            Jaguar Mining Reports Q2 2010 and YTD 2010 Earnings

            JAG - TSX/NYSE

            CONCORD, NH, Aug. 9 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the
"Company") (JAG: TSX/NYSE) reports its financial and operational results for
the period ended June 30, 2010. All figures are in U.S. dollars unless
otherwise indicated.

            <<
            Q2 2010 Highlights

            -   Q2 2010 net loss of $5.9 million or ($0.07) per basic and fully
                diluted share compared to net income of $9.7 million or $0.12 per
                basic and fully diluted share in Q2 2009. Net income for Q2 2010 was
                adversely impacted by significantly higher cash operating costs
                caused by higher-than-planned dilution at its underground mines,
                especially at Turmalina.

            -   Q2 2010 gold sales decreased to 30,646 ounces at an average price of
                $1,203 per ounce yielding revenue of $36.9 million compared to Q2
                2009 gold sales of 35,561 ounces at an average price of $922 per
                ounce and revenue of $32.8 million.

            -   Q2 2010 gold production totaled 30,586 ounces at Turmalina and
                Paciencia at an average cash operating cost of $746 per ounce
                compared to 35,806 ounces at an average cash operating cost of $447
                per ounce during the same period last year (see Non-GAAP Performance
                Measures). The 15% drop in gold production and the net increase in
                cash operating costs from the prior year were attributable to a
                significant decrease in run-of-mine ("ROM") grades, primarily caused
                by abnormally high dilution.

            -   Q2 2010 average feed grade was 3.17 g/t compared to 4.18 g/t during
                Q2 2009. The Company continued to encounter geo-mechanical issues at
                level 3 in the Turmalina Ore Body A ore shoot, which resulted in
                dilution averaging 30%, double what was planned. As a consequence,
                less ore was shipped from Ore Body A to the Turmalina Plant.
                Management believes this will continue to have an impact on the
                grades and production at the Turmalina operation through the balance
                of 2010 until the development of level 4 is completed and employing
                the new mining method.

                The decision was made in early 2010 to change the mining method from
                selective stoping to cut-and-fill at level 4 and below in the
                Turmalina Ore Body A. This changeover has been slower than planned
                due to geo-mechanical issues, specifically in developing the access
                ramp within level 4 of Ore Body A. Management has tested and believes
                these modifications will significantly contribute to higher ROM
                grades in early 2011. A complete review and reconciliation of the
                grades mined and processed, compared to what was anticipated from the
                block model, confirms there is no change in the overall geology, i.e.
                no decrease in in-situ grades. The primary issue is fully
                implementing different mining techniques.

            -   Q2 2010 gross profit decreased to $2.1 million from $9.1 million in
                Q2 2009.

            -   Q2 2010 cash provided by operating activities (see non-GAAP measures)
                was $4.5 million compared to $12.6 million in Q2 2009. The decrease
                was primarily due to the higher average operating cash costs.

            -   The formal inauguration of the Company's Caete gold operation took
                place on June 23, 2010. The Caete Plant was completed in late May and
                the crushing circuit was activated on May 25, 2010. Testing of the
                milling circuit was conducted in early June and the plant was charged
                with ore on June 12, 2010, formally entering the commissioning phase.

            -   Jaguar invested $36.5 million in growth projects in Q2 2010 compared
                to $20.1 million invested in Q2 2009.

            -   As of June 30, 2010 the Company held cash holdings of $65.4 million,
                including $5.9 million in short-term certificate of deposits and
                $0.9 million of restricted cash.
            >>

            Commenting on the Q2 2010 results, Daniel R. Titcomb, Jaguar's President
and CEO stated, "Our second quarter operational and financial performance was
sharply below our plans as a result of geo-mechanical rock issues at the
Turmalina operation. To overcome this issue, our technical team has been
changing the mining method from selective stoping to cut and fill, however at
a slower pace than planned. We are confident the transition to a cut-and-fill
method will decrease dilution and lead to improved feed grades into the plant.
Although still early, we are achieving sharp improvements in the limited
number of cuts mined during July with overall dilution now running
approximately 12 to 15%. However, we will not have the new development and
sequencing in-place until later this year required to increase the tonnage
from the primary ore body at Turmalina to meet our previous targets."
            Mr. Titcomb added, "Our plan to reach mid-tier status remains intact.
However, we will not be in a position to provide updated production and CAPEX
figures until our engineering team completes the review of new technologies
that management believes should sharply reduce our capital requirements and
lower our operating costs. This analysis will be completed later this fall.
Based on our present mine plans, which include the changes in mining methods
at Turmalina, feed grades should improve in 2011. Moreover, with the
contribution of the Caete operation, which is ramping-up as anticipated, we
estimate 2011 gold production could rise nearly 40% over this year's revised
outlook."

            <<
            1st Half 2010 Highlights

            -   Net loss of $10.5 million or ($0.13) per basic and fully diluted
                share for the six months ended June 30, 2010 compared to net income
                of $14.5 million or $0.20 per basic share and $0.19 per fully diluted
                share for the same period in 2009. The net loss for 2010 was
                unfavorably impacted mostly by higher costs on fewer ounces sold
                during Q2 2010 but also by the requirement to recognize non-cash
                interest expense associated with Jaguar's 4.5% senior convertible
                notes, which totaled $4.0 million for the first half of 2010.

            -   First half 2010 gold sales totaled 67,535 ounces at an average price
                of $1,148 per ounce yielding revenue of $77.5 million compared to
                gold sales of 71,440 ounces at an average price of $925 per ounce and
                revenue of $66.1 million for the same period in 2009.

            -   First half 2010 gold production totaled 61,810 ounces at Turmalina
                and Paciencia at an average cash operating cost of $671 per ounce
                compared to 68,675 ounces at an average cash operating cost of $434
                per ounce during the same period last year (see Non-GAAP Performance
                Measures). The Company's gold production for the six months ended
                June 30, 2010 decreased 16% from the comparable period in 2009 due
                largely to the shutdown of oxide leaching operations at Sabara and
                the geo-mechanical issues at Turmalina.

            -   Gross profit for the six months ended June 30, 2010 decreased to
                $9.5 million from $20.4 million during the same period in 2009.

            -   Cash provided by operating activities during the first half of 2010
                totaled $11.2 million compared to $19.3 million during the first half
                of 2009.

            -   Jaguar invested $73.4 million in growth projects during the first
                half of 2010, up from the $25.6 million invested during the same
                period in 2009. The development of the new Caete operation
                represented the largest investment during the first half of 2010.

            -   The Company achieved underground development targets of 9.2 km for
                the six months ended June 30, 2010; on plan.

            Non-GAAP Performance Measures

            The Company has included the non-GAAP performance measures discussed
below in this press release. These non-GAAP performance measures do not have
any standardized meaning prescribed by Canadian GAAP ("GAAP") and, therefore,
may not be comparable to similar measures presented by other companies. The
Company believes that, in addition to conventional measures prepared in
accordance with GAAP, these non-GAAP measures provide certain investors with
additional information that will better enable them to evaluate the Company's
performance. Accordingly, these Non-GAAP measures are intended to provide
additional information and should not be considered in isolation or as a
substitute for measures of performance prepared with GAAP.
            The Company has included cash operating cost per ounce processed because
it believes these figures are a useful indicator of a mine's performance as
they provide: (i) a measure of the mine's cash margin per ounce, by comparison
of the cash operating costs per ounce to the price of gold; (ii) the trend in
costs as the mine matures; and, (iii) an internal benchmark of performance to
allow for comparison against other mines. Cash provided by operating
activities has also been included as an overall measure of cash generation
capability on a standardized basis. The definitions for these performance
measures and reconciliation of the non-GAAP measures to reported GAAP measures
are set out in the following tables.

            (1) Production costs do not include cost of goods sold adjustment of
                approximately $1.3 million, royalties of $1.1 million and CFEM tax of
                $368,000 for the three months ended June 30, 2010; and of goods sold
                adjustment of approximately $2.6 million, royalties of $2.6 million
                and CFEM tax of $778,000 for the six months ended June 30, 2010.
            (2) Under the Company's revenue recognition policy, revenue is recognized
                when legal title passes. Since total cash operating costs are
                calculated on a production basis, this change reflects the portion of
                gold production for which revenue has not been recognized in the
                period.
            (3) The basis for calculating cost per ounce produced includes the change
                to gold in process inventory, whereas the cost per tonne processed
                does not.

            About Jaguar Mining

            Jaguar is one of the fastest growing gold producers in Brazil with
operations in a prolific greenstone belt in the state of Minas Gerais and has
plans to develop the Gurupi Project in northern Brazil in the state of
Maranho. Jaguar is actively exploring and developing additional mineral
resources at its approximate 575,000-acre land base in Brazil. Additional
information is available on the Company's website at www.jaguarmining.com.

            The Company uses the financial measure "adjusted cash flows from
operating activities" to supplement its consolidated financial statements. The
presentation of adjusted cash flows from operating activities is not meant to
be a substitute for cash flows from operating activities presented in the
statement of cash flows in accordance with GAAP, but rather should be
evaluated in conjunction with such GAAP measures. Adjusted cash flows from
operating activities is calculated as operating cash flow excluding the change
in non-cash operating working capital. The term adjusted cash flows from
operating activities does not have a standardized meaning prescribed by
Canadian GAAP, and therefore the Company's definitions are unlikely to be
comparable to similar measures presented by other companies. The Company's
management believes that the presentation of adjusted cash flows from
operating activities provides useful information to investors because it
excludes certain non-cash changes and is a better indication of the Company's
cash flow from operations. The non-cash charges excluded from the computation
of adjusted cash flows from operating activities, which are included in the
Statements of Cash Flows prepared in accordance with Canadian GAAP, are items
that the Company does not consider to be meaningful in evaluating the
Company's past financial performance or the future prospects and may hinder a
comparison of its period to period cash flows.

            Forward Looking Statements

            Certain statements in this press release constitute "forward-looking
statements" within the meaning of the U.S. Private Securities Litigation
Reform Act of 1995 and Canadian securities legislation. This press release
contains forward-looking statements, including statements concerning, expected
grades, revenue and cash flow and estimates for 2010, production and cash
operating cost outlooks. Forward-looking statements involve known and unknown
risks, uncertainties and other factors, which may cause the actual timing of
commissioning, production and results of operations to be materially different
from any future results or performance expressed or implied by the
Forward-Looking Statements. These factors include the inherent risks involved
in the exploration and development of mineral properties, the uncertainties
involved in interpreting drilling results and other geological data,
fluctuating gold prices and monetary exchange rates, the possibility of
project cost delays and overruns or unanticipated costs and expenses,
uncertainties relating to the availability and costs of financing needed in
the future, uncertainties related to production rates, timing of production
and the cash and total costs of production, changes in applicable laws
including laws related to mining development, environmental protection, and
the protection of the health and safety of mine workers, the availability of
labour and equipment, the possibility of labour strikes and work stoppages and
changes in general economic conditions. Although the Company has attempted to
identify important factors that could cause actual actions, events or results
to differ materially from those described in forward-looking information,
there may be other factors that cause actions, events or results to differ
from those anticipated, estimated or intended. These forward-looking
statements represent the Company's views as of the date hereof. Subsequent
events and developments could cause the Company's views to change. The Company
does not undertake to update any forward-looking statements, either written or
oral, that may be made from time to time by or on behalf of the Company
subsequent to the date of this discussion other than as required by law. For a
discussion of important factors affecting the Company, including fluctuations
in the price of gold and exchange rates, uncertainty in the calculation of
mineral resources, competition, uncertainty concerning geological conditions
and governmental regulations and assumptions underlying the Company's
forward-looking statements, see the "CAUTIONARY NOTE" regarding
forward-looking statements and "RISK FACTORS" in the Company's Annual
