Introduction
The Isabelita project is located in the far north of Patagonia, in central Argentina.
The mining properties, 100% owned by Tamar Mining SA, cover a total of 48,400 hectares distributed over 5 mining properties with great potential for exploration and discovery of possible mineral deposits. Old mining works are distributed throughout these properties.
The first two mining claims cover a leached copper anomaly associated with sericitic alteration.
This copper associated with a quartz-sericite-magnetite alteration extends along 8 km through quartzite outcrops fractured by intense veining.
The main sector of the strike presents copper anomalies in an area of 1.5 x 0.5 km, with rock sample values between 1000 and 4000 ppm Cu and 25 to 80 ppm Mo, within a broader copper anomaly whose surface limits have not been fully defined.
The area presents a strong structural control, which facilitates the circulation of hydrothermal fluids carrying elements of economic interest throughout the Isabelita project, increasing the possibilities of defining new exploration targets.
Exploration and mineralization
Disseminated copper mineralization is located in a 3 km x 1 km core zone , where rock chip geochemical samples commonly exceed 500 ppm Cu . Within this area, a 1.5 km x 0.5 km core shows values in excess of 1000 ppm Cu.
Sericitic alteration is widely distributed in the quartzite, while chloritic and potassic alteration are recognized in specific sectors.
Mineralization is structurally controlled by microbreccias, breccias and quartz veins.
Minor gold mineralization associated with disseminated pyrite, high arsenic and total iron values has been identified on the southern margin of the quartzite ridge. Assays of up to 4.5 g/t gold have been reported in this zone.
The only two RC holes drilled have tested part of a possibly large mineralized system.
