Toronto, Canada, April 27, 2015 - Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX-V) today announced multiple high-grade drill intercepts, in particular drill hole PPL302 which intercepted 18.22 grams per tonne gold over 7.4 meters, generated from underground exploration drilling at its 100% owned Pilar Mine located in Minas Gerais, Brazil.

The Pilar Mine is one of two underground mines that provide ore to the Caete Complex ("Caete") and represents approximately two-thirds of the ounces produced at Caete.

The drilling program, initially launched in Q3 2014, is largely focused to test potential depth extensions of mineralization below the current mine working levels.

All newly reported holes in Table 1 have intersected high-grade mineralization confirming the extension of a mineralized system in depth at the Pilar mine. Additionally, the high-grade mineralization was identified at the footwall of the main AB ore body (picture 1) providing an opportunity to add new resources in depth extension at the Pilar Mine.

George Bee, Chief Executive Officer of Jaguar commented: "These drill hole intercepts confirm the potential of expanding reserves and resources at the Pilar Mine, thereby potentially expanding the existing life-of-mine and production profile. With these results, we have re-initiated mine planning activities in order to consider a restart of primary and secondary development activities at Caeté, however, any decision to restart development activities will be deferred until the current exploration program is concluded, mine planning/costing has been completed and positive economic results from a restart of development are evident."

Drill hole PPL160 intercepted 14.04 grams per tonne Au ("g/t Gold") over 8.7 meters, drill hole PPL294 intercepted 10.63 grams per tonne Au over 13.6 meters, drill hole PPL304 intercepted 20.98 grams per tonne Au over 3.7 meters and drill hole PPL307 intercepted 18.22 grams per tonne Au over 7.4 meters, including 27.19 grams per tonne Au over 4.3 meters. Table 1 below contains intersections in AB ore body drilled between September 2014 and April 2015.

Intersections do not represent true thickness and have been drilled from drill platforms in the hanging wall aiming to intersect the mineral resource as perpendicular to the plunge and dip of the projected mineralization as possible.

This drilling program also includes representative intercepts at ore body C (picture 2), confirming previous results of nearby drill holes. These results increase geological information, providing the opportunity to convert mineral resources to a higher confidence classification in these specific areas.

Drill hole FSB502 intercepted 41.99 grams per tonne Au ("g/t Gold") over 4.3 meters, including 128.33 grams per tonne Au over 1 meter, drill hole FSB499 intercepted 12.23 grams per tonne Au over 6.3 meters and drill hole FSB501 intercepted 10.95 grams per tonne Au over 6.6 meters, including 24.86 grams per tonne over 1.3 meters.

Quality Control
Jaguar Mining has implemented a quality-control program that includes insertion of blanks, commercial standards and duplicate core samples in order to ensure best practice in sampling and analysis. NQ and BQ size drill core is saw cut and half the drill core is sampled in standard intervals according to geological characteristics such as lithology and hydrothermal alteration contents. The remaining half of the core is stored in a secure location. Rock channel sampling of the underground development follows the same standard intervals of the drill core. The drill core samples are transported in security sealed bags to the in-house Roça Grande Mine Laboratory, Caeté, Minas Gerais and occasionally to the independent SGS Geosol laboratory in Vespasiano, Minas Gerais. The rock chip samples are transported in security sealed bags to the Roça Grande Mine Laboratory, Caeté, Minas Gerais. The preparation and analysis are all conducted at the respective facilities, either at the Roça Grande Mine Laboratory in Caeté, MG or at the SGS Geosol Laboratory in Vespasiano, MG. The Roça Grande Mine Laboratory does not carry an ISO certification. The SGS Geosol Laboratory is ISO 9001 accredited. As part of in-house QA/QC the Roça Grande Mine Laboratory inserts certified gold standards, blanks and pulp duplicate samples.
