Atalaya Mining plc ("Atalaya" and/or the "Group")

Condensed Interim Consolidated Financial Statements for the three months ended 31 March 2019

NICOSIA, May 23, 2019 - Atalaya Mining plc (AIM: ATYM; TSX: AYM), the European mining and development company, is pleased to announces its unaudited quarterly results for the three months ended 31 March 2019, together with the unaudited, condensed, interim consolidated financial statements.

Unaudited Financial Highlights

• Revenues of €51.7 million for the three months ended 31 March 2019 ("Q1 2019") compared with €52.7 million for the three months ended 31 March 2018 ("Q1 2018"). The variance was due to stronger average US Dollar rates against the Euro and offset by lower copper prices and slightly lower volumes sold during the period.

• Operating costs during Q1 2019 were €30.0 million compared with €36.4 million in Q1 2018. Lower expenses were mainly due to a reduction in earthworks and changes in inventories.

• Cash costs during Q1 2019 were $1.89/lb of payable copper, an increase from cash costs of $1.77/lb of payable copper in Q4 2018 but lower than Q1 2018 ($2.27/lb). The decrease against Q1 2018 was mainly the result of lower mining, and technical services, maintenance, penalties and concentrate deductions. All-in Sustaining Costs ("AISC") during Q1 2019 amounted to $2.18/lb of payable copper, an increase from $2.00/lb of payable copper during Q4 2018 but lower than Q1 2018 ($2.65/lb).

• Management expects cash costs for the year to remain within the guidance range provided of $1.95/lb to $2.15/lb and AISC from $2.25/lb to $2.45/lb.

• EBITDA of €19.5 million in Q1 2019 compared with €15.0 million in Q1 2018. The increase in EBITDA was mainly the result of lower operating costs in Q1 2019.

• Q1 2019 profit after tax amounted to €14.2 million (or 10.3 cents basic earnings per share) compared with a profit for Q1 2018 of €8.8 million (or 6.5 cents basic earnings per share).

• Inventories of concentrate at 31 March 2019 amounted to €2.4 million (€3.0 million at 31 December 2018).

• At the end of Q1 2019 working capital was €9.0 million, a €0.6 million increase from €8.4 million at the end of Q4 2018. Unrestricted cash balances as at 31 March 2019 amounted to €23.8 million.

Financial Highlights (continued)

• Cash flow from operating activities before changes in working capital was €20.3 million for Q1 2019 compared with a cash flow of €15.2 million during Q1 2018.

• Net cash flow from operating activities after changes in working capital was €8.1 million for Q1 2019 compared with a cash flow of €18.4 million during Q1 2018.

Operational Highlights

Proyecto Riotinto

• Copper production during Q1 2019 was 10,219 tonnes, an increase of 8.2% compared with 9,441 tonnes produced during Q1 2018.

• Ore processed during Q1 2019 was 2,445,977 tonnes, an increase on Q1 2018 when ore processed amounted to 2,206,861 tonnes.

• Copper recovery during the quarter was 90.27%, higher than 88.47% achieved in Q1 2018.

• The Company maintains its previously stated copper production guidance for 2019 of 45,000 - 46,500 tonnes.

Expansion to 15Mtpa at ProyectoRiotinto

• The 15Mtpa expansion project has progressed materially during the quarter with expected mechanical completion on track for the end of Q2 2019. Overall progress completion at the end of the quarter was 97% with construction reporting 72% completion.

• The new primary crushing area is mechanically well advanced with electrical works progressing. In the new milling area, mechanical activities are progressing according to plan. New flotation and concentrate handling areas are in the final stages of commissioning.

Proyecto Touro

• During the quarter, feedback has been received from the relevant Administration bodies as part of the assessment of the environmental impact studies. The Company is addressing additional requests to complement current management plans. This stage of the process is expected to last until the end of Q2 2019.

Legal updates

• On 29 March 2019, the Company announced that it had received notification from the Supreme Court in Spain that it does not have jurisdiction over the appeal made by the Junta de Andalucía ("JdA") and the Company, which voluntarily joined the appeal as co-defendant. Therefore, the previously announced Ruling made by the Tribunal Superior de Justicia de Andalucía ("TSJA") remains valid. The Company will continue operating the mine normally and has been advised the Ruling will not impact its operations at Proyecto Riotinto.

• On 26 April 2019, the Company announced a judgment related to the Mining Permits to operate Proyecto Riotinto (the "Mining Permits") was handed down by the TSJA. The TSJA declared the Mining Permits are linked to the Environmental Permits, ruled by the same tribunal on September 2018. The new ruling on the Mining Permits is based on the requirement to have an AAU before issuing mining permits and therefore invalidates the existing Mining Permits. The TSJA has not accepted the requests by EeA for the cessation of activities at the mine and an increase in the scope of the environmental plan.

• All the pending claims made by EeA have now been ruled by the TSJA. Atalaya continues to work with its legal advisors to evaluate the possibility of appealing the ruling and to ensure the JdA addresses all procedural points raised in both rulings. The Company continues operating the mine normally as the rulings do not state the operation at Proyecto Riotinto is to be ceased, not even temporarily and it is still confident that the ruling will not impact its operations at Proyecto Riotinto. The JdA has publicly supported the continuation of the mine.

Alberto Lavandeira, CEO commented:

"We are delighted withAtalaya's financial performance for Q1 2019, in which reduced operating costshave led to a substantial increase in profits of over 60%. Progress with ourexpansion to 15Mtpa at Proyecto Riotinto is proceeding to plan with mechanicalcompletion on track for the end of Q2 2019. Once completed, we will enjoyimproved operational efficiencies and reduced cash costs compared with 2018. Wemaintain our guidance for full year 2019 production of 45,000 to 46,500 tonnesof copper."

Three months operational review

Copper production at Proyecto Riotinto for Q1 2019 increased to 10,219 tonnes from 9,441 tonnes reported in Q1 2018, and 11,172 tonnes in Q4 2018, representing an increase and a decrease of 8.2% and (8.5)%, respectively. Ore milled was consistent with previous quarters and in line with management's expectations. Copper head grade was in line with previous quarter and with expectations. The increase in copper production during the quarter compared with Q1 2018 was mainly attributable to a record average recovery of 90.26%.

Mining operations are progressing according to plan and at similar levels to previous quarters. On a combined basis, ore, waste and marginal ore amounted to 2.3 million m³ in Q1 2019 versus 2.5 million m³ in Q4 2018. Additional mining equipment is available on site in anticipation of the increase in production scheduled for H2 2019.

During Q1 2019, the Group sold 45,172 tonnes of concentrates, compared with 44,487 tonnes in Q4 2018 and 48,682 tonnes in Q1 2018. On-site concentrate inventories at the end of the quarter were approximately 2,936 tonnes. All concentrate in stock at the beginning of the quarter and produced during the quarter was delivered to the port at Huelva.

Exploration around Proyecto Riotinto is progressing well with two drilling programmes under way. Remaining massive sulphides and stockwork mineralisation are being targeted under the Atalaya pit. Lateral extensions of massive sulphides and stockwork are also being drilled around Filon Sur. Geological modelling is being updated as information becomes available.

4. Overview of thefinancial results

The following table presents summarised consolidated income statements for the three months ended 31 March 2019, with comparatives for the three months ended 31 March 2018.

Three months financial review

Revenues for the three month period ended 31 March 2019 amounted to €51.7 million (Q1 2018: €52.7 million). Lower revenues, compared with the same quarter in the previous year, were mainly driven by stronger US Dollar average rates against Euro and offset by lower copper prices and slightly lower volumes during the period.

Realised prices of $2.80/lb copper during Q1 2019 compared with $3.03/lb copper in Q1 2018. All concentrates were sold under offtake agreements in place.

Operating costs for the three month period ended 31 March 2019 amounted to €30.1 million, compared with €36.4 million in Q1 2018. The decrease was mainly due to lower mining and processing variable costs, in addition to a lesser depreciation charge (due to an extension of the life of mine as per updated reserves and resources report in mid-2018).

Cash costs of $1.89/lb payable copper during Q1 2019 compared with $2.27lb payable copper in the same period last year. Cash costs were impacted by lower mining, technical services and maintenance costs and higher capitalised stripping costs compared with Q1 2018. Capitalised stripping costs during Q1 2019 amounted to €0.8 million compared with €0.3 million in Q1 2018. All-in sustaining costs in the reporting quarter were $2.18/lb payable copper compared with $2.65/lb payable copper in Q1 2018. The decrease in AISC compared with Q1 2018 mainly related to lower sustaining capex and agency fees as well as lower cash operating costs.

Sustaining capex for Q1 2019 amounted to €1.7 million compared with €2.7 million in Q1 2018. Sustaining capex related to enhancements in processing systems of the plant and continuous development programmes at the tailings storage facilities.

Administrative and other expenses amounted to €1.9 million (Q1 2018: €1.1 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 at Proyecto Riotinto for the three month period ended 31 March 2019 amounted to €0.2 million, similar amount that in Q1 2018. All exploration costs at Proyecto Touro are capitalised.

EBITDA for the three months ended 31 March 2019 amounted to €19.5 million compared with Q1 2018 of €15.0 million.

The main item below the EBITDA line is depreciation and amortisation of €3.4 million (Q1 2018: €4.1 million). Net financing costs for Q1 2019 amounted to €31k compared with €7k in Q1 2018.

Copperprices

The average realised copper price decreased 7.6% from US$3.03 per pound in Q1 2018 to US$2.80 per pound in Q1 2019.

The average prices of copper for the three months ended 31 March 2019 and 2018 are summarised below:

Realised copper prices for the reporting period noted above have been calculated using payable copper and including provisional invoices and final settlements of quotation periods ("QPs") together. Lower realised prices than market averages are mainly due to the final settlement of invoices where QP was fixed in the previous quarter due to a short open period when copper prices were lower. The realised price of shipments during the quarter excluding QP was approximately $2.82/lb.

5. Non-GAAP Measures

Atalaya has included certain non-IFRS measures including "EBITDA", "Cash Cost per pound of payable copper", "All In Sustaining Costs" ("AISC") and "realised prices" in this report. Non-IFRS measures do not have any standardised meaning prescribed under IFRS, and therefore they may not be comparable to similar measures presented by other companies. These measures are intended to provide additional information and should not be considered in isolation or as a substitute for indicators prepared in accordance with IFRS.

EBITDA includes gross sales net of penalties and discounts and all operating costs, excluding finance, tax, impairment, depreciation and amortisation expenses.

Cash Cost per pound of payable copper includes cash operating costs, including treatment and refining charges ("TC/RC"), freight and distribution costs net of by-product credits. Cash Cost per pound of payable copper is consistent with the widely accepted industry standard established by Wood Mackenzie and is also known as the C1 cash cost.

AISC per pound of payable copper includes C1 Cash Costs plus royalties and agency fees, expenditures on rehabilitation, capitalised stripping costs, exploration and geology costs, corporate costs and sustaining capital expenditures.

Realised price per pound of payable copper is the value of the copper payable included in the concentrate produced before deducting the penalties, discounts, credits and other features governed by the offtake agreements of the Group and all discounts or premiums provided in commodity hedge agreements with financial institutions, expressed in USD per pound of payable copper. Realised price is consistent with the widely accepted industry standard definition.

6. Liquidity and capitalresources

Atalaya monitors factors that could impact its liquidity as part of Atalaya's overall capital management strategy. Factors that are monitored include, but are not limited to, the market price of copper, foreign currency rates, production levels, operating costs, capital and administrative costs.

The following is a summary of Atalaya's cash position and cash flows as at 31 March 2019 and 31 December 2018.

Liquidity information

Unrestricted cash and cash equivalents as at 31 March 2019 decreased to €23.8 million from €32.8 million at 31 December 2018. The decrease in cash balances is the result of net cash flow incurred in the period. Cash balances are unrestricted and include balances at operational and corporate level.

Restricted cash remains at €0.3 million as at 31 March 2019 and mainly relates to deposit bond guarantees.

6. Liquidityand capital resources (continued)

As of 31 March 2019, Atalaya reported a working capital surplus of €9.0 million, compared with a working capital surplus of €8.4 million at 31 December 2018. The main liability of the working capital is trade payables related to Proyecto Riotinto contractors. At 31 March 2019, trade payables have been reduced by circa 17% compared with the same period last year.

Overview of the Group'scash flows

Three months cash flows review

Cash and cash equivalents decreased by €9.0 million during the three months ended 31 March 2019. This was due to the net results of cash from operating activities amounting to €8.1 million and the cash used in investing activities amounting to €17.1 million.

Cash generated from operating activities before working capital changes was €20.3 million. Atalaya increased its trade receivables in the period by €11.9 million, decreased its inventory levels by €0.8 million and decreased its trade payables by €1.0 million.

Investing activities during the quarter consumed €17.1 million, relating mainly to the expansion project Capex and sustaining capex mostly in enhancements in processing systems of the plant.

Foreignexchange

Foreign exchange rate movements can have a significant effect on Atalaya's operations, financial position and results. Atalaya's sales are denominated in U.S. dollars ("USD"), while Atalaya's operating expenses, income taxes and other expenses are mainly denominated in Euros ("EUR"), and to a much lesser extent in British Pounds ("GBP").

Accordingly, fluctuations in the exchange rates can potentially impact the results of operations and carrying value of assets and liabilities on the balance sheet.

During the three months ended 31 March 2019, Atalaya recognised a foreign exchange profit of €0.7 million. Foreign exchange losses mainly related to change in the period end EUR and USD conversion rates, as all sales are cashed and occasionally held in USD.

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

7. Deferredconsideration

In September 2008, the Group moved to 100% ownership of Atalaya Riotinto Mineral S.L. ("ARM") (and thus full ownership of Proyecto Riotinto) by acquiring the remaining 49% of the issued capital of ARM. At the time of the acquisition, the Group signed a Master Agreement (the "Master Agreement") with Astor Management AG ("Astor") which included a deferred consideration of €43.9 million (the "Deferred Consideration") payable as consideration in respect of the acquisition. The Company also entered into a credit assignment agreement at the same time with a related company of Astor, Shorthorn AG, pursuant to which the benefit of outstanding loans was assigned to the Company in consideration for the payment of €9.1 million to Shorthorn (the "Loan Assignment").

The Master Agreement has been the subject of litigation in the High Court and the Court of Appeal that has now concluded. As a consequence, ARM must apply any excess cash (after payment of operating expenses, sustaining capital expenditure, any senior debt service requirements and up to US$10 million per annum (for non-Proyecto Riotinto related expenses)) to pay the consideration due to Astor (including the Deferred Consideration and the amount of €9.1 million payable under the Loan Assignment). "Excess cash" is not defined in the Master Agreement leaving ambiguity as to how it is to be calculated.

As at 31 March 2019, no consideration has been paid.

The amount of the liability recognised by the Group is €53 million. The effect of discounting remains insignificant, in line with 2018 assessment, and therefore the Group has measured the liability for the Astor deferred consideration on an undiscounted basis.

8. Corporatesocial responsibility

During the quarter, Atalaya has continued its involvement in social responsibility through several activities through Fundación Atalaya Riotinto.

Continuing its work in education and entrepreneurship, the Company has renewed the Language School Program in cooperation with the City Council of Nerva, and has restarted the school visits program of the mining region to Atalaya´s facilities.

The Company has launched the second edition of "el Reto Malacate": an initiative to reward the best business project to be settled in the region.

In cooperation with the City Hall of Minas de Riotinto, Atalaya has provided the necessary funding for the opening of the Museum of the Town, which contains large scale models that represent the old town of Minas de Riotinto.

Atalaya has also reached agreements with the towns of Nerva and Campofrío to, respectively, repopulate an important avenue with palm trees, and labelling through town´s advertising to attract tourism.

Also, in collaboration with Asociación Matilde, the Company has cooperated in a program consisting of restoring an organic local garden and selling its products to the market. People involved in this project comes from families at risk of social exclusion.

Atalaya has also taken part into the GAVI program (Business Alliance for Childhood Vaccination) in collaboration with the Fundación La Caixa" and Bill & Melinda Gates Foundation.

9. Healthand safety

The prevention of occupational hazards has the highest priority in the Company. The investigation and the analysis of any type of accident is fully performed under the "methodology of the 5 whys" to both own personnel and contractors, even if the accident results in no lost time injury.

During Q1 2019 the Company worked alongside with contractors to strongly reinforce the compliance of safety regulations and accident prevention, establishing a quality assessment of the safety actions carried out by Atalaya.

In addition, the Company is running a program for the evaluation of psychosocial factors in the work environment. For this purpose, Atalaya and the employees 'representatives has formed a working group, supported by an external consulting company. The Company has given out a survey to all its personnel to be submitted on a voluntary basis and entirely confidential. The final results of the survey will be analysed by the external consultant and the Company will receive feedback in the coming months, so to implement a guideline in the improvement of working conditions.

9. Healthand safety (continued)

The Company is also developing a training program for high-risk activities. This program involves trainings in the assembling of lifelines, interlocking of equipment, working in cramped spaces, etc.

All these lines of work are resulting in enhancements of safety with respect to the previous year, meaning just two accidents with a minor loss in the first quarter of 2019.

The Company carries on working towards zero damages.

10. Environmentalmanagement

During the first quarter of 2019, the environmental department has continued executing the actions of environmental monitoring of the activity, management of the natural environment and the usual historical heritage. Key points of the quarter:

- An analysis of the evolution of the diffuse contamination has been performed, registering a 37% decrease in the pollutant load towards the Tinto and Odiel rivers, thanks to the restoration and water management actions carried out since the beginning of the mining operation.

- Results in terms of emissions to the atmosphere and air quality from 2018 have been analysed and veryfied that the limit values and established target values were met in all the controls carried out.

- Results from 2018 analysis showed a reduction of 16% in the production of hazardous waste and 25% in non-hazardous waste with respect to 2017.

Archaeological excavation work has continued, focusing on the Look Out site for its release as soon as possible.

11. Risk factors

They have been prepared using accounting bases and policies consistent with those used in the preparation of the consolidated financial statements of the Company and the Group for the year ended 31 December 2018. These condensed interim consolidated financial statements do not include all of the disclosures required for annual financial statements, and accordingly, should be read in conjunction with the consolidated financial statements and other information set out in the Company's 31 December 2018 Annual Report. The accounting policies are unchanged from those disclosed in the annual consolidated financial statements.

The Directors have formed a judgment at the time of approving the financial statements that there is a reasonable expectation that the Company and the Group have adequate available resources to continue in operational existence for the foreseeable future.

2. Basisof preparation and accounting policies (cont.)

2.1Basis of preparation (cont.)

(b) Going concern

These consolidated financial statements have been prepared on the basis of 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.

2.2Adoption of new and revised International Financial Reporting Standards (IFRSs)

The Group has adopted all the new and revised IFRSs and International Accounting Standards (IASs) which are relevant to its operations and are effective for accounting periods commencing on 1 January 2019. The adoption of these Standards did not have a material effect on the condensed interim consolidated financial statements.

IFRS 16 - Leases

The new standard on leases that replaces IAS 17, IFRIC 4, SIC-15 and SIC-27. Under the provisions of the standard most leases, including the majority of those previously classified as operating leases, will be brought onto the statement of financial position, as both a right-of-use asset and a largely offsetting lease liability. The right-of-use asset and lease liability are both based on the present value of lease payments due over the term of the lease, with the asset being depreciated in accordance with IAS 16 'Property, Plant and Equipment' and the liability increased for the accretion of interest and reduced by lease payments.

As of the date of the Report, Atalaya has completed the assessment of the potential impact of IFRS 16 on its consolidated financial statements concluding that there is no material impact. The actual impact of applying IFRS 16 on the consolidated financial statements in the period of initial application will depend on future economic conditions, including the Group´s borrowing rate at 1 January 2019, the composition of Atalaya´s borrowing rate at 1 January 2019, the composition of Atalaya´s portfolio at that date, its latest assessment of whether it will exercise any lease renewal options, and the extent to which Atalaya chooses to use practical expedients and recognition exemptions. The directors continue to consider the potential effects on the Group's financial statements and do not currently expect that there will be a material impact, given the current market and internal conditions.

2.3Fair value estimation

The fair values of the Group's financial assets and liabilities approximate their carrying amounts at the reporting date.

The fair value of financial instruments traded in active markets, such as publicly traded trading and other financial assets is based on quoted market prices at the reporting date. The quoted market price used for financial assets held by the Group is the current bid price. The appropriate quoted market price for financial liabilities is the current ask price.

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Group uses a variety of methods, such as estimated discounted cash flows, and makes assumptions that are based on market conditions existing at the reporting date.

Fairvalue measurements recognised in the consolidated statement of financialposition

The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, Grouped into Levels 1 to 3 based on the degree to which the fair value is observable.

• Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

• Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

2.3Fair value estimation (cont.)

2.4Critical accounting estimates and judgements

The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities at the date of the consolidated financial statements. Estimates and assumptions are continually evaluated and are based on management's experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.

Provisions are recognised when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the amount can be made. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost.

A full analysis of critical accounting estimates and judgements is set out in Note 3.4 to the 2018 audited financial statements.

3.Business and geographical segments

Businesssegments

The Group has only one distinct business segment, being that of mining operations, which include mineral exploration and development.

Copper concentrates produced by the Group are sold to three off-takers as per the relevant offtake agreement (Note 18.3)

Geographicalsegments

The Group's mining activities are located in Spain. The commercialisation of the copper concentrates produced in Spain is carried out through Cyprus. Sales transactions to related parties are on arm's length basis in a similar manner to transaction with third parties. Accounting policies used by the Group in different locations are the same as those contained in Note 2.

(*) For the purposes of the geographical segment, in 2019 revenues have been reallocated between Cyprus and Span as per IFRS 15. Comparatives for 2018 have not been restated,

4. Revenue

All revenue from copper concentrate is recognised at a point in time when the control is transferred. Revenue from freight services is recognised over time as the services are provided.

⁽¹⁾ Provisional pricing impact represented the change in fair value of the embedded derivative arising on sales of concentrate.

5. Net finance cost

⁽¹⁾ Interest income relates to interest received on bank balances

6. Earnings per share

The calculation of the basic and fully diluted loss per share attributable to the ordinary equity holders of the Company is based on the following data:

At 31 March 2019 there are nil warrants (Note 11) and 913,000 options (Note 12) (2018: 262,569 warrants and 1,334,333 options) which have been included when calculating the weighted average number of shares for 2018.

7. Property, plant andequipment

⁽¹⁾ Mine rehabilitation assets and Rumbo Royalty Buyout.

⁽²⁾ Includes motor vehicles, furniture, fixtures and office equipment which are depreciated over 5-10 years.

⁽³⁾ Stripping costs

⁽⁴⁾ Assets under construction at 31 March 2019 were €77.3 million (2018: €62.0 million) which include the capitalisation of costs related to the Expansion Project and sustaining capital expenditures.

The above fixed assets are located mainly in Spain.

8. Intangible assets

(1) Permits and R&D include an amount of €5.0 million and an amount of €1.9 million respectively that relate to the Touro Project mining rights.

In July 2018, the Company announced an updated technical report on the Mineral Resources Ltd. and reserves of The Riotinto Project. The Report increases the open pit mineral reserves by 29% and stated the life of mine as 13.8 years, considering the on-going expansion of the processing plant.

The ultimate recovery of balances carried forward in relation to areas of interest or all such assets including intangibles is dependent on successful development, and commercial exploitation, or alternatively the sale of the respective areas.

The Group conducts impairment testing on an annual basis unless indicators of impairment are not present at the reporting date. In considering the carrying value of the assets at The Riotinto Project, including the intangible assets and any impairment thereof, the Group assessed that no indicators were present as at 31 March 2019 and thus no impairment has been recognised.

9. Inventories

As of 31 March 2019, copper concentrate produced and not sold amounted to 2,936 tonnes (31 Dec 2018: 4,667 tonnes). Accordingly, the inventory for copper concentrate was €2.4 million (31 Dec 2018: €3.0 million). During the period the Group recorded cost of sales amounting to €33.5 million (Q1 2018: €40.5 million).

Materials and supplies relate mainly to machinery spare parts. Work in progress represents ore stockpiles, which is ore that has been extracted and is available for further processing.

10. Trade and otherreceivables

Trade receivables are shown net of any interest applied to prepayments. Payment terms are aligned with offtake agreements and market standards and generally are 7 days on 90% of the invoice and the remaining 10% at the settlement date which can vary between 1 to 5 months. The fair values of trade and other receivables approximate to their book values.

11. Share capital and share premium

Authorisedcapital

The Company's authorised share capital is 200,000,000 ordinary shares of Stg £0.075 each.

Issuedcapital

2019

There were no changes in share capital during the three months ended 31 March 2019.

11. Share capital and sharepremium (continued)

2018

a) On 13 February 2018, the Company issued 192,540 new ordinary shares of £0.075 to Rumbo at a price of £1.867, thus creating a share premium of €410,146.

b) On 13 February 2018, the Company was notified that certain employees exercised options over 29,000 ordinary shares of £0.075 at a price of £1.44, thus creating a share premium of €44,576.

c) On 5 April 2018, the Company entered into an agreement with Rumbo to purchase the whole royalty agreement for a total consideration of US$4,750,000 to be paid through the issuance of 1,600,907 new ordinary shares of £0.075 at a price of £2.118 per share. After this transaction the share premium increased by €3,887,128. On 13 April 2018, the new ordinary shares were issued to Rumbo.

d) On 1 June 2018, 262,569 warrants were exercised at £1.425 per ordinary share. Hence, 262,569 new ordinary shares of £0.075 were issued, thus creating a share premium of €405,087.

Warrants

All warrants had been exercised in June 2018 (see d) above).

As at 31 March 2019, there were no warrants.

12. Other reserves

12. Other reserves (continued)

⁽¹⁾ Depletion factor reserve

At 31 December 2018, the Group has disposed €5,050k as a depletion factor reserve in order to fulfil with the Spanish Corporate Tax Act.

⁽²⁾ Available-for-sale investments reserve

As at 31 December 2017 this reserve recorded fair value changes on available-for-sale investments. On disposal or impairment, the cumulative changes in fair value were recycled to the income statement. These assets were reclassified upon adoption of IFRS 9.

⁽³⁾ Fair value reserve of financial assets at FVOCI

The Group has elected to recognise changes in the fair value of certain investments in equity securities in OCI, as explained in (2) above. These changes are accumulated within the FVOCI reserve within equity. The Group transfers amounts from this reserve to retained earnings when the relevant equity securities are derecognised.

⁽⁴⁾ Non-distributable reserve

To comply with Spanish Law on Corporations, the Group needed to record a reserve when profit generated equal to a 10% of profit/(loss) for the year until 20% of share capital is reached.

⁽⁵⁾ Distributable reserve

As result of the profit generated in 2018, the Group decided to record a distributable reserve.

In general, option agreements contain provisions adjusting the exercise price in certain circumstances including the allotment of fully paid ordinary shares by way of a capitalisation of the Company's reserves, a sub division or consolidation of the ordinary shares, a reduction of share capital and offers or invitations (whether by way of rights issue or otherwise) to the holders of ordinary shares.

Details of share options outstanding as at 31 March 2019:

13. Trade and otherpayables

Trade payables are mainly for the acquisition of materials, supplies and other services. These payables do not accrue interest and no guarantees have been granted. The fair value of trade and other payables approximate their book values.

Trade payables are non-interest-bearing and are normally settled on 60-day terms.

14. Provisions

Rehabilitation provision

Rehabilitation provision represents the accrued cost required to provide adequate restoration and rehabilitation upon the completion of production activities. These amounts will be settled when rehabilitation is undertaken, generally over the project's life.

The discount rate used in the calculation of the net present value of the provision as at 31 March 2019 was 1.87%, which is the 15-year Spain Government Bond rate (31 December 2018: 1.87%, which is the 15-year Spain Government Bond rate). An inflation rate of 1.5% is applied on annual basis.

Legalprovision

The Group has been named a defendant in several legal actions in Spain, the outcome of which is not determinable as at 31 March 2019. Management has reviewed individually each case and made a provision of €129 thousand for these claims, which has been reflected in these unaudited interim consolidated financial statements.

15. Deferred consideration

In September 2008, the Group moved to 100% ownership of Atalaya Riotinto Mineral S.L. ("ARM") (and thus full ownership of Proyecto Riotinto) by acquiring the remaining 49% of the issued capital of ARM. At the time of the acquisition, the Group signed a Master Agreement (the "Master Agreement") with Astor Management AG ("Astor") which included a deferred consideration of €43.9 million (the "Deferred Consideration") payable as consideration in respect of the acquisition. The Company also entered into a credit assignment agreement at the same time with a related company of Astor, Shorthorn AG, pursuant to which the benefit of outstanding loans was assigned to the Company in consideration for the payment of €9.1 million to Shorthorn (the "Loan Assignment").

The Master Agreement has been the subject of litigation in the High Court and the Court of Appeal that has now concluded. As a consequence, ARM must apply any excess cash (after payment of operating expenses, sustaining capital expenditure, any senior debt service requirements and up to US$10 million per annum (for non-Proyecto Riotinto related expenses)) to pay the consideration due to Astor (including the Deferred Consideration and the amount of €9.1 million payable under the Loan Assignment). "Excess cash" is not defined in the Master Agreement leaving ambiguity as to how it is to be calculated.

As at 31 March 2019, no consideration has been paid.

15. Deferred consideration (continued)

The amount of the liability recognised by the Group is €53 million. The effect of discounting remains insignificant, in line with prior year's assessment, and therefore the Group has measured the liability for the Deferred Consideration on an undiscounted basis.

16. Acquisition, incorporation and disposal of subsidiaries

There were neither acquisition, nor incorporation, nor disposal of subsidiaries during the three month period to 31 March 2019.

On 22 May 2019 the Group sold its remaining 10% in Eastern Mediterranean Minerals (Cyprus) Limited ("EMM"). Refer to events after reported date set out in Note 22.

17. Wind-up of subsidiaries

There were no operations wound-up during the three month period to 31 March 2019.

18. Related party transactions

The following transactions were carried out with related parties:

18.1Compensation of key management personnel

The total remuneration and fees of Directors (including Executive Directors) and other key management personnel was as follows:

18.2 Share-basedbenefits

The directors and key management personnel have not been granted any options during the three month period ended 31 March 2019 (Q1 2018: nil).

18.3 Transactions with relatedparties/shareholders

i) Transaction with shareholders

18. Related party transactions (continued)

ii) Period-end balances with related parties

The above balances bear no interest and are repayable on demand.

iii) Period-end balances with shareholders

The above debtor balance arising from sales of goods and other balances bear no interest and is repayable on demand.

19. Contingent liabilities

Judicialand administrative cases

In the normal course of business, the Group may be involved in legal proceedings, claims and assessments. Such matters are subject to many uncertainties, and outcomes are not predictable with assurance. Legal fees for such matters are expensed as incurred and the Group accrues for adverse outcomes as they become probable and estimable.

The Junta de Andalucía notified the Group of another disciplinary proceeding for unauthorised discharge in 2014. The Group submitted the relevant defence arguments on 10 March 2015 but has had no response or feedback from the Junta de Andalucía since the submissions. Based on the time that has lapsed without a response, it is expected that the outcome of this proceedings will also be favourable for the Group. Once the necessary time has lapsed, the Group will ask for the Administrative File to be dismissed.

Receiptof rulings of claims made by an environmental Group

On 26 September 2018, Atalaya received notice from the Tribunal Superior de Justicia de Andalucía ("TSJA") ruling in favour of certain claims made by environmental group Ecologistas en Accion ("EeA") against the government of Andalucía ("Junta de Andalucía" or "JdA") and Atalaya, as co-defendant in the case.

In July 2014, EeA had filed a legal claim to JdA with a request to declare null the Unified Environmental declaration (in Spanish, Authorization Ambiental Unificada, or "AAU") granted to Atalaya Riotinto Minera, S.L.U. dated 27 March 2014, which was required in order to secure the required mining permits for Proyecto Riotinto. The judgment, in spite of annulling the AAU on procedural grounds, made very clear that the AAU was correct and therefore, rejected the issues raised by EeA and confirmed the decision of JdA not to suspend the AAU.

The JdA filed for appeal to the Supreme Court. Although the claim was against the JdA, Atalaya, being an interested party in the process, voluntarily joined as co-defendant to ask for permission to appeal to the Supreme Court in Spain.

On 29 March 2019, Atalaya announced the receipt of notification from the Supreme Court in Spain stating that it does not have jurisdiction over the appeal made by the Junta de Andalucía and the Company, which voluntary joined the appeal as con-defendant.

The main legal consequence of the Supreme Court rejection is the ruling of the TSJA dated 26 September 2018 is now final and enforceable and the environmental authority must repair the defect in the process. The Company is currently in discussions to the Junta de Andalucía to resolve the formal defects identified by the Tribunal Superior de Justicia de Andalucía.

19. Contingent liabilities (cont.)

In addition to the legal procedure described above, on 26 April 2019, the Company announced a judgment related to the Mining Permits to operate Proyecto Riotinto (the "Mining Permits") was handed down by the TSJA. The TSJA declared the Mining Permits are linked to the Environmental Permits, ruled by the same tribunal on September 2018. The new ruling on the Mining Permits is based on the requirement to have an AAU before issuing mining permits and therefore invalidates the existing Mining Permits. The TSJA has not accepted the requests by EeA for the cessation of activities at the mine and an increase in the scope of the environmental plan.

All the pending claims made by EeA have now been ruled by the TSJA. Atalaya continues to work with its legal advisors to evaluate the possibility of appealing the ruling and to ensure the Junta de Andalucía addresses all procedural points raised in both rulings. The Company continues operating the mine normally as the rulings do not state the operation at Proyecto Riotinto is to be ceased, not even temporarily and it is still confident that the ruling will not impact its operations at Proyecto Riotinto. The JdA has publicly stated support for the continued and normal operations at the Riotinto mine.

20. Commitments

There have been no new commitments during the quarter.

21. Significant events

There have been no significant events during the quarter other than as disclosed in the financial statements and the notes above.

22. Events after the reporting period

Judgmenton the Mining Permits

On 26 April 2019, the Company announcement the ruling on the Mining Permits granted the by the Junta de Andalucía. Note 19.

Disposalof subsidiary

On 20 March 2019, the Board of Directors approved the disposal of the 10% free-carried investment of Atalaya in Eastern Mediterranean Minerals (Cyprus) Limited ("EMM"), an exploration company with interest in Cyprus. On 22 May 2019 the Group sold its remaining 10% for an immaterial consideration in Eastern Mediterranean Minerals (Cyprus) Limited ("EMM").
