Pediment Exploration Ltd.: Los Planes Extended 200 Metres North; More High Grade Intercepts

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2007) -

Introduction

Pediment Exploration (TSX VENTURE:PEZ) (FRANKFURT:P5E) is pleased to report results from an additional six holes, PLRC9-13 and PLRC-18, part of the continuing 10,000-metre, reverse-circulation drill program at its 100% owned San Antonio project in Baja California Sur, Mexico. Holes PLRC-09 to 11 extended the Los Planes zone to the north. Holes PLRC-12, 13 and 18, were drilled on section N39750, which contains previously reported hole PLRC-05. All holes reported positive gold-grade intervals and three of the holes bottomed in mineralization.

Description of drill results (see the table below for details)

1. Northern Los Planes Area

PLRC-09 is located 100 metres north of hole LCDD-20, which is in turn located 50 metres east of previously reported RVC hole PLRC-07 which cut 84.12 metres of 3.79 grams of gold per tonne. Hole PLRC-09 intersected 81.38 metres at 2.02 grams of gold per tonne, including the higher-grade interval of 20.42 metres at 5.43 grams of gold per tonne. This hole bottomed in mineralization.

PLRC-11 was drilled vertically on the same pad as hole LCDD-20, 50 metres east of hole PLRC-07 and intersected three separate mineralized intervals for a cumulative total of 114 metres containing a weighed average grade of 0.80 grams of gold per tonne. The deepest intersection of 36.58 metres grading 0.98 g/t gold extended to the bottom of the hole.

PLRC-10 is the northernmost hole completed at Los Planes, 100 metres north of hole PLRC-09 or 200 metres north of the line of hole PLRC-07. Hole PLRC-10 intersected 13.72 metres of 1.41 grams of gold per tonne, thus extending mineralization 200 metres north from hole PLRC-07. See the last section for further detail on this area.

PLRC-08, collared 350 metres north of hole PLRC-07 was attempted before sufficient drill casing was delivered to site, was ended in pediment cover and will be re-drilled later.

2. Section N39750 and eastern extension of the Los Planes zone

PLRC-13 is the easternmost hole drilled on section N39750, located 100 metres east of holes PLRC-06 and PLRC-12. Hole PLRC-13 is located on the hanging wall of a postmineral, north-northwest trending fault. The fault drops the mineralized zone on its eastern side, thus creating a repetition of the west-dipping mineralized body. This hole cut 41.15 metres of 0.91 grams of gold per tonne of mostly oxide material.

PLRC-12 was drilled vertically on the same pad as PLRC-06 which was drilled with a dip of -50 degrees to the east and ended prematurely due to technical problem. PLRC-12 successfully tested the complete mineralized body intersecting 33.53 metres of 2.68 g/t gold including 7.62 metres of 8.77 g/t gold.

Hole PLRC-18 was drilled vertically on the same pad of previously reported hole PLRC-05 which was drilled with a dip of -50 degrees to the east. The latter has produced some of the best results at the Los Planes zone and the objective of hole PLRC-18 was to test the mineralization down-dip from hole PLRC-05. Hole PLRC-18 intersected 89.92 metres of 1.05 g/t gold, including a high-grade interval of 7.62 metres of 5.55 g/t gold. This hole also bottomed in mineralization.

Discussion

Holes PLRC 9 to 11 have extended the Los Planes gold zone for a further 200 metres to the north. PLRC-09 was particularly strong with 81.38 metres at 2.02 grams of gold per tonne, while hole PLRC-10 contained a narrower intercept of 13.72 metres at 1.41 grams of gold per tonne. Based on the narrow interval in hole PLRC-10 and deepening of the zone, Pediment's geologists have re-interpreted the strike of the Los Planes mineralized zone from north-south to north-northeast, dipping to the northwest. Additionally, hole PLRC-10 is interpreted to be within a small down dropped block between basin faults with northwest trends. These faults define a small Pliocene basin with sand and gravel fill. Pediment continues to explore the eastern side of this fault in order to test the oxidized gold mineralized zone to the east. The 37 holes drilled to date have not yet discovered the lateral limits of the Los Planes gold mineralized zone.

Oxide mineralized volume has continued to increase with an irregular oxidation boundary averaging nearly 100 meters depth. Many prior RC and core drill holes show good intervals of oxidized gold mineralization including PLRC-13 located east of the basin fault. The growing oxide resource will be important in developing a heap leach gold deposit.
