Q1 2024 Financial Results

Atalaya Mining Plc (LSE: ATYM) is pleased to announce its unaudited first quarter financial results for the period ended 31 March 2024 ("Q1 2024" or "the Period") together with its unaudited condensed consolidated financial statements.

Highlights

• Copper production of 10.7 kt Cu at cash costs of $2.99/lb and AISC of $3.17/lb

‒ Good cost control despite lower production in Q1 2024

• EBITDA of €10.3 million at a realised copper price of $3.89/lb

‒ Lower operating costs partly offset lower copper revenues

• Made further investments in key projects including waste stripping at San Dionisio
• Strong balance sheet maintained with €36.1 million in net cash

‒ Negative working capital movements impacted operating cash flows

• Completed move to Main Market of the London Stock Exchange on 29 April 2024

‒ Re-domiciliation work continues post implementation of new Cyprus law

Q1 2024 Financial Results Summary

• Includes restricted cash and bank borrowings at 31 March 2024 and 31 March 2023.

Alberto Lavandeira, CEO, commented:

"Naturally, our revenues reflected our copper production for the quarter and while lower than recent periods, we expect copper grades to improve in the coming quarters. Positively, our cost control was good and helped to support EBITDA in Q1 2024, and our net cash position remains strong. Waste stripping activities are also advancing at San Dionisio, which is expected to provide Riotinto with higher grade material in the coming years.

The positive developments in the copper price have been pleasing to observe in recent weeks. Global demand remains supported by solid economic activity and strong investment in renewables, new technologies and domestic supply chains. On the supply side, challenges remain in the largest copper producing regions.

Few new large sources of supply are expected in the coming years as a result of permitting and execution challenges, discipline by key producers and a preference for buying production capacity rather than building it, as highlighted by recent corporate activity.

Atalaya is well-positioned thanks to its pipeline of growth projects that are located in regions with high quality infrastructure and long mining histories. Our key projects including Touro and those around Riotinto are expected to have low capital intensities and could come onstream much quicker than the mega projects being pursued by peers."

Q1 2024 Operating Results Summary

Mining

Ore mined was 3.7 million tonnes in Q1 2024 (Q1 2023: 3.4 million tonnes).

Waste mined was 5.5 million tonnes in Q1 2024 (Q1 2023: 6.5 million tonnes). Separately, waste stripping activities advanced at the San Dionisio area.

Processing

The plant processed ore of 3.7 million tonnes during Q1 2024 (Q1 2023: 3.7 million tonnes). Throughput in Q1 2024 included the scheduling of two plant shutdowns, one for maintenance and the other for connecting the 50 MW solar plant to the substation.

Copper grade was 0.34% in Q1 2024 (Q1 2023: 0.38%). The lower copper grade in Q1 2024 was mainly the result of pit sequencing and also due to rainfall which prevented access to higher grade areas of the Cerro Colorado pit.

Copper recovery was 84.74% in Q1 2024 (Q1 2023: 86.88%) due to lower grades being processed.

Production

Copper production was 10,666 tonnes in Q1 2024 (Q1 2023: 12,139 tonnes). Lower production in Q1 2024 was mainly the result of lower grades and recoveries.

On-site copper concentrate inventories at the end of Q1 2024 were approximately 8,283 tonnes.

Copper contained in concentrates sold was 10,286 tonnes in Q1 2024 (Q1 2023: 12,501 tonnes).

Cash Costs and AISC Breakdown

Note: Some figures may not add up due to rounding.

Cash costs were $2.99/lb payable copper in Q1 2024 (Q1 2023: $2.88/lb), with the increase mainly due to lower copper production, partly offset by lower offsite costs.

AISC were $3.17/lb payable copper in Q1 2024 (Q1 2023: $3.12/lb). Lower capitalised stripping costs at Cerro Colorado helped to offset higher cash costs and corporate costs. AISC excludes one-off investments in the tailings dam (consistent with prior reporting) and waste stripping at the San Dionisio area.

Q1 2024 Financial Results Highlights

Income Statement

Revenues were €69.9 million in Q1 2024 (Q1 2023: €91.2 million). Lower revenues were the result of lower copper concentrate sales and lower realised copper prices.

Operating costs were €59.7 million in Q1 2024 (Q1 2023: €66.8 million). Lower operating costs were mainly the result of lower sales volume and lower electricity prices.

EBITDA was €10.3 million in Q1 2024 (Q1 2023: €24.4 million). Lower EBITDA resulted from lower revenues, partly offset by lower operating costs.

Profit after tax was €1.6 million in Q1 2024 (Q1 2023: €11.1 million) or 1.5 cents basic earnings per share (Q1 2023: 8.1 cents). Lower profits were impacted by the same factors as EBITDA and higher depreciation, partly offset by a foreign exchange gain and lower taxes.

Cash Flow Statement

Cash flows from operating activities before changes in working capital were positive €11.4 million in Q1 2024 (Q1 2023: positive €24.1 million) and net cash from operating activities was negative €1.7 million (Q1 2023: positive €12.4 million).

Cash flows used in investing activities were €17.9 million in Q1 2024 (Q1 2023: €8.8 million). Key investments in Q1 2024 included €0.4 million in sustaining capex (Q1 2023: €0.3 million), nil in capitalised stripping at Cerro Colorado (Q1 2023: €1.9 million), €8.2 million related to the San Dionisio area (Q1 2023: nil), €2.3 million to extend the tailings dam (Q1 2023: €2.3 million), €0.7 million for the 50 MW solar plant (Q1 2023: €1.6 million) and €6.3 million for the E-LIX Phase I Plant (Q1 2023: €3.3 million) including ramp-up costs.

Cash flows from financing activities were negative €16.8 million in Q1 2024 (Q1 2023: negative €9.4 million) due to repayments made under the Company's credit facilities.

Balance Sheet

The Company's balance sheet remains strong with consolidated cash and cash equivalents of €86.2 million as at 31 March 2024. Net of current and non-current borrowings of €50.1 million, net cash was €36.1 million as at 31 March 2024, compared with €54.3 million as at 31 December 2023 with the decrease in cash being the result of lower copper sales and higher investment in the Company's capital projects.

Inventories of concentrate valued at cost were €8.8 million at 31 March 2024 (31 December 2023: €8.4 million). The total working capital surplus was €59.6 million at 31 March 2024 (31 December 2023: €68.6 million).

Outlook for 2024

Copper production in Q1 2024 was impacted by lower copper grades and recoveries. Guidance for FY2024 of 51,000 - 53,000 tonnes is unchanged due to the expectation of higher copper grades in the coming quarters and will be reviewed on an ongoing basis.

Guidance for FY2024 cash costs and AISC are $2.80 - 3.00/lb and $3.00 - 3.20/lb copper payable, respectively. AISC excludes one-off investments in the tailings dam and ongoing waste stripping at the San Dionisio area.

Corporate Activities Update

Move to the Main Market

On 29 April 2024, the Company announced the admission of its ordinary shares to the premium listing segment of the Official List maintained by the FCA and to trading on London Stock Exchange's main market for listed securities, along with the cancellation of trading on AIM.

The move up marks a significant corporate milestone for Atalaya and reflects the Company's desire to expand its investor base and continue its growth trajectory.

Re-domiciliation

On 12 December 2023, the Company held an Extraordinary General Meeting in relation to its intention to re-domicile the Company by transferring its registered office from the Republic of Cyprus to the Kingdom of Spain. All resolutions were approved by the Company's shareholders.

On 15 March 2024, a new law related to cross-border reorganisations entered into force in Cyprus, thereby amending the Cyprus Companies Law by setting out new procedural requirements in connection with cross-border conversions of Cypriot companies into another EU jurisdiction. The Company has concluded that it will need to follow the new procedures in order to complete the re-domiciliation.

As part of the new law, the Company is required to publish a report that analyses the implications of the cross-border conversion for its shareholders and employees ("Cross-Border Conversion Report"). The Cross-Border Conversion Report is now available on the Company's website at www.atalayamining.com/investors/other-documents/.

The Company will seek the shareholder approvals required to implement the new procedures at its 2024 Annual General Meeting on 27 June 2024. Assuming all necessary approvals are obtained, the Company expects that it could complete the re-domiciliation procedures in Q4 2024. Further updates on the process will be provided by the Company in due course.

Asset Portfolio Update

Proyecto Riotinto

In 2023, the Company was granted a substantial modification to the existing Unified Environmental Authorisation (or in Spanish, Autorización Ambiental Unificada ("AAU")) for Proyecto Riotinto by the Junta de Andalucía. The AAU allows for the expansion of tailings capacity and the mine footprint at Riotinto and represents an important step towards developing regional deposits such as San Dionisio and San Antonio.

The Company is advancing the permitting process associated with the San Dionisio final pit, which represents a key component of the integrated mine plan outlined in the 2023 Riotinto PEA. Waste stripping is underway in order to prepare the area for future mining phases, with 4.6 million tonnes of waste mined in Q1 2024. Additional mining equipment is expected to arrive on site in Q2 2024.

At San Antonio, preparations are underway to begin an infill and step-out drilling programme.

E-LIX Phase I Plant

Final construction activities are underway at the E-LIX Phase I plant. Following the production of initial copper cathodes and zinc precipitate, commissioning and ramp-up is expected to continue throughout Q2 2024.

50 MW Solar Plant

Construction activities are advancing at the 50 MW solar plant at Riotinto, however, the Company's contractor has given notice of further delays and now expects completion in late 2024.

The Company is evaluating further measures that could mitigate the financial impact of a future increase in market electricity prices until the 50 MW solar plant is fully completed. So far in 2024, market electricity prices have been below long term averages in Spain, therefore the construction delay has not had a material impact on the Company's operating costs.

Riotinto District - Proyecto Masa Valverde ("PMV")

In 2023, the Company was granted the AAU and exploitation permit for PMV. As a result, various workstreams continue including geotechnical and sterilisation drilling to support design work associated with a future ramp and ventilation shaft. At this stage, the Company expects to start construction of the access ramp by the end of 2024.

Two core rigs are active and focused on step-out drilling at the Mojarra Trend and the Masa Valverde deposit.

Proyecto Touro

Touro has the potential to become a new source of copper production for Europe. As such, the project could also be granted "Strategic Project" status by the EU, which can be awarded to projects "based on their contribution to the security of supply of strategic raw materials, their technical feasibility, sustainability and social standards", as part of the Critical Raw Materials Act. Copper was added to the list of "Strategic Raw Materials" owing to its importance for strategic sectors and technologies and due to the supply-demand imbalance that is expected in the near future.

Proyecto Ossa Morena

Drilling continued to progress with one rig at the Guijarro-Chaparral gold-copper project and the La Hinchona copper-gold project, both in the central part of the district. Drilling is expected to resume at the flagship Alconchel-Pallares copper-gold project during Q2 2024.

Proyecto Riotinto East

In Q2 2024, drill testing will begin at priority anomalies identified via SkyTEM and AGG surveys.

Incorporation and description of the Business

The Company was first listed on the Alternative Investment Market (AIM) of the London Stock Exchange in May 2005, trading under the symbol ATYM. On 29 April 2024, the Company was admitted to the premium listing segment of the Official List maintained by the FCA and to trading on the main market of the London Stock Exchange.

Proyecto Riotinto

Proyecto Touro

In November 2019, Atalaya executed the option to acquire 12.5% of Explotaciones Gallegas del Cobre, S.L. the exploration property around Touro, with known additional reserves, which will provide high potential to the Proyecto Touro.

Proyecto Masa Valverde

On 21 October 2020, the Company announced that it entered into a definitive purchase agreement to acquire 100% of the shares of Cambridge Mineria España, S.L. (since renamed Atalaya Masa Valverde, S.L.U.), a Spanish company which fully owns the Masa Valverde polymetallic project located in Huelva (Spain). Under the terms of the agreement Atalaya will make an aggregate €1.4 million cash payment in two instalments of approximately the same amount. The first payment is to be executed once the project is permitted and second and final payment when first production is achieved from the concession.

Proyecto Ossa Morena

In December 2021, Atalaya announced the acquisition of a 51% interest in Rio Narcea Nickel, S.L., which owns 9 investigation permits. The acquisition also provided a 100% interest in three investigation permits that are also located along the Ossa- Morena Metallogenic Belt. In Q3 2022, Atalaya increased its ownership interest in POM to 99.9%, up from 51%, following completion of a capital increase that will fund exploration activities. During 2022 Atalaya rejected 8 investigation permits.

Atalaya will pay a total of €2.5 million in cash in three instalments and grant a 1% net smelter return ("NSR") royalty over all acquired permits. The first payment of €0.5 million will be made following execution of the purchase agreement. The second and third instalments of €1 million each will be made once the environmental impact statement ("EIS") and the final mining permits for any project within any of the investigation permits acquired under the Transaction are secured.

Proyecto Riotinto East

In December 2020, Atalaya entered into a Memorandum of Understanding with a local private Spanish company to acquire a 100% beneficial interest in two investigation permits (known as Peñas Blancas and Cerro Negro investigation permits), which are located immediately to the east of Proyecto Riotinto.

Overview of Operational Results

Three months operational review

Mining

Waste mined was 5.5 million tonnes in Q1 2024 (Q1 2023: 6.5 million tonnes), compared with 7.4 million tonnes in Q4 2023. Separately, waste stripping activities advanced at the San Dionisio area.

Processing

The plant processed 3.7 million tonnes of ore in Q1 2024 (Q1 2023: 3.7 million tonnes) compared to 4.1 million tonnes in Q4 2023. Throughput was impacted by the scheduling of two plant shutdowns, one for maintenance and the other for the connection of the 50 MW solar plant to the substation.

Copper grade in Q1 2024 was 0.34% (Q1 2023: 0.38%) compared to 0.36% in Q4 2023. The lower copper grade in Q1 2024 was mainly due to pit sequencing and also rainfall which prevented access to higher grade areas of the Cerro Colorado pit.

Copper recovery was 84.74% in Q1 2024 (Q1 2023: 86.88%), compared with 85.47% in Q4 2023, due to lower grades being processed.

Production

Copper production was 10,666 tonnes in Q1 2024 (Q1 2023: 12,139 tonnes), compared with 12,775 tonnes in Q4 2023. Lower production in Q1 2024 was mainly the result of lower grades and recoveries.

On-site copper concentrate inventories at the end of Q1 2024 were approximately 8,283 tonnes.

Copper contained in concentrates sold was 10,286 tonnes in Q1 2024 (Q1 2023: 12,501 tonnes).

Outlook

Operational guidance

Guidance for Proyecto Riotinto is unchanged from the previously announced outlook.

Production

Copper production in Q1 2024 was impacted by lower copper grades and recoveries. Guidance for FY2024 of 51,000 - 53,000 tonnes is unchanged due to the expectation of higher copper grades in the coming quarters and will be reviewed on an ongoing basis.

Operating Costs

Operating cost guidance for FY2024 are a cash cost range of $2.80 - 3.00/lb copper payable and an AISC range of $3.00 - 3.20/lb copper payable. AISC excludes one-off investments in the tailings dam (consistent with prior reporting) and waste stripping at the San Dionisio area, which are included in capital expenditure guidance below.

Capital Expenditures

Non-sustaining capital expenditure guidance for FY2024 is €64 - 73 million. This includes €4 - 5 million for completion of the 50 MW solar plant, €5 - 7 million for completion and ramp-up of the E-LIX Phase I Plant, €42 - 46 million for San Dionisio waste stripping, dewatering and road relocation and €13 - 15 million for expansion of the existing Riotinto tailings facility.

Exploration

Atalaya's exploration guidance for FY2024 is €5 - 7 million.

Overview of the Financial Results

The following table presents summarised consolidated income statements for the three months ended 31 March 2024, with comparatives for the three months ended 31 March 2023.

Three months financial review

Revenues for the three-month period ended 31 March 2024 amounted to €69.9 million (Q1 2023: €91.2 million). Lower revenues are mainly due to a lower in copper concentrate volume sold and lower realised copper prices.

Realised prices excluding QPs were US$3.89/lb copper during Q1 2024 compared with $4.00/lb copper in Q1 2023. The realised price, including QPs were approximately $3.79/lb during the quarter ($3.94/lb in Q1 2023).

Cost of sales for the three-month period ended 31 March 2024 amounted to €56.8 million, compared with €63.0 million in Q1 2023. Lower costs primarily attributable to lower sales volume and reduced electricity prices.

Cash costs of $2.99/lb payable copper during Q1 2024 compared with $2.88lb payable copper in the same period last year. Higher cash costs mainly due to lower copper production in the quarter, combined with a weaker USD Dollar/Euro exchange rate compared to Q1 2023. AISC excluding investment in tailings dam expansion and San Dionisio stripping for Q1 2024 were $3.17/lb payable copper compared to $3.12/lb payable copper in Q1 2023. The increase was primarily due to higher cash costs.

Sustaining capex for Q1 2024 amounted to €0.4 million compared with €0.3 million in Q1 2023. Sustaining capex was mainly related to continuous enhancements in the processing systems of the plant. In addition, the Company invested €2.3 million in the project to increase the tailings dam during Q1 2024.

Capex associated with the construction of the 50 MW solar plant amounted to €0.7 million in Q1 2024, while investments in the E-LIX Phase I plant, commissioning and ramp-up totalled €6.3 million. Additionally, a capex of €8.2 million is related to the San Dionisio area.

Administrative and other expenses amounted to €1.9 million (Q1 2023: €2.0 million) and include non-operating costs of the Cyprus office, corporate legal and consultancy costs, on-going listing costs, officers and directors' emoluments, and salaries and related costs of the corporate office.

Exploration costs for the three-month period ended 31 March 2024 amounted to €0.9 million, lower than Q1 2023 (€1.5 million).

EBITDA for the three months ended 31 March 2024 amounted to €10.3 million compared with Q1 2023 of €24.5 million. The lower EBITDA was due to the decline in sales as explained above, partially offset by a reduction in cost of sales.

The main item below the EBITDA line is depreciation and amortisation of €9.6 million (Q1 2023: €8.8 million).

Net foreign exchange differences have a positive impact due to the weaker US Dollar/Euro rate at the end of Q1 2024 compared with the beginning of the quarter.

Net financing costs for Q1 2024 amounted to €0.1 million compared with €0.8 million in Q1 2023.

Copper prices

The average realised copper price (excluding QPs) decreased 3% from US$4.00 per pound in Q1 2023 to US$3.89 per pound in Q1 2024.

The average prices of copper for the three months ended 31 March 2024 and 2023 are summarised below:

Realised copper prices for the reporting period noted above have been calculated using payable copper and excluding both provisional invoices and final settlements of quotation periods ("QPs") together. The realised price during the year, including the QP, was approximately $3.79/lb.

• Non-GAAP Measures
• Liquidity and Capital Resources

The following is a summary of Atalaya's cash position as at 31 March 2024 and 31 December 2023 and cash flows for Q1 2024 and 2023.

Liquidity information

Includes borrowings

Unrestricted cash and cash equivalents (which include cash at both Group level and Operation level) as at 31 March 2024 decreased to €86.2 million from €121.0 million at 31 December 2023. The decrease in cash was mainly due to higher cash outflows from operations, investments and repayment of financing. Specifically, negative working capital movements offset cash flows from operations, investments increased due to the capital expenditure in the San Dionisio area and financing saw higher outflows due to the repayment of operating facilities. Cash balances are unrestricted and include balances at operational and corporate level.

As of 31 March 2024, Atalaya reported a working capital surplus of €59.6 million, compared with a working capital surplus of €68.6 million at 31 December 2023. The decrease in working capital mainly resulted from the repayment of current payables.

Overview of the Group's cash flows

Three months cash flows review

Cash and cash equivalents were €86.2 million at 31 March 2024. This was due to the net results of cash used in operating activities amounting to €1.7 million, the cash used in investing activities amounting to €17.9 million, the cash used from financing activities totaling €16.8 million and net foreign exchange differences of positive €1.6 million.

Cash generated from operating activities before working capital changes was €11.4 million. Trade receivables in the period increased by €2.7 million, inventory levels increased by €2.2 million and trade payables decreased by €6.2 million.

Investing activities during the quarter consumed €17.9 million, relating mainly to the tailings dams project, E-LIX, San Dionisio area and continuous enhancements in the processing systems of the plant.

Financing activities during the quarter used €16.8 million driven by repayments of existing unsecured credit facilities.

Foreign exchange

During the three months ended 31 March 2024, Atalaya recognised a foreign exchange gain of €1.6 million (€1.2 million foreign exchange loss in Q1 2023). Foreign exchange gain mainly related to change in the period end EUR and USD conversion rates, as all sales are cashed and generally held in USD.

The following table summarises the movement in key currencies versus the EUR:

Sustainability

Corporate Social Responsibility

The first quarter of the year brings further developments from Atalaya and its wholly owned Fundación Atalaya Riotinto that continue to work on several actions to undertake its social responsibilities.

In this regard, the agreements with near-by municipalities to establish collaboration have been renewed and will be operative until mid 2027. With such instrument in place, there are already some agreed initiatives to improve certain aspects of the towns, with projects that will be funded by our Foundation Atalaya aiming at activities that will positively impact social, environmental, and infrastructure issues.

For example, during the quarter, Atalaya has agreed to fund the construction of a playground in Nerva, not only aimed at children but also comprising cardio exercising equipment for adults. Also in Nerva, Atalaya has agreed to fund the replacement of halogen bulbs for LED in multiple streets in Nerva town, which will improve the public lighting and contribute to reduce the carbon footprint of the town. In parallel, Atalaya keeps developing its own projects, including the Fourth Atalaya Mining Operators Course for unemployed locals. This program has entered now its final stage, with students already on board with the different companies to complete their 200 hrs hands-on training.

The Foundation is also working in the development of Riotinto Experience program, which is an established site tour open to the public that will represent a new product to attract visitors to the area contributing to diversification as well as a very effective channel to communicate the positive impact of modern mining. During the period, Fundación Atalaya has also agreed to support various initiatives in the near-by towns, including sporting activities, such as a bicycle championship that brought more than 400 participants (La Mina Bike Maraton), and contributions to local sports teams like CD Trail El Campillo, Campofrío FC, Riotinto Balompié, and Corta Atalaya Golf Club. It also contributed to cultural initiatives like the Music School "Julia Hierro" Contest, the Jornadas Micológicas with Agaricus association and the national Poetry Contest in Riotinto "Huellas de Cobre". On the social side, Atalaya has contributed to the activities of Unidos por el Alto association, which works with disadvantaged local youth.

Health and Safety

The positive trend of 2023 has continued during the first quarter of 2024. There were 3 accidents with lost time with a 5.08 for the Frequency Index and 0.07 for the Severity Index.

Annual reports of technical specialties in occupational risk prevention, the prevention plan, and the safety and health document accompanying the Work Plan were prepared, as well as the planning of preventive activity for the year 2024.

Regarding Industrial Hygiene measurements, almost all of those planned for the first quarter were carried out. As for the first intervention brigade, training for the volunteers of the Brigade in the handling of the basic life support and a inspection session of the mining facility.

In addition, Atalaya has reviewed the risks assessment of all jobs in terms of manual handling of loads, forced postures and repetitive movements to re-evaluate the ergonomics parameters.

Furthermore, during the quarter the first meeting of the health and safety committee with the worker representatives took place and Atalaya updated its internal procedure for controlling drugs and preventing work under the influence of psychoactive substances using AI.

Environment

During the first quarter of 2024, the environmental department has continued executing the actions of environmental monitoring of the activity and management of the natural environment. Key points of the quarter:

• During the first quarter of the year, three environmental incidents were registered. All of them related to spills over unpaved area. The areas were cleaned, and the waste were handled properly.
• A total rainfall of 481.3 l/m2 was recorded in Q1 2024, which was around 568% more than in the same period of previous year. The total rain collected for the hydrological year (October 2023 to September 2024) is 787.2 l/m2, which is 131% more than the rainfall recorded in the previous hydrological year (same period).
• Upon expiration of the existing permit, in January 2024, Atalaya was granted a new temporary permit valid until January 2026 for an additional 4.1 hm3 per year of fresh water supply for a total of 6.6 hm3 per year.
• The additional measures contemplated in the action plan against dust continued to be implemented, intensifying periodic irrigation, implementing new coordination measures, and carrying out exhaustive monitoring of the emissions generated in the operation.
• All the regular internal controls of diffuse emissions into the atmosphere have been carried out, and the results of the controls are within the limit values. However, in January, PST limit was exceeded at sampling point number 1, and in March, PSD limit was exceeded in five control points (dust intrusion). In the rest, PSD and PST limits were met. The remaining periodic and mandatory controls have been carried out without incidents. In addition, during the quarter, several reports were handed to the Administration bodies.
• Environmental inspections were performed daily, mainly focused on chemical storage and handling, housekeeping, waste management, uncontrolled releases and environmentally friendly practices carried out in the project by ARM's and contractors' personnel. Additionally, dust control and drainage system inspections were performed regularly. 84 inspections in total were carried out during the first quarter, including, plant, mine area and the contractors' camps.
• Environmental inspections were performed daily, mainly focused on chemical storage and handling, housekeeping, waste management, uncontrolled releases and environmentally friendly practices carried out in the project by ARM's and contractors' personnel. Additionally, dust control and drainage system inspections were performed regularly. 82 inspections in total were carried out during the third quarter, including, plant, mine area and the contractors' camps.
• Risk Factors

The Company continues to monitor the principal risks and uncertainties that could materially impact the Company's results and operations, including the areas of increasing uncertainty such as inflationary pressure on goods and services required for the business and geopolitical developments worldwide.

• Critical accounting policies, estimates, judgements, assumptions and accounting changes

As at 31 March 2024, there are no significant changes in critical accounting policies or estimates to those applied in 2023.

Principal activities

Proyecto Riotinto

Proyecto Touro

In November 2019, Atalaya executed the option to acquire 12.5% of Explotaciones Gallegas del Cobre, S.L. the exploration property around Touro, with known additional reserves, which will provide high potential to the Proyecto Touro.

Proyecto Masa Valverde

On 21 October 2020, the Company announced that it entered into a definitive purchase agreement to acquire 100% of the shares of Cambridge Mineria España, S.L. (since renamed Atalaya Masa Valverde, S.L.U.), a Spanish company which fully owns the Masa Valverde polymetallic project located in Huelva (Spain). Under the terms of the agreement Atalaya will make an aggregate €1.4 million cash payment in two instalments of approximately the same amount. The first payment is to be executed once the project is permitted and second and final payment when first production is achieved from the concession.

In November 2023, the exploitation permits for the Masa Valverde and Majadales deposits was officially granted.

Proyecto Ossa Morena

In December 2021, Atalaya announced the acquisition of a 51% interest in Rio Narcea Nickel, S.L., which owns 9 investigation permits.

In Q3 2022, Atalaya increased its ownership interest in POM to 99.9%, up from 51%, following completion of a capital increase that will fund exploration activities. During 2022 Atalaya rejected 8 investigation permits.

Atalaya will pay a total of €2.5 million in cash in three instalments and grant a 1% net smelter return ("NSR") royalty over all acquired permits. The first payment of €0.5 million will be made following execution of the purchase agreement. The second and third instalments of €1 million each will be made once the environmental impact statement ("EIS") and the final mining permits for any project within any of the investigation permits acquired under the Transaction are secured.

Proyecto Riotinto East

Basis of preparation and accounting policies

2.1 Basis of preparation

Overview

These condensed interim financial statements are unaudited.

The unaudited interim condensed consolidated financial statements for the period ended 31 March 2024 have been prepared in accordance with International Accounting Standard 34: Interim Financial Reporting. IFRS comprise the standard issued by the International Accounting Standard Board ("IASB"), and IFRS Interpretations Committee ("IFRICs") as issued by the IASB. Additionally, the unaudited interim condensed consolidated financial statements have also been prepared in accordance with the IFRS as adopted by the European Union (EU), using the historical cost convention and have been prepared on a historical cost basis except for the revaluation of certain financial instruments that are measured at fair value at the end of each reporting period, as explained below.

Going concern

These unaudited condensed interim consolidated financial statements have been prepared based on accounting principles applicable to a going concern which assumes that the Group will realise its assets and discharge its liabilities in the normal course of business. Management has carried out an assessment of the going concern assumption and has concluded that the Group will generate sufficient cash and cash equivalents to continue operating for the next twelve months.

2.2 New standards, interpretations and amendments adopted by the Group

Several amendments and interpretations apply for the first time in 2024, but do not have a material impact on the unaudited condensed interim consolidated financial statements of the Group.

The amendments are effective for annual reporting periods beginning on or after January 1, 2024, with earlier application permitted, and will need to be applied retrospectively in accordance with IAS 8. The objective of the amendments is to clarify the principles in IAS 1 for the classification of liabilities as either current or non-current. The amendments clarify the meaning of a right to defer settlement, the requirement for this right to exist at the end of the reporting period, that management intent does not affect current or non-current classification, that options by the counterparty that could result in settlement by the transfer of the entity's own equity instruments do not affect current or non-current classification. Also, the amendments specify that only covenants with which an entity must comply on or before the reporting date will affect a liability's classification. Additional disclosures are also required for non-current liabilities arising from loan arrangements that are subject to covenants to be complied with within twelve months after the reporting period. The amendments had no material impact on the Group's unaudited condensed interim consolidated financial statements.

IFRS 16 Leases: Lease Liability in a Sale and Leaseback (amendments)

The amendments are effective for annual reporting periods beginning on or after January 1, 2024, with earlier application permitted. The amendments are intended to improve the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction in IFRS 16, while it does not change the accounting for leases unrelated to sale and leaseback transactions. In particular, the seller-lessee determines 'lease payments' or 'revised lease payments' in such a way that the seller-lessee would not recognise any amount of the gain or loss that relates to the right of use it retains. Applying these requirements does not prevent the seller-lessee from recognising, in profit or loss, any gain or loss relating to the partial or full termination of a lease. A seller-lessee applies the amendment retrospectively in accordance with IAS 8 to sale and leaseback transactions entered into after the date of initial application, being the beginning of the annual reporting period in which an entity first applied IFRS 16. The amendments had no material impact on the Group's unaudited condensed interim consolidated financial statements.

The amendments are effective for annual reporting periods beginning on or after January 1, 2024, with earlier application permitted. The amendments supplement requirements already in IFRS and require an entity to disclose the terms and conditions of supplier finance arrangements. Additionally, entities are required to disclose at the beginning and end of reporting period the carrying amounts of supplier finance arrangement financial liabilities and the line items in which those liabilities are presented as well as the carrying amounts of financial liabilities and line items, for which the finance providers have already settled the corresponding trade payables. Entities should also disclose the type and effect of non-cash changes in the carrying amounts of supplier finance arrangement financial liabilities, which prevent the carrying amounts of the financial liabilities from being comparable. Furthermore, the amendments require an entity to disclose at the beginning and end of the reporting period the range of payment due dates for financial liabilities owed to the finance providers and for comparable trade payables that are not part of those arrangements. The amendments have not yet been endorsed by the EU. The amendments had no material impact on the Group's unaudited condensed interim consolidated financial statements.

IAS 21 The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability (Amendments)

The amendments are effective for annual reporting periods beginning on or after January 1, 2025, with earlier application permitted. The amendments specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. A currency is considered to be exchangeable into another currency when an entity is able to obtain the other currency within a time frame that allows for a normal administrative delay and through a market or exchange mechanism in which an exchange transaction would create enforceable rights and obligations. If a currency is not exchangeable into another currency, an entity is required to estimate the spot exchange rate at the measurement date. An entity's objective in estimating the spot exchange rate is to reflect the rate at which an orderly exchange transaction would take place at the measurement date between market participants under prevailing economic conditions. The amendments note that an entity can use an observable exchange rate without adjustment or another estimation technique. The amendments had no material impact on the Group's unaudited condensed interim consolidated financial statements.
