Pediment Exploration Ltd.:Drilling returns 54.9 metres of 1.6 g/t gold and 53.3 metres at 1.47 g/t gold at San Antonio.

Pediment Exploration Ltd (PEZ-V, P5E-F, PEZFF-OTCBB) is pleased to report on recently received results from continuing drill programs at its 100% owned San Antonio project in Baja California Sur, Mexico. Pediment has now completed 120 reverse circulation and 20 core holes as part of its ongoing 2007/2008 drill program at San Antonio. Results are currently awaited for 24 reverse circulation and 16 core holes. The company’s main focus has been on identifying further mineralization at the Los Planes zone, where completing infill drilling at 25- and 50-metre spacing has been combined with exploratory step-out drilling. In addition, diamond drilling at Los Planes focused on “twinning” a number of RC holes. Drilling of the historic Las Colinas resource focused on the near surface up-dip oxide portion of the zone. Highlights of the latest results are presented below followed by a table of significant intersections from the holes.

Los Planes RC Drilling

Results have been received for an additional seven holes testing the western/down-dip, eastern/up-dip and northern/on-strike areas. Please click on the link below to see a current drill plan of the Los Planes zone including locations of holes referenced in this release.

Los Planes Drill Plan

Eastern/up-dip zone

Hole PLRC-92, located 75 metres east of hole PLRC-45 on line 39,700 north was drilled with a dip of -70 degrees to the east to a total depth of 165.2 metres. PLRC-92 intersected 54.9 metres of 1.62 grams of gold per tonne. Strong oxidation is observed from 6.7 to 73.6 metres where the mixed oxide-sulphide zone begins, but continuing with dominant oxide.

Western/down-dip zone

Hole PLRC-85, located 50 metres west of hole PLRC-43 on line 39,800 north, intersected 44 metres of 1.07 grams of gold per tonne in an upper interval and 54 metres of 0.62 grams of gold per tonne on a second interval at depth. Hole PLRC-84, located 50 metres west of hole PLRC-50 on line 39,700 north intersected 34 metres of 1.09 grams of gold per tonne.

Northern/on-strike zone

Hole PLRC-87 is located 50 metres west of hole PLRC-37 on line 40,000 north, intersected 53 metres of 1.47 grams of gold per tonne. Hole PLRC-88, located 50 metres west of hole PLRC-33 on line 40,000 north intersected 45.8 metres of 1.07 grams of gold per tonne extending the zone down dip.

Las Colinas Core Drilling

Las Colinas was drilled by Echo Bay in 1996 and 1997 intersecting significant gold mineralization. The Las Colinas holes reported in this release are located on the eastern side of Las Colinas and test the up-dip continuation of the west-dipping, gold-bearing cataclasite unit close to surface. Seven diamond holes were completed for this purpose at Las Colinas of which three are reported in the present release. Results for the remaining holes will be published when available. Holes LCDD-25, 26 and 27 all intersected shallow gold mineralization. Hole 26 had the most significant intercept with 51.95 metres containing 0.96 grams of gold per tonne; including 16.0 metres of 2.11 grams of gold per tonne. These holes extend the Las Colinas zone to the east and should be additive to the historic (non 43-101 compliant) resource and the results indicate an oxide zone up to 30 meters deep.

Other Activities at San Antonio

In addition to the ongoing drill program, the company completed its second large induced-polarization geophysical program, focusing on the area north of the Los Planes gold zone to generate additional drill targets. IP geophysics was widely used by Echo Bay during its exploration programs in the late 1990’s. IP successfully generated drill targets that led to the discovery of the Las Colinas historical resource. During 2007 Pediment conducted its first IP survey which found several areas of interest and facilitated drilling that discovered the Los Planes zone. Results for the latest IP survey will be reported when received.

Core drilling at Los Planes included a number of “twin” holes drilled near existing RC holes to provide additional structural and grade information. Portions of the core were used in composite samples of oxide, mixed and sulphide material submitted to a metallurgical test facility. Results of these tests will be used to aid in economic modeling of the San Antonio project and will be reported when received. Additionally, assay results from core drilling provide confirmation of the grade and geometry of the Los Planes zone. The table below presents a comparison of the grade intervals for core hole 08PLDD-10 (the only one received to date) and nearby RC hole 07-PLRC-20. The grades of the two holes are in broad agreement indicating RC drilling presents an accurate picture of the zone. Overall, the cumulative grade X width for the intersections below totals 247 gram-metres for the RC hole and 261 gram-metres for the core hole.

Pediment is very pleased with the comparison twin drill results and continued strong drill intersections obtained at the San Antonio gold project, both at the Los Planes zone and at the Las Colinas historical resource. Drilling continues at San Antonio with additional holes planned for both zones, as well as any additional targets that may be defined by the recently-completed IP survey. Consultants independent to Pediment continue to work on an initial resource estimate for the Los Planes gold zone. They are expected to report in early June.

Mel Herdrick, VP Exploration and Director, is a Qualified Person, as defined by NI 43-101 and has approved the information in this news release. Pediment is a well funded exploration company with plans to complete exploration drill testing of Los Planes and Las Colinas zones in 2008 as well as continued exploration in both the Baja and other projects in N W Mexico.
