NEWS RELEASE                                                      APRIL 19, 2005


            DRILLING CONTINUES TO EXPAND CALCITE HILL MINERALIZATION
                        AT IMA'S NAVIDAD SILVER DISCOVERY

IMA EXPLORATION INC (IMR-TSX.V,  IMXPF-OTC.BB) is pleased to report results from
diamond  drill  holes 162 to 174 at the  Calcite  Hill  zone on it's 100%  owned
Navidad  silver  project in  Patagonia,  Argentina.  Highlights  of the  current
results include 29.6M OF 236 G/T SILVER AND 5.38% LEAD IN HOLE 167, AND 51.0M OF
168 G/T SILVER IN HOLE 168.  Mineralization at Calcite Hill has now been defined
over a strike length of 500m and varies in horizontal  width from  approximately
50 to 150 metres and  vertical  thickness  from 10 to 110 metres  (see  attached
map). To date,  IMA has defined an Indicated  Resource of 268 million  ounces of
silver and 1.1 million tonnes of lead (80.8 million tonnes at 103 g/t silver and
1.45% lead using a 50 g/t silver  equivalent  cut-off) at Navidad  Hill,  Galena
Hill and the Connector Zone.

A new resource  estimate at Calcite Hill is planned to begin shortly and will be
conducted by Snowden  Mining  Industry  Consultants  based on the 36 drill holes
completed at Calcite Hill during Phase III (as of April 18, 2005).  To date, IMA
has completed  27,981m of core drilling in 174 holes taking the Navidad  Project
from an undrilled  prospect to one of the world's  largest  silver  resources in
just 17 months. The Calcite Hill mineralization is expected to add significantly
to the existing resource base.

In addition,  the company reports that Connors  Argentina S.A. is now on site at
Navidad to begin the  additional  10,000m that were added to the Phase III drill
program.  The primary  focus of this  program  will be to continue to expand the
high-grade silver-lead mineralization at Calcite Hill.

The  Calcite  Hill  zone  is  open  along  strike  to  the  northwest   where  a
silver-in-soil  anomaly extends for a further 1.4 km beyond the present limit of
drilling,  and also to the northeast in the area nearest Navidad Hill.  Complete
results from drill holes 162 to 174 are shown in Table 1, significant intercepts
to date from Calcite Hill include the following:

Silver  mineralization  at Calcite Hill is predominantly  hosted within the same
trachyandesite  volcanic rock and overlying mudstone which hosts  mineralization
at Galena Hill.  Mineralization  consists of two distinct styles, one consisting
of calcite-barite veinlets and breccias with argentite-acanthite,  native silver
and lesser galena and  chalcopyrite,  the other consisting of veins and breccias
containing medium-grained galena and rare native silver.
