Consolidated Production up 11% to 20,212 Ounces

Recovery Continues to Sustainable Levels Across all Operations

Company Maintains Strong Balance Sheet & Liquidity

TORONTO, ON / ACCESSWIRE / July 13, 2021 / Jaguar Mining Inc. ('Jaguar' or the 'Company') (TSX:JAG)(OTCQX:JAGGF) today announced interim gold production results for the Second quarter of 2021 ('Q2 2021'). Financial results for Q2 2021 will be reported and filed on SEDAR on or before August 15, 2021. All figures are in US Dollars, unless otherwise expressed.

Vern Baker, President and CEO of Jaguar Mining stated: 'I am very pleased to announce that our team has delivered over 20,000 production ounces for the second quarter. Consolidated production increased 11% over Q1 (from 18,161 to 20,212 ounces) and development metres increased by 19% over Q1 (from 2,017m to 2,400m). This was accomplished in a quarter that started out with Brazil and therefore Jaguar, experiencing peak impacts of the COVID-19 pandemic. By mid-May, Brazil was experiencing a notable reduction in pandemic infection rates and the impact to Jaguar's operations also decreased significantly. Although the company continues to be impacted by some cases, the number is now manageable, and the team continues to work with adjusted operating practices. I am pleased to report that the number of cases impacting the operations in the first week of the current third quarter is at a much lower level and expect that we will see a shift towards pre-pandemic operations in the second half of the year. Vaccination roll outs across the state of Minas Gerais and throughout Brazil are proceeding well and although we will continue to see some cases of infection within the workforce, we anticipate they will be at manageable levels. Jaguar expects that by the end of the third quarter, most of the workforce should be vaccinated. While the pandemic and its affects are unpredictable, currently, I fully expect to see continuing recovery of production levels in the next two quarters as our teams work to achieve sustainable levels at both mines.

I am very pleased with the performance at Pilar and the changes made to ensure a strong second half of the year. Our mining team increased production to 4,000 ounces a month for May and June. Quarterly production for Q2 was up 20% from Q1 (from 9,643 ounces to 11,627 ounces) at the mine, along with an increase of 12% in development metres from Q1 to Q2 (from 888 to 997). Pilar processed good tonnage, averaging 38,000 tonnes per month and the grade was close to reserve levels. Pilar expects to perform at sustainable levels for the remainder of the year.

Turmalina has been experiencing a slower return to sustainable levels of production, but I expect to see improvement in the second half of the year. Production for Q2 at Turmalina was 8,577 ounces, consistent with Q1 and development rates picked up by 24% in Q2 from Q1 (from 1,128m to 1,403m). While tonnage has been reasonable, it has depended on a large component of those tonnes coming from shallower areas of the mine. As those areas are of lower grade, the mine´s ROM grades have been lower than the reserve. Dilution has also impacted grades as limited availability of skilled operators during the pandemic cut short the drilling capacity available for cablebolting. The current challenge at the mine is to deliver reserve grade production tonnes to the mill. I am confident the team at Turmalina is focused on making the changes needed to return to reserve grades in the current year.

During the height of the pandemic, in the first half of the second quarter, we put our exploration/third party drillers on stand-by to reduce the number of people stationed in our local communities (done at the request of community leadership). By June we were back to full crews drilling on both surface properties and in our underground mines.

While the first half of the year has been disappointing in terms of production, it has also provided us with opportunities in the form of data and perspective for starting key projects within or near the mines in the second half of the year. One such project, is the accelerated development of the SW ore system in the Pilar Mine. This will provide additional mining areas from level 9 and up to provide additional capacity and flexibility in production. At Turmalina the team is working on a project to develop the northwest trend of the CNW ore body at shallow levels beginning on level 1. The team is also evaluating a narrow vein project at Turmalina which can allow us to take advantage of narrow, good grade zones left as remnants located higher up in the mine. And, from exploration results the engineering team is initiating a pre-feasibility study on the Faina resource to add mining capacity at Turmalina.'

Q2 2021 Operating Highlights

• Consolidated gold production decreased 14% with 20,204 ounces compared to 23,483 ounces produced in Q2 2020. Grade also decreased to 3.29 g/t compared to 4.00 g/t in Q2 2020.
• Pilar production decreased 14% with 11,627 ounces compared to 13,452 ounces produced in Q2 2020.
• Turmalina production decreased 14% with 8,577 ounces, compared to 10,031 ounces produced in Q2 2020.
• Total development of 2,400 metres for the second quarter of 2021 was in line compared to the same period in 2020 with 2,445 metres.
• Total definition, infill and exploration drilling decreased 17% to 11,870 metres compared to 14,278 metres drilled in Q2 2020.
  • Drilling limited due to the pandemic for the first half of the quarter,
  • Growth in resources and reserves from drilling is expected to be completed this year.
• Treasury position as of June 30, 2021, with cash of $34.7 million compared to cash of $37.8 million on March 31, 2021. During the quarter, the Company paid a dividend of $4.8 million.

The table below summarizes Q2 2021 operating results compared to Q2 2020:

Vern continued; 'Our commitment to exploration in the Iron Quadrangle continues with several on-going exploration programs including a focus on growing mineral resources and reserves in and around the mines. I believe our team can develop an expanded resource base that will allow us to grow production at each mine. We also have several programs on properties adjacent to, or nearby, our processing plants. These include Zona Basal near Turmalina where we are planning a significant reverse circulation drilling program in the second half of the year. The exploration team is following up on some excellent results on the Corrego Brandão prospect near our Caeté plant which also feeds the Pilar Mine. And we have a full team working on the Acurui project which is part of our JV with IAMGOLD and is located near the Paciência plant.

With the solid recovery that continues in production, our development projects and our exploration portfolio, which is starting to deliver excellent results, I look forward to reporting on a much improved second half of the year to our shareholders.'

Risks and Mitigating Factors
Jaguar is maintaining its social licenses to operate in all sites throughout Brazil and continues to deliver on its ethical and collaborative partnerships with employees, suppliers, local communities and unions. During this COVID-19 pandemic, the Company has formulated a formal COVID-19 Action Plan which has been adopted company-wide. The Action Plan is committed to sustainability while implementing increased health and safety initiatives with all stakeholders, emphasizing the protection of employees and their employment.

COVID-19 remains the largest question mark for all companies. At any time, state and federal government mandates may change and any mandate that would result in the shutdown of operations will affect the Company's production. As well, the pandemic may impact the availability of our workforce or supplies. Jaguar is not able to predict the consequences of the pandemic over the next several months and hence is unable to project the impact on production at the current time.

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 37,000 hectares.
