FOR IMMEDIATE RELEASE
Jaguar Mining Turmalina Exploration Results Extend Orebody C Down Plunge and Laterally
Along Strike, Updates Infill Drilling
Toronto, February 27, 2019 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) today announced
drilling results from 19 holes over 4,523m as part of its growth exploration drill program on Orebody C, and
46 holes over 4,708m from infill drilling (39 holes at C-SE and 7 holes at C-Central) completed since June 2018
(Refer News Release February 26 and June 18, 2018) at Turmalina Gold Mine (“Turmalina”). The growth drilling
focused on targeting Orebody C extensions down plunge and laterally along str ike, and to upgrade mineral
resources to mineral reserves.
Turmalina Exploration Highlights
● Drill results c onfirm the structure hosting Orebody C extends to depth beyond mine level 8 ,500m down
plunge (400m vertically) from current operations and remains open at depth
● Drill results confirm changes in the plunge direction of the higher-grade ore shoot as mapped structurally in
mine development on levels 3 and 4 in Q3 2018
● 4 growth exploration holes intersected grade x thickness of > 10 GM including an intercept of 7.08 g/t Au
over 3.85m (ETW 3.2m)
● Completed infill drilling on Orebody C to upgrade and covert mineral resources to mineral reserves between
levels 3 and 5
● Key infill drilling intersections on Orebody C-SE include 5.76 g/t Au over 29.63m (ETW 22.69m), 6.40 g/t
Au over 14.80m (ETW 12.56m) and 5.65 g/t Au over 26.54m (ETW 19.09m)
● Infill drilling continued to define wide; high-grade intercepts in 19 intersections with a grade x th ickness of
> 10 GM including 15 intersections with grade x thickness > 25 GM, 5 intersections with grade x thickness
> 50 GM and 3 intersections with grade x thickness > 100 GM
● 8 infill holes targeting Orebody C-Central based on the new plunge interpretation include two higher grade
intersections from the drilling in this area completed to date of 18.35 g/t Au over 8.76m (ETW 8.23m) and
9.95g/t Au over 2.29m (ETW 2. 0m). Intersections appear to define a high -grade plunging mineralized
shoot, which extends over a strike length of approximately 50m
Definitions: ETW – estimated true width, g/t Au – grams per tonne gold, m – metres, Grade (g/t Au) x Thickness
(m) = GM (gram – meters)
Ben Guenther Interim CEO, Jaguar Mining commented: “We continue to improve our geological understanding
of Orebody C through structural mapping, targeted growth drilling and prioritized infill drilling. This stra tegic
approach enables us to plan and develop shallow mineralization that will provide Turmalina with additional ore
faces and operational flexibilit y. Development of C Central will also provide exploration platforms for
C NW and extend the orebody latera lly to increase longer term production capability. We look forward to
reporting our update Mineral Resources and Mineral Reserves during March 2019.”

Jon Hill, Expert Advisor, Geology and Exploration, Jaguar Mining Management Committee commented: “During
2018 exploration programs focused on upgrading mineral resource s to mineral reserves on both principle
orebodies at Turmalina. Concurrently, the Compan y has significantly advanced the understanding of the
structural and related geological controls on Orebody C mineralization through detailed geological mapping of
current and ongoing underground development. The recognition of a new plunge control to the distribution of
the higher grade and wider mineralized zones clearly broadens the potential to find additional higher -grade
mineralized “pay shoots” at shallower depths along the strike of the host structure and, more significantly, depth
extensions, down plunge from the C-Central and C-NW historically mined open pits.”
“The recent high-grade intercept on orebody C-Central with a grade x thickness value > 150 GM is encouraging
as we begin to evaluate previously under -tested areas assuming the newly identified plunge control. This work
is being prioritized as any increase in grade, tonnes and ounces per vertical meter added in shallow areas of
the mine may l everage access from existing infrastructure and provide more flexibility in the mine plan and
ultimately potential for higher production”.

Turmalina Orebody C Growth Exploration and Infill Drilling Results
Growth exploration drilling, targeting down dip extensions from level 4, continues to confirm the structure hosting
Orebody C extends to depth beyond mine level 8 approximately 500m down plunge and 400m vertically from
current operations. Importantly, this drilling successfully tested and confirmed the changes in the plunge
direction of the higher-grade ore shoot highlighted by earlier drilling and subsequently geologically – structurally
mapped in the mine development on levels 3 and 4 in Q3-2018 (Refer June 18, 2018 news release).
The new plunge direction assumed is N75/48 (azimuth / dip) (previous N45/55). This high-grade plunge direction
approximates the observed Orebody A high-grade zone plunge of N65/48.
Further drilling is planned for Q2 and Q3 2019 to fully test this ore-shoot between level 4 and level 8 once a new
drilling platform has been prepared for this purpose from the C-ramp on level 5. (Refer figure 2).
Infill drilling on Orebody C focusing on upgrading mineral resources to mineral reserves between levels 3 and 5
was prioritized in Q3 and Q4 to inform the Mineral Resources and Mineral Reserves update during March 2019.
This infill drilling continued to define wide; high-grade intercepts consistent with those previously reported (Refer
news releases dated June18, 2018 and February 26, 2018). In the results released today 19 intersections with
a grade x thickness of > 10 GM including 15 intersections with grade x thickness > 25 GM, 5 intersections with
grade x thickness > 50 GM and 3 intersections with grade x thickness > 100 GM. (Refer figure 3, table 2).
The observed change in the plunge control of the higher grade and wider parts of the Orebody Host Structure
has positive implications for interpreting and targeting additional shallow mineral ization further along the strike
of the Orebody C structure where clear potential exists for the identification and delineation of additional high
grade shoots below the C-Central and C-NW open pits.
Results are reported from 8 infill holes targeting Orebody C-Central along strike from Orebody C-SE (using the
mine drill rig) drilled as part of an ongoing drilling programme testing the potential for additional shallow,
structurally controlled “payshoots” associated with the new plunge interpretation. Two higher grade intersections
are reported from this drilling completed to date; 18.35 g/t Au over 8.76m (ETW 8.23m) and 9.95g/t Au over
2.29m (ETW 2.0m). These two holes define a high -grade plunging mineralized shoot, which extends over a
strike length currently estimated to be of the order of 50m in this area.
Further drilling and evaluation work targeting Orebodies C - Central and C -NW is in progress with the aim of
identifying and delineating mineable material close to existing development that is currently within 150m on
Orebody C-SE level 4. (Refer figure 4 and table 2).
Of Note, results and data from 18 infill drill holes out of the 46 infill drill hole results included in this report were
drilled after the database closed for the estimation at the end of 2018 Mineral Resources and Mineral Reserves.
The hole numbers and coordinate data for these 18 holes are included in Appendix 2.
