NEWS RELEASE                                                   December 01, 2004

                 NAVIDAD PROJECT INDICATED RESOURCE INCREASES BY
                       61 MILLION OUNCES CONTAINED SILVER

IMA  EXPLORATION  INC. (IMR - TSX.V,  IMXPF - OTC.BB) is pleased to announce the
results of the Phase II resource  estimate at it's 100% owned Navidad project in
Patagonia,  Argentina.  The resource  estimate was  completed by Snowden  Mining
Industry  Consultants Inc. using results from IMA's recently  completed Phase II
drill  program  that  tested the  Navidad  Hill and  Connector  Zones.  Both the
Indicated and Inferred  Resources at the Navidad project have been significantly
increased; the new total resources are currently estimated at:

INDICATED RESOURCE (GALENA HILL, NAVIDAD HILL AND CONNECTOR ZONES)

        -  268 MILLION OUNCES OF CONTAINED SILVER AND 1,175,600 TONNES LEAD.
        -  80.8 MILLION TONNES AT 103 G/T SILVER AND 1.45% LEAD
           * Estimated using a 50 g/t silver equivalent1 cut-off grade.

INFERRED RESOURCE (GALENA HILL, NAVIDAD HILL AND CONNECTOR ZONES)

        -  39.3 MILLION OUNCES OF CONTAINED SILVER AND 70,500 TONNES LEAD.
        -  15.7 MILLION TONNES AT 78 G/T SILVER AND 0.45% LEAD
           * Estimated using a 50 g/t silver equivalent1 cut-off grade.

Detailed review of the geological  interpretation and block model shows that the
Navidad Hill Deposit remains open and is insufficiently  drill tested in several
areas. The Phase III drill program  currently  underway will more fully test the
boundaries  of the Navidad  Hill zone,  with the intent to increase  the Navidad
Hill Indicated Resource.

Recent discoveries of new zones of silver  mineralization on surface (Loma de la
Plata and Sector Zeta) and the large scale potential at Calcite Hill as shown by
hole  88  (72.3m  of 202 g/t  silver)  clearly  demonstrate  the  potential  for
continued  significant  resource growth at the Navidad  Project.  The Company is
very  encouraged  by the results of this  resource  estimate and is committed to
steadily increasing the total silver resource at the Navidad Project.

The  Phase II  resource  estimate  was  performed  by  Snowden  Mining  Industry
Consultants Inc (Neil Burns,  M.Sc.,  P.Geo.,  Independent  Qualified Person, as
defined by National  Instrument  43-101).  Snowden  created a block model (block
size 12.5 x 12.5 x 10m) of the  Navidad  Hill and  Connector  Zones,  coded this
model into multiple domains based on geologic interpretation, and then estimated
grade using Multiple Indicator Kriging techniques.  The new resource estimate at
the Connector  Zone replaces  portions of the  previously  reported  Galena Hill
Inferred Resource, however, the Galena Hill Indicated Resource (see May 25, 2004
release) remains unchanged.

A table  showing the  breakdown of Indicated  and Inferred  Resources at Navidad
Hill,  the Connector  Zone,  and Galena Hill at cut-off grades of 50 and 100 g/t
silver equivalent1 are presented below.

The Navidad Hill resource  estimation  was performed  using data from 41 diamond
drill holes drilled within an area of approximately 400m x 350m. The majority of
the 15.2  million  tonne  resource  is  located  within  less than 100m from the
surface and Snowden has classified the majority of it as Indicated.

At the Connector Zone estimated  resources are primarily  classified as Inferred
(see table  above) as much of the zone has been  drilled  with  relatively  few,
wide-spaced  holes (18 drill  holes  covering  a strike  length of 600m).  As at
Navidad Hill, the Connector Zone remains open in several  directions and will be
more fully tested during the Phase III drill  campaign.  It is anticipated  that
ongoing drilling will  significantly  increase the current Indicated Resource at
the  Connector  Zone by converting  Inferred to Indicated  Resources and perhaps
also extending the mineralized zone.

Notes:

1.   Silver  equivalent  calculated  using  US$5.50/oz  silver,  $0.30/lb  lead,
     $1.10/lb  copper,  and $0.40/lb  zinc.  (AgEq = Ag +  (%Pb*10,000/242.5)  +
     (%Cu*10,000/66.1) + (%Zn*10,000/181.9).  No attempt has been made to adjust
     these  relative  values  by  accounting  for  metallurgical  recoveries  as
     insufficient  or no  information  is  available to do so. Metal prices have
     been left  unchanged  from the prior estimate at Galena Hill in May 2004 in
     order to simplify comparisons to the prior estimate.
2.   The Galena  Hill  Indicated  Resource  remains  unchanged  from the Phase I
     resource estimation released on May 25, 2004.
3.   Strict quality control and quality assurance  procedures have been observed
     at all stages of data collection leading to this resource. Please see IMA's
     website   (www.imaexploration.com)   for  a  detailed   overview  of  these
     procedures.
4.   Resource categories  (Indicated and Inferred) used here and the preparation
     of this resource  estimate conform to Industry Best Practices  standards as
     set out by National  Instrument 43-101 "Standards of disclosure for mineral
     projects" and those of the 2000 Canadian  Institute of Mining,  Metallurgy,
     and Petroleum (the "CIM") "Standards on Mineral Resources and Reserves".
5.   A National  Instrument  43-101  Technical  Report  documenting  the Snowden
     Resource Estimate will be filed at www.sedar.com as is required by Security
     Commission regulations.
6.   An `Inferred Mineral Resource' is that part of a Mineral Resource for which
     quantity and grade or quality can be  estimated on the basis of  geological
     evidence and limited  sampling and  reasonably  assumed,  but not verified,
     geological  and  grade  continuity.   The  estimate  is  based  on  limited
     information  and sampling  gathered  through  appropriate  techniques  from
     locations such as outcrops, trenches, pits, workings and drill holes.
7.   An  `Indicated  Mineral  Resource'  is that part of a Mineral  Resource for
     which   quantity,   grade  or  quality,   densities,   shape  and  physical
     characteristics,  can be estimated with a level of confidence sufficient to
     allow the appropriate application of technical and economic parameters,  to
     support mine  planning  and  evaluation  of the  economic  viability of the
     deposit.  The estimate is based on detailed and  reliable  exploration  and
     testing information gathered through appropriate  techniques from locations
     such as outcrops,  trenches, pits, workings and drill holes that are spaced
     closely  enough  for  geological  and  grade  continuity  to be  reasonably
     assumed.
