Jaguar Mining Provides Q1 2010 Update of Operations

JAG - TSX/NYSE

CONCORD, NH, April 15 /CNW/ - Jaguar Mining Inc. ("Jaguar" or "the Company") (JAG: TSX/NYSE) provided a summary today of its preliminary Q1 2010 operating performance. All figures are in U.S. dollars unless otherwise indicated. See recent operating highlights below.

    
    Consolidated Operations (Turmalina and Paciência)

    -   In Q1 2010, the Company produced 31,223 ounces of gold at an average
        cash operating cost of $595 per ounce compared to 32,868 ounces at an
        average cash operating cost of $409 per ounce during the same period
        last year, a production decrease of 5%. Beginning in Q1 2010, the
        Company adopted a definition of "to the refinery" for measuring gold
        production. As a result of this change, the Q1 2010 production figure
        does not include gold in-process or in unfinished inventory as was
        the case for quarterly production data prior to Q1 2010.

        Q1 2010 cash operating costs were significantly impacted by a much
        stronger Brazilian real in early-2010 compared to the previous year.
        The exchange rate in Q1 2010 averaged R$1.80 per $1.00 compared to R
        $2.32 per $1.00 in Q1 2009 or approximately 30% higher, which caused
        an increase in cash operating costs of approximately $120 per ounce.

        In addition, cash operating costs and production were slightly
        impacted by lower grades at Turmalina and downtime related to
        scheduled maintenance at both Turmalina and Paciência. As a result of
        lower production, the allocation of fixed costs related to operations
        also contributed to the increase of costs per ounce during Q1.

    -   The Q1 2010 average feed grade was 3.74 g/t compared to 4.19 g/t
        during Q1 2009. Feed grades have been improving slightly since Q4
        2009 and are expected to continue to improve based on the detailed
        2010 mine plan. Feed grades for the remainder of 2010 are expected to
        average between 3.8 g/t to 4.1 g/t, which includes lower grades into
        the Caeté Plant during the commissioning phase.

    -   Q1 2010 gold sales totaled 37,289 ounces at an average price of
        $1,102 compared to 35,879 ounces at an average price of $928 per
        ounce in Q1 2009.

    -   Q1 2010 gold production and cash operating costs were generally on
        target with the Company's 2010 plan. Q1 was expected to have the
        year's lowest production and grade and the highest cash operating
        costs. The Company's actual Q1 2010 cash operating margin of $507 per
        ounce exceeded the Company's expected cash operating margin of $412
        per ounce.

    -   Consolidated underground mine development for Q1 2010 totaled 4.5 km,
        considerably above Q1 2009's level of 2.3 km.
    

Mr. Daniel R. Titcomb, Jaguar's President and CEO stated, "Our Q1 results were roughly in-line with our expectations as we worked around major scheduled maintenance items and sequencing issues underground which delayed short-term access to higher-grade zones. What isn't fully revealed in the Q1 results is the progress we made during Q1 underground to access these higher-grade zones, particularly at Turmalina and at the new Palmital Mine in the Paciência region, which makes us confident we will reach this year's production and cash operating cost targets."

Mr. Titcomb further stated, "Recently our operating team successfully tested Turmalina's milling rate at more than 25% above our 2007 plan of 700,000 tonnes per year; a very positive development which is important to achieving our 2011 and beyond production targets. Tests conducted on ore samples from the Paciência ore zones produced very favorable results with respect to implementing new roller press technologies, which could significantly reduce capital expenditures tied to growth plans for the Paciência Operation. Jaguar believes that the foundation for achieving our growth plans will be in-place shortly as the Caeté Plant is nearing completion."

Turmalina Operations

In Q1 2010, Turmalina produced 16,987 ounces of gold at an average cash operating cost of $548 per ounce compared to 18,770 ounces of gold at an average cash operating cost of $349 per ounce in Q1 2009. Other than exchange rates, which caused an increase in cash operating costs of $104 per ounce compared to Q1 2009, cash operating costs were higher in Q1 2010 due to: (a) lower grades brought about by higher than planned dilution, (b) distributing fixed operating costs over fewer ounces and (c) costs related to a scheduled 10-day maintenance.

The following was achieved at Turmalina during Q1 2010:

    
    -   Mine production totaled 150,102 tonnes at an average run-of-mine
        ("ROM") grade of 4.14 grams per tonne compared to 128,861 tonnes of
        ore at a ROM grade of 5.47 grams per tonne in Q1 2009.
    -   Ore processed through the mill totaled 150,733 tonnes at an average
        feed grade of 4.16 grams per tonne compared to 120,173 tonnes at an
        average feed grade of 5.38 grams per tonne in Q1 2009.
    -   The plant recovery rate averaged 88% in Q1 2010 compared to 90% in Q1
        2009.
    -   Mine development totaled 1.3 km.
    

Paciência Operations

In Q1 2010, Paciência produced 14,236 ounces of gold at an average cash operating cost of $650 per ounce compared to 14,099 ounces of gold at an average cash operating cost of $490 per ounce in Q1 2009. Cash operating costs were higher primarily due to (a) a significantly stronger Brazilian real, which caused an increase in cash operating costs of $147 per ounce compared to Q1 2009 (b) mining costs tied to the ramp-up of operations from the NW1 zone and (c) costs related to a 10-day scheduled maintenance. These factors offset the higher grades achieved at the St. Isabel Mine.

The following was achieved at Paciência during Q1 2010:

    
    -   Mine production from the St. Isabel Mine totaled 84,721 tonnes at an
        average ROM grade of 3.18 grams per tonne compared to 110,663 tonnes
        of ore at an average ROM grade of 2.86 grams per tonne in Q1 2009.
    -   Mine production from the Pilar Mine averaged 41,243 tonnes at an
        average ROM grade of 3.87 grams per tonne compared to 38,673 tonnes
        at an average grade of 4.35 grams per tonne in Q1 2009.
    -   Mine production from the Palmital Mine averaged 17,296 tonnes at an
        average ROM grade of 4.28 grams per tonne. The Palmital Mine was not
        in operation in Q1 2009.
    -   Mine production from the NW1 Zone averaged 18,418 tonnes at an
        average ROM grade of 3.20 grams per tonne. The NW1 Zone did not
        produce ore in Q1 2009.
    -   Ore processed through the mill totaled 147,847 tonnes with an average
        feed grade of 3.32 grams per tonne compared to 154,737 tonnes with an
        average feed grade of 3.26 grams per tonne in Q1 2009.
    -   The plant recovery rate averaged 93% in Q1 2010 compared to 91% the
        prior year.
    -   Mine development at the St. Isabel Mine totaled 0.9 km, 0.6 km at the
        NW1 Zone, 0.5 km at the Palmital Mine and 0.6 km at the Pilar Mine
        during Q1 2010.
    

Caeté Project

The construction of the Caeté Project continues to move on-schedule and is nearing completion. Commissioning is slated to begin in May 2010 using development ore from the adjacent Roça Grande Mine. During Q1 2010, 0.6 km of mine development was completed at the Roça Grande Mine.
