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.
1. 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.
2. 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.

** 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.

Mr. Gary Freeman reports
PEDIMENT AND INMET MINING BEGIN DRILL TESTING CABORCA PORPHYRY TARGETS
Pediment Exploration Ltd. has begun a 2,000-metre, HQ-diameter, core drilling program at its Caborca project in the Sonora-Mojave Megashear mineral belt in Sonora, Mexico. The program is financed by Inmet Mining Corp., which can earn a 70-per-cent interest in the Caborca project by financing $5-million in exploration over four years. The drill program is designed to test copper-gold porphyry targets defined by induced polarization (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 kilometres 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 southeast of Lista Blanca ridge. During the summer of 2007, Inmet financed two follow-up dipole-dipole IP surveys totalling 40 line kilometres conducted by Gradient Geophysics of Missoula, Mont. 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, as reported in Stockwatch on Oct. 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 vice-president of 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-per-cent of the Caborca copper project in return for payments of $250,000 and exploration expenditures of $5-million over four years. Upon earning its 70-per-cent interest, a joint venture between Pediment and Inmet will be formed, with each party paying their pro rata share of continuing 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 per cent and the gold royalty 2 per cent. The agreement with Inmet allows Pediment to continue to focus on project acquisition and development of its extensive gold and silver holdings while Inmet finances work toward the discovery of porphyry mineralization at Caborca. The agreement excludes the adjacent 100-per-cent-owned Lista Blanca zone which was drilled by Pediment last year.

Mr. Gary Freeman reports
PHASE ONE DRILL TESTING AND ON-GOING TARGETING UNDERWAY AT DANIEL
Pediment Exploration Ltd.'s initial drill test of the Daniel gold project is under way. Daniel is 40 kilometres northwest of Caborca in northwestern Sonora state, on good secondary road access that is within 10 km of a paved highway and power corridor. The project is located in the Mojave-Sonora Megashear gold trend and about 45 km on trend to the southeast of La Herradura gold mine, operated by Industrias Penoles SAB de CV in joint venture with Newmont Gold Corp., which is the region's archetypical large-scale gold resource below pediment cover.
Geological mapping and trench sampling at Daniel have established a trend of at least four km length in which gold is associated with quartz-carbonate vein and stockwork zones with minor sulphide minerals. This trend is along the sheared contact between rhyolitic and overlying dacitic volcanic units. Most of the gold anomaly and showings are within the rhyolite, but some values including the project high from outcrop sampling of 101 grams per tonne (g/t) gold are located within the overlying dacitic units. There is also an area of mineralization dubbed Coyote located near the contact between the rhyolite and underlying sedimentary rock (primarily sandstone and conglomerate) to the west.
Gold was emplaced by hydrothermal fluids flow focused by northeasterly dipping thrust faults into open spaces created by shattering of brittle rock during regional-scale deformation. This drill program will include testing the possibility that the overlying dacite was more impervious to the mineralizing fluids then the rhyolite so that "ponding" of the fluids took place along this contact area. Ponding of this type has enhanced both gold grade and deposit scale in a number of gold districts. The primary target for the program is discovery of a Megashear-style bulk tonnage grade gold deposit that would allow mining operations with low operating costs.
The initial drill phase will be a 5,000-metre program of 30 to 40 large diameter reverse circulation holes, focused on testing broad areas of gold anomaly in trench sampling at the Coronela and on-trend Sierrita showings. Several holes will also test the Coyote target and La Morita target that is currently the northern most extent of the main trend in Pediment ground. As announced in late December, Pediment has staked the new Daniel 7 concession that covers the on-trend potential to the north of La Morita. The company will be conducting initial targeting programs there concurrently with this initial drill phase.
The links below to Pediment's website located a geology map of the Daniel project with sample results and the locations of the different showings, and a hypothetical east-west cross-section though the Coronela and Coyote zones based on the results of the surface mapping.

Vice-president of exploration Mel Herdrick comments: "Broad sections of anomalous gold around higher grade surface showings at Daniel is the ideal setting to begin our drill testing of the company's Megashear gold portfolio. Details about these systems from the surface work at Daniel are already being applied in targeting programs elsewhere in this belt. The Daniel program represents Pediment's corporate philosophy of using modern exploration theory and techniques that allow us to simultaneously explore a number of projects with multimillion-ounce discovery potential and thereby maximize leverage for our shareholders."
