Eloro Resources Ltd. announced that the majority of the Iska Iska Project, located in the Potosi Department, Southwestern Bolivia, has now been covered by an expanded induced polarization/resistivity (IP/Res) survey.
Green solids indicate high grade mineralized zones where the silver equivalent grade is greater than 50 g Ag eq/t. These high-grade areas coincide very closely with high chargeability (> 20 mV/V), confirming the correlation of grade with borehole IP between drill holes inside the MRE pit.

Using a deep-penetrating array of 50 m and offset 100 m dipoles, east-west lines have been completed every 200 m across and southeast of the Santa Barbara mineral resource, obtaining a depth of investigation approaching 400 m. It is now possible to image mineralization at elevations below 3600 m in an extension beyond the open southeast side of the pit that defines the initial mineral resource estimate (MRE), thanks to the new array and lower surface elevations.
In this survey, peaks in the grade of the polymetallic Ag-Zn-Pb mineralization expressed as silver equivalent coincide with chargeability highs across the volume already drilled for the Santa Barbara MRE.
We have had great success with our borehole IP/Res program correlating mineralization between the drillholes, but the surface IP/Res provides a 3-dimensional view well beyond where we have drill hole coverage. The new chargeability anomaly, extending southeastward from the open pit that defines the MRE, adds at least an additional 600 m of potential strike length to the major mineralized structural corridor that is up to 800 m wide for an overall strike length of at least 2 km.

Dr. Bill Pearson adds, “This new target area has not been drilled. In addition, the chargeability anomaly southeast of the pit is very strong, suggesting that it is a prime target for outlining additional higher-grade polymetallic mineralization.”
