PBX Files Revised 43-101 Technical Report
on its Copaquire molybdenum – rhenium - copper Property.
June 23, 2009
International PBX Ventures Ltd. (PBX:TSX.V) is pleased to report it has submitted a revised NI 43-101 technical report for its 100% owned Copaquire molybdenum – rhenium - copper porphyry project, Chile. The revised report is a revision of a technical report dated April 7, 2009 and expanded on the company’s news release of January 12, 2009 which updated the current status of the mineral resources of the Cerro Moly molybdenum-rhenium-copper deposit. The revision was requested by the British Columbia Securities Commission (the "BCSC"), the securities regulatory authority in the Province of British Columbia, Canada who upon conducting a review of the report identified a number of deficiencies and requested the company to file a revised technical report.
The preparation of the April 7, 2009 technical report was carried out by Mr. Gino A. Zandonai. However Mr. Zandonai is not a member of a foreign professional association listed in Appendix A to NI 43-101 and therefore is not a qualified person and cannot co-author the technical report or take responsibility for the Company’s disclosure of mineral resources.
The May 10, 2009 revised report is authored by Mr. Eduardo R. Videla, MAusIMM a consulting geologist and a Qualified Person under NI 43-101. Mr. Videla has over 15 years experience calculating mineral resource estimations on a wide variety of porphyry deposits around the world, many similar to the Copaquire deposit.
Mr. Videla’s May 10, 2009 revised report uses a base case cutoff grade estimation of 0.03% Mo as a more reasonable prospect for economic recovery. The 0.03% Mo cutoff grade supersedes the 0.02% Mo cutoff grade used in Mr. Zandonai’s April 7, 2009 technical report as well as the 0.02% Mo cutoff grade stated in the Company’s April 20, 2009 news release.
No change has been made to the resource table in the April 7, 2009 report.

These mineral resource estimates were prepared under the supervision of Mr. Eduardo R. Videla, MAusIMM an independent Qualified Person under NI 43-101. Mr. Videla has reviewed and approved the technical information in this news release.
The geological resources have been estimated using Ordinary Kriging (OK) geostatistical method. Resource estimation was constrained by a 3-dimensional solid model developed from geological and analytical data. Block size used was 40mx20mx20m and grade estimation was carried out by the ordinary kriging using 2 metre downhole drill composites.
Drill samples for analysis averaged 2 metres in length of split NTW and HQ-size core except for 9 holes from the 2005 program which were sampled on 3 metre intervals. The 2007/08 drill program utilized modern QA/QC practices involving insertion and monitoring of reference standards, duplicates and blanks. 11,456 samples for Mo, 11,439 samples for Cu and Mo and 6,454 samples for Re were analyzed for the resource calculations. All analytical work was conducted by ALS Patagonia Laboratories, Chile, an ISO 9001 registered facility, located in Coquimbo, Chile. Samples for check assays were submitted to Chemex, an ISO 9001 registered facility, located in Vancouver.
