Vancouver, British Columbia – Ero Copper Corp. (TSX: ERO) (“Ero” or the “Company”) today announced its financial results for the three and nine months ended September 30, 2017. Management will host a call tomorrow, Wednesday November 15, 2017, at 7:00 a.m. Eastern time to discuss the quarterly results. Dial in details for the conference call can be found near the end of this news release.

HIGHLIGHTS

• Third quarter copper production of 5,793 tonnes at a C1 cash cost of $1.37 per pound of copper; and,
• During the nine month period ended September 30, 2017, total copper production of 14,799 tonnes at a C1 cash cost of $1.42 per pound of copper.
• Third quarter net income attributable to owners of the Company of $18.3 million ($0.29 per share on a diluted basis). Results include an extraordinary $14.8 million gain related to deferred income tax recovery.
• Expect to exceed 2017 production forecast of 19,022 tonnes of copper by year end.

“This was a good quarter for Ero Copper as we continued to achieve our production, safety and development goals while maintaining our focus on aggressive exploration throughout the Curaçá Valley” commented David Strang, President & CEO of Ero Copper.

“At Pilar and Suçuarana Norte mines and the Caraíba Mill, the successful execution from the restart of operations in the first quarter of 2017 through to these third quarter results is a true testament to the quality of our operating team in Brazil. At the Vermelhos Mine – a key value driver for the Company in the near-term – the continued ramp development at significantly faster rates than previously envisioned should result in an improvement in our 2018 outlook as we hope to bring Vermelhos into production ahead of schedule.”

On exploration, the results achieved to date within the Pilar and Vermelhos mines, including recent intercepts that rank among the top-five intercepts ever drilled at Vermelhos on a grade-meter basis, reinforce the Company’s focus on targeting high-grade mineralization throughout the Curaçá Valley. In addition, the continued success of the near-mine exploration programs at Pilar, including in the Deepening Zone, gives us confidence in the longer-term production potential from the Pilar Mine.”

“The successful completion of our Initial Public Offering and listing of the Company’s common shares on the Toronto Stock Exchange in October 2017 provides us with sufficient capital to complete the development of the Vermelhos Mine and effect our organic growth strategy with continued aggressive exploration programs in 2018,” Mr. Strang concluded.

  • During the third quarter 2017, 534.0 thousand tonnes (“kt”) of ore was mined at a combined grade of 1.23% copper, comprised of 227.6 kt of ore grading 2.08% copper from underground operations and 306.3 kt of ore grading 0.60% from open pit operations;
  • During the third quarter of 2017, 540.9 kt of ore was processed at an average grade of 1.23% copper resulting in 5,793 tonnes of copper production after metallurgical recoveries that averaged 87.1% over the period;

  • At Suçuarana North, mineralization has continued beyond the previously envisioned pit limits, allowing open pit mining operations to continue while Surubim prepares for full restart of operations.
• Vermelhos Mine Development – advancing key development milestones
  • During the third quarter 2017, total development of 645 meters completed, including 310 meters of primary ramp development, 253 meters of secondary development and 83 meters of auxiliary ramp development to access the UG1 Target;
  • Total development completed during the nine month period ending September 30, 2017 of 895 meters, including 535 meters of primary ramp development since May at an average rate of 107 meters per month, well ahead of the ramp development rate envisioned in the NI 43-101 Technical Report of 75 meters per month;
  • 28 kilometer powerline to the mine site completed;
  • Completion of Phase 1 surface infrastructure with Phase 2 advancing on schedule;
  • Orders placed for long-lead time equipment.
• Exploration Activities – advancing “Super Pods”
  • Pilar District
    • Exploration activities focused on the South Extension and the high-grade infill drilling program including a newly discovered lens within the “Deepening Zone” located in the Pilar underground mine, where several significant intercepts were previously reported.
  • Vermelhos District
    • Exploration activities focused on infill drilling required for stope definition and detailed mine planning, with several significant intercepts including 20.0 meters grading 12.21% copper and 22.0 meters grading 9.60% copper, among the top-five intercepts on a grade-meter basis drilled at the Vermelhos mine to date.
  • Corporate Highlights – Successful completion of the Company’s Initial Public Offering and listing on the Toronto Stock Exchange (“TSX”)
    • Issued an aggregate of 13,492,317 common shares (including 3,492,317 shares issued in connection with the full exercise of the over-allotment option by the underwriters) at C$4.75 per common share, for total proceeds of approximately $50.9 million. Proceeds were subject to a 6% fee paid to the underwriters;
    • The common shares commenced trading on the TSX under the symbol “ERO” on October 19, 2017;
    • Working capital deficit decreased to $4.1 million in third quarter 2017 from $23.1 million in the second quarter of 2017 primarily as a result of a tax amnesty program in Brazil that allows for the deferral of certain taxes payable, which has resulted in the classification of current taxes payable to non-current taxes payable. In addition, the government program allows companies to offset part of taxes payable with the use of tax non-capital loss carry-forward balances. As of September 30, 2017, $14.8 million was utilized to reduce taxes payable.

NOTES

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.) 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 costs reported by the Company exclude treatment, refining charges and offsite costs. 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.

CONFERENCE CALL DETAILS

The Company will hold a conference call on Wednesday, November 15, 2017 at 7:00am Eastern time (4:00am Pacific time) to discuss these results.

This release should be read in conjunction with the complete unaudited consolidated financial statements and management’s discussion and analysis (“MD&A”) for the three months ended September 30, 2017 available on the Company’s website www.erocopper.com
