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, 2018 for its 99.6% owned Vale do Curaçá Property located in Bahia State, Brazil.  The financial results for the full year and fourth quarter of 2018 will be published on Thursday, March 14, 2019 after the close of the Toronto Stock Exchange.
2018 Production Highlights:

• Total annual copper production of 30,426 tonnes compared to 20,133 tonnes produced in 2017, a 51% year-on-year increase in production, and exceeding original 2018 production guidance by 15%; 
• Fourth quarter copper production of 12,104 tonnes of copper, a 55% quarter-on-quarter increase in production; and,
• Total annual gold and silver production at the Company’s 97.6% owned NX Gold Mine of 39,808 ounces gold and 24,573 ounces silver.

2019 Outlook Highlights:

• Annual copper production guidance of 36,000 to 38,000 tonnes;
• C1 Cash Cost guidance of US$1.00 to US$1.10 per pound of copper produced at USD:BRL foreign exchange rate of 3.70;
• Capital expenditure guidance of US$62.0 million;
• An additional US$20 million to fund the 2019 exploration program.  The program is highlighted by 130,000 meters of planned exploration drilling, comprised of 112,500 meters of near-mine exploration drilling (including continued exploration of the Vermelhos East Zone and Pilar West Limb), plus an additional 17,500 meters of planned greenfields exploration drilling to test high-priority regional exploration targets identified during the Company’s airborne geophysical survey.

Commenting on the 2018 production results and 2019 outlook, David Strang, President & CEO of Ero stated, “Our strategy for 2018 was to secure a long-term foundational copper production base for the operations in the Curaçá Valley.  With the ahead-of-schedule commissioning of the Vermelhos Mine in August, and consistent month on month production from the Pilar Mine, the Company has achieved that goal.  In addition, the mill throughput of 777,480 tonnes in the fourth quarter, an annualized equivalent throughput of 3.1 million tonnes, demonstrates that the mill is capable of operating consistently at its current deemed capacity limits of approximately 3.2 million tonnes per annum. 

As we look forward to 2019, we expect to build on the strong operational performance realized to date as we continue to increase total copper production, further reduce operating costs and implement several high-value optimization projects that were started during 2018. While ore production in 2019 is notionally forecast to be 2 million tonnes, we are focused on identifying opportunities to continue to increase mill throughput this year at each mining operation.

Further, our exploration programs are now focused on both lengthening mine life and increasing mill throughput.  We intend to build on the successes made in 2018 with the discoveries of the West Limb at Pilar and the East Zone at Vermelhos, by bringing each discovery into mineral reserves through aggressive in-fill and extension drilling.  In addition, we will also be evaluating and pursuing new regional targets generated from the 2018 airborne geophysical survey that will allow us to continue to grow our operational footprint in the Curaçá Valley.”

2018 PRODUCTION RESULTS

• Mining & Milling Operations – record year and quarter
  • Total of approximately 2.3 million tonnes of ore grading 1.56% copper mined and processed during the year producing 30,426 tonnes of copper in concentrate after average metallurgical recoveries of 86.3%;
  • Fourth quarter mill throughput of 777,480 tonnes grading 1.77% copper producing 12,104 tonnes of copper in concentrate after metallurgical recoveries that averaged 87.8% during the period;
  • Early commissioning of the Vermelhos Mine (approximately 4 months ahead of schedule) resulted in a total of 206,873 tonnes of ore grading 2.72% copper mined contributing to the annual production result, with 143,661 tonnes grading 2.77% copper mined during the fourth quarter;
  • The Company’s 97.6% owned NX Gold Mine processed 117,857 tonnes of ore grading 11.55 grams per tonne gold, resulting in the production of 39,808 ounces of gold and 24,573 ounces of silver as by-product after metallurgical recoveries that averaged 91.0% during the twelve month period ended December 31, 2018.  

2019 PRODUCTION OUTLOOK

Copper production in 2019 is expected to have a slight bias towards the first half of the year due to higher-grade stope sequencing at both the Pilar and Vermelhos underground mines as well as incremental production from the R22W open pit mine.  R22W is expected to augment underground production during the first half of the year (contributing approximately 250,000 tonnes of ore grading 0.50% copper).  Underground production from the Pilar Mine is expected to contribute a total of approximately 1.3 million tonnes grading 1.80% copper while underground production from the Vermelhos Mine is expected to contribute a total of approximately 500,000 tonnes grading 3.20% copper resulting in a blended head grade of approximately 2.00% copper for 2019.

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), which is not a measure recognized under IFRS. The Company believes that the measure, 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.
