Mr. Gary Freeman reports

PEDIMENT EXPLORATION DRILLS 12.19 M OF 19.87 G/T GOLD WITHIN 84.12 METRES OF 3.79 G/T GOLD.

After having finished the first seven drill holes of its planned 10,000-metre reverse circulation program at the Los Planes zone in the San Antonio project, Baja California Sur, Pediment Exploration Ltd. has provided its initial assay results from the program, which have significantly increased mineralized volume at the project. Results have been received from four drill holes, three of which (PLRC-01, PLRC-05 and PLRC-07) fully penetrated the known thickness of Los Planes system, which is located north of the Las Colinas historic resource. Hole PLRC-06 was stopped at 62 metres and short of intersecting its target due to difficult ground conditions. Another drill hole in this area is planned with vertical orientation.

Summarizing the combined intercepts of each drill hole received below are as follows:


PLRC-07 -- 84.12 metres of 3.79 grams of gold per tonne;
PLRC-05 -- 100.58 metres of 1.60 grams of gold per tonne (near true width);
PLRC-01 -- 83.82 metres of 1.47 grams of gold per tonne (near true width).

Brief description of drill results

Drill hole PLRC-07 is located 50 metres west of previously reported core hole LCDD-20 and was drilled vertically. The hole has returned 84.12 metres of 3.79 (1, 2) grams per tonne gold, which includes 12.19 metres of 19.87 grams per tonne gold. Since the mineralized zone has a calculated dip of 45 degrees to the west, the true thickness of the zone is calculated at approximately 59 metres in this section. Hole PLRC-07 is the most northerly test of the Los Planes shear system to date.


This interval includes one additional sample that assayed more than 10 g/t gold by atomic absorption, and is thus here averaged with the rest of the samples as 10 g/t gold. The fire assay, gravimetric finish result for this individual sample will be reported when received.
Grades were not cut for calculating average grades in the interval.

Drill hole PLRC-05 is located 100 metres south, along trend from hole PLRC-07 and between previously reported core holes LCDD-18 and LCDD-19. Hole PLRC-05 has returned 18.29 metres of 2.28 grams per tonne gold in an Upper zone and two further intersections of 15.24 metres of 2.0 grams per tonne gold and 62.48 metres of 1.357 grams per tonne gold, which include higher grade sections of 3.05 m of 7.27 g/t gold, and of 13.72 m of 4.87 g/t, respectively. In contrast with hole PLRC-07, this hole was drilled at a minus-50-degree angle to the east and the length of its intersections are near true thickness of the zone.

Drill hole PLRC-01 is located 100 metres south, from PLRC-05 and 100 metres east from Echo Bay's reverse circulation hole SA97-120. Hole PLRC-01 returned 24.38 metres of 1.20 grams per tonne gold in the Upper zone, and 59.44 metres of 1.58 grams per tonne gold in the Main zone. The Upper zone in RC-01 begins 18.3 metres down hole and is the oxidized portion of a zone that included 16.5 m of two g/t in SA97-120; the Main zone in RC-01 begins 90 metres down hole.

* Not true width. Hole was drilled vertically and mineralized zone is calculated to
dip 45 degrees to the west.

** One sample that has graded more than 10 g/t Au remains to be reassayed by gravimetric
finish. A value of 10 g/t Au has been used temporarily to calculate the interval.

Assay results for RC holes PLRC-02, 03 and 04 are pending. Sampling of the reverse circulation drill holes is done by collecting sections of 1.52 metres length and splitting each on site. A split from each sample is shipped to the ALS Chemex preparatory facility in Hermosillo, Sonora, Mexico, and is then ground to a fraction to be sent to its laboratory facility where it is analyzed for gold and several other elements by induced coupled spectrometer. Gold is analyzed by fire assay with atomic absorption finish and any results over 10 g/t gold are refire assayed with gravimetric finish.

All of the reported RC holes except PLRC-07 were drilled from west to east at an angle of minus 50 degrees. In order to better penetrate the full thickness of the zone, PLRC-07 was drilled vertically. Subsequent drilling at Los Planes will continue to be mainly vertical to avoid drilling problems. The Los Planes zone trends approximately due north to south, and dips to the west at 40 degrees to 45 degrees. The northerly portion of Los Planes zone tested by Pediment is now recognized in general as an approximately 100-metre-thick shear zone within which occur higher grade sections where gold is associated with sulphide mineralization or its oxidized equivalent. The Los Planes zone remains open and untested to the north, south, and both the eastern (up dip) and western (down dip) boundaries of the system are still to be determined.

Based on limited testing by prior operators plus work to date by Pediment, the Los Planes mineralization extends for at least 600 metres of strike length. The historic Las Colinas gold deposit (340,000 ounces of gold, historical resource) is located 500 metres farther south of Los Planes, within an offset portion of the same north-south-trending San Antonio structural corridor that contains both zones.

The company has staked a 14-kilometre-long portion of the San Antonio trend extending from Las Colinas deposit northward, and will test other targets along this trend generated by its geophysical and geochemical surveys of pediment cover to the north of Los Planes. There is no history of gold exploration in this area. The San Antonio project is located adjacent to the mining town of San Antonio and 40 km southeast of the port city of La Paz that is serviced by daily vehicle and passenger ferries and by passenger aircraft. A paved road, power line and communication corridors run through the project.

Review of history and potential of the San Antonio project

The Los Planes deposit area was selected for planned drill testing based on compilation of limited prior drilling by Echo Bay, current geological investigations coupled with an IP ground geophysical survey, and more than 3,000 sample grid soil program. Echo Bay drill data from 1995 to 1997 were recently purchased from Kinross Gold Corp. covering both Las Colinas and Los Planes areas.

The Las Colinas resource mineralization was estimated by Echo Bay to be 10.599 million tons containing 348,000 ounces of gold.* Pediment recently added five more core drill holes to Las Colinas with somewhat higher grade results than the stated average for the deposit. Echo Bay did some sulphide metallurgical work on Las Colinas with favourable results through Hazen Research in Colorado.

* A qualified person, as defined by NI 43-101, has not done sufficient work to classify the historical estimate as current mineral resources, the issuer is not treating the historical estimate as current mineral resources and the historical estimate should not be relied upon.

Core drilling at Los Planes was initiated in May, 2007, completing four core drill holes. This drilling north of prior holes revealed a deeper zone of oxide mineralization with thicker intercepts than Echo Bay found. Problems in drill penetration led to changing to RVC drilling. Seven RVC drill holes have been completed, which are partially reported here, that now show a much thicker zone with higher gold grade in the shear zone.

Drill intersections at the south end begin approximately 600 metres south of RVC 7 where two intervals total 7.5 m of 1.08 grams, then 400 m south of RVC 7 with two drill holes intersected having 15 metres combined of 1.32 g/t and 16.5 combined with 1.06 g/t. All sections located farther north have higher grades, and more width in drilling by both Pediment and Echo Bay.

The company has built an exploration model assisted by various geological sources including Arizona State University structural expert Dr. Steven Reynolds and graduate student Josh Coyan, and independent consultant Stan Keith. The main low-angle shear zones are hosts to deep mesothermal gold mineralization of the "intrusion-related" type connected to peraluminous intrusions. Large zones of this type of mineralization are thought to have long trends and similar related parallel zones. Adjacent zones called Fandango, La Virgin and Colpa are concluded to have potential based on anomalous soil geochemical values, geophysical surveys, and scout drilling in the La Colpa northern area. These parallel anomalous shear zones are being investigated for gold potential, and may receive limited drill testing later this year. Drilling at San Antonio continues and results will be released on a regular basis.
