Nevsun Announces First Quarter 2018 Financial Results - With Strong Operational Performance at Bisha

Nevsun Resources Ltd. (TSX:NSU) (NYSE AMERICAN:NSU) ("Nevsun" or "the Company") is pleased to report its financial results for the three months ended March 31, 2018. Unless otherwise noted all financial results are in millions of US dollars.

Q1 2018 Highlights

  • Produced 71.6 million pounds of zinc and 8.9 million pounds of copper at Bisha
  • Sold 53.4 million pounds of payable zinc in concentrate and 7.8 million pounds of payable copper in concentrate
  • Costs below guidance with C1 cash costs(2) of $0.58 per payable pound of zinc sold on a by-product basis
  • Improved both zinc and copper recoveries at Bisha:
    • Zinc recovery improved by 8.5% to 81.1%
    • Copper recovery improved by 34.1% to 61.5%
  • Strong operating performance resulted in cash balance increasing from $125 million to $150 million during the quarter
  • Released the results of the Timok pre-feasibility study ("PFS") which demonstrated the project's sector-leading returns, with an after-tax NAV8% of $1.8 billion and IRR of 80% at $3.15 per pound copper
  • Received the Timok exploration decline permit; all approvals now in place to begin construction in Q2 2018
  • Completed all drilling related to the $20 million Timok Lower Zone work program which highlighted the deposit's potentially significant scale and impressive grades; resource statement to be released in mid 2018
  • Discovered high sulphidation epithermal ("HSE") mineralization approximately 500 metres to the east of the Upper Zone

"We are off to an excellent start in 2018 as we benefit from the strong foundations that were laid at both Bisha and Timok in 2017. The release of the PFS on the Timok Upper Zone was a significant milestone for the Company as it further de-risked the project and highlighted its exceptional economics. In parallel, we secured our decline permit, and through the collaborative process we strengthened our relationship with the Serbian government. We now look forward to a busy Q2 as we begin construction of the decline, launch the feasibility study and release the much-anticipated initial resource statement for the Lower Zone," said Peter Kukielski, Chief Executive Officer.

Mr. Kukielski continued: "Bisha had its best quarter since the beginning of the zinc phase. A second consecutive quarter of material movement of over 5 million tonnes in the mine enabled the plant to exclusively process primary ore. Together with trials of new reagents, there was a step-change in recoveries and record zinc sales in the quarter. The resulting increase in our cash balance highlighted the importance of Bisha as a cash generator. The improvements also support the work we are doing on potentially extending the mine life beyond the current plan."

Timok Project Update

In Q1 2018, the Company released the results of the PFS for the Timok Upper Zone copper-gold project in Serbia. The PFS confirmed the extraordinary value of the Timok Project, a high-grade, high return, fully executable copper project in a supportive jurisdiction. The PFS reflected an after-tax NAV8% of $1.8 billion and IRR of 80% at $3.15 per pound copper with a payback period of less than one year based on an initial reserve of 27 million tonnes at 3.3% copper and 2.1 grams per tonne gold.

Extensive work was performed in the quarter on the project implementation schedule in collaboration with the Republic of Serbia to better understand the permitting process and requirements. As a result of this work, the Company gained valuable insights into the permitting regimen in Serbia under the terms of its mining law, and on February 27, 2018 the Company received the exploration decline permit. Through this process the Company acquired knowledge and relationships that will serve the Company well as it moves towards securing additional permits for the Timok Project. The Company is in the process of finalizing the contract tendering process to commence the decline construction activities in Q2 2018. The Company has acquired 100% of the land required for development of the decline and 53% of the required private land for construction of the project as at March 31, 2018.

At the Lower Zone, the Company completed the drilling campaign related to its $20 million work commitment, which continued to demonstrate the impressive copper grade, continuity and thickness of mineralization in the Lower Zone. To date, 84 drill holes have been drilled within the Lower Zone footprint, of which 78 drill holes comprising approximately 90,571 meters have intersected the deposit or its margins. The geometry of the Lower Zone remains to be fully defined, however current dimensions of the mineralized zone are approximately 2,000 metres long by 1,100 metres wide by 1,400 metres high. The mineralization comes to within 700 metres of surface at its south-eastern margin and extends to over 2,200 metres depth to the northwest, where it remains open. Highlighted assays from the final drill holes included 1.00% Cu and 0.20g/t Au (1.14% Cu equivalent) over 556.8 metres starting at 1,310 metres in TC170177 which included 1.45% Cu, 0.32g/t Au (1.67% Cu equivalent) over 177.0 metres. The company will release a Lower Zone resource statement in Q2 2018.

Regional drilling focused on searching for new high grade Upper Zone-style mineralization. Significant intersections of high sulphidation epithermal mineralization were made approximately 500 metres to the east of the Upper Zone in a 250 by 250 metre area, including hole TC170189 which returned 2.93% copper and 2.54 g/t gold over 27.0 metres at a depth of 396 metres. Follow up drilling will take place in 2018.

Bisha Mine Update

Bisha maintained total quarterly material movement above 5 million tonnes for the second consecutive quarter in Q1 2018. This sustained improvement in mine performance reflects the deployment of new heavy mining equipment ("HME"), improving HME availability and the implementation of a plan for in-pit waste dumping with favourable impacts on hauling distance. The mine is expected to continue to benefit from the in-pit waste dumping for the next 12 months. Exceptions to the mine plan required in 2017 to alleviate processing difficulties for certain ore types, have now been largely corrected. This resulted in a decrease in the stripping ratio from Q4 2017 and will ensure adequate primary ore supply in support of achieving 2018 mine production targets.

On processing, Bisha achieved breakthrough results on the key metallurgical challenge that the mine has faced since the commencement of the zinc phase – copper-zinc selectivity – during a 31-day plant trial using alternate reagent schemes. Both zinc and copper recoveries in Q1 2018 improved upon Q4 2017 results at 81.1% and 61.5%, respectively, compared to 72.6% and 27.4% in the Q4 2017 period. The Company is currently installing upgrades on the plant that, once completed in Q2 2018, will allow for consistent application of the revised reagent scheme which is expected to significantly improve both copper recovery and copper concentrate grades going forward. As a result of the improved recoveries, Bisha is currently tracking toward the higher end of 2018 production guidance and toward the lower end of cost guidance. Based on this performance, the Company is confident that it will achieve 2018 guidance. Guidance will be reviewed if the modified processing approach results in a sustained improvement in recoveries over a more extended period.
