              SILVER RESOURCES INCREASE TO OVER 300 MILLION OUNCES
                           AT IMA'S NAVIDAD DISCOVERY

IMA EXPLORATION INC. (IMR-TSX.V,  IMXPF-OTC.BB) is pleased to report the results
of a resource  estimate on the Calcite Hill  deposit at it's 100% owned  Navidad
Project in Patagonia,  Argentina. The Indicated Resources at the Navidad Project
now totals 300.7 million  ounces of silver and 1.27 million tonnes of lead (92.8
million tonnes @ 101 g/t silver and 1.36% lead).  Ongoing drilling  continues to
define additional  mineralization in the area of the Calcite Hill deposit beyond
the resource estimate published here.

With the  addition for the first time of  Indicated  and  Inferred  Resources at
Calcite Hill, IMA's Exploration Team has now defined continuous silver resources
(Indicated  and Inferred)  over a 2.3 kilometre  strike length along the Navidad
Trend. Ongoing drilling is targeting significant  extensions to this world-class
silver resource;  additional  surface work continues to better define additional
known  mineralization  at the  Argenta  and  Esperanza  Trends.  In  addition to
exploring for new resources,  the company  continues to better define and expand
resources  around the margins of Galena Hill,  the Connector  Zone,  and Navidad
Hill. It is expected that updated  resource  estimations will be undertaken once
this phase of drilling is complete.

The new resource estimate was prepared by Neil Burns,  M.Sc.,  P.Geo. of Snowden
Mining  Industry  Consultants  Inc., who is an Independent  Qualified  Person as
defined by National Instrument 43-101. The Calcite Hill estimate relied on assay
results  from 35 diamond  drill holes  covering an area of  approximately  550 x
150-250 metres. Most of the estimated resource lies at relatively shallow depths
starting  at 50 to 80  metres  and  extending  to 100 to 180  metres  below  the
surface. Snowden created a block model (block size 12.5 x 12.5 metres in plan by
10 metres in depth) of the Calcite  Hill  deposit and coded this model into four
domains based on geological  interpretation.  Grade was estimated using multiple
indicator kriging techniques within the higher-grade domain and ordinary kriging
with  appropriate  grade capping  elsewhere.  Densities were assigned to a block
model using a nearest  neighbour  estimate from  composited data determined from
density  measurements of entire boxes of whole core.  Average  densities used to
calculate  the tonnage at various  AgEq  cut-off  grades are shown in the tables
below. A small portion of the previously reported Navidad Hill Inferred Resource
has been upgraded to the Indicated category and included within the Calcite Hill
estimate.  The Navidad Hill  resources have been restated above to reflect these
minor  changes.  Please  note  that  the  Project  database  at the time of this
estimation comprised 174 diamond drill holes totalling 27,982 metres. Currently,
194 holes have been completed totalling over 32,200 metres.

Tables  showing the breakdown of estimated  resources at Calcite Hill at various
silver  equivalent   cut-off  grades  are  shown  below.   Complete  tables  and
grade-tonnage curves showing the resource estimates for all the Navidad deposits
at   various   cut-off   grades  are   available   at  the   company's   website
(WWW.IMAEXPLORATION.COM).  The base-case 50 g/t silver equivalent (AgEq) cut-off
was chosen as it reflects a contained  gross metal value that is similar to many
bulk-tonnage  operations  worldwide.  No economic  analysis  has been applied to
determine this figure; resources tabulated at other cut-off grades are presented
below for  comparison  purposes.  It is  important  to note that at Calcite Hill
doubling the cut-off to 100 g/t AgEq only reduces the contained ounces of silver
by 21%;  applying  this higher cut off to the project total  resources  produces
only a 14%  reduction in  contained  silver  showing the robust  nature of these
deposits.  Silver equivalent values were calculated using silver,  lead, copper,
and zinc grades and the same metal  prices as were used in the  previous  Galena
Hill and Navidad Hill resource estimates1.  The silver equivalence formula makes
no allowances for variable metal recoveries.

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, Navidad Hill and Connector Zone Indicated Resources remain
     unchanged from the Phase I and II resource  estimations released on May 25,
     2004 and December 1, 2004 except for restating of the Navidad Hill Resource
     where a small  change was made at the common  border with the Calcite  Hill
     resource.
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.
