and to the East ..El Tigre is located 4 km west of the Las Peñas base camp. It was discovered by one of the Aurelian regional stream sediment sampling program teams in late 2004. Coarse angular gold was panned from small streams that drain the area. The gold in streams was traced back to a point where gold in colluvium (weathered in situ) could be panned. This point was used to launch a detailed follow-up program.
Gridding, soil sampling, geophysics (magnetics) and mapping have since been completed which defined a 700m (NNW) by 400m (ENE) gold anomaly. Limited hand trenching and pitting have also been conducted, but have so far failed to find the source of angular alluvial and colluvial gold.
The area is underlain by intermediate porphyritic intrusive rocks, strongly altered and weathered. Areas of sericitic and chloritic alteration have been mapped. Tectonically brecciated crystalline quartz veins with iron oxides up to 4m in width have also been intersected in trenches and boulders of 1m float found in the quebradas have assayed up to 6.62g/t Au. Smaller, centimeter scale, veins and pieces of veins have been mapped in the trenches. A nugget of gold attached to crystalline quartz suggests that the coarse gold at El Tigre has come from similar veins. A 1m by 0.5m wide gossanous/pyritic boulder has also been found in a quebrada and assayed 0.58g/t Au, the source of this boulder has not been located.
