Reported drill intercepts are based on apparent rather than true thickness as there is insufficient data with respect to the shape of the mineralization to calculate absolute true thickness.PHASE I DRILL TESTINGPhase I exploration at the Sheini Hills Iron project has been completed. The program targeted two main types of potential iron ore, ironstone ridges and surface ferricretes, both being haematite-dominated with negligible magnetite content.Ironstone Ridges have been tested with 9192.4 metres of diamond drilling. A total of 67 diamond drill holes have been completed to date, with results received for the first 34 drill holes (58 diamond drill holes were sent in for assay, 9 holes were drilled for geological interpretation and metallurgical testing).In Phase I, ironstone ridges were drilled over a strike length of 9 kilometres north-south and along section lines averaging approximately 600 metres east-west. Aggregate apparent ironstone thicknesses range from 3.8 metres in SCD032 to 278 metres in SCD039. Outcropping ironstones over an additional 24 kilometres of strike length have been targeted for future drill-testing.The Ironstone ridges are composed of two potential ore-types. Higher grade thinly banded ironstones are considered to be primary Rapitan-type ironstones, although an epigenetic origin cannot be entirely ruled out. Associated diamictites, sediments of probable glacial origin, are thought to be epigenetic and partially replaced by haematite.Surface Ferricrete/Detrital Deposits were tested with 1923 metres of reverse circulation drilling.Detrital iron deposits are found where weathering has eroded bedded iron deposits and deposited ironstone fragments in natural traps formed by topography. Some deposits are loose gravels while others are naturally cemented (hematite conglomerate) and both types are found peripheral to the Sheini Hills ironstone ridges. When rock units break down under the weathering process they are often affected by circulating groundwater and under appropriate conditions typically form hard indurated zones such as ferricrete and laterite.The quality of the potential iron ore in these deposits depends on the grade and quality of the iron particles making up the clasts in the conglomerate. At Sheini, the ferricrete tends to be composed primarily of the higher-grade, banded-type ironstone, rather than the lower-grade diamictite, which is easily broken down by weathering processes.RESOURCE ESTIMATE UNDERWAYNow that the Phase I exploration program at Sheini Hills has been completed, SRK Consulting has been retained to complete an updated 43-101 report, including a maiden resource estimate. Cardero anticipates completion of the report in Q4 2012.PROJECT RATIONALEIronstone ridges are being targeted for potential open pit mining. The ironstones being drilled are generally in excess of 30 metres in thickness and apparent thicknesses locally reach greater than 250 metres from surface.Ferricrete/Detrital Deposits are surface deposits situated on the fringes of the ironstone ridges. They are typically in the range of 5 to 15 metres in thickness. The attraction of deposits of this type is that they would not require normal open pit mine development, since the mineralization is at surface and of limited thickness (generally less than 15 metres). Instead, the deposits, if mined, could be extracted using equipment such as open bowl scrapers, which can remove softer overburden material without the need for blasting. This type of machinery is frequently utilized at civil engineering projects but is also used to clear overburden in mining operations. Efficient removal of the mineralization from these deposits in this way could provide significant operational savings. Iron grades in the Detrital Deposits are typically lower than grades in primary ironstone because the deposits are semi-consolidated and contain a portion of soil and non-iron related material. This is not considered to be a disadvantage since those materials should be easily removed during beneficiation. Removing surface mineralization in this way results in a zero strip ratio. If the Sheini Project should be advanced to mining in the future (of which there can be no certainty), the surface Detrital Deposits could potentially be mined first, while major open pit development and pre-stripping is taking place on the ironstone ridges.QUALIFIED PERSONEurGeol Keith Henderson, PGeo, Cardero's Executive Vice President and a qualified person as defined by National Instrument 43-101, has reviewed the scientific and technical information that forms the basis for portions of this news release, and has approved the disclosure herein. Mr. Henderson is not independent of the Company, as he is an officer and shareholder.QA/QCThe work program at Sheini is supervised by Christopher White (Cardero Resource Corp.) and Dr. Karel Maly (Aurum Exploration Limited), who together are responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project rigorously collect and track samples which are then security sealed and shipped to ALS Laboratories, Kumasi, Ghana, for sample preparation, and onward to OMAC Laboratories (an ALS Group company), Ireland, for analysis. OMAC's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Blind certified reference material is inserted at regular intervals into the sample sequence in order to independently assess analytical accuracy.ABOUT CARDERO RESOURCE CORP.The common shares of the Company are currently listed on the Toronto Stock Exchange (symbol CDU), the NYSE-MKT (symbol CDY) and the Frankfurt Stock Exchange (symbol CR5).
