Pediment and Inmet Mining Begin Drill Testing Caborca Porphyry Targets

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 18, 2007) - Pediment Exploration (TSX VENTURE:PEZ) is pleased to report that a 2,000-metre, HQ-diameter, core drilling program has begun at its Caborca project in the Sonora-Mojave Megashear mineral belt in Sonora, Mexico. The program is funded by Inmet Mining (IMN-T) which can earn a 70% interest in the Caborca project by funding $5 million in exploration over four years. The drill program is designed to test copper-gold porphyry targets defined by IP geophysical surveys in conjunction with geological mapping and interpretation of surrounding, nearby outcrops which are indicative of porphyry mineralization. Pediment has contracted Layne de Mexico to carry out the drilling program in the Caborca project.

The drill program will consist of six holes, divided between the northern (Lista Blanca) and southern (San Juan) anomalies, respectively. Both anomalies are typified by high-chargeability, and low-magnetic responses, as defined by Pediment's geophysical programs and available government data.

Project background

The 14,000-hectare Caborca project is located south of the town of Caborca, which is the regional business and population centre for northwest Sonora State. Highways, electrical power and waterlines all cross through Pediment's holdings and railhead is within 10 km of the concessions.

During the summer of 2006, Pediment carried out a program of reconnaissance Induced Polarization (RIP) at the Caborca project, which identified two large chargeability anomalies under the valley floor to the east and south east of Lista Blanca ridge. During the summer of 2007 Inmet funded two follow up dipole-dipole IP surveys totalling 40 line kilometres conducted by Gradient Geophysics of Missoula, Montana. These programs were designed to further define the RIP anomalies and were recently completed with encouraging results. The dipole-dipole surveys confirmed the earlier RIP anomalies, indicating several large areas of high chargeability/low resistivity characteristic of buried porphyry mineralization. Pediment and Inmet have received initial interpretations from Gradient and will add this information to Pediment's website once the final report is received.

The targets are located in a broad pediment covered valley. Pediment investigated the area after the discovery that surrounding outcropping areas contained quartz-tourmaline copper veins and Pediment drilling at Lista Blanca ridge (see Pediment's news release, October 18, 2006) indicated the Lista Blanca copper-gold occurrences were hosted by a large hydrothermal breccia or elongated "breccia pipe". Quartz-tourmaline veins and large hydrothermal breccia zones are commonly found proximal to known copper-gold porphyry systems. Pediment's VP Exploration Mel Herdrick noted, "these are large anomalies and it will require a number of holes to properly investigate them. Nonetheless, there is clear potential for the project to host one or more substantial copper-gold porphyry bodies. We're gratified that our partner, Inmet Mining, concurs with our interpretation and is prepared to aggressively test it."

Drilling at Caborca will continue for the next several weeks and results will be reported once they have been received, compiled and interpreted by Pediment and Inmet.

Agreement with Inmet Mining Corp.

Pediment has an agreement with Inmet Mining Corp. to explore the Caborca project in which Pediment is the initial operator. The agreement grants Inmet an option to earn up to 70% of the Caborca copper project in return for payments of $250,000 and exploration expenditures of $5,000,000 over four years. Upon earning its 70% interest, a Joint Venture between Pediment and Inmet will be formed, with each party paying their pro rata share of ongoing expenses. Pediment may elect not to contribute and have its interest ultimately reduce to sliding scale copper and gold Net Smelter Return royalties. At current copper and gold prices the copper royalty would be 3% and the gold royalty 2%. The agreement with Inmet allows Pediment to continue to focus on project acquisition and development of its extensive gold and silver holdings while Inmet funds work towards the discovery of porphyry mineralization at Caborca. The agreement excludes the adjacent 100% owned Lista Blanca zone which was drilled by Pediment last year.

Vice President, Exploration Mel Herdrick, M.Sc. is a qualified person as defined by NI 43-101, and has approved the information contained in this release. Pediment Exploration is a well financed, aggressive exploration company with a main focus on precious metals exploration in western Mexico, and is actively exploring a series of projects in Baja California Sur and Sonora. Pediment controls ten 100% owned projects and has over $10 million in working capital.
