• First quarter gold and silver production at the NX Gold Mine of 10,119 ounces of gold and 6,359 ounces of silver at C1 Cash Costs^* of $486 per ounce of gold produced;

• Generated $39.3 million in Adjusted EBITDA^* and $25.1 million in cash flow from operations during the three month period ended March 31, 2019;

• Adjusted net income attributable to owners of the Company^* of $15.7 million ($0.17 per share on a diluted basis) during the three month period ended March 31, 2019;

• Ended the first quarter with cash position of $22.1 million; and,

• Reiterated full year production, capital and operating cost guidance for 2019.

“Our operational results from the first quarter of 2019 are in line with our expectations and demonstrate strong overall performance during the period. The results are highlighted by a significant quarter-on-quarter increase in grades mined and processed as we started to mine the main orebodies of the Vermelhos Mine during the period. The increase in mill head-grade, paired with several recently completed low-cost and high-value milling and flotation improvement initiatives resulted in increased metallurgical recoveries which contributed to the 8% improvement in C1 Cash Costs per pound of copper produced when compared to the fourth quarter of 2018 and reflects the continued great work by our team at Mineração Caraíba.

At Vermelhos, production from the first operating stopes of the main orebodies commenced during the period, resulting in a 34% quarter-on-quarter improvement in grades mined. With two quarters of production at Vermelhos now complete, we are extremely pleased with the operational performance of the mine. At Pilar, a decline in grades was anticipated due to planned stope sequencing, and we expect grades to improve through the balance of the year. During the period, we also repositioned our open pit mining fleet and commenced operations at R22W, which we expect will continue to ramp up production through the second quarter.

Now that production from Pilar and Vermelhos is on stable footing, we have continued to increase our exploration efforts throughout the Curaçá Valley where we now have 24 drill rigs operating. While the majority of the ongoing exploration programs are focused in and around our existing mines in preparation of our updated National Instrument 43-101 compliant technical report, expected to be completed towards the end of the third quarter or early fourth quarter, we have now commenced drilling targets within the Vermelhos and Pilar Districts identified during the Company’s regional airborne survey and subsequent data compilation and prioritization work.

At our high-grade NX Gold Mine, production of 10,119 ounces of gold and 6,359 ounces of silver during the period was in line with 2018 production levels. Mill improvements completed during the period combined with an increase in mill head-grades contributed to a 10% overall improvement in C1 Cash Costs to $486 per ounce of gold produced – a fantastic achievement for our NX Gold team,” commented David Strang, President & CEO of Ero.

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

OPERATIONS & EXPLORATION HIGHLIGHTS

• Mining & Milling Operations – strong start to 2019
  • 530,133 tonnes of ore grading 2.19% copper processed during the first quarter producing 10,645 tonnes of copper in concentrate after average metallurgical recoveries of 91.8%;
    
  • Commenced mining of the Vermelhos main orebodies, with 139,143 tonnes mined grading 3.71% copper mined during the period contributing to a significant increase in total grades mined and processed;
    
  • The Company’s 97.6% owned NX Gold Mine processed 38,717 tonnes of ore grading 8.76 grams per tonne gold, resulting in the production of 10,119 ounces of gold and 6,359 ounces of silver as by-product after metallurgical recoveries that averaged 92.8% during the first quarter of 2019.
    
• Exploration Activities – advancing new discoveries
  • Vermelhos District
    • Exploration in the Vermelhos District, where 11 drill rigs are currently operating, is focused on in and near-mine expansion as well as drilling a north-northeast mineralized trend encompassing the Vermelhos Mine, East Zone, N8 Deposit and several high-priority regional targets located south and to the north of the Vermelhos Mine – a combined strike length of approximately 5.5 kilometers.
  • Pilar District
    • Exploration activity within the Pilar District, where 13 drill rigs are currently operating, continues to focus on previously announced discoveries of the West Limb and Deepening Extension zones. Recent drilling has identified a high-grade zone of mineralization within the southern portion of the West Limb and newly identified and now digitized data continues to augment exploration activities at Pilar. In addition, the Company continues to drill test several regional targets within the Pilar District south of the Pilar Mine identified during the Company’s data compilation and targeting work.
  • NX Gold Mine
    • At the NX Gold Mine, where 6 drill rigs are currently operating, exploration efforts are focused on a recently announced new zone of mineralization. This new zone of mineralization is located between and on-trend of the Bras and Buracão veins. To-date, mineralization has been delineated over approximately 400 meters in strike-length and approximately 200 meters down-dip and remains open to depth.
  • Regional Programs
    • With the Company’s regional data compilation and targeting work now substantively completed, the Company has prioritized and is currently drilling regional exploration targets proximate to the existing operations. An order for a mobile truck-mounted reverse-circulation drill rig has been placed with our primary drill contractor that will used to expedite testing of regional targets distal to the Pilar and Vermelhos mines.

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), EBITDA, Adjusted EBITDA, Adjusted net income (loss), Adjusted earnings (loss) per share, 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.

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.

Earnings before interest, taxes, depreciation and amortization (EBITDA) and Adjusted 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 EBITDA and adjusted EBITDA are appropriate supplemental measures of debt service capacity and performance of its operations.

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

- Gain on debt settlement
- Foreign exchange gain (loss)
- Share based compensation

Adjusted Net Income (Loss) and Adjusted Earnings (Loss) Per Share

The Company uses the financial measure “Adjusted net income (loss)” and “Adjusted earnings (loss) per share” to supplement information in its consolidated financial statements. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use this information to evaluate the Company’s performance. The Company excludes non-cash and unusual items from net earnings to provide a measure which allows the Company and investors to evaluate the operating results of the underlying core operations.

During the period, the following non-cash or unusual adjustments to calculated adjusted net income (loss):

- Unrealized foreign exchange gain (loss) on USD denominated debt in MCSA
- Unrealized foreign exchange gain (loss) on derivatives contract

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 its debt.

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.

CONFERENCE CALL DETAILS

The Company will hold a conference call on Wednesday, May 8, 2019 at 11:30am Eastern time (8:30am Pacific time) to discuss these results.

This press release should be read in conjunction with the complete condensed consolidated interim financial statements and management’s discussion and analysis (“MD&A”) for the three month period ended March 31, 2019 available on the Company’s website www.erocopper.com and on SEDAR (www.sedar.com).
