Vancouver, BC � September 15, 2008  INTERNATIONAL BARYTEX RESOURCES LTD. (�the Company�) (TSX-V: IBX) on behalf of its subsidiary, East China Capital Holdings Ltd., has delivered a Feasibility Study on the Shituru Copper Project to La Generale des Carrieres et des Mines (Gecamines), its partner in the project, in accordance with the requirements of its joint venture agreement (Mining Contract).

The Feasibility Study proposes developing an open pit, ore processing and electrowinning facility with an annual production capacity of 38,000 tonnes of LME grade cathode copper.  The lead consultant for the Feasibility Study was Bateman Minerals and Metals with the Mineral Resource and Mineral Reserve estimates prepared by SRK Consulting; both companies are Johannesburg based.

The project scope is largely unchanged from the Preliminary Assessment disclosed in January 2008 with the exception that the annual ore processing rate has been reduced to 900,000 tonnes per year.  The decision to design on a lower throughput was based on the Feasibility Study production schedule having higher grades thereby allowing copper production to be maintained while processing ore at slower rates.

A Summary of the Feasibility Study results is provided below:

Mineral Resource ^1,2,3
At a 1.0% Copper Cut-off Grade

1. Includes the Mineral Reserve.  Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability 
2. As of Aug 31,2008
3. See footnote at the end of this news release

The Mineral Resource was estimated by SRK Consulting of Johannesburg using 3-D computer modeling and geostatistical estimation techniques. 

Mineral Reserve ⁴

4. As of August 31, 2008

The Mineral Reserve was determined by SRK Consulting utilizing computerized open pit optimization techniques with estimated operating costs, results from a geo-technical drilling program, and metallurgical test work carried out over the last two years being inputs to the work.

The project assumes initial construction of a Whole-Ore-Leach (�WOL�) process plant and a Solvent Extraction � Electrowinning (�SX-EW�) refinery to produce LME grade cathode copper.  The Feasibility Study estimates 80% of the ore processed is amenable to Whole-Ore-Leaching.  This ore type occurs mainly in the upper parts of the deposit.  It has better grade, better metallurgical recovery and lower operating costs than the remainder of the deposit.  This results in lower production costs and higher copper production in the early years of the operation compared to the Life-of-Mine average.

Using a strategy similar to the January 2008 Preliminary Assessment, lower grade, higher operating cost, high carbonate ore is stockpiled until Year 5 of operation.  A flotation plant is to be constructed to process this ore in Year 5.  High carbonate ore would then represent 40% of the ore processed until the end-of-mine life.  The flotation plant would produce an oxide copper concentrate which would then be fed into the leaching circuit and SX-EW refinery to produce cathode copper.  The flotation process allows high acid consuming (high carbonate) material to be discarded ahead of the acid leaching process and substantially reduces the processing costs for this ore type.

The initial capital cost of USD338million for the project compares to USD228million estimated in the Preliminary Assessment.  This increase reflects a general increase in material and supply costs as well as labour costs currently being experienced in the DRC.

Leo King, President says, � Delivery of the Shituru Feasibility Study to our partner Gecamines is a significant milestone for the Shituru project.  As noted in earlier news releases over the course of completing the Feasibility Study a number of areas that would benefit from further optimization have been identified.  We have started work on some of these areas and intend to pursue others following our review of the Feasibility Study.  We look forward to reporting on this optimization work as results become available.�
