                          NEWS RELEASE - APRIL 5, 2006


                   PHASE IV DRILLING UPDATE FOR IMA'S NAVIDAD

IMA EXPLORATION INC.  (IMR-AMEX,  IMR-TSX.V) is pleased to announce results from
35 diamond drill holes at its Navidad  Silver  Project in Patagonia,  Argentina,
from the Phase IV drilling  programs that commenced in January of 2006. Phase IV
drilling to date has focused on further defining the Calcite NW and Calcite Hill
deposits, as well as testing of several geological/geophysical targets away from
the main mineralized trends.

Highlights  of the drilling at Calcite NW include hole NV06-262 with 25.2 metres
(m) averaging 146 grams/tonne  (g/t) silver including a higher-grade  section of
8.54m  averaging  385 g/t silver,  as well as NV06-264,  which  contained  28.4m
averaging 127 g/t silver including 6.85m of 455 g/t silver (Table 1). At Calcite
Hill  hole  NV06-272,  on the  northern  limit of the known  resource  boundary,
returned 9.86m averaging 401 g/t silver. The zone remains open towards the north
at shallow depths.

A small  area of Galena  Hill has also been  drilled  on tight  centres to allow
calculation  of the optimal  drill  spacing  and to collect  more  material  for
metallurgical  testing.  As the Phase IV program  continues  drilling  will also
target:  1) the Esperanza  Trend,  2) delineation of the high-grade  mineralized
zone at Loma de la Plata,  which has only been  tested by 5 drill  holes to date
(News  Release 24,  October 13, 2005),  and 3) initial  testing of other targets
located along the 8km Argenta Trend.

As expected,  infill  drilling at Galena Hill produced long intercepts of silver
and lead  mineralization.  An example of one of the Galena Hill infill  holes is
NV06-275,  with 120m  containing  218 g/t silver and 4.8 percent (%) lead with a
higher-grade, upper-part of 27.8m, starting at just 33m depth, that contains 539
g/t silver and 9.3 % lead.  Similarly,  hole NV06-279 produced 156.8 m averaging
121 g/t silver and 4.8 % lead including a higher-grade interval of 42m averaging
231 g/t silver and 10.2 % lead in its upper portion. For convenience, the silver
equivalent  values  including  lead have been shown in the table of results.  In
many cases the lead accounts for as much as half of the potential metal value at
Galena  Hill  (see  formula  in the  foot  notes  of table  for  details  of the
calculation method).

Galena  Hill infill  drilling  will  determine  the  optimal  drill  spacing and
orientation  required to upgrade the resource from the indicated to the measured
category.  The holes released  represent  three section lines of five holes each
with  spacing  between the hole  collars and lines of 25m. All of the holes were
drilled  towards  grid north at -75  degrees.  Additional  infill  holes will be
drilled  oriented -75 degrees grid south on  intermediate  section  lines at 25m
collar  spacing,  thereby  reducing the section  lines  spacing to 12.5m.  Prior
drilling was done at a section spacing of roughly 80 metres with holes spaced at
approximately 60 metres.

The results of holes  released  represent  6,633  metres of drilling of the more
than 9,000  metres  already  drilled in 2006,  bringing  the life of the project
total to over 50,000 metres.  Reconnaissance  drilling  included 4 holes drilled
between the  Esperanza  and Argenta  trends.  Drilling at Calcite NW included 14
holes,  while  drilling at Calcite  Hill  included 2 holes.  An  infill-drilling
program at Galena Hill comprised 15 holes. The drill is currently working on the
Esperanza Trend.

Notes:

1.   True thickness has not been calculated for these holes.
2.   All length weighted averages (LWA) are "uncut" i.e. have no grade capping.
3.   Silver  equivalent  calculated using  US$6.00/oz  silver and $0.35/lb lead.
     (AgEq = Ag +  (%Pb*10,000/250).  No attempt  has been made to adjust  these
     relative values by accounting for metallurgical recoveries, as insufficient
     information  is  available to do so. This is the same method as used in the
     resource calculation release on February 16, 2006.
4.   A  complete  list of all  results  to date is  available  on IMA's  website
     (www.imaexploration.com).
