International Tower Hill Mines Ltd. (TSX: ITH)(NYSE Amex:
THM)(FRANKFURT: IW9) ("ITH" or the "Company") is pleased to
announce the results from the latest 20 holes completed in its
50,000-metre Summer 2010 Livengood Exploration Program (to see Fig.
1 please click on: http://media3.marketwire.com/docs/ith107.jpg).
The infill portion of the Summer program is focused on conversion
of resources to the measured and indicated categories as well as
testing the down dip extension potential of the deposit. The
Company is currently operating seven drills at Livengood (three RC
and four core rigs).
Highlights of the ongoing 2010 work program at Livengood include:
-- Infill drilling continues to improve the definition of large higher
grade areas within the overall deposit as indicated by holes MK-RC-0410
(97.5 metres of 1.11 g/t gold) and MK-RC-0414 (134.1 metres of 1.32 g/t
gold) in the Core Zone. A higher grade area (+1 g/t gold) is being
established in the Core Zone that is approximately 200 metres wide and a
kilometre long. This expansion of the near surface higher grades
reported last month (NR10-31) is anticipated to be the focus of initial
production.
-- The Money Knob deposit at Livengood continues to expand laterally and
several of the recent drill holes indicate a significant expansion of
the Core Zone at depth.
-- The Company's pre-feasibility study is underway with ongoing
hydrological studies, surface mine facility location analysis, phase 2
metallurgical studies (optimizing milling and heap leaching recoveries),
deposit-scale geotechnical studies, and continuing environmental
baseline data collection.
Core Zone Expansion at Depth
The Company's recent Preliminary Economic Analysis (NR10-32)
shows that the potential pit would economically mine the June, 2010
estimated indicated and inferred resource to the bottom of the
existing drilling. Extending the mineralization below the current
drill depth will increase the global resource and could likely
expand the in-pit resource and increase mine life. Several drill
holes from the Core Zone reported in this news release have
returned intercepts below the previous base of drilling indicating
that the Livengood ore zone continues at depth. Significant new
intersections (Table 1) at depth include 45.7 metres at 0.9g/t gold
(333.8 to 379.5 metres down hole) in MK-RC-0410 and 44.2 metres at
0.9 g/t gold (266.7-310.9 metres), 15.2 metres at 1.0 g/t gold
(313.9-329.2 metres) and 10.7 metres at 1.0 g/t gold (333.8-344.4
metres), all in MK-RC-0411. These extensions could expand future
pit designs and increase the contained ounces proposed to be
mined.
Table 1: Significant Livengood New Intercepts(i)
(i) Intercepts are calculated using a 0.25g/t gold cutoff and a maximum of
3 metres of internal waste.

Livengood Project Highlights
-- Drilling at the project continues to expand the deposit, with the
current estimated resource only representing a snapshot in time. The
latest resource estimate (as at June 22, 2010) of 409 Mt at an average
grade of 0.83 g/t gold (10.9Moz Indicated) and 94 Mt at an average grade
of 0.79 g/t gold (2.4Moz Inferred), both at a 0.5 g/t gold cut-off
grade, makes Livengood one of the largest new gold discoveries in North
America.
-- The Core and Sunshine Zones together account for most of the higher
grade mineralization (Indicated Resources of 202 Mt at an average grade
of 1.07 g/t gold and Inferred Resources of 40 Mt at an average grade of
1.06 g/t gold, based on a cut-off grade of 0.70 g/t gold) and will form
the basis for starter pit design work.
-- Ongoing metallurgical studies are focusing on the potential use of
milling, with a flotation-gravity circuit, which has returned initial
recoveries to a concentrate of 89%, thus offering significant potential
for operational and capital cost savings. Test data for conventional
whole ore milling with a gravity-CIL system produced initial recoveries
of 76% (See NR10-19). Optimization work is ongoing for these processing
alternatives, as they have the potential to make significant positive
impact on project economics.
-- The geometry of the currently defined shallowly dipping, outcropping
deposit has a low strip ratio amenable to low cost open pit mining which
could support a high production rate and economies of scale.
-- No major permitting hurdles have been identified to date.
-- The Livengood project has a very favourable logistical location, being
situated 110 road kilometres north of Fairbanks, Alaska along the paved,
all-weather Elliott Highway, the Trans-Alaska Pipeline Corridor, and the
proposed Alaska natural gas pipeline route. The terminus of the Alaska
State power grid lies approximately 80 kilometres to the south.
-- ITH controls 100% of its approximately 145 square kilometre Livengood
land package, which is made up of fee land leased from the Alaska Mental
Health Trust, a number of smaller private mineral leases and 115 Alaska
state mining claims.
Geological Overview
The Livengood Deposit is hosted in a thrust-interleaved sequence
of Proterozoic to Palaeozoic sedimentary and volcanic rocks.
Mineralization is related to a 90 million year old (Fort Knox age)
dike swarm that cuts through the thrust stack. Primary ore controls
are a combination of favourable lithologies and crosscutting
structural zones. In areas distal to the main structural zones, the
selective development of disseminated mineralization in favourable
host rocks is the main ore control. Within the primary structural
corridors, all lithologies can be pervasively altered and
mineralized. Devonian volcanic rocks and Cretaceous dikes represent
the most favourable host lithologies and are pervasively altered
and mineralized throughout the deposit. Two dominant structural
controls are present: 1) the major shallow south-dipping faults
which host dikes and mineralization which are related to dilatant
movement on structures of the original fold-thrust architecture
during post-thrusting relaxation, and 2) steep NW trending linear
zones which focus the higher-grade mineralization which cuts across
all lithologic boundaries. The net result is broad flat-lying zones
of stratabound mineralization around more vertically continuous,
higher grade core zones with a resulting lower strip ratio for the
overall deposit and higher grade areas that could be amenable for
starter pit production.
The surface gold geochemical anomaly at Livengood covers an area
6 kilometres long by 2 kilometres wide, of which approximately half
has been explored by drilling to date. Surface exploration is
ongoing as new targets are being developed to the northeast and
west of the known deposit.

Cautionary Note Regarding Forward-Looking Statements
This press release contains forward-looking statements and
forward-looking information (collectively, "forward-looking
statements") within the meaning of applicable Canadian and US
securities legislation. All statements, other than statements of
historical fact, included herein including, without limitation,
statements regarding the anticipated content, commencement and cost
of exploration programs, anticipated exploration program results,
the discovery and delineation of mineral
deposits/resources/reserves, the potential for the expansion of the
estimated resources at Livengood, the potential for any production
at the Livengood project, the potential for higher grade
mineralization to form the basis for a starter pit component in any
production scenario, the potential low strip ratio of the Livengood
deposit being amenable for low cost open pit mining that could
support a high production rate and economies of scale, the
potential for cost savings due to the high gravity concentration
component of some of the Livengood mineralization, the completion
of a pre-feasibility study at Livengood, the potential for a
production decision to be made regarding Livengood, the potential
commencement of any development of a mine at Livengood following a
production decision, business and financing plans and business
trends, are forward-looking statements. Information concerning
mineral resource estimates and the preliminary economic analysis
thereof also may be deemed to be forward-looking statements in that
it reflects a prediction of the mineralization that would be
encountered, and the results of mining it, if a mineral deposit
were developed and mined.
Although the Company believes that such statements are
reasonable, it can give no assurance that such expectations will
prove to be correct. Forward-looking statements are typically
identified by words such as: believe, expect, anticipate, intend,
estimate, postulate and similar expressions, or are those, which,
by their nature, refer to future events. The Company cautions
investors that any forward-looking statements by the Company are
not guarantees of future results or performance, and that actual
results may differ materially from those in forward looking
statements as a result of various factors, including, but not
limited to, variations in the nature, quality and quantity of any
mineral deposits that may be located, variations in the market
price of any mineral products the Company may produce or plan to
produce, the Company's inability to obtain any necessary permits,
consents or authorizations required for its activities, the
Company's inability to produce minerals from its properties
successfully or profitably, to continue its projected growth, to
raise the necessary capital or to be fully able to implement its
business strategies, and other risks and uncertainties disclosed in
the Company's Annual Information Form filed with certain securities
commissions in Canada and the Company's annual report on Form 40-F
filed with the United States Securities and Exchange Commission
(the "SEC"), and other information released by the Company and
filed with the appropriate regulatory agencies. All of the
Company's Canadian public disclosure filings may be accessed via
www.sedar.com and its United States public disclosure filings may
be accessed via www.sec.gov, and readers are urged to review these
materials, including the technical reports filed with respect to
the Company's mineral properties.
Cautionary Note Regarding References to Resources and
Reserves
National Instrument 43 101 - Standards of Disclosure for Mineral
Projects ("NI 43-101") is a rule developed by the Canadian
Securities Administrators which establishes standards for all
public disclosure an issuer makes of scientific and technical
information concerning mineral projects. Unless otherwise
indicated, all resource estimates contained in or incorporated by
reference in this press release have been prepared in accordance
with NI 43-101 and the guidelines set out in the Canadian Institute
of Mining, Metallurgy and Petroleum (the "CIM") Standards on
Mineral Resource and Mineral Reserves, adopted by the CIM Council
on November 14, 2004 (the "CIM Standards") as they may be amended
from time to time by the CIM.
United States shareholders are cautioned that the requirements
and terminology of NI 43-101 and the CIM Standards differ
significantly from the requirements and terminology of the SEC set
forth in the SEC's Industry Guide 7 ("SEC Industry Guide 7").
Accordingly, the Company's disclosures regarding mineralization may
not be comparable to similar information disclosed by companies
subject to SEC Industry Guide 7. Without limiting the foregoing,
while the terms "mineral resources", "inferred mineral resources",
"indicated mineral resources" and "measured mineral resources" are
recognized and required by NI 43-101 and the CIM Standards, they
are not recognized by the SEC and are not permitted to be used in
documents filed with the SEC by companies subject to SEC Industry
Guide 7. Mineral resources which are not mineral reserves do not
have demonstrated economic viability, and US investors are
cautioned not to assume that all or any part of a mineral resource
will ever be converted into reserves. Further, inferred resources
have a great amount of uncertainty as to their existence and as to
whether they can be mined legally or economically. It cannot be
assumed that all or any part of the inferred resources will ever be
upgraded to a higher resource category. Under Canadian rules,
estimates of inferred mineral resources may not form the basis of a
feasibility study or prefeasibility study, except in rare cases.
The SEC normally only permits issuers to report mineralization that
does not constitute SEC Industry Guide 7 compliant "reserves" as
in-place tonnage and grade without reference to unit amounts. The
term "contained ounces" is not permitted under the rules of SEC
Industry Guide 7. In addition, the NI 43-101 and CIM Standards
definition of a "reserve" differs from the definition in SEC
Industry Guide 7. In SEC Industry Guide 7, a mineral reserve is
defined as a part of a mineral deposit which could be economically
and legally extracted or produced at the time the mineral reserve
determination is made, and a "final" or "bankable" feasibility
study is required to report reserves, the three-year historical
price is used in any reserve or cash flow analysis of designated
reserves and the primary environmental analysis or report must be
filed with the appropriate governmental authority.
This press release is not, and is not to be construed in any way
as, an offer to buy or sell securities in the United States.
