Ero Copper Corp. Guidance – Increasing 2018 Production Forecast

January 9, 2018

Vancouver, British Columbia – Ero Copper Corp. (TSX: ERO (the “Company”)) is pleased to provide the following production and cost guidance for 2018. Key highlights are as follows:

  • 2018 production guidance of 25,500 to 27,500 tonnes of contained copper, a meaningful improvement as compared to the 2018 forecast outlined in the 2017 Vale do Curaçá Technical Report dated September 7, 2017 (the “Technical Report”)
  • Production start up at the Vermelhos Mine in the fourth quarter of 2018, including first production from the main Vermelhos orebody, previously expected late in the first quarter of 2019
  • C1 Cash Cost guidance of US$1.30 to US$1.40 per pound of copper produced at updated USD:BRL foreign exchange rate assumption of 3.20 vs. Technical Report assumption of 3.60
  • Capital expenditure guidance of approximately US$96 million, includes bringing forward development capital to 2018 in support of the accelerated Vermelhos Mine start up and a significantly expanded exploration program of approximately US$20 million focused on high-grade discovery throughout the Curaçá Valley
  • 2018 exploration program highlighted by the airborne electromagnetic (“EM”) and gravity survey (expected to commence during the first quarter of 2018) and 86,000 meters of planned drilling

David Strang, President and CEO commented, “As we close out what has been a transformational year for the Company, we are very excited about 2018 in all aspects of production, mine development and exploration. Our copper production outlook for 2018 reflects our focus on aggressively growing copper production and utilizing the operational leverage of our under- utilized mill and processing facilities. The increased production reflects the outperformance of Vermelhos development achieved to date and the expansion of Surubim operations – key initiatives undertaken and realized during 2017. We now fully expect the Vermelhos Mine to begin production during the fourth quarter.

In addition to the positive developments in production, our expanded exploration and drilling program of approximately US$20 million should position the Company to target high-grade copper mineralization throughout the Curaçá Valley using modern exploration techniques. This program includes one of the largest airborne electromagnetic and gravity surveys to be undertaken in Brazil. We expect the airborne survey to be substantively completed during the first half of 2018. 

While capital expenditures have increased relative to the 2017 Technical Report, these increases are predominately related to the accelerated start up of the Vermelhos Mine and the expanded exploration program. In addition, we are making increased capital investments in certain areas of the Pilar Mine in preparation for a longer mine life including in advancing ventilation and development” Mr. Strang concluded.


Copper production guidance for 2018 is weighted towards the second half of the year in part due to the commissioning of the Vermelhos Mine during the fourth quarter.  Production from the Pilar Mine is expected to contribute approximately 1.3 million tonnes of ore grading 1.80% copper, while the extension of Surubim Phase 2 is expected to contribute approximately 600,000 tonnes grading 0.90% copper from open pit operations. Commissioning of the Vermelhos Mine during the fourth quarter is expected to contribute an additional 90,000 tonnes of ore grading approximately 2.50% copper, resulting in a blended head grade for the full year of between 1.50% and 1.60% copper.

(1)  Guidance is based on certain estimates and assumptions, including but not limited to, mineral reserve estimates, grade and continuity of interpreted geological formations and metallurgical performance. Please refer to the Company’s SEDAR filings for complete risk factors.


The Company’s 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.

Relative to the Technical Report, full year cash costs in 2018 are expected to increase to reflect the start-up staffing requirements of the Vermelhos Mine which were previously amortized over a full-year of Vermelhos production in 2019, a higher portion of production from open pit operations (none envisioned in the Technical Report), and an adjustment in foreign exchange rate assumptions. C1 Cash Cost guidance 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 C1 Cash Costs in the Technical Report.

The Company’s capital expenditure guidance for 2018 assumes a USD:BRL foreign exchange rate of 3.20 and has been presented below in USD millions.

Relative to the Technical Report, full year capital expenditures are expected to increase due to the acceleration of the Vermelhos Mine and a significant expansion of the exploration program. 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.) 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. By-product credits are calculated based on actual precious metal sales (net of TC/RCs) during the period divided by the total pounds of copper produced during the period.


Ero Copper Corp, headquartered in Vancouver, B.C., is focused on copper production growth from the Vale do Curaçá Property, located in Bahia, Brazil. The Company’s primary asset is a 99.5% interest in the Brazilian copper mining company, Mineração Caraíba S.A. (“MCSA”), 100% owner of the Vale do Curaçá Property with over 37 years of operating history in the region.  The Company currently mines copper ore from the Pilar underground and the Surubim open pit mines. In addition to the Vale do Curaçá Property, MCSA owns 100% of the Boa Esperanҫa development project, an IOCG-type copper project located in Pará, Brazil.  Additional information on the Company and its operations, including Technical Reports on both the Vale do Curaçá and Boa Esperanҫa properties, can be found on the Company’s website ( and on SEDAR (
