AuRo Resources, a mineral exploration company, has released the auger program results at its EL Tesoro property. The assay results were obtained from 14 rock and 33 rock soil samples, totaling 47 samples.
A hand auger was employed to take the soil samples, wherein every sample was mined in a depth from 2.0 to 7.5 m. Panel and channel sampling were conducted to take the rock samples. Gold assay results from rock soil sampling and rocks have shown the presence of structurally controlled gold mineralization, linked to epithermal quartz veinlets and veins.
The company has found a strong occurrence of hydrothermal activity over the region enclosed by the auger program at El Tesoro property. Hydrothermal quartz veins were continuously found in several soil samples. The occurrence of hydrothermal veins indicates the possibility for mineralized gold in the property.
The results vary from low to high detection of 0.95 g/t Au in the 14 rock samples. Gold in soil anomalies were found in 11 rock soil samples out of 33, with values averaging up to 89 ppb gold initially.
SGS in Medellin prepared the soil samples, which were then tested by SGS in Peru. Fire assay with atomic absorption finish (AAS) were used for analyzing gold. Gravimetric finish and fire assay were conducted for any over-limit samples exceeding 5.0 g/t. A hydrochloric + nitric acid digestion together with inductively coupled plasma mass spectrometry finish and inductively coupled plasma atomic emission were employed for testing a group of 50 elements.
