Geophysical Survey Identifies Six New Targets at La Poma Silver-Lead Mine
Surface sampling discovers new zone of mineralization with values up to 497 g/t silver and 1.73% copper.
Cardero Resource Corp. ("Cardero" or the "Company") -- (TSX: CDU, AMEX: CDY, Frankfurt: CR5) is pleased to announce that a recent Induced Polarization (IP) geophysical survey has identified six new high priority targets at the former high-grade La Poma Silver-Lead Mine, Salta Province, north-western Argentina. The six priority targets are not associated with exposed mineralization and were not known prior to completion of the IP survey. The results suggest that mineralization continues to a depth of at least 240 metres from surface in addition to extending the system a minimum of 500 metres to the west under younger cover sequences. The anomalies and surface mineralization remain open in all directions and suggest the significant potential for new discoveries in this new emergent silver district. The potential for discovery is confirmed by the recent discovery of a new mineralized zone, with values up to 497 g/t silver and 1.73% copper, located 3 kilometres south of La Poma.

La Poma Project Background
The La Poma Mine (Figure 1) was in production until 1964, with mine workings extending over a 2,000 metre strike length, having utilised both open pit and underground extraction methods. In early October, Cardero completed an option agreement to earn 100% of the La Poma property. Cardero's due diligence sampling returned very encouraging results: 30 characterization samples averaged 280 g/t silver, 6.05% lead, 0.31% copper, and 753 ppm zinc. Within this batch of samples, 5 samples assayed greater than 0.5 kg/t silver including 2 samples greater than 1.0 kg/t silver, up to a maximum of 1.37 kg/t. Peak lead grade is 15.8% and peak copper grade is 2.47%.
Induced Polarization (IP) Identifies 6 New Drill Targets
A total of 12 lines (13,000 m) of IP were completed in order to determine whether the known productive structures continue to depth in addition to
along strike under younger cover. Interpretation of the data has identified 6 new high priority targets, none of which are exposed at surface.
IP can successfully 'map' the presence of iron, lead and copper bearing sulphide minerals which are intimately associated with silver mineralization in the La Poma system. Intense chargeability anomalies, interpreted to represent sulphide mineralization associated with silver, are represented as red and purple colours (Figure 2).
Mineralization exposed at surface is outlined on Figure 2 as white oval shapes; the location of the six priority targets is indicated with black arrows. The geophysical anomalies remain open along strike and extend the system a minimum of 500 metres westward under younger cover rocks. The results also suggest that mineralization continues to a depth of at least 240 metres from surface.
Six priority targets have been identified as follow (Figure 2):
- Target A -- Chargeability anomaly extending 500 metres east of main mineralized exposure.
- Targets C & B -- New parallel chargeability trend to the south and extending 500 metres westward.
- Target D -- Subtle surface chargeability anomaly which becomes intense at deeper levels (not shown).
- Target E -- High chargeability anomalies under cover, interpreted to peak 100 metres below surface.
- Target F -- Chargeability anomaly extending eastward of known mineralization.

Surface Sampling Discovers New Mineralized Zone
A second phase of surface rock sampling accompanied the recently completed detailed mapping program, including 11 channel samples, 11 characterization samples and 2 float samples. The current extent of surface sampling is shown in Figure 3. Mapping and prospecting, undertaken throughout the property, discovered previously unknown mineralized outcrop, located 3 kilometres south of the former La Poma Mine. Six characterization samples were collected from vein material and weakly mineralised wallrock over a strike length of 500 metres. The best sample returned 497 g/t silver and 1.73% copper. Mean results from six samples were 106 g/t silver, 1.44% lead and 0.32% copper.
In total, Cardero has now collected 54 surface rock samples, with silver values ranging from 0.4 g/t to 1370 g/t, lead ranging from below detection to 15.45%, and copper ranging from below detection to 2.47%. Mean values from all 54 rock samples to date is 250 g/t silver, 5.73% lead, and 0.32% copper.
Surface Sampling at La Poma Mine
Results of the recent work will be used to prioritise Phase I drilling, scheduled to begin in early 2008. Drilling will test the depth extensions of mapped mineralization, below historical production drifts, together with potential strike extensions underlying volcanic cover and interpreted parallel structures not exposed at surface. Cardero is currently reviewing drill contracts for 2008 drilling.
IP is a proven geophysical technology that has, directly or indirectly, previously resulted in the discovery of significant mineralization. It is important to note that the technique is unable to differentiate between productive and non-productive mineralization and is most commonly utilized to geophysically map the hydrothermal system, structures and resistive veins undercover and at depth. Targets generated will have to be drill tested to determine the extent of any mineralization.
Qualified Person and Quality Control/Quality Assurance
EurGeol Mr. Keith J. Henderson, Cardero's Vice President-Exploration and a qualified person as defined by National Instrument 43-101, has supervised the preparation of the scientific and technical information that forms the basis for this news release.
The work program at La Poma was designed and is supervised by Keith J. Henderson, Vice President, Exploration of Cardero, who is 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 Chemex for assay. ALS Chemex'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 by Cardero personnel in order to independently assess analytical accuracy. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control.
