Jaguar Mining and Xstrata Form Joint Venture to Explore Promising Greenstone Belt in Northern Brazil



    JAG - TSX

    Preliminary Exploration Effort Reveals Significant Mineralization

    CONCORD, NH, March 12 /CNW/ - Jaguar Mining Inc. ("Jaguar" or "the
Company") (JAG-TSX) reports that it has entered into a formal agreement with
Xstrata plc ("Xstrata") for Jaguar to explore the Pedra Branca Gold Project
("Project") in the State of Ceara in Northern Brazil. Under the terms of the
agreement, Jaguar and Xstrata will form a joint venture company or companies
to mine economic gold deposits in the Project. For an aggregate fee of
US$150,000 over the next two years, Jaguar will have the option to hold a
51 percent ownership interest in the new enterprise by investing an aggregate
US$3.85 million in exploration expenditures within the next four years. Jaguar
is subject to annual exploration expenditure targets for each year in which it
maintains the option. Jaguar has the opportunity to increase its ownership
interest in certain gold deposits to 60 percent through a further investment
of US$3.0 million by the fifth anniversary of the agreement, subject to the
rights of Xstrata to return to their 49 percent interest through additional
contributions to the joint venture, for certain properties which have gold
deposits of two million ounces or more. Certain properties within the Project
that are dominated by base metal deposits, or which have gold deposits of less
than one million ounces, may be held in different ownership percentages and be
subject to different conditions, or removed from the joint venture.
    The Jaguar-Xstrata joint venture has mineral rights to 37 concessions
totaling approximately 159,000 acres in a 65-km shear zone. The concessions
are located in and around municipal areas with excellent infrastructure. The
area is characterized by relatively dry weather, facilitating year-round
operations.
    Xstrata's exploration team has performed preliminary work on two large
anomalies referred to as Coelho and Mirador. The initial exploration work on
these two targets include:

    a. Geophysical mapping
    b. Drainage geochemistry: 625 samples
    c. Soil geochemistry: 6,570 samples
    d. Trenches: 2,822m
    e. Channel and ship samples: 2,249 units

    The relatively shallow work to-date on the Coelho and Mirador targets has
provided some promising results with respect to gold mineralization averaging
between 2.3-2.5 g/t observed in the 21 surface samples taken by Xstrata. Based
on this information, which was provided to Jaguar in greater detail, Jaguar
intends to conduct further exploration at the Project to determine the extent
of the gold resources at Pedra Branca. If mineralization is determined to
exist in commercial quantities, Jaguar intends to prepare and file a technical
report consistent with National Instrument 43-101 at the appropriate time.
    For the most part, the mineralized formations uncovered by Xstrata's
preliminary efforts are open along the extremity and lead both companies'
geologists to believe the area has significant potential for gold
mineralization, which could include the presence of both oxide and sulfide
formations in large structures.
    The preliminary exploration program carried out by Xstrata only covered
25 km of this zone, with 10 km of soil anomalies identified. Jaguar intends to
develop and execute a comprehensive exploration program at the Project during
2007 and 2008 to further delineate and measure the gold mineralization through
further trenching and diamond core drilling.
    Commenting on the venture with Xstrata, Daniel R. Titcomb, Jaguar's
President and CEO stated, "We are very pleased and excited to be partnering
with Xstrata in a separate greenstone belt geological setting that could
contain large gold-bearing structures. We take pride that Xstrata sought to
partner with Jaguar on this exciting venture, further strengthening our belief
that Jaguar has one of the finest exploration and operating teams in the
industry."

development, environmental protection, and the protection of the health and
safety of mine workers, the availability of labor and equipment, the
possibility of labor 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
