July 27, 2010, Scottsdale, Arizona - International Minerals Corporation
(Toronto and Swiss stock exchanges - IMZ or the Company) reports new
high-grade drill results from the Angela Vein at the 51%-owned Inmaculada
gold-silver project, located approximately 25km southwest of IMZs
40%-owned Pallancata silver mine. The current drill campaign is designed to
move inferred resources into the indicated and measured categories, as a
requisite to completion of a feasibility study in 2011.

Several high-grade intercepts (estimated true widths) are reported in the
latest drill results, including 4.0 meters (m) at an average grade of
33.6 grams per tonne (g/t) gold and 789 g/t silver and 4.0m at an average
grade of 24.2 g/t gold and 706 g/t silver.

Assay results for all 34 core drill holes totaling 11,702 m (Inma 135-168)
are summarized in Appendix 1 and shown on the long section in Appendix 2.
Assay results for 47 core drill holes totaling 9.499m (Inma 88-134) were
previously reported in a May 4, 2010 news release.

Highlights of drill results (in sequential drill hole order) from the 34
drill holes, representing estimated true widths and average uncut grades,
include:

2.1m at 17.4 g/t gold and 623 g/t silver (Inma-139)
4.0m at 24.2 g/t gold and 706 g/t silver (Inma-143)
6.0m at 15.5 g/t gold and 617 g/t silver (Inma-149)
10.5m at 6.3 g/t gold and 232 g/t silver (Inma-155)
10.0m at 7.7 g/t gold and 186 g/t silver (Inma-158)
5.0m at 19.9 g/t gold and 285 g/t silver (Inma-132)
4.0m at 33.6 g/t gold and 789 g/t silver (Inma-159)
8.5m at 8.1 g/t gold and 178 g/t silver (Inma-160)
4.0m at 5.1 g/t gold and 375 g/t silver (Inma-161)
6.0m at 11.6 g/t gold and 505 g/t silver (Inma-162)
3.2m at 19.9 g/t gold and 445 g/t silver (Inma-168)

Mineralization in the Angela Vein currently extends over a strike length of
more than 1,900 m with a vertical extent of up to 300m and remains open
along strike to the northeast. The Angela Vein is one of several
significant vein systems recognized at the Inmaculada Project, most of
which are relatively under-explored.

In February 2010, an independent National Instrument (NI) 43-101
compliant mineral resource estimate on the Angela Vein (based at that time
on approximately 25,000m of drilling in 84 core holes over 1,500m of
mineralized strike length) reported both indicated and inferred resources
for the Angela vein at a 3 g/t gold-equivalent cut-off grade (assuming a
60:1 silver to gold ratio) as follows:

Indicated Resources: 1,238,000 Tonnes at 3.9 g/t gold and 122 g/t silver
containing approximately 154,000 ounces of gold and 4.9 million ounces of
silver (100% project basis)

Inferred Resources: 4,686,000 Tonnes at 3.4 g/t gold and 147 g/t silver
containing approximately 512,000 ounces of gold and 22.1 million ounces of
silver (100% project basis)

An updated mineral resource estimate for the Angela Vein (including the
results for an additional 52 drill holes totaling 15,650m, up to and
including drill hole INMA 139) will be announced by IMZ by the end of the
third calendar quarter of 2010. A significant increase in tonnes and
contained gold and silver ounces is expected.

Feasibility Study Update

Three core drill rigs have been operating on-site at Inmaculada for several
months with the intention of expanding and upgrading the resource estimate
to support completion of a feasibility study, including a mineral reserve
estimate, by the end of 2011. The current infill drill program is expected
to be completed by the end of August.

Metallurgical testwork is ongoing. Preliminary results to date suggest that
the Inmaculada mineralization could be treatable by conventional processing
techniques with good metal recoveries.

Property Status

IMZ currently owns a 51% interest in Inmaculada (and is the project
operator) with Hochschild Mining plc (Hochschild) owning the remaining
49% interest.

IMZ can earn and acquire an additional 19% interest (total 70%) by
completing (at its sole cost) a feasibility study by September 2013 and by
issuing 200,000 common shares to Hochschild over a 5-year period,
commencing February 2011.

General

Sample preparation and analytical work for the Inmaculada drilling program
were carried out by SGS Mineral Services in Lima, Peru using
industry-standard sampling practices and analytical methods for silver and
gold. As part of IMZs QA/QC protocol, standard samples and blanks were
inserted into the sample processing stream at a rate of one per 10 samples.
Duplicate and alternate laboratory check samples also form part of this
sampling protocol. The technical disclosure including drill results in this
news release were reviewed by IMZs Qualified Person, Exploration Manager,
Mark Cannuli.

The previous Angela Vein mineral resource estimate was classified as
indicated and inferred in accordance with CIM guidelines, as required by NI
43-101, by FSS Canadas Qualified Person R. Mohan Srivastava (P.Geo.). The
estimate has an effective date of February 3, 2010.
