Jaguar Mining Reports Financial Results for the Second Quarter 2021

Announces Quarterly Dividend of C$0.04 per share

TORONTO, August 10, 2021 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG, OTCQX:JAGGF) today announced financial results for the second quarter ("Q2 2021") ended June 30. 2021. All figures are in US Dollars, unless otherwise expressed.

Q2 2021 Financial Highlights

• Revenue for Q2 2021 decreased 15% to $36.3 million, compared with $42.5 million in Q2 2020, mainly due to a reduction in gold sales by 19% to the comparison period, this was partially offset by 5% increase in the average realized gold price of $1,795/oz. in Q2 2021 as compared to $1,703/oz. for Q2 2020.
• Operating production costs of $17.4 million in Q2 2021 compared to $14.6M in Q2 2020. The increase in operating production cost is due to inflation and operational adjustments for the pandemic. The adjustments were based on the COVID-19 protocols put in place for the pandemic, as well as efforts to increase capacity as the mines worked to ramp production up to sustainable levels. Jaguar expects that easing of protocols in the second half of the year will allow operations to return to normal operating conditions.
• Cash operating costs increased 46% to $858 per ounce sold with the reduced ounces and increased costs, while All-in Sustaining Costs increased to $1,281 per ounce per ounce of sold for Q2 2021, compared to $586 and $882 respectively per ounce of gold sold for the same period in 2020. During the first half of the year 2021, the Company has seen significant inflation in labour costs, mining materials, plant consumables, diesel fuel, and explosives. These items have seen an increase on average of around 20% as compared to the same period last year. The Company believes that some of these increases will remain in place for the balance of the year.
• Net income for Q2 2021 decreased to $2.9 million, compared with $19.2 million in Q2 2020. Major differences were a $6.2 million decline in revenue, $1.6 million increase in depreciation expense, $1.2 million increase in exploration expenditures, and a foreign exchange loss of $3.3 million. The average exchange rate during Q2 2021 was R$5.29 per US dollar compared to R$5.39 per US dollar in Q2 2020.
• Free cash flow was $5.8 million for Q2 2021 based on operating cash flow minus capital expenditures, compared to $21.4 million in Q2 2020. Free cash flow was $285 per ounce sold in Q2 2021 compared to $858 per ounce sold in Q2 2020.

Q2 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 August 30, 2021, to shareholders of record as of the close of business on August 23, 2021. 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.
• Given the impact on the business due to Covid-19, the board has determined that a reduction in the dividend in favor of additional investment in our primary development and growth and exploration pipeline is the most optimal use of Jaguar's cashflow.

Cash Position and Working Capital

• As of June 30, 2021, a cash balance of $34.4 million compared to $37.8 million on March 31, 2021.
• As of June 30, 2021, working capital was $29.9 million, compared to $29 million on December 31, 2020, which includes $3 million in short term loans from Brazilian banks.

Vern Baker, President and CEO of Jaguar Mining stated: "Jaguar began moving back toward our sustainable production levels in the second half of Q2 2021. Production of over 20,000 ounces was the first step in bringing ounce production back to sustainable levels. Within the limitations of the first half of the year the company managed to expand the exploration program and increase capital expenditures on growth projects. Jaguar sees significant potential for growth and will increase expenditures on exploration and growth in the second half of the year."

Vern added, "Similarly to Brazil, Jaguar was impacted by Covid-19 in Q1 2021 and Q2 2021. Jaguar has seen the impacts of the pandemic reducing in the second half of Q2 2021 and expects operations to return to normal in the next few months. Jaguar is working to ensure our work force receives the Covid-19 vaccination and expects our workforce to be near full vaccination levels later this year. One of the impacts from the pandemic appears to be inflation. Our operations are seeing that our main inputs of steel, chemicals, and diesel are all experiencing significant upward price pressure. Jaguar has committed to several focused projects to minimize the effect of inflation on our costs. Efforts to reduce consumption, push back price hikes, and improve productivity should begin to impact costs in the next several quarters.

"The challenges at this point for Jaguar are to bring ounce production levels up to target, keep costs down, and to begin capitalizing on the exploration results we are seeing. The Jaguar team is focused on accomplishing these challenges over the next two quarters."

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).

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 expands 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 June 30. 2021, is set out in the Company's second quarter 2020 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 June 30. 2021, is set out in the Company's second quarter 2021 MD&A filed on SEDAR at www.sedar.com.
