Vancouver, British Columbia – Ero Copper Corp. (“Ero” or the “Company”) (TSX: ERO) is pleased to announce the production results for the three and twelve month period ended December 31, 2019 for its 99.6% owned Vale do Curaçá (“Curaçá Valley”) Property located in Bahia State, Brazil and its 97.6% owned NX Gold Mine, located in Mato Grosso State, Brazil.  The Company’s financial results for the full year and fourth quarter of 2019 will be published on Thursday, March 12, 2020 after the close of the Toronto Stock Exchange.

2019 Production Highlights:

• Total annual copper production at the Curaçá Valley operations of 42,318 tonnes compared to 30,426 tonnes produced in 2018, a 39% year-on-year increase in production, significantly exceeding original 2019 production guidance of 36,000 to 38,000 tonnes of copper.
• Total annual gold and silver production at the NX Gold Mine of 30,434 ounces of gold and 19,641 ounces of silver.

2020 Outlook Highlights:

• Annual production guidance for the Curaçá Valley operations of 41,000 to 43,000 tonnes of copper in concentrate;
• C1 cash cost^[1] guidance of US$0.85 to US$0.95 per pound of copper produced and capital expenditure guidance of US$74.0 million^[2];
• An additional US$28 million^[2] to fund the 2020 exploration program in the Curaçá Valley.  The program is highlighted by 172,000 meters of planned exploration drilling through September 2020, an annualized rate of approximately 230,000 meters, of which approximately 60% is planned for regional exploration including drill testing of new greenfield targets identified during the Company’s airborne geophysical survey and ongoing data analysis. This compares to approximately 235,000 meters drilled during 2019 of which only 23% was allocated to regional exploration.
• Annual production guidance for the NX Gold Mine of 38,000 to 40,000 ounces of gold at C1 cash costs^[1] of US$475 to US$575 per ounce of gold produced. Annual capital expenditure guidance for the NX Gold Mine of US$6 million plus US$3.5 million^[2] in ongoing exploration expenditures.

Commenting on the 2019 production results and 2020 outlook, David Strang, President & CEO of Ero stated, “Our business strategy has and continues to be focused on achieving near-term organic production growth, at first quartile production costs, while increasing the foundational long-term copper production base of the Curaçá Valley through aggressive exploration and discovery. As we look back at the tremendous growth of Ero over the past two years, I’d like to recognize the work throughout our organization that has contributed to another year of record copper production. Highlights of 2019 include significant year-on-year increases in tonnes mined and processed, copper grades and metallurgical recoveries, all of which contributed to a 39% increase in copper produced when compared to 2018.

As we look forward to 2020 in the Curaçá Valley, we expect another strong operational year with mill head-grades of greater than 2.00% copper resulting in C1 cash costs well below US$1.00 per pound of copper produced. Additionally, we are executing on our mill improvement plans including the completion of the HIG Mill installation and commissioning of the recently installed ore sorting plant.  

Our NX Gold operations faced headwinds during the second half of 2019 as the team successfully navigated the transition from mining the Brás and Buracão veins to mining of the new Santo Antonio vein. While the mine realized lower fourth quarter production than previously planned, normalized production levels of greater than 3,000 ounces per month were achieved by December. Underscoring this achievement, we expect 2020 production to total nearly 40,000 ounces of gold at C1 cash costs between US$475 and US$575 per ounce of gold produced.”

2019 PRODUCTION RESULTS

• Mining & Milling Operations – another record year of copper production
  • Total of approximately 2.4 million tonnes of ore grading 1.93% copper mined and processed during the year producing 42,318 tonnes of copper in concentrate after average metallurgical recoveries of 90.5%;
  • Fourth quarter mill throughput of 589,065 tonnes grading 2.16% copper producing 11,526 tonnes of copper in concentrate after metallurgical recoveries that averaged 90.7% during the period;
  • The NX Gold Mine processed 158,275 tonnes of ore grading 6.98 grams per tonne gold, resulting in the production of 30,434 ounces of gold and 19,641 ounces of silver as by-product after metallurgical recoveries that averaged 85.7% during the twelve month period ended December 31, 2019.  

2020 PRODUCTION OUTLOOK

Copper production from the Curaçá Valley operations for 2020 is expected to come from ore mined from the Pilar and Vermelhos underground mines. Production from the Pilar Mine is expected to contribute a total of approximately 1.4 million tonnes grading 1.40% copper while production from the Vermelhos Mine is expected to contribute a total of approximately 750,000 tonnes grading 3.50% copper resulting in a blended mill head grade of approximately 2.15% copper.

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), C1 cash costs of gold produced (per ounce) 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.

C1 cash cost of gold produced (per ounce)

C1 cash cost of gold produced (per ounce) is the sum of production costs, net of capital expenditure development costs and silver by-product credits, divided by the gold ounces produced.  By-product credits are calculated based on actual precious metal sales during the period divided by the total ounces of gold produced during the period.  C1 cash cost of gold 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.

Cautionary Notes Regarding Mineral Resource and Reserve Estimates In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and are classified in accordance with the CIM Standards.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with Measured or Indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an Inferred mineral resource will be upgraded to an Indicated or Measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, Inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.
