Pediment Exploration: Preliminary San Antonio Resource Estimate Totals 1.45 Million Inferred Gold Ounces

Pediment Exploration Ltd. (PEZ.V, PEZFF.BB, P5E.F) has received a preliminary mineral resource estimation for its 100% owned San Antonio gold project in Baja California Sur, Mexico. This study was completed by the firm of Derry, Michener, Booth & Wahl Consultants Ltd. (DMBW) under the supervision of Ian Thompson, P.Eng., and the resource estimate conducted under sub-contract to DMBW by David Laudrum, P.Geo. of Ashloo Consulting. This mineral resource estimate is compliant with the requirements of National Instrument policy 43-101. A report dealing with it and other aspects of the project will be filed once it is completed.

This initial estimate is based upon available results from testing completed prior to the end of 2007 and that fall within modeled parameters used in the study. Results from testing done since then, and any pertinent results from earlier testing that are currently outside the modeled parameters, will be incorporated in follow-up studies using an expanded base of results to better qualify the mineral resource. A total of more than 130 reverse circulation (RC) drill holes have been completed by Pediment to date, of which 75 were available for this study. An additional total of 36 core drill holes, including those on reconnaissance targets, have been completed by Pediment, and 17 of these were available for this study.

For Los Planes this study incorporates results defining only two sub-parallel zones constituting the main portion of the deposit. A total of five (5) RC drill holes completed by Echo Bay Mines in 1997, three (3) shallow core holes completed by Pediment in 2006, and 64 RC drill holes completed by Pediment in 2007 were used to generate the current resource estimate. Based on methodology described below, DMBW has used a 0.4 g/t cut-off grade to estimate an Inferred Mineral Resource for the Los Planes deposit of 30.58 million tonnes at an average grade of 1.32 g/t Au, for 1.30 million contained gold ounces.

For the Colinas resource estimate this study incorporates results from a total of 14 RC drill holes completed by Echo Bay Minerals in 1996-97 and five (5) core holes completed by Pediment in 2007. The estimate does not include results from surface trenches completed by either Echo Bay or Pediment, nor a small portion of the Echo Bay estimate (approximately 15%) contained by a third party concession, nor an extension of the resource to depth incorporated in a historic resource estimate for Colinas made public in 1998. DMBW has used a 0.4 g/t cut-off grade to estimate an Inferred Mineral Resource for the Las Colinas deposit of 5.62 million tonnes at an average grade of 0.83 g/t Au, for 150,000 contained gold ounces.

Pediment recently completed a series of shallow core holes to test the oxidized near surface portion of Colinas to better define the oxide portion of the resource, which currently is poorly constrained.

The mineral resource estimates were generated in Gemcom software by using data from the drill holes to generate “polylines” on east-west oriented cross sections spaced 25 metres apart, and the polylines then linked to generate a series of 3D solids (“wireframes”) of the mineralized domains. The boundaries of the zones were modeled using composite assay grades of >0.3 g/t gold and with reference to structural deformation logged in the drill holes, plus the logged base of the overburden. The selected samples were composited to regular 2 metre intervals. Measured average specific gravities of 2.6 for oxidized material and of 2.7 for sulphide material were used. Assays of >30 g/t were capped at 30 g/t gold. The methodology and conclusions of the study will be further outlined in the report being prepared by DMBW.

Pediment is currently awaiting the results for preliminary metallurgical testing from nine (9) composite samples of RC material that have been sent to SGS Mineral Services in Durango Mexico. These results will be followed up by metallurgical sampling using a core drill rig. In addition to completing sufficient testing to better qualify the Los Planes and Las Colinas resources in order to generate a Preliminary Economic Assessment of the project, the company is continuing its program of reconnaissance exploration and targeting along the San Antonio Gold trend that is still largely untested within Pediment’s holdings.

Mel Herdrick, the company’s VP Exploration, states “The work to date has been very successful in establishing this preliminary resource estimate within a year of our discovery testing. We look forward to both expansion potential in our current testing, and to further testing along the balance of the trend. Future drilling, in addition to both expanding and refining the known mineralized bodies, will test other target areas identified by the latest IP survey. The company expects to release additional drill results from the project soon.”

Mel Herdrick, a Qualified Person as defined NI 43-101, has reviewed and approved this release.

Pediment Exploration is a precious metals exploration and development company working in western Mexico on two key projects, La Colorada in Sonora and The San Antonio Gold Project in Baja California Sur, as well as reconnaissance programs. The company is well capitalized with more than $20 Million in the bank and no debt.
