, if you do have a question, please press star followed by one on your touchtone phone. Your next question will be from David Taylor at Taylor Asset Management. Please go ahead.
Hello. Hi there. I've got more of a statement than a question, but I'd love to hear your comments afterwards. I just start off by stating the obvious, that the performance, it's just been a complete disaster. This might be one of the worst performing gold stocks in the galaxy. I found it frustrating, your comment when somebody asked you about the Didipio, what happened, and your response was that the President has more things to worry about, like COVID. When I think about, I'm having a long-term shareholder, both institutionally and personally, and I think about different strategies here.
You could've either been proactive or reactive. Proactive strategies in the Philippines could have involved some of the things that Mick talked about in the past, like a dual listing or selling a piece of the asset to a local, or selling the asset outright, a local sponsorship, or local board members, having somebody influential on your side. You clearly didn't have the right people who didn't have the ear of the President's Office. Instead of being proactive, you guys were reactive, you relied on the courts. You always believed that the Philippines was a land of courts and land of laws, you lost at the local level, you lost at the provincial level. Now I sort of listen to what your strategy is, your only strategy is relying on the Supreme Court, you've lost at every court level.
Which to me, I think that's naive and it leads me to believe that there's more to it than COVID and the President having other things to worry about. I believe that the local governor, who's anti-mining or is looking for a bigger piece of the pie, had the ear of the President's Office. If your only strategy is relying on the Supreme Court, you're going to lose like you've lost at every single court level. I guess my question is, what are your alternative strategies here other than just relying on the courts where you've failed in the past?
Yeah, look, thank you for that, David. We are exceptionally frustrated with the process. The Court of Appeals and the Supreme Court process that we're looking at is really just about the injunction about the barricade. That doesn't have any impact on the FTAA. It was more about the injunction for a quick resolution to the barricade. We were planning to actually pull that from the Court of Appeals before the result, just due to the process, we sort of missed that window to do that. We're still considering that. We still have the major appeal through the regional court, basically on the validity, which is the initial case. That's something that we're still going through. We've got to the Office of the President, it has taken us a while, we're still with the Office of the President.
While we're still seeing positive action, with regards to that, we haven't had any sort of negative comments back. We're still in discussions with the government. We're still considering that as the pathway forward. We've had to make some difficult decisions with the workforce. We're not relying on the courts with regards to the FTAA. We're relying on the discussions with the President and the work that we've done and showing the government and the President that we're responsible gold miners. There is still activity there. It is still the first FTAA, and we're still working with the group to ensure that. We understand their frustrations because we're living with those frustrations every day. We understand the asset is a lot more valuable in our hands.
We have some definite trigger points to have a look at what else we need to do if things advance or don't advance. We'll be continuing to review those as we move forward. For us, the FTAA has been taken back down to the working group and has been recommended by all the departments. Department of Finance to the Mines and Geosciences Bureau and the Department of Environment and Natural Resources have all recommended us and the FTAA should be rolled over the same conditions.
That didn't happen. You have a letter from the finance minister that says you could operate without an FTAA, and that paper proved to be completely worthless.
Yeah. No, we had a letter from the Mines and Geosciences Bureau, not the Department of Finance.
Yeah. No. Well, I understand there is continued dialogue, but I guess if the President was to do something, he would have done it before you fired, basically, you let all the employees go. The fact that you pulled, I understand you pulled from the Appeals before there was a decision, but let's be honest, a year went by before the Appeals Court even They never even decided on the case.
Yeah. Look, that's correct. We're still working through, David, on it. For us, it's still in the state that we're still talking to the Executive Secretary in the department, the Executive Secretary's department. We're still sort of having positive engagement there. We're still working towards finalizing the FTAA and moving forward.
Okay, just my last question then. Other than you being a bunch of Australians trying to negotiate in the Philippines, maybe you can talk about who do you have senior standing in the Filipino community that is working on your behalf to get the ear of the President?
Yeah. We've got an internal resource, the President of OGPI in country. We're working with some of the congressmen and the governor of the supportive province. Working with those two or three people that have got a long sort of standing histories and great relationships with government officials.
Okay, thank you, and good luck.
Thank you.
There are no further questions at this time.
Operator, I do believe there's one more person queued up to ask a question.
Your next question comes from Paul Kaner with RBC Capital Markets. Please go ahead.
Yeah. Hi, Michael and team. Just a quick one from me. Just on your hedging profile, could you maybe just outline your strategy there and how many ounces you plan on hedging going forward, in the near term?
Yeah. Look, thanks, Paul. At the moment, I think we've got around about 29,700 oz hedged in New Zealand, at a NZD 2,000 put option. The rest have been the pre-sales, the two tranches of pre-sales. Historically, we've hedged just the Macraes ounces and to ensure that we have a good margin as we operate within Macraes. It has got a very low mining and milling dollar per ton rate, but a lower grade. It's really been to ensure that we get a return and a good margin from the Haile, the Macraes operation. That's probably the way that we look at hedging at this point in time, and we don't plan to sort of do any hedging in the future. We have to deliver into the gold pre-sales, as Scott had mentioned, and that's sort of been delivery in this quarter.
We pushed this quarter and then quarter two of next year.
Great. Thanks. That's it from me. Cheers.
There seem to be no further questions at this time. Please proceed.
That concludes our webcast and conference call. A replay will be available on our website later today. On behalf of Michael, Scott, Mark, Jim, and the rest of the team, thank you for joining us. Bye for now.
Ladies and gentlemen, this concludes your conference call and webcast for today. We thank you for participating and ask that you please disconnect your lines. Have a great day.
