NEWS RELEASE                                                    OCTOBER 13, 2004


            IMA INTERSECTS 28 METRES OF 1,115 G/T (32.6 OZ/T) SILVER
                                 AT NAVIDAD HILL

IMA  EXPLORATION  INC. (IMR - TSX.V,  IMXPF - OTC.BB) is pleased to announce the
final results of the Phase II drill program at its 100% owned Navidad Project in
Patagonia,  Argentina.  Highlights of these results  include 28.15M OF 1,115 G/T
SILVER  (32.6 OZ/T)  INCLUDING  5.97M OF 4,579 G/T (133.7  OZ/T) IN HOLE 117 AND
58.68M OF 208 G/T SILVER (6.1 OZ/T) IN HOLE 112. In  addition to  expanding  the
limits of known alteration and mineralization  through ongoing surface work, the
Company  has  contracted  Snowden  Mining  Industry  Consultants  to  perform an
independent resource estimation at the Navidad Hill and Connector zones. Results
from this new resource estimation will be from zones outside of, and in addition
to the previously reported Galena Hill Indicated Resource of 63.6 million tonnes
grading 101 g/t silver,  1.76%  lead,  0.03%  copper and 0.24% zinc at a cut-off
grade of 50 g/t silver equivalent (see release dated May 25, 2004).

The twelve  reported  drill holes were all drilled at the Navidad Hill zone (see
attached  map).  Targets  included   structurally   controlled,   near  vertical
mineralized bodies (e.g. HOLE NV04-110: 61.50M OF 128 G/T SILVER INCLUDING 5.34M
OF  1,006  G/T  SILVER)  on  the  top  of  Navidad   Hill  and   gently-dipping,
stratigraphically-controlled  mineralization  in the area of hole 90 (e.g.  HOLE
NV04-117:  28.15M OF 1,115 G/T  SILVER).  Drill  holes 116 and 117  confirm  and
extend the  stratigraphically  controlled,  bonanza-grade  mineralization on the
southwest  flank of Navidad Hill first  discovered  with hole 90 (35.8M OF 2,850
G/T SILVER).

All data  resulting  from the  Phase  II  program  are now  being  verified  and
interpreted  prior to being handed over to Snowden.  This will include a careful
review of all QA/QC analytical data. Phase II drilling comprised 9,596 metres of
diamond  core  drilling  in 67 holes and 5,210 core sample  analyses,  including
quality control  samples,  bringing the life of the project totals to 18,456m in
120 holes and 10,548 core sample  analyses in less than one year since the first
hole was drilled.

Dr.  Paul  Lhotka is IMA's  Qualified  Person at the  Navidad  Project,  and has
overseen  all aspects of the  current  program.  An updated  summary of Phase II
results is available at IMA's  website  (www.imaexploration.com)  as are updated
maps showing the locations of all drilling completed to date on the project.

IMA Exploration Inc. has over 10 years experience in Argentina and is focused on
the exploration  and development of its 100% owned Navidad silver  discovery and
its property portfolio in the region.

Notes:
1.   All length weighted averages (LWA) are "uncut".
2.   True thicknesses have yet to be interpreted for these holes. True thickness
     in the case of  sub-vertical  structures  and  -45(Degree)  drill holes are
     likely to be approximately 70% of the intercept  length;  true thickness in
     the case of shallowly dipping  stratigraphically-controlled  mineralization
     is likely to be between 70 and 100% of the intercept length.
