JAGUAR MINING PROVIDES POSITIVE RESULTS FROM ITS 2023 EXPLORATION PROGRAM

HIGHLIGHTS INCLUDE:

High-grade diamond drilling intercept of 16.69 g/t Au over a true width of 4.8m at Carrancas

High-grade trench (up to 8.89 g/t Au over 10.4m) and outcrop rock-chip sampling program (up to

21.9 g/t Au) defines 3km mineralized strike along the Rio do Peixe trend close to the Paciência

Complex

Strong (>100ppb Au) gold in-soil anomaly extends mineralization trend 4km southwards at

Paciência Complex.

Toronto, March 4, 2024 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG; OTCQX: JAGGF)

is pleased to announce positive results from exploration activities completed during 2023 over three new target

trends across the Company’s extensive tenement portfolio, located in the Iron Quadrangle in the state of Minas

Gerais, Brazil.

During 2023, in parallel with its in -mine exploration activities, the Company continued to advance generative

and phase-one exploration programs over areas identified as high priority targets. These targets are strategically

important as they are the pipeline of high potential exploration projects in Jaguar’s extensive tenement package.

The package, which is 56,000 Ha includes tenements attributed to its 2023 acquisition of IAMGOLD’s Brazilian

assets.

The majority of work completed focused on initial reconnaissance drill testing of the Carancas target within the

Rocinha – Carrancas – Carneiro trend close to the Company’s Caeté complex. Outcrop and trench sampling at

various targets along the Rio do Peixe trend and soil sampling targeting previously untested southern extensions

to the mineralized Paciência trend from the currently closed Santa Isabel mine southwards to the tenement limit.

Jon Hill, VP Exploration and Geology at Jaguar Mining stated: “Exploring a pipeline of high potential targets

within our exploration portfolio is a fundamental part of the Company´s long term strategy. This past year was a

breakthrough year for us as we reported initial Mineral Reserves at our Faina project, reported a material

increase in Mineral Resource inventories booked through the acquisition of IAMGOLD’s Brazilian assets, and

advanced a new high grade mineralized zone on the BA structure at our Pilar mine. Our ability to continually

generate and progress high quality priority targets across our 56 ,000 Ha strategic tenement package again

speaks to the quality of our portfolio and the opportunity the Company has for new discoveries.”

Rocinha – Carrancas – Carneiro trend

This mineralized trend is 9km to the east of the Company´s Caeté plant and is defined by extensive historical

surface and underground excavations which have been mapped and sampled over approximately 5km of strike

length. Rock chip channel sampling of historical underground excavations reported several very high-grade

samples over intervals ranging from 0.7m to over 3m in true thickness . The mineralization is associated with

silicification and quartz veining and quartz -sericite-chlorite-carbonate alteration with associated fine

disseminated pyrite within a series of shallow-dipping shear zones which traverse the host greenschist sequence

at a shallow angle . The host greenschists comprise both metavolcanic and metasedimentary units and

interlayered banded iron formation. Rock chip channel samples collected from the underground excavations

with grade x thickness (GT) >10 are tabulated below in Table 1.

Table 1. Rock chip channel samples collected from the underground excavations with grade x thickness

(GT) > 10 (ETW = Estimated True Width; GT=grade x thickness).

The Company completed a series of shallow reconnaissance diamond drill holes in 2023 to confirm the

orientation and quantify the upside potential of the high-grade mineralization sampled in the underground

workings. The first hole, FCAR001 intersected a wide zone of mineralization grading 16.69 g/t Au over a true

width of 4.8m, which significantly enhanced the p otential of this project (Table 2). The targeted structure was

successfully intersected in several step-out holes but reported lower grades and thicknesses (Appendix 1).

Based on this early work, the geological models are being reviewed and refined to determine what geological

conditions can be used distinguish more favourable sites for higher grade, thicker areas from lower grade

narrower areas to inform drill targeting going forward.

Rio do Peixe Trend

This Rio do Peixe mineralized trend is located approximately 20km north-east of the Company´s Paci ência

complex and is defined by extensive historical surface and underground excavations which have been mapped

and sampled by the Company over 3km of strike. Surface trenching and rock chip sampling have returned

encouraging sampling results which include a best trench sample result of 8.89 g/t Au over 10.4m (true width

unknown) and rock chip samples up to 21.9 g/t Au.

The mineralization is associated with quartz veining and quartz -sericite-chlorite-carbonate alteration with fine

disseminated pyrite within a series of steep-dipping mylonitic shear zones. The host greenschists comprise

variably sheared ultramafic, mafic and quartz - sericite schists and banded iron formation.

Paciência Trend

The Paci ência trend is defined by a major mineralized crustal shear zone which traverses the Company’s

Paciência complex tenement package over a strike length of so me 15km. In 2023, the Company completed a

soil sampling program (1,200 samples) targeting previously untested southern extensions to the mineralized

Paciência trend from the currently closed Santa Isabel mine southwards to the tenement limit.

This program has successfully defined a robust (>100ppb Au), gold in-soil anomaly named Chamé – Cedro that

extends the potential mineralization trend southwards along this structure by 4km. Follow-up surface mapping

and rock chip sampling has reported to date, more the 10 samples with gold values greater than 5 g/t Au with a

peak grade of 22 g/t Au.

Quality Control

All sampling and samples utilized at Jaguar uses a quality-control program that includes insertion of blanks and

commercial standards in order to ensure best practice in sampling and analysis.

HQ, NQ, and BQ size drill core is sawn in half with a diamond saw. Samples are selected for analysis in standard

intervals according to geological characteristics such as lithology and hydrothermal alteration. Rock channel

sampling of the underground development follows the same standard intervals as for the drill core.

Half of the sawed sample is forwarded to the analytical laboratory for analysis while the remaining half of the

core is stored in a secure location. The drill core and rock chip samples for resource -reserve conversion and

grade control samples are transpor ted for physical preparation and analysis in securely sealed bags to the

Company’s in-house laboratory located at the Caeté complex, in Caeté, Minas Gerais. Growth exploration

samples are sent to the independent ALS Brazil (subsidiary of ALS Global) laboratory located in Vespasiano,

Minas Gerais, Brazil. The analysis of these exploration samples is conducted at ALS Global’s respective facilities

(fire assay is conducted by ALS Global in Lima, Peru, and multi-elementary analysis is conducted by ALS Global

in Vancouver, Canada). ALS has accreditation in a global management system that meets all requirements of

international standards ISO/IEC 17025:2005 and ISO 9001:2015. All major ALS geochemistry analytical

laboratories are accredited to ISO/IEC 17025:2005 for specific analytical procedures.

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.
