• Consolidated Cash operating costs ("COC") increased 7% to $795 per ounce

• Gross profit increased 56.3% to $21.1 million reflecting a 21% decrease in operating expenses year-over-year
• COC of $732 per ounce, 13% improvement over $837 per ounce for FY 2017
• AISC of $1,244 per ounce, 3% increase over $1,212 for FY 2017 due to lower than anticipated gold production
• Operating cash flow increased 42% to $21.2 million; adjusted EBITDA decreased 4.6% to $20.7 million
• Net loss of $16.0 million compared to a net loss of $2.8 million in 2017 (includes an impairment charge of $9.0 million)

"Our top priority is executing the turnaround plan at Turmalina to increase production. During the fourth quarter several execution challenges resulted in lower than expected production," said Ben Guenther, Interim CEO, Jaguar Mining. "Despite this performance, we delivered record annual production at Pilar and added new Turmalina operations management."

"In terms of exploration, 2018 was an outstanding year that saw investment in infill and growth drilling, focused on converting mineral resources resulting in an 81% increase in proven and probable reserves."


Q4 2018 Financial Results

• Cash balance of approximately $6.3 million as of December 30, 2018, compared to a cash balance of $6.7 million at September 30, 2018, and $18.6 million as at December 31, 2017. 2018 year-end cash balance excludes a $2 million cash deposit held with Auramet and $0.5 million margin deposit with Banco Votorantim.
• Lower year-over-year cash balance reflects $30.5 million invested in capital expenditures, of which $28 million was invested in sustaining CAPEX activities including significant development at Turmalina and Pilar Gold mines. Also, lower gold production contributed to the lower cash balance at the end of 2018. In 2018, the company generated approximately $21.2 million in operating cash flow. In addition, $5.2 million was paid in financing activities.

Secured Bridge Facility

• Company completed a short-term senior secured bridge facility (the "Facility") with Auramet International LLC ("Auramet") for US$7.85 million at 14%, with a term of 120 days expiring on July 15, 2019.
• The facility is secured by all shares of Jaguar's 100% owned subsidiary Mineracao Serras Do Oeste Eireli (MSOL).
• Net proceeds are intended to fund working capital requirements, underground development at Turmalina and general corporate purposes.
• The Company continues to explore longer term financing options that may include the issuance of debt or convertible debt securities, the issuance of various forms of equity securities, joint venture or other arrangements with third parties, or the sale of certain assets. There is no assurance that any such financing transaction will be completed within the 120-day term of the Facility.

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699–1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with just over 25,000 hectares.

Non-IFRS Measures

This news release provides certain financial measures that do not have a standardized meaning prescribed by IFRS. Readers are cautioned to review the below stated footnotes where the Company expanded on its use of non-IFRS measures.

1. Cash operating costs and cash operating cost per ounce are non-IFRS measures. In the gold mining industry, cash operating costs and cash operating costs per ounce are common performance measures but do not have any standardized meaning. Cash operating costs are derived from amounts included in the Consolidated Statements of Comprehensive Income (Loss) and include mine-site operating costs such as mining, processing and administration, as well as royalty expenses, but exclude depreciation, depletion, share-based payment expenses, and reclamation costs. Cash operating costs per ounce are based on ounces produced and are calculated by dividing cash operating costs by commercial gold ounces produced; US$ cash operating costs per ounce produced are derived from the cash operating costs per ounce produced translated using the average Brazilian Central Bank R$/US$ exchange rate. The Company discloses cash operating costs and cash operating costs per ounce, as it believes those measures provide valuable assistance to investors and analysts in evaluating the Company's operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with IFRS is total production costs. A reconciliation of cash operating costs per ounce to total production costs for the most recent reporting period, the quarter ended December 31, 2018, is set out in the Company's fourth quarter 2018 Management Discussion and Analysis (MD&A) filed on SEDAR at www.sedar.com.
   
   
2. All-in sustaining cost is a non-IFRS measure. This measure is intended to assist readers in evaluating the total costs of producing gold from current operations. While there is no standardized meaning across the industry for this measure, except for non-cash items the Company's definition conforms to the all-in sustaining cost definition as set out by the World Gold Council in its guidance note dated June 27, 2013. The Company defines all-in sustaining cost as the sum of production costs, sustaining capital (capital required to maintain current operations at existing levels), corporate general and administrative expenses, and in-mine exploration expenses. All-in sustaining cost excludes growth capital, reclamation cost accretion related to current operations, interest and other financing costs, and taxes. A reconciliation of all-in sustaining cost to total production costs for the most recent reporting period, the quarter ended December 31, 2018, is set out in the Company's fourth quarter 2018 MD&A filed on SEDAR at www.sedar.com.
