Jaguar Mining Provides Management Update and Reports on Operating Progress

TSX: JAG

TORONTO, Aug. 20, 2018 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) today provided an update on recent management changes and progress on operating performance.

As previously announced, Benjamin Guenther was appointed Interim Chief Executive Officer effective August 15, 2018. Ben brings more than 40 years of mining industry experience, with extensive knowledge of mining in Brazil.

On behalf of Jaguar Mining's Board, Chairman Dick Falconer commented, "The entire Jaguar Mining Board would like to thank Ben for taking the role as Interim Chief Executive Officer through this critical period. We are confident that under his leadership, operational teams will take the right steps to improve Company performance including delivering on our targets for production, lower costs and increase operational cash flow.  We appreciate Ben's continued support as the Board conducts a thoughtful and comprehensive search for Jaguar's next CEO."

In addition, the Company has made progress on strengthening the senior operational team in Brazil with the recent appointment of Kevin Weston as Vice President Operations in July 2018. Mr. Weston is a Mining Engineer with nearly four decades of international gold and base metal mine management, as well as operational and gold processing experience. He has been successful in turning around challenging mining operations as well as achieving key targets during extended commissioning phases.

"As we focus on 2018 production and cost targets, we have made important changes to strengthen our operations team in Brazil. We are extremely pleased to welcome Kevin, who brings deep and proven experience with challenging operations, and look forward to his insight and positive impact across all of our mines," said Mr. Guenther. "Over the coming weeks, Kevin's top priority will be to focus on reviewing opportunities and implementing key changes at Turmalina to deliver on critical targets to drive improved performance."

The Company also takes this opportunity to provide an update on the strong performance at Pilar and its key priorities at Turmalina over the near-term.

Pilar Gold Mine Update

• Pilar Gold Mine ("Pilar") continues to see solid results and remains on track to achieve the higher end of production guidance in line with management expectations. Grades have more than doubled in the past two years, as the current working levels approach the higher-grade areas of orebodies BF and BFII.
• The mine management team performs well and is capable to adjust when challenging conditions are present. The solid performance of the team is the result of very good execution of the mine plan.
• Mine development and stope preparation inventories provide flexibility in maintaining consistent production rates.
• A new grade control program implemented at Pilar helped reduce dilution and improved reconciliations with reserve model.
• The orebody capacity provides confidence that the mine will continue to grow production in 2018 and a further growth is expected in 2019.

Turmalina Gold Mine Update

Geotechnical issues in the higher-grade area of Turmalina required modifying the mining sequence in the second quarter of 2018. This resulted in lower ore tonnage and grade as mine production was redirected to a lower grade area. Lack of mining flexibility required mining stopes prior to completing ore control drilling which contributed to a lower than expected grade profile.

In addition to a strengthened operating team with a Vice President of Operations in Brazil, management is focused on near-term priorities to deliver safe sustainable production performance and return to growing Turmalina's production to its historical profile.

Top near-term priorities at Turmalina include:

• Modifying the mining approach to minimize the number of unfilled open stopes. Converting from blind back stopes to cut-and-fill stoping below sill pillars to ensure minimal exposure from unfilled stope walls.
• Utilization of top down drilling to ensure better quality control on drilling, reduce dilution, improve mining recovery, and allow backfilling with waste rock.
• Strict adherence to backfilling in the stoping cycle to reduce unfilled open stopes.
• Use of better blasting techniques to reduce vibration into the rock mass.
• Improving ore control drilling, planning and execution to improve confidence in the ore production plan.
• Improving development planning and execution to give a high confidence in the mine production schedule.

The paste backfill plant has been commissioned and paste backfilling has begun in the upper levels of the Turmalina mine. In addition, a grade control program similar to Pilar has been implemented to reduce dilution.

The revised mine plan and schedule for the remainder of 2018 has been reviewed in detail which will allow Jaguar Mining to achieve the updated 2018 guidance of 80,000 to 85,000 ounces without any incremental costs.

The completion of these near-term priorities is critical to ensuring the flexibility and consistency in Turmalina's production plan. As it makes progress on these priorities, the Company expects in the near term that Turmalina will deliver:

• Improved gold production driving positive operational cash flow by the fourth quarter of 2018.
• Stabilized mine production over the coming quarters.
• Improved mine inventories over time to provide mining flexibility.
• Allow the mine to return to the historical higher production levels given the ore body capacity.

"Our top priority remains delivering key operational improvements at Turmalina as a path to returning to a growing and sustainable production profile more reflective of our large base of mineral resources. Importantly, as we see the favourable trends in increasing grades continuing at Pilar, we are optimistic that we will have a good second half of the year. We expect to meet our cost targets and production targets, as well as improved operating cash flows," concluded Mr. Guenther.
