Jaguar Mining Reports Financial Results for the Third Quarter 2021

TORONTO, November 8, 2021 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) today announced financial results for the Third quarter ("Q3 2021") ended September 30, 2021. All figures are in US Dollars, unless otherwise expressed.

Q3 2021 Financial Highlights

• Revenue for Q3 2021 decreased 6% to $40.7 million, compared with $43.5 million in Q3 2020, mainly due to a reduction in the average realized gold price of $1,753/oz. in Q3 2021 as compared to $1,896/oz. for Q3 2020.
• Operating production costs of $19.4 million in Q3 2021 as compared to $14.1M in Q3 2020. The increase in operating cost is primarily due to local inflationary pressure on wages, mining materials and plant consumables, higher tonnes processed and higher secondary development.
• Cash operating costs increased 36% to $833 per ounce of gold sold as a result of reduced ounces sold and increased production costs, while All-in Sustaining Costs increased to $1,184 per ounce of gold sold for Q3 2021, compared to $614 and $1,011 respectively per ounce of gold sold for the same period in 2020.
• Net income for Q3 2021 decreased to $11.4 million, compared with $16.5 million in Q3 2020. Major differences were a $2.7 million decline in revenue, $5.3 million increase in operating cost due to production costs increasing, and a $1.9 million increase in depreciation, offset by a foreign exchange gain of $1.9 million, income tax expense reduction of $2 million, and a decrease of $0.9 million in operating expenses.
• Free cash flow was $9.8 million for Q3 2021 based on operating cash flow minus capital expenditures, compared to $14.9 million in Q3 2020. Free cash flow was $423 per ounce sold in Q3 2021 compared to $651 per ounce sold in Q3 2020.

Cash Position and Working Capital

• As of September 30, 2021, with cash of $38.1 million compared to $34.4 million on June 30, 2021.
• As of September 30, 2021, working capital was $33 million, compared to $29 million as at December 31, 2020, which includes $3 million in short term loans from Brazilian banks.
• A $3.7M net increase in cash represents (i) $16.4M in cash generated from operating activities, offset by (ii) $10.4M used in investing activities, and (iii) $2.3M cash used in financing activities for dividend payment.

Q3 2021 Quarterly Dividend

• The Company is also pleased to announce that its Board of Directors has declared a cash dividend of C$0.04 per common share of the Company, to be paid on November 30, 2021, to shareholders of record as of the close of business on November 23, 2021. This is the same amount as paid in the previous three quarters. The dividend qualifies as an eligible dividend for Canadian income tax purposes.
• The Board of Directors intends to review, among other things, the Company's budget, cash flow forecast and existing market conditions on a quarterly basis in order to determine whether any additional dividends will be declared on Shares for subsequent quarters.

Vern Baker, President and CEO of Jaguar Mining stated: "Jaguar completed the third quarter with a strong balance sheet, positive cash flow from both operations, an exploration effort developing new resources both within and outside our current operations, and with the queueing up of several projects with the potential to contribute over the next few years.

The disappointing aspect of our quarter was the increase in operating expenses. The main contributing factors to our cost increase were inflation across all components of operating expenditures, an increase of 15% in tonnes mined and milled, and the additional measures for health monitoring, hygiene and distancing made during the pandemic. Inflation is clearly something we will be dealing with for the remainder of this year and into next year. Now that we believe the bulk of the pandemic issues are behind us, Jaguar is working on several initiatives to reduce costs to begin countering inflation and we are looking to begin removing the additional measures taken to combat the pandemic.

In 2021 lower head grades have been the key contributor to a weaker AISC per ounce. Efforts to improve the grade of the ore going into our mills began paying off in Q3 as we experienced our best overall grade of the year. Turmalina experienced its best head grade quarter in the last 4 quarters and sees improving statistics on all quality measures. Pilar´s head grade remained consistent with the reserve grade, and we foresee improvement on quality statistics (dilution, recovery, model reconciliation) as the mine continues on a sustainable path.

In Q3 2021 the Jaguar team was able to push all our exploration and growth project work, sustainably develop our mines, pay a dividend, and maintain a strong balance sheet. We are confident we can continue in this manner and utilize our infrastructure and exploration properties to organically grow our production base."
