    Mr. Titcomb will provide details of several new initiatives underway at
the Company's mining operations and expanded exploration program in Brazil.
The highlights include:

    Down Strike Deep Drill Program
    ------------------------------
    Jaguar is initiating a 'go-deep' drill program where several new holes
will be drilled to depths of up to 1,000 meters in selected ore zones at
Turmalina, Roça Grande and Pilar. This program aims to prove the extension of
mineralization that Jaguar's exploration team now believes exists to depth
based on the geological models developed to-date. The Company has acquired a
significant amount of geological data from extensive drilling, which continue
to indicate that Jaguar's three main projects, where resources have been
measured and reported, are open at depth and most of them along strike.
Additional details from this initiative will be provided to investors as
information becomes available.

    Accelerate Expansion of Turmalina
    ---------------------------------
    Accelerate the Expansion I of Turmalina to produce over 100,000 oz of
gold by 2009. The expansion is expected to be completed by the third quarter
of 2008 processing additional ore from the nearby Satinoco ore body, which
will be accessed from a new cross cut from the existing ramp system and mine
entrance. This initiative will require a modest expansion of the leaching
circuits at the existing processing facility as sufficient milling and
grinding capacity exists to exceed 1,500 tpd. It will also require additional
underground development and some new equipment. Total capital costs for the
Expansion I are estimated at $8 million, most of which will be invested in
mine expansion. The feasibility study, which will convert additional resources
to reserves, is underway and scheduled for completion in December 2007.

    Expansion Extends Feasibility Period for Caeté Offsetting Delay
    in Power Supply
    ---------------------------------------------------------------
    New discoveries of deeper mineralized zones at the Roça Grande property,
coupled with a revised timing of availability of sufficient power resources
required for the new processing plant, allows more time for the Company to
develop the Caeté Project feasibility study. Previously, Jaguar expected to
complete the feasibility study during the current quarter and commission Caeté
in the third quarter of 2008. The new schedule anticipates that the
feasibility study will be completed during the first quarter of 2008 and
commission the facility during the second quarter of 2009. The Company intends
to use the additional time to significantly expand mineral resources through
deeper drilling and extend the mine life beyond the present scope detailed in
the current findings of the feasibility study. Jaguar has elected not to
acquire power generation equipment to internally generate electricity, which
would allow the Company to maintain the previous schedule. The power contract
and mine/plant implementation licenses (LI) have been secured for the 2009
start-up.

    Eliminate Gold Hedge
    --------------------
    The Company has made the decision to terminate the existing hedge program
and provide 100% of the upside in gold prices to Jaguar's investors.
    Commenting on these latest developments, Mr. Titcomb stated, "Given the
geological setting in which we operate in Brazil, we continue to believe
Jaguar's gold resource base could be expanded, allowing us to sustain an
operating target of more than 400,000 oz/yr for ten years. Our exploration
team has defined the continuity and geometry of the main projects to a depth
of 200-400 meters, confirming resources and that mineralization is open at
depth as well as on strike. Our team now has the confidence to drill these
structures to a depth of 700-1,000 meters. This program is expected to provide
significant upside growth to our resource base faster than previously thought
possible."
    Concerning expansion and new development of operations, Mr. Titcomb
added, "With the operating success we have achieved at Turmalina, coupled with
the additional resources now available to us from the Satinoco ore body, we
are deploying the resources, both human and financial, to this operation today
to expand gold production at Turmalina faster than previously planned. The
economic benefits far out-weigh the alternatives and provide a superior return
on investment. As a result of strong local demand for power in Brazil, an
unexpected delay in available electricity to power our Caeté Project has
postponed our development program for this new operation by approximately six
months. Investing the capital to produce power internally to maintain our
original schedule would be costly and imprudent. We have obtained guarantees
from CEMIG, the local power company, that Caeté's power needs will be in-place
by the first quarter of 2009, the date we now expect to begin the
commissioning of that operation. This delay provides us with additional time
to further delineate and measure newly identified mineralization located at
depth to Caeté's Roça Grande ore body. Moreover, it allows us to re-position
the Caeté Project construction team over to Turmalina to devote their efforts
to the expansion, achieving greater capacity from existing infrastructure."
    As it concerns the gold hedge, Mr. Titcomb added, "Our decision to
eliminate the hedge position that we placed in order to obtain the project
financing for Turmalina required us to examine our available capital against
our overall capital commitments. By moving the development of the Caeté
Project back by two quarters, due to the shortage of electricity and the
opportunity to add initial design capacity, we are now better able to settle
the hedge and reward our shareholders with 100% of the upside if gold prices
continue to rise."
    Jaguar Mining will be hosting a tour of its operations in Brazil October
16-19 and is open to qualified investors and analysts. If you have an interest
