 JAG - TSX/NYSE

VP Investor Relations Appointed; Q2 Earnings Conference Call Details
Included

CONCORD, NH, July 19, 2011 /CNW/ - Jaguar Mining Inc. ('Jaguar' or 'the Company') (JAG: TSX/NYSE) provided today a preliminary summary of its Q2 2011 operating
performance.  All figures are in U.S. dollars unless otherwise
indicated.

Q2 2011 Highlights

    --  Total production of 40,257 ounces of gold.
    --  Jaguar's established operations, Turmalina and Paciência,
        performed at or above targets in terms of gold production,
        grade and recoveries.
    --  The Caeté operation, which is still in ramp-up, was on plan in
        terms of tonnage but mechanical issues at its primary mill
        caused a setback in gold output.  The mill has been repaired
        and the Caeté plant is now operating at full capacity.
    --  Despite the mill outage at Caeté, Jaguar produced 15,375 ounces
        of gold in June, the second highest monthly production in the
        Company's history.
    --  Mine output totaled approximately 460,000 tonnes during the
        quarter, with nearly 44,000 ounces of metal produced.  However,
        mechanical issues caused approximately 4,000 ounces of gold
        metal to remain in stockpile.
    --  During the first half of 2011, the Company produced a total of
        81,706 ounces of gold.  This represents a 32% increase over the
        61,836 ounces produced in the first half of 2010.
    --  The average cash operating cost for the quarter was $799 per
        ounce, a 10% increase from Q1 2011.  Approximately $30 per
        ounce or 40% of this increase is associated with the further
        weakening of the U.S. dollar against the Brazilian real.  In
        addition, cash operating costs were significantly impacted by
        the mill outage at Caeté and some minor sequencing issues
        within the Roça Grande Mine, which resulted in lower than
        planned feed grades.  Increases in material and labor costs
        also contributed to the higher cash operating cost as compared
        to Q1 2011.
    --  Underground mine development of 6.1 km reached a new quarterly
        record, adding a significant number of faces, particularly at
        Caeté.
    --  Gold sales totaled 40,184 ounces at an average price of $1,507
        per ounce.
    --  The cash operating margin was a record $708 per ounce.
    --  As of June 30, 2011, the Company had cash and cash equivalents
        of $126.3 million, including $0.9 million of restricted cash.

Commenting on the Q2 2011 preliminary operating results, Daniel Titcomb,
Jaguar's President and CEO stated, 'We are pleased with the performance
of our mature operations, Turmalina and Paciência, which achieved their
planned targets for the quarter in terms of gold production, grades and
recoveries.  Most importantly, the technical geological issues we
encountered at Turmalina during the latter half of 2010 have been fully
resolved.'

'We did experience a significant mechanical issue during the quarter in
the primary mill at our new Caeté operation,' Titcomb continued. 'This
had the greatest impact on Q2's performance. Necessary repairs were
completed in early July and, despite this setback, in June our three
operations collectively produced at a run rate of 185,000 ounces per
year.  With the record underground development we achieved at all of
our mines during Q2, we believe our second half performance will
continue to post sequentially higher levels of production allowing us
to reach our targets.'
