Jaguar Mining Reports Financial Results for the First Quarter 2021

Q1 2021 Financial Highlights

• Revenue for Q1 2021 increased 3% to $31.7 million, compared with $30.8 million in Q1 2020, due to a 20% increase in the average realized gold price of $1,793/oz in Q1 2021 as compared to $1,492/oz for Q1 2020. The increase in gold price was offset by 14% decrease of gold ounces sold of 17,677 ounces in Q1 2021 as compared to 20,640 for Q1 2020, mainly due to Covid-19 impacts on operations.
• Cash operating costs and All-in sustaining costs increased 20% and 17% to $835 and $1,296, respectively, per ounce of gold sold for Q1 2021, compared to $693 and $1,103 per ounce of gold sold for Q1 2020.
• Gross profit for Q1 2021 was $12.2 million, compared to $12.9 million for Q1 2020. The decrease in profitability reflects higher depreciation as well as slightly higher production costs.
• Net income for Q1 2021 decreased to $6.1 million, compared with $12.3 million in Q1 2020, mainly due to higher depreciation $1 million, increase in exploration expenditures $1 million, accounting write off on sale of CentroGold royalty $1.6 million and lower gain on foreign exchange $3.3 million.
• Free cash flow was $0.2 million for Q1 2021 based on operating cash flow, less capital expenditures, compared to $2.1 million in Q1 2020. Free cash flow was $11 per ounce sold in Q1 2021 compared to $101 per ounce sold in Q1 2020.
• Board announces quarterly dividend of C$0.08 per share to be paid on May 31, 2021.

Cash Position and Working Capital

• As of March 31, 2021, cash balance was $38 million compared to $39 million on December 31, 2020.

Q1 2021 Quarterly Dividend

• The Company is also pleased to announce that its Board of Directors has declared a cash dividend of C$0.08 per common share of the Company, to be paid on May 31, 2021 to shareholders of record as of the close of business on May 24, 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: "I am very pleased to have Jaguar entering Q2 in excellent financial health. Jaguar enters the second quarter of this year with a strong cash balance, increased working capital, and a commitment to build on the capital investment and exploration effort that were maintained in the past quarter. I believe that the commitment to invest in the future of Jaguar will lead to increasing resources and reserves to sustain our production levels and to grow through the utilization of unused capital capacity Jaguar has available."

Vern added, "The Company faced its greatest impact from Covid-19 in Q1 2021 as approximately 30% of our employees and contractors, the vast majority of which were in our operating division, spent some portion of time on leave as a result of either contracting the virus or in quarantine. This negatively impacted our overall financial and operating performance and metrics throughout the first quarter".

"The current wave of Covid-19 in Brazil appears to have passed its peak and is thankfully starting to recede in Q2 2021. We are seeing the same trends at our operations. I expect that production will ramp up to our sustainable levels of about 25,000 ounces per quarter as Covid-19 impacts continue to recede."

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.
