NEWS RELEASE - APRIL 28, 2006
REVISED UPDATED RESOURCE ESTIMATE AND
METALLURGICAL RESULTS AT IMA'S NAVIDAD PROJECT
IMA EXPLORATION INC. (IMR-AMEX, IMR-TSX.V) is re-filing its February 16, 2006
News Release to correct typographical errors that were included in Table 2
below. This also resulted in the Company re-submitting its December 31, 2005
MD&A, as previously filed on SEDAR on April 3, 2006 to reflect this change. The
February 16, 2006 News Release as amended would now read as below:
IMA EXPLORATION INC. (IMR-AMEX , IMR-TSX.V) is pleased to announce the results
of an updated resource estimate at the Company's Navidad Project in Patagonia,
Argentina. This new estimate was completed to provide a high quality data set
for the ongoing scoping study and it includes results from recent infill and
perimeter drilling at the Galena Hill, Connector Zone, Navidad Hill, and Calcite
Hill deposits, and new resources at Calcite NW. This estimate now integrates
previous resource estimates of the individual deposits into one global block
model. Navidad Project Indicated Resources are now estimated at 93.4 MILLION
TONNES GRADING 102 G/T SILVER AND 1.41% LEAD FOR A TOTAL OF 305.7 MILLION OUNCES
OF CONTAINED SILVER AND 2.90 BILLION POUNDS OF LEAD (1.32 MILLION TONNES),
making the Navidad discovery a truly world class silver-lead deposit.
In addition, the Company is pleased to release highly encouraging preliminary
results from metallurgical testwork using thiosulphate to leach silver from
oxidized silver (pyrite) concentrates from Galena Hill. Pressure oxidation
followed by atmospheric leaching with thiosulphate has achieved silver
recoveries of up to 89%. These results are important as this process would allow
the production of silver metal on site using environmentally benign reagents.
With the addition of Indicated and Inferred resources at Calcite NW, the company
has now defined nearly continuous, near-surface resources at the Navidad Trend
over a strike length of 3.6 km at a cutoff grade of 50 g/t of silver equivalent
(AgEq(1)). No resources have yet been estimated along the 8 km long Argenta
Trend, where limited drilling on the Loma de la Plata target has returned
significant high-grade silver intersections. Table 1 shows the current resources
broken down by deposit at a cut-off grade of 50 g/t AgEq, tables 2 and 3 below
show project total Indicated and Inferred Resources at various cut-off grades.
More complete tables showing the resources broken down by deposit at different
cut-off grades and a map showing the distribution of currently estimated
resources are available at the company's website WWW.IMAEXPLORATION.COM.
This resource estimate was undertaken at the current time such that the unified
block model would be available to Pincock, Allen and Holt, of Denver, Colorado
who have recently initiated a scoping study that will examine the preliminary
technical, legal, social, environmental and economic aspects of the Navidad
Project. Mineralization at the recently discovered Calcite NW deposit is not yet
fully delineated, drilling is currently underway to determine the ultimate size
of this deposit.

The current resource estimate was prepared by Christine Standing, B.Sc.(Hons),
MAusIMM, of Snowden Mining Industry Consultants Pty Ltd who is an Independent
Qualified Person as defined by National Instrument 43-101 and has verified the
technical information relating to resources contained in this news release. A
technical report detailing the results of this resource estimate will be
publicly available on SEDAR (WWW.SEDAR.COM) within the next 45 days.
Reported base-case tonnages and grades were calculated using a cut-off grade of
50g/t silver equivalent. This cut-off was chosen as it reflects a contained
gross metal value that is similar to many bulk-tonnage operations worldwide. To
date, no analysis has been completed to determine the economic cut-off grade
that will ultimately be applied to the Navidad Project. Silver equivalent was
calculated using silver (US$6.00/oz) and lead (US$0.35/lb) values only; it did
not include any factors for variable metal recoveries. Previous resource
estimates have incorporated copper and zinc metal values in addition to silver
and lead in the silver equivalent. This change was made as metallurgical
testwork to date suggests that copper and zinc are not expected to be recovered
in sufficient quantity to add significantly to the value of concentrates
produced. This change is important as it has the effect of raising the silver
and/or lead grade required to include mineralized material in the resource, and
has reduced the tonnage but raised the silver and lead grades in each deposit.
Using the previous 50 g/t silver equivalent cut-off (including silver, lead,
copper, and zinc), the current Project total Indicated Resources would be: 108.0
million tonnes at 91 g/t silver and 1.25% lead for total contained metals of
316.5 million ounces silver and 2.98 billion pounds of lead. These numbers are
presented for comparison purposes only and investors are cautioned that they are
not valid as copper and zinc are not expected to be recovered and do not
contribute to the current resources.

Metallurgical testwork to date on material from the Navidad Project has focused
on using flotation technology to produce a high-grade, saleable lead concentrate
and variable-grade silver concentrates. In the case of Galena Hill, the pyritic
silver concentrates will require further on-site treatment to produce silver
dore (see Dec 1, 2005 press release). Recently, testwork performed at SGS
Lakefield under the direction of Dr. David Dreisinger, P.Eng. of Dreisinger
Consulting Inc. has shown that these silver concentrates are amenable to
pressure oxidation under neutral to alkaline conditions followed by atmospheric
leaching using calcium thiosulphate as a lixiviant. Preliminary bench-scale
testwork has produced silver recoveries of 87% after 24 hours and 89% after 72
hours of leaching. These tests were conducted on a very low-grade silver
concentrate (235 g/t silver), it is hoped that additional improvements in silver
recovery may be realized in future testwork on higher-grade concentrates. The
company is highly encouraged by these results as they indicate that the Navidad
Project could produce silver dore on-site using an environmentally benign
lixiviant rather than the more commonly used sodium cyanide. Calcium
thiosulphate is routinely used as fertilizer in the agricultural industry.

Notes:
1. 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.
2. 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.
3. Resource categories (Indicated and Inferred) used here and the preparation
of this resource estimate conform to National Instrument 43-101 "Standards
of disclosure for mineral projects" and those of the Canadian Institute of
Mining, Metallurgy, and Petroleum (the "CIM") "Definition Standards on
Mineral Resources and Reserves, 2004".
4. A National Instrument 43-101 Technical Report documenting the Snowden
Resource Estimate has been filed at www.sedar.com as is required by
Security Commission regulations.
5. 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.

--------------------------------------------------------------------------------
6. 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.
