Vancouver — IMA Exploration (IMR-V) has defined a large induced polarization and chargeability geophysical anomaly that covers an area of about 1.6 by 1.3 km at its Navidad high grade silver property in southern Argentina.
The anomaly starts near surface in areas of exposed mineralization and in some areas extends to depths of about 300 metres. IMA states that the data shows an excellent correlation between chargeability and mapped exposures of replacement-style mineralization.
The anomalous area is almost completely obscured by soil cover and extends about a kilometre southwest of known outcropping mineralization. Chargeability anomalies are generally caused by minerals such as: base-metal sulphides, pyrite, graphite, hematite and magnetite. IMA states that only base metal sulphides have been observed on surface.
Subsequently the company geologists believe that there is a high probability this anomaly represents base-metal sulfide minerals with associated silver-lead plus or minus copper. Replacement mineralization at Navidad includes galena-matrix breccia (averaging up to 158 grams silver per tonne and 8.9% lead) as well as mineralized carapace breccia (averaging up to 111.3 ounces per ton silver, 3.7% copper, 2.1% lead).
Gravity and magnetic geophysical surveying is currently underway. Detailed sampling of mineralization at Galena and Barite Hills is now complete and will be released shortly. Once all results have been received and interpreted, IMA will then plan a substantial drill program.
IMA has about $4 million in its coffers and 44 million shares fully diluted.
