Nevsun Provides 2018 Outlook and Guidance

VANCOUVER, Jan. 31, 2018 /PRNewswire/ - Nevsun Resources Ltd. (TSX:NSU) (NYSE AMERICAN:NSU) (Nevsun or the Company) today provided its outlook and guidance for 2018. Unless otherwise noted, all dollar amounts are in millions of US dollars. 

2018 Outlook Highlights

• Achieve top quartile safety performance at all operations
• Invest $50 to $60 million advancing the Timok Upper Zone Copper-Gold Project
• Produce 210 to 240 million pounds¹ of zinc at:
• C1 cash cost of $0.70 to $0.90 per payable pound sold with copper on a co-product basis; and
• C1 cash cost of $0.60 to $0.80 per payable pound sold with copper on a by-product basis²
• Produce 20 to 30 million pounds¹ of copper at:
• C1 cash cost of $1.55 to $1.75 per payable pound sold on a co-product basis
• Invest $15 million including 12.5 km of follow-up drilling on highly prospective Upper Zone targets
• Suspend the dividend and redeploy capital to growth

Peter Kukielski, President and CEO commented, "In 2018 Nevsun will drive value by advancing the high-grade Timok Upper Zone project, one of the world's best copper development projects.  We will complete our prefeasibility in Q1 2018, significantly advance the definitive feasibility, and follow up on last year's successful Upper Zone exploration program."  Mr. Kukielski continued, "At Bisha, zinc and copper production are expected to increase, taking advantage of a strong base metals market.  The resulting cash flow and dividend redeployment will bolster an already strong balance sheet enabling growth from Timok development and exploration."

Timok Copper-Gold Project

The Company expects to invest between $50 and $60 million (excluding exploration) at the Timok Upper Zone Project for 2018.  Key activities include:

• Complete the in-progress pre-feasibility study in Q1-2018 including a maiden reserve estimate;
• Commence and advance the definitive feasibility study work for completion in the first half of 2019;
• Start development of the exploration decline once all permits are received;
• Continue land acquisition to cover the majority of the Upper Zone mine footprint;
• Complete the condemnation drilling program to assist with infrastructure planning; and
• Advance other critical path activities including the environmental and social impact assessment.

Commencement of exploration decline work is contingent on permitting by the State of Serbia. The Company was expecting the exploration decline permit in Q4 2017 and is now collaborating with the State of Serbia to understand the source of the delay and to expedite approval. An estimated $15 million of work on the exploration decline is budgeted in 2018.

Bisha Zinc-Copper Mine

In 2018 the principal source of mill feed is primary ore sourced from the Bisha main pit. This is in contrast to the second half of 2017 when zinc-only stockpiles were processed.  Stockpiles of zinc-only ore remain available for processing, if required. At current gold prices there are no plans to monetize precious metal stockpiles in 2018.

Bisha expects to achieve improved zinc and copper recoveries from primary ore in 2018. An ongoing program of metallurgical improvement is yielding improvements in copper recoveries at Bisha. Recent work has focused on reagent optimisation and further work is planned on water quality and tighter pH control within the flotation circuit. Processing of stockpiled zinc-only ore, which adversely impacted 2017 overall metallurgical performance, is not planned in 2018.   

Planned total material movement (ore plus waste) of 21.2 million tonnes is up 15% from 2017.  To achieve this increase, the mine will take advantage of recently purchased additional heavy mining equipment, shortened haul distances from planned waste dumping in the now exhausted north portion of the pit, and continue to use contractors to enhance maintenance capacity and improve fleet reliability. 

Capital investment at Bisha is estimated at $15 million for 2018 including $3 million for continuation of studies investigating the underground potential and $12 million for general sustaining capital.

Exploration

The Company is investing $5 million in exploration for the Upper and Lower Zone projects during 2018. This budget includes drilling approximately 12,500 metres of Upper Zone exploration.  Drilling will target new high grade, high sulphidation mineralization near the Timok Upper Zone, building on the promising exploration results announced in January 2018. 

For the Timok Lower Zone porphyry exploration, the $20 million agreed work program with Freeport-McMoRan Exploration Corporation ("Freeport") will be completed in 2018 with the final $1 million of this program 100% funded by Nevsun. Freeport, the joint venture partner on the Lower Zone, continues to work with the Company to design and execute the next phase of the Lower Zone work program which would be funded pro-rata by the partners.

The Company will drill approximately 16,000 metres at its 100% owned exploration projects in Serbia and Macedonia at a cost of $4 million. The exploration costs at Tilva in Serbia are predominantly funded by Rio Tinto as part of their earn-in.

In 2018 a budget of $7 million for 15,000 metres of exploration drilling is planned at Bisha. Work is targeting new shallow near-mine copper, gold and silver discoveries, and the work programs will include diamond drilling, ongoing surface and borehole geophysics, and target generation. 

Dividend Policy and Capital Requirements

The Board of Directors has completed the review of its dividend policy announced in early December 2017. Following the January 17, 2018 dividend payment, the Company will suspend dividend payments to redeploy the capital to the high-grade Timok copper-gold project in Serbia. Nevsun has determined that the development of the Timok Upper Zone represents, by far, the Company's best allocation of capital.

The Company will continue to advance its financing activities for the Timok project in 2018. The Company is in early stage discussions with project finance providers and expects to advance these discussions on release of the Timok pre-feasibility study. In parallel with these discussions, the Company is currently evaluating options for sourcing additional capital, including equity, convertible debt, precious metal streaming, and strategic partnerships.
