Pediment Exploration Drills 12.19 m of 19.87 g/t Gold Within 84.12 metres of 3.79 g/t Gold
Market Wire, July, 2007
Pediment Exploration Ltd. (TSX VENTURE: PEZ)(FRANKFURT: P5E) -
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. is pleased to report that initial assay results from the program 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), and
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(a,b) 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.
(a) This interval includes one additional sample that assayed greater than 10g/t gold by Atomic Absorption, and is thus here averaged with the rest of the samples as 10g/t gold. The fire assay, gravimetric finish result for this individual sample will be reported when received.
(b) 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 -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 2 g/t in SA97-120; the Main Zone in RC-01 begins 90 metres down hole.

calculated to dip 45 degrees to the west.
(ii) One sample that has graded greater than 10g/t Au remains to be
reassayed by gravimetric finish. A value of 10g/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 their 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 re fire-assayed with gravimetric finish.
