Accordingly, certain information and footnote disclosure normally included in annual financial statements have been omitted or condensed. These condensed interim consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company as at and for the year ended December 3, 204. 7

Capstone Mining Corp. Notes to Condensed Interim Consolidated Financial Statements Three Months Ended March 3, 205 and 204 (tabular amounts expressed in thousands of US dollars, except share amounts) The Company has not applied the following revised or new IFRS that have been issued but were not yet effective at March 3, 205. These accounting standards are not expected to have a significant effect on the Company s accounting policies or financial statements: IFRS 7, Financial Instruments Disclosures (effective January, 208) requires new disclosures resulting from the amendments to IFRS 9. IFRS 9, Financial Instruments (effective January, 208) introduces new requirements for the classification and measurement of financial assets and liabilities. In May 204, the IASB issued IFRS 5 Revenue from Contracts with Customers ("IFRS 5") which supersedes IAS Construction Contracts, IAS 8 Revenue, IFRIC 3 Customer Loyalty Programmes, IFRIC 5 Agreements for the Construction of Real Estate, IFRIC 8 Transfers of Assets from Customers, and SIC 3 Revenue Barter Transactions involving Advertising Services. IFRS 5 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. The standard is effective for annual periods beginning on or after January, 207, with early adoption permitted. The Company is currently evaluating the impact the standard is expected to have on its consolidated financial statements. Certain of the prior year comparative amounts have been reclassified to conform with the presentation adopted for the current period. 3. Financial instruments At March 3, 205 the levels in the fair value hierarchy into which the Company s financial assets and liabilities are measured and recognized on the Condensed Interim Consolidated Balance Sheets at fair value on a recurring basis are categorized as follows: Level Level 2 Level 3 Total Concentrate receivables - 3,02-3,02 Available-for-sale securities (included in other assets in the Condensed Interim Consolidated Balance Sheet) 5,758 - - 5,758 Total financial assets $ 5,758 $ 3,02 $ - $ 8,860 Finance lease obligations $ - $,299 $ - $,299 Share based payment obligations - 2,409 - - Total financial liabilities $ - $ 3,708 $ - $,299 At March 3, 205, there were no financial assets and liabilities measured and recognized at fair value on a non-recurring basis. The Company s policy for determining when a transfer occurs between levels in the fair value hierarchy is to assess the impact at the date of the event or the change in circumstances that could result in a transfer. There were no transfers between Level and Level 2 during the three months ended March 3, 205. 8

Capstone Mining Corp. Notes to Condensed Interim Consolidated Financial Statements Three Months Ended March 3, 205 and 204 (tabular amounts expressed in thousands of US dollars, except share amounts) Valuation methodologies for Level 2 financial assets accounts receivable arising from sales of metals concentrates The Company s metal concentrate sales contracts are subject to provisional pricing with the selling price adjusted at the end of the quotational period. At each reporting date, the Company s accounts receivable on these contracts are marked-to-market based on a quoted forward price for which there exists an active commodity market. There have been no changes in the three months ended March 3, 205 as to how the Company categorizes its financial assets and liabilities by fair-value through profit or loss, available-for-sale, loans and receivables, and other financial liabilities. Fair value of financial assets and liabilities not already measured and recognized at fair value on the Condensed Interim Consolidated Balance Sheets At March 3, 205, the carrying amounts of accounts receivable not arising from sales of metal concentrates, accounts payable and accrued liabilities, and other assets and liabilities are considered to be reasonable approximations of their fair values due to the short-term nature of these instruments. The Company s share-based payment obligations are recorded at fair value based on quoted market prices at the reporting date. The carrying value of the promissory note receivable approximates its fair value due to its demand nature. The fair value of the Company s loan facilities uses current market values and approximates the carrying value. Financial instruments and related risks The Company s activities expose it to financial risks of varying degrees of significance which could affect its ability to achieve its strategic objectives for growth and shareholder returns. The principal financial risks to which the Company is exposed are commodity price risk, credit risk, foreign exchange risk, liquidity risk, and interest rate risk. The Board of Directors has overall responsibility for the establishment and oversight of the Company s risk management framework and reviews the Company s policies on an ongoing basis. There have been no significant changes in the Company s exposure to these financial risks in the three months ended March 3, 205. 4.

Financial and Operational Highlights Financial and Production Highlights for the three months ended March 3, 205 & 204 Net loss of $7.4 million or $0.05 per common share (204 net loss of $4.4 million or $0.0 per common share) which included: o Earnings from mining operations of $4.9 million (204 - $7. million), Realized copper price of $2.47 per pound sold (204 - $2.99 realized price) and a C cash cost of $.89 per payable pound sold (204 $.86 per pound sold). o Production costs included a $2.6 million (204 $0.0 million) non-cash charge related to the write-down of inventory at the Minto Mine, o A non-cash charge of $3.6 million related to the impairment of available-for-sale securities (204 $nil), o Operational restructuring costs of $2.2 million (204 $nil) related to Pinto Valley, o Stand-by fees of $. million (204 $nil) at Minto for reduced open pit mining rates, o $.7 million in current and deferred tax expenses (204 - $7.8 million). Adjusted EBITDA of $24.3 million or $0.06 per common share after making adjustments for certain non-cash and other items (204 $56.4 million or $0.5 per common share). Operating cash flow before changes in working capital of $6.5 million or $0.04 per common share (204 - $50.2 million or $0.4 per common share). These are alternative performance measures: please see Alternative Performance Measures and Reconciliations below. Page 4

Adjusted net loss of $8.9 million or $0.02 per common share after making adjustments for certain non-recurring items (204 net loss of $4.4 million or $0.0 per common share). Working capital increased to $93.6 million at March 3, 205 (which included $22.6 million of cash and cash equivalents) from $06.5 million at December 3, 204. Production of 22,853 tonnes of payable copper at a C cash cost of $.97 per pound of payable copper produced (204 26,245 tonnes at $.92 per pound produced). Revenue of $02.9 million generated primarily from the sale of 20,082 tonnes of payable copper (204 - $60.8 million generated primarily from the sale of 26,60 tonnes of payable copper) at a realized copper price of $2.47 per pound sold (204 $2.99 per pound sold) and a C cash cost of $.89 per pound sold (204 $.86 per pound sold). Additional Highlights Pinto Valley Mine: Produced 5,809 tonnes of copper in concentrates and cathode during Q 205 (204 6,893) at a C cash cost of $.93 per pound of payable copper produced (204 $2.2 per pound produced). During Q 205, an additional hydraulic shovel and three more haul trucks arrived at site as part of the capital considered under the PV2 expansion plan. Completed a reorganization to improve operational efficiency and accountability. As part of the redesign, approximately 40 salaried staff left the organization and a further 30 people changed roles, resulting in a reduction to the salaried workforce of 5% and restructuring costs of $2.2 million recognized in the quarter. Work continued during the quarter to advance two PV3 scenarios towards a Pre-Feasibility study level ( PV3 PFS ). The PV3 PFS base case will include a 0% to 5% increase in throughput and the possibility of a mine life extension beyond 2026 and a second case will evaluate a throughput increase to 90,000 tonnes per day combined with a potential mine life extension. The PV3 PFS is expected to be completed in the third quarter of 205, at which time we will evaluate the two alternatives and the best use of capital. Cozamin Mine: Produced 3,773 tonnes of copper in concentrates during Q 205 (204 5,0 tonnes) at a C cash cost of $.5 per pound of payable copper (204 $.23 per pound produced). Mine development rates were reviewed in Q 205 with a focus on improvement through training, thereby helping to ensure sufficient underground production inventory going forward. Efforts continued throughout Q 205 on the permitting process for additional surface drilling at the Cozamin mine site with the permit expected to be received in Q2 205. Underground access for the Mala Noche vein resource drilling program is advancing on plan with an expected start to the program in Q3 205. Minto Mine: Produced 4,095 tonnes of copper in concentrates during Q 205 (204 5,22 tonnes) at a C cash cost of $2.58 per pound of payable copper produced (204 $.94 per pound produced), which included $0.4 per pound of cost allocated from stockpile (204 $0.04 per pound) which was spent in prior periods, bringing the actual cash expended during Q 205 to $2.44 per pound of payable copper produced (204 $.90 per pound produced). The hearing with the Yukon Water Board on the Water Use Licence Amendment took place in the first week of March and the Company awaits receipt of the licence. The current plan has the mill continuing to process ore from underground and stockpiles, with surface mining on hold until receipt of the required licence, which is expected in Q2 205. These are alternative performance measures: please see Alternative Performance Measures and Reconciliations below. Page 5

Santo Domingo Project: The Company completed the tender process for Engineering, Procurement, and Construction ( EPC ) and Engineering, Procurement, and Construction Management ( EPCM ) packages for project development. Capstone has selected POSCO E&C ( POSCO ) as the preferred EPC fixed price lump sum contractor for the Santo Domingo project. While the EPC contract has not been concluded, Capstone has awarded a Limited Notice to Proceed to the end of Stage-Gate, which will include confirmation of completeness of the engineering and contractual performance guarantee parameters. This award totals approximately $4.5 million and is part of Capstone s previously announced 205 base case budget of $6.9 million (of which Capstone s 70% share is $.8 million). This work is expected to be completed before the end of Q2 205. Following Stage-Gate next steps will be determined and communicated. The total capital cost of the project is expected to be at or below the previously estimated $.7 billion. During Q2 205 the Company expects to present its third addendum for the Environmental Impact Assessment. Based on the current timetable it is now expected to be approved during Q2 205, which aligns with the revised engineering development plan outlined above. A third party objection to the Santo Domingo port concession application was rejected by the Chilean Armed Forces, clearing the way for the anticipated approval of the application in Q2 205. Greenfield Exploration: Exploration work at Project Providencia in Region II, Chile during Q 205 included minor infill soil sampling and trenching. Drilling resumed in late March but was temporarily halted due to extensive flash flooding in the Atacama region. Four separate copper-gold prospects are slated for testing when drilling resumes in Q2 205. Two targets are porphyry-type and two are IOCG / Manto type. To date in 205, a total of 496 metres of RC drilling was completed in two holes before the temporary shutdown. Revised Credit Facility In January 205 Capstone entered into an amended senior secured corporate revolving credit facility ( RCF ) for up to $500-million. This facility amends Capstone's existing senior secured corporate revolving term facility and allowed for the repayment and cancellation of the existing senior secured reducing revolving credit facility. The RCF comprises a committed $440-million plus a $60-million accordion. It has a four-year term maturing in January, 209 (with extension rights on mutual consent), an interest rate of United States LIBOR (London interbank offered rate) plus 3.0% (adjustable in certain circumstances) and a standby fee of 0.675%, payable on the undrawn balance of the facility. The $60-million accordion may be exercised by Capstone once additional credit is committed from existing and/or new lenders. These are alternative performance measures: please see Alternative Performance Measures and Reconciliations below. Page 6
