Goldberg finds evidence linked to a potential IOCG target at the Los Tacos prospect.

On November of 2013 Goldberg finished a sampling campaign in the prospect Los Tacos near the city of Ovalle, in which there is evidence of copper anomalies linked to low magnetic susceptibility anomalies areas and areas of alteration that could be associated with an IOCG deposit model.

The prospect Los Tacos is at 28 km to the east of the city of Ovalle in Chile, and it is hosted by 2,000 hectares of mining tenements.

The tenements showed a good prospectivity in a previous geological report performed by Goldberg in July 2011 where large areas of alteration, mainly iron oxides, chlorite, epidote, and actinolite were found on-site and then confirmed by the magnetic anomalies found in the ground magnetic survey performed by Quantec Geoscience on June 2012, in which the alteration and low magnetic anomalies show a strong control with the main fault, which is the main gorge that divides the prospect into two areas, one on in the north and the other to the south of the gorge.

Sampling was performed on the magnetic anomalies, following a mesh of 100 meters by 100 meters to confirm an association between copper anomalies and low magnetic susceptibility, as it is seen in IOCG deposits.

The sampling consisted of 419 samples of rock chips taken from outcrops near the sampling point, locations were registered by a handheld GPS, and the samples were sent for analysis to ALS for ICP-MS analysis of 51 elements at trace level (MEMS-41)

3D View of the topography at Los Tacos and the sample locations with the copper content over the magnetic susceptibility.

The result shows a copper content from 0 to 7,690 ppm, and after a process of interpolation the anomalies were selected according to its statistical distribution, the spatial distribution of the anomalies is showed in the map with orange color the high anomalies (over 70 ppm of Cu) and in red color the very high anomalies (over 200 ppm of Cu).

Geochemical anomalies of copper, in orange high anomalies over 70 ppm and in red very high anomalies, over 200 ppm.

The geological interpretation could indicate that high magnetic anomalies are linked to an intrusive that host some disseminated iron mineralization and the same intrusive and the volcanic rocks which were altered by hydrothermal fluids is showing a low magnetic susceptibility, and also is hosting the copper mineralization, as the copper anomalies are showing.

The following stage is to perform some IP (Induced Polarization) lines over the geochemical anomalies of copper to confirm the existence of electric chargeability in depth that could be associated with copper sulfurs.
