(all amounts in US dollars, unless otherwise noted)

Vancouver, British Columbia – Ero Copper Corp. (TSX: ERO) ("Ero" or the "Company") today is pleased to announce its financial results for the three months ended March 31, 2018. Management will host a conference call tomorrow, Tuesday, May 8, 2018, at 11:30 a.m. Eastern to discuss the results. Dial in details for the call can be found near the end of this news release.


  • First quarter copper production of 4,845 tonnes of copper;
  • First quarter C1 Cash Costs* of $1.63 per pound of copper produced;
  • Generated $7.1 million in EBITDA* (Adjusted EBITDA* of $6.2 million) during the three month period ended March 31, 2018;
  • Net loss attributable to owners of the Company of $4.1 million ($0.05 per share on a diluted basis) during the three month period ended March 31, 2018;
  • Ended the first quarter with cash position of $29.3 million; and,
  • Reiterated full year production, capital and operating cost guidance for 2018.

"Our operational results from the first quarter of 2018 were in line with our expectations. At the Pilar underground mine we were pleased to see quarter-on-quarter increases in production volumes and grade. Additionally, we made significant headway during the quarter on our programs to continue optimizing and improving production including the near-completion of a maintenance facility, fuel station and shotcrete batch plant in the lower levels of the mine. These improvements should translate into benefits in subsequent quarters from an underground mining cost and productivity perspective.
Open pit production was lower quarter-on-quarter as waste stripping at the Surubim Mine, previously envisioned to occur during the fourth quarter of 2017, was deferred into the first quarter of 2018 due to the longer than anticipated mine life at the Suҫuarana Mine.

At Vermelhos, our newest mine, underground development has continued to outpace forecast development rates with 961 meters of total development completed during the quarter. Underground infrastructure has now been completed to the first four production levels of the main Vermelhos ore body and those levels are now being prepared for gallery development. While we are maintaining our outlook for start-up of Vermelhos in the fourth quarter of 2018, we are focused on several opportunities to further advance this timeline.

On exploration, we remain very excited about several near-term opportunities we are evaluating at the Pilar Mine, the Surubim Mine in the central portion of the Valley as well as at the Vermelhos Mine. As we are nearing the conclusion of resource upgrade programs that were prioritized early this year, our exploration programs are beginning to focus on new target areas in and around each of the mining operations. Subsequent to the end of the quarter, we also commenced our district-wide airborne geophysical survey designed to target high-grade mineralization throughout the Curaçá Valley. Data processing commenced contemporaneously with the start of the program and we hope to begin prioritizing new regional targets in the coming months." commented David Strang, President & CEO of Ero Copper.

*EBITDA, Adjusted EBITDA, and C1 Cash Cost of copper produced (per lb) are non-IFRS measures – see the Notes section of this press release for a discussion on non-IFRS Measures


  • Mining & Milling Operationsin line with expectations
    • Quarter-on-quarter increases in underground tonnes and grade mined totalling 229.8 thousand tonnes ("kt") grading 2.14% copper compared to 225.0kt grading 2.03% copper mined underground during the fourth quarter of 2017;

    • During first quarter 2018, 316.1 kt of ore was processed at an average grade of 1.76% copper resulting in 4,845 tonnes of copper production after metallurgical recoveries that averaged 87.3% over the period;

    • 4,096 tonnes of copper in concentrate sold during the quarter.

  • Vermelhos Mine Development advancing towards first production
    • During the first quarter, total development of 961 meters completed, including 240 meters of primary ramp development, 549 meters of secondary development and 172 meters of auxiliary ramp development accessing the UG1 production area. Additionally, 266 meters of total raise bore drilling was completed during the quarter;

    • Total development completed since project commencement of 2,678 meters, including 1,081 meters of primary ramp development.

  • Exploration Activitiesnew discoveries in the making
    • Pilar District
      • Exploration activities continue to be focused on the new discovery within the North Extension, testing for up-dip extensions of the P1P2W mining area, and extensions to the Deepening. All Pilar exploration targets are within or adjacent to existing Pilar underground mine infrastructure. Currently seven underground and one surface drill rigs are operating at Pilar.

    • Surubim District
      • Drilling activities are focused on evaluating new target areas adjacent to the Surubim open pit mine. Currently four exploration drill rigs are operating within the District.

    • Vermelhos District
      • With infill drilling largely completed, drilling has shifted focus towards the exploration of new targets as well as down-dip extensions of the main Vermelhos ore bodies to the north and up-dip extensions of the main Vermelhos ore bodies to the south. The copper oxide exploration program also remains ongoing. Currently five exploration drill rigs are operating at Vermelhos.

    • Regional Programs
      • Subsequent to the end of the quarter, the Company commenced its 24,000 line-kilometer regional airborne geophysical survey. The survey is expected to take approximately four months to complete. Data processing commenced contemporaneously with the start of the program.

  • Corporate Highlights – long term concentrate sales agreement in place
    • The Company entered into a long-term concentrate sales agreement (evergreen agreement renewed annually with minimum term of five calendar years) with Paranapanema S.A. ("Paranapanema").


The Company's production, cash cost and capital expenditure guidance for 2018 remains unchanged. Additional information is outlined below and further detailed in the Company's press release dated January 9, 2018.

Production for the year is heavily weighted towards the second half of the year in part due to the commissioning of the Vermelhos Mine, currently anticipated during the fourth quarter, as well as Pilar and Surubim mine resequencing. Cash cost guidance for 2018 assumes a USD:BRL foreign exchange rate of 3.20, gold price of US$1,250 per ounce and silver price of US$17.50 per ounce. C1 Cash Cost guidance for 2018 has been updated to include treatment and refining charges ("TC/RCs"), offsite transportation costs and certain tax benefits that are passed through to customers on invoicing. These adjustments were not included in prior C1 Cash Cost disclosure.

Capital Expenditures:

The Company's capital expenditure guidance for 2018 reflect the acceleration of the Vermelhos mine and a significant expansion of the Company's 2017 exploration programs. Additional investments in the Pilar underground mine and supporting infrastructure are being made during 2018 in preparation for a longer mine life than previously envisioned.


Non-IFRS measures

Financial results of the Company are prepared in accordance with IFRS. The Company utilizes certain non-IFRS measures, including C1 cash cost of copper produced (per lb), EBITDA, net debt and working capital, which are not measures recognized under IFRS. The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

C1 Cash Cost of copper produced (per lb.)

C1 Cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development costs and by-product credits, divided by the copper pounds produced. C1 cash costs reported by the Company include treatment, refining charges offsite costs, and certain tax credits relating to sales invoiced to the Company's Brazilian customer on sales.  By-product credits are calculated based on actual precious metal sales (net of treatment costs) during the period divided by the total pounds of copper produced during the period. C1 cash cost of copper produced per pound is a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company's operating mining unit, and is widely reported in the mining industry as benchmarks for performance, but does not have a standardized meaning and is disclosed in addition to IFRS measures.

Earnings before interest, taxes, depreciation and amortization (EBITDA)

EBITDA represents earnings before interest expense, income taxes, depreciation, and amortization. Adjusted EBITDA includes further adjustments for non-recurring items and items not indicative to the future operating performance of the Company. The Company believes EBIDTA and adjusted EBIDTA are appropriate supplemental measures of debt service capacity and performance of its operations.

Adjusted EBIDTA is calculated by removing the following income statement items:

  • Gain on debt settlement
  • Foreign exchange gain (loss)

Working capital

Working capital is determined based on current assets and current liabilities as reported in the Company's consolidated financial statements. The Company uses working capital as a measure of the Company's short-term financial health and operating efficiency.

Net Debt

Net debt is determined based on cash and cash equivalents, restricted cash and loans and borrowings as reported in the Company's consolidated financial statements. The Company uses net debt as a measure of the Company's ability to pay down it's debt.


The Company will hold a conference call on Tuesday, May 8, 2018 at 11:30am Eastern time (8:30am Pacific time) to discuss these results.
