Turmalina Delivers Further High-Grade Intercepts from In-Mine, Exploration and Resource

Conversion Drilling

Drilling highlights include:

22.87 g/t Au over an estimated true width of 5.4m in Orebody CNW

13.54 g/t Au over an estimated true width of 6.4m in Orebody B

7.98 g/t Au over 5.2m* in Pontal South

9.51 g/t Au over 9.8m*in Faina Resource Conversion Infill Drilling

Toronto, February 14, 2023 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG, OTCQX: JAGGF)

is pleased to announce positive results from ongoing exploration and growth activities at its Turmalina Complex

located in Minas Gerais, Brazil.

In the fourth quarter of 2022, t he Company progressed several priority diamond drill campaigns focused on high

grade extensions of mineralization discovered earlier in 2022. The most recent exploration diamond drilling focused

on high grade mineralization in the C Structure at Turmalina, follow-up step-out drilling at its Pontal South Discovery

(press release dated September 6, 2022), and high-grade targets within the B Structure (press release dated June

04, 2019) also at shallow levels in the mine.

Results from the drilling have been encouraging with continued high grade s over mineable widths reported from

various areas within the C and B Mineralized Structure s including the identification of a new mineralized structure

in the footwall of the C Structure.

Step out drilling at the Pontal South Discovery has demonstrated continuity of high -grade mineralization to depth

down plunge.

At the Faina Growth Project, t he Company completed approximately 15 ,359 meters (46 holes) of infill resource

conversion drilling with the goal of converting the published Inferred Mineral Resource to an Indicated Mineral

Resource. Infill drilling at Faina has confirmed the high-grade characteristics of this mineralization and continuity

within the deposit. This drilling underpins the geological and grade model for this important growth project.

The Company will publish updated Mineral Reserves and Mineral Resources with its AIF in March 2023.

* (Drilled widths – true width unknown))

Vern Baker CEO Jaguar commented “I am very excited about the positive drill results reported today as they support

the Company’s organic growth plans and ultimately our future production profile. The high grades in the C and B

Structures are at shallow levels and close to development in the se sectors of the mine which justifies our plan to

focus production in th ese areas and support ongoing underground access development towards the Faina

Resource. The success of infill drilling at Faina and the continued definition of new mineralized areas along the

main structural trend continue to demonstrate the upside potential of this trend”.

Turmalina Mine – Orebody C and B Structure Drilling

At Turmalina, drilling in the later part of 2022 and into 2023 focused on further delineation and expansion of higher-

grade mineralization manifested within the C Structure at shallow depths and close to current mining access and

production development Step out drill testing the projected plunge continuity is su ccessfully expanding the higher-

grade footprint in a series of structurally controlled zones. Similarly, exploratory work aimed at refining the

geological-structural controls on higher grade mineralization within the B Structure, has recently recommenced, also

at shallow levels close to existing underground mine development access. ( Press releases dated September 6,

2022 and June 4, 2019).

Of note is the intersection of a newly identified structure in the footwall to the known mineralized zones within the C

Structure. Hole FTS2165 intersected a mineralized interval grading 3.88 g/t Au over an estimated true thickness of

6.6m.

High grade mineralization intercepts with grade x thickness (GT) > 25 (gram per tonne meter) are tabulated below.

Pontal South - Follow Up Step Out Drilling

In September 2022, the Company announced the discovery of mineralization at Pontal South located in the gap

between the previously identified Mineral Resources at Pontal and Faina within the overall main Turmalina structural

trend.

Subsequent step out drilling confirmed continuity of the mineralization to depth down plunge with a high grade

intersection in hole PTL 105 which reported 4.69 g/t Au over a drilled width of 10.1m including 7.98 g/t Au over a

drilled width of 5.2m .

Faina Growth Project Resource Conversion Drilling

At Faina, 15,359 meters of infill drilling (46 Holes) completed in 2022 aimed at converting the published Inferred

Mineral Resource Inventory (M+I+I Resource 417Koz @ 7.2 g/t Au) to Indicated Mineral Resource Inventory.

Infill drilling at Faina largely confirmed the continuity and high -grade characteristics of this deposit which has

informed a full update of the geological and grade model to support the planned progression of this project through

the PEA and PFS processes.

The Company will publish updated Mineral Reserves and Mineral Resources along with its AIF in March 2023.
