Cardero Resource Corp. (TSX:CDU,NYSE:CDY,FWB:CR5) announced magnetic data has identified ironstone drill targets, all of which are supported by outcropping ironstones identified during recent follow-up geological mapping.
As quoted in the press release:
Mineralization in the ironstone is predominantly haematite and as such is only weakly magnetic. At these latitudes, close to the equator, magnetic anomalies are negative and appear as low green to blue colours.
In the Phase I drill area, topography is pronounced, varying from 150 metre plains to 465 metre ridges (Figures 2 and 4). In these areas ironstones are well exposed and were easily mapped and targeted for drilling. In the southern area of future drill targets (Figures 2 and 3), topography is much more subdued with less pronounced ridges and generally less ironstone outcrop.
