Hello and thank you for joining us for I-80 Gold's 2024 fourth quarter conference call and webcast. (Operator Instructions)
Thank you. Before we begin, please note that some of today's comments may contain forward-looking statements which involve risks and uncertainties. Actual results could differ materially. I ask everyone to view slide 2 of the slide presentation, which is available on I-80 Gold's website, to view the cautionary notes regarding forward-looking statements made on this call and the risk factors related to these statements.
Today's speakers include Richard Young, Chief Executive Officer of I-80 Gold; and Matt Gili, President and Chief Operating Officer; and Ryan Snow, Chief Financial Officer. Following today's formal presentation, we will open the call to your questions. Now, over to Richard.
Richard Young - Chief Executive Officer, Director
Thank you, operator, and good morning, everyone. Moving to slide 4. During the fourth quarter, we announced a new development plan for our portfolio of three underground and two open pit gold projects.
In February and early March, we released summarized key operating and financial terms for each of our five projects. We have now filed the preliminary economic assessments for those five goal projects. However, you will not see on our website five PEAs.
Under both Canadian and US regulation, you can only have one preliminary economic assessment per property. So we've combined both the open pit and underground at Granite Creek into one technical report; Ruby Hill, which includes Archimedes, and Mineral Point is a second; the third is Cove; and the fourth tech report covers off Lone Tree, which includes our large gold resource, which is currently not in our development plan; and then the process facilities including the autoclave refurbishment.
So because we're now a US registrant, we have to file these tech reports under both US and Canadian regulations. So over the past 12 hours we have filed four S-K 1300s as required under United States regulations, as well as four NI 43-101 reports as required under Canadian regulations.
The US reports are available on EDGAR, and the Canadian reports are available under SEDAR+. Now, the key operating and financial terms are identical across both regulatory frameworks. The forms of the reports are largely similar apart from a few minor changes or differences.
Updating the PEAs was a positive step in three respects. First, Improving our disclosure and clarity around our development plan. And second, highlight the potential value of the portfolio. And third, it's pivotal as we put together our recapitalization plan. I want to congratulate the technical team for completing the work in such a short period of time.
The new life of mine plans for each project have allowed us to define an executable strategy with a clear path towards producing half a million ounces of gold by the early 2030s. And it's clarified the capital requirements and demonstrated the significant value that's embedded across our gold portfolio. At our March 6 Investor Day, the team also underscored the extensive untapped value across that portfolio.
In summary, we have a pipeline of new projects to permit bring online over the next five or six years. We're confident the activities can be staging -- staggered and are manageable. We believe the cash flow models that have been presented in these initial studies are achievable and expect them to further improve with the work the team will complete in between now and the anticipated release of the feasibility studies later this year and early next year.
Moving to slide 5. Life of mine valuations based on the recent published PEAs for all projects are shown at both our reported gold price assumption of $2,175 per ounce, as well as at $2,900 per ounce. Combined, these projects indicate a combined net present value of $1.6 billion at $2,175 per ounce and $4.5 billion based on $2,900 per ounce.
As we discussed in our Investor Day, these studies represent the base case scenario. With (inaudible) we expect to increase the value of these projects through additional drill programs aimed at extending the mine lives. A strategic change to our development plan was the addition of the autoclave refurbishment. Driven by changes to our existing coal milling agreements, the long-term potential value of our Granite Creek Underground project, and the simple economics of the autoclave, the anticipated capital spend for the refurbishment is now included in the recapitalization plan.
Turn to slide 6. As discussed on our Investor Day, the decision to include the autoclave refurbishment in the development plan changed the recapitalization timeline. The shift until the refurbishment study is complete in the second half of this year. Management is advancing its recapitalization plan to support the company's development plan on several fronts.
And we are in active discussions with several parties regarding a number of financing options, including a senior debt facility, royalty sales, non-core asset sales such as our FAD property, a working capital facility, as well as terming out the 2025 quarterly gold pre-pays.
Our CFO, Ryan Snow, will expand on our new National Bank agreement regarding the March 2025 pre-pays and the new working capital facility we're currently finalizing. In order to execute and put in place a senior debt facility, feasibility studies will be required for three of the five gold projects, as well as the class three engineering study for the autoclave refurbishment.
Further, certain additional work may be requested by a potential lending syndicate on the two gold projects not yet advanced to the feasibility stage to further de-risk these projects.
Lending parties intend to review the technical studies that we filed over the last 12 hours. Any additional work required to complete the technical due diligence could increase costs or push out completion of the feasibility studies. However, we do not expect a material increase in cost or time. The goal is to have a new senior financing in place for the second quarter of 2026.
With that, I'll now pass it over to Matt for an operations update. Matt.
Matthew Gili - President, Chief Operating Officer
Thank you, Richard, and hello everyone. As we do with all our operations meetings, I will begin with our number one priority here on slide 7, which is safety. We finished the year with a last time injury frequency rate of 1.27. Our safety performance improved dramatically during the course of the year, and I'm proud of the team's absolute focus on ensuring everyone working at our property returns home safe and healthy every day.
Regarding environmental compliance, we maintained our clean record by ending our fourth consecutive year without any environmental violation notices from our regulators. And to emphasize this point, I-80 Gold has never received an environmental notice since the company's 2021 inception.
Turning to 2024 production results on slide 8. At Granite Creek Underground, we mined approximately 38,000 ounces of contained gold, or 71% of our internal target, and produce just above 16,000 ounces of gold after applying the appropriate payability factors and including stockpile build up at the end of this year.
However, the high-grade oxide and sulfide production was 60% lower than planned but partially offset by unbudgeted low grade oxide material mined and processed at our heap leach facilities at Lone Tree. Mining rates and gold production at Granite Creek were impacted by higher than anticipated rates of water ingress to the bottom of our workings, which delayed our progress on the main decline and prevented us from reaching and developing additional mineralization zones as planned.
Currently all components of our dewatering system are permanent, functioning, and in operation. The amount of contact water removed from the underground workings is gradually declining from an average of 1,400 gallons per minute in January of 2025 to approximately 1,200 gallons per minute over the first half of March 2025. Which is in line with our newly implemented predictive model.
With these improvements we are seeing in managing water, we are pleased to report that we have recommenced advancing the main decline. And both our decline advance rate and our overall mining rate of the contained analysis are on plan for the first quarter of 2025.
Additional dewatering upgrades will be completed in 2025, and production rates are expected to ramp up to a steady state in the second half of this year, 2025. Production from our two existing heap leach operations exceeded our internal targets for 2024. With approximately 6,200 ounces produced from Lone Tree, and 3,700 ounces produced for Ruby Hill. Both historic leach pads are in their final phase of extracting any remaining gold from the material that was placed on them several years ago.
Looking ahead, we expect to produce between 30,000 and 40,000 ounces of gold in 2025. Whereby Granite Creek Underground is expected to contribute between 20,000 to 30,000 ounces of gold, and the heap leach operations at Ruby Hill and Lone Tree are expected to contribute approximately 10,000 ounces of gold.
Now for an update on construction at Archimedes Underground on slide 9. Underground permitting activities continued in the fourth quarter, and we received the record of decision from the Bureau of Land Management to commence the underground portals in the first quarter of 2025. We expect to have associate state permits in hand in the second quarter of this year.
During the fourth quarter of 2024, we initiated construction of the surface facilities here at the high wall and have begun service works for installation of utilities and construction of a shop facility to commence portalling activities in the third quarter.
We expect to begin underground construction in the third quarter of this year in line with the recently published PEA. Archimedes Underground is expected to be the company's second underground mine and contribute to production at the end of 2026 or in early 2027.
Moving to slide 10. Permitting activities across our remaining properties with a [drilling] continues across the remaining properties with a 2025 focus on: Archimedes Underground, initiating permitting for an Environmental Impact Statement at Cove, and commencing the application process for both the Granite Creek open pit and the Mineral Point open pit projects. We have a highly experienced permitting team with a proven track record in the Nevada region.
Turning our attention to the technical team, a priority for this group through the course of 2025 is to bring the Granite Creek Underground and open pit, as well as Cove to the feasibility stage, and to publish a class three engineering study for the Lone Tree autoclave refurbishment.
With the technical reports recently filed, we believe potential providers of capital now have a clear view of these projects. Enabling them to assess these projects in detail and identify areas for improvement as we progress towards the feasibility stage. This will help you with the projects from a lender's perspective as we work to complete our recapitalization plan, as Richard mentioned earlier.
Additionally, we are considering the possibility of advancing Mineral Point to the preliminary feasibility stage in the first half of 2026 to also assist in de-risking the project from a lending perspective.
As Richard also mentioned, we believe I-80 Gold's updated development roadmap towards producing a target of 400,000 to 500,000 ounces per year by the early 2030s is staggered and manageable. And we expect to see improved economics as we move towards the feasibility stage.
Looking at exploration on slide 11. In 2024 we drilled over 100,000 ft, mainly at Granite Creek and Cove. Our 2025 drill program is modest and strategically focused to ensure maximum impact. At Granite Creek, we will be finalizing the infill drilling program to support advancing the Granite Creek underground to feasibility, and to study the step out of the South Pacific Zone along strike to the northeast.
Drilling was paused in 2024 and anticipated to resume once the underground exploration drift is completed in 2025. At Cove, the planned infill drilling is now complete, and the results will be used to advance the feasibility study.
Finally, at Ruby Hill, we are completing some infill drilling within the upper zones of the Archimedes Underground in preparation for mining. As well as completing some infill drilling at Mineral Point, both for resource confirmation, geotechnical, geochemical, and metallurgical data to initiate permitting on this project and the PFS. This program is focused on confirming existing work and advancing technical reports. We have deferred true exploration to future years when more discretionary funding is available.
That concludes my operations update. I'll now hand over to Ryan for a financial review.
Ryan Snow - Chief Financial Officer
Thank you, Matt, and good morning, everyone. Starting with slide 12 to discuss the change in our financial reporting.
As of January first, 2025, we're reporting with the US Securities Exchange Commission as a domestic filer. And therefore, have transitioned from International Financial Reporting Standards, or IFRS to US Generally Accepted Accounting Principles otherwise known as US GAAP. This change was made retrospectively with our 2024 financial statements, and all comparatives were restated accordingly. You can find the 2024 year-end statements and the first three quarters of 2024 with comparative periods filed on EDGAR, SEDAR+, and on the company's website.
Going forward, certain pre-development costs, which were previously capitalized under IFRS will be recorded through the income statement as an expense under US GAAP until mineral reserves are declared. The main transition adjustments include a capitalization reversal of $80 million for underground development work at Granite Creek and Cove, expensed retrospectively between 2022 to 2024.
A decrease to reclamation liabilities and assets of approximately $16 million due to the inclusion of third-party markup under US GAAP more than offset by a higher discount rate. A transition adjustment related to our convertible debentures resulted in a reclass of $13.8 million from the equity section of our balance sheet to the non-current liability section.
And lastly related to the Paycore acquisition, a deferred tax liability of $13.5 million was recorded due to an IFRS exemption not available under US GAAP. This is a result of the purchase price being higher than the tax bases at the time of acquisition. Additionally, the 10-K will serve as I-80 Gold's primary disclosure document moving forward, and the company will no longer file an AIF.
Turning to slide 13. Gold sales totaled approximately 9,050 ounces for the fourth quarter and 21,500 ounces for the year. This reflects the impact of the water issues at Granite Creek that Matt outlined earlier. Total revenue from gold and silver sales was approximately $23 million and $50 million for the fourth quarter and full year period respectively. And slightly lower than the prior year period due to lower volumes sold, partially offset by a higher average realized gold price.
Additionally, gold sales were impacted by working capital timing, as at the end of 2023, the company pre-sold stockpiled material, and during 2024, the company rebuilt that stockpile balance.
We concluded both the quarter and the full year period in a net loss position due to the ongoing development of our projects. The majority of our growth expenditures for both the 3- and 12-month periods were allocated to infill drilling and pre-development activities. And we expect this to be the case for the next several quarters as we continue to advance drilling and technical work. Overall, we've been managing mining costs well during the impacted underground advancement rates at Granite Creek.
Moving to slide 14. To support our development strategy during the fourth quarter and early 2025, we undertook several financing initiatives as we continue to focus on the best way to secure capital to advance our development plans. These steps have allowed us to better manage liquidity, support our near-term development goals, and execute on our refinancing plan.
Most recently, we entered into two financial arrangements to enhance near-term liquidity and balance sheet flexibility. On March 31, the company entered into a new gold and silver purchase agreement with National Bank of Canada, under which National Bank purchased approximately 6,800 ounces of gold and 345,000 ounces of silver from the company for delivery by September 30, 2025, or earlier upon an infusion of capital.
The proceeds will be used to satisfy all outstanding gold and silver delivery obligations due to Orion on March 31. The company is also finalizing a working capital facility for up to $12 million with Auramet International maturing in 12 months. We are confident this path will lead to securing senior financing, allowing us to transition away from convertible debt in favor of lower cost, less dilutive financing.
In addition, in the short term, the company plans to meet its liquidity requirements by deferring non-essential costs until such time as additional capital is sourced. We expect our cash position to be approximately $25 million following the end of the first quarter of 2025. We believe that securing new agreements with National Bank and Auramet highlights the growing confidence in the properties, reflecting the positive impact of the preliminary studies completed.
Within the studies, we highlight three key areas where we plan to focus our growth expenditures over the next three years to support the company's broader development strategy. These expenditures are discretionary and will depend upon available liquidity, but in terms of priority, they are as follows. First, advancing our permitting activities, this is our top priority. Second, investing in feasibility studies to move projects forward with greater clarity. And third, continuing development work at Archimedes Underground.
We expect total growth expenditures in support of these three initiatives to range between $40 million and $50 million in 2025.
With that, I will now turn the call back over to Richard.
Richard Young - Chief Executive Officer, Director
Well, thank you, Ryan. Thank you, Matt. And at this time, we'll now turn the call over to the operator for questions.
Operator
Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. (Operator Instructions)
There are no questions at this time. I will now turn the call over to Richard for closing remarks.
Richard Young - Chief Executive Officer, Director
Well, thank you, operator. Just a couple things I want to highlight on. I know that the market is awaiting the recapitalization plan. It is well underway. I think that the National Bank agreement that we've now put in place is a step in that direction along with Auramet. And that's really a testament to the quality of the tech reports that have been filed and the value they see.
There's continued work to be done, but the team's got its head down and we're looking to execute. We are excited about the next chapter in I-80 Gold's future. As we progress those PEAs towards the feasibility stage as we strengthen our balance sheet to develop our pipeline project. So, I'd like to thank everyone for their time today, and we are available to answer any questions that you might have offline.
Thank you. Have a great day. Bye now.
Operator
Ladies and gentlemen, this concludes your conference call for today. We thank you for participating and ask that you please disconnect your lines.
