Jaguar Mining Provides Q1 2009 Update of Operations

    Operations on Plan; Discovered Significant Mineralized Zone at Paciência

    JAG - TSX/NYSE Arca

    CONCORD, NH, April 14 /CNW/ - Jaguar Mining Inc. ("Jaguar" or "the
Company") (JAG: TSX/NYSE Arca, JAG.NT: TSX) provided a summary today of its
preliminary Q1 2009 operating performance. All figures are in U.S. dollars
unless otherwise indicated. See recent operating highlights below.

    Consolidated Operations (Turmalina, Paciência and Sabara)

    -   In Q1 2009, the Company produced 32,868 ounces of gold at an average
        cash operating cost of $409 per ounce compared to 21,414 ounces at an
        average cash operating cost of $428 per ounce during the same period
        last year, a production increase of 53%. Per plan, the Sabara
        operation was idled during Q1 2009, minimizing the seasonal effect.
        Sabara produced no gold during Q1 2009 compared to 4,259 ounces
        produced in Q1 2008. Leaching operations at Sabara resumed in
        April 2009.

    -   Q1 2009 gold sales rose to 35,879 ounces at an average price of
        $928 per ounce, 76% above the comparable Q1 2008 gold sales of
        20,344 ounces at an average price of $924 per ounce.

    -   Overall, Q1 2009 gold production was on target with the Company's
        2009 Plan. Cash operating costs were slightly higher (+3%) than
        planned but were offset by higher than expected selling prices (+9%).
        The Company's actual Q1 2009 cash operating margin of $519 per ounce
        exceeded the Company's expected cash operating margin of
        $455 per ounce.

    Turmalina Operations

    In Q1 2009, Turmalina produced 18,770 ounces of gold at an average cash
operating cost of $349 per ounce compared to 17,155 ounces at an average cash
operating cost of $387 per ounce in Q1 2008.

    The following was achieved at Turmalina during Q1 2009:

    -   Mine production totaled 128,861 tonnes of ore at an average
        run-of-mine ("ROM") grade of 5.47 grams per tonne.
    -   Ore processed through the mill totaled 120,173 tonnes at an average
        feed grade of 5.40 grams per tonne.
    -   The plant recovery rate averaged 90%.
    -   Mine development totaled 1.2 km.

    Work on the Phase I expansion at Turmalina continued on-schedule during
Q1 2009. Detailed engineering and the civil works for the expansion of the
carbon-in-pulp ("CIP") leaching circuit have been completed. Other components,
including steel fabrication, modifications to the grinding and milling
circuits and the tailings storage area are also underway. The expansion is
expected to be concluded during Q3 2009, increasing annual gold production by
25% from its present design of approximately 80,000 ounces to 100,000 ounces.

    Paciência Operations

    In Q1 2009, Paciência produced 14,099 ounces of gold at an average cash
operating cost of $490 per ounce compared to no production during Q1 2008.
Costs rose from $413 per ounce in Q4 2008 primarily due to (i) a decline in
the run-of-mine (ROM) grade from the St. Isabel Mine as new zones were brought
into production; (ii) the inclusion of ore from the Company's Pilar Mine where
freight charges are significantly higher than from the St. Isabel Mine; and
(iii) a slight decline in recovery rates to adjust the leach cycle time of the
Pilar Mine ore, which is blended with ore from the St. Isabel Mine.

    The following was achieved at Paciência during Q1 2009:

    -   Mine production from the St. Isabel Mine totaled 110,663 tonnes of
        ore at an average ROM grade of 2.86 grams per tonne and an additional
        38,673 tonnes at an average grade of 4.35 grams per tonne from the
        Pilar Mine.
    -   Ore processed through the mill totaled 154,737 tonnes with an average
        feed grade of 3.13 grams per tonne.
    -   The plant recovery rate averaged 91%.
    -   Mine development at the St. Isabel Mine totaled 0.8 km.

    Programs to improve mine output and grades at the St. Isabel Mine
continued to advance during Q1 2009. The current effort focuses on higher
grade lenses in the level 3 area of the mine which have not been accessed thus
far. As additional faces are opened, management believes a higher average
grade, in line with expectations, will be achieved during the remainder of

    Paciência: Material Disclosure of Potential New Discovery Zone

    As part of the development process at Paciência to extend an underground
drift from the NW01 portal to the second level of the St. Isabel Mine, a
significant mineralized zone was discovered during Q1 2009. The occurrence of
high grade ore shoots within the mineralized zones at Paciência has been a
well-known feature tracing back to the original surface mining conducted by
the Portuguese during the 17th and 18th centuries. Within the surface
excavation directly above the underground drift Jaguar is developing, a high
grade zone was cut with noticeable occurrences of visible gold. A drill hole
from surface into the zone below the drift produced a grade of 595 g/t over an
interval of 0.7 meters. Jaguar's exploration team conducted channel sampling
over a 10-meter span of the roof of the gallery in this mineralized zone with
the following selected results:

                   Sample number            Grams per tonne
                       585                            12.79
                       586                         1,781.00
                       587                           765.00
                       588                             7.03
                       589                            10.35
                       590                           887.00
                       591                           199.00
                       592                            44.67
                      1530                           284.00
                      1531                           251.00
                      1532                           245.00
                      1538                            21.50
                      1544                            25.00
                      1549                            48.75

    Of note, only 20 meters of drift development across this high-grade zone
has been completed of approximately 500 meters excavated on the surface by the
Portuguese. If the mineralization exhibits these ultra-high grades over the
remainder of the zone marked by the surface excavations, it is possible that
Jaguar could add significant new mineral resources to its resource base.
    There has not been sufficient exploration to define a mineral resource
based on these drill and channel sampling results and it is uncertain if
further exploration will result in mineral resources.
    Daniel Titcomb, Jaguar's President and CEO stated, "Our operations are
performing on plan. Turmalina operations are performing very well and the
expansion remains on-schedule. We believe the development program underway at
Paciência will increase the ROM grade during the St. Isabel Mine ramp-up,
significantly reducing our production costs to a level in-line with our 2009
plan. Although early in the process, the discovery of the ultra-high grade
zone at Paciência supports our long-standing belief of the mineralization
potential at this historic operation. Our exploration and underground
development programs continue to unearth additional low-cost resources that
are advancing our goal of becoming a mid-tier gold producer by 2011."

    Cash Position

    As previously disclosed, Jaguar raised net proceeds of approximately
$65.7 million through a public offering of common shares which closed on March
2, 2009. As of March 31, 2009 the Company held cash and cash equivalents of
approximately $87.8 million, including $3.1 million of restricted cash. Jaguar
intends that this capital, along with cash generated from operations will be
used to fund the build-out of the Caeté Project and expansions at existing
operations in an effort to reach its target of becoming a mid-tier gold
producer by 2011.
