INTERNATIONAL ENEXCO LTD. REPORTS UPDATED PRE-FEASIBILITY STUDY FOR THE CONTACT COPPER PROJECT, NEVADA

Vancouver, B.C. - June 2, 2010. Arnold Armstrong, President and CEO of International Enexco Ltd. (TSXV - IEC) (the "Company") announced today that the Company has received an Update to the 2009 Pre-Feasibility Study (PFS) for its 100%-owned Contact Copper Project, Nevada, in accordance with Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101").

The Update and 2009 PFS are NI 43-101 compliant studies prepared for Enexco by Gustavson Associates, LLC of Lakewood, Colorado, an independent engineering consulting group. The Update is based on addition of 2009 drilling results, and includes re-interpolation of the resource model and optimization of the pit design using parameters from the PFS. The changes result in a 161% increase in mineable copper and improvements to the cash flow model of 20.2% IRR, up from 13.2% in the PFS, and a net present value (NPV) at 10% discount rate of $44.5 million, up from $9.7 million in the PFS.  

The Updated Mineral Resource at Contact now stands at 711.8 million pounds of copper (298.3 million pounds Measured and 413.4 million pounds Indicated) (135.2 million tons at 0.263% Cu), with an Inferred Resource of 291 million pounds of copper (53.4 million tons at 0.272% Cu), based on a 0.10% Cu cut-off grade.  The Update includes an additional 20,745 feet of core that was completed in 20 drill holes, along with the re-interpretation of geologic contacts, and revised criteria for grade interpolation using an ID-2 model and the classification of resources.

Mineral Resource Estimate reported at 0.10% Cu cut-off.

The copper reserves are now estimated at 27.0 million tons at 0.30% Cu proven and 27.1 million tons at 0.28% Cu probable, totaling 54.1 million tons of 0.28% Cu or 317 million pounds of Cu in proven and probable reserves. No inferred resources were used in either the production schedule or economic analysis. The Updated reserves represent a 161% increase in copper reserves, up from 33.6 million tons of 0.29% Cu or 197 million pounds of Cu proven and probable reserves in the 2009 PFS.

Mineral Reserve Estimate reported at 0.10% Cu cut-off.

For the Updated PFS, Gustavson developed a 9 year mine plan and production schedule based on an open pit mine producing 5.6 million tons of ore per year at an overall 2.9:1 strip ratio. Copper recovery is unchanged from the PFS net overall recovery of 76%.  Overall production is projected at 241 million pounds of copper, supporting 25 million pounds per year of cathode copper from heap leaching and solvent extraction-electrowinning (SX/EW), at an average cash cost projected at $0.93/lb.  The initial capital costs are now estimated at $88 million, including a contingency of 20%.  Based on the PFS copper price of $2.25/lb, the project after-tax net present value (NPV) at 10% discount rate is forecast at $44.5 million, up from $9.7 million, and the  internal rate of return (IRR) is 20.2%, up from 13.2% in the PFS.

In light of the results, Arnold Armstrong, President & CEO, commented today that:

"The Updated PFS is another milestone for the Contact Project. The global economy continues to show demand for copper. We believe we have a viable project in Contact, and still have room for further improvement. With the new results, we are evaluating how to best proceed, whether through additional drilling or by permitting and engineering studies that will lead us more directly to production."

A copy of the full Updated PFS Technical Report will be filed on the SEDAR website within 45 days.
